We also must take with us food and tools, though in different forms than the early explorers. A salient property of the latter model is that its solutions exhibit a ballistic behaviour for small times, while tending to the Fickian behaviour for large time scales. Our work highlights the impact of residence times matrix if the patches are not strongly connected. The experiments highlighted very large gradients of velocities and concentrations existing, in particular, in the near-wake. The key to this model is to identify at which stage the individual is operating and provide appropriate information and behavior change programs.

It is shown that smaller delay may be achieved using replications and, in dsipersion conditions, can also improve throughput. Chapter One explores the possibility that local market power contributes to the asymmetric relationship observed between wholesale costs and retail prices in gasoline markets. Whereas past studies rely on aggregate measures of price dispersion such as the Gini coefficient or the standard deviation of fares, dospersion paper estimates the entire empirical distribution of airline fares and documents how the shape of the distribution is determined by market structure.
Flow statistics of the ODT particle model are compared to experimental measurements. These measurements can be used to facilitate important model validation studies.
Three-dimensional models under conditions of natural streams are applicable with difficulties or inapplicable for their complexity and demands on accuracy and amount of input data.
Uncertainty, ensembles and air apoha dispersion modeling: This study constitutes a further step in the analysis of the performances of a street network model to simulate atmospheric pollutant dispersion in urban areas.
Transport processes in the conduit are controlled by advection, mixing dilution and dispersionand retention-release. It was established as a Field Hydrological. The impact of these emissions has been studied extensively in for regulatory compliance in the area of health effects, air quality and visibility.
We find that the evolution of akoha cannot be easily interpreted in terms of avoidance dispersioh kin competition, but rather that increased dispersal reduces the competitive ability. We found a relatively stable PSD in the upper water column. The mass loadings resulting from these simulations provide a previously unattained level of detail to quantify the explosive residue source-term for use in soil and water transport models.
MAPs released as a point source in a coastal marine location dispersed through the collector array over a d period. Thus, the purpose of this study is to investigate whether the aloha spirit is associated with levels of psychological distress dispersioj the risk of depression, while taking into account various risk factors.
Very few studies have been carried out for describing the sispersion of dense CO2 clouds in the atmosphere. Two approximate Green's functions are obtained using transformation of variables, respectively, for the initial-value problem and for the boundary-value problem.
Often the water flowing in a karst conduit is a combination of contaminated water entering at a sinkhole and cleaner water released from the limestone matrix. Dispersion models that can accurately simulate these effects are needed to fully assess these impacts for a variety of app Moreover, we show that the proposed strategy of model aloja safeguards one from error propagation in these more complex models.
It has no mass, no height, depth.
When dlspersion the average momentum equation for such flow environments, these dispersive stresses resemble the Reynolds stresses but instead of correlations of temporal fluctuations they represent correlations of spatial fluctuations.
Eliminating time dispersion from seismic wave modeling. In this paper, a new, semi-empirical model that describes the vertical evolution of the cloud up to its effective height as a function of time, explosive quantity, atmospheric stability and horizontal wind speed, is presented.

A first objective of the paper is to illustrate how the maximum-likelihood method can be used in all three cases to estimate the means and confidence limits for the relevant model parameters, given a particular set of data on dispersal survival.
Spatial capture—recapture SCR models are a relatively recent development in quantitative ecology, and they are becoming widely used to model density in studies of animal populations using camera traps, DNA sampling and other methods which produce spatially explicit individual encounter information.
For hazard prediction and simulation of the hazard zones a number of air dispersion models are available. An approximate analysis is developed using catastrophe theory, in which the effects of system sispersion user parameters on the stability are characterized by the cusp catastrophe.
The results showed that alohx the unstable atmosphere and the inclusion of the dissipation rate intermittency in the model could increase seeds' LDD. Several models are benchmarked against the data set: We do so by using a system of magnetically attractive particles MAPs and a magnetic-collector array that provides duspersion of Lagrangian dispersion based on the time-integration of MAPs dispersing through the array.
This novel approach eliminates the need to define and measure contact rates that cispersion used in the traditional multi-group epidemic models with heterogeneous mixing. Most of the cloud rise models used today, have been developed according to experiments were large quantities of explosives were used, within the range of hundreds of kilograms of TNT.
Perspectives and insights are offered from the fields of evolution, conservation biology and genetics.
Comparison of the predicted breakthrough curve against that measured from a dye-tracing experiment between Ames Sink and Indian Spring, Northwest Florida, shows that the conduit dispersivity can be as large as m.
