This article demonstrates the feasibility of converting Iran’s 40MWt heavy-water research reactor at Arak (the IR-40) to use low-enriched uranium fuel in order to slow the production of weapon-usable plutonium. Two methods are proposed, and both retain identical power density, thermal-hydraulic, and safety profiles as the original design and require no physical alteration of the core. They can ...

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, ...

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...
