In this paper, we propose a novel method to measure the distance between two Gaussian Mixture Models. The proposed distance measure is based on the minimum cost that must paid to transform from one Gaussian Mixture Model into the other. We parameterize the components of a Gaussian Mixture Model which are Gaussian probability density functions (pdf) as positive definite lower triangular transformation matrices. Then we identify that Gaussian pdfs form a Lie group. Based on Lie group theory, the geodesic length can be used to measure the minimum cost that must paid to transform from one Gaussian pdf into the other. Combining geodesic length with the earth mover's distance, we propose the Lie group earth mover's distance for Gaussian Mixture Models. We test our distance measure in image retrieval. The experimental results indicate that our distance measure is more effective than other measures including the Kullback-Liebler divergence. Copyright 2009 ACM.

In the Service Oriented grid, a grid application can be composed of diverse grid Services which may be already deployed on grid sites, and dependencies between these grid Services can be described as the workflow graph. Though many grid scheduling methods have been developed, they have been studied based on static heterogeneous computing environment. For this reason, these heuristics cannot be directly applied to grid, which is more dynamic computing environment. Therefore, we develop the dynamic service scheduling method, which support that the workflow applications can be performed effectively in spite of dynamic grid nature. Lastly, we show that our proposed scheduling method outperforms than other conventional scheduling methods through the various experiments. © 2007 IEEE.

Data replication is one of the key components in data grid architecture as it enhances data access and reliability and minimises the cost of data transmission. In this paper, we address the problem of reducing the overheads of the replication mechanisms that drive the data management components of a data grid. We propose an approach that extends the resource broker with policies that factor in user quality of service as well as service costs when replicating and transferring data. A realistic model of the data grid was created to simulate and explore the performance of the proposed policy. The policy displayed an effective means of improving the performance of the grid network traffic and is indicated by the improvement of speed and cost of transfers by brokers. © 2006 IEEE.

Recently, grid computing environment has being changed to the service-oriented grid integrated with Web Services for supporting more open, scalab.e and flexible grid architecture. In this architecture, a grid application is the service-oriented grid application in which grid Services are executed according to the workflow of the grid application. This implies that the grid scheduling method needs to consider grid service characteristics. Although many grid scheduling methods have been developed, we need new grid scheduling method to reflect the service-oriented grid concept and to ensure performance of the grid application. Therefore, we propose the grid service performance model based on factors such as service availab.lity, accessibility, reliability, throughput, and slowdown, and develop grid scheduling method to increase performance of the service-oriented grid application. © 2006 IEEE.

In this paper, we present a grid computing platform that provides experimental scientists and analysts with access to computational simulations and knowledge databases hosted in separate lab.ratories around the world involved with human and animal kidney research. No single lab.ratory can develop these resources in isolation and the community of users should no longer need to be dependent upon the specific programming environment in which applications have been developed. This is a major innovation in life science and exploits the power of existing and planned high-bandwidth communications networks for collab.rative research and for shared access to knowledge resources. The innovation is developed within a specialist community of renal scientists but will be transferable to any other field of research requiring interaction between published literature and databases, theoretical models and simulations and the formulation of effective experimental design. © 2006 ACM.

The aim of the @neurIST project is to create an IT infrastructure for the management of all processes linked to research, diagnosis and treatment development for complex and multi-factorial diseases. The IT infrastructure will be developed for one such disease, cerebral aneurysm and subarachnoid haemorrhage, but its core technologies will be transferable to meet the needs of other medical areas. Since the IT infrastructure for @neurIST will need to encompass data repositories, computational analysis services and information systems handling multi-scale, multi-modal information at distributed sites, the natural basis for the IT infrastructure is a grid Service middleware. The project will adopt a service-oriented architecture because it aims to provide a system addressing the needs of medical researchers, clinicians and health care specialists (and their IT providers/systems) and medical supplier/consulting industries. © 2006 The authors.

Computational grids are emerging as a new infrastructure for Internet-based parallel and distributed computing. They enable the sharing, exchange, discovery, and aggregation of resources distributed across multiple administrative domains, organizations and enterprises. To accomplish this, grids need infrastructure that supports various services: security, uniform access, resource management, scheduling, application composition, computational economy, and accounting. Although several initiatives are engaged in the development of grid technologies, grid accounting issues are yet to be addressed. To overcome this limitation, we propose a new infrastructure called gridBank that provides services for accounting. The support of computational economy and accounting services can lead to a self-regulated accountability in grid computing. This paper presents requirements of grid accounting and different economic models within which it can operate and proposes a grid Accounting Services Architecture to meet them. The paper highlights implementation issues with a detailed discussion on the format for various records/databases that the gridBank needs to maintain. It also presents protocols for interaction between the gridBank and various components within grid computing environments.
