From the varying threshold voltage of MOSFET caused by the external factor, this paper analyzes the variation tendency of amplifier's gain. It makes clear how the gain of three different amplifiers changes in theoretical. After that, EDA tools are utilized to verify the theoretical calculation. The theoretical and simulation result show that threshold voltage(Vth) is a sensitive parameter of amplifier's...
Face sketch-to-photo synthesis has attracted increasing attention in recent years for its useful applications on both digital entertainment and law enforcement. Although great progress has been made, previous methods only work on face sketches with rich textures which are not easily to obtain. In this paper, we propose a robust algorithm for synthesizing a face photo from a simple line drawing that...
A catalytic combustion type methane gas sensor with Pd-Pt/ γ-Al2O3 catalyst working on pulse voltage mode is investigated in this paper, after fabricated by micromachining and sol-gel process on a silicon substrate. In order to achieve low power consumption as well as high sensitivity, pulse voltage was applied to a bridge circuit consisted of the sensor, and the ratio of the gas sensitivity...
In the development of integrating various heterogeneous wireless access networks, handoff decision is regarded as an important and challenging issue. In this paper, we propose a handoff decision algorithm considering both the link reward of multipath parallel transmission and the handoff cost between different management domains. The model of Markov decision process is used to determine the optimal...
This paper presents the design of a decentralized storage scheme to support multi-dimensional range queries over sensor networks. We build a distributed k-d tree based index structure over sensor network, so as to efficiently map high dimensional event data to a two-dimensional space of sensors while preserving the proximity of events. We propose a dynamic programming based methodology to control...
In protocol engineering area, conformance testing is a very important step. The purpose of conformance testing is to determine to what extent a single implementation of a particular standard conforms to the individual requirements of that standard. The Finite State Machine (FSM) model is usually used in protocol conformance testing. In this paper, an improved FSM-based method is introduced to generate...
