Mechanical loads considerably impact wind turbine lifetime, and a reduction in this load is crucial while designing controller for maximum power extraction at below-rated speed (region II). A trade-off between energy minimum on the drive train shaft big challenge. Some conventional controllers extract with cost of high fluctuations generator torque transient load. Therefore, to overcome above i...

This paper presents basic principles of a scenario approach application to the problem of optimal development of social economic systems. The formalized description of scenario of system sustainable development is introduced and synergetic and attractive scenarios are examined. The modes providing stable and safe development of social economic system are investigated for synergistic scenarios, ...

the oil refining industries are using a number of demulsifiers for dewatering and desalination of crude oil but experience has shown that universal demulsifiers can not be produced. each kind of water in oil (w/o) emulsion requires specific by composition demulsifier. in practice, synergetic effect of the interaction between different types of demulsifiers is often sought. for dewatering the w...

There are several questions about hydration in terminal care: the discussion about whether or not, and if yes how much and by which route? Shows hydration any benefits regarding survival and symptom-control? Are there side-effects of hydration? The article tries to give an overview rather than a review over the literature of the last 10 years since there is no evidence about this topic. Three s...

In this commentary, we evaluate the methodology of Udell, Dorey, and Wynne's (Learning & Behavior, in press) experiment in controlling for environmental factors and argue that their conclusion is not supported. In particular, we emphasise that comparative studies on dogs and wolves need to ensure that both species enjoyed the same rearing history, are comparable in age, and have the same experi...

Economists were interested in economic stabilization policies as early as the 1930’s but the formal applications of stability theory from the classical control theory to economic analysis appeared in the early 1950’s when a number of control engineers actively collaborated with economists on economic stability and feedback mechanisms. The theory of optimal control resulting from the contributio...

A distributed vision network is proposed to tackle industrial packaging inspection. The system consists of independent networked inspection stations able to address efficiently parallel inspection tasks such as product identification, character verification, tag inspection and content & packaging quality control at a high production speed. Existing and innovative inspection algorithms such as s...
