Microbial molecular ecology approaches were used to the effects of Bar-transgenic rice on Intestinal Microflora of the Mice (Mus musculus). Kunming mice (Mus musculus) of 100 SPF-grade (20 ± 2 g), half of which were male and the other half female, were randomly divided into five groups with four replications per group and five mice per replication to assess the safety of Bar-transgenic rice. Fi...

We investigate the locomotion of a surface-walking/climbing robot, the Planar Walker, based on a novel planar eight-bar closed-loop mechanism. The robot can produce inchworm-like movements in two orthogonal directions and can rotate about itself. The locomotion mechanism to achieve such motions comprises four two-way linear cylinders forming a deformable quadrilateral and four two-way gripper m...

This article proposes a method to estimate the axial force in a bar based on local vibration measurements. The method assumes Timoshenko beam theory and in addition accounts for the rotational inertia of the bar and the mass of the sensors. A major advantage of the proposed method is its generality. Assuming at least five sensors along the length of the bar, no information on the connection of ...

This paper presents a method for estimating the position of a mobile robot in an indoor environment. The proposed technique uses a model of the environment formed by two panoramic cylindrical images taken at di erent locations, and a planar image taken at the current position. The current position and orientation of the robot are then computed without any additional information. We assume that ...

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...
