Due to their high kinematic characteristics, six-bar tensegrities have great potential application value in the field of robotics, especially deep space exploration robots. In this paper, an ultralight tensegrity robot is designed, and a gait planning method for continuous motion proposed. First, equilibrium matrix structure constructed, singular decomposition (SVD) performed find node coordina...

abstract soil moisture measurement and control is a base to employ optimal management methods for reducing water consumption and improvement of the product quality. the main objective of this research was increasing the efficiency of water consumption in a greenhouse condition. this study was carried out in the framework of three treatments of soil potential including irrigation at 40, 60 and 8...

Two aspects of handwashing in hospital were considered. A study was carried out to examine the contamination of bar soap and containers, and the use of antiseptic soaps in reducing the resident flora of the skin. Swabs were collected from soap dishes on six wards and from a bacteriology laboratory on four consecutive days. The unmedicated bar soap was replaced by bar soap containing 2.5% povido...

This paper presents the results of a recent project of IKCo’s research center to modify Paykan 1600’s rear suspension mechanism with the purpose of improving comfort, stability and handling qualities. The car was originally equipped with a solid rear axle with leaf springs. By replacing the original mechanism with a three-link mechanism with panhard bar and coil springs, the ride comfort and ha...

Neurons transmit information to distant brain regions via long-range axonal projections. In the mouse, area-to-area connections have only been systematically mapped using bulk labeling techniques, which obscure the diverse projections of intermingled single neurons. Here we describe MAPseq (Multiplexed Analysis of Projections by Sequencing), a technique that can map the projections of thousands...

In this paper, we are concerned with a discrete tomography problem. We seek to reconstruct a binary image from its orthogonal projections, i.e, its horizontal and vertical line sums without interior black holes. We provide a tabu search approach to minimize the number of holes while satisfying the projections. We test our approach on some random binary images. Computational results show that th...

Recently, a new type of mechanism called compliant mechanism has been developed and applied mainly in the field of micro-mechanics. A compliant mechanism has flexible parts to stabilize the structure, which is contrary to the conventional unstable mechanism. Although a compliant mechanism is usually modeled as a continuum with elastic joints, it is possible to generate the similar mechanism by ...
