Wheel wear has been a concern in the railway for several decades. Studying the form change of the wheel/rail contacts in particular railways consisting of sharp curves helps to identify the risk of severe or catastrophic wear to minimize maintenance costs in order to be competitive in the transportation business. In this paper, the wheel/rail contact was studied on the particular railways. The ...

OBJECTIVE We wished to examine whether resilience might be a protective factor in relation to suicidal behavior. METHOD To do this resilience was examined in relation to childhood trauma, a well established risk factor for suicidal behavior, in two samples. In a preliminary sample 20 abstinent substance abuse patients who had attempted suicide were matched for age and their score on the Child...

OBJECTIVE The Childhood Trauma Questionnaire (CTQ) is perhaps the most widely used and well-studied retrospective measure of childhood abuse or neglect. This study tested the initial reliability and validity of a Korean translation of the Childhood Trauma Questionnaire (CTQ-K) among non-psychotic psychiatric outpatients. METHODS The CTQ-K was administered to a total of 163 non-psychotic psych...

Nowadays every business is using different quantitative measures and techniques to assess peiformance of their products! services. It is well known that different manufacturing processes very often manufacture products with quality characteristics that do not follow normal distribution. In such cases, fitting a known non-normal distribution to these quality characteristics would lead to erroneo...

This paper proposes two quantitative criteria for removing railroad wheels from service, based on real-time structural health monitoring trends that are developed using data collected from trains while in-service. The data is collected using Wheel Impact Load Detectors (WILDs). These impact load trends are able to distinguish wheels with a high probability of failure from high impact wheels wit...

The present study examines the internal consistency and factor structure of the Spanish version of the Childhood Trauma Questionnaire-Short Form (CTQ-SF) and the association between the CTQ-SF subscales and parenting style. Cronbach's α and confirmatory factor analyses (CFA) were performed in a female clinical sample (n = 185). Kendall's ι correlations were calculated between the maltreatment a...

Minimizing waiting time for tasks waiting in the queue for execution is one of the important scheduling criteria which took a wide area in scheduling preemptive tasks. In this paper we present Changeable Time Quantum (CTQ) approach combined with the round-robin algorithm, we try to adjust the time quantum according to the burst times of the tasks in the ready queue. There are two important bene...
