In this paper the effect of presence of wind farms on relay coordination at fault condition and transient response at reclosing condition is studied. Wind farms as one of the important distribution generations (DGs) are so effective on overcurrent relay coordination in power systems. As well as Wind farms cause to severe oscillations on voltage, power and frequency in power system after reclosi...

In spite of the great advancement in the diagnosis, treatment and control programs of tuberculosis during the past decades, bovine tuberculosis still represent an imminent threat to the public and considerable obstacles for development of bovine industry especially in developing countries [1]. All animal species and humans of all age groups are susceptible to the disease. Mycobacterium bovis, a...

This paper presents an original study on the generated torque ripples of phase commutation in the Four-Switch, Three-Phase Inverter (FSTPI) Brushless DC (BLDC) motor drive which is suitable for low cost applications. Analytic values of torque ripple and commutation duration are obtained for different operation conditions. Moreover, limitation on the speed range operation caused from splitti...

In this article, a novel nonlinear droop control method is proposed for three-phase grid-supporting inverters that rigorously guarantee limited rms value of the inverter current and closed-loop system stability under both normal grid conditions balanced voltage sags. Contrary to traditional dq frame approaches align output with d-axis, controller aligns d-axis resulting in desired limitation de...

Supplying uninterrupted and high quality electric power to the customer is a priority in the current power systems. Electricity, as a commodity, represents the motive force of modern society and its deprivation causes costly losses for essential parts of the economy in any region. This thesis performs a reliability study on a fictional test network, employing several techniques to control fault...

Current approaches in Digital .Humanities tend to ignore a central aspect of any hermeneutic introspection: the intrinsic vagueness of analyzed texts. Especially when dealing with historical documents neglecting vagueness has important implications on the interpretation of the results. In this paper we present current limitation of annotation approaches and describe a current methodology for an...

Radiation exposure causes cancer and non-cancer health effects, each of which differs greatly in the shape of the dose-response curve, latency, persistency, recurrence, curability, fatality and impact on quality of life. In recent decades, for dose limitation purposes, the International Commission on Radiological Protection has divided such diverse effects into tissue reactions (formerly termed...

The overarching issue in statistical disclosure limitation is the compromise between data utility and data privacy. While data providers, such as government or nongovernment agencies, often give privacy guarantees to those whose data they collect, too much obfuscation dilutes the data’s usefulness to the public and researchers. Researchers concerned with statistical disclosure limitation study ...
