A large-angle beamstrahlung detector at CESR appears feasible[1] except for the unknown synchrotron radiation (SR) emitted at large (γθ >> 1) angle by the beam line magnets, most notably the quadrupoles adjacent to the CLEO IR. The purpose of this note is to describe a simple algorithm to extend the validity of the classical SR approach to angles far exceeding the typical angle θ = 1/γ. The bea...

In this paper, a model based sensor fusion algorithm for sensor networks is presented. The algorithm, referred to as distributed Kalman filtering is based on a previously presented algorithm with the same name. The weight selection process has been improved yielding performance improvements of several times for the examples studied. Also, solutions to both optimization problems involved in the ...

This paper presents an iterative CKY parsing algorithm for probabilistic contextfree grammars (PCFG). This algorithm enables us to prune unnecessary edges produced during parsing, which results in more efficient parsing. Since pruning is done by using the edge’s inside Viterbi probability and the upper-bound of the outside Viterbi probability, this algorithm guarantees to output the exact Viter...

In this article, we propose a space–time adaptive processing scheme via a generalized sidelobe canceler (GSC) architecture for airborne multiple-input multiple-output (MIMO) radar. This scheme employs the waveforms extracted by the matched filter bank that is cascaded at the receive end and utilizes digital beamforming technique to synthesize a certain number of transmit–receive beams, therefor...

We consider topology based criteria for the selection of optimal beam orientations for conformal external radiotherapy. The advantage of such an approach is that computation time is considerably reduced since no dose calculation is required. The algorithm preclassifies all possible irradiation directions by assigning to each a fitness measure, the geometry fitness factor (GFF). This factor is a...

In this paper we experimentally analyze the performance of a twisted nematic liquid crystal on silicon (LCoS) display as a function of the angle of incidence of the incoming beam. These are reflective displays that can be configured to produce amplitude or phase modulation by properly aligning external polarization elements. But we demonstrate that the incident angle plays an important role in ...

We propose an intuitive, simple and hardware friendly, yet surprisingly novel and efficient, received signal’s angle of arrival (AoA) estimation scheme. Our intuitive, twophases cross-correlation based scheme relies on a switched beam antenna array, which is used to collect an omni-directional signal using few elements of the antenna array in the first phase. In the second phase, the scheme swi...

An iterative beam shaping algorithm is proposed to simultaneously shape the amplitude and phase of an optical beam. The proposed algorithm consists of one input plane and two completely overlapped output planes which refer to the output plane in real space. The two output planes are imposed with both amplitude and phase constraints, and the constrained areas in the two output planes are complem...
