History of Long Term Evolution (LTE) The Third Generation Partnership Project (3GPP) started on the work of Evolution of 3G Mobile System at RAN Evolution Work Shop on November 2004 in Toronto‚ Canada. They opened a work shop to all interested organization and interested parties. Proposals on evolution of Universal Terrestrial Radio Access Network (UTRAN) were presented there. High level requirements such as reduced cost per bid‚ flexibility of existing and new frequency bands‚ simplified architecture

a music note from sine waves. For the third part‚ we do a sound cancellation experiment. We will understand the importance of phase in sounds by considering the amplitude. The concepts we will used in this experiment are followed: Fourier theorem: any periodic oscillation curve‚ with frequency f‚ can be broken up or analysed ‚ into a set of simple sine curves with frequencies f‚ 2f‚ 3f‚ 4f‚ 5f… etc‚ each with its own amplitude. Conversely‚ adding together the set of sine curves will

compute an answer‚ or when you have a math "formula" to work on but don’t know how to "process" it. Matlab allows symbolic operations several areas including: * Calculus * Linear Algebra * Algebraic and Differential Equations * Transforms (Fourier‚ Laplace‚ etc) The key function in Matlab to create a symbolic representation of data is: sym() or syms if you have multiple symbols to make. Below is an example of creating some symbolic fractions and square roots:

Race Car Aerodynamics Gregor Seljak April 8‚ 2008 1 Introduction First racing cars were primarily designed to achieve high top speeds and the main goal was to minimize the air drag. But at high speeds‚ cars developed lift forces‚ which affected their stability. In order to improve their stability and handling‚ engineers mounted inverted wings profiles1 generating negative lift. First such cars were Opel’s rocket powered RAK1 and RAK2 in 1928. However‚ in Formula‚ wings were not used

Abstact To create a continuous competitive market and deliver more services via mobile broadband to customers‚ the Third Generation Partnership Project (3GPP) developed an evolved 3G technology called LTE which tends towards the 4G technology. This work highlights the overview of LTE as well as the expectation which the technology is expected to meet which attributes its advantages. Being the first true IP-Packet technology with new architecture‚ the network architecture evolution is also discussed

Literature Review This paper draws literature that discusses stress and time management in relation to leadership skills that subscribes to an embodied view of organisations. In Forsyth (2003)‚ time management is about working actively to create efficiency and effectiveness in a way that makes achieving your target more likely. Good effective time management is a core skill‚ a differentiating factor which allows you to have an edge over other people (Williams & Cooper 2002). Time management

Abstract— This thesis will analyze several similarity measures in a dental identification context. This identification will be based on a 3D scan of a patient’s skull and 2D radiographic images taken respectively post- and ante-mortem. This approach allows to circumvent the variable projection direction and/or incorrect patient positioning when capturing the classic 2D bitewing and periapical images. Three classes of experiments can be distinguished in this paper. First‚ there are the registrations
