We report an experimental implementation of long-range polarimetric imaging through fog over kilometric distance in real field atmospheric conditions. An incoherent polarized light source settled on a telecommunication tower is imaged at a distance of 1.3 km with a snapshot polarimetric camera including a birefringent Wollaston prism, allowing simultaneous acquisition of two images along orthog...

Now a days, 532 nm Laser whose spectrum is visible in nature, used different applications like Lidar, optical wireless communication, in-car headlight projector to detect the object and reduce accident foggy weather conditions, as pilot laser for alignment non-visible infrared of OWC link purpose, etc. Different states India, well West Bengal, faces especially winter season. This environment ca...

This study investigated abnormalities of the first three steps of gait initiation in patients with Parkinson's disease without freezing of gait (PD - FOG) and investigated which abnormalities are related to FOG. Seven PD - FOG and seven age-matched healthy controls performed self-generated or cue-triggered gait initiation. Data for PD patients with FOG (PD + FOG) were cited from a previous stud...

We present a computational model of altered gait velocity patterns in Parkinson's Disease (PD) patients. PD gait is characterized by short shuffling steps, reduced walking speed, increased double support time and sometimes increased cadence. The most debilitating symptom of PD gait is the context dependent cessation in gait known as freezing of gait (FOG). Cowie et al. (2010) and Almeida and Le...

This paper aims to measure and analyze of the leakage current of 20 kV polymer and porcelain metal oxide surge arresters under humid ambient conditions by applying different voltages to the arresters terminal. The characteristics of the leakage currents at that stage have been investigated when changes in the ambient humidity were introduced in an artificial fog chamber. It is assumed that magn...

Authentication is an important and challenging issue for the security of Fog computing since, services are offered to massive-scale end users (Fog users or Edge) by front Fog servers (or Fog nodes). In this paper, we propose a secure and efficient mutual authentication scheme for the EdgeFog-Cloud network architecture, to mutually authenticate Fog users at the Edge of the network, with the Fog ...

Freezing of gait (FOG) is a complicated gait disturbance in Parkinson's disease (PD) and a relevant subclinical predictor algorithm is lacking. The main purpose of this study is to explore the potential value of surface electromyograph (sEMG) and plasma α-synuclein levels as predictors of the FOG seen in PD. 21 PD patients and 15 normal controls were recruited. Motor function was evaluated usin...

Image restoration is an important topic in the area of image processing because its techniques are useful to recover images degraded during a capturing process (Bovik, 2005). There are a wide range of degradations in real world, such as blurring (i.e. camera motion capture process), nonuniform illumination, cloud environments (fog, clouds, smoke), noise (white noise, impulse noise, etc.), and d...
