In this paper, we present results of our research on designing and implementing a prototype of a redundant system for satellite on-board computer using Intel Galileo. The system is designed to simulate fault tolerant system on satellite on-board computer. The triple modular redundant system implemented on a Linux-based operating system that installed on the on-board computer. Simulation is carried...
Handwriting disability is one type of learning disability that is difficult to be detected as it may requires experts and professionals to diagnose. Owing to this matter, a computerized character recognition application is very much in need to ease the process of detecting children with learning disability based on handwriting. For any character recognition method, it's critical to extract the class...
Universities and other educational organizations are adopting computer and Internet-based assessment tools (herein called e-exams) to reach widespread audiences. While this makes examination tests more accessible, it exposes them to new threats. At present, there are very few strategies to check such systems for security, also there is a lack of formal security definitions in this domain. This paper...
Brake valve springs, such as 104 and F8 valve springs, are essential components in a braking system of a passenger train. Their maintenance quality has a direct impact on the vehicle operation security. In this paper, a new kind of testing system was developed for springs used in brake valves. This system overcame several shortcomings of existing ones and could meet the requirements of new standard...
A new method of training deep neural networks including the convolutional network is proposed. The method deconvexifies the normalized risk-averting error (NRAE) gradually and switches to the risk-averting error (RAE) whenever RAE is computationally manageable. The method creates tunnels between the depressed regions around saddle points, tilts the plateaus, and eliminates nonglobal local minima....
Emerging photovoltaic products have expanded the applications for the technologies into markets previously unconsidered for what was thought to be a delicate electronic product. One company leading this effort, Solar Roadways, Incorporated, is producing pavement replacing photovoltaic systems and proposing their use in everything from sidewalks to runways. Current pavement testing methods cannot be...
The paper addresses the problem of reverse engineering a function block (FB) in situations when its source code is either not available or is too complex to understand. The proposed approach builds up on a recent method for reconstructing FBs based on testing and a search-based optimization algorithm. In our work the method is augmented with candidate solution verification using the NuSMV model checker...
This paper presents the design, deployment, and initial testing of an agent-based test bed to support a wide range of experiments and demonstrations of advanced control of building systems for energy efficiency, occupant comfort, and reliable interaction with the electric power grid. The test bed possesses the following major characteristics: 1) it supports interactions among heterogeneous components...
Voltage source inverters are essential systems in many applications. Thus, the diagnosis of the faults that could appear in these systems allows detecting, isolating, and identifying the faults. In this context the teaching of this subject is becoming very important. However, laboratory experience is fundamental in order to provide a real understanding of this subject. This paper presents a computer...
Any adaptive traffic control system applied for an entire network must be flexible, in order to adjust the signalling times for each junction according with real traffic data, according to a macroscopic vision. Also, it must be network synchronized, in order for each signalling time modification to be correlated with the other junctions in the network. The system must also be able to properly respond...
Process of development complex electronic control units (ECUs) is usually complex and requires several iterations (releases). After each iteration, it is necessary to perform detailed testing and verification of all components in a testing environment that is as similar as possible to the real system. For this kind of testing it is recommended to use the automated testing environment that generates...
The rise of the Internet of Things, social networking, and embedded connectivity has led to an explosion of available data. In order to better analyze this big data, many different tools have been created that can process the data efficiently. However, the increase in the amount of tools available makes it more difficult to determine which one will provide the most efficient solution to a given big...
With the rapid development of technology, Internet has changed people's lives and online community has become a comprehensive platform for exchanging ideas and shopping. This study develops and tests an environmental psychology model of online impulse purchase. The model captures the moderating effect of search and experience product type on the relationship between the online impulse buying intention...
This paper analyzes the most useful and popular classification algorithms used by the Machine Learning systems, particularly in the artificial intelligent systems. It is focused on the practical applying of classification algorithms, in all three different dataset used throughout this paper. The results of the paper show which algorithm is more convenient for a particular dataset. The common analysis...
To accelerate research and development of the autonomous capabilities of micro aerial vehicles we have developed flight control framework, ROSflight, as a research tool. ROSflight makes development of autopilot code easier and more efficient by minimizing the use of embedded systems, incorporating the Robot Operating System and using off-the-shelf and open-source hardware and software. Motivation...
Human recognition has been an active research area in the past decade. As the traditional biometrics such as face, fingerprint and iris have been widely deployed around the world, the vulnerability of such systems to falsification and spoofing attacks has been admitted. ECG is related to electrical activities of heart and is among the newer additions to biometric family. In addition to its inherent...
The development of computer based systems expands the usage of computer based application in human life. It can be observed that illegal activities such as unauthorized data access, data theft, data modification and various other intrusion activities are rapidly growing during last decade. Hence, deployment and continuous improvement of Intrusion Detection Systems (IDS) are of paramount importance...
Preventive screening examinations of the population are one of the most effective ways to prevent COPD today. In this paper the problem of technical support of chronic obstructive pulmonary disease diagnosis is described. Transmit channel data and testing of technical capabilities of NRF24L01-module for implementation in screening diagnostic system are analyzed. The present measurements agree with...
This paper analyzes the traditional game system, pointing out its shortcoming and putting forward an idea of designing a Distributed System (which is referred to as DS) Computer Game Platform. At first, the paper puts forward the structure of DS computer game platform and introduces several functions. After that, the paper proves the practicability of DS computer game system in several different aspects...
PUF is a security primitive that exploits the fact that no two ICs are exactly the same. To verify a new PUF design, several metrics including uniqueness, reliability, and randomness must be evaluated, which requires various resources and a long set-up time. In this live demonstration, we have developed an automatically evaluation platform for the PUF design. To the authors' best knowledge, this is...
