This study presents the effect of porosity on mechanical behaviors of a power distribution functionally graded beam. The Euler-Bernoulli beam is assumed to describe the kinematic relations and constitutive equations. Because of technical problems, particle size shapes and micro-voids are created during the fabrication which should be taken into consideration. Two porosity models are proposed. T...
In this paper, a fluidic biosensor with possibility to fabricate by Micro-Electro-Mechanical Systems (MEMS) technology is proposed for biomedical mass detection and lab-on-chip applications. This is designed by electromechanical coupling of harmonic micromechanical resonators with harmonic springers as a mechanical resonator array. It can disperse mechanical wave along the array by electrostati...
This paper describes the experimental design, implementation, and testing of a network for tele-command, control, and communications of micro robots over long distances. The system utilizes commercial low bandwidth satellites to transmit near real-time video and leverages micro-robot platform synergies for commandcommunications relays. The system is capable of controlling micro ground vehicles ...
شاخص سطح برگ استخراج‌شده (LAI) از تصاویر سنجش دور پارامتر مهمی، به‌منظور مدل‌سازی مکانی تولید پوشش گیاهی، محسوب می‌شود. معمولاً شاخص‌های گیاهی که با بازتاب طول موج‌های قرمز و مادون نزدیک محاسبه می‌شوند، در برآورد LAI استفاده روش‌های آماری، به‌کار می‌روند اما بسیاری این شاخص‌ها مقادیر متفاوت به اشباع می‌رسند. برای رفع محدودیت، محدودة لبة شده است؛ بنابراین، باید قابلیت داده‌های دور، ذرت علوفه‌ای، ...
A method of generating and measuring static small forces at the micro-Newton level is proposed. In the method, the down-slope component of gravity acting on a mass on an inclined plane is used as a static force. To realize a linear motion of the mass with a small friction, an aerostatic linear bearing is used. The forces acting on the mass, such as the down-slope component of gravity and the dy...
A rocking mass gyroscope (RMG) is a kind of vibrating mass gyroscope with high sensitivity, whose driving mode and sensing mode are completely uniform. MEMS RMG devices are a research hotspot now because they have the potential to be used in space applications. Support loss is the dominant energy loss mechanism influencing their high sensitivity. An accurate analytical model of support loss for...
Rural architecture of Iran in terms of functional nature and response to human needs, forms a homogeneous complex with a special physical identity whose identity derives from the concept of living and living in the village. With the advent of technology in rural life and changes in social and economic structure, the pattern of rural housing architecture has changed and evolved and today most ru...
Family, the basic unit of society, all over the world has been undergoing many fundamental changes and profound transformation due to comprehensive socio-economic development and technological advancement. This paper is a humble attempt to examine the factors affecting changes in family pattern, age at marriage, practice of dowry and divorce in family life of Bangladesh. The major factors affec...
OBJECTIVES To study the effect of different types of sports on plasma lipid profile. Subjects and method. Fasting plasma levels of total, LDL- and HDL-cholesterol (TC, LDLc, HDLc), triglycerides, phospholipids, apo A-I, apo B-100, and Lp(a) were measured in 28 swimmers, 17 volleyball players and 23 soccer players, and in a control group. All subjects participated in official national competitio...
