We performed a large-scale mapping observation toward the W33 complex and its surroundings, covering an area of $1.3^\circ \times 1.0^\circ$ , in $^{12}$CO (1-0), $^{13}$CO C$^{18}$O (1-0) lines from Purple Mountain Observatory (PMO). found new hub--filament system ranging 30 to 38.5 \kms located at complex. Three supercritical filaments are directly converging into central hub W33. Velocity gr...

HUB SIAASHING is a knowledge-based system that recommends contingency plans for American Airlines System Operations Control (SOC) during inclement weather or other airport disruptions where severe schedule reductions must be made. The system evaluates the current situation to determine flight cancellation, delay, and overfly candidates that will provide relief at the hub airport with minimal im...

As a typical discrete element dynamic system (DEDS), railway container hub scheduling system has the characteristic of high randomness, low flexibility, uncertainty of operation time and high coordination demand of facilities. In this paper, according to the analysis of layout, establishment, facility and operation procedure of railway container hub, we choose Multiagent systems (MAS) which hav...

This paper presents a stochastic bi-objective model to reduce the operation cost and carbon emission of smart railway station along with dependent commercial buildings, according multi-energy hub system's structure. The proposed energy system (EHS) includes power, heating, cooling subenergy hub. recovered obtained from regenerative braking (RB) during train deceleration is utilized supply load ...

Living systems rely on chains of energy transfer from an energy source to maintain their metabolism. This task requires functionally identified components and organizations. However, propagation of a sustained energy flux through a cascade of reaction cycles has never been reproduced at a steady state in a simple chemical system. By using energy patterning and a diffusing hub reactant, we achie...

the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

This paper addresses the principal service aspects for electric vehicles (EV), as well as issues related to energy storage design, charging station integration into power system and load management issues. It builds on the research conducted in the Flexible Electric Vehicle Charging Infrastructure project (Flex-ChEV) supported by the ERA-Net Smart Grid FP7 program. The principal asset of the pr...

in this paper, a robust model presented is developed for hub covering flow problem in which hubs have capacity. this problem has two objective functions converting to a single-objective problem by using weighting method. firstly, the problem will be formulated in a certain case. then, by considering the demand as a non-random variable, it will be modeled by robust optimization. finally, by usin...
