Accountability is an important aspect of any computer system. It assures that every action executed in the system can be traced back to some entity. Accountability is even more crucial for assuring the safety and security. A major feature of the cloud services is that users' data are usually processed remotely in unknown machines that users do not own or operate. Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis, we propose a novel highly decentralized information accountability framework to keep track of the actual usage of the users' data in the cloud. In particular, we propose an object centered approach that enables enclosing our logging mechanism together with users' data and policies. We influence the JAR programmable capabilities to both create a dynamic and travelling object and to ensure that any access to user's data will trigger authentication and automated logging local to the JARs. To strengthen user's control, we also provide distributed auditing mechanism.

Biometrics-based authentication is a verification approach using the biological features inherent in each individual. They are processed based on the identical, portable, and arduous duplicate characteristics. The principal lines and texture are two kinds of salient features of palmprint. A few years ago , a new branch of biometrics technology, palmprint authentication was proposed whereby line and points are extracted from palms for personal identification. In this paper, we consider palmprint as a piece of lines and texture and apply palmprint identification techniques for extracting feature to palmprint authentication.

Hence the re-ranking concept arises to re-rank the retrieved images based on the text surrounding the image and metadata and visual feature. In this paper, we propose an “Image Search Re-ranking Based on Prototype” a prototype based method to learn reranking function from human labeled samples . Based on images obtained in initial search result , visual prototype will be generated. Each prototype is used to construct a meta reranker to produce a reranking score for any other image from initial set. Finally all scores from all meta rerankers are aggregated. For visual reranking we use SVM algorithm.

Because two words can have same meaning e.g. if query "block size" is entered in search engine then search engine will display the records related to operating system as well as the living apartment block size. But search engine don't know about what actually user expect. That is data related to operating system or data related to living apartment. So generally it will display both type of links In this paper we are managing the search engines on the fly. That is the paper is related to personalize the search of user on the fly without asking users to tagging or rating for the page.

The first technique is known as Volume Rendering and the second technique is known as the Marching Cubes Algorithm. Both techniques use voxels (3D square pixels) to determine the 3D area to be constructed. The Marching Cubes (MC) algorithm by Lorensen and Cline is most popular algorithm for extraction of isosurface out of volume data. Several drawbacks of MC algorithm are solved by using new improved version of MC algorithm. We proposed an improved version of the Marching Cubes algorithm which gives a topologically correct triangular approximation of the isosurface for any cube configuration. Unlike the past work on Marching Cube algorithm, a robust triangulation strategy, complementary and rotation operations is presented. Our algorithm is adaptive to the small the changes of data or the small changes of the threshold, and obtains more reasonable result of triangulation of isosurface than those produced by standard MC algori...

Mortality data of 1,553 COVID-19 cases from a tertiary care hospital between March 2020 to September 2021 were analyzed. Maximum deaths occurred between 18:01 hours to 06:00 hours of the 24-hour cycle. There is a significant statistical association between time of death and age, time of death and sex, time of death and having a comorbidity of diabetes mellitus in the study sample. The study confirms that the chronofatality of COVID-19 deaths has a nocturnal predilection. The circadian rhythms of glucocorticoids, respiratory physiology of sleep, and circadian hemodynamic variations ma...

This is achieved by developing an implementation of Marching Cubes, a surface construction algorithm that’s currently the standard used for 3D surface construction in the medical visualization industry. Two techniques have been chosen to produce the 3D models. The first technique is known as Volume Rendering and the second technique is known as the Marching Cubes Algorithm. Both techniques use voxels (3D square pixels) to determine the 3D area to be constructed. The Marching Cubes (MC) algorithm by Lorensen and Cline is most popular algorithm for extraction of isosurface out of volume data. Several drawbacks of MC algorithm are solved by using new improved version of MC algorithm.

An Efficient Blocking System for Hacking Users in Anonymizing Networks

The success of such networks, however, has been limited by users employing this anonymity for abusive purposes such as defacing popular websites. Usually, web site administrators rely on IP-address blocking in order to disable access to misbehaving users, but it is impractical if the abuser routes through an anonymizing network. In order to avoid this, administrators block all known exit nodes of the anonymizing network, denying anonymous access to misbehaving and behaving users alike. To solve this issue, we introduce Nymble, a system where servers blacklist misbehaving users, thereby blocking users without affecting their anonymity. In Nymble, (1) honest users remain anonymous and their requests unlinkable; (2) a server can complaint about a particular anonymous user and gain the ability to blacklist the user for fut...

One of the most popular algorithm is Apriori algorithm that is used to extract frequent itemsets from large databases. Based on this algorithm, this paper is organized into two parts in first part of paper an Improved Apriori Algorithm is being presented that efficiently generates association rules. These reduces unnecessary database scan at time of forming frequent large itemsets. In second part of this paper we have tried to give contribution to improved Apriori algorithm by hiding sensitive association rules which are generated by applying improved Apriori algorithm on supermarket database. In this paper we have used innovative approach that strategically modifies few transactions in transaction database to decrease support and confidence of sensitive rule without producing any side effects.

During routine cadaveric dissection of thoracic region in an adult male, we found an abnormal venous channel which was single and was lying on the left side of the vertebral column. It received tributaries from superior intercostal vein and posterior intercostal veins. We found this abnormal venous channel draining directly into left brachiocephalic vein in contrast to its usual drainage into azygos vein. Hence this can be considered as abnormal venous channel and variant of hemiazygos vein and accessory hemiazygos vein. The azygos and hemiazygos venous system is commonly encountered during surgical intervention performed on posterior thoracic wall. This case report provides a new data of potential clinical significance.
