We consider the energy efficiency of error correction mechanisms on a system consisting of a generalpurpose processor and a wireless interface. Since high error rates are inevitable to the wireless environment, energy efficient error control is an important issue for mobile computing systems. We will show that it is not sufficient to concentrate on the energy efficiency of error control mechani...

Energy-corrected finite element methods provide an attractive technique to deal with elliptic problems in domains with re-entrant corners. Optimal convergence rates in weighted L2-norms can be fully recovered by a local modification of the stiffness matrix at the re-entrant corner, and no pollution effect occurs. Although the existence of optimal correction factors is established, it remains op...

Self-consistent calculations using the Perdew-Zunger self-interaction correction (PZ-SIC) to local density and gradient dependent energy functionals are presented for the binding energy and equilibrium geometry of small molecules as well as energy barriers of reactions. The effect of the correction is to reduce binding energy and bond lengths and increase activation energy barriers when bond br...

A much improved determination of the transverse energy of jets has been carried out in ZEUS, using a correction procedure based on two independent methods. The first is based on a combination of tracking and calorimeter information which optimises the resolution of reconstructed kinematic variables. The conservation of energy and momentum in neutral current deep inelastic ep scattering events i...

Introduction: Photon attenuation in tissues is the primary physical degrading factor limiting both visual qualitative interpretation and quantitative analysis capabilities of reconstructed Single Photon Emission Computed Tomography (SPECT) images. The aim of present study was to investigate the effect of attenuation correction on the detection of activation foci following statistical analysis w...

.?? The Casimir energy, the quantum correction part of the energy, of a class of space-dependent scalar field configurations is examined in a Coleman-Weinberg type Xd4-theory in the d-dimensional regularization scheme. For the cases when the scalar ) field is dependent on only one space-coordinate and partially excludes its fluctuations from a region of space, we develop formulae effective for ...

Abstract. We describe atoms by a pseudo-relativistic model that has its origin in the work of Chandrasekhar. We prove that the leading energy correction for heavy atoms, the Scott correction, exists. It turns out to be lower than in the non-relativistic description of atoms. Our proof is valid up to and including the critical coupling constant. It is based on a renormalization of the energy who...

ISGRI, the IBIS low energy camera (15 keV 1 MeV) on board INTEGRAL, is the first large CdTe gamma-ray imager in orbit. We present here an overview of the ISGRI in-flight calibrations performed during the first months after launch. We discuss the stability of the camera as well as the CdTe pixels response under cosmic radiation. The energy calibrations were done using lead and tungsten fluoresce...

intermolecular potential energy surface (ips) for protein — protein has been examined using rhf, dft-b3lypand mp2 levels of theory with 6-31g, 6-31g* basis sets. a number of basis sets were used in order to evaluatethe basis set effects, at all three levels of theory, basis sets has significant effects on the calculated potentialenergy curves (including position, depth and width of the potentia...

The raw bit error rate of NAND Flash memory increases as the semiconductor geometry shrinks for high density, which makes it very necessary to employ a very strong error correction circuit. The soft-decision-based error correction algorithms, such as low-density parity-check (LDPC) codes, can enhance the error correction capability without increasing the number of parity bits. However, soft-dec...
