MAGNETORHEOLOGICAL FLUID DAMPER
1.INTRODUCTION
Vibration isolators or dampers are commonly used to mitigate vibrations in structures or machines. The isolators are typically passive and they are designed to reduce the vibration of the most undesired frequency. However, in many applications, the excitation frequency varies across a large range. In a semi-active device, the stiffness or damping can be adjusted during operation. Changing the stiffness of the support device can be exploited by moving the eigenfrequency o ....etc

With future threats emerging and the overall needs of the military changing, the armor mechanics community is always exploiting new materials and technologies to stay at the forefront of defense capabilities. Along these lines, this presentation will cover some of the research conducted at the Army Research Laboratory (ARL) and will be given in two parts. The first part will cover recent work completed on the ballistic testing of two silicon carbides with varying porosity distributions. The second part will go over a brief introduction of the w ....etc

ABSTRACT
Magneto rheological fluids commonly known as MR fluids are suspensions of solid in liquid whose properties changes drastically when exposed to magnetic field. Magnetorheological (MR) fluids are materials that respond to an applied field with a dramatic change in their rheological behavior. The essential characteristic of these fluids is their ability to reversibly change from a free-flowing, linear, viscous liquid to a semi-solid with controllable yield strength in milliseconds when exposed to a magnetic field. ....etc

ABSTRACT
A novel approach for estimating articulated body posture and motion from monocular video sequences is pro-posed. Human pose is defined as the instantaneous two dimensional configuration (i.e., the projection onto the image plane) of a single articulated body in terms of the position of a predetermined set of joints. First, statistical segmentation of the human bodies from the background is performed and low-level visual features are found given the segmented body shape. The goal is to be able to map these, g ....etc
