While active flow control is an established method for controlling flow separation on vehicles and airfoils, the design of the actuation is often done by trial and error. In this paper, the development of a discrete and a continuous adjoint flow solver for the optimal control of unsteady turbulent flows governed by the incompressible Reynoldsaveraged Navier-Stokes equations is presented. Both a...
Precise fluid flow control is one of the most important aspects of many chemical processing systems, both reactive and analytical. Recent research has led to a sensor capable of very precisely measuring mass flows up to 1g/h, based on the Coriolis principle. However, applying such a measurement in a flow control system is not yet possible, as valves capable of regulating such small flows do not...
Among the various species of small pelagic fish, Sardinella sindensis (Day ,1878) has high economic and ecological importance and is one of the most important species exploited by fishermen. In recent years, the catch rate of this species has increased, and due to the limited data available on its stock in southern waters, it is not possible to use models based on the complementary data to asse...
abstract the aim of the present study is to explore the impact of the cognitive reading strategy instruction on learners reading self-efficacy and their reading achievement. in order to fulfill this purpose, from 120 participants, 90 intermediate efl learners as an experimental group were chosen from three different educational settings namely, yazd university, yazd science and art un...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
1 This work has been partially supported by a grant from the German Ministry for Research and Education (BMB+F) within the project “Communication and Mobility by Cellular Advanced Radio (COMCAR)” and by the European Commission within the IST project “Dynamic Radio for IP-Services in Vehicular Environments (DRiVE)”. Abstract Future wireless communication systems will be characterised by an integ...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
