Pregnancy diagnosis is widely practiced in cattle production systems. Ultrasonography is an alternative technique to rectal palpation for pregnancy diagnosis. Fetal losses caused by rectal palpation are well documented; however, reported losses from ultrasonography for pregnancy diagnosis are often confounded by normal embryonic losses during early gestation. Losses caused by inexperienced tech...

BACKGROUND There are many implant cases in which dental technicians take initiative with regard to the design of implant prostheses, and to a certain extent, this area of care is one in which dentists do not necessarily play the leading role. Moreover, inadequate communication between dental technicians and dentists and insufficient instructions for technicians has been highlighted as issues in...

In this paper an emergency service vehicle (ESV) location problem has been considered in which it is assumed that each emergency call may require more than one ESV. In ESV location problem two factors should be known; the location of stations and the number of ESVs at each station. Hence, a nonlinear mixed integer programming model is presented in order to maximize the total response rate to th...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

Initial fault detection and diagnostics are imperative measures to improve the efficiency, safety, stability of vehicle operation. In recent years, numerous studies have investigated data-driven approaches process using available data. Moreover, methods employed enhance customer-service agent interactions. this study, we demonstrate a machine learning pipeline automated diagnostics. First, Natu...

Maintenance for rooftop packaged air conditioners (RTUs) is a rare preventative practice. Generally, service calls are limited to emergency response for major system failures that impact occupant comfort. Even in the case of equipment maintained under service contracts, technicians will only detect severe and obvious faults since their procedures typically only involve routine qualitative asses...

The field of Remote Vehicle Diagnostics can be described as the remote management of vehicles equipped with electronic control systems. Despite the great potential that is ascribed Remote Vehicle Diagnostics there are few practical applications that address the needs of end-users. This paper asks how service mechanics remotely can get detailed vehicle data when the driver is concerned about the...

A vehicle routing problem is a significant problem that has attracted great attention from researchers in recent years. The main objectives of the vehicle routing problem are to minimize the traveled distance, total traveling time, number of vehicles and cost function of transportation. Reducing these variables leads to decreasing the total cost and increasing the driver's satisfaction level. O...
