The physical weak-discontinuous problem of an interfacial crack between homogeneous materials and functionally graded materials (FGMs) is studied based on Reissner's plates considering transverse shear deformation effect. The higher order crack tip fields of homogeneous materials and FGMs regions are obtained by the eigen-expansion method. The normalized stress intensity factors(SIFs) and stress distributions...
Today, there is no non-destructive, simple, inexpensive and yet accurate in-situ monitoring technique for cracks and delamination available for routine use in electronic package testing. However, such a method is highly desirable, as delamination testing is part of every qualification programme in industry. Rapid failure analytical techniques which allow introspect and easy-to-interpret information...
China is the largest producer and consumer of vegetables in the world. Manual indenting and sowing of small vegetable seeds in plug trays is a slow and labor-intensive operation. Therefore, seeding operation of plug trays should be mechanized to increase the capacity of the rapidly expanding nursery industry. A tray precision seeding machine is one of the key devices used in industrialized plug seedling...
We investigated the mechanical properties of a silver sinter paste dependent on sintering and drying conditions. For these experiments we fabricated dedicated samples without silicon and leadframe to investigate the pure material properties. Our investigation on the influence of drying and sintering conditions demonstrated that the longer the sintering time and the higher the temperature the higher...
Under the background of economic globalization, the demand of the excellent bilinguals is growing rapidly in the whole world. The Chinese-Foreign Cooperation in Running Schools (CFCRS) came into being and is moving forward through twists and turns. It is necessary to find a suitable bilingual teaching model. This paper is mainly based on the status of bilingual teaching in the Chinese-Foreign Cooperation...
In the molten rock deformation experiments images often shaped by exposure of different photos stitched together, for the molten maldistribution problem of the mosaic effect, this paper presents a method based on quadratic threshold determination to balance, It can be seen, compared with the nonlinear dynamic range adjustment method, this method can better solve the problem of mosaic effect.
In today's society, our life has fully stepped into the computer information age, and various kinds of multimedia equipments have been closely linked with our life. With the continuous development of the information society, the computer information technology has an important influence in the education field. How to combine college teaching with information technology and realize the coordinated...
In this paper, the authors present an engineering approach for generating automation system solutions based on formalised requirements. This enables assistant systems which guide engineers during the design phase of todays more and more complex automation systems. A software prototype is used for the evaluation of this approach in practice. The main contribution is to directly use a formal requirements...
Material distribution in discrete manufacturing workshop suffers from a bottleneck of capturing and collecting real-time field information. Without up-to-date information, the staff will be difficult to make accurate decisions. It seems that Real-time locating system (RTLS) is a good solution in the modern manufacturing. Based on the RTLS platform, this paper raises the concept CGV (Coordinate Guided...
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 recent years, an innovative approach to learning has been developed to construct a context-aware mobile learning platform based on situated learning. In this study, we utilized NFC-enabled smartphones with context-aware technology to propose a Context-Aware Mobile JApanese conversation Learning system (CAMJAL) for non-native learners. Our proposed system implemented and recorded learning behaviors...
Aterramento do neutro é uma questão de grande importância nos sistemas elétricos das indústrias de petróleo, química, gás e outras indústrias. Essa importância se deve ao fato de que cerca de 85% dos curto-circuitos que ocorrem em sistemas elétricos industriais são fase-terra, o que pode causar sobretensões transitórias, arco elétrico, incêndio danos em pessoas e encerramento do processo industrial...
In recent years comfort has become an important factor when evaluating the performance of modern automobiles. One important aspect that has negative ramifications on the perception of the quality is the generated noise, which mainly contributes to the disturbing noise level of urban regions. Therefore, an important goal in current research is the attenuation of the noise level of car engines. The...
In the present investigation the corrosion behavior of dissimilar A6063 and A319 caste alloy plates joined by friction stir welding (FSW) was evaluated. The effect of tool rotation and welding speeds as well as post weld heat treatment (PWHT) on the corrosion behavior were investigated. Plates of A6063 and A319 were friction stir welding used in three different rotation speeds (typically 1200, 1000...
A bearing is a machine element used to constrain relative motion and reduces friction between moving parts with necessary lubrication provided. Bi-metal aluminium bearing manufacturers say their products offer long-term durability, dry-start protection, resistance to debris, corrosion resistance and dimensional accuracy for stock and light duty, as well as performance and racing, applications. The...
Hydrophobicity is an important operating performance indicator for composite insulators and the regularity of hydrophobicity distribution contributes to a more accurate evaluation to test results. In this paper, four DC composite insulators energized over a period of years in South China were selected for test and hydrophobicity tests were conducted by using static contact angle method. These tests...
Manufacturing industries are adjusting their operations and strategies to gain sustainable competitive advantage. Many enterprises regard logistics as the core competency of their corporate strategy. Global logistic service companies often report limitations and challenges to supply chain integration including decreased transportation efficiency, diminished information transparency, and reduced material,...
GenVirtual is a augmented reality musical software that allows development of activities in music therapy. This study aimed to analyze the perceptions of other health professionals about the clinical utility of GenVirtual. A secondary objective was to understand the attitudes of these professionals facing the augmented reality technology. Three focus groups composed of music therapists, occupational...
In this paper, we discuss the addition of automatic assignment of mentors during in-class lab work to an existing online platform for programing practice. SingPath is an web based tool for users to practice programming in several software languages. The platform started as a tool to provide students with online feedback on solutions to programming problems and expanded over time to support different...
A fundamental artifact of any academic research is the data used as the basis of that research effort. A group of researchers, from institutions in multiple territories, has embarked on an ambitious research project that is aimed at enhancing the teaching of software engineering in four-year undergraduate programs. The research project details a set of workshops, for which the objective is the capture...
