Mismatch-shaping digital-to-analog converters (DACs) have become widely used in high-performance delta–sigma data converters because they facilitate delta–sigma modulators with multibit quantization. Relative to single-bit quantization, multibit quantization significantly relaxes the analog circuit performance necessary to achieve a given level of data converter precision, but significant digit...

A new therapy planning strategy We are investigating a new therapy planning strategy: interactive dose shaping (IDS). This planning paradigm aims to perform interactive local dose adaptations of a plan without compromising already established valuable dose features in real time. The key operation that facilitates dose shaping in real time by a direct interaction with a 3D dose distribution thro...

By using a water transmission line, current wave shaping was demonstrated for a fast capillary Z-pinch discharge recombination soft x-ray laser study. The pulsed power system consists of a water capacitor, a gap switch, a transmission line, and a capillary plasma load. A voltage wave initiated at the water capacitor propagates toward the capillary load through the transmission line. Control of ...

Jacquier Polson and Rossi J Business and Economic Statistics have pro posed a hierarchical model and Markov Chain Monte Carlo methodology for parameter estima tion and smoothing in a stochastic volatility model where the logarithm of the conditional vari ance follows an autoregressive process In sampling experiments their estimators perform par ticularly well relative to a quasi maximum likelih...

Human activity recognition (HAR) using smartphone sensors utilize time-series, multivariate data to detect activities. Time-series data have inherent local dependency characteristics. Moreover, activities tend to be hierarchical and translation invariant in nature. Consequently, convolutional neural networks (convnet) exploit these characteristics, which make it appropriate in dealing with time...

Mobile communication system uses Quadrature Phase Shift Keying (QPSK) as one of the efficient digital modulation techniques. Pulse-shaping technique plays an important role in digital transmission. Root-Raised Cosine (RRC) and Raised Cosine (RC) filters are two important pulse-shaping filters used in mobile communication system. In this paper we have presented the study of some useful parameter...
