BACKGROUND AND AIMS Jatropha curcas is a drought-resistant tree whose seeds are a good source of oil that can be used for producing biodiesel. A successful crop establishment depends on a rapid and uniform germination of the seed. In this work we aimed to characterize the responses of J. curcas seeds to temperature and water availability, using thermal time and hydrotime analysis, METHODS The...
In [1] a feasible timetable generator stochastic simulation modeling framework for the train scheduling problem was developed to obtain a train timetable which includes train arrival and departure times at all visited stations and calculated average train travel time for all trains in the system. In this study, the framework is integrated with a genetic algorithm (GA) in order to get an optimal...
The berth-allocation problem (BAP) aims to optimally schedule and assign vessels to berthing areas along a quay. The vessels arrive at the port over a period of time and normally request service and departure within a time window. These time windows are usually determined through contractual agreements between the port operator and the carrier, in terms of time of departure after the vessel’s a...
Most songbird migrants travel between their breeding areas and wintering grounds by a series of nocturnal flights. The exact nocturnal departure time for these flights varies considerably between individuals even of the same species. Although the basic circannual and circadian rhythms of songbirds, their adaptation to migration, and the factors influencing the birds' day-to-day departure decisi...
Driver behavior under congestion pricing is analyzed in this study to evaluate the effects of alternative congestion pricing schemes. The analysis, which is based on stated-preference survey results, focuses on time allocation, departure time choice and route choice when a congestion pricing scheme is implemented on a toll road. A unique feature of the model system of this study is that departu...

Traffic flow is modeled by a conservation law describing the density of cars. It is assumed that each driver chooses his own departure time in order to minimize the sum of a departure and an arrival cost. There are N groups of drivers, The i-th group consists of κi drivers, sharing the same departure and arrival costs φi(t), ψi(t). For any given population sizes κ1, . . . , κn, we prove the exi...
