Purpose The importance of events for marginalised groups has largely been overlooked within tourism, hospitality and event studies. purpose this study is to address gap, emphasising the positive outcomes power relationships rather than negative, which have traditionally focus in Design/methodology/approach investigated eight indigenous ethnic minority groups, rural women, disabled people senior...

Costs of power quality disturbances (interruptions, voltage sags, harmonics, surges etc.) are very significant and have the highest impact on industry. In order to minimize those costs, it is necessary to analyze the electrical system and then try to determine possible future problems. Only after that, it is possible to improve the system in the right way. HEP d.d. – (Croatian electricity compa...

Dynamic epistemic logic as viewed by Baltag, Moss and Solecki (BMS) and propositional dynamic logic (PDL) offer different semantics of events. On the one hand, BMS adds dynamics to epistemic logic by introducing so-called event models as syntactic objects into the language. On the other hand, PDL has instead transition relations between possible worlds. This last approach allows to easily intro...

This paper reports stochastic properties of renewable wind and solar energy resources by studying their conditional probability distribution functions (cpdf) in different time lags. The empirical results are obtained for data of global horizontal irradiance measured by a single sensor and the power output of a single wind turbine, as well as for an averaged solar sensor field and an aggregated ...

In power systems, a connected topology is created to increase reliability and economic performance. Increasing dimensions of power systems on the one hand and the need to continuously monitor power systems for secure operation on the other challenge the evaluation of power system security. In such conditions, due to economic conditions and considering the fast growth of consumers in a power sys...

An accurate time-frequency representation (TFR) can provide useful information in non stationary data analysis and processing. The traditional methods like short-time Fourier transform (STFT) and wavelet transform (WT) based TFR approaches are leads to a tradeoff between time and frequency resolution. A recently proposed synchrosqueezing transform (SST), which is an extension of the WT, has bee...

conclusions these results emphasize that an inappropriate decision making process pattern in a family has a significant effect on deviant behavior in adolescents. the fathers’ parenting is more strongly linked to their sons’ delinquency. so, family power structure and parent-child relationship can be considered in therapeutic interventions (prevention and treatment) for adolescents’ delinquency...

Recently electronic tap-changer has received more attention due to its quick response, better performance and simpler maintenance compared to the mechanical tap-changer. This paper presents the capability of the distribution transformer equipped with an electronic tap-changer for improving power quality. At this end, the analytical computation for determining the compensating limit of electroni...
