Mirror Lab Essay Example

Mirror Lab Paper Mirror Lab BY viiU523 One air inhalation hazard I observed during the Mirror Lab tour was for rhodite 906. In a large open room and workspace, the mirror lab utilized rhodite frequently to polish large new mirrors. This is concerning because this is a hazardous dust particle with its particle size at about 1. 5 micrometers. The movement of these particles are heighted by water mist placed above the mirror to keep the rhodite from solidifying. The employees also sprayed down the mirror frequently which further caused these particles to move around. When we were walking beneath and to the side of the mirror, orange rhodite compound could be seen on the sides of the mirror as well as the ground. The employers Job was to make sure the mirror was properly and consistently being polished. This definitely can poise a threat and safety risks to the workers. As a risk assessor, it is essential to decrease exposure and limit the spread of rhodite 906. Hazardous chemicals such as rhodite can cause harm when they enter the body in sufficient amounts via inhalation, ingestion, or skin absorption. The ature of the chemical hazard and the routes by which it enters determine the controls needed. Unfortunately, I did not observe such controls in the workplace. There were no material safety data sheets visible or chemical hazard warnings. The employer simply wore a lab coat while visitors were only asked to wear closed toed shoes. There were no guidelines, PEL, or TLVs given by OSHA. However, the material safety date(which should be posted) explains that it can cause irritation of the skin, eyes, and mucous membranes.

People can come into contact most easily by inhalation. In order to quantify the amount of air exposure, I would employ biological monitoring for the employers who monitor the polishing. The levels of chemicals in the body can sometimes be measured in the blood, urine, or exhaled air. The results would provide an estimate of the actual dose absorbed into the body. The MSDS lists ingredients in the rhodite we could monitor such as lanthanum fluoride, cerium fluoride, praseodymium fluoride, and kaolin. As a risk assessor student I would uggest controls such as safety glasses with side-shields used by employers and visitors alike. Engineering controls would include a local exhaust ventilation to control dust exposure without compromising the polishing ability. For skin protection, I would enforce those who have had contact to was their hands afterwards. Systems should also ensure that work wear does not become contaminated with dust, which would be carried away from the work area into mess rooms or other areas. Although the engineering controls may be less feasible, the other controls are a matter of dministrative enforcement and selling the importance of these safety measures to all employees of the mirror lab. One of the physical hazards I observed during the mirror lab tour was with noise levels. Those noise concerns ranged from the air cart, generator, and machine shop. The machine shop in particular concerned me with all the overlapping sounds. Many of the tools utilized such as the machines used to cut the mirrors created active levels of sounds. They had decibals exceeding 100dbl. The workplace was in a some air ventilation and air flow. Ear and eye protection were also provided. This does not bold well when compared to OSHAs permissible exposure limit which is 90 dBA for an 8 hour TWA. Because noise levels can cause hearing loss, OSHA requires employers to have a hearing conservation program in place if workers are exposed to a time-weighted average noise level of 85 dBA or higher over an 8 hour work shift. According to the presentation in class, some machines alone exceed 100 dBA. Using a sound level meter attached to employees, I would monitor the noise levels generated y various pieces of lab equipment to identify equipment that has excessive noise levels to verify these measurements. When equipment exceeds these limits(which according to our presentation, it did), it is important to manipulate engineering controls, posting of warning signs, and hearing protection options. I personally observed several warning signs and MSDS provided by the employer. Moreover, I saw several hearing protection devices available to employees. To improve on the conditions, I would move noise-producing equipment such as freezers into another oom. Moreover, the mirror lab could place compressors for controlled-temperature rooms in a remote location. Finally, I would provide acoustical treatment on ceilings and walls. Because there are equipment that exceed the 85 dBA set by OSHA, it is extremely important for employers to moniter the amount of time a person can be exposed in the machine shop. Although the standard is an 8 hour shift, if employees are always around the sound-exceeding machines, the amount of time a person can be exposed is cut by more than half.

Steganography - Essay Example Various data sizes are embedded onto the images and PSNR is also recorded for every image evaluated. The current media and communication domain is subjugated by digital multimedia artifacts. In essence, digital content usage has turned out to be a reality to most individuals. Nevertheless, with the exception of its daily usage, digital media play a significant role in research and academics. Media facilitated the access to essential resources, training of essential skills and efficient time management. However, the information processing tasks which are performed by such media, still need to develop significantly. Through embedding; intended to connect two data types and improve the metadata capacity, steganography might come handy in resolving this issue. In the given research, the author seeks to undertake an analysis of digital multimedia and its effects on numerous aspects of human life, through the inclusion of spatial domain of steganography. As specified, the analysis will be undertaken through the least significant bit subscription scheme (LSB). The selection of research methodology was preset by the high levels of simplicity, remarkably huge hiding capacity, and the essence that it relies on such particulars of human eye as the insensitivity of low bit images. When stereo-image has not to be choked by the SDDS system, there is need to have messages embedded at a specific spot; thus offering maintenance to the statistical aspects on the cover page. Examining the spatial domain embedding technique, which limits the selection of a given position as a result of the message distribution regularity, it is clear that the process of embedding a message in a specific location would be faced by a number of challenges including: definin g the changes in the spatial project. With the subject project, the mapping technique would be utilized so

Jain Architecture Essay Example for Free

Jain Architecture Essay Summary Jainism is a religion, based on ‘non violence’ and ‘self control of the human senses’. It has its origins in India. Jains are idol worshippers, and a temple is a place where this worship is carried out. Jain places of worship in India are unique in many respects. Temple cities are built atop hills at a considerable height from the sea level. Palitana, Delvada and Sametshikhar are classic examples of cluster of temples built on the top of hills. These were built during the times when the only technology available was hand work. Ranakpur and Shramanbelgoda are other classic examples of architectural masterpieces emerging out of devotion to idol worship. A photographic exhibition on these five sites is proposed. It will try to explain the uniqueness of temples at each of the sites. It would be an effort to demonstrate to the world, the marvelous results faith can bring. Attention would also be paid to the extensive use of marble as a material of faith ( the idols) construction ( the structures) and decoration ( the pillars and the domes) of Jain temples. The team will visit each of the sites and shoot the required still pictures. Specialists on each of sites will be personally interviewed to understand the architecture of each site as a form of art. So far, much work is not done on documentation of Jain architecture. Nor is there any authentic analysis available to see them as a form of art. For examples the basic geometric principles of Jain temples are hardly documented. The final form of the exhibition will be a series of still photographs, sketches or drawings or maps supplemented by text. This will make a comprehensive presentation of Jain temples as a form of art. Scope: The scope of this exhibition is to communicate the uniqueness of Jain architecture, mainly the five most popular sites in India, namely, Sametshikhar, Palitana, Delvada, Ranakpur and Shramanbelgoda. The medium used is still photography, supported by drawings, sketches and written text. All the photographs will be shot on 35 mm format. All the information will be displayed on panel size 4 ft X 3 ft. Each site will be allotted 10 panels, making it 50 panels in total. Each temple site will be documented as an independent module, to facilitate erection at any place in future. Leaving proper space between two modules will ensure a smooth human flow, while the exhibition is on. The exhibition is not to be viewed from a religious or a philosophical point of views, but as a form of art. It will expose the onlooker to how Jains incorporated the element of art into their ‘places of worship’. All the five sites chosen for this exhibition are in India. Sametshikhar, in the state of Bihar, can be compared to Mecca of Jains. This is the place where most of the 24 ‘tirthankars’ of Jains, attained their ‘nirvan- freedom from the cycle of rebirth’. Temples are built on the top of an array of hills as a mark of respect to each of them. Palitana, in the state of Gujarat, is a city of temples on the top of a hill, where the first ‘ tirthankar’, prayed. Delvada, at Mt. Abu in Rajasthan is well known for its intricate hand carving of large marble columns and the domes. Ranakpur, at the foot of Aravalli hills in Rajasthan, is again a rare piece of architectural marvel. It is a four sided temple, with 1,444 hand carved marble columns, in its interior. No art symbols on any of the columns are duplicated. The ceilings and the domes are also carved with symbols representing Jain beliefs. Shramanbelgoda, in the state of Karnataka in South India, is not a closed temple, but a single, huge idol of Bahubali. This idol is believed to be carved out of single piece marble.

They will also interview and talk to people who are experts on each of the sites. The same team on return, will edit the visual and the text material and prepare the final panels. This team will also be present at the site wherever this exhibition is held, to personally brief the visitors on the subject. This exhibition must happen, because of the uniqueness of its subject. Perhaps there is no such collective documentation existing, as yet. It would surely enlighten the onlooker. Works-cited page 1.

Friendship Essay: My Best Friend -- friendship essay, my best friend

She doesn’t know this, but she changed my life. She was there for me when it seemed like no one else was. When most of my friends were dissolving around me and I just didn’t feel like I could do anything right, she was there, and she made everything seem okay. It didn’t matter that I was inevitably going to graduate with a GPA a tenth of a point lower than I wanted, or that my director told me that he was disappointed in me because I just didn’t seem focused lately, or that my other friends just weren’t talking to me anymore. It didn’t matter because she was there and she made me feel safe. She’s my best friend, and I love her and admire her for so many different reasons. It seems that, no matter the situation, she knows exactly what will brighten my mood, whether it’s an hour-long venting session, a frozen yogurt run or sitting around a fire making s’mores. She has the incredible ability to make me laugh even when it seems impossible, through sometimes impractical means, like throwing marshmallows across the room or telling goofy made-up stories that may or may not be relevant to t...

Case Study Irs and Datawarehousing

Interactive Session: Organizations: The Internal Revenue Service Uncovers Tax Fraud with a Data Warehouse Case Study Questions: 1. Why was it so difficult for the IRS to analyze the taxpayer data it had collected? Initially, IRS data were stored in legacy systems designed to process tax return forms efficiently and organized in many different formats, including hierarchical mainframe databases, Oracle relational databases, and non-database â€Å"flat† files.The data in the older style hierarchical databases and â€Å"flat† files were nearly impossible to query and analyze and could not easily be combined with the relational data. 2. What kind of challenges did the IRS encounter when implementing its CDW? What management, organization, and technology issues had to be addressed? The challenges the IRS encountered when it implemented its CDW include: Management: Convincing the organization to undergo a sweeping upgrade like a data warehouse implementation was not easy, sin ce government agencies are normally risk-adverse and resist changes.Data warehouses require extensive effort to keep up-to-date. Organization: The structure of data wasn’t consistent because of tax law changes through the years. This made integration of the data a complicated process. The sheer amount of data that the CDW was slated to manage was far more than anything the IRS had previously handled. Data warehouses tend to require extensive amounts of money to keep up-to-date. Technology: The CDW has grown in capacity from three terabytes at its creation in the late 1990s to approximately 150 terabytes of data.The most important feature of the data warehouse was that it be sufficiently large to accommodate multiple terabytes of data, but also accessible enough to allow queries of its data using many different tools. The components that the IRS selected allowed CDW to do that. Conversion of the legacy data to the new system was not a uniform process. 3. How did the CDW improv e decision making and operations at the IRS? Are there benefits to taxpayers? The CDW enables highly flexible queries against one of the largest databases in the world.IRS researchers can now search and analyze hundreds of millions or even billions of records at one time using a centralized source of accurate and consistent data instead of having to reconcile information from multiple inconsistent sources. The CDW allows the agency to recoup many billions of dollars in tax revenue that was lost under the old system. In 2006 the IRS collected $59. 2 billion in additional revenue via 1. 4 million audits of taxpayers questioned for underreporting taxes. Using the data warehouse, analysts are able to determine patterns in groups of people most likely to cheat on their taxes.The data warehouse reduced the time it takes to trace mistakes in claims and analyze data from six to eight months to only a few hours. The CDW is more secure than the old legacy system storage tapes, thereby better protecting taxpayer data. 4. Do you think data warehouses could be useful in other areas of the federal sector? Which ones? Why or why not? Other federal agencies that might find data warehouses useful include: †¢ Department of Defense: maintain all personnel data from all four branches of the military including active duty, Guard, Reserve, and retired people.During times of war or national emergencies the data warehouse could supply information on people most qualified and available to respond to the emergency. All kinds of information and analyses could be performed if the data were consistent and complete. †¢ Federal Trade Commission: could combine data on consumer-related activities into one data warehouse that would be available to all branches of government and private organizations. Data could help analyze economic situations and factors so that businesses and governments could make faster and better decisions.
