The penalty is increased complexity of the central node. This is a major problem because the central node is expected to have significantly more power and processing resources. On the distributed case, the coordinator (Distributed Coordination Function) only sends the active nodes to the sensors to keep the reliability and consumes less energy. As a result of this analysis, distributed mechanisms for QoS in WSNs built which extend wide area applications. This paper presents an energy-efficient aware of MAC application specific protocol with enhanced, integrated type in the distributed environment.

Although cybertherapy is at its development stage, a great potential can be reaped when it is moulded in the right way. Clinical virtual reality is found to be a promising way of distracting the patients from sensing the pain during medical procedures, physical rehabilitation or post-traumatic stress. There exists no single pain management methodology that is good for everyone, or even the majority of people. Research findings prove that pain has many causes and courses, and can impact individuals in a multitude of ways including the behavioral, physiological, emotional, psychological, social and spiritual levels. Though distraction through audio visual aids has a significant effect in decreasing the intensity of pain signals in the brain, the analgesic efficacy has to be well researched and improved. The perception of pain varies with factors such as age, ethnicity, sex and genetics. Increased nervousness of patients in virtual world, patients' confidentiality, subjectivity in effectiveness on individuals, array of pains to be handled with a single virtual platform and cost are the major barriers to be tackled. This paper discusses ways of providing such generic, acceptable and proven methods of cybertherapy. Such virtually painless world shall be greatly achieved only with close cooperation between technologists and medical experts.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114982279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However the resources available in a single datacenter are limited. Thus if a large demand is observed in a given time, a cloud provider is not able to deliver a uniform QoS. To avoid this scenario, I enable the application to scale it across multiple independent cloud datacenters by forming federated clouds. In such a case, from the customer's point of view it is always difficult to decide whose resources they should use. To handle this case a ranking mechanism is proposed which measures the quality and prioritize the cloud resources. In this work I propose a framework and mechanism for coordinator based advance reservation and ranking of cloud resources which allows the users to book resource in advance. Advance reservation provides guaranteed delivery of resources to the right customers at the right time.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124641485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This new vehicle identification technique consists of vehicle detection, plate localization and character recognition. Here, Genetic algorithm (GA) is employed at two levels: for detecting vehicle from traffic image and recognizing character from the number plate. Detection is based on contour and shape information. GA controls the window size to capture each vehicle in a separate widow. Connectivity and adjacency concepts are used to locate and extract number plate and its characters. A digital board (DB) with window panes is introduced to recognize each character uniquely. GA is adopted at the second level to map character pixels into the window panes as lines. For each character in the number plate, distinct feature vector is computed. Finally, a feature based matching is adopted for character recognition. Experiments have been conducted with images taken from various scenes and conditions and the detection rate is found to be 92.5 %. Experiments have conducted for recognition with LPR images taken at different conditions and the recognition rate is found to be 91 %. Detection time is linear function of number of objects in the input image. Potential applications include provisioning of vehicle parking facilities and campus security system for permitting authorized vehicles into the premises.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129459387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For real time applications it is mandatory that a differentiator should have as small an order as possible. Different procedures available for the design of FIR and IIR type digital differentiators are presented. The IIR Type digital differentiators are obtained by inversion and magnitude stabilization of the existing digital integrators. In some applications like controls, waveshaping, oscillators and communications require a constant 90° phase for differentiators. In this paper an attempt is made to study about the variation of phase angle of digital differentiators with the application of fractional delay. The use of digital differentiators for the detection of edges in an image, QRS detection in an ECG signal is illustrated. It has been observed that the digital differentiators have shown superior performance compared to the well known gradient method. With the proven efficiency of the differentiators in various applications, they have been implemented in hardware using Verilog.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125398681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As energy and cooling constraints limit increases in microprocessor clock speeds and number of cores, computer companies are turning to parallel programming. Nowadays, parallel programming is achieved by increasing the number of processing elements in processor cores, increasing the number of processor cores itself and complicated parallel programming where programmer has the responsibility of allocating memory and synchronizing the communication between the processing elements as well as processor cores. It becomes increasingly difficult and expensive to design and produce shared memory machines with ever increasing number of processors. Increase in the number of processors is a major disadvantage when it comes to energy consumption. In this work, we present a new architecture for processor design based on pairwise balanced combinatorial interconnection of processing and memory elements. The proposed processor uses two operand instructions, so that the set of executable machine instructions is partitioned by these pairs. This kind of partition allows parallel processing of data-independent instructions. Since this partition is done at the compile time, the architecture extracts the instruction level parallelism without run-time overheads. We analyze and confirm the performance improvements through simulations. The suggested combinatorial arrangement gives set of architectures with various degrees of performance enhancement.","PeriodicalId":286985,"journal":{"name":"2012 Fourth International Conference on Advanced Computing (ICoAC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127870133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
