Aquifer hydraulic parameters play a critical role in investigating various groundwater hydrology problems (e.g., depletion and transport), the Theis formula for constant-rate pumping tests is commonly used to estimate them. However, rate field usually varies with time due some factors, making classical model unsuitable accurate parameter estimation. To address this issue, we developed novel dim...

This study presents an almost entirely unpublished dataset of 121 samples groundwater analyzed for helium concentration and its isotopic ratio (3He/4He) in two adjacent watersheds the St. Lawrence Lowlands, a region with intensive agricultural activities southern Québec Province, Eastern Canada. Most were collected regional bedrock fractured aquifer hosted mid-Ordovician siliciclastic shales, o...

Boreholes are the most versatile and technically advanced structural type of water intake structures. In this article, authors propose design a well with filters located at two levels, capable simultaneously performing functions working reserve wells, use which will reduce energy consumption for lifting water, capital investments construction ensure uninterrupted supply. The methodology calcula...

The central part of the fingerpad in anesthetized monkeys was stimulated by spheres varying in curvature indented into the skin. Responses were recorded from single slowly adapting type I primary afferent fibers (SAIs) innervating the sides and end of the distal segment of the stimulated finger. Although these afferents had receptive field centers that were remote from the stimulus, their respo...

When a human grasps a cylindrical object, feedback on the orientation of the cylinder with respect to the axes of the digits is crucial for successful manipulation of the object. We measured the ability of humans to discriminate the orientations of cylinders passively contacting the fingerpad. For a cylinder of curvature of 521 m-1 (radius, 1.92 mm) subjects were able to discriminate, at the 75...

....... An Automatic Identification System (AIS) capability on the RADARSAT Constellation Mission (RCM) will enhance the Canada First Defence Strategy goals of conducting national and continental operations and defending Canada. Key to understanding this is the ability to model and simulate satellite AIS (SAIS) performance characteristics. This report provides an overview of a statistical model...

Transition from endorheic alluvial fan environments to well-channelized fluvial systems in natural conditions may occur in response to base-level fluctuations. However, human-induced changes in semi-arid regions can also be responsible for similar unforeseen modifications. Our results confirm that in-channel gravel mining and aquifer overexploitation over the last 50 years in the case study are...

The deep learning-based coding schemes for lenslet images combine standards and view synthesis through Deep Learning (DL) models, where the compression efficiency is heavily influenced by structure quality of synthesized views. To exploit inter-view redundancy among Sub-Aperture Images (SAIs), this paper proposes a hybrid closed-loop system that uses novel based on checkerboard interleaving at ...

Abstract—Adequate and reliable estimates of aquifer parameters are of utmost importance for proper management of vital groundwater resources. At present scenario, the ground water is polluted because of industrial waste disposed over the land and the contaminants are transported in the aquifer from one area to another area, which is depending on the characteristics of the aquifer and contaminan...
