Wireless LAN technology has become the actual standard for wireless Internet access, with increasing availability of access points for those wireless networks as a result of what they offer of high data rates, low roaming costs, and good in-building coverage. This led to a strong trend to the inclusion of Wi-Fi embedded sub-system in all kinds of devices included computing side, and embedded side.The smartphones with the adoption of Wi-Fi technology had to meet two requirements: 1- quality of service support for prioritizing real-time applications. 2- inclusion of power saving functionality to achieve an operating time meets the expectations of users. This paper presents a new power management technique P-PSM, it is a combination of medium access mechanism depends on Contention Window to provide the quality of service, with standard power management technology stdPSM. In addition to evaluate its performance against a set of power management techniques under changing the number of network nodes in order to clarify the expected quantity differences in terms of both quality of service and power saving.

This research aims to study the effects of weaknesses on the performance of the existing network such as the impact of Attenuation and crosstalk on the data transfer, and it presents also the improvements of the standards of DSL systems to achieve th e maximum transition rates in order to have greater speed in the installation of high-speed subscriber lines. It also offers a new range of services to communication companies through the provision of new xDSL technologies in the near future. Thus, it enables its customers access to broadband services and provides tips for the Syrian Telecommunications Company in their choice of systems. This research analyses the essence of the techniques and the strengths and weaknesses of the criteria for All Digital Mode digital subscriber line mentioned in Annex A and for higher upstream digital subscriber line mentioned in Annex M. It also includes an analytical study of the damping and crosstalk to show how to consider any criteria as a better choice. Finally, It includes programmatically represented simulation of the signal which is sent over transmission lines under the influence of the studied factors.
Batteries are energy storage devices that are particularly useful for powering small portable devices like phones, laptops and entertainment devices as well as mobility devices that travel over the earth's surface, through water and air. During the night, or during a period of low solar irradiation, energy is supplied to the load from the battery in solar electrical Power Systems, and that provides Continuity of power supply, and on the other hand boosts the Reliability of the system.
Recommendation systems are the systems thathelp users to select suitable items from a large collection of items based on their tastes and interests. Such systems have become one of the most powerful tools in electronic commerce and social websites . Nonetheless , using these systems in e-commerce websites faces many drawbacks such as: cold start-up, scalability and sparsity. In this paper, we present a solution to cold-start-up problem, and compare between many association rule algorithms to select the most suitable one to solve the scalability and sparsity problems.
This paper presents a method for finding online adaptive optimal controllers for continuous-time linear systems without knowing the system dynamical matrices. The proposed method employs one of Intelligent Operations Research Techniques, this tech nique is the adaptive dynamic programming, to iteratively solve the algebraic Riccati equation using the online information of state and input, without requiring the a priori knowledge of the system dynamics. In addition, all iterations can be conducted by using repeatedly the same state and input information on some fixed time intervals. A practical online algorithm is developed in this paper, and is applied to the controller design for a turbocharged diesel engine with exhaust gas recirculation.
A Vehicular Ad-hoc Network (VANET) is a collection of nodes forming a wireless network, but the nodes of this network are vehicles with special equipment that enable them to communicate with each other. VANET protocols have to face high challenges due to dynamically changing topologies, link breakage and low vehicular density. A suitable and effective routing protocol helps to ensure that messages are reached to their destinations and achieve the desired aim of the application. In this research, we present an analysis of the performance of two major routing protocols used in these networks, which are AODV (Ad hoc On-Demand Distance Vector) and GPSR (Greedy Perimeter Stateless Routing). This analysis is based on various parameters such as end-to-end delay and average dropped packets, in order to find the best protocol which can be used in the network with low density at the junctions. To achieve this purpose, we used a simulator OPNET_17.5. Depending on the simulation results, we have obtained and the analysis and comparison of two protocols at different low density contract. We found that GPSR protocol has better performance end-to-end delay and average dropped packets are used as the performance metrics, and is better for VANET under the low vehicular density simulation scenario at junctions.
