Axiomatic characterization of the interval function of partial cubes and partial Hamming graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
Interval function of a graph is a well-known notion in metric graph theory and the axiomatic characterization using a set of first order axioms of different graph classes is an interesting problem in this area.

Using accessibility measures in transit network design

open access: yesTransport, 2018
Transit planning scenarios may lead to the different Objective Function (OF) values since each scenario has different transit travel times, frequencies and fleet sizes.

Outdoor Atmospheric Microbial Diversity Is Associated With Urban Landscape Structure and Differs From Indoor-Transit Systems as Revealed by Mobile Monitoring and Three-Dimensional Spatial Analysis

open access: yesFrontiers in Ecology and Evolution, 2021
Microbes are abundant inhabitants of the near-surface atmosphere in urban areas. The distribution of microbial communities may benefit or hinder human wellbeing and ecosystem function.

Directed Transit Functions

open access: yesResults in Mathematics
Abstract Transit functions were introduced as models of betweenness on undirected structures. Here we introduce directed transit function as the directed analogue on directed structures such as posets and directed graphs. We first show that betweenness in posets can be expressed by means of a simple set of first order axioms.

Circuity in Urban Transit Networks [PDF]

open access: yes, 2015
This paper investigates the circuity of transit networks and examines auto mode share as a function of circuity and accessibility to better understand the performance of urban transit systems. We first survey transit circuity in the Minneapolis–St. Paul,

Prediction of Daily Entrance and Exit Passenger Flow of Rail Transit Stations by Deep Learning Method

open access: yesJournal of Advanced Transportation, 2018
The prediction of entrance and exit passenger flow of rail transit stations is one of key research focuses in the area of intelligent transportation. Based on the big data of rail transit IC card (Public Transportation Card), this paper analyzes the data

Microsimulation of Flexible Transit System Designs in Realistic Urban Networks [PDF]

open access: yes, 2005
The use of microsimulation is not prevalent in modeling transit systems. The software available is rarely capable of modeling transit systems that route vehicles in real time or systems that adjust to the level of demand.

Transit functions and clustering systems

open access: yesThe Art of Discrete and Applied Mathematics
Transit functions serve not only as abstractions of betweenness and convexity but are also closely connected with clustering systems. Here, we investigate the canonical transit functions of binary clustering systems inspired by pyramids, i.e., interval hypergraphs.

On the Bessel function in the transition region [PDF]

open access: yesLMS Journal of Computation and Mathematics, 2014
AbstractWe give an approximation for the value of the Bessel function $J_\nu (x)$ in the transition region with an explicit sharp error term.
