A conformal rectangular microstrip patch antenna was utilized to determine the dielectric constant of building materials at 2.4 GHz. The antenna was designed using flexible paper substrate and conductive textile. The material under test (MUT) was used as a superstrate to the patch antenna. To estimate the value of εr of the superstrate, closed form expressions for multidielectric layer patch antennas...
In this paper, an electronic components inventory model with fuzzy multi-parameters is considered. Economic order quantity (EOQ) is developed for optimal order quantity with all parameters assumed to be exact or crisp. Actually these parameters are not precise while varying over a range. In such case fuzzy set theory is applied to electronic components inventory planning and control problems. With...
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...
This work describes the ICT learning experience during intensive TAARLoG (Traditional in the Alpe Adria Region - Local for the global) Erasmus project. Project was implemented intensively in Pula in October 2012 with the participation of 54 students from the universities of Pula, Trieste and Maribor. In the multilingual environment (Slovenian, Italian, Croatian and English languages) students were...
Ecology and resource efficiency have achieved high relevance in industry, not only due to their economic effects. Thus, logistics planning is required to contribute to “green” initiatives. However, it still lacks appropriate methods and tools. Simulation represents a well-accepted method in logistics planning, for it can handle dynamics, stochastic effects and a high degree of complexity. In the context...
Sales and operations planning and production planning for vehicle production are carried out mainly with cascading planning processes. This paper focuses on planning of the final assembly of truck manufacturers. In this industrial sector, mixed-model assembly lines show very different capacity requirements according to the product because of high product variants and shifting product mixes. The main...
One way to improve the energy efficiency in manufacturing is the use of energy-sensitive methods in production planning. So far, the energy consumption behavior of production facilities has not been investigated in great detail. Estimates are typically obtained by connected wattage values and concurrency factors. We present a new methodology to simulate and optimize complex robot driven production...
Modern material handling systems (MHS) are complex systems which are controlled by various control units on different automation levels. The design of the MHS facility layout and the development of the control units require the application of different CAE tools but simulation and virtual commissioning does currently not play a significant role because there is no integrated simulation-based verification...
English speech of L1 English and L1 Bengali speakers of the same discourse is analyzed by applying hierarchical discourse prosody framework HPG (Hierarchy of Prosodic Phrase Group) in order to find the between-and within-group similarities and differences in speech planning of L1 (native) and L2 (non-native) English speakers for prosodic organization at discourse level. The analysis reveals that the...
At the end processes of TFT-LCD supply chain, the LCM module factory takes charge of the process of assembling products, and its production planning needs to consider various products with different graded TFT-LCD panels while meeting customers' specific qualifications, including lowest acceptance rates for quality and zero-bad-defect quantity. Since the machine setup time of the bottleneck workstation...
In 2007, the Departments of Homeland Security and Defense created the Interagency Biological Restoration Demonstration (IBRD). The goal of IBRD was to reduce the time and resources necessary to recover a wide urban area following an intentional release of Bacillus anthracis. Early in the program it became clear that the absence of a systematic approach to planning for and executing recovery (specifically...
This work in progress explores the landscape of computing learning resources and environments found on the web together with teaching and learning materials that can facilitate the integration of “computational thinking” into the K-12 classroom. In specific, this paper focuses in finding and describing existing learning environments that integrate computational thinking into a STEM discipline together...
We propose an introductory level teaching and learning curriculum for the ASEE COMPLEETE program (COMPetencies in Learning for Engineering and Engineering Technology Educators). COMPLEETE is an initiative for a national program to build and recognize educator excellence in engineering and engineering technology at three levels. The proposed curriculum for the introductory level is compared with curricula...
Learning activities' guides tell students which tasks and when they should be carried out to attain the educational goals of corresponding courses. In this paper, an easy to use framework for developing and using these guides is presented. Results of its use show that students are satisfied with them but that there is room for improvement in augmenting their capabilities.
Many people take it for granted that the college English teaching mode for “leaner autonomy” is nothing but to ask students to learn to self-study with the student-centered class teaching. In fact, the scientific college English teaching mode for “leaner autonomy” is not just the case at all. It is the product of modern high technology and the embodiment of the theory of “leaner autonomy” in college...
Due to the lack of efficiency communication and collaboration among each manufacturing department, it makes long lead-time and high cost for the manufacturing of aircraft structure parts which have the characteristics of multi-varieties, complexity structure, and small batch. In order to address these challenge issues, a feature-based and multi-agents-based manufacturing collaborative framework which...
Construction materials usually constitute a major portion of the total cost in a building construction project, which makes the control of this resource important. Despite the potential benefit of Information and Communication Technology (ICT), convincing construction organisations to embrace its use and implementation has proved a difficult task. This paper aims to present a review of the existing...
Reduction of resource consumption in data centers is becoming a growing concern for data center designers, operators and users. Accordingly, interest in the use of renewable energy to provide some portion of a data center's overall energy usage is also growing. One key concern is that the amount of renewable energy necessary to satisfy a typical data center's power consumption can lead to prohibitively...
Dry bulk terminals, located near the deep sea, are used all around the world to handle large quantities of bulk materials, like coal and iron ore. Bulk materials are transported within the terminal using routes of interconnected belt conveyors. Due to several sources of uncertainty, such as the delays of ships and trains and disturbances of terminal equipment, selecting routes is complicated and is...
Digital game-based learning (DGBL) has successfully brought traditional game-based learning (GBL) into a new horizon due to its multimedia features, high interactivity, immediate and various feedbacks, authentic and vicarious contexts, etc. As a result, PC-based DGBL has been prevalent in the past decade. In terms of socio-cultural theory, however, PC-based DGBL has some drawbacks in nature to effectively...
