IOP Conference Series: Materials science and Engineering 2015年第1期95卷

作者： M Baier J Franiasz P Mierzwa D Wylenzek Silesian University of Technology Faculty of Mechanical Engineering 18A Konarskiego Street 44-100 Gliwice Poland Silesian University of Technology Faculty of Automatic Control Electronics and Computer Science 16 Akademicka Street 44-100 Gliwice Poland

An engine test stand created especially for research of electrical race car is described in the paper. The car is an aim of Silesian Greenpower project whose participants build and test electrical vehicles to take part in international races in Great Britain. The engine test stand is used to test and measure the characteristics of vehicles and their engines. It has been designed particularly to test the electric cars engineered by students of Silesian Greenpower project. The article contains a description how the test stand works and shows its versatility in many areas. The paper presents both construction of the test stand, control system and sample results of conducted research. The engine test stand was designed and modified using PLM Siemens NX 8.5. The construction of the test stand is highly modular, which means it can be used both for testing the vehicle itself or for tests without the vehicle. The test stand has its own wheel, motor, powertrain and braking system with second engine. Such solution enables verifying various concepts without changing the construction of the vehicle. The control system and measurement system are realized by enabling National Instruments product myRIO (RIO - Reconfigurable Input/Output). This controller in combination with powerful LabVIEW environment performs as an advanced tool to control torque and speed simultaneously. It is crucial as far as the test stand is equipped in two motors - the one being tested and the braking one. The feedback loop is realized by an optical encoder cooperating with the rotor mounted on the wheel. The results of tests are shown live on the screen both as a chart and as single values. After performing several tests there is a report generated. The engine test stand is widely used during process of the Silesian Greenpower vehicle design. Its versatility enables powertrain testing, wheels and tires tests, thermal analysis and more.

IEEE International Conference on Acoustics, Speech and Signal Processing

The problem of elimination of impulsive disturbances from archive audio signals is considered and its new solution, called predictive matched filtering, is proposed. The new approach is based on the observation that a large percentage of noise pulses corrupting archive audio recordings have highly repetitive shapes that match several typical "patterns", called click templates. To localize noise pulses, click templates can be correlated with the sequence of multi-step-ahead prediction errors yielded by the model-based signal predictor. It is shown that predictive matched filtering is an efficient and computationally affordable disturbance localization technique - when combined with the classical detection method based on autoregressive modeling, it can significantly improve restoration results.

Nowadays parallel manipulators are used widely in bioengineering applications;this leads to many exciting expectations as well as challenges. The kinematic analysis of parallel manipulators with their differential kinematics yielding the Jacobian in a closed form is not a trivial task. In this paper a parallel manipulator based mobility assistive device called EJADII is analyzed to determine forward kinematics, inverse kinematics and closed-form Jacobian. An Adaptive Neuro-Fuzzy Inference System (ANFIS) is trained to estimate the Jacobian. This system would be useful when determination of the Jacobian in a closed-form is difficult to determine. The human motion during sit to stand captured by VICON experiment is used with two assisting scenarios to train and verify this system. computer simulations show relatively good results of the proposed system. © 2014 IEEE.

We examine online sociality in Quora, a collaborative Q&A platform, through statistical analysis of 248 answers. Quora members interact through technology and with technology, creating different regimes of sociality: a regime of visibility, in which users and technology assemble the ranked list of answers; a regime of recognition, in which members rely on answers and authors' identity to acknowledge value; a regime of interaction, in which members comment on posted answers. We classify answers in three clusters: Sympa, Inspire and Casual. Answer types are related to the socio-technical creation of sociality regimes.

作者： Constantin, Iulia-Cristina Constantin, Costel Iliescu, Sergiu Stelian Faculty of Automatic Control and Computer Science University Politehnica of Bucharest Romania Faculty of Power Engineering University Politehnica of Bucharest Romania

For several decades, the power system protection relay has experienced many important changes, from purely electromechanical type to the mixture of electronic and electromechanical type, then to fully static and now fully numerical relays based on microprocessors. In the transformer protection area, similar changes can be seen. This new numerical technology had been developed so much that now the protection systems integrates in the same device, besides the protection function also the control functions, this kind of systems also being called as multifunctional protection system (MPS). The paper relieve the main features of the newly developed transformer protection and control systems, the positive impact on the faults clearance times and also the development trends in this domain .

The paper presents an integrated system for Urban Traffic Monitoring and control conceived in the perspective of a Cyber Physical Approach. Traffic actors are defined as classes of agents, each of them with a set of possible behaviors and behavioral drivers. Some of the behaviors are dependent on the actual physical structure/implementation of agents. Different levels of control can be defined with regard to the physical functioning context and the overall system will have a complex emergent behavior. At this moment of conception, traffic actors include mainly components of traffic infrastructure and respective control and monitoring units, but the design is open-system, so as to define also vehicle class.

DYNAMICAL SYSTEMS-AN INTERNATIONAL JOURNAL 2013年第2期28卷 299-299页

作者： Czornik, Adam Niezabitowski, Michal [a] Faculty of Automatic Control Electronics and Computer Science Silesian University of Technology Akademicka 16 St. 44-101 Gliwice Poland

In this article we propose a generalization of the concept of Lyapunov exponents for discrete linear systems which may be used in the case of unbounded coefficients. We show some simplest properties of this generalization and apply it to define a generalization of regular system. Finally, we discuss the problem of stability by linear approximation.
