This paper argues for a “human-centered” approach to knowledge discovery from movement data through the use of visualization and mapping. As becomes more available diverse in dime...

In design and analysis, standard references assume the pedestrian flow as unidirectional. In reality however, pedestrian flow is usually bi-directional. The main question pursued in this paper is that whether the main characteristics of pedestrian flow the same under uni- and bi-directional conditions. In order to achieve this goal, effect of bi-directional stream is inv...

I work in geometric group theory, which is the study of groups via the metric spaces on which they act. I use combinatorial, geometric, and topological tools to study the coarse geometry of infinite discrete groups. Coarse geometry is the natural setting for studying discrete groups, since their metric geometry is only well-defined up to bounded distortion. Gromov [65] revolutionized the field ...

Debris flows are typically modelled as a single homogeneous surge due to lack of data support more complex model development and time funding for the practitioner communities they aim support. Coarse debris characterized by coarse front, followed muddy slurry, that is then hyperconcentrated flow phase with lesser sediment concentrations. Presented herein modelling hazard assessment Hummingbird ...

Efficient solution of the Navier-Stokes equations in complex domains is dependent upon the availability of fast solvers for sparse linear systems. For unsteady incompressible flows, the pressure operator is the leading contributor to stiffness. as the characteristic propagation speed is infinite. In the context of operator splitting formulations, it is the pressure solve which is the most compu...

Gathering information on how invasive species utilize the habitat is important, in order to better aim actions to reduce their negative impact. We studied habitat use and selection of 55 GPS-marked raccoon dogs (30 males, 25 females) at their invasion front in Northern Sweden, with particular focus on differences between males and females, between movement states, and between seasons and times ...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

The paper presents a Bézier triangle based isogeometric shape optimization method. Bézier triangles are used to represent both the geometry and physical fields. For a given physical domain defined by B-spline boundary, a coarse Bézier triangular parameterization is automatically generated. This coarse mesh is used to maintain parameterization quality and move mesh by solving a pseudo linear ela...
