Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Boiler efficiency can be also useful in analysis of boiler and can also be used in predictive maintenance of the boiler. How to reduce problems of the boiler efficiency real-time computations and be successful in calculating the boiler thermal efficiency on line are the main concern of operation departments of power systems.

Iris recognition is regarded as the most reliable and accurate biometric identification system available. Here, the segmented iris region is processed to allow comparisons with existing database (Normalization and Enhancement). The normalization process will produce iris regions, which have the same constant dimensions, so that two photographs of the same iris under different conditions will have characteristic features at the same spatial location. To convert iris into dimensionally compatible form, normalization technique was studied and various approaches of normalization are implemented. When needed, these approaches have been modified to achieve better performance. This electronic document represents implementation of various techniques for validation of this work.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"34 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124253531","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 is necessary to access the services such as Internet, Video conferences, and Multimedia applications. WiMax (Worldwide Interoprability for Microwave Access) technology provides Broadband Wireless Access (BWA) in metropolitan areas with a simpler installation and lower cost compare to wired networks. To understand the working of WiMax system and the role of various parameters on the system performance, the simulation model of WiMax physical layer using MatLab 7.5 version has been developed. Efforts have been taken to study the Bit Error Rate (BER) performance of this model under different channel conditions. Efforts are also taken to understand the effect of various Modulation techniques, Coding rates, cyclic prefix factors and FFT size on the system performance. The idea is to help the beginner to understand the system and to make the best possible system selection under different propogation conditions.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114200661","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, if it is applied at the ingress node rather than core node, the complexity in terms of cost of extra delay lines and overhead processing can be reduced considerably. This paper presents a comparative overview of contention resolution methods. A model is proposed based on varying the burst size at the burst generation stage. The results show that there is reduction in time delay and hence the contention is minimized. The comparison of proposed scheme with segment and drop policy of burst segmentation scheme shows that our scheme perform better under low load and extremely better under high load for contention resolution in the OBS network.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115979229","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}

It defines a window around each data points and shifts the center of the window to the mean of the data point though a Mean-Shift Vector till it converges and window shifts to the denser region. The other methods used are Crop Object, Morphological operations, Localize the object by thresholding and area of object.
