The purpose of the present research is to investigate the effective channels of the monetary transmission mechanism in Iran. To do so, we devised a New Keynesian Dynamic Stochastic General Equilibrium Model. In our model, the different types of nominal rigidities are introduced beside all the related structural equations, which are extracted and linearized around a steady state point. Furthermo...

Impedance pump is a simple valveless pumping mechanism, where an elastic tube is joined to a more rigid one; a periodic asymmetrical pinching on the elastic tube will produce a unidirectional flow. This pumping concept offers a low energy, low noise alternative at both micro and macro scales. This paper describes an experimental investigation of the performance of a two-stage, open loop impedan...

To predict noise in enclosure containing treated vibrating panels, porous layer effect has to be taken into account. This study propose an analytical model of the effects of a porous layer on a vibrating plate by separating the acoustical and vibratory behaviours. This paper deals with acoustic coupling by means of surface impedance derived by a one-dimensional model using ”Biot-Allard” theory....

We propose a model-based control framework for multi-arm manipulation of a rigid object subject to external disturbances. The control framework, based on projected inverse dynamics, decomposes the control law into constrained and unconstrained subspaces. Unconstrained components accomplish the motion task with a desired 6-DOF Cartesian impedance behaviour against external disturbances. Meanwhil...

We are developing a novel interconnection method to form reliable joints between truly stretchable electrode mounts and rigid substrates. This is needed as the electrodes must be connected to implanted electronics if they are to be used for long term implantation, and the components are most often mounted on a rigid substrate and protected within a solid enclosure. In this paper we describe the...

Nominal rigidities have an important role in macro models used for the analysis of monetary policy. Recently, attractive prices (also known as price points) have often been referred to as one important potential explanation of nominal rigidities. An increased interest on attractive prices as an explanation for price rigidities rests on online pricing, in the context of which it has been shown t...
