The performance of quasi-static cyclic loading in terms of peak lateral load capacity, ductility and crack patterns was investigated. The influence of using the composite fabrics on continuity of joints was also considered. The results were presented in terms of load-deflection curves and hysteretic energy loops. It was found that the behavior of retroffited joints is significantly improved in terms of moment bearing capacity, ductility, axial load, and drift.
Growing electricity demands combined with drastic environmental changes have led to the penetration of renewable distributed generations (DGs) close to the load via the adoption of microgrids. However, the intermitten...

The electrical system shall be designed economically for continuous and reliable services, safely to personnel and equipment, ease of maintenance and operation, minimum power losses, protection of equipment mechanically, interchangeability of equipment and addition of the of the loads. In order to achieve the above goals and obtain the desired results, a scientific study based on different theories and practical experiences will be needed. In this study, the power supply of Transnet Pipeline Terminal 2 (TM2) petroleum refinery in Heidelberg, the criteria and methods of designs of normal networks, electrical equipment and protection of the system will be discussed and investigated. A single line diagram will be presented as the outcome of the design. The single line diagram includes 88kV, 11kV and 400V voltage levels. In the second phase of the design single line diagram is consequently simulated by the ETAP software. The study will cover the following: load flow, short circuit current and motor starting. The intention of this study is to create solution in different ways, electrical loads should be categorized in this energy industry as well as energizing these loads by a stable power supplies. In addition the key role of the short circuit impedance of the transformers in control of the short circuit will be presented. Furthermore the selection procedure of the electrical equipment and accessories including cables, transformers, circuit breaker, relays, and etc. are presented. The following factors such as the size of equipment, losses and voltage drops will be checked by load flow study. A comprehensive study of the short circuit current calculations is implanted and can be observed how the system can be checked by the results of this study. In the dynamic study of the system, the biggest motor starting is simulated and the impacts of the voltage dips due to starting of this motor on the other running motors are shown. Since numerous types of equipment on one hand
Capillaries were believed to be the sole source of O2 supply to tissue. However, the recent studies have demonstrated a longitudinal PO2 drop in arterioles, suggesting the possibility of O2 supply from arterioles. Fur...

In this paper we propose the use of a lattice based second order infinite impulse response (IIR) notch filter with a simplified adaptation algorithm for removal of power line frequency from ECG signals. The performance of this filter is better as compared to a second order infinite impulse response (IIR) notch filter for a real time ECG recording systems where the frequency of line varies over a narrow range about 50 Hz.
Unified Virtual Oscillator Control (uVOC) is a time-domain control law that combines grid-following control (GFL) and grid-forming control (GFM). Despite extensive stability analysis of uVOC and similar control scheme...
