The rapid global migration of people towards urban areas is multiplying the traffic volume on urban road networks. As a result these networks are rapidly growing in size, in which different sub-networks exhibit distinctive traffic flow patterns. In this paper, we propose a scalable framework for traffic congestion-based spatial partitioning of large urban road networks. It aims to identify diff...

We numerically investigate a second harmonic generation (SHG) in z-cut lithium niobate on insulator (LNOI) waveguide based type-I mode phase matching (MPM) between two fundamental modes. A overlap factor that is close to unity achieved and the normalized SHG efficiency reaches up 72.1% W−1cm−2 at telecommunication band, together with large spectral tunability of 2.5 nm/K. Moreover, bandwidth ab...

Recursive spectral bisection (RSB) is a heuristic technique for finding a minimum cut graph bisection. To use this method the second eigenvector of the Laplacian of the graph is computed and from it a bisection is obtained. The most common method is to use the median of the components of the second eigenvector to induce a bisection. We prove here that this median cut method is optimal in the se...

First, the image is normalized to improve clarity of fingerprint image, and then cut accuracy feature extraction. Then smoothed reduce noise. Based on obvious directionality orientation, trend striations was analyzed by slicing method, based binarization refinement operation carried out eliminate skeleton fingerprint. When detail points are determined relationship between core can be compared d...

The device for applying meliorants is designed the distribution of nutrients, presented in liquid form, sublap space a plane-cutting tillage tool. Distribution carried out by spraying meliorants, which allows you to saturate fertile soil layer with nutrients and substances obtain high yield. Spraying occurs due directional effect compressed air on jet, as result jet breaks up into finely disper...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

in this paper, we study an equivalence relation on the set of fuzzysubgroups of an arbitrary group g and give four equivalent conditions each ofwhich characterizes this relation. we demonstrate that with this equivalencerelation each equivalence class constitutes a lattice under the ordering of fuzzy setinclusion. moreover, we study the behavior of these equivalence classes under theaction of a...
