Rajasthan's Bikaner District, part of the Thar Desert, is experiencing problems with falling groundwater levels, high salinity, fluoride and nitrate concentrations. Therefore, quality studies are underway to determine suitability for drinking purposes in district. Quality analysis performed using parameters such as Conductivity (EC), Total Dissolved Solids (TDS), pH, Calcium, Potassium, Sodium,...

This paper considers a scheduling problem for a single burn-in oven in the semiconductor manufacturing industry where the oven is a batch processing machine with restricted capacity. The batch processing time is set by the longest processing time among those of all the jobs contained in the batch. All jobs are assumed to have the same due date. The objective is to minimize the sum of the absolu...

A K-surface is a surface whose Gauss curvature K is equal to a positive constant. In this paper, we will consider K-surfaces that are defined by a nonlinear boundary value problem. In this setting, existence follows from some recent results on nonlinear second-order elliptic partial differential equations. The analytical techniques used to establish these results motivate effective numerical me...

An efficient optimization algorithm is proposed for designing causal stable perfect-reconstruction two-channel infinite impulse response filter banks originally introduced by Basu, Chiang, and Choi. The problem is stated as a constrained optimization problem where the maximum of the stopband energies of the analysis filters is minimized subject to the given constraints. First, the maximum allow...

Sudden falls of large-area hard roofs in a mined area release a large amount of elastic energy, generate dynamic loads, and cause disasters such as impact ground pressure and gas outbursts. To address these problems, in this study, the sleeve fracturing method (SFM) was applied to weaken a hard roof. The numerical simulation software FLAC3D was used to develop three models based on an analysis ...

A priority queue, a container data structure equipped with the operations insert and delete-minimum, can re-order its input in various ways, depending both on the input and on the sequence of operations used. If a given input σ can produce a particular output τ then (σ, τ) is said to be an allowable pair. It is shown that allowable pairs on a fixed multiset are in one-to-one correspondence with...

Long reach and small diameter manipulators are ideal for borehole deployments into search and rescue scenarios and fragile historical environments. Small diameter passageways impose constraints on a snake arm manipulator which severely limit its performance and capabilities. This work investigates the effects of tendon tensions on the maximum working length of a snake arm under tight size const...
