up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. graphene, a new class of 2d carbonaceous material with atom thi...

Solar cells are devices that convert solar energy (including photons) into electrical energy. They a renewable source and have great potential to overcome the needs of society due simple manufacturing process with which they can be manufactured, reasonable efficiency, as well customizable aesthetic appearance. Natural colors color it in. However, researchers still struggling market its low purc...

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...
