Innocence in William Blakes The Divine Image Essay

Innocence in Blakes The Divine Image Blake was both a poet and an artist and he created many Illuminated works which combined the two. These forms, each powerful in their own right are even more so when used together as in The Divine Image. In analyzing this piece I will be looking at the elements and principles of art, the corresponding ‘elements and principles of poetry and how they support one another to convey William Blakes idea of Innocence. Elements are the fundamental building blocks used in either art or poetry. In art they are line, shape/form, value, texture, colour (which I wasnt able to deal with in this case as the only reproduction was black and white) and space. In poetry one might classify the elements†¦show more content†¦Without much use of form there isnt a need for deep space which is the illusion which makes the observer think the picture extends far beyond its true two dimensions. This is notable in its absence because it makes the use of negative space much more interesting (Negative space being the area around the actual objects in a piece). In this image the negative space becomes an interesting shape. I say line and shape are the most important of the elements, not just because they were used often but also because of how they contribute to the principles. The focal point in the picture is the flame-like object along the right edge of the print. It is the first thing to catch ones eye as it is the most complex area of the picture, having been built up with a lot of line and showing the most form of anything in the print. It is also the most ink filled part of the image and has very little space. It is the part of the picture which seems most solid. From the focal point we arrive at the first sort of movement which is the actual path ones eye tends to follow. Here line plays the distinctive roll of defining that path. Ones eye moves very quickly from the focal point to the title of the poem and then either down the poem itself or down the flame-like object to the figures in the bottom right-hand corner of the page.

Jewish, Early Christian, Byzantine and Islamic Art Free Essays

Teri Wilson March 1, 2010 Professor Hollinger Module 5 JEWISH, EARLY CHRISTIAN, BYZANTINE AND ISLAMIC ART Every religion has its own approach to art and architecture. An assessment between different traditions can offer an illuminating insight into the varying religious outlooks and theologies. Architecture, as well as art, is influenced by a number of forces in society, in the environment, in the psychology of the people who produce it, and in different institutions. We will write a custom essay sample on Jewish, Early Christian, Byzantine and Islamic Art or any similar topic only for you Order Now It is an expression of inner feelings and beliefs and so naturally is influenced by religion in many societies. Religious architecture is created to experience the sacred, to provide a place into which spiritual energies flow and reflect a sense of the divine. Some religions speak of art directly or have tenets which influence what can and cannot be depicted in art. The scriptures of these religions are the theological basis and shape the way people in express themselves, and this includes how they express themselves through art and architecture. The architecture in Judaism, Christianity, Byzantine, and Islam has important similarities and differences that are a result of the teachings of these faiths. In the first centuries C. E. , Jewish communities could be found in every corner of the Roman Empire. The archaeological remnants and literary attestations of more than 150 synagogues throughout the empire make clear that Jews were integral to the urban landscape of late antiquity, well beyond the borders of Roman Palestine. Asia Minor, in particular, was one of the most prosperous, Jewish communities (Stokstad, 164) The third-century synagogue in the Roman garrison town of Dura-Europos, Syria, like the Christian meeting house and the shrine devoted to the Persian god Mithras that stood just yards away, was adorned with sumptuous painting. The Wall of Torah Niche had splendid murals with narrative scenes from the Bible covered the synagogue’s walls; painted tiles of zodiacal symbols ornamented its ceiling (Stokstad, 165). Plaques with dedicatory inscriptions give some indication of the individuals and families who funded the building of such synagogues. In building their monuments, Jews often embraced the Greco-Roman practice of paving the floor with elaborate mosaics, many of which demonstrate an understanding of the second commandment injunction against image making that may surprise today’s viewer. In early Byzantine synagogues such as Hamman Lif in North Africa and Beth Alpha, Hammath Tiberias, and Sepphoris in Israel, specifically Jewish symbols—shofarot (ram’s horns), menorot (branched lamps), and Torah shrines—might appear alongside pomegranates, birds, lions, and fountains (metmuseum. rg). Zodiac wheels with human figures also find a prominent place in the pavements of several synagogues, dated from the fourth to the sixth centuries, as do scenes drawn from the Bible or allegorized images of the River Nile. After the destruction of the Second Temple by Roman emperor Titus in 70 C. E—an event commemorated on the Arch of Titus in Rome and in Jewish liturgy—images of the Temple’s furnishings, especially the celebrated gold menorah, or seven-branched lamp, became emblematic of Jewish religion. Marble sarcophagi favored by wealthy Romans were adapted for Jewish use by incorporating a stylized relief image of a menorah (metmuseum. org). In the catacombs of Rome, Jews placed gold glass disks representing the menorah and Torah arks at their tombs, as well as symbols of the festival of Sukkot just as Christians placed glass disks showing saints All these images reference the destroyed Temple and invoke a hoped-for messianic age when the Temple would be restored. So wide-ranging are the contexts for the menorot that it is clear the symbol frequently served merely to distinguish a Jewish monument or a Jewish patron. Seven-branched candlesticks appear in Roman and Byzantine art: in graffiti in the catacombs, inscribed on plaques, as a motif on seals, as decoration on glass bottles and on clay lamps all further testimony to the integration of Jews into late Roman and early Byzantine society (metmuseum. org). With the adoption of Christianity as the official religion, art was able, so to speak, to come above ground in the old pagan city of Rome, and painting, instead of being restricted to the decoration of the walls of the Catacombs or of small chambers and chapels, came into use on a large scale in the new churches that were at once set up. At the same time patronage moved from the hands of the poorer classes to the richer, and artists of outstanding quality came to be employed as well as those of obscurer character, who would work for small fees (www. religion-online. org). To wall painting was added the more luxurious art of mosaic; numerous sculptures were done, and minor objects, often in expensive materials, were in addition produced in the service of the Church, so that art production became at the same time both more extensive and more luxurious (www. religion-online. org ). A great deal of the work that was done at this time has of course perished, more especially that in fragile materials, such as textiles or paintings on panels, but a few mosaics of the fourth century and a good many more of the fifth survive in Rome, and there is quite a lot of sculpture, both on a large scale in stone and on a small in ivory. Something has already been said about the ivories, more especially the Consular diptychs, which necessarily form a part of the general picture, though it is not always easy to be sure of where they were made, as they are in a diversity of styles (www. eligion-online. org). Here we are concerned not so much with these things as with works which are essentially Christian and also undoubtedly Roman, such as the mosaics and wall painting, which are necessarily immovable or stone sculptures on a large scale in a material which was carved on the spot and quarried in the neighborhood. The earliest of the mosaics are those in the church of Sta Constanz a, which was built as an octagonal martyrium or tomb sanctuary between 306 and 337. It was converted into a baptistery in the fifth century, when the lateral apses were added. Only the mosaics on the roofs of the vaulted aisles are of the same date as the original building. This roof is divided into eight compartments, and there are different designs in each, though only those on the three sets on each side survive; they are in pairs, balancing one another on each side. These mosaics, which consist in the main of scrolls and other diverse motifs shown in isolation against a white ground, are very classical in character; they are virtually floor mosaics transferred to the roof. The mosaics which decorated the central dome have not survived, though there is a sixteenth century painting of them in the Escorial. They included scenes from the Old and New Testaments, bordered below by a river and separated one from another by caryatid figures, not unlike the dividing panels in the Baptistery of the Orthodox at Ravenna. In the apses which terminate the sides of the octagon to the north and south are figural compositions of a rather different character, depicting the â€Å"Traditio Legis†, where Christ conveys future responsibility for preaching on one side to Peter and on the other to Paul. Our Lord stands in the centre of each apse, with the Apostle before Him, against a background of trees (catholic-resources. org). The mosaics are probably to be assigned to the time of the building’s conversion for use as a baptistery in the fifth century. They have, however, been very much restored at subsequent dates, and to-day appear somewhat clumsy (catholic-resources. org). Those in the dome probably belonged to the same date as those in the vaults of the octagon. Another similar church of this kind is the Church of Santa Sabrina, a fifth-century basilica in Rome. The basilica, constructed by Bishop Peter of IIyria between 422 and 432 BC, is another must see (Stokstad, 170). Santa Sabrina, exterior is typical of the time, which is severe brickwork. In contrast, the interior displays a wealth of marble veneer and 24 fluted marble columns with Corinthian capitals acquired from a 2nd century building (Stokstad, 170). Christianity subject matter is the prime source of art up to the modern era. We find religious art in all styles and the major artists used Christianity in most of their paintings and built structures for Christian churches. In conclusion, it can be seen that art is not just one thing. It is a combination of devices which have taken thousands of years to grow and develop, through different religions, and through time. I personally feel that art is not something that we can define or even begin to describe. Art is to much a part of life to single out on its own or define, especially, religious art. Trying to write a summary on a general view of what art is is virtually impossible. Art, inside of every person is seen as something different and unique making the definition of art diversified for every person.

Internal Combustion Engine Fundamentals †Free Sample to Students

Question: Discuss about the Internal Combustion Engine Fundamentals. Answer: Introduction: Dimethyl Ether (DME) is an organic isomer of ethanol, it is chemically represented as CH3OCH3 (Semelsberger, Borup and Greene 2006). It is a colorless, volatile, non-poisonous, liquid compound used as fuel, aerosol, propellant, solvent and refrigerant (Semelsberger, Borup and Greene 2006). When DME burns a blue flame is observed (Semelsberger, Borup and Greene 2006). Both liquid petroleum gas (LPG) and diesel could be replaced by dimethyl ether. A variety of raw materials like natural gas, crude oil, residual oil, coal and waste products have been used to produce DME (Azizi, Rezaeimanesh, Tohidian and Rahimpour 2014). Among these raw materials natural gas management is the prominently used as it is widely available (Azizi, Rezaeimanesh, Tohidian and Rahimpour 2014). DME is synthesized either using the direct route by directly synthesizing DME from syngas using a single stage bi-functional catalyst or the indirect route by producing methanol from syngas and then purifying it and converting it to DME (Azizi, Rezaeimanesh, Tohidian and Rahimpour 2014). The advantages and disadvantages of using DME are that it has a high cetane number (Huang, Wang, Chen, Zhou and Jiang 1999), due to which it has better combustion quality than diesel management. Therefore, an engine designed to run on DME would have better efficiency and mileage. DME has no carbon-to-carbon bonds (Huang, Wang, Chen, Zhou and Jiang 1999) as shown in Fig.1 so it reduces particulate emissions (Sorenson and Mikkelsen 1995) and eliminates the need for costly diesel particulate filters. DME requires a fuel tank twice in size as that needed for diesel because it has half the energy density of diesel (Semelsberger, Borup and Greene 2006). DME has lower viscosity than diesel which increases leakage in pumps and fuel injectors (Semelsberger, Borup and Greene 2006). The lubrication issues present while using DME causes premature wear and failure of pumps and fuel injectors (Semelsberger, Borup and Greene 2006). In a diesel engine fuel mixed with air ignites under high pressure and temperature (Taylor 1966). This type of combustion is heterogeneous and takes place at constant pressure (Taylor 1966). Unlike spark ignition engines, compression ignition engines have no tendency to knock, hence they can operate at significantly higher compression ratios and have better efficiency (Heywood, 1988). In diesel engine fuel is injected at the end of the combustion stroke and burns mostly as a diffusion combustion which enables lean burn, thereby improving the thermal efficiency (Taylor 1966). A three-way catalyst cannot be used for after treatment due to the lean burn mode which complicates the after treatment system, thus increasing the cost and emissions (Heywood, 1988). GT-suite is a popular simulation software developed by Gamma Technologies which is predominantly used for 1D simulation studies. It is used to study gas exchange rate and combustion simulations using a 1D unsteady, non-linear Navier-Stokes equation. It finds application in understanding the effects of combustion, heat transfer, evaporation, turbulence and so on. There are two kinds of combustion models in GT-Power. Non predictive combustion model:- In this model the burn rate is imposed and does not depend on the in cylinder conditions to characterize combustion and emission patterns (Gamma Technologies, 2015). It has fast simulation time and is used to evaluate the concepts that do not have an impact on the burn rate characteristics, but is not used to study the concepts that have an impact on burn rate like injection timings (Gamma Technologies, 2015). Predictive combustion model:- In this model the burn rate is calculated for each cycle based on the in cylinder conditions. It is used to study the concepts that have an impact on the burn rate but requires longer simulation time (Gamma Technologies, 2015). Phenomenological predictive combustion models make use of zone modelling, where the combustion is modelled to take place in single or multiple zones. In single zone combustion model injection, evaporation, mixing and subsequent burning of fuel happen in a single zone (Barba, Burkhardt, Boulouchos and Bargende 2000). Whereas multi zone models work by dividing injected fuel packets into multiple zones, each of these zones are treated as open systems (Jung and Assanis 2001). Multi zone combustion provides better spatial resolution compared to single zone models thereby enabling better prediction of performance and emission related parameters (Jung and Assanis 2001). GT-suite software used to model diesel engine is discussed in the su cceeding section. GT-Suite software has two specific multi zone combustion models for diesel engines namely DI-Jet and DI-Pulse (Gamma Technologies, 2015). DI-Jet Combustion model:- It is a multi-zone, multi-phase, quasi-dimensional model wherein the injected fuel is divided into a number of axial splices, each containing five radial zones (Gamma Technologies, 2015).. Each zone is further subdivided into subzones containing liquid fuel, vapour-air mixture and burned gas (Gamma Technologies, 2015). This type of multi zone approach yields better prediction about emissions of the engine. DI-Pulse Combustion model:- It is a phenomenological, multi-zone combustion model used for predicting in-cylinder combustion and emission parameters for direct injection diesel engine (Gamma Technologies, 2015). It is a three zone combustion model which is significantly quicker than DI-Jet model (Gamma Technologies, 2015). This is achieved by dividing the cylinder volume into three discrete thermodynamic zones, namely the main unburnt zone, the spray unburnt zone and the spray burnt zone each with its own temperature and concentration (Gamma Technologies, 2015). Therefore, GT-Suite is a powerful software for conducting simulation studies in diesel engines. It has the requisite tools to evaluate the performance and emission characteristics of any diesel engine. Literature indicates that DME improves the emission characteristics of diesel engine without compromising on performance. GT-Suite could be used as an effective tool to validate the same. Research has to be carried out in reducing the size of the fuel tank, elimination of leakage in pumps and fuel injectors and improving DMEs lubrication properties so as to reduce the wear and tear of pumps and fuel injectors.

Take Home Questions Sociology 103 Take Home Questions 1. Ethnic stratification is a rank order of groups, each made up of people with presumed common cultural or physical characteristics interacting in patterns of dominance and subordination. To begin with, all systems of ethnic stratification are products of the contact of previously separated groups. Initial contact may be in the form of conquest, annexation, voluntary immigration, or involuntary immigration. Following contact, groups engage in competition, view one another ethnocentrically, and, ultimately, one imposes its superior power over the others, emerging as the dominant group. Ethnic stratification systems are created by the movement of people across national boundaries, usually bringing with them different languages and cultural systems, or by the establishment of new political boundaries. Multiethnic societies are formed through one or a combination of several contact patterns. The first factor critical to the emergence of ethnic stratification or inequality is Conquest. Conquest is a form of contact in which people of one society subdue all or part of another society and take on the role of the dominant group. European colonialism of the eighteenth and nineteenth centuries best exemplifies this pattern. The next factor to the emergence of ethnic stratification is Annexation. It is a political occurrence in which a part or possibly all of one society is incorporated into another. If a gathered society has a dominant group, then the ethnic groups within that society become subordinate at the point that sovereignty is transferred. Such annexation may occur in a peaceful or a violent manner. Following annexation, the most common patterns by which ethnic groups come into contact involve immigration. The immigration of peoples from one society to another may be either voluntary or involuntary. The chief source of ethnic heterogeneity in the United States, Canada, Australia, and New Zealand has been voluntary immigration. The chief objective of people who emigrate from their home society is ordinarily economic betterment though sometimes political or religious considerations play an important role. Demographers who study migration patterns refer to factors of ?push and pull? that motivate people to leave their original society and migrate to one that promises improved conditions of life. The ?pull? happens in times of economic hardship, people will be encouraged to emigrate if they perceive more favorable economic opportunities in another society. Depressed economic conditions, involving minimal job opportunities and low wages, along with a low expectation of betterment of such conditions, constitute the ?push?. Additional push factors were the increase in evictions by landlords and the unlikelihood of any major political changes that would have improved the economic situation. On the pull side, the most appealing societies were those in need of unskilled labor, like the United States and Canada, which were then in the primary stages of industrialization. Finally, Involuntary immigration involves the forced transfer of peoples from one society to another. Such forced movements are best exemplified by the slave trade of the seventeenth, eighteenth, and nineteenth centuries, which brought millions of blacks from Africa to work the cotton and sugar plantations of the United States, Brazil, and the West Indies. Lieberson's theory is that the nature by which diverse ethnic groups initially meet has been shown to be a critical factor in explaining the emergence of ethnic inequality and the specific patterns it subsequently takes. He distinguishes two major types of contact situations. The first type, migrant superordination, is illustrated by various colonial conquests in which a technologically and organizationally more powerful migrant group subdues the native population. The second, indigenous superordination, is characteristic of most voluntary and involuntary immigrations such as those to North America; in these cases, the arriving groups are initially made subordinate to a resident dominant group. Lieberson maintains that long-term conflict is more likely in societies where the indigenous population at initial contact is subordinate. Native groups less powerful than the arriving colonials are left with few options other than resistance to the new social order imposed on them. This hostility is further strengthened when the conquering group, over time, becomes itself an indigenous group. It is the relative power of the migrant and indigenous groups that determines the eventual nature of ethnic stratification in each of these situations. Where an invading group is successful in dominating the native population, the political and economic systems of the new group are imposed, and warfare and general conflict are likely to result quickly. Situations in which the native group wields greater power and immigrant groups enter as subordinates produce less overt conflict initially. The indigenous group retains control over the

Dipolmacy essays

Dipolmacy essays Diplomacy is a very important issue. Diplomacy is relations between nations, and is usually the talking part. If the situation gets out of hand it may result in war. The US has just had a major situtation with China and luckly it ended in with good results and not war. The problem started when a US ARA4 spy plane was flying in international waters about 80 miles off the coast of China. China became intimidated by the us and sent up highly monuverable fighter jets that got really close to the US plane. With the fighters in the spy planes blind spot, it began to bank to the right breaking a prapeller and causing a Chinese to fall to his death. The US plane then made an emmidait landing in China, where the crew of 24 were held as detaines. In the 20 minutes that the us crew had between making the emergency call to land and the landing in China they went through mandatory presedures of breaking every piece of equiment on the plane. The Us spy plane has the ability to tap into phone conversations and read e-mails. if chins figures out how to replacate our technology they could do the same and spy on us! Lets not look at all the bad parts of the story, one good thing is that the Chinese execepted our not so sincere apoligies and let the crew go. But they hadnt we could have gone to war. With the technology we have today (Nucleaur weapons) nothing will be good about a war. ...

International Banking Law and Capital Markets Assignment

International Banking Law and Capital Markets - Assignment Example There is a need to develop more stringent standards for the banks to address the deficiencies that come on the surface in the financial crises of late 2000. The introduction of Basel-111 aims at to strengthen the capital requirements of the bank and the regulatory requirement of bank liquidity and bank leverage. In Basel II, the risk management was out sourced to third party. The Ratings of financial instruments were conducted by the outsource agencies Fitch ibca, moody and poor and standard without intervention of official agencies. The AAA ratings on  mortgage backed securities,  credit default swaps  and other instruments in practice evidencing extremely bad credit risks. The implementation of Basel III surely will decrease annual GDP growth to the extent of 0.05 to 0.15 percentages. It is responsibility of the directors of the company to keep an eye on  market liquidity  condition that enables them to hold major assets for the accountability of material losses2. Require ment of Basel III The Basel III primarily addresses and focuses on the liquidity risk, capital adequacy ratios and stress testing. It requires banks to follow the requirement of Basel III and to compute the liquidity and leverage ratios accordingly. Therefore, the banks are to keep themselves align with the new requirement in order to integrate all relevant data to develop a new approach of data analysis and modeling. Basel III demands sufficient transparency and zero rated documentation ever than before to ensure that the deployment of funds would bear fruits3. Banks must ensure creation of new models that ensure compliance of Basel III requirement. It is a matter of fact that most of the institutions are reluctant to implement it in its true spirit due to reasons best known to them. However, they have no other option but to implement it in order to avoid penalty from compliance and monitoring watch dogs. In other words, compliance of Basel III requirement is mandatory and not opti onal. Keeping in mind the necessity, the banks are developing infrastructure and models for the banks to make best use of its capacity to pin point and respond to the profit making opportunities4. According to Simon Nixon, â€Å"no one disputes the broad thrust of Basel III, that banks should hold much higher levels of higher-quality capital. Indeed, all major European banks have well-developed plans to meet the new rules ahead of time.†5 It is a matter of fact that in today’s world each and every organization including banks heavily relies upon latest technology to meet the requirement of customer satisfaction besides regulatory compliance by the banks. The more efficient business decision making are based on the reliability of their quality data. Any bank who successfully receives the data through reliable domestic sources within the bank to position its data warehouse on sound footings coupled with technology infrastructure stands to deliver the goods efficiently in terms of compliance and better business6. â€Å"Basel III tightened up the rules on what could be counted as core capital, increased the risk-weights that determined how much capital a bank should hold against a particular exposure and finally introduced a tough new minimum ratio of core capital to risk-weighted assets, set at 7% for small banks and rising to 9.5% for the largest banks deemed

Taking a Stand Research Paper Example | Topics and Well Written Essays - 750 words

Taking a Stand - Research Paper Example This leaves students and lower level employees prone to bullying tactics such as being used as personal slaves by physicians or senior nurses ridicule and humiliate students in front of their colleagues and patients as well. Such bullying tactics differ with extremity depending on the organizational setup. There is a need for a moral agent within healthcare, among nurses since if this role is not fulfilled some of the detrimental effects include deflating of self-esteem which may disrupt their pursuit of the profession, low morale leading to employee turnover, absenteeism and low productivity affecting performance; all of which directly influence the success of the organization. Worse still, in some cases, the organization may end up incurring litigation fees, making out early retirement payouts, counseling fees for workers and compensation of workers. Therefore, it is apparent that individuals practicing nursing should take up the challenge of being the moral agent. Where they stand up and defend people being bullied, or if the one facing the bullying taking a firm stand regardless of the alienating position it leaves one in. It is unfortunate that there is no specific legal action open to majority of the bullying tactics present in the workplace. However, there are some laws under the Civil Rights Act and the Occupational Health and Safety Act that can be applied to certain scenarios if a protected class such as from a certain ethnicity is violated and if safety and healthful conditions are not met, respectively (Niles, 2012). As a moral advocate against aggression at the workplace, I would begin by informing fellow employees on the options open to them if they face any bullying. This would create a feeling of empowerment and confidence while carrying out their clinical duties and seeking knowledge from their seniors. Secondly, I would approach a senior physician and ask them to support my endeavor when I approach physicians to urge them to refrain from and w arn them about bullying through abuse of power or any other tactic. In order to get cooperation, I would educate the senior level nurses and physicians on the impact of bullying (Daly, Speedy and Jackson, 2003). By relaying this information, I believe it will create understanding on why it is important that any form of bullying be shunned and where one witnesses it, they should not tolerate it by merely standing by but instead rebuke the offender and support the victim. Thirdly, I would come up with a clear framework that defines what counts as bullying so as to avoid cases of misunderstanding. This would be contained in a document and placed in strategic positions within the hospital so that everyone can be informed and that no excuses of ignorance are allowed. Lastly and most importantly, I would encourage senior nurses to take up the role of mentors so as to support nursing students as this will not only benefit the students but will give them an opportunity to develop and nurtur e leadership skills, critical in advancing their careers (Randle, 2006). Concurrently, I would seek a concrete title that attracts attention from employees but does not deter low-level group from freely approaching me. This would ensure the position takes on a permanent standing within the organization, so that even upon my departure it continues

Describe the worst team experience you have ever had. What did you do Essay

Describe the worst team experience you have ever had. What did you do - Essay Example He asked me to fill in as head of our unit until they found an officer whos free and ready to take on. I gave him my worries of being a temporary superior to my team mates. The head promised me his full support in case of any insubordination. This was not a solution, I would still have to go back and work with these people once the new officer arrives. I decided I had to do my job as head of the unit, and still keep strong ties with my colleagues. I remembered Jim Collin’s level five leadership styles and was ready to undertake the challenging role (Collins, 2001). My colleagues became jealous of my new appointment. One of them swore not to take any orders from me, and stormed out of the room. The first 2 weeks in my position were a nightmare. People refused to due their work, or take any new assignments from me. But as tough as it was, I could not report them for that meant losing them. I felt like a juggler, trying not to drop a ball. As time passed, I realized all my team mates needed was equality. I decided to restructure our unit temporarily while I’m heading it. I gave each member a field where only he was responsible. They still had to report back to me, but I think it made them feel as if my appointment was just and administrative one, while in fact not much had changed. Not only did this strategy work for work relations, but our unit was doing better work than before. This worked right because my colleagues treated me well after I left the

Problems That Dry Lining Companies Frequently Encounter Construction Essay

Problems That Dry Lining Companies Frequently Encounter Construction Essay When the air barrier consists of plasterboard dry lining, dry lining companies have to omit the out of sight, out of mind approach that may have been implemented prior to the amended Building Regulation of Part L. Any defects in the construction of a liner wall subsequently show up in the pressure test. An air leakage audit is then required to identify the air leakage paths if the building fails the specified airtightness requirement. (www.mcconsultingengineers.ie) Generally the problem experienced by dry lining contractors is the interface junctions between two different elements, e.g. where the dry liner wall meets a column or a concrete wall. Problems may arise due to insufficient detailing, incompatibility of materials, lack of co-ordination between trades, etc. (www.bath.ac.uk) Remedial works to the air barrier may be very expensive, disruptive and prolonged for the dry lining contractor. Remedial sealing is therefore extremely problematic for the contractor. A way in which to enhance the air barrier is to ensure that subsequent trades do not compromise the air barrier. The air barrier may be compromised by another contractor accidentally damaging it or deliberately penetrating it in order to complete their work to programme of works. It is vital that the damage caused to the barrier be repaired immediately. (www.mcconsultingengineers.ie) Voids created in the walls for air ducts or piped services significantly reduce the probability of the room achieving its required airtight specification. A room with several penetrations is less likely to achieve a greater airtight value than a room with fewer penetrations, since service penetrations in and out of a building contribute as a major source of air leaks. (www.seda2.org) It is common for design drawings for dry lining contractors to contain little or no information on the location of the primary air barrier or airtightness issues. This ultimately results in those involved in constructing the air barrier for the building not being aware of the location, its purpose, the importance of maintaining continuity of the air barrier, nor areas of the construction where particular attention to detail is required to ensure airtightness. (www.leedsmet.ac.uk) A problem experienced by dry lining contractors is that the designers do not specify exactly where the airtight layer is on the drawing. The designer does not identify the airtight envelope on drawings for the contractor. Consequently on site the airtight envelope is not labelled, therefore other contractors are not aware of its location. The lack of awareness amoung contractors and designers is detrimental, e.g. if an operative needs to drill a hole through a dry liner wall or ceiling to thread pipes or cables through they are not aware that the penetration must be resealed afterwards. It is important that such penetrations are managed in a more controlled manner than they currently are from the dry lining contractors perspective. (www.bath.ac.uk) If joints are unavoidable then design-in a seal. This may be difficult for dry lining contractors as the method chosen to seal joints depends on the size of the gap between components, the amount of likely movement, the practicalities of application and the need for weather / air tightness. (www.mcconsultingengineers.ie) All buildings move to a greater or lesser extent depending on its use and this movement has to be accommodated in the design from the outset. This is troublesome for contractors as movement or expansion joints will need to address airtightness as well as movement. Not all joints do so, so careful deliberation is required during the design stage. (www.mcconsultingengineers.ie) Dry lining contractors are faced with a multiple of complex details for the external airtight envelope. Complex solutions to airtightness are likely to be more prone to poor execution and potentially to greater vulnerability to differential movement, failure of sealants, and dislocation of components etc. (www.environ.ie) (www.seda2.org) Due to a lack of information on the commercial sector, the author had to resort to the residential sector, as the basics are similar. One of the main air leakage paths within the UK dwellings is plasterboard dry lining (Stephen, 1998 2000). Problems arise with plasterboard dry lining when air can freely move into the gap between the plasterboard and the masonry wall, especially where plasterboard is fixed to the wall using adhesive dabs. The air gap between the plasterboard sheet and the masonry wall then act as a plenum, effectively interconnecting all of the leakage paths within the dwelling. (Johnston, Shenton, Bell, Wingfield, 2004:17) Figure 1 Discontinuous ribbons of adhesive used to seal plasterboard dry lining. (Johnston, Shenton, Bell, Wingfield, 2004:17) Service penetrations are known to be a significant route for air leakage (see Stephen 1998 2000). The report on Robust Construction Details (DEFRA, 2001) states that particular care on site should be paid to service penetrations and all service penetrations should be sealed with expanding foam or other suitable sealant, whether in the wall [Dry liner wall], ground floor, intermediate floor or ceilingà ¢Ã¢â€š ¬Ã‚ ¦ Observations from site illustrate that little attempt has been made to seal the majority of service penetrations through walls, ground floors, intermediate floors and ceilings, and where attempts at sealing have been made, the penetrations are generally inadequately sealed and inappropriate sealants have been used to seal gaps around the service penetrations. (Johnston, Shenton, Bell, Wingfield, 2004:19) Figure 2 Diagram illustrating sealing of service penetrations [Source: DEFRA, 2001] Site Supervision and Workmanship A major factor that influences air leakage is the level and quality of site supervision and workmanship during the construction of a building. Similar types of buildings with similar details may have very different air leakage rates. As a result workmanship is often citied as the primary reason why airtightness standards are not achieved in the construction sector. (www.leedsmet.ac.uk) From the authors personal experience during industrial placement all aspects of dry lining work needs to be inspected as work proceeds. It is extremely complex to inspect the airtight barrier on the building once work is complete on site, as it is generally covered by internal fixtures and finishes. Great awareness and concentration is required on inspection, to ensure that the air barrier is not defective in any way, paying particular care to parts that will be hidden on completion. (www.mcconsultingengineers.ie) Once awarded the contract and the air barrier consists of plasterboard dry lining, it is the dry lining contractors responsibility that the airtight barrier is achieved. A problem faced by contractors is that the employees are not aware as to their contribution and responsibilities for the overall airtightness. (www.seda2.org) Consequently the issue of good or bad workmanship in general is a key factor with air tightness. This is what makes the supervision and inspection for the dry lining contractors more difficult to control. (www.seda2.org) Due to a lack of information in the commercial sector regarding dry lining contractors site supervision and workmanship, the author resorted to the residential sector, as the fundamentals are similar. Stamford Brook is a development of around 700 cavity masonry dwellings being constructed on part of the National Trusts Dunham Massey Estate near Altrincham in Cheshire. At Stamford Brook an example of a perceived workmanship problem was the maintenance of a continuous ribbon of plaster adhesive around the perimeter of the plasterboard dry lining. It was observed that with very careful attention to detail and enough time allocated, a significant reduction in the level of air leakage was attained using plasterboard on dabs. (Miles-Shenton, Wingfield Bell) (www.leedsmet.ac.uk) Another conclusion from Stamford Brook was that it was impossible to divorce workmanship, not only from design but also from other issues of construction management such as training, communication and quality control. It was clear that many operatives were eager to carry out a high-quality job but that, as far as airtightness was concerned, it was complicated for them to be clear about what they had to do or who was responsible for achieving an airtight envelope. (www.leedsmet.ac.uk) Quality on site It is of paramount importance that all parties involved on the project from client, contractor and consultants to all site staff and operatives and off site suppliers understand the concepts of air tightness and how they are involved in playing a vital role to that aspect of construction. It only takes a minute section of the dry lining wall of the building to be permeable to ensure a failure to comply. This ultimately results in the remedial works which are costly for the contractor not to mention the impact it may have on the building programme as a whole with time delays. Therefore it is essential that an endeavour is put into practice to educate the staff and that all the staff works a team. Issues of thermal bridging, continuity of insulation and the correct construction of designed details need to be addressed to ensure that airtightness is achieved. (www.hrsservices.co.uk) Although airtightness testing is carried out a few weeks prior to practical completion of a project, it is vital that the dry lining contractor has a quality system in place so that remedial works are not necessary. Dry lining contractors should also try to obtain the airtightness test at a time where the barrier is complete and when remedial works are relatively simple to perform. The airtight test generally consists of two tests, once when the air barrier is complete and one prior to the handover stage. (www.seda2.org) Airtightness testing is generally carried out a few weeks prior to practical completion of a project. The airtight test generally consists of two tests, one when the air barrier is complete and the other prior to the handover stage. It is best practice that the dry lining contractors strive to achieve the required air permeability rate first time round. They then can improve that rate by addressing issues in the audit that is likely to accompany it. Dry lining contractors should also try to obtain the airtightness test at a time where the barrier is complete and when remedial works are relatively simple to perform. If for instance the air barrier is not complete but the main contractor is adamant of having an air leakage test. The incomplete barrier would have to be temporary sealed with an impermeable material; this is a timely and complex procedure. The result of the test may also prove to be an unfair reflection of the dry lining contractors work to date and the location of the le aks may be more difficult to locate. (www.hrsservices.co.uk) Quality Policies Dry lining contractors have not implement an enhanced strategic quality policy in order to succeed in maintaining airtight construction. Quality of workmanship and adequate construction of details are the main issues affecting companies to date. With the stringent Building Regulation in place, increased emphasis on quality policies have to be adhered to. (www.leedsmet.ac.uk) High-quality workmanship is obviously significant, but workmanship unfortunately always appears to be of poor quality due to the context in which the staff has to work. Stamford Brook studies have shown that Buildability of designs, lack of detailed design, lack of specific training and the lack of a general quality control procedure underlies many workmanship problems. If careful attention to detail and adequate time allocated, the method of airtight construction can increase dramatically. (www.leedsmet.ac.uk) Some issues that the quality policy may incorporate to enhance it are an improved management strategy, communication and quality control. Operatives are generally eager to construct to the required specification of detail but short cuts are taken in-order to complete the task in the required time. Operatives are not aware that they are responsible for the achieving the airtight envelope, and that the common trend of the past of cutting corners is not acceptable in the current practice of the industry. (www.leedsmet.ac.uk) Management On going review of the design is very important. The project management do not ensure that details of all design changes involving elements of the external envelope are distributed throughout the design, procurement and construction teams. This may have consequently effects for dry lining companies. (www.environ.ie) Not all project programmes reflects dry lining contractors required sequence for effective formation of the air barrier and insulation installation. Some trades are not permitted access to form not only the part of the insulation layer or air barrier for which they are responsible, but also to ensure that continuity is achieved between their works and that of other contractors. (www.environ.ie) An Air Tight milestone is not always included when compiling the programme. This puts immense pressure on dry lining contractors if the air barrier is fails the air tightness test. Ignorance of this date prevents management to schedule thorough envelope pre-test inspections and test dates in advance of the final product. (www.environ.ie) Once the air barrier consists of plasterboard dry lining, it is the dry lining contractors principal liability to deliver the air tightness performance overall and the most likely task on any but the smallest jobs will be the co-ordination between management. The contractor must be clear that he carries responsibility for the overall air tightness and in turn must ensure that all personnel and operatives are clear about the extent of their responsibilities. Experience suggests that the best performance has been achieved by contractors who employ a dedicated individual / team to carry responsibility for air tightness, to inspect the works and instruct as required. (www.seda2.org) The issues of air tightness are closely linked to issues of good or bad workmanship in general for contractors. This can make the issue more sensitive and more difficult to control. Even simple buildings are immensely complex and so the most important aspect of all is the creation of an overall culture of careful, tidy, accurate and airtight construction, something which can not be simply forced through a performance specification. (www.seda2.org) Communication Every year defects in the UK construction industry cost at least  £1 billion to rebuild or repair. A number of the defects are the result of poor communication, for example, an inadequately detailed drawing, operatives being given the incorrect instructions or technical information not being available. Improvement in communication should result in an increase in the quality of the build and a reduction in the level of defect occurrence. (projects.bre.co.uk) Studies at Stamford Brook have emphasised the critical nature of communication and the potential impact it may have on airtight construction. It is vital that there is an improvement in flows of information both upwards and downwards in the formal management structure in companys, an example of this may be operatives reporting an incorrect drawing to the site office and the site office will contact the main contractors office, where the incorrect detail can be rectified. (www.leedsmet.ac.uk) Frequently at Stamford Brook and many other sites observed throughout the UK, design information was not available, not at a sufficient level of detail, confusing, complex or just not referred to by operatives. This lack of information tended to lead to a rather diffused process as operatives followed their instinct rather than using detailed design information, which ironically was not present. (www.leedsmet.ac.uk) Also there did not appear to be any particular well developed mechanism for feed back of information on air tightness performance and specification. It was not clear how the design and construction lessons were being absorbed for use in making vital improvements to processes or actual designs. This can be linked with the necessity for a clearly defined quality control process, for without such a process there can be no definition of problems, identification of their causes or framing of solutions. (www.leedsmet.ac.uk) Majority of personnel and operatives involved in the procurement and construction of the building fabric are not aware nor understand the necessity for insulation continuity and airtightness. The lack of awareness associated with these issues, results in components being engineered out of the design for cost savings. (www.environ.ie) Awareness is not raised at key stages during a project, for example, briefing procurement offices and site tool-box talks. As a result parties can not clearly identify where and how insulation continuity and the air barrier are to be maintained. Operatives directly involved in constructing the insulation and air barrier do not draw attention to difficulties experienced on site or request direction. This lack of communication is likely to have detrimental effects on construction. (www.environ.ie) Operatives not directly involved in the building fabric are not entirely aware of the importance of insulation continuity, the air barrier and the flagging up of any breaches through these lines of defence. They do not remedy potential thermal bridges or air leakage routes brought about by their own activities, or to seek help from other trades, depending on the nature of the breach. (www.environ.ie) Quality Control Quality control is critically important to a successful construction project and should be adhered to throughout a project from conception and design to construction and installation. Inspection during construction will prevent costly repairs after the project is completed For construction projects, quality control means making sure things are done according to plans, specifications and permit requirements (Satterfield, 2005:1) Many dry lining contractors have no system in place for monitoring the quality of their processes and products. Experience illustrates those contractors without Quality Assurance (QA) hinders them to check for insulation continuity and air tightness. An effective QA control is that insulation continuity and air tightness are considered during all design changes and material substitutions affecting the external envelope. An ill-formed design change may jeopardise the final performance of the building envelope. The lack of a QA process in a company indicates that they do not inspect finished works especially the building envelope. This in turn prevents management to inspect that all works are properly constructed prior to being covered over. (www.environ.ie) Construction quality can have a significant impact on air tightness. An overwhelming conclusion from the Stamford Brook Field Trial and from general observation of the UK house building industry as a whole is that quality control processes are extremely diffuse with a number of actors playing similar but different roles which are almost always carried out in isolation. It is perhaps not surprising that with no clear air tightness quality control process in place, sequencing is often out of the phase and known errors tend to be repeated time and time again. (www.leedsmet.ac.uk) Another quality control issue observed at Stamford Brook that can lead to air tightness concern for contractors is the different tolerances that were constructed to by different trades. Items and components that are manufactured off site to high tolerances are often fitted into structures built by trades that are not operating to the same degree of precision. As a result, performance and workmanship issues can occur when construction is outside these tolerances. (www.leedsmet.ac.uk) Quality control is not a primary objective for all the members of a dry lining company. Managers do not take responsibility for maintaining and improving quality control. Employee participation in quality control is not sought after nor rewarded, for example the introduction of new ideas. Consequently, quality improvement is not served as a catalyst for improved productivity. (pmbook.ce.cmu.edu/13)

Generating Real-Time Visual Meaning for Live Indian Drumming :: Music Rhythm Drums Musical Essays

Generating Real-Time Visual Meaning for Live Indian Drumming Abstract: In this essay, a system developed to generate visual meaning for live performed music is described. Specifically, this system is calibrated to respond to North Indian classical and folk drumming tradition, using custom designed digital musical interfaces, such as the Electronic Tabla and Electronic Dholak. A drum, when struck, does not generate its sound as a record of the force applied, but as an artifact of a physical response to that strike within the artistically controlled conditions of its material state. With the design of the North Indian drum controllers, we developed a physical model for digital audio synthesis to recreate the aural qualities of the drums’ response under the control of the player. From there, we abstracted that concept to develop a dynamically responsive model for real-time rhythmic visual synthesis. In creating a visual experience for North Indian classical music, we sought to create a dynamic visual accompaniment with an appropriate ambience for the patterns and complexities of North Indian drumming. The design process was shaped by the need to react to a series of signals that would be received from the musician through the digitized musical interfaces, while giving a visual performer the ability to modify and shape those reactions over the course of the performance. In contrast to using a prerendered or abstract visualization, we aim to create an audiovisual composition which is both aesthetically compelling and responsive to the conditions of live performance, in addition to providing a meaningful visual context for what the performer is playing. In this essay, we will describe: - Veldt: a custom built application for visual expression of musical performance. - Digital Indian Drums: the Electronic Tabla and Electronic Dholak which digitize gestural information of a live performer. - Rhythmic visualization of our system used in live performances. Veldt Veldt is an application which was designed from the ground up for the purpose of visual expression and performance. It receives MIDI (Music Instrument Digital Interface) and OSC (Open SoundControl)[1] messages from digital musical interfaces and maps them to a system of reactive events in order to generate live visuals, which are rendered real-time using the OpenGL[2] graphics language. Mappings are flexible: sets of mappings may be arranged and modified during the design and rehearsal process, and triggered by control events during different movements of a performance, and arbitrary text, images, video, and geometric models may be used as source material.
