Heartbeat based mechanisms are used to detect the failure and recovery event at a particular node. A diagnosis algorithm has been simulated and the results are presented. The result shows that failure and recovery events both take a constant time, i.e., O(1) round and has been compared with algorithm FHB.

Our method requires manual drawing of contour on the first frame of the image sequence to represent the left ventricle boundary. Heart wall tracking from echocardiographic image is a difficult task because of poor signal-to-noise ratio and presence of speckle noise. For speckle noise removal adaptive weighted median filter is used. Tracking results obtained by using our proposed UKF based method are compared with results obtained by using Kalman filter (KF) based tracker. The root mean square error (RMSE) between actual and tracked boundary of the heart wall is calculated for each pixel using both these methods. It is observed that RMSE produced by UKF based tracker is less than that produced by KF based tracker","PeriodicalId":122715,"journal":{"name":"2006 Annual IEEE India Conference","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115281004","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 bias-free and less noisy radar measurement is critical as it would provide correct information of target kinematics which is a necessity of the guidance law to generate the tracking commands. In a typical interception scenario, multiple radars are employed to detect and track target kinematics. Bias estimation is often difficult because of limited observability of sensor biases as there may not be a unique set of biases that explains the relative errors between measurements. The sensors involved may be dissimilar, and their corresponding bias parameters may differ in magnitude and type. The various sources of biases are sensor bias, alignment error (tilt error), and radar position uncertainty. Radar measurements are to be debiased and noise filtered effectively before they can be used singly or in conjunction with any onboard sensor for generating tracking commands. The formulation of bias estimator described here is designed for tracking systems, such as aircrafts, ships, with multiple sensors as radars, jam strobe detectors, GPS, ESM and wider variety of targets and sensors. The paper concisely states the algorithm which addresses the above mentioned problems and illustrates its performance capabilities through results obtained by applying it to a realistic ballistic target tracking scenario","PeriodicalId":122715,"journal":{"name":"2006 Annual IEEE India Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115921323","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}

Data fusion in IR usually combines the various retrieval schemes (strategies) to enhance the performance of the IR systems. Though, the fusion operation successfully combines the merits of all participating member strategies, some of them may affect it's performance. Hence, it is essential to eliminate role of the worst performing members. This paper focuses on a method, which effectively combines the best functioning schemes. In the proposed approach, assignment of the final relevance score to the documents is based on the principle of signal to noise ratio. An algorithm is used to separate the best performing (information bearings) schemes from the worst (noise) ones. The presented method is tested in three test document collections namely ADI, MED, and CISI and it has been identified that, the proposed approach results in significant improvement over the existing Comb-functions for combining scores","PeriodicalId":122715,"journal":{"name":"2006 Annual IEEE India Conference","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122559442","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 scarcity of fresh water has been one of the motivating factors in developing efficient irrigation systems. Apart from the environmental concern in water management, it facilitates better growth of the crops. Fertilizers in low quantities can considerably retard crop growth and hence affect production. Synthetic fertilizers in high quantities pollute the soil and render ground water unsuitable for consumption. Measuring the nutrient availability in real time and properly delivering the right amount of the nutrients at the appropriate time can be immensely useful. The primary objective of SWARM is to remotely monitor the water and nutrient availability and deliver the corresponding resources dynamically in accordance with the data collected. The SWARM system was implemented at a farm measuring 250 ft times 80 ft in Kuppam, Andhra Pradesh, India. Groundnut is being cultivated in the farm. It was tested for a period of around one and a half months and results have been provided. The system has shown promising results when compared to manually supplying water and fertilizers.
