Depth, number, and shape of the basins of the potential energy landscape are the key ingredients of the inherent structure thermodynamic formalism introduced by Stillinger and Weber [F. H. Stillinger and T. A. Weber, Phys. Rev. A 25, 978 (1982)]. Within this formalism, an equation of state based only on the volume dependence of these landscape properties is derived. Vibrational and configuratio...

Two adaptive algorithms are presented for robust time delay estimation (TDE) in acoustic environments with a large amount of background noise and reverberation. Recently, an adaptive eigenvalue decomposition (EVD) algorithm has been developed for TDE in highly reverberant acoustic environments. In this paper, we extend the adaptive EVD algorithm to noisy and reverberant acoustic environments, b...

A commonly used method for Acoustic Source Localization is based on Time Delay Estimation (TDE). In general discrete TDE algorithms are used which result in discrete Time Difference of Arrival (TDOA) estimates, i.e. range differences. The Position Location of an acoustic source can be calculated using a set of TDOAs. The accuracy of the position greatly depends upon the accuracy of the estimate...

Time delay estimation (TDE) between the signals received by two or more spatially separated microphones can be used as a means for the passive localization of the dominant talker in applications such as audio-conference. However, in a recent study, it has been shown that reverberation can have disastrous eeects on TDE performance. In this paper , we develop and evaluate a new cepstral preelteri...

In civil engineering, Time Delay Estimation (TDE) is one of the most important tasks for the media structure and quality evaluation. In this paper, the MUSIC algorithm is applied to estimate the time delay. In practice, the backscattered echoes are highly correlated (even coherent). In order to apply the MUSIC algorithm, an adaptation of signal subspace smoothing is proposed to decorrelate the ...

Recently, there has been an increased interest in the use of the time-delay estimation (TDE) technique to locate and track acoustic sources in a reverberant environment. Typically, the delay estimate is obtained through identifying the extremumof the generalized cross-correlation (GCC) function or the average magnitude difference function (AMDF). These estimators are well studied and their stat...

The incorporation of purified neutral protease and class I & class II collagenase isolated from C. histolyticum culture supernatants into defined tissue dissociation enzyme (TDE) mixtures was in part responsible for the success of the Edmonton protocol. The enzyme composition of Liberase HI Purified Enzyme Blend (HI) was determined by using design of experiment methodology to optimize the conce...

Simple, transparent rules are often frowned upon while complex, black-box models seen as holding greater promise. Yet in quickly changing situations, simple can protect against overfitting and adapt quickly. We show that the surprisingly recency heuristic forecasts more accurately than Google Flu Trends (GFT) which used big data analytics a algorithm. This predicts “this week’s proportion of fl...

The influence of the injection system on combustion instabilities is investigated a laboratory-scale combustor equipped with single injector that weakly-transparent to acoustic waves. fed liquid heptane delivered as spray by hollow cone atomizer. Experiments are carried out three swirlers having similar geometries but different pressure losses and swirl numbers. Self-sustained oscillations (SSO...
