Content Based Image Retrieval (CBIR) system supports users to retrieve relevant medical images based on their features. Current content based image retrieval systems are incapable of providing exact results to the users. To address this problem a consistent feature extraction method is required for content based medical image retrieval system to extract similar features from the images. In this study discrete curvelet based feature extraction technique is proposed to retrieve similar images and the similarity distance is calculated by using Euclidean distance. The proposed method gives better precision and recall rate. Experimental results on a database of 200 MRI images.

Recently, economic scenario is often facing security breach that has heavy impact on the financial soundness of a company particularly, stock prices on firms. The utmost consequence being the whole business comes to a standstill. From the estimates attributed by the financial sector, it has been inferred that the loss incurred on virus and worms attack is said to have the greatest impact that hampers the prosperity of a business entity. Thus, security strategies attempt on revolving around the act of security breach, thereby targeting to curb the financial losses of a company totally or at least minimize the losses. If the operating system of the stock market or financial sector gets corrupted the whole system need to be formatted, a new operating system has to be reinstalled and the antivirus software tends to be useless in such cases. In this study, virus and worms are encountered using IPTraceback technique and network security is ensured. The effective integration of spectral analysis, worm detection and IPTraceback, alerts the user dynamically and kills the source which distributes the virus. Real time traffic data are used for evaluating the performance.

Idiopathic condylar resorption (ICR) is a condition with no specific cause. Condylar resorption occurs more frequently in women because of the pathogenesis of sex hormones. Cone-beam computed tomography and magnetic resonance imaging are vital imaging methods for diagnosis of Idiopathic condylar resorption.The symptoms of ICR overlap with osteoarthritis, inflammatory arthritis, physiologic resorption/remodeling, congenital disorders affecting the mandible.Thus a thorugh medical and physical history is essential in understanding the pathogenesis of idiopathic condylar resorption.Idiopathic condylar resorption can be active or passive.. This review provides an early glimpse of low estrogen and idiopathic condylar resorption.
