One Nodal Thermal Analysis for Nano and Micro Satellites on Sun-Synchronous and Circular Orbits

response articles: micro and macro analysis

the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...

Frequency Analysis of Embedded Orthotropic Circular and Elliptical Micro/Nano-Plates Using Nonlocal Variational Principle

In this paper, a continuum model based on the nonlocal elasticity theory is developed for vibration analysis of embedded orthotropic circular and elliptical micro/nano-plates. The nano-plate is bounded by a Pasternak foundation. Governing vibration equation of the nonlocal nano-plate is derived using Nonlocal Classical Plate Theory (NCPT). The weighted residual statement and the Galerkin method...

A Simple Low Cost Digital Sun Sensor for Micro-satellites

A Digital Sun Sensor (DSS) has several advantages if compared to the analogue one. It achieves higher accuracy and avoids the problems with light being reflected from the Earth’s surface. The gradual degradation of the sensitivity of the elements due to radiation effects is not crucial for its proper functioning. The advances in CCD and recently in CMOS technology make possible to implement the...

MEMS Technology for Optical Crosslink for Micro/Nano Satellites

We report on a novel, compact twodimensional (2D) scanning micromirror for free space optical crosslinks for micro and nano satellites. Using a novel micromachined structure called MicroElevator by Self-Assembly (MESA) [1], the micromirror is suspended above the substrate by several hundred micrometers. Large mirror size and wide scanning range are achieved simultaneously. Large number of resol...
