Modern computer systems often incorporate multiple computational devices such as conventional processors, graphics processing units (GPUs), specialized accelerators, and field-programmable gate arrays (FPGAs). Programmers are able to exploit these new architectures for improved performance and reduced power consumption, but at the cost of increased programing complexity. Further complicating matte ...

Unmanned Air Vehicle (UAV) developers have limited marketplace options for motor speed controllers.The largest commercial controllers are generally limited to below 12 kW and battery voltages of less than 50 V, Although these are well suited to 800 Class helicopters and Giant scale fixed-wing aircraft, they are not powerful enough for larger UAV development.A few high-power options exist up to 25 ...

Plasmonic metamaterials, composed of patterned metallic and dielectrics, can be engineered to have interesting optical properties that are attractive for a range of advanced obscurant applications. These particles are typically fabricated on planar surfaces, since patterning planar surfaces to achieve the desired effects is relatively straightforward.However, for planar geometries the particles op ...

Techshot is pleased to provide this phase II proposal to continue our exciting scaffold development work in creating a Tissue Engineered Vascular Graft (TEVG).This off the shelf conduit will be capable of being combined with the patients own cells either at the time of surgery or by healing and remodeling in situ to provide a long term solution to revascularization due to traumatic injury.We inten ...

Cognitive skills/capabilities are important for the military personnel to fulfill tasksand to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. To take full advantage of such a brain stimulation t ...

ABSTRACT: We propose to build Infrared LED (IRLED) scene projectors that are able to project larger than 1k by 1k imagery with maximum temperatures of 3000K, frame rates in excess of 400 Hz, and emission wavelength between 3 and 5 microns. Our team consists of experienced IRLED fabrication experts, RIIC designers, and packaging specialists.; BENEFIT: Infrared LED (IRLED) arrays represent a potenti ...

Modulation linearity and efficiency, in addition to bandwidth, are important parameters characterizing a modulator. In general, improving modulation efficiency is highly desirable, as long as bandwidth is maintained, since higher modulation efficiency allows lower RF signal to impose equivalent change in the optical beam; better linearity of modulation reduces spurs and improves the fidelity of op ...

ABSTRACT: A challenge which continues to present a barrier to the utilization of AM and wide spread adoption is knowing when to use the technology. This is particularly problematic in aerospace and in MRO operations because the technology is still emerging, and knowledgeable, experienced practitioners remain in short supply and will likely remain so until the next generation of technicians and eng ...

A FEASIBILITY STUDY ON THE DEVELOPMENT OF A STOICHIOMETRIC DIESEL ENGINE IS PROPOSED USING THE THERMAL IGNITION COMBUSTION CHAMBER. THE ADIABATIC DIESEL ENGINE WITHOUT WATER OR AIR COOLING ALLOWS THE THERMAL IGNITION CHAMBER TO STORE HEAT DURING COMBUSTION AND RELEASE THE ENERGY FOR IGNITION IN THE FOLLOWING CYCLE. INJECTION OF FUEL ON TO 1800-2000 DEG. F WALL TEMPERATURE WILL PREPARE THE FUEL FOR ...

THIS PROPOSAL IS TO DEMONSTRATE FEASIBILITY OF INSERTION OF SIALIC ACID MOLECULES INTO MEMBRANES OF LIPOSOMES CARRYING HEMOGLOBIN. THE LIPOSOMES MAY BE PROVIDED BY NAVY CONTRACTORS OR PREPARED BY OFFEROR ACCORDING TO CONTRACTORS' SPECIFICATIONS FOR FOMULATION. THE ADDED SIALIC ACID WILL PROTECT THE LIPOSOMES FROM CLEARANCE BY THE RETICULOENDOTHELIAL SYSTEM AND THEREBY INCREASE THE RESIDENCY TIME O ...
