Education as a means to world peace : the case of the 1974 UNESCO Recommendation
2010
Liberal Institutionalism
2020
The application of liberal institutionalism to peacekeeping has shed light on several important questions regarding why member states support the deployment of a specific operation, how they build support for their position, whether domestic preferences influence their strategies in the Security Council and why they volunteer troops for peacekeeping. Sponsorship records have proven to be a useful sourse for researching coalition-building on peacekeeping.
Modeling the probability distribution of peak discharge for infiltrating hillslopes
2017
Hillslope response plays a fundamental role in the prediction of peak discharge at the basin outlet. The peak discharge for the critical duration of rainfall and its probability distribution are needed for designing urban infrastructure facilities. This study derives the probability distribution, denoted as GABS model, by coupling three models: (1) the Green-Ampt model for computing infiltration, (2) the kinematic wave model for computing discharge hydrograph from the hillslope, and (3) the intensity-duration-frequency (IDF) model for computing design rainfall intensity. The Hortonian mechanism for runoff generation is employed for computing the surface runoff hydrograph. Since the antecede…
Runoff coefficients to predict peak discharge at hillslope scale: A small contribution to theoretical hydrology
2018
The science of hydrology holds a central role in the field of environmental Earth science, being intimately connected to meteorology, climatology, hydrogeology and ecology. In particular, the knowledge of hillslope hydrology is fundamental for understanding the flood phenomenon, for predicting the peak discharge and its probability distribution, which is necessary in many practical applications (design of hydraulic structures, urban, extra-urban planning, etc.). Using different approaches, there have been a multitude of studies on the hydrologic response at hillslope scale. One approach for deriving the hillslope response utilizes, in a distributed form, the differential equations of unstea…
Strong experiences of music in university students
2009
Research in Sweden has recently defined and explored the concept of strong experiences of music, which had been hitherto ignored by much research in the psychology of music and emotion. From a large-scale study of over 900 adults, Gabrielsson and Lindström Wik (2003) found that strong experiences of music included positive and negative responses to music, and could occur with any genre of music. The current research explores the generalisability of the strong experiences of music studied by Gabrielsson and Lindström Wik with a university student population in England, and compares the efficacy of the methods of analyzing accounts. 64 undergraduate students who had elected to take a music ps…
Optimization of BESS Capacity Under a Peak Load Shaving Strategy
2018
Battery energy storage systems (BESSs) are becoming increasingly competitive in the global energy landscape, thanks to the strong cost reduction that has taken place in recent years and it is expected to continue in the next future. Among the many benefits BESSs can provide, time shifting can be exploited by electricity consumers to save on the electricity bill, charging the storage during the off-peak hours and discharging when the cost of electricity is high. This paper describes a simple procedure to optimize the BESS capacity under a peak load shaving strategy, in presence of a time-of-use (TOU) electricity rate, able to guarantee, at the same time, the flattest daily power diagram and …
DEMAND Project: A Peak Load Shaving Strategy for End-User Consumers
2018
Battery energy storage systems (BESS) are becoming increasingly widespread in modern power systems, thanks to the important benefits they can provide to the electricity grid. Indeed, BESS can be used in time shifting applications, storing energy during off-peak periods and discharging during peak times (when the cost of electricity is high). When BESS are used for peak shaving purposes, they also contribute to relieve peak demand charges, thus ensuring a saving for the consumers. This paper describes a peak load shaving strategy defined within the DEMAND project. The strategy is able to guarantee the flattest daily power diagram and the maximum benefit for the electricity consumers, reducin…
Iterative Learning Applied to Hydraulic Pressure Control
2018
This paper addresses a performance limiting phenomenon that may occur in the pressure control of hydraulic actuators subjected to external velocity disturbances. It is demonstrated that under certain conditions a severe peaking of the control error may be observed that significantly degrades the performance of the system due to the presence of nonlinearities. The phenomenon is investigated numerically and experimentally using a system that requires pressure control of two hydraulic cylinders. It is demonstrated that the common solution of feed forwarding the velocity disturbance is not effective in reducing the peaking that occurs as a result of this phenomenon. To improve the system perfor…

Dire institutionnel et espaces de langage - le cas de l'Algérie - Essai d'une sémio-didactique
1992
This thesis is 1) an discourse analysis of the institution' texts (Algeria, in the eighties) + analysis of the young people in secondary school (part I) ; 2) a semiotic analysis of spaces in Algeria (country, village, secondary school). The results : we showed many contraints in a collective speech, through 2 dominant themas : time, action ; and 2 recessive themas : subject (speaker), mirror. So, education and didactic perspective are useful.
