This paper describes a combined Adaptive Transform Codec (ATC) and Code-Excited Linear Prediction (CELP) algorithm, called ATCELP, for the compression of wideband (7 kHz) signals. The CELP algorithm applies mainly to speech, whereas the ATC mode is selected for music and noise signals. We propose a switching scheme between CELP and ATC mode and describe a frame erasure concealment technique. Su...

The decision regarding the best suitable microprocessor for a given task is one of the most challenging assignments a hardware designer has to face. In this paper, we make a comparison of cycle-accurate VHDL clones of the 8-bit Atmel ATmega, the 16-bit Texas Instruments MSP430, and the 32-bit ARM Cortex-M0+. We investigate their runtime, chip area, power, and energy characteristics regarding El...

The binary counter is a fundamental unit of computer operation. The goal of this project is to lower the supply voltage and find the optimal supply voltage which provided less power

Ab initio potential energy and dipole moment surfaces are computed for sulfur trioxide (SO3) at the CCSD(T)-F12b level of theory with appropriate triple-zeta basis sets. The analytical representations of these surfaces are used, with a slight correction, to compute pure rotational and rotation-vibration spectra of (32)S(16)O3 using the variational nuclear motion program TROVE. The calculations ...

16/32-Gbit NAND-Flash memories have been tested under heavy ion irradiation. The cross section and the current waveforms for Destructive Failures and the annealing of hard and soft SEUs are presented.

Time- and frequency-domain measures of discharge times for pairs of motor units are used to infer the proportion of common synaptic input received by motor neurons. The physiological mechanisms that can produce the experimentally observed peaks in the cross-correlation histogram and the coherence spectrum are uncertain. The present study used a computational model to impose synchronization on t...
