Shrinking reserves of natural resources as well as incisive environmental pollution oblige humanity to rethink its generally favored propulsion concept: in the last decade electro-mobility as a refurbished technology gained greater significance once more. Due to political course setting, many German cities are testing Electric Vehicles (EV) especially in public bus transport. To get to the bottom...
The energy costs for cooling a data center constitute a significant portion of the overall running costs. Thermal imbalance and hot spots that arise due to imbalanced workloads lead to significant wasted cooling effort - in order to ensure that no equipment is operating above a certain temperature, the data center may be cooled more than necessary. Therefore it is desirable to schedule the workload...
A simulated annealing framework is presented for learning gene regulatory networks with predefined attractors, under the threshold Boolean network model updated sequentially. The proposed method is used to study the robustness of the networks, defined as the number of different updating sequences they can have without loosing the attractor. The results suggests a power law between the frequency of...
Coiling temperature is one of the most important targets of hot strip rolling. The coiling temperature can be controlled by laminar cooling system. A lot of measured data were got by many experiments in considering of the characteristics of hot strip rolling and the strip temperature change characteristics in laminar cooling area. To overcome the defects of traditional model, a new coiling temperature...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
The Solar Decathlon is a competition to design, build and operate the most effective and attractive house powered solely by the Sun. The U.S. Department of Energy proudly sponsors the international competition for college level students. The competition is designed to showcase "energy we can live with", meaning solar and energy efficiency technologies that are not only viable today, but...
