New technique helps engineer water filters, human tissues（图）
New technique engineer water filters human tissues
2019/10/22
Scientists at Rutgers University have developed a technique to turn proteins into never-ending patterns that look like flowers, trees or snowflakes. The study, which appears in the journal Nature Chem...
Penn Engineers Develop Filters That Use Nanoparticles to Prevent Slime Build-up（图）
Penn Engineers Filters Nanoparticles Prevent Slime Build-up
2017/11/23
Filtration membranes are, at their core, sponge-like materials that have micro- or nanoscopically small pores. Unwanted chemicals, bacteria and even viruses are physically blocked by the maze of mesh,...
Optimization-based design and implementation of multi-dimensional zero-phase IIR filters
Design automation digital filters infinite-impulse response filters iterative methods multidimensional systems, optimization
2015/8/10
This paper considers multi-dimensional infinite impulse response (IIR) filters that are iteratively implemented. The focus is on zero-phase filters with symmetric polynomials in the numerator and deno...
Wavelength calibration for OSIRIS/GTC* tunable filters
Wavelength calibration OSIRIS/GTC* tunable filters
2011/10/12
OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) is the first light instrument of the Gran Telescopio Canarias (GTC). It provides a flexible and competitive tunable filte...
Evidence-Based Filters for Signal Detection: Application to Evoked Brain Responses
Evoked Brain Responses Bayesian Evidence Brain Machine Interface Optimum Filters
2011/8/3
Abstract: Template-based signal detection most often relies on computing a correlation, or a dot product, between an incoming data stream and a signal template. Such a correlation results in an ongoin...
On sub-ideal causal smoothing filters
smoothing filters casual filters sub-ideal filters Hardy spaces
2011/3/1
Smoothing filters are studied for continuous time processes. The consideration is restricted by the linear causal filters represented as convolution integrals over the historical data. This filters ar...
Path sampling for particle filters with application to multi-target tracking
Path sampling particle filters with application multi-target tracking
2010/12/3
In recent work [15], we have presented a novel approach for improving particle filters for multi-target tracking. The suggested approach was based on Girsanov’s change of measure theorem for stochasti...
Q-type Pseudo- BCI Algebras and 2-type Pseudo- q Filters
Q-type pseudo- BCI algebra pseudo-BCK algebra T-type pseudo- BCI algebra T-type pseudo-BCI filter 2-type pseudo- q filter
2012/9/25
As a generalization of quasi-associative BCI-algebra, the notion of Q-type pseudo- BCI algebra is introduced. The relationship among pseudo- BCK algebra, T-type pseudo- BCI algebra and Q-type pseud...
Developing diagnostics for input-output systems:the effects of certain linear and nonlinear filters on the correlation integral
Developing diagnostics input-output systems linear and nonlinear filters correlation integral
2009/11/16
Input-output systems are characterized by applying time series analysis techniques developed for autonomous systems to the input and the output time series separately and using the results as nonlinea...
Comparison of extended and ensemble based Kalman filters with low and high resolution primitive equation ocean models
Kalman filters low and high resolution primitive equation ocean models
2009/11/11
Kalman filters are widely used for data assimilation into ocean models. The aim of this study is to discuss the relevance of these filters with high resolution ocean models. This was investigated thro...
