In order to achieve integration of electrmotion and manual operation for manual forklift, this paper designs an improved manual forklift. We select the appropriate motor according to parameters of original manual forklift, which was analyzed by SolidWorks. We make the detailed design of the speed reducer according to the selected motor＇s rated speed and other parameters, and design the reduction speed ratio, reduction speed form, size of gear drive, meshing parameters, force analysis of gear and strength check. In this paper, we electrify the traditional manual forklift eventually.

The decomposition methods of surface electromyogram (SEMG) signals are mainly based on independent component analysis, blind source separation and the neural network. Because actual signals are the decomposition faced to single-guide signals, so the neural network decomposition method has more advantage. In this paper, we improve the composition of neural network based on the generation principle and decomposition significance of SEMG, and use this network to decompose the signal and to obtain a higher accuracy through the experimental data above. Beside, under medium-low shrinkage level the decomposition algorithm can successfully extract the dissemination information of motor unit action potentials in SEMG. © 2015 SERSC.

The aim of software safety assessment is to evaluate whether the software meets the safety requirements, and this measurement is very important to ensure and confirm the software safety. This paper presents a new software safety assessment method that is based on the combination of frequency analysis and Analytic Hierarchy Process. First, use frequency analysis method to select some appropriate assessment indicators; then use the Analytic Hierarchy Process to construct the assessment system and assign suitable weight values to indicators at all layers of system; finally rate the software safety. Through the example analysis, it is proved that this method can evaluate software safety very well.

Text Categorization plays an important role in the fields of information retrieval, machine learning, natural language processing, data mining and others. With the development of computer and information technology, there have been many classification algorithms. Each text classification algorithms will get result at differing speeds and efficiency due to the various feature of test text. It has been found that Naive Bayes classifier has a higher accuracy and rate by classifying Movie Reviews in NLTK using Decision Tree classifier, Naive Bayes classifier, Maximum Entropy classifier and K-nearest neighbor classifier.

Firearm suppressors reduce the muzzle blast of a gunshot through a series of baffles contained in a canister. The American National Standards Institute has no firearm suppressor testing standards. A recent NATO test standard, AEP 4875, ignores the contribution of the ground reflection at the shooter’s ears and is not representative of how firearms are typically fired. The aim of this study is to commence empirical development of a standard to assess the noise reduction of firearm suppressors for hearing conservation purposes. Fourteen firearms with and without a suppressor were evaluated with high velocity and low velocity (subsonic) ammunition. Twelve microphones were positioned in a ring 3 meters from the muzzle with 30° spacing and 1.5 meters above the ground. One microphone was positioned at 1 meter to the left of the muzzle and two microphones were positioned at 15 centimeters from the right and left ears of the firearm operator. The suppressors were effective in reducing the peak sound pressure levels between 3 and 28 dB and A-weighted equivalent energy (LAEQ) between 2 and 24 dB.

A space-time diversity scheme for interference alignment in uplink cellular systems

引用

Journal of Information and Computational Science 2015年第16期12卷 6177-6185页

作者： Zhang, Jinbo Yuan, Chaowei Wang, Qiucai Science and Technology on Information Transmission and Dissemination in Communication Networks Laboratory The 54th Research Institute of CETC Shijiazhuang China School of Information and Communication Engineering Beijing University of Posts and Telecommunications Beijing China School of Electronic and Control Engineering Chang'an University Xi'an China

Interference Alignment (IA) can effectively increase Degrees-of-freedom (DOF) for cellular systems. In order to improve the Bit Error Rate (BER) performance, we propose a space-time diversity scheme for IA in uplink cellular systems. In the proposed scheme, the reference interference vectors at different time slots are randomly selected, thus the channel between each user and Base Station (BS) is transformed to a time varying Single Input Single Output (SISO) equivalent channel and the space diversity is transformed to the time diversity in SISO equivalent channel. Moreover, each user transmits different combinations of user's data at each time slot, and the time diversity gains in time varying SISO equivalent channels are achieved. Theoretical analysis and simulation results show that the proposed scheme can significantly improve BER performance without reducing DOF. © 2015 by Binary Information Press
