A method is presented for enhancing the narrowband interference rejection capability of direct-sequence spread-spectrum systems employing an adaptive notch filter. The method, based on projection onto convex sets, restores that part of the spread-spectrum signal distorted by the filter. Simulation results are presented which show the output bit-error rate (BER) improvement gained by using the s...

BACKGROUND The Multicenter Automatic Defibrillator Implantation Trial (MADIT)-II demonstrated that implantable cardioverter defibrillators (ICDs) save lives when used in patients with a history of myocardial infarction (MI) and an ejection fraction of 0.3 or less. OBJECTIVE To investigate the cost-effectiveness of implanting ICDs in patients who met MADIT-II eligibility criteria and were enro...

Dependency parsing has gained attention in natural language understanding because the representation of dependency tree is simple, compact and direct such that robust partial understanding and task portability can be achieved more easily. However, many dependency parsers make hard decisions with local information while selecting among the next parse states. As a consequence, though the obtained...

Diffraction gratings have been proposed as core elements in future laserinterferometric gravitational-wave detectors. In this paper, we use a steady-state technique to derive coupling of lateral grating displacement to the output ports of a diffractive Fabry-Perot cavity. By introducing a signal to noise ratio (SNR) for each of the three cavity output ports the magnitude of the noise sidebands ...

We demonstrate an all-optical transistor with the modulated output signal simultaneously having an output/input ratio > 3 dB and ON/OFF ratio > 20 dB. The microring based device is ultra-compact and CMOS compatible.

Voice of the customer (VOC) is a critical analysis procedure that provides precise information regarding customer input requirements for a product/service output. The ability to conduct a voice of the customer analysis, which could be gained through direct and indirect questioning, will enable engineers and other decision makers to successfully understand customer needs, wants, perceptions, and...

We discuss two packages in preparation, which calculate all possible two-body decays at full one-loop level of all scalars particles of the Minimal Supersymmetric extension of the Standard Model. The package HFOLD (Higgs Full One-Loop Decays) calculates the decay widths and branching ratios of the three neutral and charged Higgs bosons. The package SFOLD (Sfermion Full One-Loop Decays) computes...

This paper presents an improved affine projection algorithm based crosstalk resistant adaptive noise canceller (CRANC). The proposed CRANC consists of three adaptive filters, one of which is used for detecting speech activity and the others are employed to estimate the interference and crosstalk transfer functions, respectively. An efficient sequential speech detector is also proposed in this p...

All electronic processing components in future deep nanotechnologies will exhibit high noise level and/or low S/N ratios because of the extreme voltage reduction and the nearly erratic nature of such devices. Systems implemented with these devices would exhibit a high probability to fail, causing an unacceptably reduced reliability. In this paper we introduce an innovative input and output data...
