1. 1. Digital Geometry and Khalimsky Spaces

   Författare :Erik Melin; Christer Kiselman; Gunilla Borgefors; Mikael Passare; Jean Serra; Uppsala universitet; []
   Nyckelord :Applied mathematics; Khalimsky topology; digital geometry; digital topology; Alexandrov space; digital surface; digital curve; digital manifold; continuous extension; smallest-neighborhood space; image processing; Tillämpad matematik;

   Sammanfattning : Digital geometry is the geometry of digital images. Compared to Euclid’s geometry, which has been studied for more than two thousand years, this field is very young.Efim Khalimsky’s topology on the integers, invented in the 1970s, is a digital counterpart of the Euclidean topology on the real line.

3. 2. Global Shape Description of Digital Objects

   Författare :Ola Weistrand; Christer Kiselman; Gunilla Borgefors; Örjan Smedby; Michael Floater; Uppsala universitet; []
   Nyckelord :Applied mathematics; shape description; shape approximation; surface parameterization; digital object; spherical harmonics; digital surface; digital image; Tillämpad matematik;

   Sammanfattning : New methods for global shape description of three-dimensional digital objects are presented. The shape of an object is first represented by a digital surface where the faces are either triangles or quadrilaterals. LÄS MER

4. 3. Digital dentistry : studies on the trueness and precision of additive manufacturing and intraoral scanning

   Författare :Michael Braian; Malmö universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Artificial designs and features usually control production workflowsin the industry. The operator has the freedom to adapt designs toachieve the desired function; when the operator is satisfied, massproduction of the two objects is possible. LÄS MER

5. 4. Electronic and Molecular Surface Structures of Dye-Sensitized TiO2 Interfaces

   Författare :Maria Hahlin; Håkan Rensmo; Hans Siegbahn; Anders Sandell; Mats Göthelid; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoelectron spectroscopy; Electron spectroscopy; Solar Cells; Dye; TiO2; Surface; Interface; Electronic structure; Molecular surface structure; coadsorbent; Physics; Fysik; Fysik; Physics;

   Sammanfattning : The dye-sensitized solar cell is a promising solar cell technology. In these systems the key process for light to electricity conversion is molecular in nature and is initiated in dye molecules adsorbed at a semiconducting surface. LÄS MER

7. 5. Human-centric process planningfor Plug & Produce : Digital threads connecting product design withautomated manufacturing

   Författare :Anders Nilsson; Fredrik Danielsson; Kerstin Johansen; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug Produce; Digital Threads; Industrial Manufacturing; Process Planning; Multiagentsystem; Processplanering; Plug Produce; Digitala kedjor; Industriell Tillverkning; Flexibel Automation; Production Technology; Produktionsteknik;

   Sammanfattning : Adaptations to a fluctuating market and intensified customer demands for unique products are a challenge for manufacturers. Manual manufacturing is still the most flexible, nevertheless, automation ensures stable quality, minimizes wear and tear of the operators, and contributes to a safer and better working environment as the distance between the operator and the process can be increased and screened off.
