Global Sensitivity Analysis Applied To Model Inversion Problems: A Contribution To Rail Condition Monitoring, René Schenkendorf, Jörn Groos May 2015

Global Sensitivity Analysis Applied To Model Inversion Problems: A Contribution To Rail Condition Monitoring, René Schenkendorf, Jörn Groos

René Schenkendorf

Rising demands on railroad infrastructure operator by means of profitability and punctuality call for advanced concepts of Prognostics and Health Management. Condition based preventive maintenance aims at strengthening the rail mode of transport through an optimized scheduling of maintenance actions based on the actual and prognosticated infrastructure condition, respectively. When applying model-based algorithms within the framework of Prognostics and Health Management unknown model parameters have to be identified first. Which of these parameters should be known as precisely as possible can be figured out systematically by a sensitivity analysis. A comprehensive global sensitivity analysis, however, might be prohibitive by means …

Game Theory In Transport & Logistic World, Sajjad Khaksari

SAJJAD KHAKSARI

"OV & DP and BRT" some assumptions and a Case Study for studying John Nash "Game Theory" method in logistics and transportation world and that is only a briefly attempt to get familiar with the idea. A thought which asks "Is it possible to model and analyze one of the authenticity of the transport or logistics service request with respect to the Game Theory optimization idea?


Love Is A Two Way Street, William W. Riggs, John Gilderbloom May 2015

Love Is A Two Way Street, William W. Riggs, John Gilderbloom

William W. Riggs

A half a century ago, we were in love with our streets. They were also living things. They were the open-air living room of our society, the conduct for neighborhood play and discussion, the glue of our social fabric. One of the key urban theorists of the 20th century, Jane Jacobs wrote in Fortune Magazine that the street “…works harder than any other part of downtown. It is the nervous system; it communicates the flavor, the feel, the sights. It is the major point of transaction and communication. Users of downtown know very well that downtown needs not fewer streets, …

Utilising Location Based Social Media In Travel Survey Methods: Bringing Twitter Data Into The Play, Alireza Abbasi, Taha Hossein Rashidi, Mojtaba Maghrebi, S. Travis Waller Jan 2015

Utilising Location Based Social Media In Travel Survey Methods: Bringing Twitter Data Into The Play, Alireza Abbasi, Taha Hossein Rashidi, Mojtaba Maghrebi, S. Travis Waller

Alireza Abbasi

A growing body of literature has been devoted to harnessing the crowdsourcing power of social media by extracting knowledge from the huge amounts of information available online. This paper discusses how social media data can be used indirectly and with minimal cost to extract travel attributes such as trip purpose and activity location. As a result, the capacity of Twitter data in complementing other sources of transport related data such as household travel surveys or traffic count data is examined. Further, a detailed discussion is provided on how short term travellers, such as tourists, can be identified using Twitter data …
