...Delta encoding Delta encoding is a way of storing or transmitting data in the form of differences between sequential data rather than complete files; more generally this is known as data differencing. Delta encoding is sometimes called delta compression, particularly where archival histories of changes are required (e.g., in software projects). The differences are recorded in discrete files called "deltas" or "diffs", after the Unix file comparison utility, diff. Because changes are often small – for example, changing a few words in a large document, or changing a few records in a large table – delta encoding greatly reduces data redundancy. Collections of unique deltas are substantially more space-efficient than their non-encoded equivalents. From a logical point of view the difference between two data values is the information required to obtain one value from the other – see relative entropy. The difference between identical values (under some equivalence) is often called 0 or the neutral element. A good delta should be minimal, or ambiguous unless one element of a pair is present. Simple example Perhaps the simplest example is storing values of bytes as differences (deltas) between sequential values, rather than the values themselves. So, instead of 2, 4, 6, 9, 7, we would store 2, 2, 2, 3, −2. This is not very useful when used alone, but it can help further compression of data in which sequential values occur often. IFF 8SVX sound format applies this encoding to raw...

...CASE STUDY: Delta Airlines Inc. by Benjamin Godman Delta Air Lines is a major American airline and one of the world’s largest air carriers by traffic serving over 330 destinations in over 60 countries on six continents. Originally starting out operating crop dusters and delivery mail in Louisiana, Delta now utilizes over 700 aircraft and subsequent support activities like maintenance and operations. Delta airlines services over 165 million customers worldwide every year by averaging over 5000 flights daily. Delta Air Lines is now the oldest airline operating in the United States and is the result of multitude of airline mergers over the past 80 years that included Pan American World Airways and Western Airlines just to name a few. Its most recent merger with Northwest Airlines in 2010 was its largest in its history and in 2013 finished with $5.7 billion in unrestricted liquidity, generated $4.5 billion in cash from operating activities, reduced debt by $1.4 billion and funded capital expenditures of $2.6 billion and returned $350 million to shareholders. Delta’s 2013 pre-tax profits were up 147% in comparison with 2012. In recent years, Delta was a founding member of the Sky Team Alliance, created Delta One which is an Elite business cabin, introduced flatbed seats for international travel, Delta Comfort+ for increased comfort in the main cabin seating and other amenities to ensure its competitiveness with other airlines such as American Airlines Group Inc., Southwest...

...Delta Airlines Cynthia Howard-Morgan BUS499 Professor Anderson July 29, 2012 Introduction The longest-running airline carrier, Delta Airlines began in 1924 as a crop-dusting company called Huff Deland Dusters. Delta has since become a world leader in providing efficient, on-time travel, since 1941, the company has been based in Atlanta, where Hartsfield-Jackson International Airport serves as its largest domestic hub and primary base for flights to over 57 countries. The airline also operates four other hubs in major U.S. notably Los Angeles which it has recently reestablished (Delta, 2011). Due to competition from lost-cost airlines, the negative effects of 911 on travel and skyrocketing fuel prices, the company held over $20 billion in debt as of September 2005 Delta declared bankruptcy. Delta was able to emerge from bankruptcy in 2007, achieving profitability that same year. In April, 2008, Delta announced its intention to purchase Northwest Airlines. The two companies combined created the world’s largest airline. Currently it is the only airline to service all six permanently inhabited continents in the world. The company's structure and management approach have constantly evolved in order to maintain competitive in the cutthroat airline industry (Delta, 2011). Delta vision will able them continue to be the world’s largest and the world’s greatest airline. Segments of General Environment Segments that rank the highest would be suppliers and work...

...(Cite p. 258). By writing and sending out the internal memorandum the CEO Richard Anderson displayed exceptional management communication skills, because the information was sent to the right stakeholders which were the employees of Delta Air lines, this communication or information was not meant for other stakeholders such as the customers of Delta or the employees of Northwest Airlines. This communication was also sent out at the right time, a day before the media got the news ensuring that the employees do not hear the news of the final merger agreement from an outside media source. The internal memorandum sent out within Delta Air lines gave the employees an idea of the change going on in the company and how they would be affected. In communicating change, the reasons for the change, and the benefits of the change should be stated. These areas were all communicated through the internal memorandum. Reading the internal memorandum one can see that the voice of the memo tries to connect with the readers. The style, tone, voice, and word choices Delta CEO Richard Anderson used in the memo effectively communicated the change. The memo listed out what has been changed hierarchically, who the new CEO and CFO would be due to the merger of both Delta and Northwest Airlines and what has been changed, talking about the physical office location, and also how this change would benefit his employees and the employees of Northwest airlines (Cite)...

...A03-04-0011 Delta Air Lines: The Latin America Contact Center Decision PY In early September 2000, Mary Smith, Delta Air Lines’ Regional Director of Reservations for Latin America and the Caribbean, glanced over her notes one more time. Delta had decided to consolidate all of its reservations offices in Latin America into a single Latin America Contact Center. Now it was up to her to recommend a country location for this $3–4 million investment. Gail Childs, her immediate supervisor and General Manager for International Reservations, would want her report soon in order to get the final go-ahead from Delta’s CEO. Although a number of countries were possible options, Mary reviewed again the pros and cons for Mexico, Chile, and Argentina. CO The Internationalization of Customer Service NO T By 2000, telephone customer service was growing rapidly throughout the world. Many companies chose to outsource their telephone customer service operations to outside call centers; others kept such operations in-house. Other than locating call centers, also known as contact centers, within a region to be closer to customers, the principal reason for U.S. companies to move telephone customer service outside of the United States was to reduce costs. Because labor costs constituted between 60–80% of a call center’s operating expenses,1 airlines, computer firms, credit card companies, and others that used telephone customer service extensively were moving these...

...Delta Song Case Executive Summary U.S. Airlines face many issues today that ultimately will lower profits. Heightened Security in airports, less people willing to fly and a slumping economy have put the airline industry at a disadvantage. Delta Airlines has reported recently a $2 billon dollar second quarter loss. Delta has been losing ground to smaller airlines that fly the same routes that supply Delta with approximately 70% of its revenue. Delta Airlines will attempt to become the first major carrier to successfully launch a long term, low cost competitor. In the past year alone, low-cost carriers such as Jet Blue have claimed over 80% of the market share in New York to Florida flights. The new airline will be call Delta Song, and will cost $75 million The Delta Song Concept will use only one type of plane, the Boeing 757, that will be outfitted with leather seats, interactive monitors that will allow users to watch pay per view movies, play interactive games and online shopping. Song flights will fly between selected cities. Song planes will feature faster turnaround times of 50 minutes between landing and take off. Flight time is expected to be approximately 13 hours a day, which is 23% higher than the Delta main line. The goal of Delta Song is to compete with smaller airlines that will push Delta away from chapter 11 and return to profitability and future success. Analysis Delta will need to shift ticket sales operations away from...

...Question 1 (i) Delta Air Lines need to update the residual value and depreciation of their aircraft over time in order to calculate the life of the aircraft. The calculation requires estimation and assumptions such as the long-term of usage, maintenance cost, residual value and economic conditions which need constant review. Technological changes in the industry are one of the reasons why Delta Air Lines decided to extend the useful lives of their flight equipment. Technological advances such as changing engines from pistons to jet engines allow aircrafts to function more efficiently with less wear and tear on the airframes and for longer period of times. With consistently updated with latest technology, aircraft are better maintained and can simply last much longer. In addition, Delta Air Lines decision to change in depreciation since 1986 had a positive impact on the company’s financial statements. Depreciation is a non-cash item which does not affect cash flows or revenue. However, it does have an effect on the net income. By stretching out depreciation, Delta will see a decrease in depreciation expense resulting in higher net income. This is crucial for not only for Delta Air Lines, but to all airlines companies as well as intense competition and deregulation in the industry were being pressured to show more profits and results. The disadvantage to decreasing in depreciation is taxes. With decreased depreciation and increased net income, Delta Air Lines’ income...

...Delta Airlines and the Trainer Refinery American Public University Strategic Management 05 July 2015 By Jon Kaercher Abstract The airline industry is a highly competitive service industry that operates on thin profit margins the airlines have to be flexible and adjust quickly to changes in customer’s preferences, increased fuel costs, and changes in the economy that can have a direct impact on profitability. The airlines look for solutions such as adding services, offering discounted ticket pricing and receiving subsides from the government to ensure they remain solvent This requires each airline constantly monitor its business strategy to ensure that it exploits every opportunity to provide their customers with the best possible flying experience. 1) What drive the basic economies of the airline industry? The refining industry. The airline industry operates as a service industry in which it provides the transportation of its customers and their personal belonging from one destination to another for a fee. To provide this service the airlines require a large amount of capital to purchase and maintain expensive equipment and facilities. Their cash flow is generated from profits and the depreciation of their airplanes, this cash flow is used to repay debts and buy new aircraft. The airline industry is very labor intensive because it’s in the service industry and its customers require personal attention, this can be very expensive for the airline. Over one...

...Delta Air Lines INC is a major United States airline that services both domestic and international travel. Delta is part of the “big four” legacy airline carriers, contributing to approximately 15.1% of the US domestic airline market share. Delta and its subsidiaries offer flights to 341 destinations with over 13,000 flights daily. Established in 1924, agricultural scientist Collet Woolman founded Delta as a crop dusting service. A few years later, the crop dusting service broke away and formed Delta Air Service. As time passed, Delta successfully expanded through technological innovations, research and development, and acquisitions with alliances. Product quality, consumer relations, and product safety are all key components to a successful airline carrier. In the past, Delta has demonstrated strong customer safety initiatives, thus contributing to their success. In contrary, Delta has been faced complainants from customers related to lost luggage, poor performance, and poor operations. Merging airlines is often complex can sometimes backfire. Much of Deltas growth in the last 10 years is attributed to the Northwest Airlines acquisition in 2008. When the two airlines merged, revenue increased and net income grew substantially, despite other costly economic factors. In order to successfully execute this merge, the management executives at Delta carefully planned the various stages of this risky move. Before merging, Delta faced issues with customer service, labor...

Woolman, an agriculture extension agent (Anthony, Kacmar, & Perrewe, 2010). C.E Woolman was not a banker, venture capitalist or war pilot, as many of the competing airlines were. He didn’t have the aggressive military style that many of the other airline founders had. What C.E. Woolman instilled within the employees at all levels of the organization is that people matter and should be treated fairly and equitably. This philosophy led Delta Airlines to be the leader in customer service from the company’s inception through the many mergers over the years. Through the difficult financial times when other airlines were laying off employees and filing for bankruptcy, Delta continued to pay their people well and keep them employed. There was an exception during the Ronald Allen CEO era of 1987 thru 1997. Human relations took a significant down turn during his tenure as CEO, especially during 1993 and 1994, but Delta decided to part ways with Allen and began repairing...

...OVERVIEW OF THE CASE In 2002 Delta airlines faced the unfortunate realization that the competition from low cost carriers like Southwest and JetBlue was becoming a serious problem. Even though Delta had been looking at this problem for a long period of time, the business model of Delta Airlines was organized by function and their solutions generally focused on individual aspects of the firm. For example, the marketing department provided marketing ideas, the customer service department offered customer related solutions etc. Delta realized that they did not have a comprehensive solution to dealing with the low cost carriers in the market. One of the simplest solutions proposed by Delta management was the idea that Delta could launch its own low cost subsidiary, however, looking at the rest of the airline industry, low cost subsidiaries seemed to be ideas that were either immediate failures or unsustainable over time. According to experts, they had “never seen a high-cost carrier transform itself into a low cost carrier”. With or without this option, Delta would have to find a solution to this problem. The airline industry in the United States is immense, with more than 620 million passengers and over $81 billion in fares in 2001 alone. Unfortunately, while immense in size, in terms of profit, the airline industry continued to perform below the average for other industries. Many investments made by the larger carriers were not profitable and the tragedy of 9/11 put more pressure...

In 2008 merged with Northwest Airlines, become the largest airline in the world. In May 1st 2007, Delta adopted policies regarding estimated lives & residual values for aircraft, but its was far from the 1st time it had changed its estimates. PPE (flight, ground property) are often more than half of the total asset. Depreciation of those asset is a major operating expenses and is not an attempt to measure the current value of assets. The amount of depreciation estimated by an airline company for each operating period is based in the cost of asset, estimates of asset lives, and assumptions about residual values at the end of the asset lives. These estimates & assumptions have changed through the years for almost all airlines. Depreciation practices had been change several time. CAUSE AND STATEMTN OF PROBLEM Delta, has changed assumptions of economic life of aircraft 4 times since 1986, each time extending the expected life by 5 years...
