Attribute-specific mode choice models predict the distribution of traffic among the various modes available, on the basis of some attributes. We consider the effect on valuation of one important attribute of mode choice, namely the travel time, for a population of commuters, when wireless internet access (wi-fi) is provided on trains. We use activity demand models to derive certain parameters o...

The Morse-Smale complex is an important tool for global topological analysis in various problems in computational topology and data analysis. A certified algorithm for computing the Morse-Smale complexes has been presented for two-dimensional Morse-Smale systems in bounded planar domains [3]. In the current article we extend the approach in case of MorseSmale systems on two-dimensional manifold...

In dentistry, many preparation guidelines for allceramic crowns are still based upon clinical experience and those developed for metal ceramic crowns that may not be applicable and need further experimental and numerical evaluation. Some specific features are requiring investigation in dental prosthetic devices, for example, configurations of the crowns’ margin [1], marginal thickness [2, 3] an...

A hybrid estimator of the log-spectral density of a stationary time series is proposed. First, a multiple taper estimate is performed, followed by kernel smoothing the log-multiple taper estimate. This procedure reduces the expected mean square error by (π 2 4) 4/5 over simply smoothing the log tapered periodogram. A data adaptive implementation of a variable bandwidth kernel smoother is given.

BACKGROUND: This study examined muscle deoxygenation trends before and after a 7-day taper using non-invasive near infrared spectroscopy (NIRS). METHODS: Eleven cyclists performed an incremental cycle ergometer test to determine maximal oxygen consumption (VO2max = 4.68 +/- 0.57 L.min-1) prior to the study, and then completed two or three high intensity (85-90% VO2max) taper protocols after bei...

In this paper we study the performance of the low-variance multi-taper Mel-frequency cepstral coefficient (MFCC) and perceptual linear prediction (PLP) features in a state-ofthe-art i-vector speaker verification system. The MFCC and PLP features are usually computed from a Hamming-windowed periodogram spectrum estimate. Such a singletapered spectrum estimate has large variance, which can be red...

Twenty eight patients treated with selective serotonin reuptake inhibitors /venlafaxine were randomized to a three-day (short) or 14-day (longer) anti-depressant taper and openly assessed after a five to seven day drug-free washout, and again after seven days treatment with a new anti-depressant of the treating clinician's choice. A 'discontinuation syndrome' ( > or = 3 new symptoms on the Disc...

Objective The purpose of this study was to measure the temperature of the plugger tip of 3 cordless heat carriers set at 200°C. Materials and Methods Pluggers of the same taper (0.06, 0.08, 0.10) and similar tip sizes (sizes of 50 and 55) from 3 cordless heat carriers, namely SuperEndo-α2 (B & L Biotech), Friendo (DXM), and Dia-Pen (Diadent), were used and an electric heat carrier, System B (...
