Numerical Modeling of Mold Filling and Curing in Non-Isothermal RTM Process (RESEARCH NOTE)
(Materials and Energy Research Center, 2004-11-01)Resin Transfer Molding (RTM) is a composite manufacturing process. A preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. In this paper, a model is developed to predict the flow pattern, ...

Analysis and Design of a Simple Surge Tank (RESEARCH NOTE)
(Materials and Energy Research Center, 2004-11-01)In a hydroelectric power plant or in a pumping station in order to avoid sudden large increase of pressure due to instantaneous valve closure sometimes a surge tank is installed. The height of surge tank is designed by the ...

Simulation of Ideal External and Internal Flows with Arbitrary Boundaries Using Schwarz Christoffel Transformation
(Materials and Energy Research Center, 2004-11-01)The flow field, velocity and pressure coefficient distribution of some 2-D ideal flows are presented. Conformal mapping is used to simulate two-dimensional ideal flow for a variety of complex internal and external ...

Ultra-Widband Distributed Amplifier Using Loss Compensation Technique on Both Input and Output Circuit
(Materials and Energy Research Center, 2004-11-01)In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s ...

Control of Multivariable Systems Based on Emotional Temporal Difference Learning Controller
(Materials and Energy Research Center, 2004-11-01)One of the most important issues that we face in controlling delayed systems and non-minimum phase systems is to fulfill objective orientations simultaneously and in the best way possible. In this paper proposing a new ...

Determination of Principal Permeabilities in Two-Dimensional Fissured Rocks Using Permeability Circle (TECHNICAL NOTE)
(Materials and Energy Research Center, 2004-11-01)Among the many parameters affecting the design of hydraulic structures on fissured rocks are orientation of principal permeability axes and degree of anisotropy of fissured rocks. Geological explorations rarely provide ...
