The large-scale tropospheric circulation can play a controlling role in the accumulation and ventilation of air pollutants. It thus impacts air quality in large urban areas. This paper investigates the statistical relations between the dynamical indices related to circulation in the troposphere and visibility as a surrogate for air pollution in the urban area of Tehran for the climatological pe...
We consider the fundamental Mutual Visibility problem for a set of n identical autonomous point robots (n is not known to the robots) that operate following Look-Compute-Move cycles starting from arbitrary distinct positions in the Euclidean plane under obstructed visibility – a robot ri can see robot rj , rj 6= ri, if and only if there is no other robot in the line segment joining their positi...
Coastal ecosystems and the livelihoods they support are threatened by stressors acting at global and local scales. Here we used the data produced by the Caribbean Coastal Marine Productivity program (CARICOMP), the longest, largest monitoring program in the wider Caribbean, to evidence local-scale (decreases in water quality) and global-scale (increases in temperature) stressors across the basi...
We analyze visibility from static sensors in a dynamic scene with moving obstacles (people). Such analysis is considered in a probabilistic sense in the context of multiple sensors, so that visibility from even one sensor might be sufficient. Additionally, we analyze worst-case scenarios for high-security areas where targets are non-cooperative. Such visibility analysis provides important perfo...
This paper investigates the trajectory generation problem for an advanced driver assistance system that could sense the driving state of the vehicle, so that a collision free trajectory can be generated safely. Specifically, the problem of trajectory generation is solved for the safety assessment of the driving state and to manipulate the vehicle in order to avoid any possible collisions. The v...
We propose a method for multi-objective optimization of tree arrangement in urban open space. The Pareto solutions the consider trade-offs between thermal radiant environment, green visibility, and sky visibility. result captures reasonably shows that even when amount trees is same, can have nonnegligible impacts on mean temperature, Furthermore, we show procedures utilizing solutions, which su...
We present an experiment where the quantum coherence in the edge states of the integer quantum Hall regime is tuned with a decoupling gate. The coherence length is determined by measuring the visibility of quantum interferences in a Mach-Zehnder interferometer as a function of temperature, in the quantum Hall regime at a filling factor 2. The temperature dependence of the coherence length can b...
In this paper, we survey kinetic visibility problems. Unlike the research in traditional visibility problems, the researchers have also taken moving objects into consideration. These problems have been addressed from different practical aspects, such as computational graphics and robotic design. Over the years, some general combinatorial results of the visibility graph have been shown. Leveragi...
