We explore the phase diagram of the O(n) loop model on the square lattice in the (x,n) plane, where x is the weight of a lattice edge covered by a loop. These results are based on transfer-matrix calculations and finite-size scaling. We express the correlation length associated with the staggered loop density in the transfer-matrix eigenvalues. The finite-size data for this correlation length, ...

DEFINITION During the last decade, the proliferation of location-aware devices, such as GPS and smartphones, has given rise to the collection of huge amounts of moving object data in the form of finite sequences of time-stamped geographical locations. These sequences of space-time points encode (a sample of) the trajectories of moving objects. The location of the moving objects is unknown betwe...

In recent years, with the continuous development of significant data industrialization, trajectory data have more and more critical analytical value for urban construction and environmental monitoring. However, the trajectory contains a lot of personal privacy, and rashly publishing trajectory data set will cause serious privacy leakage risk. At present, the privacy protection of trajectory dat...

At least two control points must be available in order to determine the position and orientation of a total station (TS). This paper analyses optimum horizontal location of TS with respect to the control points and gives an answer to question “What is the best location of total station with respect to the control points if the goal is to determine the coordinates of TS and detail points as prec...

We study six months of human mobility data, including WiFi and GPS traces recorded with high temporal resolution, and find that time series of WiFi scans contain a strong latent location signal. In fact, due to inherent stability and low entropy of human mobility, it is possible to assign location to WiFi access points based on a very small number of GPS samples and then use these access points...

in this study, a numerical model was developed to investigate the two-dimensional heat transfer in a homogenous finite cylinder to predict the local temperature and sterilizing value during caviar pasteurization. a fixed grid finite difference method was used in the solution of heat transfer equations according to crank-nicolson’s scheme. the model was validated by comparison of the experimenta...
