Architectural acoustics - Lab Report Example As far as the engineering is concerned, sound production has far-reaching implications on the environment. Sounds are pressure vibrations that travel in mediums such as gases, liquids and solids. The most common type of sound perceived by human ear is that which travels through air. Sound could be constructive or unconstructive. However noise is generally regarded as unwanted and destructive sound. In work environments or even in home setting, it is preferred that noise should be reduced effectively since it can affect the ability to work, concentration and rest. These noises range from loud music, traffic and building services (air ducts, pumps etc.) to neighbor activity. Noise production is still rated as one of the serious rampant forms of environmental pollution. Noise pollution continues to affect human health, as well as behaviors. Noise pollution has the can trigger annoyance, as well as aggression. Noise is also associated with high stress levels, disturbance of sleep, hypertension and tinnitus. It is worth noting that stress and hypertension are among the current serious threats to human health. Loud noise can also trigger cardiovascular diseases, resulting from increased blood pressure caused by noise. Noise does not only affect human beings, but also other organisms. For example, noise can affect wildlife by increasing the death risks by triggering an incapability of the predators to detect the prey. Introduction of noise in the new ecosystem can also reduce the portion of a usable habitat by either scaring away organisms or threatening them to extinction through the harmful consequences. Thus, process of curbing noise pollution is critical In this regard, curbing the amount of noise has been one critical area for engineers in their quest for sustainable development and production processes. Environmental engineers have defined the ability to control sound in a closed environment as Architectural Acoustics. Designers and engineers have studied

The Kepler Mission Research Paper Example | Topics and Well Written Essays - 1250 words

The Kepler Mission - Research Paper Example By observing the activity of the other planets and stars in the galaxy, the NASA informs human activities thus making the earth a safer place. The other planets and the star orbit revolve around the earth. This implies that the space consists of numerous movements thus increasing the likelihood of collisions (Shipman, Wilson & Higgins, 2013). The authority has determine past crashes on earth thus informing safety precautions in order to avert the loss of lives associated with such activities. The devise monitors the activity on the earth’s Milky Way. Fixed in a particular point of view in the Milky Way, the spacecraft maintains an integral view of the earth’s habitable zone. The spacecraft thus monitors the movement of other planets and stars on the path thus informing the safety and stability of the earth. The main instrument in the spacecraft is known as photometer with which it discovers ad monitors the lights emitted by the other stars on the Milky Way. The device t hen transmits the dates it discovers to the NASA offices on earth for analysis. The analysis always portrays the periodic dimming of the stars and the possible effects on both the earth and their host stars (International Astronomical Union, Pont, Sasselov, Holman & International Astronomical Union, 2009). The spacecraft observes the movement and activity in the space. In doing this, it observes both the light and sound emitted by the other stars orbiting around other planets on the earth’s Milky Way. Launched in 2009, the spacecraft that is part of the massive NASA’s discovery project had a timeline of three years (Marett-Crosby, 2013). However, the project has encountered several challenges most of which have influenced the rescheduling of the dates and the timeline of the project. Among the preliminary challenges to the project was the noise produced by both the machine and the stars in the space. The two impaired the data collection process thus informing the resch eduling of the dates as the association sought to rectify the anomalies. Additionally, in May 2013, one of the reaction wheels of the spacecraft failed thus resulting in subsequent receives and rescheduling of the dates. Goals Kepler maintains a dedicated observation of the earth’s Milky Way relaying fundamental information about the relationship and activities in the earth’s Milky Way. In doing this, the machine explores the structures and diversities of the earth’s planetary system. The information obtained from such studies help inform the activities and movements of people on earth. Some of the movements on the earth’s Milky Way possess substantial danger and security threat to the Earth. Some of the stars move on the earth’s orbit thus presenting potential security threats. The spacecraft observes the speed and closeness of such moving stars thus obtaining the specific dates of impact among others. The project’s goals include the follow ing: To determine the number of earth size planets lie on the earth’s Milky Way. To determine the sizes, ranges and shapes of the planets To estimate the number of planets on the earth’s habitable zone, in doing this, the spacecraft observes the size, the brightness, mass and density of the planets on the earth’s Milky Way. Dedicated monitoring of the space by Kepler among other scientific mechanisms employed by both the NASA and other scientific bodies globally is important in determining the safety of the earth. Kepler uses photographic lenses in capturing

Term examinations Essay Example for Free

Term examinations Essay In comparison to end of term examinations, teaching students by continuous assessments is better. In most primary, secondary and tertiary forms of education, the latter method of evaluating students is used. This form is most common and is used in most parts of the world due to many reasons. Continuous assessment is a more accurate method of evaluating students. This method is more appropriate in higher education as it ensures students study and go through lectures and notes if not every day at home, then very regularly as doing bad in any quiz or test may affect their grades or overall marks. Due to this, students actually go through the notes they take often to do well. This helps them remember and at the end they don’t have to cram just before the final exam like they would have to if they only had to sit for end of term examinations. In other cases, many students may also have a psychological problem of giving exams. Due to this they may do badly in their exams even though they may know their subject very well. They may be brilliant in class, participate well, attend all lectures but even then in the end of term exams they may not do well. This can be due to a phobia of examinations or simply the pressure of last minute studying. Due to this, taking tests or quizzes throughout the term, semester or year along with class participation is a better method of evaluating a student. At the same time, last minute cramming right before the finals may ensure that students do well in the term end exams. However, if students memorize right before their exams they may not remember what they learnt later as they may have been under too much pressure and stress while studying in the end. Even though they get the grades, they do not remember what they learnt afterwards and then cannot use it later in life. Therefore what they studied becomes useless since they cannot utilize what they learnt in their lives. Many students may also not have the capability to memorize. This means they will not do well in term end exams as they will not be able to memorize and will not be able to write in the exam. Many students also lack conversational and presentation skills. These skills are necessary in life especially at work. Thus, these skills need to be developed and enhanced. These can neither be developed nor enhanced if only term end examinations are taken. To bring about this development, teachers have to take continuous presentations etc in order to help students converse and communicate. In this manner as well, continuous assessment is better than term end examinations. Thus due to such reasons, I think continuous assessment is a better way of teaching as it helps students grasp more knowledge and utilize it later. This method also enhances certain skills which will surely help the students in finding better opportunities in their future.

Bureau of Alcohol, Tobacco, Firearms and Explosives

Bureau of Alcohol, Tobacco, Firearms and Explosives Kareem Canty Introduction The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is an agency within the United States Department of Justice. The Bureau of Alcohol, Tobacco, Firearms and Explosives protects American citizens from dangerous and illegal activities involving, as its name suggest, alcohol, tobacco, firearms and explosives.â€Å" The mission of The Bureau of Alcohol, Tobacco, Firearms and Explosives is to conduct criminal investigations, regulate the firearms and explosives industries, and assist other law enforcement agencies. This work is undertaken to prevent terrorism, reduce violent crime and to protect the public in a manner that is faithful to the Constitution and the laws of the United States (The Bureau of Alcohol, Tobacco, Firearms and Explosives). Though The Bureau of Alcohol, Tobacco, Firearms and Explosives is a law enforcement agency one of the primary responsibilities is tax collection. The Bureau of Alcohol, Tobacco, Firearms and Explosives is responsible for taxes on alcoh ol, tobacco, ammunition, and firearms. The Bureau of Alcohol, Tobacco, Firearms and Explosives is an important agency protecting Americans. History of the Bureau of Alcohol, Tobacco, Firearms and Explosives The Bureau of Alcohol, Tobacco, Firearms and Explosives has been the sole agency responsible for regulation and taxation of the above mention categories since July 1st 1972. However, some of the duties of The Bureau of Alcohol, Tobacco, Firearms and Explosives have existed in some form in the United States since 1789. Initially, these activities were performed by the Department of Treasury. On July 1st 1862, the Office of Internal Revenue was founded. This new agency was now responsible for all taxes, including those on alcohol and tobacco. The Office of Internal Revenue included enforcement agents to pursue those who evaded taxes. In 1919, the Volstead Prohibition Enforcement Act and the Eighteenth Amendment to the Constitution made it illegal to produce or transport alcohol. Enforcement of these policies fell on the Office of Internal Revenue. In 1920, the Prohibition Unit was created. This agency was made up of the agents focusing on liquor laws. On April 1st, 1927 the Prohibition Unit officially became a bureau under the Treasury Department. Congress established a new Bureau of Prohibition under the Department of Justice in 1930. This new bureau was now responsible for enforcing Prohibition. Then, the Treasury Department was still responsible for the tax and regulations associated with Prohibition, under the new Bureau of Industrial Alcohol. In December 1933, the Twenty First Amendment to the Constitution ended Prohibition. Shortly after, President Roosevelt created, via executive order, the Federal Alcohol Control Administration to regulate the newly legal industry. This agency was replaced in less than two years by the Federal Alcohol Administration (FAA). The FAA was founded as part of the Treasury Department, who was again responsible for supervising the alcohol industry. In 1934 the Alcohol Tax Unit was founded as part of the Bureau Of Internal Revenue. The FAA combined with the Alcohol Tax Unit. Prohibition, though over, resulted in a lasting culture of organized crime. Due to the violence resulting from organized crime, the National Firearms Act was passed in 1934 and the Federal Firearms Act passed in 1938. These Acts regulated firearms, largely via taxes. In 1942, the enforcement capacity of firearm regulation was entrusted to the Alcohol Tax Unit. Around this time, the ATU became known as the Alcohol Tax Division until the 1968 Gun Control Act. With this act, the Bureau of Alcohol, Tobacco, Firearms and Explosives was now responsible for additional substances, including explosives. In July 1972, the Treasury Department Order NO.120-1 officially shifted all activities involving alcohol, tobacco, firearms, and explosives from the Internal Revenue Services to the Bureau of Alcohol, Tobacco, Firearms and Explosives After over one hundred years of restructuring, The Bureau of Alcohol, Tobacco, Firearms and Explosives has finally achieved stability in its structure and its dut ies. One major change the Bureau of Alcohol, Tobacco, Firearms and Explosives has undergone was its adoption of anti- arson enforcement. In 1982, congress amended the original legislation that outlines the duties of the Bureau of Alcohol, Tobacco, Firearms and Explosives to include arson. Since the 1970s the Bureau of Alcohol, Tobacco, Firearms and Explosives has grown both its budget and its staff. The Bureau of Alcohol, Tobacco, Firearms and Explosives has added over a thousand employee positions. Since 1973, the Bureau of Alcohol, Tobacco, Firearms and Explosives budget has increased from $74 million to $1.07 billion (The Bureau of Alcohol, Tobacco, Firearms and Explosives). Budget In 2013 the Bureau of Alcohol, Tobacco, Firearms and Explosives total budget was $1,153,345,000. This budget covers The Bureau of Alcohol, Tobacco, Firearms and Explosives staff, operations, and programs. Though the Bureau of Alcohol, Tobacco, Firearms and Explosives collects taxes, that money does not found The Bureau of Alcohol, Tobacco, Firearms and Explosives activities. From the years 2007-2011, the ATF collected over $112 million. This money is turned over to the Treasury Department General fund. The funding from The Bureau of Alcohol, Tobacco, Firearms and Explosives comes from federal government. Before each fiscal year, the Bureau of Alcohol, Tobacco, Firearms and Explosives submits a budget draft to congress. The draft includes information about the allocation and purposes of their requested funding. Congress edits and revises the budget as they see appropriate and then grants the funding to the Bureau of Alcohol, Tobacco, Firearms and Explosives. This budget includes salar ies of The Bureau of Alcohol, Tobacco, Firearms and Explosives 4,937 staff employees (The Bureau of Alcohol, Tobacco, Firearms and Explosives, 2012). International Partners Though The Bureau of Alcohol, Tobacco, Firearms and Explosives is responsible for enforcing laws in the United States, they also work along international organizations. The Bureau of Alcohol, Tobacco, Firearms and Explosives works international to investigate and prosecute international crime. Some examples of these organizations include the United Nations, Interpol, and the G8. The Bureau of Alcohol, Tobacco, Firearms and Explosives has field offices in several other countries. They work alongside law enforcement, government officials, and policy makers in these countries. For example, The Bureau of Alcohol, Tobacco, Firearms and Explosives has offices in Canada, Mexico, Europe, Colombia, El Salvador, and the Caribbean. The Bureau of Alcohol, Tobacco, Firearms and Explosives has the most offices in Mexico, with five field offices in the country. Domestic Partners Since its beginning, The Bureau of Alcohol, Tobacco, Firearms and Explosives has worked closely with multiple other governmental agencies. Early on, The Bureau of Alcohol, Tobacco, Firearms and Explosives worked with the Treasury Department and the now nonexistent Federal Alcohol Administration. Today the bureau works closely with state and local law enforcement. The Bureau of Alcohol, Tobacco, Firearms and Explosives works with state and local law enforcement to implement laws and regulations, as well as to locate and prosecute those who break these laws. Also, the ATF’S leaders work with Congress on evaluation and budgetary matters. In â€Å"The American System† by Morton Godzins, the American government is described as very chaotic. Godzins discusses how multiple branches and agencies of government often overlap in function. He writes that successful collaboration requires agencies to openly communicate. To describe the intermingled functions of government, Godzin uses the analogy of a marble cake. This image illustrates the mixing of government functions as chaotic and unordered (Shafritz and Hyde, 2011). THE BUREAU OF ALCOHOL, TOBACCO, FIREARMS AND EXPLOSIVES Today The Bureau of Alcohol, Tobacco, Firearms and Explosives today serves the same purposes as it did when it was founded. Their scope has grown to include numerous activities that are relevant to their purpose. The Bureau of Alcohol, Tobacco, Firearms and Explosives organizes its activities into ten core functions. These functions include original objectives, such as alcohol and tobacco, the criminal firearm usage and trafficking and regulation of the firearms industry. In the 1970s, the Bureau of Alcohol, Tobacco, Firearms and Explosives began including explosives, bombs, bombing, and the explosive industry in their responsibilities. As previously mentioned, the Bureau of Alcohol, Tobacco, Firearms and Explosives began to investigate Arson in the 1980s, adding it to their core functions. The three remaining functions are more recent additions. The first of these additions is a focus on criminal groups and gangs. This activity is closely a lined with the Bureau of Alcohol, Tobacco, Firea rms and Explosives’ mission and values as criminal activity often involves the usage, purchase, or trade of the materials regulated by the bureau. The final two functions involve management activities and are also included in the strategic goals of The Bureau of Alcohol, Tobacco, Firearms and Explosives. These functions involve the Bureau of Alcohol, Tobacco, Firearms and Explosives’ workforce and modernization. The Bureau of Alcohol, Tobacco, Firearms and Explosives is constantly seeking to maintain and build a highly skilled staff. The Bureau of Alcohol, Tobacco, Firearms and Explosives seeks a diverse and talented employee base. The final function, modernization, is a focus of many government agencies today. The Bureau of Alcohol, Tobacco, Firearms and Explosives aims to improve upon its technological skills in order to remain effective and relevant in todays world. Strategic Goals In 2010, The Bureau of Alcohol, Tobacco, Firearms and Explosives published its strategic goals for 2010-2016. Four of the six goals focused on activities relating to the mission of. The Bureau of Alcohol, Tobacco, Firearms and Explosives These goals involve illegal firearms trafficking, criminal groups and gangs, explosives and bombings, and fire and arson. The remaining goals involved management activities. Those goals relate to work force and modernization. Over the past four years the Bureau of Alcohol, Tobacco, Firearms and Explosives has implemented changes where needed in order to meet these goals. All of these goals contribute to The Bureau of Alcohol, Tobacco, Firearms and Explosives vision, â€Å"We protect America. We protect your community.†(The Bureau of Alcohol, Tobacco, Firearms and Explosives) The Bureau of Alcohol, Tobacco, Firearms and Explosives two management activities, modernization and work force seek to improve the internal operations of the Bureau of Alcohol, Tobacco, Firearms and Explosives. Their modernization goal consists of modernizing business activities. This goal also involves updating procedures for information sharing and knowledge management. Finally, this goal also seeks the implementation of more innovative technology. The second management goal of the Bureau of Alcohol, Tobacco, Firearms and Explosives attempts to improve its work force by attracting, developing, and retaining a strong work force. Both of these goals aim to keep the Bureau of Alcohol, Tobacco, Firearms and Explosives operating at its full potential. Victim/Witness Assistance Program Since the Bureau of Alcohol, Tobacco, Firearms and Explosives focuses on illegal activities, the agency frequently interacts with victims. In order to guarantee victims receive their rights as specified in the Crime Victim Rights section of Federal Law 18 United States Code, Section 3771, The Bureau of Alcohol, Tobacco, Firearms and Explosives established its Victim /Witness Assistance Program in 1999. This program enables the Bureau of Alcohol, Tobacco, Firearms and Explosives to provide victims with various types of support. The Victim/ Witness Assistance Program ensures victims’ safety, as well as providing them with other resources. These resources include, but are not limited to, on financial assistance, recovery of property, and referrals to other relevant support agencies. These support agencies can provide services such as emergency housing, counseling, and support groups. The Victim/Witness Assistance Program is implemented by twenty three Victim/Witness Coordinators. These officers can be found in each of the Bureau of Alcohol, Tobacco, Firearms and Explosives field divisions located the across the country. These coordinators work closely with the United States Attorney’s Office, which has its own Victim Witness Coordinators. The Victim/Witness Assistance Program also works with the previously mentioned support agencies. These agencies can be located at both state and local levels. The program Coordinators also worked closely with local law enforcement agencies, especially concerning the safety of victims. While I found no criticism of the Victim/Witness Program, I also found no praise of the program. There seems to be little information available from other sources about this program. This is most likely due to the fact that the program is largely confidential and is only experienced by those who truly need its services, victim irrelevant crime. Conclusion The Bureau of Alcohol, Tobacco, Firearms and Explosives exists in order to protect American citizens and to keep their activities in line with the law. The bureau enforces laws and regulations intended to keep Americans safe. They are responsible for regulating the manufacture and trade of weapons and explosives and for controlling and preventing drug trade. Without The Bureau of Alcohol, Tobacco, Firearms and Explosives, the United States government would have a very difficult time regulating these trades and enforcing these policies.
