Shape memory alloys (SMAs) are a class of smart materials characterized by shape memory effect and pseudo-elastic behavior. They have the capability to retain their original form when subjected to certain stimuli, such as heat or a magnetic field. These unique properties have attracted many researchers to seek their application in various fields including transportation, aerospace, and biomedic...

Transportation of unrefined crude oil from the production unit to a refinery or large storage area by a pipeline is difficult due to the different properties of crude in various areas. Thus, the design of a crude oil pipeline is a very complex and time consuming process, when considering all the various parameters. There were three very important parameters that play a significant role in the t...

Maritime transportation is an important industry, with seaborne trade estimated to be up to 85% in terms of weight of total international trade in 2007. Capital investment for ships is substantial, and the operating costs of a ship may range from thousands to tens of thousands of US dollars daily, thus the potential benefits of optimized approaches to fleet planning are significant. Despite thi...

this study by the first, was carried out to evaluate and comparing disposal waste management in karaj's hospitals in 1387. interview and observation methods were used to collect data and the study tool was a questionnaire. data were analyzed by the spss, using chi-square and t-test. regarding the condition of infectious waste generation, 64% of the hospitals had a good grade. source separa...

In this paper some research questions which potentially lie within the purview of the new discipline of Computational Transportation Science are presented. Some of these questions are no doubt old and jaded and some may rightly reside in a different research field (or be seen as engineering) but viable solutions to all of the issues presented are of vital importance to the efficacy of future tr...

The article considers problems of a transport complex mining and processing plants. Requirements for quarry are presented. production process technological operations the transportation considered. ways solving determined. It is established that when creating rational system transporting iron ore raw materials, it possible to reduce material costs losses during transportation.

sustainable road transportation requires integration with economic, social and environmental aspects of transportation. it depends on term and condition of each society. in the recent decades, transportation is growing fast in iran and isfahan follows this scenario. the aim of this study is to study the traffic, parking road properties of isfahan metropolitan area who are actively implementing ...

This paper proposes a tripartite framework of transportation, transformation and translation to conceptualise the circulation, mutation and impacts of mobile policies as translocal, socio-material networks. Drawing on material from semi-structured interviews, participant observation and documents it considers the value of this framework by examining the mobility of the sustainability agenda of ...

agers may organise the collection of resources and their transportation back to the nest. One way is to partition the task into a number of sequential stages in which material is passed from one worker to another in a relay fashion. This relatively new concept is known as task partitioning. In this study, we focus on a particular form of task partitioning, bucket brigades, which we define as a ...
