Public transport system must be profitable to the private operators without government subsidy or intolerable rise in bus fare to ensure efficient mobility in a third world city. However, a populist but not so affluent government is unwilling either to subsidize or raise the bus fare, thereby forcing private players to withdraw or compromise with the level of service and the commuters are badly...

We have begun to see the emergence of large-scale knowledge bases that house tens of thousands of facts encoded in expressive representational languages. The richness of these representations o er the promise of signi cantly improving the quality of natural language generation, but their representational complexity, scale, and task-independence pose great challenges to generators. We have desig...

Demand forecasting is a crucial component of revenue management, as forecasts are almost always inputs into optimization routines for pricing decisions. The performance of many revenue management systems often depends critically on the quality of demand forecasts. Indeed, industry estimates suggest that a 20% reduction of forecast error may lead to 1% incremental increase in revenue (Talluri an...

Linear-quadratic controllers for tracking natural and composite trajectories of nonlinear dynamical systems evoluting over compact sets are developed. Typically, such systems exhibit “complicated dynamics,” i.e., have nontrivial recurrence. The controllers, which use small perturbations of the nominal dynamics as input actuators, are based on modeling the tracking error as a linear dynamically ...

Chromosomal translocation (CT) is of enormous clinical interest because this disorder is associated with various major solid tumors and leukemia. A tumor-specific fusion gene event may occur when a translocation joins two separate genes. Currently, various CT databases provide information about fusion genes and their genomic elements. However, no database of the roles of fusion genes, in terms ...

texture image analysis is one of the most important working realms of imageprocessing in medical sciences and industry. up to present, different approacheshave been proposed for segmentation of texture images. in this paper, we offeredunsupervised texture image segmentation based on markov random field (mrf)model. first, we used gabor filter with different parameters’ (frequency,orientation) va...

This paper is concerned about optimal supply levels for a public transport route within an activity-based simulation framework. In a joint optimization of bus headway and fare, we simulate the interaction between users — who choose mode and departure time according to their activities, timetabling and convenience of the public transport service — and a public transport service provider. Differe...

In proof-of-payment transit systems, passengers are legally required to purchase tickets before entering but are not physically forced to do so. Instead, patrol units move about the transit system, inspecting the tickets of passengers, who face fines if caught fare evading. The deterrence of such fines depends on the unpredictability and effectiveness of the patrols. In this paper, we present T...
