Pseudocapacitance is an important reversible charge storage mechanism in many electrode materials. Although the concept was first proposed early 1960s, it has been more widely studied following observation of rectangular cyclic voltammograms (CVs) when testing some transition metal oxides and electronically conducting polymers, association with supercapacitor. However, interpretation pseudocapa...

This paper presents a new recursive filter to joint input and state estimation for noisy discrete time Takagi-Sugeno (T-S) fuzzy models. For each local linear model one local filter is designed using Kalman filter theory. Steady state and unknown input solutions can be found for each of the local filters. The global filter is a linear combination of linear filters. The local filter is time inva...

Witkin proposed that the convolution of a signal Visual tasks often require a hierarchical representation of with a Gaussian removes small-scale features, namely, shapes and images in scales ranging from coarse to fine. A zero-crossings, while retaining the more significant ones variety of linear and nonlinear smoothing techniques, such as [88]. Koenderink showed that among the linear ...

In classical signal processing, it is common to analyze and process signals in the frequency domain, by representing the signal in the Fourier basis, and filtering it by applying a transfer function on the Fourier coefficients. In some applications, it is possible to design an optimal filter. A classical example is the Wiener filter that achieves a minimum mean squared error estimate for signal...

Receiver architectures in the form of a linear filter front-end followed by a hard-limiting decision maker are considered for DS-CDMA communication systems. Based on stochastic approximation concepts a recursive algorithm is developed for the adaptive optimization of the linear filter front-end in the minimum BER sense. The recursive form is decision driven and distribution free. For additive w...

When a hazardous substance is diffused, it is necessary to identify the pollutant source and respond immediately. However, there are many cases in which damage is caused without a clear understanding of where the pollutant source is located. There are three groups of identifying pollutant source information Liu and Zhai, 2007 : the probability method, forward method, and backward method. In our...

Diffusion tensor imaging (DTI) is a promising biomarker of spinal cord injury (SCI). In the acute aftermath, DTI in SCI animal models consistently demonstrates high sensitivity and prognostic performance, yet translation of DTI to acute human SCI has been limited. In addition to technical challenges, interpretation of the resulting metrics is ambiguous, with contributions in the acute setting f...
