Abstract The power output of a straight-bladed H-rotor Darrieus vertical axis wind turbine (HDVAWT) is explored in this article. comparisons are performed between the NACA0018 airfoil and series Kline Fogelman modified airfoils. computational fluid dynamics findings first cross-checked with experimental data, processes validated as consequence. Then, CATIA, 12 airfoils were constructed by modif...

Abstract For a good functioning of the activities carried out within research institutions both at managerial level and for fulfilling technical requirements, we aim to determine aerodynamic characteristics standard profiles used in aerospace field by testing subsonic tunnel. We also intend conduct study based on numerous experimental tests performed wind tunnels that can be compared actual sca...

0018-9251/95/$4.00 @ 1995 IEEE In numerous practical situations a large array of sensors is required, especially for improving the system ability to detect and track moving sources. However, the array performances are strongly affected by the lack of stationarity of the impinging signals which is due to multiple factors like time-varying source models, medium, and array. Here, we are chiefly co...

The New Zealand Commerce Commission is currently undertaking an enquiry into the terms “light” and “mild” on tobacco products. This is an important issue from a public health and a consumer rights perspective. However, we fear that focusing only on the descriptor as a potentially misleading method of communicating about the product to consumers is inadequate, and that the review should encompas...

Phakopsora pachyrhizi is an obligate pathogen that causes Asian soybean rust. Asian soybean rust has an unusually broad host range and infects by direct penetration through the leaf cuticle. In order to understand the early events in the infection process, it is important to identify and characterize proteins in P. pachyrhizi. Germination of the urediniospore is the first stage in the infection...

Examples include the Apache Software Foundation, the Eclipse Foundation, and the Gnome Foundation. There are many reasons why software development firms join and support a foundation. One co...

0018-9251/00/$10.00 @ 2000 IEEE Use of a fixed threshold for the detection of radar signals results either in a degradation in the detection performance or an excessive increase in the FAR (false alarm rate), as a consequence of the variation in the background noise power. Therefore, using an adaptive threshold with the CFAR (constant FAR) property is unavoidable in most radar and automatic det...

Mindfulness-based stress reduction (MBSR) has produced behavioral, psychological, and physiological benefits, but these programs typically require a substantial time commitment from the participants. This study assessed the effects of a shortened (low-dose [ld]) work-site MBSR intervention (MBSR-ld) on indicators of stress in healthy working adults to determine if results similar to those obtai...
