Abstract
This paper presents the result of a study evaluating
the influence of alternative path generation strategy
on structure and some mechanical properties of parts
produced by Fused Deposition Modeling (FDM) technology.
Several scientific investigations focused on resolving
issues in FDM parts by modifying a path generation strategy
to optimize its mechanical properties. In this study,
an alternative strategy was proposed with the intention of
minimizing internal voids and, thus, to improve mechanical
properties. Polycarbonate samples made by this alternative
path generation strategy were subjected to tensile
strength test and metro-tomography structure evaluation.
The results reveal that the structure observed on
build models differs from a structure expected from path
generation predicted by software Insight 9.1. This difference
affected the tensile strength of samples.
The artificial intelligence undergoes an enormous development since its appearance in the fifties. The computing power has grown exponentially since then, enabling the use of artificial intelligence applications in different areas. Since then, artificial intelligence applications are not only present in the industry, but they have slowly conquered households as well. Their use in logistics is becoming more and more widespread, just think of self-driving cars and trucks. In this paper, the author attempts to summarize and present the artificial intelligence logistical applications, its development and impact on logistics.
Abstract
The paper discusses the spatial consequences of the widespread use of self-driving cars and the resulting changes in the structure of urban areas. Analysing present knowledge on the technology, functionality and future forms of organisation of mobility with this type of means of transportation, conclusions are presented concerning the expected changes in the organisation of space in urban areas. The main achievement of the investigation is an outline of the fields of future research on the spatial consequences of a transportation system with a large share of self-driving cars.
