Tripulse is a novel orientation/attitude estimation system that is designed to accurately estimate the orientation of a satellite borne phased array relative to one or more earth stations. This system has an accuracy potential that is signi cantly better than conventional Earth-Moon-Sun attitude sensors. Tripulse has conceptual similarities to amplitude comparison monopulse systems used in trac...

objective the hippocampal circuit integrity is crucial for learning and memory. despite the existing reports on hippocampal–dependent memory impairment due to noise stress, there are only a few studies on the effect of noise stress on anatomical structure of hippocampus. the present study is aimed to investigate the likely effects of chronic noise exposure on the volume of rat hippocampus. mate...

We report on microwave measurements of superconducting aluminum hot-electron bolometers (Al HEBs). Diffusion-cooled Al HEB mixers are ideal candidates for space-borne and terrestrial remote-sensing applications in the Terahertz frequency range since they are predicted to have small local oscillator (LO) power requirements, intermediate frequency (IF) bandwidths ! 10 GHz, and a noise temperature...

The map-making step of Cosmic Microwave Background data analysis involves linear inversion problems which cannot be performed by a brute force approach for the large timelines of today. We present in this article optimal vector-only map-making methods, which are an iterative COBE method, a Wiener direct filter and a Wiener iterative method. We apply these methods on diverse simulated data, and ...

We demonstrate theoretically and experimentally the reconstruction of images borne on incoherent light at a resolution greatly exceeding the finest resolution defined by the NA of the system. Our method relies on compressed sensing techniques, which assume that the object is sparse in a known basis, and only that. The approach is robust against noise and can be used for reconstructing subwavele...
