Negation is intrinsic to human thinking and most of the time when searching for something, we base our patterns on both positive and negative conditions. This should be naturally reflected in software that provide pattern-based searches. We would like for example to specify that we search for white cars that are not station wagons, or that we search for a list of objects that does not contain t...

The paper presents a planning process, a decision support system and an optimization model designed for the tactical planning of transportation by a logistics service provider (LSP) for customers from the automotive industry focusing on the primary target of sustainable transportation. Therefore a rolling to-be planning process has been designed which covers the planning activities for differen...

The following article describes the logistics analysis on one of the commonly detected problems in trains, associated with BINPACKING, as it is, the wagon’s load, by transporting precious materials extracted from the mines in the state of Chihuahua, as they are: gold ingots, silver ounces and precious gemstones, it has also analyzed the supplies transportation for subterranean mining in the sta...

OBJECTIVE Examine the current magnitude of the injury problem to children and adolescents on farms, and to compare these data to that from 1978-83. DATA SOURCES US National Center for Health Statistics Mortality Multiple Cause of Death Tapes for the years 1991-3, and the US Consumer Product Safety Commission National Electronic Injury Surveillance System for data on emergency department visit...

Methods for estimating a car's length are presented in this paper, as well as the results achieved by using a self-designed system equipped with two anisotropic magneto-resistive (AMR) sensors, which were placed on a road lane. The purpose of the research was to compare the lengths of mid-size cars, i.e., family cars (hatchbacks), saloons (sedans), station wagons and SUVs. Four methods were use...

Almost 50 years ago, the National Heart, Lung, and Blood Institute launched the journey of mechanical circulatory support. These pioneers have included innovative engineers, cardiac surgeons, and stalwart patients accompanied by devoted families, who together have led us to a horizon where widespread clinical utilization is finally within sight. The pace of progress is always slower than projec...

Routing and Makeup problems, determine the routing and frequency of trains & the assignment of blocks to trains, but do not take scheduling into consideration. Consequently later on, it may be difficult to find a timetable accommodating all planned trains and satisfying line and station capacity. As an attempt to settle this issue, both the routing & the scheduling of freight transportation hav...

The aim of the study is to select rational axle loads rolling stock and establish conditions for their circulation on railways Republic Uzbekistan. In this work, research has been carried out assess indicators stress-strain state rail track elements from action with various axial loads. dynamic wheel rail, tensile stresses at edges foot, in wooden sleepers (rubber under-rail pads reinforced con...

Long rails are normally used in highspeed railways to minimize the number of rail joints and dynamic impact force that follows. However, transporting long using a freight train requires multiple wagons for each section, presenting potential safety loading gauge issues, especially when going through curves. Thus, assessment needs be done prior actual transport. Computational simulation can preli...

Measuring the structure gauge of tunnels and other narrow passages has so far been the only way to evaluate whether large vehicles can pass through them. But especially for very long vehicles like train wagons and their cargo, the structure gauge is an insufficient measure because the center part of the vehicle between two bogies will inevitably leave the swept volume of its cross section when ...
