In this article, the database of sEMG corresponding to the six gestures with two,four and eight channels is collected and established through increasing the number of surface electrode muscle telecommunication reasonably.Two-channel method used in the previous studies in laboratory is improved to make the method suitable for four-channel and eight-channel.On this basis ,the activity of sEMG is detected,the...
Using health claims data of the Austrian social security system we derived networks of healthcare providers who share patients. Hereby we focused on networks of primary care physicians. Based on the characteristics of these networks potential implications for the upcoming Austrian national EHR system ELGA were drawn. Amongst others we conclude from our analysis that Austrian urban primary care physicians...
Building complex and trustworthy software systems in the shortest time-to-market remains the challenging objective that competitive companies are facing constantly, and mastering the development process is a key issue towards this objective. Companies need to be able to formalize their development processes in order to analyze them, to enact them, and to assess them for quality measurement and efficiency...
Autonomic Computing Systems are oriented to prevent the human intervention and to enable distributed systems to manage themselves. One of their challenges is the efficient monitoring at runtime oriented to collect information from which the system can automatically repair itself in case of failure. Quasi-Synchronous Check pointing is a well-known technique, which allows processes to recover in spite...
The skills needed to build the next-generation of power semiconductor devices and to integrate them into power electronic systems require proper education and training of engineering students, both at the undergraduate and graduate levels. To assess the current state of power electronics education, a study of curricular offering in power electronics in the U.S. universities is conducted. The study...
We propose an approach for addressing the challenges and meeting the needs of industrial networking education. The approach is based on using open source resources, key networking technologies, and an experimental framework to revolutionize the way industrial networking ought to be taught at higher learning institutions around the world. Based on the approach a new type of industrial networking course...
This paper presents a control algorithm for dc-bus stabilization in weak network that uses a Li-ion battery as the battery substation. The battery modules connected with 2-quadrant 4-phase parallel converter with interleaved technique. In this paper, a nonlinear control algorithm based on the flatness properties of the system is proposed. Using the flatness property, we propose simple solutions to...
This paper explores the design of a collimating lens based on freeform method. With this freeform structure, the light can be propagated as nearly parallel light which allow the light be transmitted to a large distance without substantial loss.
Along with the emergence of massive graph-modeled data, it is of great importance to investigate graph similarity join due to its wide applications for multiple purposes, including data cleaning, near duplicate detection, etc. This paper considers graph similarity joins with edit distance constraints, which return pairs of graphs such that their edit distances are no larger than a given threshold...
Cyber-physical systems are integrations of computation, communication networks, and physical dynamics. Although time plays a central role in the physical world, all widely used software abstractions lack temporal semantics. The notion of correct execution of a program written in every widely-used programming language today does not depend on the temporal behavior of the program. But temporal behavior...
The authors present a complex of computer laboratories that simulates major subsystems of electrophysical facilities. Lab software interface creates a research environment with diverse electrophysical equipment, including assembly of the experimental circuits, setting their parameters and characteristics, starting and carrying out the necessary research. Models of subsystems are based on both mathematical...
We consider dynamic trading of a portfolio of assets in discrete periods over a finite time horizon, with arbitrary time-varying distribution of asset returns. The goal is to maximize the total expected revenue from the portfolio, while respecting constraints on the portfolio such as a required terminal portfolio and leverage and risk limits. The revenue takes into account the gross cash generated...
Through the design process of science and education building of the fourth middle school in zhuzhou city, this paper introduces the total plane layout function processing, modeling and detail structure and interior design.
To deal with the constrained communication between Device net of device layer and Ethernet of operation layer in industrial processes, a semi-physical simulation platform, which consists of industrial process control system, constrained communication transmission module and virtual process control object, is designed and proposed in this paper. Considering thoroughly the problems of packet dropout,...
In this paper, a finite-time control method based on fixed-time is developed for attitude stabilization of a rigid spacecraft with external disturbances. In comparison with the existing finite-time techniques based on terminal sliding mode, of which the initial value of system states must be known when estimating the settling time, the proposed fixed-time based sliding mode controller can not only...
For the LOG problems with bounded uncertain parameter existing in the state equation, a adaptive dual control approach is proposed. In this paper, it is assumed that the unknown parameter belongs to a known bounded interval. Firstly, a subdivision for the continuous bounded interval is used. Secondly, based on the subdivision, the dual controller is developed. Furthermore, the controller not only...
An application of an on-line solution verification system for programming competitions is considered in the paper. The system has been developed at in National Research Irkutsk State Technical University and used within the competition events. It has client-server architecture and has been implemented on the base of a cluster using parallel schemes of verification algorithms. The system supports several...
Project-Based Learning (PBL) can significantly motivate students to learn engineering concepts. This paper reports on the experience at Princess Sumaya University for Technology of utilizing PBL to enhance the teaching of wireless communication course. In the project, students are asked to collect real world measurements of cellular towers signal power. The data is then plotted versus distance for...
