The modulation technologies of L1 signal in GPS/Galileo system have reached many achievements. chaotic-BOC showed the new usage Galileo satellite communication. Lü (LS) chaos sequence has perfect chaotic characteristic three -dimension discrete dynamic systems; especially three-dimension data can be orthogonal components. From acquisition and positioning signal, technology was a right way to choose. need parameters at least here just use which could used received signals demodulated get...

It is necessary to analyze the strength of STS crane with static load for assessing safety crane. A case study a 28 ton capacity and 18 years working time has been conducted. testing system signal sensing, conditioning, acquiring analyzing established. After field test, all stresses test positions have calculated in allowable range. As result this study, systematic approach proposed.

The development of intelligent vehicles (IV) promotes smart transportation, and cyber physical systems (CPS) offers the possibility to address increasingly prominent transportation management needs data problems. IVCPS is a technological integration IV, CPS, traffic science, engineering, representing an emerging interdisciplinary complex system. In order accurately comprehensively assess intrinsic functional elements IVCPS, this article constructs framework evaluation, proposes comprehensive...

Due to climate change and the risk of depletion traditional fossil energy, developing renewable energy has become a common consensus international community. Marine current is regarded as most desirable form ocean due its high density strong predictability. However, variations marine velocity caused by swell effect lead fluctuation power. In this paper, an management strategy based on Two-Stage Fuzzy Logical Controller (TSFLC) proposed redistribute power abate fluctuation. The hybrid storage...

Based on the idea of neural network, intelligent computing methods are used to analyze temporal and spatial data. We present autocorrelation moving average (STARMA) model based in-depth systematic study time sequence hybrid model. Firstly this paper uses radial basis function network extract which is non-stationary caused by large-scale non-linear trend, secondly presents STARMA modeling small-scale random variation. Comparative analysis between original data forecasting shows that proposed...

In order to solve the problem in k-means algorithm that inappropriate selection of initial clustering centers often causes local optimum and time complexity is too high when handling large amounts data, a fusion based on geometry proposed this paper. The result experiments shows better than traditional k-means++ algorithms, with higher quality faster speed. And at last paper, we apply it marine engineering.

Traditional digital forensic methods become exceedingly feeble in cloud due to the fact that basic infrastructure turns virtualized environment. Leveraging properties of virtualization, virtual machine introspection has showed potential for forensic. In this paper, we propose a novel framework, which contains trustworthy independent agency, provide memory analysis (DFA) machines (VMs) cloud. With assistance platform, dump files can be obtained and transferred agency further DFA, where...

In this paper, a mode control strategy for two-mode EVT hybrid electric vehicle (HEV) is proposed,considering transmission efficiency and change quality. First,speed torque characteristics are analyzed by establishing relevant equations of two mode. Next,the optimal operation selected from the viewpoint efficiency,when it higher at given speed ratio.Then,two scheme sequence clutch/brake compared,and algorithm synchronous MGs engine suggested to reduce difference between both end clutch...

The current situation of nuclear power plants at home and abroad is described, the impact large-scale accessing to grid analyzed, specifically in aspects modeling, simulation, load following, reliability, fault diagnosis, etc. Nuclear will bring a series problems, causes each problem, main solutions future development directions are summarized.

Objective To explore the effect of exhaust methods at different angles in process outpatient intravenous infusion order to improve efficiency infusion.Methods 370 outpatients were randomly divided into observation group and control group,185 cases each group.Control exhausted by traditional way introduced textbook with a transfusion tube 45 o angle,while 90° angle.By comparing time case consumed entire success rate one exhaust,the clinical two was evaluated.Results Patients who less than 10...

For the depletion of limited traditional energy and deterioration living environment, it is a focus attention word for utilization clean renewable sources such as wind, solar hydrogen Energy. In this paper, design robust voltage source grid-connected converter developed. And used in hybrid power system (HRPS). The electronic control are introduced. Finally, some experimental results presented.

This paper presents a review of some the applications for artificial muscle and several material muscle. We focus attention on polymer muscle, which responds to electrical stimulation with significant change in shape or size. Through our research variety materials analysis mechanical properties movement, finally we designed device imitation muscles stretching device. article describes structure performance
