The proposed algorithm uses Weighted Local Variance (WLV) of the residual image to determine the texture and fine details. These regions are denoised by bilateral filtering and then, are returned to the image denoised by P-M method. In fact, the WLV have a controlling role in amount of this combination. Denoising the residual image and adding it to the primary denoised image is the main novel idea of this paper. Experimental results confirm this image denoising approach is more efficient than nonlinear diffusion and the bilateral filtering while each algorithm accomplished separately.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115783656","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}

Bifurcated optical fiber sensors can have many applications. Having high sensitivity to short distances, bifurcated optical fiber (Y-sensor) is well suited not only for control applications as position sensors, but also for gauging and surface assessment. In addition, they can be utilized as non contact pressure sensors if used in conjunction with reflective diaphragms moving in response to pressure. Y-sensor can also be applied as temperature transducer if used in conjunction with deformable bimetal sensors.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126895698","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}

A robust adaptive neural network (NN) control is investigated for a general class of uncertain single-input-single-output (SISO) discrete-time nonlinear systems with unknown system dynamics and input nonlinearities i.e. combination of saturation and dead-zone. For input nonlinearities, discrete-time SISO nonlinear system in combination with back stepping and Lyapunov synthesis is proposed for adaptive neural network design with guaranteed stability. The actuator nonlinearities are assumed to be unknown and compensated by a pre compensator using Chebyshev neural network (CNN) and unknown nonlinear functions are also approximated by CNN. Weight update laws, based on Lyapunov theory are derived to make this scheme adaptive and the convergence properties are shown. Simulation results validate the effectiveness of proposed scheme.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126166007","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}

There is therefore an upper bound (threshold) on the number of wavelength conversions that a signal can go through when it is switched optically from its source to its destination. Our test results have shown that the blocking performance of optical routing could deteriorate significantly under the impact of the conversion cascading constraint. In this paper, we review the negative impact of wavelength conversion cascading on the performance of all-optical routing and we examine the implications of the presence of the conversion cascading constraint on the validity of the performance results for two previously proposed routing protocols for optical networks.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126221513","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}

Real-time signal processing requires high speed and high throughput Multiplier-Accumulator (MAC) unit that consumes low power, which is always a key to achieve a high performance digital signal processing system. In this paper, design of MAC unit is proposed. The multiplier used inside the MAC unit is based on the Sutra \"Urdhva Tiryagbhyam\" (Vertically and Cross wise) which is one of the Sutras of Vedic mathematics. Vedic mathematics is mainly based on sixteen Sutras and was rediscovered in early twentieth century. In ancient India, this Sutra was traditionally used for decimal number multiplications within less time. The same concept is applied for multiplication of binary numbers to make it useful in the digital hardware. Here, the coding is done in VHDL and synthesis is done in Xilinx ISE series. The combinational delay obtained after synthesis is compared with the performance of the \"Modified Booth Wallace Multiplier\" and \"High speed Vedic multiplier\" presented by Ramesh Pushpangadam. Our proposed Vedic multiplier seems to have better performance.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125661667","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}

The proposed strategy (strategy 2) has been analyzed for multiclass traffic scenarios.

Data aggregation for WSNs must address to the issues of WSNs like limited energy in battery powered sensor, and fast and efficient query response which is essential to network performance and maintenance. In TDMA protocol, during the data aggregation sensors nodes consume different energy in different radio states (transmitting, receiving, listening, sleeping, and being idle) and also consume energy for state transition from sleeping to wakeup. Our proposed Energy Efficient scheduling (EES) algorithm reduces state transitions of radio in sensor node there by reducing the energy consumption. Sensor node activity is scheduled so that in wakeup state reception and transmission activities are continuously performed by nodes before going in to sleep state. Our protocol also focuses on reducing co-channel interference and efficiently use of bandwidth.","PeriodicalId":292190,"journal":{"name":"2011 International Conference on Computational Intelligence and Communication Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128422933","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}
