This paper examines the benefits of Michaelis-Menten model reduction techniques in stochastic tau-leaping simulations. Results show that although the conditions for the validity of the reductions for tau-leaping remain the same as those for the stochastic simulation algorithm (SSA), the reductions result in a substantial speed-up for tau-leaping under a different range of conditions than they d...

In the present study, hyperspectral imaging and remote sensing of fluorescence were integrated to monitor nitrogen content in leaves drip-irrigated cotton at different growth periods northern Xinjiang, China. Based on spectrum chlorophyll parameters obtained through shuffled frog-leaping algorithm (SFLA), successive projection (SPA), grey relational analysis (GRA), competitive adaptive reweight...

Reliable fault diagnosis of the rolling element bearings highly relies on correct extraction fault-related features from vibration signals in time-frequency analysis. However, considering nonlinear, nonstationary characteristics signals, hidden heavy noise has become a challenging task. Variable mode decomposition (VMD) is an adaptive, completely nonrecursive method variation and signal process...

In pipeline transportation of slurry, the existing calculation models of critical deposition velocity face the problem of different model forms only suitable for specific conditions. To address this problem, this paper uses improved “shuffled frog leaping algorithm” (SFLA) to optimize the parameters of the computational model in order to calculate critical deposition velocity. This has been fou...

The construction of low-cost nanogrids could help speed up the electrification rate in remote communities sub-Saharan Africa. One challenges nanogrid design for these is uncertainty future load demand profiles impacting cabling topology. We propose two new wiring approaches radial direct current power distribution systems. first one a modified minimum spanning tree (MST) algorithm and second an...

Path planning evaluates and identifies an obstacle free path for a wheeled mobile robot (WMR) to traverse within its workspace. It emphasizes metric like, start goal coordinate, static or dynamic workspace, obstacles, computational time local minimum problem. play significant role toward WMR effective it workspace like industrial, military, hospital, school office. In this is optimal method inc...

The Jiles-Atherton model is key to researching the hysteresis loop. focus of scholars across various countries has always been parameter identification model. This paper on Levy whale optimization algorithm (LWOA), based (WOA), proposes overcome disadvantage that WOA tends involve local optimum. recommended uses flight strategy instead encircling prey policy since former improves global search....

This paper introduces a new acceleration technique for ray casting type volume rendering called IsoRegion Leaping. A factorization of the sample composition equation leads to our new algorithm which is based on homogeneity inside a volume. We create an IsoRegion data structure to help identifying homogeneous voxel cubes, which is independent of the viewing parameters and shading conditions, thu...
