Semantic Web is a vision for future of the current Web which aims at automation, integration and reuse of data among different Web applications. Access to resources on the Semantic Web can not be controlled in a safe way unless the access decision takes into account the semantic relationships among entities in the data model under this environment. Decision making for permitting or denying acce...

In order to elucidate the role of gap junctions in adrenal cell responses, we measured the effect of inhibiting gap junctions with 18-alpha glycerrhetinic acid (GA; a potent inhibitor of cell-cell communication) and connexin antisense transfection on cell proliferation and adrenocorticotropin (ACTH)-stimulated steroidogenesis. In these experiments we utilized a bovine adrenocortical cell (SBAC)...

ÐThis paper presents a Similarity-Based Agglomerative Clustering (SBAC) algorithm that works well for data with mixed numeric and nominal features. A similarity measure, proposed by Goodall for biological taxonomy [15], that gives greater weight to uncommon feature value matches in similarity computations and makes no assumptions of the underlying distributions of the feature values, is adopted...

This paper represents the Algorithm for various Coding standards such as Huffman coding, Syntax based arithmetic coding and Context Adaptive Binary Arithmetic Coding used in MPEG, H.263 and H.264 respectively and their analysis. We found that average bit per symbol (average code word length) for Huffman coding is nearly equal to Entropy which is the basic requirement, for different bit rate PSN...

In this paper, we use a session-based workload to measure a performance of a commercial web server. We dene a session as a sequence of client requests. An overloaded web server can experience a severe loss of throughput when measured as the number of completed sessions. Moreover, the overloaded web server discriminates against longer sessions. Session based admission control (SBAC), introduced ...

Carbon-based materials with great adsorption performance are of importance to meet the needs industrial gas adsorption. Having massive agricultural wastes sugarcane bagasse, China could use this waste into wealth. However, comprehensive utilization bagasse as precursor for biochar that can be used adsorbent has not been extensively explored. In study, a series in situ sulfuric acid–modified was...

A Virtual Organization (VO) consists of some real organizations with common interests, which aims to provide inter organizational associations to reach some common goals by sharing their resources with each other. Providing security mechanisms, and especially a suitable access control mechanism, which enforces the defined security policy is a necessary requirement in VOs. Since VO is a complex ...

Popular Internet applications deploy a multi-tier architecture, with each tier provisioning a certain functionality to its preceding tier. In this paper, we address the challenging session-based admission control issue for multi-tier Internet applications. The session-based admission control approach (SBAC) designed for a single Web server is not effective for a multi-tier architecture. This is...

Understanding how information is integrated and processed in single neurons and small circuits is crucial for comprehending information processing in neural circuits, and will help elucidate the biophysical basis of cognition and cognitive dysfunction. The direction selective circuit of the retina has been an archetypical model for understanding how neural circuits process information in the br...

ÐIn this paper, we consider a new, session-based workload for measuring web server performance. We define a session as a sequence of client's individual requests. Using a simulation model, we show that an overloaded web server can experience a severe loss of throughput measured as a number of completed sessions compared against the server throughput measured in requests per second. Moreover, st...
