The braincap, as described in 3001: The Final Odyssey, the concluding edition of Arthur C. Clarke’s science ction classic, is the ultimate humancomputer interface: it connects the brain to a system that is able to read thoughts and upload new information. The wearer can in minutes acquire new skills that would otherwise take years to master. Currently, however, a system that uploads informati...
Introduction: Database design by taking into account the components of user interface, usability and technical issues, is a key indicator of quick access to the required information of the users. Ovid assessment criterion evaluates databases in terms of user interface, usability and technical issues. The purpose of the present paper is to determine the important elements in the design of user i...
In this paper, the microstructure and mechanical properties of the plain carbon steel-bronze interface of explosive welding and rolling were investigated. Explosive connection was done at two stop distances and with two different thicknesses of explosive material. Rolling of the welded composite was done at both ambient and preheated temperatures of 300 °C and with a constant thickness reductio...
An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...
بررسی تاثیر فاصله توقف جوشکاری انفجاری بر ساختار و رفتار خوردگی اتصال آلومینیوم 5083- مس در محیط نمک
In the present study, the effect of explosive welding stand-off distance on the structure and corrosion behavior of aluminum alloy 5083-copper joint is studied. The microstructure was examined by optical microscopy and scanning electron microscopy and corrosion behavior with poteniodynamic polarization tests and electrochemical impedance spectroscopy in a salt environment. Microscopic results s...
In the current research, the microstructural changes and corrosion behavior of two-layer Steel/Bronze sheets were investigated after the heat treatment of the explosive welding process. The heat treatment was performed at 600ºC for 16 hr. Dynamic potential polarization, electrochemical impedance spectroscopy, optical microscopy, and scanning electron microscopy analyses were used. Based on of t...
Introduction: In brachytherapy, radioactive sources are placed close to the tumor, therefore, small changes in their positions can cause large changes in the dose distribution. This emphasizes the need for computerized treatment planning. The usual method for treatment planning of cervix brachytherapy uses conventional radiographs in the Manchester system. Nowadays, because of their advantages ...
The existing theory for wave propagation through a soil layer are not compatible with the real soil layers because in the theory the layers are flat and the sub-layers are parallel, while in real the soil layers are not flat and they may not be parallel. Thus, wave propagations through a corrugated interface are so important. In this paper, a two-dimensional SH-wave propagation through a corrug...
