In speech recognition systems, feature extraction can be achieved in two steps: parameter extraction and feature transformation. Feature transformation is an important step. It can concentrate the energy distributions of a speech signal onto fewer dimensions than those of parameter extraction and thus reduce the dimensionality of the system. Linear Discriminant Analysis (LDA) and Principal Comp...

Radar systems have been widely explored as a monitoring tool able to assess the subject’s vital signs remotely. However, their implementation in real application scenarios is not straightforward. Received signals encompass parasitic reflections that occur environment. Generally, those components, often treated complex DC (CDC) offsets, must be removed order correctly extract bio-signals informa...

We report evidence of nonequilibrium hot carrier extraction from graphene by gate-dependent photocurrent study. Scanning photocurrent excited by femtosecond pulse laser shows unusual gate dependence compared with continuous wave (CW) laser excitation. Power dependence studies further confirm that the photocarriers extracted at the metal/graphene contact are nonequilibrium hot carriers. Hot carr...

McAfee and Reny (1992) have given a necessary and sufficient condition for full surplus extraction in naive type spaces with a continuum of payoff types. We generalize their characterization to arbitrary abstract type spaces and to the universal type space and show that in each setting, full surplus extraction is generically possible. We interpret the McAfee-Reny condition as a much stronger ve...

Linseed flax is a multipurpose crop. It cultivated for its seeds and particularly oil. The main contributors this crop are Canada, France Belgium. In general, straws of linseed buried in the fields or burnt. However, these solutions not good practices environment from an economical point view. study, (six batches total) with different dew retting durations harvesting techniques were studied to ...
