Concentrating on the problem of massive energy loss in compressor, expansion valve, and other components present high-temperature heat pump system under extensive temperature lift, dual-flash compound circulation is proposed thermodynamic model was established. The article combines multivariate simulated annealing algorithm, utilizes COP as optimization goal, completes calculation parameters st...

In Jet and Flash Imprint Lithography (JFIL), ambient gas is trapped between the resist, substrate mold. The volume of estimated about 9.7 ~ 21.5% resist volume. It takes time for bubbles to disappear in closed space. By using carbon dioxide as atmospheric applying an organic layer such Spin on Carbon (SOC) top surface substrate, it proposed by theoretical calculation that disappearance shortene...

Abstract—Flash flood is occurred in short time rainfall interval: from 1 hour to 12 hours in small and medium basins. Flash floods typically have two characteristics: large water flow and big flow velocity. Flash flood is occurred at hill valley site (strip of lowland of terrain) in a catchment with large enough distribution area, steep basin slope, and heavy rainfall. The risk of flash floods ...

We present a concise review of the recent theoretical progress concerning the standard model calculation of the inclusive radiative B̄ → Xsγ decay. Particular attention is thereby devoted to the calculations of the next-to-next-to-leading order fixed-order O(αs) contributions, non-local O(αsΛ/mb) power corrections, and logarithmic-enhanced O(αs) cut-effects to the decay rate. The current status ...

The equations of motion for a massive spin2 Rarita-Schwinger field in a finite-range, central, Lorentz scalar potential are developed. It is shown that the resulting density may not be everywhere positive definite.

Delay faults are an increasingly important test challenge. Traditional open and bridge fault models are incomplete because only the functional fault or a subset of delay fault are modeled. In this paper, we propose a circuit level model for resistive open and bridge faults. All possible fault behaviors are illustrated and a general resistive bridge delay calculation method is proposed. The new ...

Laptop computers and tablet PCs currently exploit swap system with their second storage media as a cost effective solution to extend limited memory space. The rapidly evolving flash memory technology starts to replace the magnetic disks of these computers by flash memory due to its advantageous characteristics such as energy efficiency and mechanical shock resistance. Thus, we can imagine that ...

This chapter is to introduce NAND flash channel model, error correction codes (ECC) and signal processing techniques in flash memory. There are several kinds of noise sources in flash memory, such as random-telegraph noise, retention process, inter-cell interference, background pattern noise, and read/program disturb, etc. Such noise sources reduce the storage reliability of flash memory signif...
