An image-driven, model-free approach to design control systems for a large class of industrial process is proposed. A mathematical model of the process is replaced by sequences of subsequent images which play the role of the process (plant) states. The length of this sequences depends on the speed of the process dynamics and on the frame rate. Firstly, a learning sequence of the system states is collected...
Semiconductor manufacture companies make an effort to reduce the test time for the test cost reduction until mass production starts. One of the effective test time reduction techniques is to improve the parallel test efficiency with the test program optimization by debugging on the automatic test equipment (ATE). However, given the time constraints of production schedules, the available time for the...
The stellarator Wendelstein 7-X (W7-X) has been designed to show that optimized stellarators can achieve and sustain fusion relevant plasma conditions. One of the main optimization criteria was the reduction of the neoclassical transport, which is considered as one of the most critical issues of the stellarator concept. While the demonstration of the neoclassical optimization will definitely be one...
A novel approach of a test environment for embedded networking nodes has been conceptualized and implemented. Its basis is the use of virtual nodes in a PC environment, where each node executes the original embedded code. Different nodes run in parallel, connected via so-called virtual channels. The environment allows to modifying the behavior of the virtual channels as well as the overall topology...
Artificial Immune Recognition System (AIRS) is an algorithm inspired by animal immune system in the biological world. It is specialized in solving pattern recognition problems. Heating, Ventilation and Air Conditioning (HVAC) systems are widely installed in modern buildings to provide the occupants with a satisfactory indoor environment. HVAC systems are the some of the most power consuming equipment...
The objective of this work is to introduce an autonomous Hovercraft with minimum Energy consumption. To achieve this goal, a computer simulation in addition to practical testing of a simple hovercraft model have been carried out. A mathematical model for the hovercraft is considered and simulated in the MATLAB/SIMULINK environment. A navigation system with Global Positioning System (GPS) integrated...
The testing of IC at package level may require complex flows. In such cases, when the shop floor is fed with lots of multiple product lines, the manufacturing execution can suffer of very low efficiency, throughput limitation and longer cycle time than expected. The present work proposes a Mixed Integer Linear Programming model to evaluate the operational efficiency of the shop floor under different...
Detection capability of pulsed eddy current testing device is described and illustrated with an example of an artificial subsurface defect in an electrically conductive steel plate. The investigated eddy current probe is of a differential type, consisting of one excitation and two sensing coils with a ferrite magnetic circuit. The numerical solution is carried out in the COMSOL Multiphysics using...
In this study, we characterized the elastic properties of additive manufactured metal alloy before and after the electrochemical corrosion using the line-focused ultrasonic transducer system. The calculation was based on the measurement of the surface Rayleigh wave's velocity. The result showed that the velocity of the surface wave and the Young's modulus had negative correlation with the degree of...
In many research areas where the hypothetical based study is performed p-value is most commonly used statistical measure for null hypothesis testing. This p-value is deciding factor in considering the hypothesis validity for given population. Such a critical value can sometimes mislead the entire research. So there is always scope in understanding such factors in all possible directions. One of such...
This paper presents hybrid L- and P-stable implicit numerical methods for solving differential equations of electronic circuits and systems. Hybrid methods are developed on the basis of two known subclasses of implicit Runge-Kutta methods commonly referred to as Rado IIA and Lobatto IIIA methods. Comparative analysis of the known methods and the proposed hybrid methods demonstrates a high accuracy...
In recent days lots of effort is spent on the integration of multi-core processors also in embedded realtime systems domain for several reasons, such as continuously increasing performance requirements and stricter power limitations. This trend is reflected also in the automotive field. Another major aspect for this up-coming trend is the increasing amount of ECUs within the vehicle. Modern vehicles...
Visualization of data in learning management systems became essential for easier analysis of learner's behavior and interpretation of results on such system. In this paper, we presented design and development process of dashboard for the prototype of program support-CM Tutor. After analysis of various approaches of designing a learning analytics dashboard, we selected most important items for display...
This paper discusses how to enhance the ability of text modeling in Arabic during chat sessions. Hanini and Jabari et al. modeled the text in chat sessions, but there is still a problem when using Arabic, because the Arabic language is very difficult to comprehend, has complex derivative and many ambiguities. This paper enhanced the previous study and added MADAMIRA tool to analyze the Arabic text...
Recurrent neural networks with various types of hidden units have been used to solve a diverse range of problems involving sequence data. Two of the most recent proposals, gated recurrent units (GRU) and minimal gated units (MGU), have shown comparable promising results on example public datasets. In this paper, we introduce three model variants of the minimal gated unit which further simplify that...
This paper presents an inrush current reduction method for a 1/2 HP (0.4 kW), 220 V, 4.8 A, 4 poles single phase split-phase type induction generator when connected to a grid using single-phase voltage control with power electronic equipment. A study and analysis of relationship between voltage, current and real power by laboratory tests under direct on line and soft connection conditions are given...
Outlier detection is a primary step in many data mining applications. An outlier is an abnormal individual from a population, which usually leads poor accuracy in models. Medical literatures are the most reliable resources for researchers to know the progress in their research areas and latest contributions from others. Traditional keyword search retrieves all the text data that contain the keywords...
There are so many applications using Crowdsource techniques in retrieving data, especially data on the traffic density of vehicles on certain roads, sample applications that already implementing the concept Crowdsourced data such as Waze, Google Maps, Bing Maps, etc. However, from that Crowdsouced data it will arise the question, whether the given data valid? Or how accurate the data provided by the...
We present a model and a hypothesis testing based framework for determining genuinely good service providers from the ratings given to them by customers, allowing ratings to be imperfect representations of the service provided. The problem is complicated because the nature of the customer that rates the service provider affects the reliability of the rating, but this nature is not known a priori and...
Color features extraction is one among methods widely used for mouth extraction. This relates to specific features possessed by mouth color compared to others facial components. Mouth has a strong chromatic color for red but weak for blue. Color features extraction produces colors that are used to generate a mouth map. This map is required for mouth extraction. Some previous researches on mouth extraction...
