چکیده

Consider the region L := {(x, y) : 0 ≤ y ≤ C log(1 + x), x > 0} for a constant C > 0. We study the percolation and coverage properties of this region. For the percolation properties we place a Poisson point process of intensity λ on the region L. At each point of the process we centre a box of a random side length ρ. In case ρ ≤ R for some fixed R > 0 we study the critical intensity λc of percolation. For the coverage properties we place a Poisson point process of intensity λ on the entire half space R+ ×R and associated with each Poisson point we place a box of a random side length ρ. Depending on the tail behaviour of the random variable ρ we exhibit a phase transition in the intensity for the eventual coverage of the region L.

Propagation Models and Fitting Them for the Boolean Random Sets

In order to study the relationship between random Boolean sets and some explanatory variables, this paper introduces a Propagation model. This model can be applied when corresponding Poisson process of the Boolean model is related to explanatory variables and the random grains are not affected by these variables. An approximation for the likelihood is used to find pseudo-maximum likelihood esti...

محاسبه شدت جزیره حرارتی بر اساس هندسه شهری موردمطالعه: محله کوچه‌باغ شهر تبریز

Urban climate is strongly influenced by the processes of urban work and life. Expansion of cities and consequently increased human constructions causes to changes in urban climate. The rising temperature of cities rather than the surroundings is one of the effects linked to direct human intervention. Building heating, air pollution and the use of inappropriate materials in the flooring streets...

Dynamic Stability of Moderately Thick Composite Laminated Skew Plates using Finite Strip Method

The dynamic instability regions of composite laminated skew flat plates subjected to uniform in-plane axial end-loading are investigated. The in-plane loading is assumed as a combination of a time-invariant component and a harmonic time-varying component uniformly distributed along two opposite panel ends’ width. In case of some loading frequency-amplitude pair-conditions, the model is subjecte...

Comparison of parametric and fuzzy analytic hierarchy process in land evaluation (Case study: Varamin region)

In last decades, the skillful planning of land resources has become a major issue for rural development. The development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. Fuzzy logic is preferred to Boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can the...
