Cooperative Beamforming is a flourishing technique to resolve many issues related to Cognitive Radio Networks. One of them is to overcome the problems caused by failure of several nodes in a network. In case of node failures, the optional paths are selected instead of intended paths which may cause additional delay. This work suggests a route conservation protocol with minimal changes in a basic routing protocol. In the aid of Cooperative Beamforming, fellow nodes try to blend in with cooperative environment to prevent transmission at primary receiver. The key purpose is to increase the quantity of nodes used in cooperative beamforming. Several simulations are carried out in NS2. The reliability of proposed protocol can be determined in terms of throughput, PDR(Packet Delivery Ratio) and end-to-end delay, by accomplishing minimal rate. The manipulation of proposed protocol in combination with other available routing protocols is easily possible. © 2016 IEEE.

Scheduling of task and resources using an efficient task scheduling algorithm improvise the efficiency and throughput of the cloud server. Scheduling in cloud is based on selection of best suitable resources for task execution, by considering various QoS parameters. Priority based task scheduling by mapping conflict-free resources and workload in cloud computing environment is the proposed scheduling method in this paper. This will result in conflict-free resource allocation to the task based on priority and a balanced workload scheduling. In this technique task scheduler and resource scheduler will work co-ordinately to achieve the desired throughput with the minimum response time. The main objective of this paper is to have maximum utilization on client and server side accessing the cloud environment.

The reduction of vibration and noise is a major requirement for performance of any vibratory system. Due to legislative pressures in terms of external pass by noise limit of vehicles and customer requirements for better noise and ride comfort in vehicle, NVH attribute has become an important parameter. Major sources for vehicle pass-by noise consist of powertrain, tire and wind. Damping treatment is important to reduce vibration and noise radiation. The passive constrained layer dampening (CLD) treatment can be used to reduce structure-borne noise of vibrating structure using viscoelastic damping material. The performance of the passive constrained layer damping treatment can further be enhanced by new segmentation technique. The concept of segmented CLD is based on edge effect. The efficiency of segmenting a constrained layer damping treatment relies on the fact that a high shear region is created in the viscoelastic layer. The shear deformation in the viscoelastic material is not significant in regions where the bending moment is maximal. Segmenting induces shear in the damping layer and thereby increases damping ability. A cut in the damping treatment gives an additional shear deformation at that position. Hence a cut has to be located at the maximum displacement. The position of maximum displacement for all the first four bending modes is identified by bending mode shape. The bending mode shapes are obtained by MATLAB program. The damping performance is further increase by using multiple cuts in CLD beam. The optimized positions of multiple cuts are obtained by Genetic Algorithm (GA) optimization technique. The damping performance of CLD beam is measured in terms of vibration response (dB) and composite loss factor ().This paper focused on comparison of damping performance of full CLD treatment and segmented CLD treatment. The experimental investigation is performed by using Accelerometer, Impact hammer and FFT analyser (B&K make). The new innovative segmented CLD treatment is found to be very much effective.

With the rapid spread of radio communication network including cellular phone, Radar Communication System, Navigation, Internet Communication Satellite communication etc., the ANTENNA is basic device which is used in all communication systems. Its proper design is essential to run those systems effectively and gainfully. Conspicuously wide antennas for various transmitting and receiving stations installed on steel towers, suburbs and on the roofs of the buildings and tops of the electrical poles and towers in the city and also in rural area. Thus antenna is the backbone of the any radio wave and microwave communication system. The antenna is usually lightweight, low cost, easily machinable electrically good conductor device. It is mainly divided into two groups (1) External antenna and (2) Internal antenna. External antenna is large in size, material cost is also high and in practice it has more radiation losses. It can be reduced by modern design techniques but its shape and size again incorporates a major problem while interface with the communication devices. However, internal antenna brought in to practice so that, it is easily interface with the any communication system. Numerous design techniques have been used from many years to design the perfect and proper internal antenna. Thus internal antenna is proven benchmark device used in the wireless communication system. Well-known antenna widely used in this area which is known as MICROSTRIP ANTENNA. This paper mainly focuses on the design of miscrostrip antenna to meet the industrial design problems so that it works properly and precisely. Many more design tools and techniques have been used to getting progressive performance of it. As the operating microwave frequency changes or fixed the designed antenna with respect to derived parameters may not give satisfactorily performance. The skilled or expert designer on his experience does changes in the derived design parameters and complete the task so that perfect fitting of the parameters (Patch width W, Length L substrate density etc. ) resulting increases its performance. Hence it translates the designer's knowledge into correct parameter setting. The paper describes proposed work to design and develop a Microstrip Antenna employing conventional mathematical model design which acquires constant environmental conditions for propagation of microwave. In this paper Fuzzy logic technique is effectively used to design and development of miscrostrip antenna which is based on the fuzzy set theory. Also it is proposed to develop Fuzzy Inference System (FIS) on the basis of expert design knowledge and experience. Finally test performance of the conventional design of microstrip antenna and fuzzy based design antenna has been compared. To avoid computational complications it is proposed to use the computer with MATLAB software. It is also proposed that designed microstrip antenna properly interfaced and then it will be tested for performance. Unique computer program also (source code) developed which is useful to fast and easy computation work. In actual practice of this work, Patch length L and width W is taken as input variables and frequency as output variable in the FIS. This paper concludes that fuzzy based design and developed technique is found to be most suitable for betterment of miscrostrip antenna. © 2015 IEEE.

This paper presents a no-reference image quality assessment, targeted towards blur distortions based on the study of human blur perception for varying contrast values. A probabilistic framework is developed based on the sensitivity of human blur perception at different contrasts. Utilizing this framework, the probability of detecting blur at each edge in an image is estimated. The blur perception information at each edge is then pooled over the entire image to obtain a final quality score by evaluating the cumulative probability of blur detection. Proposed metric is able to predict relative amount of blurriness in images. Higher metric value represent less blurred image. Results are provided to illustrate the performance of proposed metric. Performance of proposed metric is compared with existing no reference image quality metric for various publically available image databases. © 2013 IEEE.

Many classes of images contains spatial regions which are more important than other regions. Compression methods which are capable of delivering higher reconstruction quality are attractive in this situation for the important parts. For the medical images, only a small portion of the image might be diagnostically useful, but the cost of a wrong interpretation is high. Hence, Region Based Coding (RBC) technique is significant for medical image compression and transmission. Lossless compression in these 'regions' and lossy compression for rest of image can helps to achieve high efficiency and performance in telemedicine applications. This paper proposes an automated, efficient and low complexity, lossless, scalable RBC for Digital Imaging and Communications in Medicine (DICOM) images. The advantages of RBC are exploited in this paper, segmenting the region into various regions of importance and subjecting varying bit-rates for optimal performance. Moreover, the combined effects of Integer Wavelet Transform (IWT) and bit-rate limiting compression technique for lesser important regions helps reconstruct the image, reversibly, up to a desired quality. The overall compression thus reaches a satisfactory level to be able to safely transmit the image in limited bandwidth over a telemedicine network and reconstruct diagnostic details for treatment, most faithfully. © 2012 The Institution of Engineering and Technology.
