1. 1. Dynamic Queries

   Författare :Christopher Ahlberg; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Dynamic queries is an approach to database querying, information exploration, and information retrieval. Building on principles of direct manipulation, dynamic queries utilizes visualizations and graphical query devices to allow users to visually explore, browse, and query large datasets. LÄS MER

3. 2. The high dynamic range imaging pipeline : Tone-mapping, distribution, and single-exposure reconstruction

   Författare :Gabriel Eilertsen; Jonas Unger; Rafał Mantiuk.; Anders Ynnerman; Erik Reinhard; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high dynamic range imaging; tone-mapping; video tone-mapping; HDR video encoding; HDR image reconstruction; inverse tone-mapping; machine learning; deep learning;

   Sammanfattning : Techniques for high dynamic range (HDR) imaging make it possible to capture and store an increased range of luminances and colors as compared to what can be achieved with a conventional camera. This high amount of image information can be used in a wide range of applications, such as HDR displays, image-based lighting, tone-mapping, computer vision, and post-processing operations. LÄS MER

4. 3. Extending dynamic vegetation models to simulate range shifts

   Författare :Deborah Zani; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic vegetation model; range shift; migration; paleovegetation;

   Sammanfattning : In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). LÄS MER

5. 4. Towards Joint Super-Resolution and High Dynamic Range Image Reconstruction

   Författare :Tomas Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Super-resolution; Dynamic range; Human visual system; Inverse problem; Image reconstruction; Spatial alignment; Photometric alignment; Digital camera system;

   Sammanfattning : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

7. 5. Discovery-Oriented Screening of Dynamic Systems: Combinatorial and Synthetic Applications

   Författare :Marcus Angelin; Olof Ramström; Stefan Kubik; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical education; crystallization; dynamic combinatorial chemistry; dynamic combinatorial resolution; dynamic system; enzyme catalysis; isoindolinone; lipase; nitroalcohol; nitroaldol reaction; phthalide; reversible; secondary alcohol; systems chemistry; tandem reaction; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi;

   Sammanfattning : This thesis is divided into six parts, all centered around the development of dynamic (i.e., reversibly interacting) systems of molecules and their applications in dynamic combinatorial chemistry (DCC) and organic synthesis. LÄS MER
