An error back propagation （BP） neural network prediction model was established for the shunt current compensation in series resistance spot welding. The input variables for the neural network consist of the resistivity of the material, the thickness of workpiece and the spot spacing, and the shunt rate is outputted. A simplified calculation for the shunt rate was presented based on the feature of the constant-current resistance spot welding and the variation of the resistance in resistance spot welding process, and then the data generated by simplified calculation were used to train and adjust the neural network model. The neural network model proposed was used to predict the shunt rate in the spot welding of 20# mlid steel （in Chinese classification）（in 2. 0 mm thickness） and 10# mild steel （in 1.5 mm and 1.0 mm thickness）. The maximum relative prediction errors are, respectively, 2. 83%, 1.77% and 3.67%. Shunt current compensation experiments were peoCormed based on the neural network prediction model proposed to check the diameter difference of nuggets. Experimental results show that maximum nugget diameter deviation is less than 4% for both 10# and 20# mlid steels with spot spacing of 30 mm and 50 mm.

In this paper, we estimate the influence of random dopants (RDs), interface traps (ITs), and random work functions (WKs) using the experimentally calibrated 3D device simulation on DC characteristic of high-κ / metal gate n- and p-type bulk fin-typed field-effect-transistors. We further study these intrinsic parameter fluctuations' impact on drain induced barrier lowering (DIBL). The main findings of this work show the RDF and WKF on n-type device are larger than that of p-type one. The DIBL is dominated by the number of random dopants.

The paper investigates the performance of a hybrid satellite-terrestrial cooperative network (HSTCN), where some terrestrial amplify-and-forward (AF) relays are employed to assist the signal transmission from a satellite to a destination, which is corrupted by multiple co-channel interferences (CCIs). In this system, the satellite links undergo Shadowing-Rician fading while the terrestrial links experience Rayleigh fading. Specifically, by assuming that maximum ratio combining (MRC) is used at the destination, we first derive the moment generating function (MGF) of the output signal-to-interference-plus-noise ratio (SINR). With the help of MGF, we then present the analytical average symbol error rate (ASER) expression for the considered cooperative system. Moreover, to gain further insights, the asymptotic ASER analysis in terms of the diversity order and array gain is also developed. Finally, numerical results are given to demonstrate the validity of the performance analysis and the impacts of shadowing parameters, relay number and CCIs on the considered HSTCN.

In this paper,we present a model predictive control algorithm for input-saturated systems by a saturation-dependent Lyapunov function *** saturation-dependent Lyapunov function captures the real-time information on the severity of saturation and thus leads to less conservative results in controller design.A set invariance condition for the systems with input saturation is presented.A min-max MPC algorithm is proposed for the linear parameter-varying(LPV) systems based on the invariant *** MPC controller is determined by solving a linear matrix inequality(LMI) optimization *** example demonstrates the effectiveness of the proposed algorithm.

IMART software for correction of motion artifacts in images collected in intravital microscopy

Intravital microscopy is a uniquely powerful tool, providing the ability to characterize cell and organ physiology in the natural context of the intact, living animal. With the recent development of high-resolution microscopy techniques such as confocal and multiphoton microscopy, intravital microscopy can now characterize structures at subcellular resolution and capture events at sub-second temporal resolution. However, realizing the potential for high resolution requires remarkable stability in the tissue. Whereas the rigid structure of the skull facilitates high-resolution imaging of the brain, organs of the viscera are free to move with respiration and heartbeat, requiring additional apparatus for immobilization. In our experience, these methods are variably effective, so that many studies are compromised by residual motion artifacts. Here we demonstrate the use of IMART, a software tool for removing motion artifacts from intravital microscopy images collected in time series or in three dimensions.

This paper analyzes the effect of an indoor frequency selective fading channel, characterized by its power delay profile, on the performance of an asynchronous DS-CDMA system with high transmission rate (50 Mb/s or more). The bit error rate (BER) is determined by the characteristic function method and by Monte-Carlo simulations. The results show that when the rms delay spread is close to the transmitted symbol duration, the system performance degrades considerably and that the performance degradation strongly depends on the maximum delay spread. © 2013 IEEE.

In this work, the planar HKMG MOS devices are fabricated on (100) wafer with p-substrate. To improve the samples' interface roughness between the Si/Ge film and the interface layer, three different clean treatments are considered to fabricate the MOS devices. Among processes, the experiment indicates that HF and water rinse can present hydrogen termination to bond silicon as a good passivation. The measured C-V curves and HRTEM of the fabricated samples show the interface roughness is improved significantly. The extracted shift of flat band voltage (ΔV fb ) and density of interface traps (D it ) have around 50% improvement.
