The impact of basic system uncertainties

چکیده
LS I +61 303 has been recently detected as a periodic γ-ray source by the Major Atmospheric Imaging Cerenkov (MAGIC) telescope. A distinctive orbital correlation of the γ-ray emission was found. This work shows that the range of uncertainties yet at hand in the orbital elements of the binary system LS I +61 303 as well as in the possible assumptions on the stellar wind of the optical companion play a non-negligible role in the computation of opacities to high energy processes leading to γ-ray predictions. The geometry influence on the propagation and escape of γ-ray photons is explored. With this study at hand, we analyse the results of a pulsar wind zone model for the production of γ-rays and compare it with recent MAGIC observations. Subject headings: X-ray binaries (individual LS I +61 303), γ-rays: observations, γ-rays: theory

Reliability analysis of a robotic system using hybridized technique
In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...
متن کاملOptimal Reconfiguration in Smart Distribution Network in the Presence of DG Resources under Uncertainties
Due to the growth and expansion of cities and the unchanged distribution network, an important issue for electricity distribution companies is customer satisfaction with the quality of received power. It is clear that with the expansion of load centers, the amount of line power flow increases, that creates problems such as voltage drop and increased losses. Distribution network reconfiguration ...

In this paper, the synchronization of a new hyperchaotic complex system based on T-S fuzzy model is proposed. First, the considered hyperchaotic system is represented by T-S fuzzy model equivalently. Then, by using the parallel distributed compensation (PDC) method and by applying linear system theory and exact linearization (EL) technique, a fuzzy controller is designed to realize the synchron...
متن کاملStochastic Congestion Management Considering Power System Uncertainties
Congestion management in electricity markets is traditionally done using deterministic values of power system parameters considering a fixed network configuration. In this paper, a stochastic programming framework is proposed for congestion management considering the power system uncertainties. The uncertainty sources that are modeled in the proposed stochastic framework consist of contingencie...
