In current day microprocessors, exponentially increasing power densities, leakage, cooling costs, and reliability concerns have resulted in temperature becoming a first class design constraint like performance and power. Hence, virtually every high performance microprocessor uses a combination of an elaborate thermal package and some form of Dynamic Thermal Management (DTM) scheme that adaptive...

Concurrent execution of multiple operations in a single clock cycle of a hardware design may increase its peak power which can lead to cooling, packaging and reliability issues. In this paper, we consider a model of computation based on high-level atomic transactions which has been shown to synthesize hardware designs comparable to hand-written Verilog in terms of area and latency. In hardware ...

This paper introduces a new approach for scheduling security constraint unit commitment (SCUC) including wind farms. Because of uncertainty in wind power production, we tried to develop a new method for incorporating wind power generation in power plant scheduling. For this, wind power generation modeled with unit commitment in a non-linear optimization problem and simulated by submitting diffe...

Electronic devices steadily penetrate almost every area of life and transform our surrounding more and more into a dense heterogeneous wireless network. To enable the potential of such a network, a wireless technology with high scalability potential is required supporting devices with ultra low power consumption as well as high data rates. Ultra wideband (UWB) is a promising technology inherent...

Database engines often consume significant power during query processing activities especially during complex query processing, which is motivating researchers to investigate the redesign of their database internals to minimize the energy overheads. While the prior literature has dealt exclusively with average power considerations, our focus here is on peak power consumption. We begin by profil...

Thermal effects are becoming increasingly important during integrated circuit design. Thermal characteristics influence reliability, power consumption, cooling costs, and performance. It is necessary to consider thermal effects during all levels of the design process, from the architectural level to the physical level. This is challenging because design-time temperature prediction requires acce...

The capacity of the multiple-input single-output (MISO) free-space optical channel with a per-antenna peakpower constraint and a sum (over all antennas) average-power constraint is studied. The asymptotic low-signal-to-noise-ratio (low-SNR) capacity is determined exactly and close upper and lower bounds are presented in the lowand moderate-SNR regimes. The asymptotic low-SNR limit is achieved b...

We have studied bounds on the neutrino mass using new data from the Sloan Digital Sky Survey measurement of the baryon acoustic peak. We find that even in models with a running spectral index where the number of neutrinos and the dark energy equation of state are allowed to vary, the bound on the sum of neutrino masses is robustly below 0.5 eV. Using the SDSS Lyman-α constraint on the amplitude...
