In this study, the effect of management entrenchments on the speed of cash holding adjustment in Iran has been investigated. After designing the management entrenchment evaluation indicators, the transaction information was collected from the Stock Exchange in the five-year period of 2011-2015. The statistical sample consists of 155 companies selected by systematic deletion method. In this rese...

Time is an essential measure of performance in software development because time delays tend to fall directly to the bottom line. To address this issue, this research seeks to distinguish time-based software development practices: those managerial actions that result in faster development speed and higher productivity. This study is based upon a survey of software management practices in Wester...

The study examined whether a test of walking speed provides similar predictive information on mortality risk as does a summary measure of lower body function. Data were from the Hispanic Established Population for the Epidemiologic Study of the Elderly database and included Mexican Americans aged 65 years or more (1993– 2000). Primary measures included a short physical performance battery, a te...

This work gives a short overview of the role that model predictive control has in the development of the advanced wind turbine control algorithms. The advantages of model predictive control compared to conventional controllers involved in wind turbine control are outlined. Wind turbine model predictive speed controller based on identified piecewise affine discrete-time statespace model is desig...

Hedenström and Alerstam (Hedenström and Alerstam, 1995) argued that different optimal air speeds can be identified for a migrating bird depending on whether the ‘currency’ that the bird is trying to maximise is distance per unit fuel energy used, average speed over one or several flight stages and stopovers, or various other possibilities. On the other hand, Alerstam and Hedenström (Alerstam an...

How should a vehicle he driven to minimise fuel consumption? In this paper we consider the case where a train is to be driven along a straight, level track, but where speed limits may apply over parts of the track. The journey is to be completed within a specified time using as little fuel as possible. For a journey without speed limits, the optimal driving strategy typically requires full powe...

telemedicine has changed the way of health care. it is an indispensable tool in the hands of doctors to accelerate and facilitate the process of data interchange. wireless networks consist of small nodes with communications capabilities. development of wireless networks of telemedicine system is highly demanded since these networks promise a wide range of potential applications. in this paper t...
