In addition to the functional aspects, Electromagnetic Compatibility (EMC) compliance of electronic devices is one of the important challenges that the developers encounter before the product release. Limiting the EM noise, both conducted and radiated is one of the main requirements to achieve this compliance. The methods defined in the traditional standards have got many shortcomings. Measurement of noise of short duration is an example. Some noises like the transients from a switching device also defeat the traditional measurement procedures. Conventional methods don't prove to be efficient for the measurement of such noises since it is difficult to capture the noise level for the whole frequency range within short duration using a single test receiver. In this paper, we have developed methods that can efficiently measure the short duration noise types mentioned above.Keywords

Wireless Sensor Networks (WSN) with a large number of tiny sensor nodes can be used as an effective tool for gathering data in various situations. Hierarchical cluster based routing protocol were proposed for increasing network lifetime in the WSN. Major issues of cluster based routing protocol are power consumption and over heading which reduces the overall lifetime of the sensor network. In this project we propose a new static clustering protocol technique which partitions the network into static clusters with static cluster heads, eliminating the dynamic over heading and reduces the power consumption thereby improving the performance of the network. The performance of the proposed algorithm will be evaluated with the help of network simulation tool.Keywords

One of the visual indications for the presence of diabetic retinopathy is the exudates in the retina area of Fundus images. Detection of exudates is useful information for the early diagnosis of the eye disease. In this paper, a new approach for the detection of exudates is presented. A position based approach is combined with morphological operations for extracting the optical disc and detect the exudates. The proposed method is applied to the standard retinal image dataset and the results are presented.Keywords
