During these last decades, air pollution has drawn the attention of scientists because of the deterioration of the human environment that it has caused. Unfortunately, the study of this dynamic phenomenon is very complex and requires the use of models that ...
We present a method for calcg. multidimensional free energy surfaces within the limited time scale of a first-principles mol. dynamics scheme. The sampling efficiency is enhanced using selected terms of a classical force field as a bias potential. This sim ...
This paper presents a micropower second-order low-pass filter using the log-domain principle and integrated in a 0.35-μm CMOS process. It has been designed as an antialiasing filter for a DECT transceiver with a 45-kHz nominal cutoff frequency. The circuit ...
The paper develops a leakage-based adaptive algorithm, referred to as circular-leaky, which in addition to solving the drift problem of the classical least mean squares (LMS) adaptive algorithm, it also avoids the bias problem that is created by the standa ...
From lidar signals detected with a shot/shot differential absorption lidar instrument tuned for tropospheric O3 measurements and recording each individual return, histograms of their sampled values for each channel of their digitizers were reconstructed. A ...
We propose a modified leaky-LMS filter that ensures stability of the estimates w(k) in the presence of bounded noise, without introducing any bias term and with the added cost of only a comparison and a multiplication per iteration when compared to the cla ...
We report on the growth of barrier, reservoir and quantum well electron transfer (BRAQWET) structures using chemical beam epitaxy. The photoluminescence spectra of the structures are affected by the bias voltage. The QW emission line is extinguished at pos ...
We investigated the I-V characteristics of the double barrier stair-well structure. Resonant tunneling current is achieved by application of an electric field, which increases the transmission under positive bias and decreases it under the reverse bias. Th ...
In this Article, a review is presented of recent developments in Monte Carlo simulations of chain molecules. The Rosenbluth chain insertion technique is used to calculate the free energy of the chain molecules. Furthermore, this insertion method is used to ...
Some of the fundamental problems concerning nanocryst. film electrodes such as photocurrent and photovoltage generation, the effect of an external bias, and the importance of surface states were discussed. The problems were described from a mol. perspectiv ...
