Simultaneous localization and mapping (SLAM) is crucial challenging for autonomous underwater vehicle (AUV) navigation in complex uncertain ocean environments. However, inaccurate time-varying observation noise parameters may lead to filtering divergence poor accuracy. In addition, particles are easily trapped local extrema during the resampling, which state estimation. this paper, we propose a...

We present preliminary results from simulated large sky coverage (∼100 square degrees) Sunyaev-Zeldovich effect (SZE) cluster surveys using the cosmological adaptive mesh refinement N-body/hydro code Enzo. We have generated simulated light cones to match the resolution and sensitivity of current and future SZE instruments. These simulations are the most advanced calculations of their kind. The ...

Experts of chance discovery have faced a new problem, where the previous methods fail to visualize a latent structure behind observation. Invisible events play an important role in the dynamics of visible events. They are called “dark events”. This paper proposes a new method named “human-interactive annealing” for revealing a latent structure and understanding dark events and illustrates pract...

It is a long time that the Simulated Annealing (SA) procedure is introduced as a model-free optimization for solving NP-hard problems. Improvements from the standard SA in the recent decade mostly concentrate on combining its original algorithm with some heuristic methods. These modifications are rarely happened to the initial condition selection methods from which the annealing schedules start...

A device for electrostatic separation of triboelectrically charged plastic particles is modeled and optimized. Electric field in the system is solved numerically by a fully adaptive higher-order finite element method. The movement of particles in the device is determined by an adaptive Runge-Kutta-Fehlberg method. The shape optimization of the electrodes is carried out by a technique based on g...

We present a Tabu Search (TS) method that employs a simple version of ejection chains for coloring graphs. The procedure is tested on a set of benchmark problems. Empirical results indicate that the proposed TS implementation outperforms other metaheuristic methods, including Simulated Annealing, a previous version of Tabu Search and a recent implementation of a Greedy Randomized Adaptive Searc...
