A highly efficient photovoltaic (PV) system requires a maximum power point tracker to extract peak from PV modules. The conventional variable step-size incremental conductance (INC) tracking (MPPT) technique has two main drawbacks. First, it uses pre-set scaling factor, which manual tuning under different irradiance levels. Second, adapts the slope of characteristics curve vary step-size, means...

6 It has been hypothesized that the insertion of cation preferential channels into 7 neuronal cell membranes disrupts homeostasis and function leading to 8 Alzheimer’s disease. These channels have been shown to be composed of 9 variable numbers of subunits. The nonhomogenous configuration of these 10 subunits in the channels has introduced difficulties in defining set values of ion 11 conductan...

This study examines the ability of neurons to track temporally varying inputs, namely by investigating how the instantaneous firing rate of a neuron is modulated by a noisy input with a small sinusoidal component with frequency (f). Using numerical simulations of conductance-based neurons and analytical calculations of one-variable nonlinear integrate-and-fire neurons, we characterized the depe...

We present an approach for controlling relaxation parameters in variable conductance diffusion. This approach incorporates a Bayesian classifier to perform a partial labeling of an image, followed by a diffusion step. Conductance values between pixels are controlled by statistical measurements made of the partial classification. Several iterations follow, interleaving partial labeling with diff...

This paper describes a partial differential equation for denoising images. The proposed method is demonstrably superior to anisotropic diffusion (and it’s many variations) for denoising images that are approximately piecewise constant. The method relies on an equation that is the level-set equivalent of the anisotropic diffusion equation proposed by Perona and Malik [1]. This proposed equation ...
