Integrating people and place: A density-based measure for assessing accessibility to opportunities

Horner, Mark; Downs, Joni - In: The Journal of Transport and Land Use 7 (2014) 2, pp. 23-40

objects may include people, animals, or vehicles. Time geography remains a key theoretical framework for understanding mobile … has blended time geography and kernel density estimation in order to delineate the probable locations of mobile objects in … assessing mobile objects' potential for interacting with opportunity locations. As accessibility measures have also garnered …

Covering moving points with anchored disks

Bautista-Santiago, C.; Díaz-Báñez, J.M.; … - In: European Journal of Operational Research 216 (2012) 2, pp. 278-285

Consider a set of mobile clients represented by n points in the plane moving at constant speed along n different straight lines. We study the problem of covering all mobile clients using a set of k disks centered at k fixed centers. Each disk exists only at one instant and while it does, covers...

Volatile jam and flow fluctuation in counter flow of slender particles

Ito, Satoru; Nagatani, Takashi; Saegusa, Tatsuhiko - In: Physica A: Statistical Mechanics and its Applications 373 (2007) C, pp. 672-682

We study the counter flow of slender particles on square lattice under periodic boundaries. Two types of particles going to the right and to the left are taken into account, where the size of right particles is larger than that of left particles. The counter flow of slender particles with...

Jamming transition in counter flow of slender particles on square lattice

Nagai, Ryoichi; Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 366 (2006) C, pp. 503-512

We study the counter flow of slender particles on square lattice under a periodic boundary where each particle consists of 1×n sites. Two types of particles going to the right and to the left are taken into account. The characteristics of counter flow are clarified numerically. The jamming...

Many epidemiological studies involve analysis of clusters of diseases to infer locations of environmental hazards that could be responsible for the disease. This approach is however only suitable for sedentary populations or diseases with small latency periods. For migratory populations and...
