As the environment pollution is becoming more and more serious and the nature resources have been running out, the electric vehicle plays a more important role in the world. However, it is well known that the inadequate driving range is the inherent limitation that hinders electric vehicles widely. This paper aims to analysis and optimize the low speed electric vehicle material by using hybrid materials...
After teaching and observing students for several years, we hypothesize that learning programming is difficult for students who cannot imagine concretely how a computer works, or the process by which the CPU accesses memory and I/O via the bus according to coded programs. In this paper, we discuss why we believe it is important for programing education to help students understand how a computer works...
In this paper, based on double auction and cell membrane optimization, a novel cloud resource management scheme is proposed with the economic methods adopted and the characteristics of resources and market in cloud environment considered. In the proposed scheme, the resources are priced by double auction, and the best solution for cloud resource allocation is got by cell membrane optimization algorithm...
We have developed a novel microchip aiming to rapidly optimize of electric parameters for electroporation. The electrodes were designed as symmetrical hyperbolic formatted to generate linearly decrescent electric field. Cells were cultured on the microchip for adherent electroporation and in-situ observation. Exhibited diversely in cell viability and transfection efficiency, three areas were observed...
In order to solve the problem of railway emergency materials dispatching optimization considering the difference of the emergency time limit of the materials, the uniqueness of this problem is analyzed and a multi-objective dispatching model is established with multi-objective programming method. On base of satisfying the requirement of emergency time limit of different materials, the model achieves...
To enhance learning, it is desirable to also let students learn from each other, e.g., by working in groups. It is known that such groupwork can improve learning, but the effect strongly depends on how we divide students into groups. In this paper, based on a first approximation model of student interaction, we describe how to optimally divide students into groups so as to optimize the resulting learning...
Students do not always spend enough time studying. How can we encourage them to study more? In this paper, we show that a lot depends on the grading policy. At first glance, the problem of grading may seem straightforward: since our objective is that the students gain the largest amount of knowledge and skills at the end of the class, the grade should describe this amount. We show, however, that it...
The paper extracts acoustic emission signals between the normal condition and the crack state through the micro crack experiment of drawing parts. The local wave decomposition of acoustic emission signals was achieved to get the nine intrinsic mode functions and a tendency by the MATLAB software. The energy value of the former 8th-order IMF (Intrinsic Mode Function) were extracted as the initial characteristic...
The paper focuses on experiences gained during the last years with the WebCT virtual learning environment together with multimedia applications supported education of three subjects. WebCT has been used at the Faculty of Informatics and Management since the beginning of this century. The author of the paper has been prepared with her students various multimedia applications dealing with objects appropriate...
Effects of retention groove location and dimensions of threaded glass fiber post on the maximum retention force of the restorative system and the maximum equivalent stress in the root were numerically investigated. Results show that the retention groove can effectively enhance retention ability and reduce the stress in the root. And the maximum retention force of the restorative system can be increased...
This experiment was an attempt on extract polysaccharide from Argopectens irradias using water and ethanol and assay its contents using sulfuric acid and phenol method. The extraction rate of crude polysaccharide from Argopectens irradias was found to be 5.419 % and its content was 16.13%. The average recovery rate of crude polysaccharide was 100.7% with 1.72% RSD. The results showed that the method...
According to requirements for grading and characteristics, mathematical model of linear vibrating screen with the pursuit of minimum power consumption per productive is established. By means of MATLAB optimization technology, the best design is acquired. The results show that power consumption per productive obtained from optimization is decreased significantly compared with empirical design.
Virtual reality technology has become a main research field of computer development application gradually in recent years. Virtual campus is a specific application of virtual reality technology in the digital campus. The basic principles and key technologies of building virtual campus model are studied in this paper. According to the requirements of virtual reality, virtual campus 3D models are established,...
This paper presents a study of spring-back in the free bending metal forming process, and the analytical model of free bending process is constructed. Different punch radius, die-lip width and sheet thickness are varied to study their effect on spring-back. Abaqus/Explicit is used to simulate the forming process, and Abaqus/Standard is used to simulate the spring-back process. The analysis shows that...
Bamboo has good ecological and cultural values. This paper aims at the re-designing of bamboo products, and talks about their developmental, creative, technological competitive features, which make company fully develop the value of bamboo at a possible low cost. At last, the paper draws to a conclusion that the research would be a trigger for the development of bamboo industry.
This article is discussing in how to optimize a suitable computer aided industrial design software, from the follow three aspect, industrial design students, design company and manufacturers, product type. And conclusing that the key to learning software, “not much, but in essence.“ A good designer should be master one software of every type of software. In accordance with their own strengths, interests,...
For a long time, theoretical teaching has been more important than cultivation of engineering consciousness and engineering practice training in China's computer education, as a result of it, the education system lagged behind the real social demand. The paper brought forward some optimization measures on all kinds of factors and process of teaching activities based on wide and deep investigation...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
The challenges of deriving early-adopter competitive advantage, even with fabless access to process technology, through leveraging features offered by the advanced, and possibly disruptive, process technologies in real SoC products, are outlined. A structured methodology for addressing these challenges, and bridging the gap between process and design, sufficiently early in the development cycle to...
