Identity and Cultural Transition: Lessons to Learn from a Negative Case Analysis

2020

In this paper, we present a single case study of identity crisis that unfolded in the cultural transition context. Our participant was ‘Jenni’ – a 26 years old female basketball player with the dou...

Making Every "Point" Count: Identifying the Key Determinants of Team Success in Elite Men’s Wheelchair Basketball

2019

Wheelchair basketball coaches and researchers have typically relied on box score data and the Comprehensive Basketball Grading System to inform practice, however, these data do not acknowledge how the dynamic perspectives of teams change, vary and adapt during possessions in relation to the outcome of a game. Therefore, this study aimed to identify the key dynamic variables associated with team success in elite men’s wheelchair basketball and explore the impact of each key dynamic variable upon the outcome of performance through the use of binary logistic regression modelling. The valid and reliable template developed by Francis, Owen and Peters (2019) was used to analyse video footage in S…

Influence of uniaxial pressure and aging on dielectric and ferroelectric properties of BaTiO3ceramics

2013

The effect of uniaxial pressure (0–3000 bar) applied parallel to the AC electric field and aging on dielectric and ferroelectric behavior of BaTiO3 ceramics were investigated. Applying uniaxial pressure leads to a reduction of the peak intensity of the electric permittivity (e) of the polarization as well as of the dielectric hysteresis. The peak intensity of e becomes diffused and shifts to a higher temperatures with increasing the pressure. The electrostrictive coefficient Q 11 and differential permittivity were evaluated from the obtained data. We interpreted our results based on the hardening of the soft-mode and domain switching processes under the action of pressure. The aging effect …

Electric Vehicles and Psychology, Part 2

2021

This paper presents the main psychological attitudes influencing the transition from conventional ICEV to BEV, and it is the continuance of Electric vehicles and psychology, part 1, [1]. This part faces the range anxiety problem, the risk of explosion of batteries, the autonomous silver vehicles and the experience of driving electric vehicles. If the reader is looking for simple answers, the author does not recommend the subsequent reading, since few paradoxes will be solved.

Water Conflict and Water Management in the Middle East

2004

“Water is Life”: this is often forgotten in countries with abundant water ressources. As a ressource it only gains importance once it is in short supply or once its quality declines. In the case of shortage the battle for water becomes inevitable. At the moment we have up to 200 conflicts of border-crossing water systems in the world. The Middle East is considered to be a typical example of this politically significant problem

United in the Commonwealth. The participation of Lithuanian troops in the Zborów battle in 1649

2018

Abstract In 1648, an uprising broke out in Ukraine that belonged to Poland at the time. The war was not successful for the Polish-Lithuanian Commonwealth. The Cossacks and Tartars, who were helping them during the war, surrounded Zbaraż, about whose defense everyone knew in the country. King Jan Kazimierz decided to set out to rescue the besieged fortress. It was decided that not only Polish troops, but also soldiers of Lithuania would set out for Ukraine. Not only state armies, but also private regiments set out to fight. The article discusses the problem of the reasons for the participation of Lithuanians in the war, which was not only due to the provisions of the union, but also to be in…

A Bayesian approach for predictive maintenance policy with imperfect monitoring

2009

In the traditional preventive maintenance policy, the periodic maintenance activities are scheduled on the basis of the a-priori information about the failure behaviour of the population which the component belongs to, by assuming a probability distribution function and by estimating the involved statistical parameters. On the contrary, with the predictive approach, the maintenance activity is scheduled on the basis of the real degradation level of the component. So, it is possible to reduce the failure probability and, at the same time, to use the component for almost all its useful life. For this reason, the predictive maintenance policy makes possible the reduction of the maintenance cos…

Finding Prediction Limits for a Future Number of Failures in the Prescribed Time Interval under Parametric Uncertainty

2012

Computing prediction intervals is an important part of the forecasting process intended to indicate the likely uncertainty in point forecasts. Prediction intervals for future order statistics are widely used for reliability problems and other related problems. In this paper, we present an accurate procedure, called ‘within-sample prediction of order statistics', to obtain prediction limits for the number of failures that will be observed in a future inspection of a sample of units, based only on the results of the first in-service inspection of the same sample. The failure-time of such units is modeled with a two-parameter Weibull distribution indexed by scale and shape parameters β and δ, …

Application of a 1-D numerical model to estimate the sediment transported along a river

2006

Natural rivers tend to adjust their plane shape and longitudinal profile in order to assume a configuration compatible with the changing hydraulic and man-made constraints. The causes of these bed variations are related to changes in independent river channel variables (increase in water discharge, decrease in sediment discharge, etc..) or to changes in river slope. River bed degradation and aggradation, often occurring as result of river morphological changes, modify the longitudinal bed profile of the river and the amount of sediment transported along the river until to reach the outlet. As an example, the construction of river dams produces large morphological consequences: when the stre…
