Effective Design of a 3×4 Two Dimensional Distributed Amplifier Based on Gate Line Considerations

In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...

Secure Urban Design in Terms of Passive Defense Approach; Analytical Considerations for Improving Form-based Characteristics in Iranian Cities

Behavioral Considerations in Developing Web Information Systems: User-centered Design Agenda

The current paper explores designing a web information retrieval system regarding the searching behavior of users in real and everyday life. Designing an information system that is closely linked to human behavior is equally important for providers and the end users.  From an Information Science point of view, four approaches in designing information retrieval systems were identified as system-...

3-D RF Coil Design Considerations for MRI

High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by ele...

Thermal Design Considerations and Performance Evaluation of Cryogenic Tube in Tube Heat Exchangers

Heat exchangers are the most important equipment in refrigeration processes. Design and modeling of heat exchangers operating at low temperatures are different from other regular heat exchangers. This study includes two sections. In the first section, design and modeling considerations needed for evaluating the real thermal behavior of heat exchangers at low temperatures were discussed. The...

Design of a reliable supply chain network with responsiveness considerations under uncertainty: case study of an Iranian tire manufacturer

This paper proposes a bi-objective reliable supply chain network design that immunizes the network against different sources of uncertainties. In this regard, scenario based stochastic programming method is applied to model different disruption scenarios affecting accurate performance of network stages. Also, reliable and unreliable facilities are suggested for lessening vulnerability of networ...
