This paper presents a parallel infrastructure for reliable numerical simulations of the bone-conducted sound in the human head. We focus on the three dimensional finite element modeling of the acoustics of human head. The human head is modeled with three dimensional tetrahedral finite elements with high polynomial orders of approximation. A fully coupled model based on the acoustic/elastic interaction problem with a detailed resolution of the cochlea region is formulated and solved. The parallel infrastructure is based on the domain decomposition paradigm. The computational mesh is partitioned into multiple sub-domains, and the multi-level direct substructuring parallel solver is utilized to solve the coupled problem.

Measuring knowledge assets of a company is difficult. Most existing approaches either fail to select the right indicators, to facilitate aggregation of indicators, to reveal correlations between indicators or to forecast future indicator values. An approach to overcome these obstacles using Computational Intelligence (CI) is introduced. Different CI techniques are used to enhance two prominent knowledge assessment approaches, the Intellectual Capital Navigator and the Technology Balance.

We have created and implemented an ontological model, which addresses the problem of data sharing and interoperability in a heterogeneous hospital computing environment. We have also used semantic web tools and reasoning mechanisms to achieve our aims and have demonstrated that it is feasible to share heterogeneous data across hospital environments and create an intelligent awareness for software applications built within them.

Smart Rooms integrated with sensors, actuators, wireless networks and context-aware applications will soon become part of our daily life. To build successful context-aware systems, we must develop an architecture to reduce the difficulty and cost of building these systems. This paper presents the architecture of ChaturKartha, developed to setup a context aware intelligent Room. Based on the gathered contextual knowledge, ChaturKartha infer what the users expect and accordingly delivers the expected services. Our architecture explores the use of Semantic Web languages for defining context ontology and for reasoning over such information.
In this paper we propose a flexible task distribution mechanism in order to reduce the time spent in rendering complex 3D scenes. This kind of mechanisms are particularly useful when adopting a fine-coarse approach, t...

Grid computing has made substantial advances during the last decade. Grid middleware such as Globus has contributed greatly in making this possible. There are, however, significant barriers to the adoption, of Grid computing in other fields, most notably day-to-day user computing environments. We will demonstrate in this paper that this is primarily due to the limitations of the existing Grid middleware which does not take into account the needs of everyday scientific and business users. In this paper we will formally advocate a Grid Operating System and propose an architecture to migrate Grid computing into a Grid operating system which we believe would help remove most of the technical barriers to the adoption of Grid computing and make it relevant to the day-to-day user. We believe this proposed transition to a Grid operating system will drive more pervasive Grid computing research and application development and deployment in future.

Layered media delivery, such as multiview video coding (MVC) or scalable video coding (SVC), provides new opportunities for mobile multimedia services. In this paper, we propose a novel approach called unequal loss protection (ULP)-Strider based on Strider codes [1], which provides extra protection for layered media delivery. ULP-Strider introduces minimum distance transmission (MDT) in symbol level and soft hint for transmission to improve the probability of decoding process. We implement the algorithm in MATLAB with a four-node topology. The result shows that ULP-Strider can provide extra protection and remove 14 % time cost for recovering first-layer content in the scenes of low SNR, while our approach also has better first-layer protection than Strider's codes in high SNR.
