It enhances the K-means clustering algorithm (Linde-Buzo-Grey) so that the number of clusters is determined at run time. The paper uses radar classification problem as an example application. Most of naturally existing processes possess Gaussian distribution because of central limit theorem. This paper assumes that parameters of radars are Gaussian. Chi-squared test for goodness of fit is used far evaluating the hypothesized distribution from sampled data. The data is divided and output of chi-squared test is used to decide whether to carry on sub-clustering or not. Test results on simulated data are shown to demonstrate the working of algorithm.","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125471796","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 usage of voice and video applications over these networks has created various challenges for research community. Real-time applications require certain guarantees in terms of throughput, delay, jitter and packet loss ratio from the underlying network. Legacy MAC layers do not provide service/traffic differentiation and treat both real-time and best-effort traffic equally. We propose an architecture for heterogeneous ad hoc networks that provides service differentiation. It gives better treatment to high priority traffic. More transmission time is allocated to high priority traffic, which improves its throughput and reduces end-to-end delay. Real-time traffic is allowed to transmit a burst of packets without contending for channel access, known as transmit opportunity (TXOP). A novel route, repair scheme, called AODV real repair (AODV-RR) is also proposed that tries its best to locally repair a broken route and minimize the real-time packet loss under heavy traffic load","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124540613","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 paper is a continuation of our previous papers in which we discussed the design and digital control routine of a 2DOF stable platform with coupled joint. In the previous paper we implemented a non-model based PI controller that proved sufficient for static targets, however for image based tracking, a number of non-linear forces are affecting the system and such scenarios require model-based controllers. The design of model based controller starts with model selection and then the estimation of its parameters.

The combination of different sources of information about a face, in the form of different feature sets and classification methods, provides an opportunity to develop an improved level of verification compared to the use of a single set of classifiers. Recently, the face recognition method based on principal component analysis (PCA) and directional filter bank (DFB) responses is integrated with voting algorithm. We look at the possibility of using cross correlation as a measure to compare the outputs of various classifiers. In our system recognition ability of the PCA is enhanced by providing directional images as inputs and then using the normalized cross correlation as a decision fusion measure. The proposed method fuses the decisions of DFB-PCA on the basis of maximum cross correlation of each directional test image with mean of its respective directional class.

This capability is crucial for classifying approaching enemy ships and aircrafts. The sensed parameters may vary from their actual or reported values because of man-made variations in the form of agility or staggering. Another cause of variation could be dispersion because of atmospheric effects and equipment noise. Associating the measured radar parameter set with a know sighting is a pattern recognition problem in multi-dimensional space. Various research authors have attacked the problem with various data association tools with different merits and de-merits. Most of them are marred by the massive computing power required and unrealistically large training data requirements.
