Classification and equivalences of noncommutative tori and quantum lens spaces
, 2012 In noncommutative geometry, one studies abstract spaces through their, possibly noncommutative, algebras of continuous functions. Through these function algebras, and certain operators interacting with them, one can derive much geometrical information of

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics
Advanced Engineering Materials, EarlyView.Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

Computational information geometry and its applications
, 2005 Digitization is the main feature of modern Information Science. Conjoining the digits and the coordinates, the relation between Information Science and high-dimensional space is consanguineous, and the information issues are transformed to the geometry ...

Angle and distance geometry problems
, 1991 Distance geometry problems (DGPs) are concerned with the construction of structures given partial information about distances between vertices. I present a generalisation which I call the angle and distance geometry problem (ADGP), in which partial angle

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V
Advanced Engineering Materials, EarlyView.Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Research on the use of dynamic geometry software: implications for the classroom
, 2005 This review examines research that has investigated the use of dynamic geometry software (DGS) in the teaching and learning of mathematics. The research is categorised under three main headings: interacting with the software, designing teaching ...

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Elements of the visualisation process within a dynamic geometry environment
, 1996 The advent of powerful computer graphic packages has coincided with renewed interest in all forms of visual representation in mathematics. As a result, we need to be clear about what we mean by the visual processing necessary to solve mathematical ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
