1. 1. Supporting evidence-based design using lighting simulations : A framework for lighting simulation of visual comfort in building design

   Författare :Anahita Davoodi; Myriam Aries; Peter Johansson; Thorbjörn Laike; John Mardaljevic; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lighting quality; visual comfort; lighting simulation; evidence-based design; field study; post-occupancy evaluation; Ljuskvalitet; visuell komfort; ljussimulering; evidensbaserad design; fältstudie; brukarutvärderingar;

   Sammanfattning : This research aims to integrate lighting simulation into the evidence-based design process for achieving improved lighting outcomes in built environments with a particular emphasis on visual comfort analysis in office settings. The objectives of the study include 1) understanding the current usage of lighting simulation tools, learning designers’ experiences' and needs, 2) providing a conceptual framework to integrate the use of lighting simulation in the evidence-based design (EBD) process, 3) testing the usage of the conceptual framework (named EBD-SIM) through two field studies.

3. 2. Towards Automatic Quantification of Immunohistochemistry Using Colour Image Analysis

   Författare :Petter Ranefall; Ewert Bengtsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computerized Image Analysis; Datoriserad bildanalys;

   Sammanfattning : Quantification of the proportions of specifically stained regions in images is of significant interest in a growing number of biomedical applications. These applications includes histology and cytology where quantification of various stainings performed on histological tissue sections, smears, imprints etc. is of utmost importance. LÄS MER

4. 3. Face Recognition : A Single View Based HMM Approach

   Författare :Hung Son Le; Haibo Li; Josef Bigun; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; face recognition; pattern recognition; computer vision; HMM; Hidden Markov Models; contrast enhancement; pyramid fusion; image processing; Computer science; Datavetenskap;

   Sammanfattning : This dissertation addresses the challenges of giving computers the ability of doing face recognition, i.e. discriminate between different faces. Face recognition systems are commonly trained with a database of face images, becoming “familiar” with the given faces. LÄS MER

5. 4. Study of GaN Based Nanostructures and Hybrids

   Författare :Mathias Forsberg; Galia Pozina; Ching-Lien Hsiao; Kevin P. O'Donnell; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sputtering; Forster; Semiconductor; Nitride; GaN; Hybrid; Nanorods; Nanostructure; Thin film; Förstoffning; Sputtring; Förster; Halvledare; Nitrid; GaN; Hybrider; Nanostavar; Nanostrukturer; tunnfilmer;

   Sammanfattning : GaN and its alloys with Al and In belong to the group III nitride semiconductors and are today the materials of choice for efficient white light emitting diodes (LEDs) enabling energy saving solid state lighting. Currently, there is a great interest in the development of novel inexpensive techniques to fabricate hybrid LEDs combining high quality III-N quantum well (QW) structures with inexpensive colloidal nanoparticles or conjugated polymers.

7. 5. Incident Light Fields

   Författare :Jonas Unger; Anders Ynnerman; Reiner Lenz; Alan Chalmers; Linköpings universitet; []
   Nyckelord :Computer Graphics; Image Based Lighting; Photorealistic Rendering; Light Fields; High Dynamic Range Imaging; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Image based lighting, (IBL), is a computer graphics technique for creating photorealistic renderings of synthetic objects such that they can be placed into real world scenes. IBL has been widely recognized and is today used in commercial production pipelines. However, the current techniques only use illumination captured at a single point in space. LÄS MER
