Experimental Update of the Overtopping Model Used for the Wave Dragon Wave Energy Converter
Parmeggiani, Stefano; Kofoed, Jens Peter; Friis-Madsen, Erik - In: Energies 6 (2013) 4, pp. 1961-1992
An overtopping model specifically suited for Wave Dragon is needed in order to improve the reliability of its … performance estimates. The model shall be comprehensive of all relevant physical processes that affect overtopping and flexible to … formulation suited for 2D draft-limited, low-crested structures, in order to include the effects on the overtopping flow of the …

Experimental Study Related to the Mooring Design for the 1.5 MW Wave Dragon WEC Demonstrator at DanWEC
Parmeggiani, Stefano; Kofoed, Jens Peter; Friis-Madsen, Erik - In: Energies 6 (2013) 4, pp. 1863-1886
The paper presents the results of an experimental study identifying the response of a 1.5 MW Wave Dragon to extreme conditions typical of the DanWEC test center. The best strategies allowing for a reduction in the extreme mooring tension have also been investigated, showing that this is possible...

Comparative review of urban geometric parameters and their uses in outdoor thermal environment studies
Zhang, Jian; Zhang, Fan; Jiang, Lin; Guo, Wei; Cao, Qi; … - In: Journal of urban management 13 (2024) 3, pp. 541-552
A significant proportion of the world's population is currently experiencing heat stress. This results from the effects of global warming, urban heat islands (UHIs), and the growth of urban populations. Researchers have investigated multiple strategies to address this problem. It has been found...

Field Surveys of Non-Residential Solar Water Heating Systems in Taiwan
Lin, Wei-Min; Chang, Keh-Chin; Liu, Yi-Mei; Chung, Kung-Ming - In: Energies 5 (2012) 2, pp. 258-269
To develop indigenous alternative and renewable energy resources, long-term subsidy programs (1986–1991 and 2000–present) for solar water heaters have been enforced in Taiwan. By the end of 2010, the total installed area of solar collectors had exceeded 2 million square meters. However, over...

Competition and market strategies in the Swiss fixed telephony market
Balmer, Roberto E. - 2015
Fixed telephony has long been a fundamentally important market for European telecommunications operators. The liberalisation and the introduction of regulation in the end of the 1990s, however, allowed new entrants to compete with incumbents at the retail level. A rapid price decline and a...

Does disagreement amongst forecasters have predictive value?
Legerstee, Rianne; Franses, Philip Hans - 2010
Forecasts from various experts are often used in macroeconomic forecasting models. Usually the focus is on the mean or median of the survey data. In the present study we adopt a different perspective on the survey data as we examine the predictive power of disagreement amongst forecasters. The...
