The objective of this study is to examine the cost implication and reactive power generating potential of the synchronous condenser. Universally, increase in electricity demand constitutes new issues for power generation, transmission and distribution. Synchronous condenser solutions are being initiated globally to be instrumental in the best usage of power resources and offer grid systems support for todays and future sustainable, stable and reliable electrical grid network. This research x-rays the cost implication of the synchronous condenser in today's challenging environment. A vivid description of the reactive power generating potential of the synchronous condenser is shown with Matlab/Simulink environment simulation of a medium voltage (MV) power system network. It is observed that the synchronous condenser is cost-effective as compared to other reactive power generating equipment's and sources. Furthermore, Matlab/Simulink simulation results of the MV electric-power network shows an effective scheme for reactive power generation.

In this study, we design a dual cooperative camera system to maintain the both requirements of a visual surveillance system of tracking and close-up viewing functions in real time. In most of the object tracking or detecting systems, the details or close-up views of the objects are easily neglected for surveilling the environment to keep the camera in wide field view. Besides, some of the systems use the master-slave mode to keep one camera always in a close-up mode and the other camera in searching mode, and it may cause the dead end problem in surveillance or miss the target for not allowing the dynamic change of the roles of both cameras. Therefore, the cooperative dual camera system can not only extract the object correctly by analyzing the human body's shape but also predict the moving position and height of the human to have a close-up view. The dual pan-tilt-zoom (PTZ) cameras are used in the system to have the adjustable zooming and focusing parameters. The experiment results demonstrate that the proposed algorithm can obtain clear close-up views for either a single target or multiple objects in real time.

Software-Defined Networking (SDN) consists of two planes: the control and the forwarding plane. The control plane is moved out of the switch and into the separate, centralized controller, and is responsible for configuring the switch and programming the paths to be used by data flows. The controller hosting the applications collects information from the OpenFlow switch using the OpenFlow protocol and manipulates the forwarding of packets. This paper is to implement a QoS/QoE mapping and adjusting application that is used by the ISP to monitor the user-perceived QoE after accessing the service. The application is implemented on the RYU controller platform to monitor the performance of the OpenvSwitch-based OpenFlow switch. The implementation results show that the designed application can directly reflect the perceived quality of users and provide the ISP with valuable information for offering higher quality services.
SDN (Software-Defined Networking)分为两个平面:控制平面和转发平面。控制平面从交换机移到独立的集中式控制器中，负责配置交换机并对数据流使用的路径进行编程。承载应用程序的控制器使用OpenFlow协议从OpenFlow交换机收集信息，并操纵数据包的转发。本文的目的是实现一个QoS/QoE映射和调整应用程序，用于ISP在访问服务后监控用户感知的QoE。该应用程序在RYU控制器平台上实现，用于监控基于openvswitch的OpenFlow交换机的性能。实施结果表明，所设计的应用程序能够直接反映用户的感知质量，为ISP提供有价值的信息，以提供更高质量的服务。

Wireless sensor networks (WSNs) show immense promise in many applications, such as environmental monitoring and remotely metering. Compressive sensing (CS) is a novel signal processing that has been envisioned as a useful regime to address the energy and scaling constraints in WSNs. CS is able to move the burden of sensory nodes to central cloud/server. However, prevailing CS reconstruction algorithms are vulnerable to noise. In this paper, we exploit the natural noise-tolerance property of least mean square (LMS) adaptive filter and propose a greedy-LMS algorithm for CS reconstruction. When SNR is 48dB, greedy-LMS algorithm achieves 16% and 47% higher successful rate than BPDN and OMP, respectively. In addition, the computational complexity of greedy-LMS is competitive with OMP.
