One of the crucial issues in Adaptive Educational Hypermedia is to recognize which distance learning systems' environment settings can help improve the learning process. This work presents the efforts to find those factors, which could help students in reading those e-curricula which are assembled mostly from pure text, without multimedia elements. The purpose of this work is to define the factors...
This paper examines the expansion of the Learning Management System (LMS) beyond the Academic Institutions' boundaries. This includes taking advantage of the rapid development of Web 2.0 technologies for advancement of e-leaning in engineering education. The exponential expansion of different internet communication methodologies and its utilisation to facilitate the teaching and learning processes...
The paper explains the effectiveness of flexible learning methodology in engineering courses. This is an attempt to explore the traditional educational methods and to discuss the implications of flexible learning tools in engineering courses. It takes into account the latest application of Web 2.0 and other relevant techniques as well as components of delivery and material and resources needed. The...
The presence of new technologies on distance education generates a cloud of learning environments with high presence of multimedia contents and mobility capabilities. The widespread use of mobile technologies, digital TV and Internet enables ubiquitous learning environments that allow students to learn anywhere anytime. However, the diversity of computational and display capabilities of the current...
The development of science and the technology allowed significant enhancements to the methods in presentation of new materials to students. The processors and available memory in time has become smaller, faster, cheaper and power efficient. This development opened the way for the creation of the mobile devices with the graphical and sound interfaces in order to simplify and enhance the communication...
Early-life failure-rate (ELFR) test is a useful gauge to screen out the harmful or latent-defect memory products. In nano-regime, this test is still suitable to be applied on these kinds of memory products. Through this reliability test, some gap-filling quality with W-plug in via or contact structure is not compact well, causing the degradation in electrical characteristics and deteriorating the...
To solve the problem of recognize the causation factor characteristics of emergency in supply chain in different industries, the paper established causation factor index system of emergency in supply chain based on system analytical method, and at the same time, put forward a causation factor characteristics recognition model for emergency in supply chain based on principal component analysis and...
The distortion of a current-steering digital-to-analog converter (DAC) is often dominated by the signal-dependent output impedance. This has normally been analysed by assuming a purely resistive load. When a digital IF signal is generated, the different harmonic bands are separated and can also be filtered separately. This paper illustrates that linearity can be improved considerably by shorting the...
In this paper the necessity of strengthening transportation of fruit and vegetable is discussed systematically. And combined to the characteristic of fruit and vegetable, and the situation of cold storage transportation, storage and transportation relevant technique requirement of fruit and vegetables is analysed, such as temperature, humidity, gas composition, package and vibration, and according...
The paper has constructed the mathematical model on the storage location assignment in AS/RS, and then optimized and solved it, performed instance simulation design and analysis on the storage location assignment by means of Flexsim. Finally, we have concluded that the storage location assignment model after optimization would solve the storage location assignment problem in AS/RS effectively and...
Ever more students start their master programme with a bachelor degree which does not provide the ideal background for their study. Such students benefit from dedicated help when they have to master advanced topics in automation, control and electrical engineering. Because individual help is adequate but too labour-intensive, a self-study package has been developed by which individual students can...
A critical problem facing the mechanical design community is that of bridging the gap between mechanical CAD data and finite element models.In this paper, We developed a 2D finite element analysis (FEA) data creating system in which the data is generated from DXF (drawing interchange file) data, which is one of the most famous CAD data. The system is proposed and the usefulness of the system is clarified...
As public goods, hospital materials lack internal cost pressure and external efficiency motive, so there are many problems in the supply system of hospital materials - the sluggish prediction of medical material demand as well as the patient-oriented response plan, ineffective information communication and coordination between supply and demand of materials, inadequate standardization of management...
Taking the electronic manufacturer Y as an example, this paper uses the stream-flow diagram to discuss the improvement process of such a production system. Based on the theory of lean value and the production process status of this factory, it describes the process with the visualized way and identifies the main kinds of waste. And working out the optimal output of products by the mathematical model...
As natural disasters are becoming more frequent, especially the recent "Haiti's earthquake" has once again reiterated the important role of the Emergency Logistics, and the inventory management in emergency logistics is one of the important part. This paper aimed at the deficient of traditional methods of inventory management in the emergency logistics, forecast the demand for all kinds...
The tailing belongs to Handan-tailing which is a high calcium, magnesium tailings, the main mineral component is pyroxene, calcite, chlorite, white mica, etc. secondary mineral component is quartz, pyrite, feldspar. The average partical size of the mineral is 0.37 mm, viscous particle content of 18%. The plasticity of the tailings is better, and drying sensitivity of the tailings is lower. All tailings...
The topology optimization of YKS5120B-3 NC gear shaper machine tool bed is completed based on ANSYS with the shape envelope of the whole tool bed as solution domain and the minimum static compliance as objective function. The optimal topology model of the tool bed is obtained. And then the tool bed model is reconstructed in Pro/E and re-tested by static and dynamic analysis in ANSAYS. The re-tested...
This paper reviews College students frequently have more complex problems today, including both the typical or expected college student problems difficulties in relationships and developmental issues as well as the more severe problems, such as depression, sexual assault and thoughts of suicide. That is the finding of a study involving 600 students seeking help in Henan Polytechnic University over...
In the biodegradation of Formaldehyde gas with a biotrickling filter, a portion of Formaldehyde is solved in the recirculating trickling liquid. As a consequence, the treatment efficiency is limited. The study explored the feasibility of removing the liquid-phase formaldehyde by inducing chemical reactions in the trickling liquid. Experiments were conducted to test three chemicals (sodium sulfite...
