Selecting two different defective coins q

In this paper, given a balance scale and the information that there are exactly two different defective coins present, the authors consider the problem of ascertaining the minimum number of testing which suffice to determine the two different defective coins in a set of k coins in same appearance, and here k P 3. A testing algorithm for all the possible values of k is constructed, and the testi...

Two-machine robotic cell considering different loading and unloading times

In this paper, the researchers have investigated a Concatenated Robot Move (CRM) sequence problem and Minimal Part Set (MPS) schedule problem with different setup times for two-machine robotic cell. They have focused on simultaneous solving of CRM sequence and MPS schedule problems with different loading and unloading times. They have applied a Simulated Annealing (SA) algorithm to provide a go...

Construction Resource Use of Two Different Types

As global populations and affluence rise, there is increasing demand for energy, animal protein, and construction materials. In many cases, available resource pools are insufficient to meet growing market demands, resulting in increased prices and competition for limited resources. This study evaluates key construction resources needed to build different types and scales of Iowa swine productio...

Linear Spring Oscillator with Two Different Types of Damping

This paper presents a simple, cheap and easily accessible demonstration experiment in two modifications. A typical example of a physical system for which damping forces have to be involved into equations is a damped spring mechanical oscillator. Here we use two models of the damping force, being produced by Foucault currents and by the force of the drag in air. It turns out, maybe as a slightly...
