Abstract Prediction of gas well deliverability is important for reservoir management. Conventional flow after flow, isochronal or modified tests are common methods calculation deliverability. Single-point test using Vogel-type dimensionless inflow performance relationships (IPR) was also proposed to overcome the need multi-point tests. However, analysis field data showed that existing IPR corre...

closed-end furrows are commonly used to irrigate crop in northern part of china. the irrigation performance of furrow in this area is often low. the objectives of this paper are to verify reliability of infiltration parameters and manning roughness estimated with sipar_id software and present an optimized method for design of closed-end furrow system. the study consisted of field experiments an...

Dual turbocharger turbine is fed by an unequal out-of-phase mass flow charge almost all the time which have significant effects on its performance parameters and flow phenomena which are not well known. Besides fully understanding the flow behavior in the radial turbine suffers from lack of detailed information about the secondary flows. This article studies the secondary flow structure within ...

Marine and hydrokinetic (MHK) technology performance testing in the laboratory and field supports the US Department of Energy’s MHK program goals to advance the technology readiness levels of MHK machines, to ensure environmentally responsible designs, to identify key cost drivers, and to reduce the cost of energy of MHK technologies. Laboratory testing results from scaled model machine testing...

In a knowledge-intensive industry such as information technology, human resource management plays a central role in the success of software firms. This study takes a firm-level analysis and examines the effects of the human resource inflows and outflows on software firm performance. Moreover, we investigate how the specific human capital variables (e.g. education, experience) embedded in the hu...
