We present simulations, without electrodynamical assumptions, of Bsx, y, Hstdd, MsHstdd, and JcsHstdd in hard superconductors for a variety of twin-boundary pinning potential parameters, and for a range of values of the density and strength of the pinning sites. We numerically solve the overdamped equations of motion of up to 10 flux-gradient-driven vortices which can be temporarily trapped at ...

Large-lot exurban landscapes could incorporate ecological design in order to contribute ecosystem services. In our study, we use a survey of 126 Southeast Michigan homeowners to examine respondents’ stated preferences for residential yard images, and compare those with reported current use and management of their actual yards. We found that stated preferences are not necessarily related to actu...

In a modern rail–rail transshipment yard huge gantry cranes transship containers between different freight trains, so that hub-and-spoke railway systems are enabled. In this context, we consider the transshipment yard scheduling problem (TYSP) where trains have to be assigned to bundles, which jointly enter and leave the yard. The objective is to minimize split moves and revisits. Split moves a...

This paper reports the findings of using multi-agent based simulation model to evaluate the sawmill yard operations within a large privately owned sawmill in Sweden, Bergkvist Insjön AB in the current case. Conventional working routines within sawmill yard threaten the overall efficiency and thereby limit the profit margin of sawmill. Deploying dynamic work routines within the sawmill yard is n...

Yard crane is an important resource in container terminals. Efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. This paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is NPHARD in nature. In other words, one of the most important constraints in...

In this paper, we address workflow management system for automatically operating yard management system which can fill up a gap between transportation and warehouse management system in supply chain management. But, it is difficult to find an optimal solution for yard operation problems because of its dynamic complexities. Instead, we propose workflow management system which describes the autom...

There is need for proper understanding of plant nutrients status in the soil and their requirements by various crops under different farming system. Farmers must be encouraged to make compost from residues, house refuse and other decomposable wastes available with them. If crop residues have been incorporated into the soil, care must be taken that it must be incorporated well in advance (about ...

This reasearch studies ACO algorithms for the switch engine scheduling in a Railroad Yard. The cars are moved individually or grouped into blocks by a set of locomotives called switch engines which are dedicated to moving around the cars in the yard. The need for moving comes from the fact that the arriving trains are disassembled into blocks of cars, undergo some operations like, loading , unl...

This paper investigates the traditional production process that defines perfect symbiosis between site, culture, and construction engineering lifestyle. Indeed, despite limited means, ancient builders have erected collective edifices well adapted suited to occupants' needs. study aims assess auressian clusters investigate relationship space resident community establish a reference cultural mode...
