This paper introduces a new method of electricity generation using Wiegand sensor. The sensor consists magnetic wire and pickup coil wound around it. generates pulse voltage approximately 5 V 20 µs width as an induced in the coil. aim this study is to generate DC from sensor, which expected be used power source self-powered devices battery-less modules. We report on design verification self-osc...

This paper presents a review on edge-preserving decomposition based image haze removal. When the background has dust particles or hazes its image quality and color is degraded. It is well-known that local filtering-based edge preserving smoothing method suffers from halo artifacts. In this paper a survey of many different methods for haze removal just like Laplacian-based visibility restoration...

This paper addresses the voltage droop compensation associated with long pulses generated by solid-stated based high-voltage Marx topologies. In particular a novel design scheme for voltage droop compensation in solid-state based bipolar Marx generators, using low-cost circuitry design and control, is described. The compensation consists of adding one auxiliary PWM stage to the existing Marx st...

Two numerical methods for the restoration of noisy images from the Hubble Space Telescope are presented. The first one stems from a B-spline expansion followed by the Tikhonov regularization method. The second one is based on a coarse smoothing coupled with the Tikhonov regularization. The effectiveness of these methods is illustrated by the restoration of some images already proposed in the li...

Inpainting and denoising are two important tasks in the field of image processing with broad applications in image and vision analysis. In this paper, we present a new approach for image restoration. Our method simultaneously fills in missing, corrupted, or undesirable information while it removes noise. The denoising is performed by the smoothing equation working inside and outside of the inpa...

In this correspondence, a constrained least-squares multichannel image restoration approach is proposed, in which no prior knowledge of the noise variance at each channel or the degree of smoothness of the original image is required. The regularization functional for each channel is determined by incorporating both within-channel and cross-channel information. It is shown that the proposed smoo...

In this paper we extend nonlocal smoothing techniques for image regularization in [12] to surface regularization, with surfaces represented by level set functions. We test our algorithm on both phantom and observed surfaces, including city terrain and cortical surfaces.

It has been shown in literature that adaptive regularized image restoration is superior to non-adaptive one. However, the adaptivity introduced in most proposed iterative algorithms is based only on the application of space-variant smoothing operator. It is found that these adaptive algorithms su er from insu cient smoothing of the at image regions. In this paper, an adaptive iterative image re...

Active three-phase rectifier systems usually cover a wide field of applications where high total power factor (99%+) and low mains current THDi (typ. <5%) are required. Passive three-phase rectifiers on contrary are characterized as highly efficient and robust whereas their power factor is limited to 0.9...0.95 due to rather high harmonic input current components (THDi up to 48%). This paper an...
