– Development of information systems for the management of complex organisational structures is a well known problem, it is interesting in particular in presence of many figures with different roles that interact with the system. Traditionally the development of an information system includes a phase of analysis of the requirements, a phase of analysis of the existing system (independently from...

The close control of building services is seen as essential component for delivering low energy performance. This inevitably means some form of supervisory control and data acquisition (SCADA) system. To increase the penetration of this technology into the market place, it is inevitable that internet communication will be employed increasingly in the future. However, it can be very challenging ...

This research focuses on the development of a rule-based intelligent equipment trouble-shooting and maintenance platform using JAVA Expert System Shell (JESS) technology. A prototype system is designed and developed combining rule-based knowledge system and inference engine to support real-time collaborative equipment maintenance across geographical boundary. The main modules of the system incl...

The power management controller of a hybrid vehicle orchestrates the operation of onboard energy sources, namely engine and auxiliary power source with the goal of maximizing performance objectives such as the fuel economy. The paper focuses on optimization of the power management strategy of the refuse truck with parallel hydraulic hybrid powertrain. The high power density of hydraulic compone...

Development of robust and highly sensitive algorithms for detecting incipient bearing faults in gas turbine engines will greatly benefit both military and civil aviation through improved aircraft reliability and maintainability. Techniques including advanced vibration analysis and oil debris monitoring have proven effective in laboratory and industrial settings, but factors including poor trans...

GridSpace Engine is the central operational unit of the ViroLab Virtual Laboratory. This specific runtime environment enables access to computational and data resources by coordinating execution of experiments written in the Ruby programming language extended with virtual laboratory capabilities. Experiments harness published and semantically described services which constitute a GridSpace. The...

basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. an efficient approach to studying cooling system for diesel engine is a 3d computational fluid dynami...

in internal combustion engines, only about a third of the total fuel input energy is converted into useful work. if the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. the main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing cerium...

introduction: voluntary counseling and testing (vct) for hiv infection is a confidential service offered to individuals in the community. this study intended to present a pattern for regional surveillance of vct services in iran. methods: this was an applied descriptive study. at first, the existing regional vct surveillance in 2009 was investigated through visiting the clinical deputy of medic...

Work Integrated Learning (WIL) is widely acknowledged as providing an excellent complement to academic study in vocational degree programs such as construction management. However, the current context of higher education, with its increasing enrolment numbers and tightening of available resources, makes the delivery of effective WIL quite problematic. One key element of WIL is the situated natu...
