A dual-transducer system was used to test concepts for on-line guidance and lesion monitoring during ultrasound therapy. The system used a spherical-cap therapy transducer (4 MHz; 40-mm dia.; 90-mm focus) with a central, collinear transducer (7.5 MHz; 10-mm dia.) for A-mode examination. A digital system provided 3 operational modes, tested in in-vitro liver. Mode 1 senses in-situ therapy-beam h...
متن کاملSuperconducting Tes Bolometers above 1k
The discovery of High Tc superconductivity led to the exploration of current-biased superconducting bolometers cooled with liquid nitrogen and optimized to view 300K backgrounds at wavelengths beyond 10 μm. If such detectors reach the thermal fluctuation noise limit they would be a great improvement over room temperature pyroelectric detectors and thermopiles for many applications. The supercon...
متن کاملA computational approach for solving y2 =1k + 2k + ... + xk
We present a computational approach for finding all integral solutions of the equation y2 = 1k + 2k + · · ·+xk for even values of k. By reducing this problem to that of finding integral solutions of a certain class of quartic equations closely related to the Pell equations, we are able to apply the powerful computational machinery related to quadratic number fields. Using our approach, we deter...
متن کاملScheduling Direct Acyclic Graphs on Massively Parallel 1K-core Processors
The era of manycore computing will bring new fundamental challenges that the techniques designed for single core processors will have to be dramatically changed to support the coming wave of extreme-scale computing with thousands of cores on a single processor. Today’s programming languages (e.g. C/C++, Java) are unlikely to scale to manycore levels. One approach to address such concurrency pro...
متن کاملSIMinG-1k: A Thousand-Core Simulator running on GPGPUs
This paper introduces SIMinG-1k a manycore simulator infrastructure. SIMinG-1k is a GPU accelerated, parallel simulator for design-space exploration of large-scale manycore systems. It features an optimal tradeoff between modeling accuracy and simulation speed. Its main objectives are high performance, flexibility and ability to simulate thousands of cores. SIMinG-1k can model different archite...
