In this paper a class of SVD-based signal enhancement procedures is described, which amount to a specific optimal filtering technique for the case where the so-called ‘desired response’ signal cannot be observed. It is shown that this optimal filter can be written as a function of the generalized singular vectors and singular values of a so-called speech and noise data matrix. A number of simpl...

Psychological experiments have shown that human performance on traditional causal reasoning experiments can be greatly influenced by different pretraining and postraining conditions. In this paper we present a Bayesian theory of sequential learning that captures observed experimental results [1] . We implement our theory using the particle filter algorithm, and show that model selection and mod...

Recent developments have allowed x-ray diffraction techniques at synchrotron radiation facilities to be employed with a temporal resolution of around 1 ps. These developments are the availability of firstly, high brightness third-generation x-ray sources, secondly, passively mode-locked lasers with 100 fs temporal duration and thirdly, averaging streak cameras with sub-picosecond temporal resol...

Some techniques which average multiple AMSR satellite data passes into daily sets create images with diminished temporal resolution. This results from averaging data of multiple overlapping passes separated by many hours. Overlap can be reduced by instead grouping data according to local time of day. This new method maximizes temporal resolution by decreasing both the number and the temporal va...

Our approach is among the three best to tackle the M2CAI Workflow challenge. The latter consists in recognizing the operation phase for each frames of endoscopic videos. In this technical report, we compare several classification models and temporal smoothing methods. Our submitted solution is a fine tuned Residual Network-200 on 80% of the training set with temporal smoothing using simple temp...

BACKGROUND Occupational hearing loss and its diagnostic methods are one of the subjects of great interest in the field of occupational medicine and hygiene. The primary aim of the work was to determine the characteristics of ready-made filters used to process the brainstem auditory evoked potentials. No data on the properties of these filters have prompted the author to verify the algorithm of ...

Visual monitoring with CMOS image sensors opens up a variety of new applications for wireless sensor nodes, ranging from military surveillance to in vivo molecular imaging. In particular, the ability to detect motion can enable more intelligent power management through on-demand duty cycling and reduced data-retention requirements. Conventional imager designs focus on achieving higher resolutio...

Introduction The local specific absorption rate (SAR) becomes a limiting factor for many MR imaging applications with increasing field strength. However, tailoring of the underlying electric fields (E-fields) in the RF pulse design process is possible when using parallel Tx systems. Different approaches exist to reduce SAR in parallel transmission. Minimal SAR RF pulses can be selected from the...

Under a variety of conditions, motion in depth from binocular cues is harder to detect than lateral motion in the frontoparallel plane. This is surprising, as the nasal-temporal motion in the left eye associated with motion in depth is easily detectable, as is the nasal-temporal motion in the right eye. It is only when the two motions are combined in binocular viewing that detection can become ...

Patterns of low temporal turnover in species composition found within paleoecological time series contrast with the high turnover predicted by neutral metacommunity models and thus have been used to support nonneutral models. However, these predictions assume temporal resolution on the scale of a season or year, whereas individual fossil assemblages are typically time averaged to decadal or cen...
