Transient effects of weaning on the health of newly weaning piglets
hematological traits serum biochemical indexes enzyme immune
2016/2/23
The transient effects of weaning on the health of newly weaning piglets were investigated. In this study, 24 piglets were randomly assigned to weaning and suckling (control) groups. Weaning piglets we...
Transient Performance Analysis of a Multicorrelator Signal Quality Monitor
Transient Performance Analysis Multicorrelator Signal Quality Monitor
2015/6/29
The ability to monitor and detect problematic distortions in the received GPS-SPS signal is a task of critical importance. Detection of these satellite signal anomalies or “evil waveforms” (EWFs) can ...
On Detection, Analysis and Characterization of Transient and Parametric Failures in Nano-scale CMOS VLSI
Automatic Test Pattern Generation Crosstalk Design-for-Testability Integrated Circuit Intermittent Failure Soft Error
2014/11/7
As we move deep into nanometer regime of CMOS VLSI (45nm node and below), the device noise margin gets sharply eroded because of continuous lowering of device threshold voltage together with ever incr...
Power Distribution Network Reconfiguration for Bounded Transient Power Loss
Line Power Loss, Loss Reduction, Network Reconfiguration, Transient Power Loss, Transient Stability
2012/12/4
We revisit the loss reduction problem for network reconfiguration in power distribution systems in this paper. Besides the conventional line power loss (LPL), in our model, we introduce a new concept ...
The so-called symmetric H Hs state has been reported to have submillisecond response times, which results from the symmetric profile of the liquid crystal director; however, no direct evidence has b...
Transient behavior of the thermocapillary migration of drops under the influence of deformation
Transient behavior the thermocapillary migration the influence of deformation Fluid Dynamics
2011/8/2
Abstract: The transient thermocapillary migration of drops with nontrivial deformation is studied. The finite difference method is employed to solve the incompressible Navier-Stokes equations coupled ...
Less than 0.19-dB Transient Gain Excursion AGC-EDFA with Digital Control for 20-Channel Add/Drop Equivalent Operation
Transient Gain Excursion AGC-EDFA Digital Control 20-Channel Add/Drop
2015/5/20
We have developed a digitally controlled AGC-EDFA by combining an FF-controlled pump-LD and an FB-controlled VOA. An FPGA is used to finely tune the gain setting of the pump current with a wide dynami...
Life Prediction Based on Transient Dynamics Analysis of Van Semi-trailer with Air Suspension System
van-body air suspension system transient dynamics
2011/8/4
The early fatigue damage in the van-body of the semi-trailer is often caused by the unique mechanical characteristics and the dynamic impact of the loads. The traditional finite element method with st...
Inverse transient quasi-static thermal stresses in a thin rectangular plate
Thin rectangular plate inverse transient quasi-static thermal stress
2010/11/25
In this paper the solution of inverse transient quasi-static thermal stresses in a thin rectangular plate occupying the space –a ≤ x ≤ a , -b ≤ y ≤ b has been determined. The expression of the tempera...

This article makes a mathematical analysis of transient rotating flow of an incompressible second grade fluid in a porous medium. The flow motion in the model is induced by a given but arbitrary inlet...
汽油机HCCI燃烧过渡过程控制策略（Transient Operation Strategy of Gasoline HCCI Engine）
HCCI燃烧 过渡工况 对称性原则
2009/12/28
利用可变气门机构使部分残余废气留在缸内，是实现汽油机HCCI燃烧的切实可行的方法，然而多气门参数的调节又给燃烧控制增加了难度。本文通过试验，研究了全可变气门机构中4个控制变量对汽油机HCCI燃烧过程的影响，并对过渡过程中发动机负荷相对于各控制变量的动态响应时间进行了比较。研究发现，实现HCCI燃烧过渡过程的快速响应，应当采用适当的控制参数的耦合策略。试验结果表明，进、排气门相位的对称性原则和气门升...
