Abstract: Working set ratio estimations of data items in a sliding time window are determined to dynamically allocate storage for the data items. A working set ratio may be determined by accessing a fixed-size array that stores respective timestamps of last accesses of data items to determine which data items are useful to determine an estimate of a working set for the application within a range of time. The working set ratio is then determined from an estimated working set and an amount of computing resources allocated to the application by the estimated working set. The amount of the computing resources allocated to the application may then be automatically scaled according to the determine working set ratio.

Abstract: A method of fabricating a plurality of seat elements is provided. The plurality of seat elements are styled to have a range of styling features. The method includes a step of determining the range of styling feature by selecting characteristics of a middle ply of foam and/or the exterior ply of the trim cover and selecting a number and position of panels that are sewn to form the trim cover. The seat elements are fabricated on a common mold apparatus.

Abstract: The microwave absorption performance of a fiber loaded thermoplastic syntactic material is improved by geometrically reshaping the surface into a waffle shape. Starting with a fiber loaded version of thermoplastic syntactic foam, the front face geometry is then modified. Typically, the angle and frequency response is a function of both the front face angle and the skin thickness. These effects are minimized in this concept by using a pyramidal surface in which the field enters the material normal to at least one surface at almost all incident angles. The attenuation is over 20 dB, from S through Ku bands, over a broad angle range of up to 75 degrees off normal. An added benefit is that this system has a rigidity that is suitable for many structural applications.

Abstract: A body containing lengths of fiber embedded therein is formed by providing a winding fixture including a plurality of parallel support rods spaced apart in a Z-direction. A length of a fiber is wound over the rods such that a portion of the fiber extends in the Z-direction, to form a skeletal structure. The fiber may be coated, as with a resistive material to modify energy absorbtion, after winding. The skeletal structure is filled with foam, and the support structure is removed to leave a structure in which discrete lengths of fiber embedded in the foam lie parallel to the Z-direction. The fibers may be transferred to a sheet of uncured polymeric material by placing the foam piece in contact with the sheet of polymeric material and forcing the fibers into the sheet under an applied pressure.
