To address the issue that how the EEG-EMG signals change according to different motion modes, an experiment was conducted on ten subjects with three tasks performing the voluntary, stimulated and imaginary finger flexion activities. The experiment was set two programs including 10s and 2s time intervals. Electroencephalogram (EEG) from C3/C4 channels and electromyogram (EMG) from flexor digitorum superficialis were recorded simultaneously. Besides the threshold detection of wave peaks between two points, morlet wavlet-based time-frequency analysis was adopted to study the independent variation mechanisms between EEG and EMG under different motion modes. The results indicated that EMG signals of 2s intervals exhibited a similar trend with 10s intervals. The EMG energy increased over 50 Hz when actions occurred. On the contrary, there were no significant changes in imaginary task. In addition, EEG signals performed obviously different. No pronounced similar changes were found in 10s and 2s intervals. Finally, the results demonstrated that EEG-EMG causality was high during 2s intervals in stimulation task.

The grain oriented silicon steel containing 3%Si-0.5%Cu was produced by low slab reheating temperature technique. The precipitates were observed during the mainly process such as hot rolling, normalization, primary and secondary recrystallization annealing. The species, size, density and shape of precipitates were identified using TEM technique. The results indicate that Cu2S and AlN are mainly inhibitors which precipitate during hot rolling and normalization respectively. After primary recrystallization annealing the precipitation size of Cu2S is in the range of 30~40nm while the mean size of AlN is ~50nm, which could inhibit grain growth. In addition, the precipitation of MnS is inhibited comparing with the precipitation of Cu2S.

Molecular dynamics simulation method is used to study the effect of NH4Cl on the properties of Lewis acidic 1-ethyl-3-methyl-imidazolium chloride/chloroaluminate molten salts (molar ratio1:2) at the 300K. The dynamics and physical chemical properties such as diffusion coefficients, viscosity, conductivity of Lewis acidic [EmiCl/AlCl3(molar ratio1:2) with different molar fraction of NH4Cl are calculated. It is shown that the density increases firstly and reduces afterward, the conductivity decreases and viscosity increases with increasing of NH4Cl content. The self-diffusion coefficient of [Emi+, NH4+, Cl-and AlCl3reduces, and the trend to AlCl3self-diffusion is the most obvious.

Published: September 2013

With the realization of physical memristors, using memristors to perform stateful logic operations has been demonstrated feasible. In such operations, memristors simultaneously serve as latches and logic gates, thus enabling the in-situ computing which may open a new computing paradigm for computer architecture. In this paper, we first analyze two types of typical memristive stateful logic gates to reveal the working mechanism of the stateful logic, and then review the recent researches on the memristive stateful logic, and finally discuss the pros and cons of the stateful logic. We reach the conclusion that the stateful logic promises a novel computing paradigm which may revolutionize the conventional computer architecture, while its development is currently subjected to the state drift problem and is constrained by the lack of a general design methodology and physically verification.

Designers are increasingly relying on FPGA-based emulation to evaluate the performance of LDPC codes. In this paper, we propose a novel approximate lower triangular structure for the parity part of the parity-check matrix of QC-LDPC codes. Next, a high speed partially parallel decoder architecture which based on the Offset BP-based decoding algorithm is proposed. The results indicate that the frequency can reach 100MHz and its throughput rate can reach 113Mbps.

Distributed resources and microgrids may be designed for power supply in some area. AC-DC or DC-AC conversions are required in microgrids because of DC distributed resources, e.g. photovoltaic arrays. In this paper some factors are considered for determining the voltage grades of microgrids, both AC grid and DC grid, according to comprehensive analysis of microgrid design and operation. The factors include microgrid or distributed resource capacity, efficiency, cost, safety and so on. The line length, microgrid capacity and economic impacts are taken into account for selecting the voltage grade to connect the microgrid into the distribution system. Further, suitable AC and DC voltage grades are selected for residential and commercial application with some microgrid cases.

The sintered body of tubular cathode for Direct Ethanol Fuel Cell (DEFC) is prepared by the gelcasting process using a certain proportion of graphite powder and mesocarbon microbead (MCMB). The electrical performance under different air flow rates, operating temperature, porosity of cathode diffusion layer, inlet pressure and different thickness of catalyst layer are analyzed by the combination of experimental and numerical simulation method. The results show that the increase of diffusion layer porosity, inlet pressure, thickness of catalyst layer and operating temperature are benefit for the improvement of the cell performance. Moreover, the electrical performance is improved when the air flow rate is 100 mL/min.

Published: September 2013

CQI(Channel Quality Indicator) is an essential indicator for AMC(Adaptive Modulation and Coding) technique in LTE. Due to the long delay of GEO satellite channel, CQI prediction is necessary to ensure effective AMC. This paper proposes the approximation from real CQI data containing small scale fading to that containing only large scale fading to do prediction. The concrete correlation features and the difference between the approximation and the original data are all analyzed. Simulation is done for confirmation. It shows that the approximate large scale CQI data is feasible and rational for prediction and ensuring AMC efficiency.

Published: September 2013

In LTE(Long Term Evolution) system, scheduling plays an important role in the process of allocating resource. LTE system puts forward semi-persistent scheduling (SPS) for new applications such as VoIP(Voice on Internet Protocol) and online games. Considering the problem of resource collision in SPS HARQ(Hybrid Automatic Repeat reQuest) process, we explore the relationship between uplink semi-persistent scheduling period and the number of semi-persistent transmissions, and propose two novel solutions. One is choosing specific uplink semi-persistent period for different uplink/downlink (UL/DL) configurations and the number of transmissions. The other is delaying collision processes for the configuration of small uplink period. The analysis proves that the two solutions can reduce the collision probability and improve the stability of LTE system.

When this fusion rule fuses the low frequency sub-band resolved by wavelet method, it adequately consider the local areas regional energy and the regional energys similarity of the image which is need to fuse, and it use threshold to choose appropriate fusion rule. Experimental result indicated that this way can preferably keep detail features of the image, and it has some engineering application value.
