With the rapid development of informatization and the popularity of computer application, higher requirements are put forward for computer teaching in university. As one of the basic courses in universitie, “Computer Sience” carried out some reforms in the teaching content, but the teaching method is still based on instruction, supplemented by the computer exercises. The paper puts forward the blended...
The fast advancement of information and communication technologies (ICTs) globally has increased the obtainability, accessibility, and processing of knowledge sharing and management more than ever before in the world. This research takes the theory of social identity and social network as the main core to examine green fashion communities members how to use social media to knowledge sharing. Using...
The need for green products can vary due to differences in cultural beliefs and consumers' active sharing and participation on green environmental issues in the world. The cultural beliefs toward environmental friendly events also differ through involving social and economic matters. Therefore, this study looks for understanding consumers' green repeat purchase intention based on the theory of perceived...
Many technical and vocational universities are established with an aim of matching up with national and industrial development so as to cultivate senior talents economic in professional technology application. Thus, human resources and qualities of graduates from higher technical and vocational education system exert considerable influences on national economic, industrial and commercial development...
In an appearing and exceedingly competitive digital commerce environment, consumers' repurchase intention has seemed as a very crucial component among online vendors and firms by degrees. The service quality is believed to have an influence on consumers' repurchase intention in E-commerce context. The objective of this paper is to examine the differences and similarities of website service quality...
Cooperative guidance is the key technology of multi-missiles cooperative attack, in which the method to control impact time and impact angle is the research hotspot. This paper focuses on this research direction. In this paper, cooperative guidance geometry of multi-missiles and target is given in the beginning. The cooperative guidance problem of attack time and the attack angle constraint under...
In a high movement environment, handover occurs frequently in a mobile network and degrades the quality of mobile communication and service. The shorter the handover delay is, the better the communication quality can be obtained. To shorten the handover delay for a bunch of UEs moving in the same direction, mobile relays (MR), an intermediate role between a UE and an eNodeB (eNB), have been introduced...
A novel observer-based feedforward compensation method is proposed to improve the output voltage regulation of a boost power-factor-correction (PFC) rectifier. A feedback observer estimates the load current for use in the feedforward correction of the inductor current. The feedback gain of the observer is intimately related to the regulation error of the output voltage. Given required performance,...
The progress of medical science and technology to extend the average life expectancy of mankind, aging population changed social structure and health condition, anti-aging has become a new indicator of future industry, in today's society, everyone emphasizes the importance of self-marketing.
Archaeologists have found that thousands of years ago the Egyptians have already begun to use skin care products. After the evolution of the times and the development of science and technology so far, hundreds of thousands of kinds of cosmetic formulations varied. In order to keep the cosmetics in different climates, temperatures and environments, although the chemical formula they add could achieve...
For missiles with passive seeker, they are usually little observable because only the line of sight (LOS) information is obtained without distance information. It's difficult to take both aspects that the observability of filtering model and hit accuracy of the maneuvering target, into account at the same time. For this problem, the motion tracking sliding mode guidance law is adopted in this paper,...
A FEM simulation of AFM indentation of soft biomaterials was made in ANSYS based on five-parameter hyperelastic Mooney Rivlin model. The simulation result shows that: The finite thickness film behavior is stiffer than the thicker film at larger indentations.
This paper reports a combinational near infrared (NIR) and intense pulse light (IPL) sintering method for enhancing the surface morphology of metal mesh printed in organic light emitting diodes (OLEDs). This roll-to-roll process-supportive NIR and IPL sintering improved the as-printed surface roughness by 60.5%, implying improved OLED stability and reliability. In addition to surface roughness, structural...
A diagnostic system was setup to test the ferroelectric micro-plasma thruster(FMPT). The V-I characteristic of the FMPT was measured. The optical spectrum of microplasma generated in FMPT was obtained. Additionally, the electron temperature has been found to be ∼3.43 eV from atomic Boltzmann plots of neutral Ag I lines.
Heterogeneous system architectures are evolving towards tighter integration among devices, with emerging features such as shared virtual memory, memory coherence, and systemwide atomics. Languages, device architectures, system specifications, and applications are rapidly adapting to the challenges and opportunities of tightly integrated heterogeneous platforms. Programming languages such as OpenCL...
A submicron (280-nm), thin (3-nm) and transferrable graphene oxide grating layer is implemented for the first time by interference lithography, oxygen plasma etching, and PMMA-assisted transfer approach. The diffraction efficiency is measured to be only 4.98×10−7.
The three-dimensional deformation of fish caudal fin during swimming was reported in several teleost bony fish species, e.g., bluegill sunfish (Lepomis macrochirus) and cichlid fish (Pseudotropheus greshakei). However, few study has addressed the effect of 3D locomotion on its thrust efficiency quantitatively. In this paper, we first performed biological observations on yellow perch (Perca flavescens)...
In this paper, we present the design, fabrication and the mathematical model of an entire soft robotic arm with three-dimensional (3D) locomotion. We first describe the design of the soft arm based on 3D printed channels that were spatially distributed at the interface of two different silicone elastomeric materials which enable complex 3D motion of the soft arm. Then we demonstrate the workspace...
A on-board ship targets detection method based on multi-scale salience enhancement is proposed. Unlike the traditional wavelet filter enhancement methods, the proposed utilizes the wavelet decomposition to obtain the high-low frequency parts, and estimate the salience feature with both parts, which enhance the ship targets efficiently. First, decompose the remote sensing image by 2-D DWT, and obtain...
Aiming to reduce the thick cloud interference in target detection, this paper proposed a thick cloud region detection method based on double scale ocean background Gauss model for large scale high resolution ocean remote sensing images. Firstly, the paper analyzed the statistical characteristics of seawater background and thick cloud with Haar wavelet decomposition principle, and it found they are...
