This paper presents an alternative approach using the differential logic associated to Artificial Neural Networks (ANNs) in order to distinguish between inrush currents and internal faults in the protection of power transformers. The Alternative Transients Program (ATP) has been chosen as the computational tool to simulate a power transformer under fault and energization situations. The Radius ...

Surge protective device is a part of internal lightning protection and it crucially to divert the certain amount of surges to the ground before the protected load able to handle. Therefore, this paper studying the enhancement of SPD through the effect of adding a filter in hybrid surge protection circuit using simulation modeling. Ordinarily, filter is used as in eliminating noises in certain a...

While general-purpose processor based systems are built to enforce memory protection to prevent the unintended sharing of data between processes, current systems built around reconfigurable hardware typically offer no such protection. Several reconfigurable cores are often integrated onto a single chip where they share external resources such as memory. While this enables small form factor and ...

Section 20.1204 of 10 CFR Part 20, "Standards for Protection Against Radiation," requires that each licensee, when required by 10 CFR 20.1502, take suitable and timely measurements of quantities of radionuclides in the body, quantities of radionuclides excreted from the body, concentrations of radioactive materials in the air in the work area, or any combination of such measurements as may be n...

In this paper, we consider vulnerable systems which can have different states corresponding to different combinations of available elements composing the system. Each state can be characterized by a performance rate, which is the quantitative measure of a system’s ability to perform its task. Both the impact of external factors (attack) and internal causes (failures) affect system survivability...

In this work, a new approach applied to digital differential protection relay for a large power transformer is presented. First, the Fourier sine and cosine coefficients required for fundamental, second, third and fifth harmonic extraction have been determined using rectangular transfer technique. Then, these harmonics have been used in harmonics restrain and blocking techniques applied to diff...

Skin cancer, the most common type of cancer worldwide, has been linked to overexposure ultraviolet radiation (UVR) without protection. As skin is a preventable there pressing need adopt health-promoting behaviors early in life. The Sun Exposure and Protection Index (SEPI) an instrument for evaluating adults’ sun exposure habits propensity increase protection with widely accepted validity reliab...

The objective of this study is to assess the effects of home country investor protection and ownership structure on the Sarbanes-Oxley Act (SOX)–mandated internal control deficiency (ICD) disclosures by foreign firms that are listed on the U.S. stock exchanges (hereafter referred to as cross-listed firms). Our research question is important for two reasons. First, cross-listed firms have become...

a specimen of an ascomycetous fungus collected during a field trip was identified as gymnoascus baran. soil samples collected from 0-20 cm depth were studied for isolation of fungi using a soil dilution plate method. based on the morphological and molecular characters the specimens were identified as gymnoascus reesii. genomic dna was extracted and a nuclear rdna region, containing the internal...

This Article will focus on one particular accession condition that is illustrative of this phenomenon, namely, the protection of minorities. The Copenhagen criteria encompass the “respect for and protection of minorities” as one of the conditions for acceding to the Union, but the Treaty on European Union (”TEU”) does not explicitly mention the protection of minorities as one of the EU’s princi...
