An Efficient Index Building Algorithm for Selection of Aggregator Nodes in Wireless Sensor Networks

International Journal of Distributed Sensor Networks, 2014
In wireless sensor networks (WSNs), aggregator nodes perform the data aggregation process. Thus, careful selection of the aggregator nodes is needed to reduce network traffic in data aggregation process and prolong overall lifetime of the network.

Degradation Mechanism of Phosphate‐Based Li‐NASICON Conductors in Alkaline Environment

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The presence of water in the cathode of a Li‐air battery shifts reactions to produce LiOH, creating a corrosive, alkaline environment. This study investigates the alkaline stability of the common Li‐NASICON solid‐state conductor chemistries through a systematic experimental study combined with computational modeling to understand the degradation ...

Design for Copying Grouser and Bionic Convex Hull Patterns on Track Surfaces of Crawler Combine Harvesters

Agriculture
In the rainy season, which often has uncertain rainfall, crawler combine harvesters have difficulty traversing wet and soft rice fields. A large amount of clay is often accumulated on the track surfaces, resulting in frequent slipping and sinking, which ...

Confining Surface Oxygen Redox in Double Perovskites for Enhanced Oxygen Evolution Reaction Activity and Stability

Advanced Energy Materials, EarlyView.
The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).

A Fast and Robust Support Vector Machine With Anti-Noise Convex Hull and its Application in Large-Scale ncRNA Data Classification

IEEE Access, 2019
Support vector machine (SVM) achieves successful classification performance with the application in non-coding RNA (ncRNA) data. With the rapid increase of the species and sizes of ncRNA sequences, several fast SVM methods based on data distribution and ...

Alpha-Concave Hull, a Generalization of Convex Hull [PDF]

arXiv, 2013
Bounding hull, such as convex hull, concave hull, alpha shapes etc. has vast applications in different areas especially in computational geometry. Alpha shape and concave hull are generalizations of convex hull. Unlike the convex hull, they construct non-convex enclosure on a set of points.
