A Distributed Power Coordination Scheme for Fatigue Load Reduction in Wind Farms

Wind turbines operating in wind farms are coupled by the wind flow. This coupling results in increased turbulence levels for downwind turbines, and consequently higher maintenance costs. In this paper, we consider a scenario where a wind farm is asked to produce less than maximum power. The objective is to minimize fatigue loads on the turbines, while maintaining the desired power production. We s

Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant

Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatme

The mechanism of protein kinase C regulation

Protein kinase C (PKC) is a family of serine/threonine protein kinases that plays a central role in transducing extracellular signals into a variety of intracellular responses ranging from cell proliferation to apoptosis. Nine PKC genes have been identified in the human genome, which encode 10 proteins. Each member of this protein kinase family displays distinct biochemical characteristics and is

European universities and regional economic development – A survey of Nordic universities and their entrepreneurial strategies

This paper reports on a survey of the 20 largest Nordic universities, 12 Humboldtian type universities and 8 technical universities, and their espoused objectives and strategies regarding their entrepreneurial and regional innovation role. The study is based on archival data; public documents issued by each university, and interviews with university top managers responsible for the third mission.

Test of three different audio-haptic navigation tools

The present paper presents a continuation of the work on navigational tools studied in two pilot tests [1], [2]. To further test the tools most popular in these pilot tests, as well as investigate possible influences on the spatial perception by different
