Energy Demand Essay -- Environment, Thermodynamics

1. Introduction Due to the economic growth, the energy demand of the world increase every year. In the energy conversion process in power plants and small engines, energy efficiency is a key factor. The equipments with higher efficiency, the more work output. Therefore, a number of researches studied on thermodynamics of efficiency, irreversibility and exergy in both spark-ignition and compression-ignition engines were found during the last century. The thermal efficiency and the energy loss in the system are normally calculated from the 1st law of thermodynamics, while the maximum work output or exergy is characterized by the 2nd law of thermodynamics. The exergy of a system from the 2nd law is defined as the maximum useful mechanical work as can be produced as the system is brought to thermal mechanical and chemical equilibrium with its environment through reversible processes [1]. Unlike energy, exergy is not a conserved quantity and can be destroyed during the process due to irreversibility. Rakopoulos and Giakoumis [1], Caton J.A. [2], Som and Datta [3] studie...

How To Listen To Music, Not Just Hear It Essay example -- essays resea

How to Listen to Music, Not Just Hear it   Ã‚  Ã‚  Ã‚  Ã‚  To learn to listen to music, not just hear itYou need the right room, the right equipment, the perfect volume, the perfect spot, and (of course), the embracing of the music. After you have all the proper tools, you can sit and enjoy the music. The first consideration is to listen to music in a comfortable chair. I would highly recommend a good quality Lazy Boy recliner. Now, you need to find the best room to put that chair in, so you can listen to you music. The room can be any normal room with four walls but, the room can't be wide open. For example, it can't be an unfinished basement with concrete walls and a cement floor. The sound will not be able to bounce off the walls and give the effect as if the sound is coming from behind you, as well as in front of you (the surround effect). A good room to listen in, is a typical family room with sheet rock walls and four ninety degree corners. The second consideration is placement of speakers. The corners of a room are the perfect spot for your speakers. You shouldn't position them flush against the wall, but put the back of the speaker into the corner, so each side of the speaker is against each wall. For this reason, the bass is extended (louder), and the tweeters, mid-range, and woofers give you their undivided attention. Where to sit is simple, but it takes some easy calculations to find the perfect spot. There is a common rule for a person to experience...

American Airlines and US Airway’s Merger Essay

Abstract American Airlines has suffered tremendous profit losses over the last few years. The losses have been so great that the company filed Chapter 11 bankruptcy. The news for the Chapter 11 bankruptcy protection was a shock to many, considering the fact that they had enough money to operate and cover their losses through the following year. The merger indeed was great decision on behalf of American Airlines. The merger itself was questionable. The Department of Justice filed a lawsuit against regarding concerns that it could raise prices for consumers. A settlement was reached and the world largest airline has been formed. American Airlines has been suffering for many years. The company has suffered more losses than profits. Jobs have been cut; benefits have been scaled back, and the pilots of American Airlines are paid a lot lower salaries than their competitors. Many of them have been furloughed. All of these and many other factors have contributed to American deciding to create the world largest airlines with US Airways. In this essay I will discuss the circumstances that resulted in the merger, assess the significant positive (or negative) effects of the merger, and examine the organizational structure that has resulted from the merger. American Airlines filed for bankruptcy in November 2011. According to an interview with Richard Quest of CNN, Thomas Horton the new CEO of American Airlines stated that the company was forced into bankruptcy because of the cost disadvantages it faced compared to it’s competitors that had already gone through a bankruptcy. The news came as a shock to many. The company had enough money  to sustain the losses that it may incur through the next year. Although the company had the money to operate, the company still decided to go through with filing for bankruptcy (Isidore & Ellis, 2011). At one time American was the world largest carrier, it had dropped to third in the recent years. The company has reported only one quarter where a profit was made since 2007, and lost 4.8 billion over those three and a half years. The company was projected to continue to suffer losses. Now that the merger has been approved, American will be able to get themselves out of their Chapter 11 bankruptcy protection (Isidore & Ellis, 2011). Now that the merger is complete, the new American Airlines has ordered over 600 new aircrafts that are updated and more modern. The new aircrafts will allow them to compete with their competitors. In the past they have lost a great deal of money from their business class travelers due to their lack of the amenities that their competitors carry on their aircrafts (American, US Airways reach merger deal., 2013). The two joining airlines will offer over 6,700 daily flights to 336 destinations in 56 countries. The merger will not distress any of the hubs presently served by American Airlines and US Airways. American Airlines has been in bankruptcy for a little over a year, and the merger will be effected pursuant to a plan of reorganization under Chapter 11. â€Å"The combination of American and US Airways brings together two highly complementary networks with access to the best destinations around the globe and gives us a strong platform to provide our customers the most connected, comfortable travel experience available,† Horton said â€Å"The operational and financial strength of the combined airline is expected to enable continued investment in new products and technologies and will create exciting new opportunities for our people, even as we deliver strong cash flow and sustainable profitability.† (American, US Airways reach merger deal., 2013). The merger with Us Airways allowed American Airlines to come out of the Chapter 11 bankruptcy in December. Being able to do so was the first time that a major airline has been able to satisfy a bankruptcy with a return on equity for its shareholders. By deciding to partner with a smaller, but stable US Airways, the company was able to raise the value of the combine stock. Pursuant to the plan of reorganization, so-called double-dip, single-dip, and intercompany claims were settled through a delivery process which distributed the proceeds of America Airlines’ estate based on the  trading price of the new company’s common shares. This quick fix solution lessens the opportunity of appraisal disputes by guaranteeing creditors got a current market value. When it was all said and done, American Airlines creditors, including its unsecured creditors were given payment in full. For the first time in a major airline reformation, shareholders were able to accept a return on their equity. The approved stock exchange merger left American Airlines shareholders with 72% of the new company and the US Airway investors with the lingering 28%.US Airways decided to do what most company who are going through a merger wouldn’t. They negotiated with American Airlines unions before finalizing the merger. This established a foundation of a cooperative negotiating agreement for the new company, so that labor disagreements would not disrupt or lengthen the merger development. Following numerous noteworthy airline merges it was predictable that the formation of one of the world’s largest carriers would raise some anti-tr ust hurdles. The first curtailed from the US government. The airline seized a proactive tactic, agreeing to surrender some of it apertures at airports around the US, leading to court approval of the merger (Thomas, 2014). Although the two companies have merged and are legally one entity, they have both agreed to operate separately until they can integrate both systems successfully. As with any merger, both sides will suffer losses of their employees. Majority of the top leadership positions will be held by US Airways top executives in the new American Airlines. US Airways CEO Doug Parker will head the merged carrier. Of the top eight executive positions, five of those positions come from the US Airways’ side. American CEO Tom Horton will be the chairman of the board, and will continue on through until the first meeting of the new board next year. Parker will keep the executives that he is more familiar with. The new leadership team includes US Airways President Scott Kirby and others who have worked alongside Parker for several years (American and US Airways name merged airline leadership, 2013). American Airlines has suffered tremendously over the last few years. Us Airway which is a smaller company, was in a better position financially than American. Although Us Airway was more stable, they didn’t have access to many of the locations that American Airlines did. The merger was a great idea for both. American was able to get out of their Chapter 11 bankruptcy protection earlier than anticipated. They have switched over from the Star  Alliance and move to One world global alliance. The new company now has over a 100,000 employees worldwide. Nothing but positive results seems to be coming from the merger of the two. In the beginning, the merger was questionable, and the Justice Department along with six other states filed a lawsuit against the company. The reason for the lawsuit is that they were in fear of the creation of the world largest airline raising prices on travelers. The slight raise in ticket sales, fees for flight changes, check bags, would be detrimental to consumers. American Airlines and US Airways were able to settle the suit and bring everyone to ease. In summary, the merger has run smoothly thus so far and according to plan. Currently both companies are operating individually although they are legally identified as one entity. The companies are working to collaborate their systems together as well. At the point in time, they are honoring each other’s flier miles and plan. Some of them have been eliminated to coincide with the polices of the company. American Airlines decided to merge with Us Airways to regain its place as the world largest airline. The reason for the merger has been negative on American’s side, but will benefit their company in the long run. In my essay, I have attempted to explain In the circumstances that resulted in the merger, assess the significant positive (or negative) effects of the merger, and examine the organizational structure that has resulted from the merger.

Indiana Jones: Raiders of the Lost Ark Hero’s Journey Analysis Essay

Ordinary World In the first opening scene we see is Indiana Jone’s whip in his pocket. Then we see the hat from behind and that is when the die-hard Indiana Jones fans realize that they are witnessing the entrance of a great hero. The ordinary world for Indiana Jones is really not that boring at all. He is constantly hit on by many undergraduates that he teaches in his Archaeology class. A prime example being an extremely attractive undergraduate girl closes her eye lids to display the message â€Å"LOVE YOU.† The Call The call to action in this movie was when the two federal agents came to enlist the help of Indiana Jones to acquire the Ark of the Covenant. Indiana Jones informs them of the history behind the Ark and is informed that the Nazis have found Tanis the last known location of the Ark. Jones informs the federal agents that he is no expert on the subject of Ark myth, but they should be asking Abner Ravenwood. Ravenwood collected many relics of Tanis including the head piece to the Staff of Ra. The head piece is the key to finding the Well of Souls where the Ark is kept. The Refusal Indiana Jones is gung ho about embarking on his quest to find the Ark of the Covenant. Marcus Brody, the head curator of the National Museum tells Jones that is might not be a good idea to go seeking the Ark. Brody expresses his convern when he says, â€Å"Well, I mean that for nearly three thousand years man has been searching for the lost ark. It’s not something to be taken lightly. No one knows its secrets. It’s like nothing you’ve ever gone after before.† Jones tells Brody not to worry, for he does not believe in the supernatural.† Meeting the Mentor This movie has a slight twist in terms of meeting the mentor. The mentor, Abner Ravenwood is mentioned but we never get to meet him, for Jones and he had a falling out many years prior. Jones later meets up with Sollah who guides him through Egypt. Crossing the Threshold In this movie, however, Jones goes to Nepal to go see Marion, Abner Ravenwoods’ daughter, to obtain the head piece to the Staff of Ra. Accomplishing this task is not easy for Jones because a romantic encounter he had with Marion years earlier. Test Allies & Enemies Indiana Jones is greeted quite rudely when he enters through Marion’s door she says, â€Å"Always knew someday you’d come back through my door!† and then proceeds to punch him, â€Å"In the last ten years, I learned to hate you. I was a child. You knew what you were doing.† Jones finds out that his mentor is dead. He gives her money to buy the head piece, and she tells him to come back tomorrow to retrieve it. After Jones leaves the bar, agents from the German Gustapo looking for the head piece. They subdue her and threaten to burn her with a hot poker in order to torture her for information about the whereabouts the head piece. Right as they are about to start the torment Jones comes in and saves her by whipping out the hot poker out of the tormentor’s hands. The hot poker lights the curtains ablaze resulting in the head piece heating up. The head Gustapo officer grabs the medallion and burns his hands in the process. Marion then pays back the favor to Jones by shooting an assailant saving Jones’ life. She looks and turns to Jones and says, â€Å"I’m your god damned partner!† At this point a partnership has been formed and we have Jones’ first major ally in the quest to find the Ark. The Approach * They arrive in Cairo in Egypt, where they meet up with Sollah, and an old colleague of Jone’s. * Rene Belloch is running the archaeological dig in Tannis * The Germans have found the map room that Jones had mentioned before, but cannot find the location to the Well of Souls without the head piece. * Sollah acts as their guide and warns them of the dangers * â€Å"The Ark. If it is there, at Tanis, then it is something that man was not meant to disturb. * Death has always surrounded it. It is not of this earth.† – Sollah * Jones and Marian start to rekindle their relationship * They are attacked by the Nazis and Jones throws Marion in a basket to keep her safe from harm * While hiding in the basket the monkey hops on the top cover of the basket, giving her position away * Indiana Jones seeks out Marion but is unable to find her * He shoots the explosives truck and the truck explodes which leads Jones to believe that Marian is dead * He meets up with Sollah after and they come to the conclusion that they only have one side of the head piece * The Nazis are digging in the wrong place * Sollah and Jones realize they do not have much time, for they must get to the map room around 9:00am when the sun hits the map room * The sun shines through and points them to the location where they must dig * Jones goes to Balloch’s tent and finds Marion * Jones promises to come back for her after he retrieves the Ark * They find the entrance to the Well of Souls when they are ambushed by Belloch and his Nazi cohorts Supreme Ordeal Jones is locked inside with Marion in the Well of Souls. The floor is covered with snakes which makes this even more excruciating for Jones. Snakes are Jones’ worst fear and he despises them with a passion. At this point it seems as if all hope is lost, but Jones and Marion manage to escape the Well of Souls and try to flee the archeological dig site at Tannis. The Reward After a fistfight with a giant Nazi mechanic, blowing up an airplane on the airstrip, and chasing down a fleet of trucks, Jones takes back the Ark before it can be shipped to Berlin. He obtains what he was looking for all along plus he has Marion by his side, which is what he really wanted all along. The Road Back Indiana and Marion leave Cairo to escort the Ark to England on board a steam boat. The next day, their boat is breached by Belloch, and the Nazis, who once again steal the Ark and kidnap Marion. Indiana stows away on their U-boat and follows them to an isolated island where Belloch plans to test the power of the Ark before presenting it to Hitler. Indiana reveals himself and threatens to destroy the Ark with a rocket-propelled grenade launcher, but Belloch calls his bluff, knowing Jones cannot bear to eradicate an important historical artifact. The Resurrection Indiana surrenders and is tied to a post with Marion as Belloch performs a ceremonial opening of the Ark, which appears to contain nothing but sand. Belloch’s Nazi cohorts start laughing thinking they had just wasted their time. Suddenly, angels start to emerge from the Ark. Aware of the supernatural danger of looking at the opened Ark, Indiana warns Marion to close her eyes. The apparitions suddenly morph into gruesome creatures of death, and lightning bolts and burst of fire and flame begin flying out of the Ark, killing the Nazi soldiers, while Belloch and the rest of the commanding officers meet their fates as well. Return with Elixir Indiana and Brody ask about the whereabouts of the ark and are informed by the federal agents that the Ark â€Å"is someplace safe† to be studied by â€Å"top men†. The Ark is sealed in a wooden crate and stored in a giant government warehouse in Area 51 filled with countless similar crates.

INTRODUCTION TO HUMAN RESOURCE MANAGEMENT Human resource management refers to an assortment of policies used to systematize work in the employment relationship and centres on the management of work and the management of people who undertakes this work. Therefore HRM is concerned with recruitment, selection, learning and development, reward, communication, teamwork and routine management. While it is relatively easy to list activities that make up HRM, It is a subject that stimulates much debate and disagreement. The hr process is considered as important for the management of the consumer pleasure with human recourses.

Understanding the dangers of identity theft and how a company or Essay

Understanding the dangers of identity theft and how a company or individual can be protected from it - Essay Example As advancement in technology made access to information easier, many unscrupulous people take advantage of their skills and steal sensitive information from companies and private persons online. According to the Identity Theft Resource Center, a non-profit organization based in the United States (www.idtheftcenter.org), in 2010, there were about 662 cases if information security breaches reported in the United States but the actual number may be higher since not many people and organizations report breaches on their information security system. People whose identity have been assumed by another can suffer tremendous loses. Note that once somebody steals another person’s identity, he or she may be able to access the bank accounts and other personal information of the victim (Abagnale, 2007). As it is, there is a big possibility that the victim may lose money and assets on the process. Aside from taking money and other assets from their victims, some identity thieves use the ide ntity of their victims to commit crimes (Cullen, 2007). For instance, an identity theft can sue the identity of his or her victim in fraudulent online transactions so when the fraud is reported to the police, the police go after the identity theft victim. As it is, it is very important that individuals and organizations understand the kind of risks that they are in and do something to protect themselves from identity thieves. II. Ways and Means Employed by Identity Thieves to Gain Access to Important Information There are a number of ways to commit identity theft but the most common are social engineering, phishing and hacking attempts. Social engineering is committed by exploiting human psychology to gain entry to databases, computer systems and even buildings with sophisticated security system (Hadnagy, 2010). Note that instead of attacking the software or system used by a company or individual, the identity theft uses mind tricks to retrieve sensitive information for the people i nside the building and the people who are running the databank or the system (Hadnagy, 2010). To get the information that he or she needs to gain access into the building or the database, the identity does a lot of research and identify the key persons who he or she will retrieve the needed information (Wilhelm, 2010). For instance, if the identity theft wants to gain access to a database, he or she may pose as a computer technician or IT support person and trick an employee in the IT division to divulge passwords and codes to gain access into the system. Although the basic principles of trickery used in social engineering may sound simple, the execution of the act requires careful planning and psychological manipulation skills (Mitnick, 2003; Allsopp, 2009). When planning its strategies to defraud his or her victim, the identity needs to gather all the necessary information to trick the victim. To do this, he or she may access the personal information of the person targeted using e xisting social networks such as facebook, linked in and others (Mitnick, 2003; Wilhelm, 2010). Note that a good number of users of these online networking sites tend to give out personal information such as e-mail addresses and even telephone numbers online which may them relatively easy preys for identity thieves (Wilhelm, 2010). From the information gathered from these social networking sites, the identity may now be able to psychologically manipulate the victim into giving him or her sensitive information. In most cases, the deception happens online or through the phone so the identity theft and his or her victims do not actually come face to face (Allsopp, 2009). Aside from social engineering, phishing is also commonly used by identity thieves to steal information from their victims. To steal information from their victims, identity theft pretends to be a reliable online entity such as a bank, a well known courier, website and the like (Abagnale, 2007).

Leadership - Essay Example I quickly recognized that opening up these sales channels would gain product exposure and substantial revenue growth for the company and thus made appointments with department store buyers to present our product lines. However, our President of Sales discouraged me from pursuing department stores and told me to focus on our current sales channels because it was too late in the season to change our designs and our production level was close to maximum capacity. Not one to be easily discouraged, I approached our Chief Operation Officer and Chief Financial Officer and presented my idea of special productions: uniquely designed and specially allotted productions for the department stores. They liked the idea and assigned me to head the project. I contacted the department stores’ senior buyer groups and marketing teams and worked with the production department to establish new production channels. I also worked with our design department to create exciting designs for our buyers. T he special production was further streamlined when I aggregated the department store’s marketing department with our own to create campaigns to strategically promote our products.
