Background: The proportion of households that use tank rainwater as their main source of drinking water is similar to the proportion using reticulated public mains supplies in South Australia. However, little is known about risk to health from consuming rainwater. Aims: (1) To determine whether the risk of gastroenteritis among children who drank tank rainwater differed from that of children wh...
The paper extends research on fixed-pie perceptions by suggesting that disputants may prefer proposals that are perceived to be equally attractive to both parties (i.e., balanced) rather than one-sided, because balanced agreements are seen as more likely to be successfully implemented. We test our predictions using data on Israeli support for the Geneva Accords, an agreement for a two state sol...

Dans le cadre l’optimisation performances, sont habituellement testés au laboratoire et/ou sur terrain. Au laboratoire, ergomètres manivelles (EM)...
دنباله های تولیدی توسط توربین ها و اثرات ناشی از ناهمواری های زمین باعث کاهش سرعت باد در یک مزرعه بادی می شوند. در چیدمان بهینه توربین ها که با هدف تولید بیشترین انرژی و صرف کمترین هزینه انجام می شود همواره سعی می شود تا از قرارگرفتن توربین در این نواحی که باعث کاهش بازده توربین و قرارگرفتن آن در معرض اغتشاشات جریان و کاهش طول عمر توربین می شود جلوگیری شود. با مدل سازی عددی یا انجام آزمایش به م...
For the use of the mains networks as high speed data path for Internet, voice and data services carrier frequencies within the range from 500 kHz up to 20 MHz must be considered. The development of suitable communication systems and the planning of power line communication networks requires measurement-based models of the transfer characteristics of the mains network in the abovementioned frequ...
In the paper the topology of a new three-phase three-switch three-level PWM rectifier system is derived based on the basic structure of a DC-to-DC SEPIC converter. The system is characterized by full controllability of the power flow (independent of the level of the output voltage) and by a sinusoidal mains current shape in phase with the mains voltage. The operating principle of the converter ...
Well functioning water networks are essential to the sustainability of a community. Large transmission and distribution water mains are often the most sensitive components of these networks since their failure can be catastrophic. Furthermore, due to the high cost of these pipes, the system does not usually provide redundancy to enable decommission for maintenance and rehabilitation. Hence, fai...
