At the heart of scientific computing and numerical analysis are linear algebra solvers. In scientific computing, the focus is on the partial differential equations (PDEs) that arise from computational fluid dynamics (CFD), climate modeling, astrophysics, and structural and heat analysis that cannot be solved analytically. Certain problem formulations lead to sparse matrices, in which the majority ...

In this SBIR project, AlphaSense, Inc. and the Carnegie Mellon University propose to develop a RF receiver front end based on CMOS-MEMS components for miniaturized digital EVA radio applications. In Phase I, we have proven the feasibility of implementing a compact, low power and high performance S band receiver front end based on CMOS- MEMS components. Specifically, we conducted link budget analys ...

Advanced reconfigurable/reprogrammable communication systems will require use of commercial sub 100 nm electronics. Legacy radiation tolerant circuits fail to provide Single Event Upset (SEU) immunity at speeds greater than 500 MHz. New base level logic circuits are needed to provide SEU immunity for high speed circuits afforded by sub 100 nm technology. A completely new circuit and system appr ...

In an attempt to build more computationally powerful systems and improve the FLOPS/dollar and FLOPS/Watt of high-performance computers (HPCs), we have recently seen the proliferation of GPU-based clusters. Many major vendors are now supporting this technology and such systems are becoming increasingly common everywhere from university research labs to the Top500 supercomputer list. To take advan ...

In this proposal, AlphaSense, Inc. and the University of Washington detail the development of a novel, high performance Ka band power amplifier for EVA radio applications. Key innovations of our approach include: a) The application of a class-E power amplifier to ensure high power efficiency, b) The EER power amplifier topology to enhance the linearity performance of the class-E amplifier, and c) ...

Space-based imaging sensors are important for NASA's mission in both performing scientific measurements and producing literature and documentary cinema. The recent proliferation of high-definition capture devices and displays (HDTV) provide the general public with first-hand human experiences hundreds miles above sea level in brilliant detail. The recent IMAX film "Hubble," which features one ...
