We study a distribution warehouse in which trailers need to be assigned to docks for loading or unloading. A parking lot is used as a buffer zone and transportation between the parking lot and the docks is performed by auxiliary resources called terminal tractors. Each incoming trailer has a known arrival time and each outgoing trailer a desired departure time. The primary objective is to produ...

operating effectively in factories for decades. These vehicles have successfully used strategies of deliberately structuring the environment and adapting the process to the automation. The potential of computer vision technology to increase the intelligence and adaptability of AGVs is largely unexploited in contemporary commercially-available vehicles. We developed a virtually infrastructure-fr...

The United States Government does not endorse products or manufacturers. Trade or manufacturers' names appear only because they are considered essential to the object of this report. This report evaluates the effectiveness of retroreflective tape in enhancing the visibility of heavy trailers and reducing side and rear impacts by other vehicles into these trailers during dark conditions. It is b...

This study uses TruckSimTM to model disc brakes and drum on a fully loaded truck semi-trailer the performance of each brake type as downgrades speeds vary. The is measured based braking distance. A simplified economic comparison life cycle cost analysis determine which road vehicle conditions give rise cost-effectiveness performed. studies suggest that shorten distances by 10-20%. They also per...

The causes of PM2.5 is dynamic and systematic. However, many studies approach the problem by focusing only on either socioeconomic factors or geo-meteorological in isolation such data insufficiency might undermine effort to control PM2.5. We propose a LSTM-XGBoost model composing both together improve monitoring system. forecast weekly concentrations five regions Taiwan based machine learning t...

Culminating with Time's announcement that 2006's " Person of the Year " was " You, " much of the hoopla surrounding Web 2.0's multiple sharing sites, such as YouTube, IFilm, and MySpace, has focused on how they challenge corporate culture and logic, opening up cultural production, authorship, and distribution to seemingly anyone. Certainly, as Viacom's 2007 $1 Billion-plus lawsuit against YouTu...

CONTEXT Anthropogenic vectors enhance the natural dispersal capacity of plant seeds significantly in terms of quantity and distance. Human-mediated seed dispersal (i.e. anthropochory) greatly increases the dispersal of crop species across agroecosystems. In the case of oilseed rape (OSR), spillage of seeds from grain trailers during harvest has never been quantified. METHODS Our experimental ...

We study the minimum time problem for a simplified model of ship towing long spread cables. Constraints are on curvature trajectory as well shape what represent cables here. This turns out to be same cart two trailers and rolling without sleeping plane in uniform translation. analyse Hamiltonian system describing extremal flow given by Pontrjagin maximum principle. detail equilibria prove that,...

In this study, real-time performance of typical refrigerated trailers used in food transportation industry is studied theoretically and experimentally. Two pilot refrigerated trailers are selected and real-time data are collected over different seasons of year 2014–2015 using various measuring equipment during routine operation (fleet dairy distribution reefers) in Vancouver, BC, Canada. A new ...
