A detailed performance model of the 30 MWe SEGS VI parabolic trough plant was created in the TRNSYS simulation environment using the Solar Thermal Electric Component model library. Both solar and power cycle performance were modeled, but natural gas-fired hybrid operation was not. Good agreement between model predictions and plant measurements was found, with errors usually less than 10%, and t...

The Athena Startup Kit (ask), is an interactive front-end to the Atlas software framework (athena). Written in python, a very effective “glue” language, it is build on top of the, in principle unrelated, code repository, build, configuration, debug, binding, and analysis tools. Ask automates many error-prone tasks that are otherwise left to the end-user, thereby pre-empting a whole category of ...

The article leads to an answer of the research question, whether the developed and implemented regional startup ecosystem model is in line with the elements, principles, objects and iterations of standard knowledge requirements to develop the business environment. In addition the regional ecosystem elements are analyzed in foreign models and the own model is described (the structure, elements, ...

One of the major concerns of electric utilities in installing geothermal power plants is not only the longevity of the steam supply, but also the potential for changes in thermodynamic properties of the resource that might reduce the conversion efficiency of the design plant equipment. Production was initiated at Los Azufres geothermal field with wellhead generators not only to obtain electric ...

This report describes a discrete-time model of the startup phase of a FlexRay network. The startup behaviour of this network is analysed in the presence of several faults. It is shown that in certain cases a faulty node can prevent the network from communicating altogether. One previously unknown scenario is uncovered.

A pacemaker is a small battery operated device that helps the heart to beat in a regular rhythm. It contains a powerful battery, electronic circuits, and computer memory that jointly generate electronic signals. One of the main problems about pacemakers is their batteries. Since the capacity of the batteries is limited, it limits the pacemakers lifetime. The other method to power up the implant...
