The compact representation of harmonic amplitudes in the sinusoidal coding of speech is an important problem in low bit rate speech compression. A widely used method to achieve this is by the all-pole modeling of the spectral envelope. Often a perceptually warped frequency scale is applied in the all-pole modeling to improve perceived accuracy at low model orders. In this work, an attempt is ma...

The present study investigates the crystal preferred orientation (CPO) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (EBSD) on quartz crystals from north of the Renvyle-Bofin Slide (RBS) nearLetterfrack in western Ireland. Complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...

Several methods are available for performance prediction of single phase shaded pole induction motors. A simple model, in conjunction with a more complicated and accurate model, which considers the asymmetrical windings and core loss, is used to compare the prediction methods against experimental results. Saturation is incorporated in the model. Fundamental and harmonic flux density wave distri...

Pairing of homologous chromosomes is a crucial step in meiosis, which in fission yeast depends on nuclear oscillations. However, how nuclear oscillations help pairing is unknown. Here, we show that homologous loci typically pair when the spindle pole body is at the cell pole and the nucleus is elongated, whereas they unpair when the spindle pole body is in the cell center and the nucleus is rou...

The paper analyzes global solutions to the optimal digital controller realization problem based on maximizing a finite word length (FWL) closed-loop stability measure. For each closed-loop eigenvalue, a single-pole FWL stability function is first introduced, and a single-pole FWL stability measure is then defined as the maximum of the corresponding single-pole stability function over all the co...

The pole vaulting is a sport with a long history involving complex dynamic motion. The aim of pole vaulting for the athlete is to achieve maximum height. The dynamic behavior of the pole-athlete system is identical to an inverted pendulum system with the buckling pole acting as a spring. The purpose of this paper is to study the influence of factors on the pole vaulting performance such as the ...

This paper proposes a dual-harmonic pole-changing (PC) motor with split permanent magnet (PM) poles (DHPCM-SPMPs). By adopting PM pole structure, the amplitude of third flux density is increased greatly. Therefore, when PC winding adopted to couple fundamental and components, respectively, proposed can work as satisfy operating demands electric tractors. The design effect structure introduced f...

In Stage 1 of 4 experiments in which rats completed a water-maze blocking procedure, experimental groups were trained to use a predictive beacon (hanging above, connected to, or displaced from the platform) to find a submerged escape platform in the presence of predictive or irrelevant background cues and in the presence or absence of irrelevant landmarks. In Stage 2, a fixed beacon, landmarks,...

The possibility and the implications of the idea, that pulsars are born as strange stars, are explored. Strange stars are very likely to have atmospheres with typical mass of ∼ 5 × 10M⊙ but bare polar caps almost throughout their lifetimes, if they are produced during supernova explosions. A direct consequence of the bare polar cap is that the binding energies of both positively and negatively ...
