The purpose of this study is to test the Brenner hypothesis using a Bayesian vector autoregressive approach, to compute impulse response function and to conclude if evidence of the hypothesis exist in Canadian data.

This paper aims to give a quantitative description of the linguistic acoustic properties, i.e., fundamental frequency and duration, of a seven-tone dialect in Qiyang County (QY hereafter), south of Hunan Province, China. There are seven surface contrasting tones in the QY dialect, a branch of Old Xiang group . No acoustic analysis has been done in the QY dialect so far. What this paper concentr...

The time-variant frequency response function (TV-FRF) uniquely characterizes the dynamic behaviour of a linear timevariant (LTV) system. This paper proposes a method for estimating nonparametrically the dynamic part of the TV-FRF from known input, noisy output observations. The arbitrary time-variation of the TV-FRF is modelled by Legendre polynomials. In opposition to existing solutions, the p...

The current profile along the 126 ns, multi-bunch beam pulse in the Next Linear Collider Test Accelerator (NLCTA) is monitored with fast toroids (rise time -1 ns). Inserted at several positions along the beam line, they allow us to track current transmission as a function of position along the bunch train. Various measurements, such as rise time, current, width, and slope, are made on the digit...

Wind generation is expected to reach substantially higher levels of penetration in the near future. With the converter interface, the rotor inertia of doubly-fed induction generator (DFIG) based wind turbine generator is effectively decoupled from the system, causing a reduction in inertial response. This can be compensated by enabling the DFIG to provide fast frequency response. This paper pro...

The demand for ancillary service is expected to increases significantly in the future GB system as the high penetration of wind generation. In particular, the need for frequency regulation services, required to deal with sudden frequency drops following a loss of large generating plant, will increase due to the limited inertia capability of wind plants. This paper focuses on quantifying the req...

We present a new method for obtaining the response function 9 and its average G from which most of the properties of learning and generalization in linear perceptrons can be derived. We first rederive the known results for the 'thermodynamic limit' of infinite perceptron size N and show explicitly that 9 is self-averaging in this limit. We then discuss extensions of our method to more general l...

| We consider the problem of identifying a n n MIMO system excited by unobservable non-white and spatially independent inputs. Frequency-domain methods always associate a permutation ambiguity to the system frequency response, which unless computed and compensated for, results in an erroneous solution. We show that, from the permutation-dependent solution we can extract some quantities (invaria...

A new method for integrated design of passive and active elements is presented. Rather than the existing qualitative selection of parameters for passive elements, a quantitative approach is proposed which finds optimal active and passive parameters with respect to an H2/H∞ performance requirement. This new approach automatically yields passive designs when the given performance limits are high ...

The current profile along the 126 ns, multi-bunch beam pulse in the Next Linear Collider Test Accelerator (NLCTA) is monitored with fast toroids (rise time ~1 ns). Inserted at several positions along the beam line, they allow us to track current transmission as a function of position along the bunch train. Various measurements, such as rise time, current, width, and slope, are made on the digit...
