Robot path planning by integrating improved A* algorithm and DWA algorithm
Journal of Physics: Conference Series, 2023 Abstract Traversing many nodes, low search efficiency, path slanting through obstacles, many path redundancy points, and the inability of dynamic real-time obstacle avoidance are all typical problems of A* algorithm. In this paper, A robot path planning method combining improved A* algorithm and DWA algorithm is proposed.The ratio of the

Angewandte Chemie, EarlyView.While dual‐electrode‐free Zn‐MnO2 batteries offer high voltage, intrinsic safety and simple manufacturing, their efficiency and stability are limited by incompatible Zn and MnO2 redox chemistries. This work introduces a dissimilar electrolyte architecture to decouple Zn and MnO2 reactions, endowing a dual‐electrode‐free and lean‐electrolyte Zn‐MnO2 ...

River monitoring from satellite radar altimetry in the Zambezi River basin [PDF]
, 2012 Satellite radar altimetry can be used to monitor surface water levels from space. While current and past altimetry missions were designed to study oceans, retracking the waveforms returned over land allows data to be retrieved for smaller water bodies or

The radial variation of HI velocity dispersions in dwarfs and spirals [PDF]
, 2015 Gas velocity dispersions provide important diagnostics of the forces counteracting gravity to prevent collapse of the gas. We use the 21 cm line of neutral atomic hydrogen (HI) to study HI velocity dispersion and HI phases as a function of galaxy ...

Bounds on the Automata Size for Presburger Arithmetic
, 2004 Automata provide a decision procedure for Presburger arithmetic. However, until now only crude lower and upper bounds were known on the sizes of the automata produced by this approach. In this paper, we prove an upper bound on the the number of states of

Learning Bilingual Word Representations by Marginalizing Alignments
, 2014 We present a probabilistic model that simultaneously learns alignments and distributed representations for bilingual data. By marginalizing over word alignments the model captures a larger semantic context than prior work relying on hard alignments.
