The analysis of the evolution of the organizational and institutional framework of the urban mobility systems around the world provides the evidence that in the large majority of cities the division between decisions of strategic, tactical or operational character is quite blurred. Very often we see a considerable overlap between the decision levels and today we have the evidence that this is a...

This study proposes new Home Agent architecture and algorithms for real-time mobility management in mobile IP networks. The proposed architecture and algorithms offer a better performance based on the call-to-mobility ratio (CMR) and require less time for the location update and the tunneling compared with the Mobile IP model. These results are very useful and interesting for a realtime context...

The flow of Marxism was one of the most powerful social-political currents of the Pahlavi opposition which, despite the progress of political upheavals and internal splits, reached the threshold of the Islamic Revolution. One of the main reasons for the success of this flow, compared to other rival currents, was the presence of numerous symbols in the context of this adventure. The symbols of t...

Six soil amendments including municipal solid waste compost (MSWC), coal fly ash (CFA), rice husk biochar prepared at 300°C (B300) and 600°C (B600), zerovalent iron (Fe0), and zerovalent manganese (Mn0) were evaluated to determine their ability to reduce mobility of chromium (Cr) in a Cr-spiked soil. The Cr-spiked soil samples were separately incubated with selected amendments at 2 and 5% [weig...

Microscopic oil displacement of water flooding and sweep efficiency of continuous gas injection could be improved by water alternating gas (WAG) injection. The WAG injection process aims to squeeze more oil out of the reservoirs; in this method, water and gas are alternatively injected into the reservoir. Also, availability of hydrocarbon or CO2 gases in the field makes it attractive for gas-ba...

This paper considers optimal social insurance in a dynamic moral hazard economy. The existing literature has focussed on environments in which a planner and a population of agents share the same discount factor. A key finding is that agents are then almost surely immiserated; their welfare is driven to its lowest bound. Such immiseration requires a social commitment to treat (almost) everyone a...

In today’s era of globalization, sustainable mobility is considered as a key factor in the economic growth of any country. With the emergence of open data initiatives, there is tremendous potential to improve mobility. This paper presents findings of a detailed analysis of mobility open data initiatives in nine smart cities – Amsterdam, Barcelona, Chicago, Dublin, Helsinki, London, Manchester, ...

Human mobility is a key factor in spatial disease dynamics and related phenomena. In computational models host mobility is typically modeled by diffusion in space or on metapolulation networks. Alternatively, an effective force of infection across distance has been introduced to capture spatial dispersal implicitly. Both approaches do not account for important aspects of natural human mobility,...
