Today’s workflow management systems have problems dealing with both ad-hoc changes and evolutionary changes. As a result, the workflow management system is not used to support dynamically changing workflow processes or the workflow process is supported in a rigid manner, i.e., changes are not allowed or handled outside of the workflow management system. This paper addresses two notorious proble...

The engine speed is one of the most important signals in the engine management system of a combustion engine. The signal is used to control the fuel injection, estimate the engine torque, and to generate reference values. Combustions in the cylinders result in the engine speed oscillating around a momentary average, and many applications are depending on stable estimates of this average engine ...

Finding relevant content is one of the core activities of users interacting with a content repository, be it knowledge workers using an organizational knowledge management system at a workplace or self-regulated learners collaborating in a learning environment. Due to the number of content items stored in such repositories potentially reaching millions or more, and quickly increasing, for the u...

introduction: information management system is a formal approach to collect the necessary information in its due time for managers to facilitate decision-making, planning and management. medical records system which is closely associated with pieces of information and their true value can play an important role in health care organizations. the main objective of this study is to compare informa...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

Successful retrieval of relevant images from large-scale image collections is one of the current problems in the field of data management. In this paper, I propose a system which combines traditional CBIR techniques, such as feature extraction, with a thesaurus for objects / shapes. A brief presentation of the problem area is given, along with the basics of a prototype system, the VORTEX engine.

The paper presents a method for designing a production process simulation system using workflow management technique, which consists of three parts: process model, organization resource model and workflow engine. Based on this method, we put forward a production process simulation system structure, and discuss the function of the key modules in detail. At last we present a sample in practical a...

in this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in xu7/l3 engine. in this study, considering the strength and accuracy of simulation gt-power software in researches on the internal combustion engine...

Traditional Workflow Management Systems (WfMS) is hard to meet the requirements of the dynamic, flexible modern business process. In recent years, Web services technology has been developing. It’s not only makes the activity in workflow by Web services form, but also workflow itself is invoked by Web services, especially semantic web services technology is developing, which makes it possible to...

In this research, vibration control of national engine (EF7) using active mounts is studied for two different mounting layouts. The first layout is based on the current engine mounting of national engine (system of three passive mounts), but the hydraulic mount is substituted by an active mount. The other mounting layout contains 4 mounts, 2 of which are active ones and the others are passive m...
