multidimensional modelling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission and rate of heat rele...

Open Source Software (OSS) developer and end-user communities mutually benefit from, but also depend on each other. End-user communities generate innovative ideas for software, but lack technical capabilities for their realization. OSS developers realize software, but need to access and prioritize an abundance of ideas to maximize impact. Requirements Bazaar, a Web-based tool for Social Require...

Distributing mixed realities in learning environments will open up new possibilities of local and distant cooperation in teaching and learning processes. Some requirements from the new vocational learning field mechatronics will be presented and our approach to meet them in a European Project, DERIVE-Distributed Real and Virtual Learning Environment, is shown.

This paper explores the optimal operation of a distributed ammonia production facility which is coupled with local renewable energy generation. The coupling of stochastic renewables with this flexible chemical process enables exchange of energy with the utility in a highly regulated and benign manner. In particular, we analyze the ability of this facility to operate economically under a market ...

Ad hoc sensor networks are ad hoc networks that are characterized by decentralized structure and ad hoc deployment. Sensor networks have all the basic features of ad hoc networks but to different degrees – for example, much lower mobility and much more stringent energy requirements. We analyze the current state of research and evaluate open issues in development of routing techniques in wireles...

cumin (cuminum cyminum) is an annual suitable for the dry and semi-dry areas of iran. recently, farmers have chosen to plant cumin because it requires less water and growth time. however, at harvest time, the resistance of cumin seed to shatter is low and, if careful attention is not paid to this fact, a major portion of the crop can be lost. when the connection force of the seed decreases, see...

Nutrient density, the vitamin or mineral content of a food or diet per unit energy, has long been a useful concept in the nutritional sciences. However, few nutritionists have applied the idea in quantitative, population-based nutrition planning and assessment. This paper discusses the conceptual issues related to the calculation of a nutrient density value that, if consumed, should meet the nu...
