DESIGN MODELLING AND ANALYSIS OF A WIND TURBINE BLADE SUPPORT SYSTEM

Journal of Industrial Design and Engineering Graphics, 2017
Wind turbines and green energy is of high interest nowadays and the size of the powerplants keeps getting bigger and bigger. The forces that arise as the blades increase in size have the magnitude to deform the profiles.

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Fused Collapsing for Wide BVH Construction

Computer Graphics Forum, EarlyView.
Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...

UBVH: Unified Bounding Volume and Scene Geometry Representation for Ray Tracing

Computer Graphics Forum, EarlyView.
Abstract Bounding volume hierarchies (BVHs) are currently the most common data structure used to accelerate ray tracing. The existing BVH methods distinguish between the bounding volume representation associated with the interior BVH nodes and the scene geometry representation associated with leaf nodes.

Mitogenome structure and phylogenomics of the order Thoreales (Nemaliophycidae, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract Organelle genomes offer a powerful tool for red algal evolutionary studies. Although the number of Rhodophyta genomes has increased substantially over the past 2 decades, only two mitochondrial genomes have been reported for the red algal order Thoreales.

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, Volume 101, Issue 4, Page 1735-1759, August 2026.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy
