Abstract---Virtualization is a technical innovation designed to increase the level of system abstraction and enable IT users to harness ever-increasing levels of computer performance. The most fundamental part of virtualization is the hypervisor. To perform maintenance on a host server, we need to be able to move all of its VMs onto other host servers with minimum disruption to end users. Even more importantly, if our virtual workloads peak and need more resources, our virtual infrastructure should be able to automatically locate a host server with adequate resources and move the VMs to this host. And the entire process should be completely transparent to end users. VM migration, especially live migration is a desirable feature in Grid and Cloud Computing systems for load balancing, elastic scaling, fault tolerance, and hardware maintenance. The security and reliability issues that reside in VM live migration is a critical factor for its acceptance by IT industry. Though the performance is optimized through live migration, there are two important issues to be noted, reliability and security. In this paper, we propose how to migrate a VM Guest to another VM Host Server. We discuss the steps regarding the KVM live migration requirements and the security and reliability issues in live migration.

Biomass is one source of power generation method. Biomass gasification technology is used to convert the biomass into gas. The gasifier ash extraction operations are controlled by conventional controller like ON-OFF. These types of controllers are providing unsatisfied performance over variations of on pressure drop in the reduction zone and oxygen level of the gasifier. An alternate method is used that is called fuzzy controller. In this paper, a fuzzy controller has been introduced. The proposed controller has to actuate the screw conveyer motor according to the pressure drop in the reactor. The regulate and rate of change of pressure have been verified by simulation.

The principal design problem encountered in wireless communications is how to overcome the distortion of received signals by time-varying propagation path due to the phenomenon called fading. Also, a well known problem of orthogonal frequency division multiplexing (OFDM) i.e the occurrence of high peak- to-average power ratio (PAPR) in the time domain signal reduces the efficiency of transmit high power amplifier.In this paper, we propose a closed loop orthogonal frequency division multiplexing multiple- input multiple-output (MIMO) transmit preprocessing system, where the channel coding method referred as pilot symbol assisted rateless coding (PSAR) is used to mitigate the effects of fading and three PAPR reduction methods are used and the best method to reduce PAPR is chosen. The performance of proposed system is measured in terms of bit error rate (BER) and complementary cumulative distribution function (CCDF) for PAPR. The proposed system achieves about 3 dB improvement in PAPR over the traditional OFDM.

Wireless local area network (WLAN) has become more popular in recent years. With increase in demand users are expecting quality of service (QoS) for multimedia services in WLAN. The legacy protocol IEEE 802.11 and IEEE 802.11e does not provide QoS and fairness for converging traffic in WLAN, so efficient management of protocols are required to provide acceptable QoS for real time traffic and fairness to best effort traffic. In this paper modified wireless token network (MWTN) is proposed to provide the required QoS by decreasing the size of the contention window (CW). This paper analyses legacy IEEE 802.11, IEEE 802.11e and wireless token network (WTN) in terms of throughput, delay, load, retransmission and data dropped performance, for converging traffic in WLAN and compare the results with proposed MWTN, to show that performance of converging traffic is improved in MWTN.

Brain Computer Interfacing is a newly developing field of neuroscience and computer science. Brain Computer Interface (BCI) is a System that provides a non-muscular communication between men and machines. Communication with BCI is done without the use of language or without controlling the computer manually with body parts. We are describing the OpenViBE platform that serves all the necessary steps required in designing typical BCI system. OpenViBE works on EEG signals to measure brain activity. EEG signals on the basis of frequencies and amplitudes are classified into different bands corresponding to different states like sleep, awake, mediation and alert. In this paper we describe the preprocessing, feature extraction, classification and conversion of signals into commands by taking prerecorded EEG signals of real hand movement and motor imaginary movement and convert it into suitable commands that are used to control virtual reality computer application.

As the "artificial pancreas" becomes closer to reality, automated insulin delivery based on real-time glucose measurements becomes feasible for people with diabetes. This paper employs a new approach to regulate the blood glucose level of type I diabetic patient under an intensive insulin treatment. The closed-loop control scheme incorporates the design of robust H¿¿ controller to maintain the normoglycemic average of 80 mg/dl. Due to cost and complexity involved in testing the control algorithms to real patients, studies are done using a Type I diabetic patient model. Controller performance is assessed in terms of its ability to reject the effect of meal disturbance and to overcome the variability in the glucose-insulin dynamics from patient to patient. Computer simulations are used to evaluate the effectiveness of the proposed technique and to show its superiority in controlling hyperglycemia over other existing algorithms.

There are a large number of applications of various DC-DC converters and their usage are increasing alarmingly due to the consciousness of the world towards renewable sources of energy. This paper has made an attempt to design and implement the controlled Boost type DC-DC converter. The converter, inverter and control circuits are modelled and simulated with simple and basic analog circuitries. The converter system converts 36V DC to 230V sinusoidal AC. The control circuit uses Sliding Mode control , used as a 'Voltage Regulator' in this work. This paper presents the simulation results in PSIM(Version 6.0).PSIM provides a good platform for simulation due to its user-friendliness, accurate results and graphs and facilitation of a large number of circuit components. The details about the modelling of power circuit and control circuits are thoroughly presented.

A Grid allows its constituent resources to be used in a coordinated fashion to deliver various qualities of service, relating for example to response time, throughput, availability, and security, and/or co-allocation of multiple resource types to meet complex user demands, so that the utility of the combined system is significantly greater than that of the sum of its parts. Security is a major concern as a grid enables sharing of valuable resources and sensitive information across heterogeneous users. Authentication, message integrity and confidentiality are the major concerns in grid security. The proposed approach uses a trigon based authentication and authorization of the grid entities. Grid service is stateful and transient web service, which can be invoked by clients, and is considered to be the mainstream of future internet. A service is defined by identifying sequences of specific message exchanges that cause the service to perform some operation. By thus defining these operations only in terms of message exchange, we achieve great flexibility in how services are implemented and where they may be located.The creation of Web Services standards is an industry-led initiative, with some of the emerging standards in various states of progress through the World Wide Web Consortium (W3C). The security protocol has been implemented and tested using Globus middleware. To achieve reuse of behaviors of this authentication concept, operations are often grouped together to form a SHA based authentication service using prerequisites as build.xml , globus-build-service.sh, WSDL file and globus as middleware.
网格允许以协调的方式使用其组成资源，以提供各种质量的服务，例如与响应时间、吞吐量、可用性和安全性相关，以及/或多种资源类型的共同分配，以满足复杂的用户需求，因此组合系统的效用明显大于其各部分的总和。安全性是一个主要问题，因为网格支持跨异构用户共享有价值的资源和敏感信息。身份验证、消息完整性和机密性是网格安全的主要关注点。提出的方法使用基于三角的网格实体身份验证和授权。网格服务是一种可以被客户端调用的有状态的、瞬时的web服务，被认为是未来互联网的主流。通过标识导致服务执行某些操作的特定消息交换序列来定义服务。因此，通过仅根据消息交换定义这些操作，我们在如何实现服务以及服务可能位于何处方面实现了极大的灵活性。Web服务标准的创建是一项由行业主导的活动，其中一些新兴标准通过万维网联盟(World Wide Web Consortium, W3C)处于各种进展状态。安全协议已经使用Globus中间件实现和测试。为了实现此身份验证概念的行为重用，通常将操作组合在一起，形成基于SHA的身份验证服务，使用先决条件作为build.xml、globus-build-service.sh、WSDL文件和globus作为中间件。

Rational approximation of fractional order (FO) differ-integrators via Continued Fraction Expansion (CFE) is a well known technique. In this paper, the nominal structures of various generating functions are optimized using Genetic Algorithm (GA) to minimize the deviation in magnitude and phase response between the original FO element and the rationalized discrete time filter in Infinite Impulse Response (IIR) structure. The optimized filter based realizations show better approximation of the FO elements in comparison with the existing methods and is demonstrated by the frequency response of the IIR filters.
