As part of his recent research into Cubical Spheres, G. Hetyei gave an inductive proof that a certain sequence of polynomials have nonnegative coe cients. In a poster session at the FPSAC'96 conference he asked for a combinatorial interpretation of these coe cients. In this short note we show that known results in rook theory imply that the coe cients count permutations subject to certain const...

Large sample properties are studied for a …rst-order autoregression (AR(1)) with a root greater than unity. It is shown that, contrary to the AR coe¢ cient, the leastsquares (LS) estimator of the intercept and its t-statistic are asymptotically normal without requiring the Gaussian error distribution, and hence an invariance principle applies. While the invariance principle does not apply to th...

Eigen-MLLR coe cients are proposed as new feature parameters for speaker-identi cation in this paper. By performing principle component analysis on MLLR parameters among training speakers, the eigen-MLLR coe cients (EMCs) are derived as the coe cients for the eigenvectors. The discriminating function of the new EMC features based on the Fisher criterion is found to be ten times larger than that...

This paper proposes a voice decomposition method based on voice model. Using correlation distance as a criterion frequency domain decomposition is formulated. For a pair of correlation coe cient vectors minimizing powers of spectra is characterized using quadratic programming problem with constraint, where values of powers are non-negative. The solution of the problem without constraint is calc...

PROBLEM ADDRESSED The population is aging rapidly and there are implications for health care delivery in the face of few physicians specializing in care of the elderly (COE). OBJECTIVE OF PROGRAM To train physicians wishing to provide COE services. PROGRAM DESCRIPTION The COE program at the University of Alberta in Edmonton is an enhanced skills diploma program lasting 6 months to 1 year, w...

This paper's main issue is a strong advocacy in favour of an a priori classification of thermal environments that can be really functional to comfort assessment: Class 1, environments where comfort conditions can be established (comfort-prone environments), and Class 2, environments where this is not practically feasible. The former, which are also identified here as 'thermally unconstrained' e...

The goal of this work is to determine appropriate domain and range of the map from the coe cients to the solutions of the wave equation for which its linearization or formal derivative is bounded and the properties of the coe cients on which the bound depends. Such information is indispensable in the study of the inverse (coe cient identi cation) problem via smooth optimization methods. The mai...

This paper provides a review of linear panel data models with slope heterogeneity, introduces various types of random coe¢ cients models and suggests a common framework for dealing with them. It considers the fundamental issues of statistical inference of a random coe¢ cients formulation using both the sampling and Bayesian approaches. The paper also provides a review of heterogeneous dynamic p...

[IrCl(COE)2]2 (1) reacts with pyridine (py) and H2 to form crystallographically characterized IrCl(H)2(COE)(py)2 (2). 2 undergoes py loss to form 16-electron IrCl(H)2(COE)(py) (3), with equivalent hydride ligands. When this reaction is studied with parahydrogen, 1 efficiently achieves hyperpolarization of free py (and nicotinamide, nicotine, 5-aminopyrimidine, and 3,5-lutudine) via signal ampli...
