background brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus brucella. the cgt gene (cyclic β-1, 2 glucan transporter gene) is a virulent factor in brucella genus. the present study was conducted with the aim of cloning and expression of brucella cgt gene. materials and methods brucella melitensis cgt gene was amplified from extracted chromoso...

This paper presents two techniques to detect and classify navigable terrain in complex 3D environments. The first method is a low level on-line mechanism aimed at detecting obstacles and holes at a fast frame rate using a time-of-flight camera as the main sensor. The second technique is a high-level off-line classification mechanism that learns traversable regions from larger 3D point clouds ac...

Robust detection of moving objects from a mobile robot is required for safe outdoor navigation, but is not easily achievable since there are two motions involved: the motions of moving objects and the motion of the sensors used to detect the objects. We have experimented with a probabilistic approach for moving object detection from a mobile robot using a single camera in outdoor environments. ...

Tracking in essence consists of using sensory information combined with a motion model to estimate the position of a moving object. Tracking efficiency completely depends on the accuracy of the motion model and of the sensory information. For a vision sensor like a camera, the estimation is translated into a command to guide the camera where to look. In this paper, we contribute a method to ach...

This paper proposes a method of robust optimal stabilization for balance systems such as rocket and missile systems, Segway human transportation systems, and inverted pendulum systems. Constant-gain controllers such as linear-quadratic regulators may not guarantee stability let alone optimality for balance systems affected by parametric variations. The robust stability and robust performance ac...

This paper presents the development of a simulation test bed for a command, control, computer, communication, intelligence, surveillance and reconnaissance (CISR) system. The test bed features coordination of a rotorcraft unmanned aerial vehicle (RUAV) and multiple unmanned ground vehicles (UGVs) by integrating a high-fidelity rotorcraft model with actual ground-based robots that emulate UGVs. ...

The essential dynamics algorithm is a novel policy search algorithm for learning in a class of stochastic Markov decision processes (MDPs) with continuous state and action spaces. We apply it to the control of a 5 degree of freedom robot arm atop a Segway base. Movement of the arm causes the base to translate and tilt, which in turn affects the movement of the arm. The state space has 14 dimens...

1930 www.thelancet.com Vol 372 December 6, 2008 or febuxostat). Enhanced understanding of pathophysiological mechanisms might lead to improved drugs, with reduced potential for side-eff ects compared with today’s uricosurics. Even more exciting is the idea that responding to the defects of these transporter proteins might have further benefi cial eff ects, because they could also transport othe...

objective: recent studies suggest that intermittent and prolonged normobaric hyperoxia (ho) results in ischemic tolerance to preventing ischemia brain injury. in this research attempts were made to see the changes in excitatory amio-acid transporter 3 (eaat3), tnf-α levels, and nf-κb activity following prolonged and intermittent nbho preconditioning. materials and methods: rats were divided i...
