The identification of the modernization is the modernization of the education to important teaching means. Now modern virtual visualization technology in higher education is more and more widely used. Sports as one of the disciplines with a financial knowledge, and skills training, and physical exercise, and molding temperament is a play. This paper mainly put forward the ways of how to use modern...
Museum is one of places for recreation and education that can be visited by all ages, from children to adults. Elements of pedagogy in the museum can not be abandoned, and the current geological museum has begun to implement some of the technology, so users can capture the contents of the knowledge contained in it with easy and interesting. The study was conducted to determine the incorporation of...
When properly employed, oil mist lubrication offers many benefits to the operation of electric motors with rolling element bearings. Cooler operating temperatures, increased reliability, and decreased maintenance issues are some of the achievable advantages associated with this system. However, there are also a host of concerns associated with its use. The costs of installing and operating a mist...
The goal of this paper is to present a case study that considers the non-destructive testing problem of a cured in place pipe sample. We employ synthetic aperture radar (SAR) to remotely detect artificial boreholes in the dielectric object. Broadband frequency modulated signals are generated and recorded by a vector network analyzer in the frequency range between 75 and 100GHz. Subsequent processing...
In this paper the realization of computer adaptive testing using mathematical-statistical tools of Item Response Theory is considered. It is aimed for knowledge level quick determination of full-time students and distance educations students, and to identify gaps in their knowledge. The goal of computer adaptive testing is a student knowledge assessment. But mainly it is making recommendations for...
There were carried out a research and results' analysis of switching properties of contacts made of Ag-W and Ag-W-Re consisting of 50% of Ag and 1-4% of Re. Contacts were made using powder metallurgy methods: Press-Sinter-Repress and Press-Sinter-Infiltrate method. Arc erosion tests, measurements of contact resistance change and contacts' tack welding tests were carried out in model testing conditions...
The article is devoted to presenting the distant form of training translation skills that has become an integral part of a modern engineer's competence. A special program implemented on the basis of the e-learning site and aimed at training the skills of professional translation of engineers is examined. The peculiarities, advantages, results and stages of the program are analyzed.
With technologies shrinking and design complexity increasing, it becomes crucial that embedded in chip test and repair solutions keep up with the advances in order to consistently provide superior chip quality and yield optimization. The embedded test approaches developed for designs done a few years ago are not sufficient for today's designs, which are bigger, faster, hierarchical and much more sensitive...
Classification is a rather omnipresent problem in many of the technological areas ranging from image processing to medical applications. With complex-valued neural network classifiers posing better decision making capabilities due to its orthogonal decision boundaries and it's comparatively better computational capability many complex valued neural network (CVNN) classifiers has been presented in...
Online learning has already been accepted as an alternative or improvement of the conventional learning model. This research was aimed to know whether there was an influence of learning model towards the student academic achievement in the Management Department, School of Business Management and Information System Department, School of Information System at BINUS University. Research used the experimental...
A spoof or fake is a counterfeit biometric that is used in an attempt to circumvent a biometric sensor Liveness detection distinguishes between live and fake biometric traits. Liveness detection is based on the principle that additional information can be garnered above and beyond the data procured by a standard verification system, and this additional data can be used to verify if a biometric measure...
As the adoption of Cu bond wires continues, increasing quantity of component families are being qualified by component suppliers using standard acceleration test methods and durations. While these tests provide a benchmark comparison with conventional technologies such as Au wire bonding, for users of these components for high-reliability applications, a frequent discussion on reliability assessment...
The study of flip chip solder bump electromigration reliability is mainly on daisy chain test structures on small test die that was subjected to high temperature and current density. Then an electromigration design rule is established based on the results on the test structures. However, for the big die flip chip BGA package, the actual electrical and thermal mechanical stress conditions of solder...
The test of each wafer product in Sort (final IC testing) is done by allocating a tester and an appropriate Sort Interface Unit (SIU) to the product, to perform the test programs over the wafer. This allocation problem is a more complex allocation problem in the presence of a queue time restriction. In this paper, this problem is formulated and solved to determine the optimal allocation of testers...
There are some benefits for embedded passive devices, such as higher reliability by eliminating the solder joint failure from the surface discrete components, real-estate reduction by reducing the physical size of the printed circuit board assembly (PCBA) surface area, better frequency performance by avoiding the inherent parasitic effects from current surface mount technology (SMT). Definitely, embedded...
The evaluation of reliability performances of a commercial embedded module was proposed. Testing procedure, hardware and software architecture for on-line fault monitoring was implemented. By means of the application of accelerated climatic testing, the final challenge is to implement a model able to statistically prove the quality and reliability of the module.
This work presents the research towards two promising embedding approaches for electronic components with a possible application to integrate a sensor node for structural health monitoring into the structure itself. The production process for both integration methods has been assessed through experimental and simulation effort. Samples with passive components for both presented approaches have been...
Friction and wear study of sliding surfaces plays a prominent role in the development of materials for various applications. The development of a low-cost multipurpose reciprocating tribometer at constant sliding speed to study the tribological properties of a material under dry, wet and high temperature conditions is presented in this paper. The tribometer has the ability of changing its stroke length...
To date, there have been no consumer reports on the quality or long-term reliability of photovoltaic products, so buying modules can be a dicey and pricey undertaking. Even a module that looks good to the average customer may have tiny defects in lamination or soldering that, over time in the field, will become micro cracks or even overheat - requiring expensive repairs or full replacements. This...
This paper presents a concept of use of the rule-based reasoning systems for evaluation and classification of the suppliers. The problem of suppliers selection is widely discussed in literature. Majority of the authors apply the method of multi-criteria evaluation for selection of suppliers, mainly the Analytic Hierarchy Process (AHP) algorithm and related ones, to find its solution. In this paper...
