This with the integration of distributed generation (DG) to meshed distribution systems, the operating time of the protective system becomes a major concern in order to avoid nuisance DG tripping. This paper proposes a new tripping characteristic for directional overcurrent relays (DOCRs) that can achieve a higher possible reduction of overall relays operating time in meshed distribution networ...

it is not clear what factors determine divergent outcomes of infections caused by h. pylori . in the present study, the protein profiles of different strains of h. pylori, isolated from three groups of patients with ulcerative disease, non-ulcerative gastritis and cancer disease, were analyzed using 1dsds-page. the patterns of different h. pylori strains were highly divergent. about 30.76% (7 b...

The problem of slow drilling in deep shale formations occurs worldwide causing significant expenses to the oil industry. Bit balling which is widely considered as the main cause of poor bit performance in shales, especially deep shales, is being drilled with water-based mud. Therefore, efforts have been made to develop a model to diagnose drilling effectivity. Hence, we arrived at graphical cor...

Many large-scale surveys measure subjective well-being (SWB) through a single survey item. This paper takes advantages of response time data to explore the relation between time taken to answer a single SWB item and the reliability and validity of answers to this SWB item. We found that reliability and validity of answers to the SWB item are low for fast respondents aged 70 and above and slow r...

Parenting style experienced during childhood has profound effects on children's futures. Scales developed in other countries have never been validated in the Tibetan context. The present study aimed to examine the construct validity and reliability of a Tibetan translation of the 23-item short form of the Egna Minnen Beträffande Uppfostran [One's Memories of Upbringing] (s-EMBU) and to test the...

One special subalgebra of the algebra of fuzzy truth values is the set of those elements that take only 0 and 1 as values. This subalgebra is in one-to-one correspondence with the subsets of the unit interval, but the operations do not correspond to ordinary union and intersection. The automorphisms of this subalgebra are studied here, resulting in showing that the subobjects corresponding to n...
