...that was stolen from federal funds through a ring of crooked public officials and government contractors in the D.C area that used kickbacks and bribery in the scheme. The FBI called the partners of the fraud the 5 aces because that term is used in reference to someone stacking the deck in a card game so they can cheat. The master mind of the fraud was Kerry Khan and there were a total of 15 federal employees and contractors and several companies involved. Some of the people involved in the fraud was Michael L Alexander, former program manager, Lee A. Khan, son of Kerry Khan, Harold F. Babb, former director of contracts at Eyak Technology LLC (Alaska Native-owned small business), Alex N Cho, the former chief technology officer of Nov a Datacom LLC, and Mckinny, the president of Alpha Technology Group Inc., (a provider of program management services). The fraud was committed within the US Army Corps of Engineers where Kerry Khan was employed. The U.S Army Corps has the guiding principle of environmental sustainably and that task is done with approximately 37,000 dedicated civilians and soldiers providing engineering services to customers in more than 130 countries. The Corps works diligently to strengthen our Nation’s security by building and maintaining America’s infrastructure and developing technology to help fight wars. They also provide valuable service in America by dredging the waterways to keep trade going and they have a part in...

...Introduction Novopay a new IT school payroll processing programme was introduced by the Ministry of Education (MOE) New Zealand on 20 August 2012 to upgrade the old payroll system. It was implemented to around 110,000 MOE employees which included teachers and support staff both at state and state-integrated schools throughout the country. This replacement process had been in development since 2003. Unfortunately Novopay has been plagued with ongoing problems from the outset resulting in over-payment, underpayment and non-payment of a significant portion of MOE staff as well as ongoing inaccuracies with the payroll system. Nearly three quarters of New Zealand schools have been adversely affected. The New Zealand Principal’s Federation president Paul Drummond stated “We are trying to do the impossible in an environment that is intolerable with a system that is dysfunctional . . . it is simply unprofessional and unacceptable” ( ). Eight months after the implementation of Novopay an investigation was undertaken by the New Zealand government to address fixing over 8,000 glitches in the system. Causes of the failure of this system have been numerous throughout the design, implementation and oversight stages of the project. The breakdowns within many layers of the working relationships for example between the Ministry and Talent 2 and the Ministry and the schools that were critical for the success of this project are outlined in the Ministerial Inquiry undertaken...

...in the company. They never heard of news of people getting promoted due to the lack of transparency in the company which eventually led to low motivation. After implementing the intranet promotion announcement system and having award ceremonies, staff became more aware of these promotions and realize that it was possible to achieve their intrinsic and extrinsic goals. This in turn resulted in an improvement in the organizations performance as staff began to work harder. Like SRO, focus groups were set up at Deloiite as well but with a different agenda. They were organized to learn from the culturally diverse workforce in the company so as to set up an initiative to attract and retain talented employees. In another case, the company Datacom learnt that the level of engagement from workers varied between teams. Even though members of the team were happy, their performance levels still weren't up to standard. Teams who were happy with their work environment and were well engaged in their projects were the most productive. This was due to the relationship between staff and managers. Whenever a team had a manager who made the effort to build genuine relationships with his/her staff, the team performed better as the manager displayed trust and empowered his/her staff by giving them more responsibilities. Workers then become more engaged in their work . With such...

Inverted Index File Systems: It is an index data structure that stores a mapping from any given content, i.e. words or numbers, to their respective locations in a database file. Its purpose is to allow fast and full text search, at increased processing cost when a document is added to the current database. Several mainframe-based database management systems have used inverted index architectures like ADABAS (Adaptable Data Base System), DATACOM/DB, and Model 204. Object-Oriented Databases: The term "object-oriented database" or OODBMs first appeared in 1985 after the notable research projects that included notable names like Encore-Ob, EXODUS, IRIS, ORION and Zeitgeist. These databases store objects rather than data i.e. integers, strings or real numbers. These databases can store deep hierarchies of objects and complex data types by classifying objects for random information. These databases are designed to work efficiently with OOP (Object-Oriented Programming Languages) such as Delphi, Ruby, Python, Perl, Java, C#, Visual Basic .NET, C++, Objective-C and Smalltalk. Comparison of OODBMs with RDBMS: As far as data modeling is concerned, OODBMS deals with objects while RDBMS...

...Financial Frauds in India The 2G scam Aniruddh Narsimhan - P35114 Disha - P35125 Manu Vatayan – P35149 Mrinalini - P35152 Svethal Bhasin - P35188 2G spectrum scam took place in India in late 2000’s which involved politicians and government officials who tried illegal undercharging mobile telephone companies for frequency allocation licenses, which they would then use to create 2G spectrum subscriptions for mobiles. The entire process of allocation of UAS licences lacked transparency and was undertaken in an arbitrary, unfair and inequitable manner. The Hon'ble Prime Minister had stressed on the need for a fair and transparent allocation of spectrum. Let us understand the intricacies of the scam. What is Spectrum? Radio Frequency Spectrum is the entire range of wavelengths of electromagnetic radiation which is used as carrier of wireless transmission and thus a basic requirement for providing wireless services. It is a finite but non-consumable global natural resource and commands high economic value in the telecommunication sector In simple words , Whenever data is being transferred from one place to another, say Ahmedabad to Mumbai. So, If data was a “truck”, how would you transport it from Ahmedabad to Mumbai ? Obviously through a path. Spectrum is that path. Radio frequency spectrum, i.e., the entire range of wavelengths of electromagnetic radiation, is a finite global natural resource with a high economic value, due to its heavy demand in the telecommunications...

...APPLICATION NOTE 183 RFC 2544: HOW IT HELPS QUALIFY A CARRIER ETHERNET NETWORK Bruno Giguère, Member of Technical Staff, Transport and Datacom Business Unit Service providers worldwide are actively turning up new services based on carrier Ethernet technology in a fierce competition to attract premium subscribers. The need for quality services has never been more important, making comprehensive Ethernet testing immediately at service turn-up vital to ensuring service quality and increasing customer satisfaction. Customer service-level agreements (SLAs) dictate certain performance criteria that must be met, with the majority documenting network availability and mean-time-to-repair values which are easily verified. However, Ethernet performance criteria are more difficult to prove, and demonstrating performance availability, transmission delay, link burstability and service integrity cannot be accomplished accurately by a mere PING command alone. Portable RFC 2544 test equipment enables field technicians, installers and contractors to immediately capture test results and demonstrate that the Ethernet service meets the customer SLA. These tests can also serve as a performance baseline for future reference. What is RFC 2544? The RFC 2544 standard, established by the Internet Engineering Task Force (IETF) standards body, is the de facto methodology that outlines the tests required to measure and prove performance criteria for carrier Ethernet networks. The standard provides...

Unitech Infrastructure and Unitech Builders & Estates were already subsidiaries of Unitech Group. So in 2008 Unitech had 22 2G licenses. Later in the same year Norway based company Telenor bought majority stake in the telecom company from the Unitech Group. Now it offers services under Uninor brand holding 22 pan India licences. * Operates under brand name Videocon Telecommunications Limited- 21 2G licenses * Loop telecom-21 2G licenses * Shyam Telelink Limited & Shyani Telelink Limited operate together with their combined 21 licenses. During late 2008 Russia based group Sistema bought majority stake in the telecom company and now they operate under brand name MTS India * In 2008, Swan Telecom (15 2g licence) merged itself with Allianz Infratech (P) Ltd. During late 2008 Abu Dhabi's Etisalat bought about 45 percent of the company and renamed it to Etisalat DB Telecom. * Idea Cellular bought Spice Communications Ltd. in 2008 for an amount of 2,700 crore (US$488.7 million). So out of 122 spectrum licenses sold in 2008 Idea Cellular owns 13 licenses. However of the 13 licenses, only 7 of the licenses are in use by the company and the rest are overlapping licenses. * In January 2009, Bahrain Telecommunications signed a deal with S Tel to buy 49% shares in S Tel for $225 million.
