Redesigned crinkle washer for piezoelectric energy generation

Frontiers in Mechanical Engineering
Structures are used for piezoelectric energy harvesters as a way of redirecting the path of an inputted force so that the piezoelectric element can better convert the mechanical energy to electrical energy.

Neural Network-Based Prediction of Wave Pressure Distribution on Hyperbolic Paraboloid Surfaces

Journal of Marine Science and Engineering
Recent studies have demonstrated the potential of hyperbolic paraboloid (hypar), a doubly curved geometry, in coastal engineering applications. Predicting pressure distribution, critical for subsequent finite element analysis, on such novel three ...

Optimal Segmentation of Glass Shell Structures

Challenging Glass Conference Proceedings, 2016
Monolithic glass shells can be constructed in limited sizes. Segmented shells allow coverage of larger spans. Three shell systems - spherical dome, cylindrical roof and hyperbolic paraboloid were segmented using four different curved glass segment shapes

HPG-Tree: An Enhanced B⁺-Tree for Spatial Indexing

IEEE Access
In modern applications such as geographic information systems, game development, and image processing, the demand for efficient two-dimensional spatial indexing is rising exponentially. Traditional approaches like R-tree can suffer from excessive overlap

DESIGN AND EVALUATION OF A HORSE SADDLE USING CAD SOFTWARE

Journal of Industrial Design and Engineering Graphics
The pressure on a horse's back can affect their performance during the equestrian competition. A better pressure distribution on the surface of the horse's back can be obtained using a custom saddle, considering the rider's weight and back anatomy.
