Abstract: Reduction of NOX emissions and fuel consumption are the main topics in engine development, forcing the adoption of complex techniques and components, whose interactions have to be clearly understood for proper and reliable operations and management of the whole system. The investigation presented in this paper aimed at the development of integrated control strategies of turbocharging,...

Increasingly stringent international diesel particulate emissions standards have re-established interest in Diesel filters. Modern Diesel engine technology, with computerized engine management systems and advanced, common rail injection systems, needs to be fully exploited in order to allow the application of efficient and durable Diesel filter systems, usually supported by catalytic aids, as s...

Crowd control has become increasingly important in urbanized military operations such as peace keeping, riot control, disaster management, emergency evacuation, and rescue operations. In this paper, we describe an architecture for simulating virtual crowd to aid in the training, planning and decision making process in the area of military operations. Our system makes use of the light-weight age...

During the past decade, much research has been performed in the areas of method engineering and process improvement. As a result of this research, we are developing the online method engine (OME). The OME is a knowledge management system that provides support during process improvement initiatives, using a set of assessments, an extensive method base, and automatic method assembly mechanisms. T...

The AASTINO (Automated Astrophysical Site Testing INternational Observatory) is a remote laboratory that has been operating at Dome C station on the Antarctic plateau since January 2003. It is designed to run throughout the Antarctic winter without intervention, and to collect data on the astronomical qualities of the site. A Stirling engine and a pair of solar panels power the observatory. Com...

nowadays, cad/cam simulation is considered as a strong tool to estimate performance of various systems and to reduce costs and testing time. in this study, we used gt-power software to model the performance of an si engine. the results indicate that the engine power drops significantly as altitude increases. to compensate power loss, the engine is equiped with a turbocharger system. the proper ...

in order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. in this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. two elements have been added to the lubrication circuit in the modified engine. these elements are hydraulic lifters and an anti-drai...

We examine the relationship between context engines and content management systems, showing by means of an example application how these should mutually interact with each other to ensure the timely delivery of relevant information. We show how a content management system can use context information to enrich its functionality and also how a general and abstract approach to content management c...
