Polymer emulsion containing hydroxyl groups were prepared via soap-free emulsion copolymersion of Styrene(St) and 2-hydroxyethyl methacrylate(HEMA).Effects of HEMA on the reaction rate and monomer conversion as well as particles morphology were *** indicated that HEMA was favorable for enhancing the reaction rate but hardly influenced the final monomer *** the amount of HEMA increased from 5 mol%to 20 mol%,the particles turned from regular spheres to raspberry-like spheres due to phase separation.

We consider a broadcast scenario where one transmitter communicates with two receivers under quality-of-service constraints. The transmitter initially employs superposition coding strategies with arbitrarily distributed signals and sends data to both receivers. Regarding the channel state conditions, the receivers perform successive interference cancellation to decode their own data. We express the effective capacity region that provides the maximum allowable sustainable data arrival rate region at the transmitter buffer or buffers. Given an average transmission power limit, we provide a two-step approach to obtain the optimal power allocation policies that maximize the effective capacity region. Then, we characterize the optimal decoding regions at the receivers in the space spanned by the channel fading power values. We finally substantiate our results with numerical presentations.
We propose a graph convolution-based disentanglement algorithm that is well-performed in the task of cross-modal person re-identification between visible and infrared images. Given the image of an individual in one mo...

This paper investigates an optimal steering control method for the articulated body mobile robot KORYU-II (KR-II), considering energy consumption and trajectory tracking performance as the optimization criteria. The computer simulations of the basic control methods of KR-II's /spl theta/ axis (bending motion between the segments) and s axis (rotation motion of the wheels), lead to the conclusion that the best methods are: the "/spl theta/2 method" combined with the "/spl theta/4 method" for the /spl theta/ axis, and the "s3 method" for the s axis. The "/spl theta/2 method" takes the moving average value of the foremost segment's control angle /spl theta//sub 0/ over a traveled distance L (intersegment length) as the next segment command /spl theta//sub 1/ and then shifts /spl theta//sub 1/ to the following segments according to the moved distance. The "/spl theta/4 method" entails setting a small position control gain for the /spl theta/ axis. The "s3 method" controls the forward velocity of the robot by equally distributed torque commands for all wheels. The experiments by the mechanical model KR-II demonstrated that the introduced control greatly reduces the energy consumption and produces very smooth locomotion; although the trajectory tracking performance is somewhat deteriorated.< >

In this paper a new diagnosis method for scan designs with many scan-paths based on error correcting linear block codes with N information bits and K control bits is proposed, where N is the number of scan-paths. The new approach can be implemented on a modified STUMPS-architecture. In diagnosis mode the test has K times to be repeated In the K repetitions of the test the outputs of the scan-paths are connected to a configurable signature register (with disconnected feedback logic) according to the coefficients of the K syndrome equations of the code. By monitoring the one-dimensional output sequence of the configurable signature register the failing scan-cells in the different scan-paths can be identified with the resolution of the selected error correcting code. Since for the relevant codes, e.g.(shortened) Hamming codes, T-error correcting BCH-code, the ratio K/N decreases very fast with an increasing number N the method is useful for a large number of scan-paths.
