Although self-assembled quantum dots are grown on wetting layers, most simulations exclude the wetting layer. The neglected effects on the electronic structure of a pyramidal InAs quantum dot embedded in a GaAs matrix are investigated based on the effective one electronic band Hamiltonian, the energy and position dependent electron effective mass approximation, and a finite height hard-wall 3D ...

A new approach for estimating Digital Signal Processors’ energy consumption is presented. Our energy consumption model is based on a functional analysis of the DSP’s core. Several consumption rules are determined. They give, from specific parameters extracted from the algorithm’s source code, the consumption of every functional block in the DSP, and lead to the application’s overall energy cons...

Energy level crossings are the landmarks that separate classical from quantum mechanical modeling of molecular systems. They induce non-adiabatic transitions between the otherwise adiabatically decoupled electronic level spaces. This review covers results on the analysis of propagation through level crossings of codimension two, a mathematical justification of surface hopping algorithms, and a ...

Plasmas with multiply charged ions are of great importance for many applications as, e.g., near-electrode phenomena in arcs, pulsed high-current dis­ charges, plasmas produced by wire explosions, shock fronts, high-intensity lasers and ion beams. Let us mention also that the development of X-ray lasers is closely connected with the behaviour of highly ionized plasmas of heavy elements. Most of ...

Power, and consequently energy, has recently attained firstclass system resource status, on par with conventional metrics such as CPU time. To reduce energy consumption, many hardwareand OSlevel solutions have been investigated. However, application-level information which can provide the system with valuable insights unattainable otherwise was only considered in a handful of cases. We introduc...

The body of mobile applications is growing at a near-exponential rate; many applications are increasing in both scale, complexity, and their demand for energy. The energy density of smartphone batteries is increasing at a comparably insignificant rate, and thus inhibits the practicality of these applications. Despite the importance of energy to mobile applications, energy is rarely considered b...

A new method for creating instruction level energy models for pipelined processors is introduced. This method is based on measuring the instantaneous current drawn by the processor during the execution of the instructions. An appropriate instrumentation set up was established for this purpose. According to the proposed method the energy costs (base and inter-instruction costs) are modeled in re...

The change of crowd energy is a fundamental measurement for describing a crowd behavior. In this paper, we present a crowd abnormal detection method based on the change of energy-level distribution. The method can not only reduce the camera perspective effect, but also detect crowd abnormal behavior in time. Pixels in the image are treated as particles, and the optical flow method is adopted to...

introduction: scatter radiation is one of the major sources of error in nuclear medicine data processing. different methods of scatter correction have been introduced in order to improve the quality of data. however the best method is to avoid recording of scatter photons in acquisition. the only difference between scattered and non-scattered photons is the energy. pulse height analyzer is the ...
