Electric vehicles introduce new problems in vehicle route planning. Due to limited battery capacity the fastest route from origin to destination is not always feasible. Existing techniques compute the energy optimal route, however this route is often too conservative in terms of travel time. Optimizing both energy consumption and travel time may allow us to identify routes which are both fast a...

We present a system that automatically generates a cycle-accurate and bit-true instruction level simulator (ILS) and a hardware implementation model given a description of a target processor. An ILS can be used to obtain a cycle count for a given program running on the target architecture, while the cycle length, die size, and power consumption can be obtained from the hardware implementation m...

Recent evolutions on forging process induce more complex shape on forging die. These evolutions, combined with High Speed Machining (HSM) process of forging die lead to important increase in time for machining preparation. In this context, an original approach for generating machining process based on machining knowledge is proposed in this paper. The core of this approach is to decompose a CAD...

Silicon complexity places long-stand paradigms at risk. Key concerns include increasing process variations, defect rates, infant mortality rates, and susceptibility to internal and external noises. These trends are likely to decrease functional yield. Fabrication of die with 100%working transistors and interconnections becomes prohibitively expensive. This paper examines the size and the positi...

At the AAAI 2005 Robot Exhibition, the robot GRACE (Graduate Robot Attending a ConferencE, Fig. 1) will be playing a game that involves human-robot social interaction, navigation, and interface design. The task is for Grace to locate and rendezvous with one of our team members, who will be wearing a pink hat. The game can be seen as a social version of “tag” or “Marco Polo,” where the the robot...

3-Axis Machines have traditionally been used for stamping die insert machining, which have less flexibility in terms of degrees of freedom. In order to cater to ever increasing demand for class-A surface finish of the inserts, additional operations such as hand grinding and polishing needs to be performed. It has been possible to manufacture the die inserts with 5 -axis machines, which in theor...

Timing the transition of a processor design to a new technology poses a provocative tradeoff. On the one hand, transitioning as early as possible offers a significant competitive advantage, by bringing improved designs to market early. On the other hand, an aggressive strategy may prove to be unprofitable, due to the low manufacturing yield of a technology that has not had time to mature. We pr...

Software altert relativ zu ihrer Umgebung. Denn die Umgebung, in der Software eingesetzt wird, verändert sich kontinuierlich. Sowohl die Anforderungen an die Software als auch die verwendete Hardware und Infrastruktur sind einem stetigen Wandel ausgesetzt. Wird die Software nicht entsprechend weiterentwickelt, so altert sie rasch relativ zu ihrer Umgebung. Dieses Problem ist vor allem im Bereic...

The power density in high performance systems continues to rise with every process technology generation, thereby increasing the operating temperature and creating ‘hot spots’ on the die. As a result, the performance, reliability and power consumption of the system degrade. To avoid these ‘hot spots’, ‘temperature-aware’ design has become a must. For low-power embedded systems though, it is not...

Neue Medien und Neue Technologien schaffen die technischen Grundlagen für einen breiten Einsatz visuell-orientierter Unterrichtsmaterialien und für die Integration interaktiver Komponenten in den Lernprozess. Java-Applets, die gerade die Potentiale kombinieren, sind deshalb von herausragender Bedeutung für anspruchsvolle eLearning-Umgebungen. Für die mathematische Ausbildung spielen Interaktivi...
