In this modern world, communication is the heart of the world. In future, the wireless communication systems will require the high data rate technologies as the demanding of high data rate services such as multimedia, voice etc. There are various modulation techniques that are require for transferring the data. However, for transferring large amount of data some new modulation schemes are requires. One of these new modulation technique is Orthogonal Frequency Division Multiplexing (OFDM) . Therefore, to meet this enormous demand of higher data rate and better coverage of wireless network, one approach is to increase the channel bandwidth over which the radio signal is transmitted. But this approach is not practically possible as the frequency spectrum is very expensive...

- VARIABLE LEAKY LEAST MEAN SQUARE (VLLMS) The cost function of conventional LMS  does not take care of drifting the Wn in presence of external disturbance. Therefore to overcome from this problem we have consider Leaky LMS with the cost function as Jn=e_n^2+γw_n^T w_n (9) Where γ should be choose between 0 and 1 so that to avoid drifting parameter....

- I. Introduction Sound policies are the underpinning of the democratic governance and closely related to citizens’ livelihoods, the operation of business and the interests of various social groups. Formulating sound policies is the important start of the policy making process, while the implementation system of these policies is the key to determine the outcomes of the policies. Hadson and Lowe (2004, 245) point out the significance of implementation: Policy is not a settled end product and the significance of the moment and place of delivery is that policy can be and usually is remade during implementation....

- ... But handling events like cache misses, interrupts, and branch misprediction which causes interrupts in pipelining are costly. Instruction-level parallelism: It is a technique of executing large number of instructions in each clock cycle by using out-of-order execution on the basis of instruction dependencies instead of program order. Cache hierarchies: Most frequently used data are saved in cache in order to fast access of data if it is required in future which reduces time. Currently multiple levels of cache are used....

- Projects IN Controlled Environment is the abbreviation for PRINCE2. It is one of the process based development method for efficient project management. The UK government used this method extensively but it also recognized widely and used in private sectors in the UK as well as internationally. This PRINCE2 method is within the public domain and it provides non-proprietorial support on best practice and guidance on managing the project. The PRINCE2 offer the required project governance to work in and around waterfall delivery framework.... [tags: Project management, Management, PRINCE2]

- ... Holding period return (HPR) or holding period yield (HPY) may be used to measure Historical returns 2. PROBLEM STATEMENT Investors desire an effective portfolio to invest on, with preferable high returns and low risk. Potential returns rises with an increase in risk. Low levels of risk (uncertainty) are associated with low potential returns, whereas high levels of risk (uncertainty) are associated with low potential returns. When choosing investments portfolio you must be aware of your risk tolerance.... [tags: efficient allocation, risk, return, investment]

- Abstract— Autonomous mobile robots have been employed in wide applications in human life such as industry, disasters, military, and security. Meanwhile, robot secure navigation and guidance toward targets became an attractive subject for researchers. In most recent navigation methods, both the line-of-sight angle and the relative distance between the robot and target are assumed to be available. On the other hand, some navigation algorithms are based on distance information. For example, Equiangular Navigation and Guidance (ENG) law is a range-only navigation law....

- The EHR implementation is not a simple process. It is a comprehensive process that involves a lot of practices. There are misconceptions about whether the implementation of the EHR is a project or a program. This misconception arises because of the various processes that are involved in the whole process. It is a time-consuming undertaking, and it is critical to have a deeper understanding of whether it is a project or a program. This paper lays a focus on whether the EHR is a program or a project and also the characteristics from each process such as planning, selection, and benefits realization....

- Acquisition of IT systems and implementation HIT can be a very challenging process, of which you are aware. Integrating HIT into your practice can be costly, but having unlimited resources does not take the place of careful planning. More important than the choice of hardware or system to implement is how well you and your staff work together to incorporate HIT into your practice.1 First, I’d like to discuss your first question, “what went wrong?” The problems you have experienced are common, as the process to effectively implement HIT can be complex and require adequate resources, staff, and time.2 WAGER Lorenzi and Riley identified 8 common reasons for system failures, including proble...

- Definition of Project: The implementation of the Housing Development Board (HDB) Singapore in 1960 has provided housing for nearly three million residents in Singapore. However, the organization has begun to transition their organizational culture, improve customer service quality and improve their organization 's image. These changes came about when “the government agency was striving to become much more customer focused, more efficient, and innovative in meeting the changing needs of the population it served” (Jick & Peiperl, 2011, p.430)....
