Dramatic increase in electric energy demand results the power system network to span in a large scale, consequently increasing the possibility of power disturbances, which may lead towards major blackouts. Therefore the power system stability is of prime importance and mainly influencing factors such as rotor angle stability, frequency stability and voltage stability. This paper discusses the overall power system stability improvement using series injection with a suitable control technique. The proposed control technique for series injection has been simulated using EMTDC/PSCAD software. The suitability of this controller operation was tested in three cases of (i) simple power system network (ii) standard IEEE 12 Bus system and (iii) the 220 kV Biyagama — Kotmale transmission line, the major line tripping of the Sri Lankan transmission network. Simulated results have been presented and the improvement on stability is confirmed.

Among the most dynamic and spirited businesses in the contemporary world, software (SW) industry takes the lead. Being an engineering discipline, it requires intelligence of skilled workers and the practice of complex processes. The rapid change of technologies and user requirements leave the software development companies with a great risk on a ground where many are rivals. This atmosphere is less promising to the Small and Medium Scale Software Companies (SMSCs) compared to the large companies with sound expertise, finances and well set processes. This is where Knowledge Management (KM) comes in handy to provide competitive advantage as well as sustainability for such organizations to thrive with improved productivity, quality, customer satisfaction and people friendly internal culture. This paper presents a conceptual model of KM that helps SMSCs to achieve competitive advantage.

High penetration of wind power is hindered by the variability and uncontrollability of wind power output. Many research publications already proposed solutions using energy storage devices. However due to capital and maintenance cost, real applications of energy storage are limited. Wind turbines employing wound rotor induction generators where either rotor resistance is controlled or a voltage is injected to the rotor are already in existence. This paper investigates a novel method where an external controllable impedance is added to the rotor of a wound rotor induction generator based wind turbines. Varying rotor impedance contributes to control the output power of the wind turbine, in four ways by changing (i) torque speed characteristic, (ii) power extraction from the wind, (iii) kinetic energy in the turbine inertia and (iv) electrical losses. The complete rotor impedance control was developed and studied using PSCAD/EMTDC and MATLAB simulation packages. Results confirmed that the controllability of the wind farm is increased using rotor impedance control technique. Finally a time domain study was performed in simulation and it showed that the output power of the wind farm was kept at constant while fluctuating natural wind speed input was given.

Developing a system that helps system administrators to perform their administration task more effectively and efficiently is of great importance to reduce downtime, cost and man power requirement. The Advanced Remote PC Management Suite facilitates centralized management of PC infrastructure employing the Intel Active Management Technology (AMT). This technology enables the system administrators to monitor and manage computers via a dedicated channel regardless of whether the computer is powered on. This is known as Out-of-Band (OOB) management. Currently AMT is available in Desktops and Laptops with The 2nd generation Intel Core vPro processors. Using features of AMT, the The Advanced Remote PC Management Suite provides a real-time and intelligent asset management facility in addition to monitoring and administration capabilities. The system also features automated operating system deployment and centralized disk cloning mechanisms. It is also possible to isolate any computer in the network using the system, during incidents such as virus infections. Therefore, this system is able to drastically reduce the number of desk-side-visits by system administrators to setup and troubleshoot PCs in large enterprise networks.
开发一个能够帮助系统管理员更有效地执行其管理任务的系统，对于减少停机时间、成本和人力需求非常重要。高级远程PC管理套件采用英特尔主动管理技术(AMT)，便于PC基础设施的集中管理。该技术使系统管理员能够通过专用通道监视和管理计算机，而不管计算机是否通电。这被称为带外(OOB)管理。目前，AMT可用于配备第二代英特尔酷睿vPro处理器的台式机和笔记本电脑。利用AMT的特性，the Advanced Remote PC Management Suite除了提供监控和管理功能外，还提供实时和智能的资产管理功能。该系统还具有自动化操作系统部署和集中式磁盘克隆机制。在诸如病毒感染等事件期间，也可以隔离使用该系统的网络中的任何计算机。因此，该系统能够大大减少系统管理员在大型企业网络中设置和排除pc故障时的桌面访问次数。

Recently, robotic surgical support systems have been clinically used for minimally invasive surgery, and the development of surgical support devices with the application of robot technology is in demand. We have developed a new bending technique with a screw drive mechanism so far, which allows for omnidirectional bending motion by rotating two linkages, each consisting of a right-handed screw, a universal joint and a left-handed screw. The new screw drive mechanism, termed Double-Screw-Drive (DSD) mechanism, was utilized in a multi-DOF robotic forceps manipulator for laparoscopic surgery. In this paper, the DSD mechanism is improved so that the degree of freedom of motion of the tip position is extended. In order to control bending motion of new DSD mechanism, equations which give the amount of rotations of each linkage are derived. In addition, the motion space of the tip position is analyzed using the derived equations.

Nonlinear phase noise in a fiber optical communication system with 16 Quadrature Amplitude Modulation (16-QAM) has been analyzed in this work. Three new constellation schemes are compared with the post compensation using mean shift rotation method. The new constellations focus on optimizing the ratio between the amplitudes in the 16-QAM and placing the points of 16-QAM in different patterns to minimize the effect of the nonlinear phase noise. In previous works, the best performance was achieved with circular constellation without any additional compensation techniques. The performance is improved by improved circular constellation with optimized radii, five shells circular constellation and improved five-shell circular constellation in this work. The improved five-shell circular constellation diagram improves the bit error rate performance by one order of magnitude from the existing circular constellation at the transmission distance of 3000 km. This result is due to the fact that moderate amplitude signals are more tolerance to nonlinear phase noise.

A method is proposed for automatic recognition of elephant infrasound calls. It uses Linear Predictive Coding (LPC) for extracting the formants of the elephant rumble. A novel feature extraction technique is proposed to capture the unique features of elephant rumbles. The features are then processed using a two state Hidden Markov Model (HMM) to automatically detect the presence of elephants. The method is tested on pure elephant rumbles as well as field recorded signals containing environmental noise. The results show that the proposed method can be used to successfully detect the presence of elephants even under noisy conditions.

In the state-of-the-art visual object recognition, there are a number of descriptors that have been proposed for various visual recognition tasks. But it is still difficult to decide which descriptors have more significant impact on this task. The descriptors should be distinctive and at the same time robust to changes in viewing conditions. This paper evaluates the performance of two distinctive feature descriptors, known as SIFT and extended-SURF (e-SURF) in the context of object class recognition. Local features are computed for 11 object classes from PASCAL VOC challenge 2007 dataset and clustered using K-means method. Support Vector Machines (SVM) is used in order to analyse the performance of the descriptors in recognition. By evaluating these two descriptors it can be concluded that e-SURF slightly perform better than SIFT descriptors.

External stress and design parameters of photonic crystal fiber (PCF) play significant role in controlling the propagation properties during drawing process. In this paper, we have analyzed and simulated the effect of external stress and design parameters on PCF's propagation properties for two kinds of air-hole arrangement using finite element method. The effective indices for both arrangements are observed in FEMLAB environment by varying the number of air hole rings and then birefringence, effective area and polarization mode dispersion (PMD) are calculated. It is found that under same values of external stress and various design parameter, the effect on effective area, birefringence and PMD is higher in hexagonal air-hole arranged PCF than octagonal.

The bag-of-keypoints representation started to be used as a black box providing reliable and repeatable measurements from images for a wide range of applications such as visual object recognition and texture classification. This order less bag-of-keypoints approach has the advantage of simplicity, lack of global geometry, and state-of-the-art performance in recent texture classification tasks. In such a model, the construction of a visual vocabulary plays a crucial role that not only affects the classification performance but also the construction process is very time consuming which makes it hard to apply on large datasets. This paper presents a fast approach for texture classification that integrates existing ideas to relieve the excessive time involved both in constructing a visual vocabulary and classifying unknown images using a support vector machine based decision tree. We conduct a comparative evaluation on three benchmark texture datasets: UIUCTex, Brodatz, and CUReT. Our approach achieves comparable performance to previously reported results in multi-class classification at a drastically reduced time.
