In this paper the tunable M-channel filters based on Thue-Morse heterostructures consisting of single -negative materials has been studied. The results showed that the number of resonance modes inside the zero- gap increases as the number of heterogenous interface, M, increases. The number of resonance modes inside the zero- gap is equal to that of heterogenous interface M, and it can be used a...

  Abstract   Explosive welding is a solid state process in which bond is produced by a high oblique impact of two plates with the controlled explosive charge. In this paper, the explosive welding of Ms90 brass flyer plate with the St14 steel base plate are considered by using the parallel set up geometry. From the practical viewpoint, various parameters such the stand-off distance, dynamic angl...

Introduction: User interfaces are a crucial factor in ensuring the success of mobile applications. Mobile Educational Applications not only provide flexibility in learning, but also allow learners to learn at any time and any place. The purpose of this article is to investigate the effective factors affecting the design of the user interface in mobile educational applications. Methods: Quantita...

  In this paper, the density of states (DOS) of a planar d-wave Josephson junction is studied analytically. Two high temperature superconductors are separated by an interface with finite transparency coefficient. The c-axes are parallel to the interface and ab-axes have a mis-orientation. The tunneling occurs via the interface because of phase difference between superconducting bulks. The effec...

In this research, Effect of explosive ratio parameter on interface properties of explosively bonded copper-410 martensitic stainless steel were investigated, plates were welded in constant standoff distance with different explosive ratios. Optical microscopy, scanning electron microscopy, Microhardness and Tensile shear tests were carried out. The results showed that wavelength, wave amplitude,...

 Background and aims: Interface analysis methods are used to assess the man-machine interface of a particular system, product or device. Interface analysis methods can be used to assess a number of different aspects associated with a particular interface, including usability and user satisfaction. The purpose of this study is to evaluate the usability level of gas chromatographs that are being ...
