Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

open access: yesArtificial Organs, EarlyView.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

open access: yesComputer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Semi-regular tessellations

open access: yes, 1973
A semi-regular tessellation is one consisting of regular polygons of the same length of side, with the same ‘behaviour’ at each vertex. By this we mean that the polygons appear in the same order (though different senses are allowed) at each vertex.

Alternating Spatial‐Temporal Optimization for Continuous Collision Detection of Signed Distance Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a fast, robust method for continuous collision detection (CCD) directly between pairs of complex signed distance fields (SDFs). By casting CCD as an alternating spatio‐temporal optimization and driving a small set of smartly sampled surface points along SDF tangent spaces, our approach avoids dense sampling or triangle meshes ...

Automatic Generation of Haptic Aspects for a Polyhedron via its Convex Hull

open access: yes, 1996
This paper describes a new algorithm for automatic generation of haptic aspects of a given polyhedron. Haptic aspects are defined as topological equivalent classes of tactual images in-duced by robotic tactile sensing onto an object's surface.

Regular and semiregular polyhedra

open access: yes, 2023
In this Undergraduate Final Project we present a study of the five regular polyhedra (or Platonic Solids) and the thirteen semi-regular polyhedra (or Archimedean Solids).

Investigating Mixed‐Integer Programming Approaches for the p$$ p $$‐α$$ \alpha $$‐Closest‐Center Problem

open access: yesNetworks, Volume 88, Issue 3, Page 331-353, October 2026.
ABSTRACT In this work, we introduce and study the p$$ p $$‐α$$ \alpha $$‐closest‐center problem (pα$$ p\alpha $$CCP), which is a generalization of the p$$ p $$‐second‐center problem, a recently emerged variant of the classical (discrete) p‐center problem.

Convex Polyhedra with Regular Faces

open access: yes, 1966
An interesting set of geometric figures is composed of the convex polyhedra in Euclidean 3-space whose faces are regular polygons (not necessarily all of the same kind).

Unveiling Float Glass Staining Induced by an Acid‐Cleaning Product

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
ABSTRACT Staining of glass facades is a recurring and significant problem worldwide. This study investigates the causes of staining observed on six laminated float glass samples from four manufacturers (α, β, γ, and δ). Samples from β, γ, and δ were new, whereas those from α (α1, α2, and α3) were taken from a building after service exposure.

Neutrosophic regular semi compactness and connectedness

open access: yes, 2022
<p>In this paper, we introduce the concept of neutrosophic regular semi compactness, neutrosophic regular semi connectedness, neutrosophic regular semi strongly connectedness and neutrosophic regular semi-C5-connectedness in neutrosophic ...
