This work uses an efficient Carry select adder by sharing the Common Boolean logic (CLB) term. After a logic simplification, we only need one OR gate and one inverter gate for carry and summation operation. Through the multiplexer, we can select the correct output according to the logic states of the carry in signal. Based on this modification Square root CSLA (SQRT CSLA) architecture have been developed and compared with the regular and Modified SQRT CSLA architecture. The Modified CSLA architecture has been developed using Binary to Excess -1 converter (BEC). This paper proposes an efficient method which replaces a BEC using common Boolean logic. The result analysis shows that the proposed architecture achieves the three folded advantages in terms of area, delay and power.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"59 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77406872","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}

Recently, there have been a strong interest to use the intelligent tools especially neural networks in energy efficient approach of Wireless sensor networks, due to their simple parallel distributed computation, distributed storage, data robustness, auto-classification off sensor nodes and sensor reading. Dimensionality reduction and prediction of classification of sensor data obtained simply from the outputs of the neural-networks algorithms can lead to lower communication costs and energy conservation. All these characteristics are well considered in the neural network based algorithms such as ART, ART1, FUZZY ART, IVEBF and EBCS.

In this paper, tropospheric delay (TD) is estimated using Hopfield model and RTCA model for a typical LAAS scenario. Hopfield model is used to estimate delay in GPS signal and RTCA model is used to estimate delay in pseudolite signal. As the tropospheric delay is a function of meteorological parameters, these parameter values are collected from India Meteorological Department (IMD) for Hyderabad city, India, for a typical day. These data values are interpolated with respect to altitude for the estimation of TD at various heights. For an altitude of 1.94 m TD in APL signal is estimated as 7.2 m (approx.) and TD in GPS signal is estimated as 2.75 m. When the aircraft just touches the runway touchdown point, TD in APL signal reduces to insignificant value and TD in GPS signal increases to 3.25 m.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"68 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86795472","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 high degree of automation can be attained by using semi supervised learning, because it does not require any pathology modeling. If the dimensionality of the data is large then the estimation of the probability density function is not possible. To overcome this every image is handled as a network of locally coherent image partitions. Median filter is used for preserving edges while removing noise. Contrast enhancement automatically adjusts the intensity values of the image to achieve a better quality. The block wise separation is carried out by calculating the parameter like principal component analysis (PCA), Eigen value, Eigen vector, maximum likelihood function. The maximum likelihood function which estimating the abnormality for each partition is formulated. The likelihood function consists of a model and a data term and is formulated as a quadratic programming problem.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83484695","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 purpose was to determine an optimum classification scheme for this problem and also to infer clues about the extracted features. Wavelets have played an important role in biomedical signal processing for its ability to capture localized spatial-frequency information of EEG signal. CSI is used to develop a normalized index which state the maximum difference between the seizure and non-seizure states between the frequency range of 1-30Hz. The adaptive MSVM works well for high dimensional, multi-class data streams. Decision making was performed in two stages: feature extraction by computing the Combined Seizure Index and classification using the classifiers trained on the extracted features. We have compared the adaptive MSVM with the benchmark EEG dataset. Our experimental results show that the adaptive MSVM with wavelet based features which will represent the EEG signals and the classification methods trained on these features achieved high classification accuracies with better false rate and sensitivity.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"3 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82326154","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 architecture involves an algorithmic (logarithmic) approach for computing floating point numerical operations. It performs all the four basic arithmetic operations using simple hardware like adders, look up tables and interpolation steps. This methodology is used to evaluate a variety of FPU architecture optimizations. The model is being evaluated by comparing with the existing architectures like embedded FPUs and other FPU units in the FPGAs in terms of area, power, speed and high throughput. The simulation results of our model in cadence encounter tool shows the proposed architecture scales nearly 28 percent area and consumes 36 percent less power than existing FPUs.
