Abstract: A method for performing opportunistic write-back discard of single-use vector register values. The method includes executing instructions of a GPU in a default mode, detecting a beginning of a single-use section that includes instructions that produce single-use vector register values, and executing instructions in a single-use mode. The method includes discarding the write-back of a single-use vector register value if the single-use value gets forwarded either via a bypass path or via register file cache. The method includes inserting hint instructions into an executable program code that demarcates single-use sections. A system includes a microprocessor to execute instructions in the default mode. The microprocessor detects a beginning and an ending of a single-use section that includes instructions that produce single-use vector register values.

Abstract: A method of calculating blast injury metrics in a weapon training/IED blast scene can include: reconstructing topological layout of the scene having at least one real subject and a blast source; obtaining anthropometric and posture data for each real subject; obtaining anatomical soldier model for each real subject; identifying real position of at least one real pressure sensor on each soldier during a blast; positioning a virtual sensor on each anatomical soldier model to correspond with real pressure sensor on the real subject; calculating weapon signature of the blast source, the weapon signature including pressure versus time for a blast from the blast source; generating simulated pressure traces on each anatomical soldier model at east virtual pressure sensor; calculating blast injury metrics for the at least one real subject; and generating a report that includes the blast injury metrics for the at least one real subject.

Abstract: The self-erecting structure has resilient lower and upper support loops which provide it with shape and support. Fabric covers the support loops, and is permanently affixed to the support loops. The fabric has a lower, waterproof portion and an upper insect protection portion. The fabric is preferably treated to provide it with insect repellent and insecticide properties. The support loops are made of flexible, resilient rods made of a material, such as a vinylester and fiberglass combination having a diameter selected to enable the support loops to be folded into six loops, whereby the structure can be compactly stored in a rucksack. The method of folding the structure so that it can be stored in such a compact space is also disclosed.
