fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). it is well known that the structure and prope...

In order to study how the geometric parameters and shape of the micro-structure surface of a bionic heart valve affects hemocompatibility, mastoid micro-structures with different periodic space were fabricated using a femtosecond laser on a polyurethane (PU) surface. The apparent contact angles of droplets on the micro-structure surfaces were measured to characterize their wettability. Then a s...

A new planar structure of solid propellant micro -rocket for micro-spacecraft and Micro-Air-Vehicle applications is reported in this paper. We have successfully fabricated an array of micro-rockets using MEMS technology. For a lowpower consumption, the micro-igniter used here is a resistor deposited on a low tensile stress thin membrane to ensure a good heat transfer to the propellant. Experime...

with success of islamic revolution of iran in 1979, the category of religious belifes and values converted to one of the most important and constitutive principles in iran s foreign policy that reflected in decision-making sphere. this article with concerning islamic identity as a revival fragment in central asia and it,s inability to play constructive role in iran,s national interest securing,...

This paper is an investigation of the organization of a parallel micro-computer designed to emulate a wide variety of sequential and parallel computers. This micro-computer allows tailoring of its control structure so that it is appropriate for the particular computer to be emulated. The control structure of this micro-computer is dynamically modified by changing the organization of its data st...

In this paper the dynamic analysis of a macro–micro parallel manipulator is studied in detail. The manipulator architecture is a simplified planar version adopted from the structure of the Large Adaptive Reflector (LAR), the Canadian design of next-generation giant radio telescopes. In this structure it is proposed to use two parallel redundant manipulators at the macro and micro level, both ac...
