This article combining Internet development under innovation 2.0 with the new form of material management, take West Inner Mongolia Central Railway Corporation for example. Through discussion, it propose a new mode of railway materials management and solve the problem which are widespread of the current construction enterprise material management. It will solve deep-seated problems existing in the...
Pool of knowledge available to the mankind depends on the source of learning resources, which can vary from ancient printed documents to present electronic material. The rapid conversion of material available in traditional libraries to digital form needs a significant amount of work if we are to maintain the format and the look of the electronic documents as same as their printed counterparts. Most...
With the development of digital technology, libraries are changing their roles from book providers to e-information providers. Manuscripts are primary source of historic information. Manuscripts are diminishing along with the time. Despite their best efforts, it is difficult to save manuscripts in physical form beyond a time frame. Digital preservation of manuscripts restores it from damage, larceny...
The thoracic impedance (TI) signal, which reflects fluctuations due to CCs and ventilations, has been suggested as a surrogate to compute CC-rate and ventilation-rate during cardiopulmonary resuscitation. This study developed a method based on empirical mode decomposition (EMD) to compute CC-rate and ventilation-rate using exclusively the TI. Twenty out-of-hospital cardiac arrest episodes containing...
In recent years, the number of students who enrolled in the course of Introduction to Information Technology at Mae Fah Luang University, Chiang Rai, Thailand is getting larger and larger. This causes the excessive teaching loads for all limited number of instructors who take responsibility of this course. It also causes some problem on study resources, such as the limited number of laboratories/classrooms...
Nowadays, Web-based learning become one of the most important components in educational technologies and has been widely employed in both educational and non-educational institutions. However, many of the Web-based learning systems are closed system and use private internal format. The learning materials may be dispersed and stored in database or on the server's file system, therefore the learning...
In this paper we present novel techniques to redesign materials of interior virtual scenes. Users would need to provide no more than one example image which has desirable color distribution. Our system modifies the materials of the scene so that the rendering result would similar to the color style of the example image. We first extend ISODATA clustering algorithm to retrieve representative viewpoints...
This paper presents the details of experimental set-up to determine the ballistic limit for the aluminium tank for two cases, empty and water-filled tank. The experiment was carried out at Science and Technology Research Institute for Defense (STRIDE) Batu Arang. The aluminum tank was 3 mm thick, 150 mm wide and 750 mm long. At the end of the tank were closed with two Polymethyl methacrylate (PMMA)...
In order to answer questions arising from the deeper application of flipped classroom, our study proposed an instructional design framework of "flipped classroom on the basis of understanding". In pursuit of facilitating students' understanding, teachers could combine the theory of teaching for understanding with the flipped classroom pattern, reform their teaching beyond flipping classroom...
This paper is devoted to explain certain important aspects of a water rescue helmet. The paper has the following content: Firstly, the head injury theory is explained and the related design criteria are identified. Then the Foam layer design and material selection are conducted. In addition, the helmet sample is evaluated by experiment under safety standard EN1385, results are presented.
Quizzes are among the most widely used resources in web-based education due to their many benefits. However, educators need suitable authoring tools that can be used to create reusable quizzes and to enhance existing materials with them. On the other hand, if teachers use Audience Response Systems (ARSs) they can get instant feedback from their students and thereby enhance their instruction. This...
The information and communication technologies have become increasingly present in education, either as support for classroom learning, whether in distance learning. Among these technologies, software known as Learning Management Systems — LMS are used for better student-teacher communication and especially for providing instructional materials, activities, assessments and other resources to provide...
The overall performance of listed Electric vehicle conductive charge couplers varies greatly based on engineering observations. In the field, excessive temperature rise at the connection between the charging station cord and the vehicle inlet has been noted. The temperature rise can be severe enough to damage the plastic coupler housings on both sides of the connection, and can occur in products that...
The present paper describes the strategies used to compile and teach an Informatics course developed during last years at Tallinn University of Technology. The strategy is based on the main principles of blended learning and the analysis of the results of experiments with students from different faculties. Various tests were carried out to identify students' levels of knowledge and preferences in...
This paper presents new cooling methods for permanent magnet synchronous machines (PMSM) with flux barriers. For a vehicle powertrain application the permanent magnet synchronous machines is a very popular choice, because of high power density, a high efficiency and the small package. However, this machine is susceptible to suffer insulations failures of coils and demagnetization of magnets under...
Effects on electromagnetic field (EMF) characteristics inside aircraft due to internal structures, such as phenol internal walls are experimentally investigated using a reverberation chamber. This is aiming to improve the accuracy of the numerical analysis method for the electromagnetic compatibility estimation of the Boeing 777 class large aircraft based on finite-difference time-domain (FDTD) technique...
When designing the electrical installations of an industry that processes flammable products, it is necessary to know where the classified locations are. These locations are identified in drawings in order to orientate the specification of adequate electrical and electronic equipment. This paper will show why the figures' copy-and-paste practice does not guarantee a cost effective installation and...
In the modern society, education is increasingly changing standards according to people needs, forcing young people to know more. We have many methodologies of teaching, but the most effective is using instruments, that well known to audience. Therefore, it will be productive to use technologies in learning and education processes to increase interest of students towards the different subjects. This...
Spare parts coding system is the basis of spare parts management. The article studies the principles, methods of spare parts coding system and impact for spare parts management information. According to the present situation of spare parts management in Group Company, spare parts center designs a set of spare parts coding system that included spare parts material encode, spare parts sole encode, encode...
engineering changes are not just critical evidences for engineering settlement between the two contracting parties in engineering construction, but also involve in the reallocation of responsibilities and risks such as laws, regulations, structural safety, technical standards, engineering scope, government acceptance, government supervision on quality and safety, health and epidemic prevention, planning,...
