the automatic assignment of protein secondary structure from three dimensional coordinates is an essentialstep in the characterization of protein structure.although, the recognition of secondary structures suchas alpha-helices and beta-sheets seem straightforward, but there are many different definitions, eachregarding different criteria. we have developed a newalgorithm for protein helix assig...

The mold-filling behavior in the casting of aluminum alloy (A413) using lost foam casting (LFC) was explored. The effects of gate numbers, type of gating and casting thickness on the filling behavior were evaluated. Although, unlike convectional casting process, the gating system showed little effect onfilling ability, casting thickness created a greater effect on the mold filling. In contrast ...

grapes are among the world most planted horticultural crops. since the last century, attempts have been made to improve the quality of grapes in the world. meanwhile, the necessity of having knowledge about the history of progenies families led to the link between genealogy and breeding. considering some previous mislabeling, in order to find out the accuracy of the controlled crosses as well a...

Objective: Different categories are available for estimating of radiation dose. Radioisotopes with the same energy and almost the same physical properties have similar effects. Monte Carlo technique is a computerized method based on mathematical simulation of physical processes. The main purpose of this study is to show that beta particles are not able to penetrate deep into the water. also dif...

This work investigates the channel thickness dependency of high-k gate dielectric-based complementary metal-oxide-semiconductor (CMOS) inverter circuit built using a conventional double-gate metal gate oxide semiconductor field-effect transistor (DG-MOSFET). It is espied that the use of high-k dielectric as a gate oxide in n/p DG-MOSFET based CMOS inverter results in a high noise margin as well...

In this paper, we propose a novel method for fast and effective gate-sizing and multiple Vt assignment using Lagrangian Relaxation (LR) and posynomial modeling. Our algorithm optimizes a circuit’s delay and power consumption subject to slew rate constraints, and can readily take process variation into account. We first use SPICE to generate accurate delay and power models in posynomial form for...

High-assurance systems, such as flight control and banking systems require strict guarantees on information flows or else face catastrophic consequences. Information flow tracking (IFT) is a frequently used security measure for preventing unintended information flows in such systems. Recently, Gate Level Information Flow Tracking (GLIFT) has been proposed to track information flows at the hardw...

The current ultrasound therapy machines are implementing continuous waveform, which in fact, is not an optimum technique for therapy treatment process. Apparently, pulse waveform appearing as a more effectively way of signal generation in terms of its power consumption, low cost hardware and short timing used. In order to overcome these drawbacks of conventional therapy machines, we proposed a ...
