The work reported here presents a methodology based on a two-fluid model to assess the degree of influence of various geometric and control features of an urban network on the quality of traffic service. The two-fluid model gives a curvilinear relation between the trip time and stop time per unit distance and its parameters characterize the quality of traffic service in urban networks. Any Chan...

Change management is critical and challenging in the development and maintenance of service-based applications and information systems due to the distributed and dynamic nature of services. This paper proposes an approach for facilitating the change impact analysis in a service oriented environment. This research focuses on a typical scenario that multiple services are supported by a single bus...

The goal of the Nexus Event Service is to detect state change in services including the distributed Nexus Location Service. So far only state change on an isolated location service node can be detected. This work presents a model for distributed observation of events tailored to Nexus. With this model state change in a distributed set of location service nodes can be detected.

Background: Extreme weather and climate events such as super typhoons and unprecedented recorded high intensity rainfall events have increased in recent years due to climate change. Such extreme weather events generate floods and cause loss of life and property. Therefore, efficient strategies and measures for flood mitigation and prevention are essential. Computer-aided techniques can increase...

Enterprises are constantly in motion. Novel technologies, new markets opportunities, cost reduction, process improvement, service innovation, globalisation, mergers, acquisitions, etc., continuously trigger enterprises to change. This variety of change drivers also fuels the need for enterprises to seek the right balance between the many, quite often contradicting, drivers for change. In this p...

Urban development significantly changes constructed land across both urban and rural areas around the world in recent years. It is vital to keep constructed land data "fresh" for its application and development. Change detection with remotely sensed imagery is an effective way to updating land cover in large area. In this paper, the updating requirements of constructed land in large area are an...

A transition from a product or technology oriented software company to a service-oriented company with a systematic IT service management is a major change that causes headache for many quality managers. Unfortunately often, this change is seen as a massive tool project but customers and staff are forgotten during the change. In this study, we aim at creating a service management framework that...

a quasi experimental study was made to determine the effect of in-service education on knowledge, attitude and behavior for controlling hospital infections among nurses aids working in teaching hospitals supervised by the ministry of medical sciences and health care services (tehran,1994).   the sample consisted of 75 randomly selected nurses aids who answered the pre and post in service educat...

Detecting motion-based video change, such as different types of motion video or applications using different change detection algorithms in a Web system, is difficult. This paper designs and implements architecture for a real-time or near real-time on-demand motion video change detection system using the Sensor Observation Service (SOS) and the Web Processing Service (WPS) in the Sensor Web env...
