Transit sets of -point crossover operators [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
-point crossover operators and their recombination sets are studied from different perspectives. We show that transit functions of -point crossover generate, for all , the same convexity as the interval function of the underlying graph. This settles in the negative an open problem by Mulder about whether the geodesic convexity of a connected graph is ...

Optimization of Train Operation Organization during Metro Catenary Collapse

open access: yesChengshi guidao jiaotong yanjiu
[Objective] In the event of a collapsed non-redundant rigid catenary, it is essential to adjust train operation organization according to different collapse scenarios, minimizing the impact of the incident and reducing property losses as much as possible.

Influence of Urban Rail Transit Interchange Station Location on Passenger Interchange Route Selection

open access: yesChengshi guidao jiaotong yanjiu
Objective There are some non-quantifiable factors in the actual travel of passengers in urban rail transit (such as the position of interchange stations in the line network), which are challenging to quantify and convert into impedance in the multi-route

Construction of a Prediction Model for Energy Consumption in Urban Rail Transit Operations Using a Bottom–Up Approach

open access: yesEnergies
Global climate change necessitates an immediate reduction in carbon emissions. This study aimed to categorize rail transit energy consumption factors into “traction energy consumption” and “non-traction comprehensive energy consumption” by employing a ...

Canadian transit agencies response to COVID-19: Understanding strategies, information accessibility and the use of social media

open access: yesTransportation Research Interdisciplinary Perspectives, 2021
Over the past few months, transit agencies across Canada have been rushed to implement a range of strategies in response to the COVID-19 pandemic, with no standardized guidelines to direct their efforts.

Research on Urban Rail Transit Passenger Flow Prediction Method during Dispersal Period of Large-scale Events

open access: yesChengshi guidao jiaotong yanjiu
ObjectiveIn recent years, hosting large-scale events has become an important means to stimulate consumption for cities and a key aspect of developing new cultural tourism. In the face of more frequent large-scale events and higher safety standards, urban

Eco-conscious decision-support model for optimizing stopping patterns in the mass transit system

open access: yesEngineering and Applied Science Research, 2022
The existing train operational efforts focus on need-based criteria for serving passenger demand while maintaining travel time satisfaction. Although mass transit contributes to reduced private vehicle fuel consumption, the current mass transit ...

Transition Operators Assigned to Physical Systems [PDF]

open access: yesReports on Mathematical Physics, 2016
By a physical system we recognize a set of propositions about a given system with their truth-values depending on the states of the system. Since every physical system can go from one state in another one, there exists a binary relation on the set of states describing this transition.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
