This paper describes a car traffic control simulation realised in a decentralised way by message propagations: congested nodes (roads intersections) send speed-up or slow-down messages to neighbouring nodes. Different types of journeys have been modelled: regular car journeys, accidents and emergency cars journeys. These journeys have different lengths and speeds, and affect the system differen...

We study the problem of finding multimodal journeys in transportation networks, including unrestricted walking, driving, cycling, and schedule-based public transportation. A natural solution to this problem is to use multicriteria search, but it tends to be slow and to produce too many journeys, several of which are of little value. We propose algorithms to compute a full Pareto set and then sc...

Factors Affecting Cattle during Long-Haul Transport in North America Canadian researchers identified and quantified several factors affecting weight loss (shrink) and animal welfare in cattle during commercial long-haul transport (≥ 249 miles). This study documented current commercial practices in Alberta, Canada through surveys delivered to truck drives (6,152 journeys transporting 290,886 ani...

New technologies and the deployment of mobile and nomadic services are driving the emergence of complex communications networks, that have a highly dynamic behavior. This naturally engenders new route-discovery problems under changing conditions over these networks. In this paper, we use and extend a recently proposed graph theoretic model, which helps capture the evolving characteristic of suc...

In 1921 Sir Berkeley Moynihan invited 28 surgeons to come to Leeds with the intention of forming a club of members 'in practice not associated with teaching hospitals'. In 1909 he had founded a similar club to unite surgeons practising in provincial teaching hospitals and the success of this club encouraged him in the new venture. These two Moynihan foundations may have been the first travellin...

le clezio 's fictional world takes us back to the beauties of nature and makes us contemplate the mysteries of the universe. by creating exaggerated and sometimes surreal sceneries, le clezio seeks to escape from inconveniences of the materialistic world to explore man's identity. obscure conditions, wearriness with the achievements of modern world, le clezio's personages, are en...

OBJECTIVE To measure levels of fine particulate matter in the rear passenger area of cars where smoking does and does not take place during typical real-life car journeys. METHODS Fine particulate matter (PM(2.5)) was used as a marker of secondhand smoke and was measured and logged every minute of each car journey undertaken by smoking and non-smoking study participants. The monitoring instru...
