In this paper we study the departure processes of two rate-control throttles: the token bank and the leaky bucket. Using sample path methods and the notion of majorization, we analyze the eeect that parameters such as the token buuer capacity and token generation period have on the vector of interdeparture times. In the transient case, we establish the monotonicity of the burst reduction in the...

BACKGROUND Heart failure (HF) is a syndrome that leads to poor outcome in advanced forms. The neurohormonal blockade modifies this natural history; however, it is often suboptimal. OBJECTIVE The aim of this study is to assess at what percentage cardiologists used to treating HF can prescribe target doses of drugs of proven efficacy. METHODS A total of 104 outpatients with systolic dysfuncti...

Reduction of a large system of equations to a lower-dimensional system of similar dynamics is investigated. For dynamical systems with disparate timescales, a criterion for determining redundant dimensions and a general reduction method based on the minimization of evolution rate are proposed.

This paper analytically studies performance improvement with traffic dispersion for QoS guaranteed applications. In the analysis, we suppose that connection admission control based on the effective bandwidth is performed in packet network. Numerical results exhibit that traffic dispersion can greatly reduce the total effective bandwidth required by a source and the blocking rate of sources.

In this paper, we study dimension reduction of the three-dimensional (3D) Gross–Pitaevskii equation (GPE) modeling Bose–Einstein condensation under different limiting interaction and trapping frequency parameter regimes. Convergence rates for the dimension reduction of 3D ground state and dynamics of the GPE in the case of disk-shaped condensation and cigar-shaped condensation are reported base...

--In OFDM systems, Fast Fourier transform (FFT) is used for frequency translation, and recently Discrete Wavelet Transform (DWT) has replaced FFT for frequency translation. 16-QAM (Quadrature amplitude modulation) scheme has been used in the OFDM system for both DWT and FFT based models. This work presents a modified OFDM system that is based on a low complexity interleaving process which is ap...

The compression of digital video data has many applications in the transmission and storage of video sequences. For moderate compression ratios there are many techniques which can provide satisfactory performance, for high compression ratios, however, typical compression techniques produce noticeable artifacts in the reconstructed video. This paper proposes a technique for the post-processing o...

Methemoglobin is not present in spectroscopically detectable amounts’ in freshly drawn blood of normal animals of the following and, presumably, other mammalian species: human, dog, cat, rabbit, rat, mouse, horse, monkey (Macacus rhesus), cattle, swine. Furthermore, methemoglobin is not demonstrable in incubated sterile blood from normal animals of these species for many hours after removal fro...

This study compares canonical and phonetic articulation rates of European Spanish and Portuguese based on radio podcasts. The main goal of the investigation is to establish the degree of syllable deletion based on vowel/consonant elision in both languages. The results show that Portuguese and Spanish speakers exhibit no difference in canonical articulation rate but Portuguese speakers reduce sy...
