The task is to analyze, how different services can be designed for the SegBus multiprocessor platform and observe the improvement in system performance. In this paper, we utilize the concept of broadcasting and multicasting service from standard data bus for multiprocessor systems to enhance the performance of SegBus platform. The running example is represented by the H.264 encoder. The SegBus platform...
Knowledge constantly grows in scientific discourse and is revised over time by domain experts. The body of knowledge will get structured and refined as the communities of practice concerned with the field of knowledge develop a deeper understanding of issues. The knowledge model, as a result evolves to a new state to accommodate the new knowledge. Keeping trail of these changes in semantically rich...
In this paper we approach the performance aspects of MPSoC platforms, from the point of view of IP placement with the focus on network-on-chip (NoC). Proper IP placement is important for several time-dependent applications such as video and voice where traffic must be delivered on time in order to operate properly. Proper placement of IPs can lower the traffic congestion, improve overall execution...
Effective information retrieval in digital libraries requires semantic alignments of documents with taxonomy. The alignments provide the semantic description of documents. The proposed methodology aligns documents using the hierarchical structure of taxonomy. It refines the results of the existing semantic key phrase extraction algorithm. The evaluation shows promising results.
The paper presents a Domain Specific Language (DSL) for a multi-core segmented bus platform, SegBus. The DSL, based on a UML profile, consists of graphical platform elements in the form of stereotypes with the necessary tagged values to depict platform aspects at high level of abstraction. Customizations are applied to each stereotyped element in the form of user-defined rules to restrict relationship...
Modular Exponentiation is at the heart of various arithmetic architectures used in most Public Key cryptography algorithms. Modular Exponentiation of large numbers requires excessive processing. An efficient implementation of modular exponentiation may help overcome the speed issues of public Key Cryptography. in this work, the most promising technique of Montgomery modular exponentiation and its...
In this paper, a semantically enriched preference-based meeting scheduler is proposed. By committing to ontologies, machine can understand and reason about the information such as events and schedules. Therefore meeting scheduling ontology is constructed for describing the domain knowledge of meeting scheduling system. For describing the behavior of attendees, semantic meeting scheduling system (SMSS)...
Ontologies changes in the sense of constantly growing in scientific discourse and being revised over time by different people. It refers to the fact that groups of professionals over time (e.g. in a longer term project) develop a common understanding based on joint interpretation of a shared terminology. The terminology will get structured and refined as the Communities of Practice concerned with...
Distributed repositories, containing digital documents are usually maintained and managed independently according to organization/users own requirements. Same information (i.e. documents containing same information) in different repositories, may be represented differently, makes it hard to retrieve desired information. Keyword based information retrieval technique helps in improving recall of user...
New challenges are raised with the large increase in the number of Web accessible data sources such as (a) identification of data sources that are relevant to the user query and (b) fulfilling the requirements of user's queries. Commonly used integration systems are facing problems because (i) sources are semantically heterogeneous and are autonomous; (ii) their schemas and database design are different...
Digital repositories can preserve terabytes of information in the form of digital documents. Searching these digital documents requires time and computing resources. Techniques are required to efficiently process these digital repositories. Metadata and semantic annotations can augment the overall search process and provide a foundation to build intelligent applications by using the documents in the...
In this paper we present our work on personal information management by exploiting both context ontology and landmarks. The context model introduced is based on location, agent, time, and category of information corresponding to the 4 Ws: where, who, when, and what. Each of them represents one dimension of an information item. Semantics of each dimension are explicitly described in the ontology for...
