2. 1. Microsystems Technology for Underwater Vehicle Applications

   Author : Jonas Jonsson; Greger Thornell; Hugo Nguyen; Johan Köhler; Uppsala universitet; []
   Keywords : Aquatic; Submersible; Underwater; Micro; Miniaturized; Sonar; Sidescan; Topography; Laser; Diffractive; Optics; Sampler; Particle; Microorganism; Acoustic; Enriching; Conductivity; Temperature; Depth; CTD; Flow; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Abstract : The aim of this thesis work has been to investigate how miniaturization, such as microsystems technology, can potentially increase the scientific throughput in exploration of hard-to-reach underwater environments, such as the subglacial lakes of Antarctica, or other challenging environments, including cave systems and wrecks. A number of instruments and subsystems applicable to miniature submersibles have been developed and studied, and their potential to provide a high functionality density for size-restricted exploration platforms has been assessed.

   Abstract : The decentralization of chemical sensing to attain environmental-related information is today highly desirable to increase the knowledge on biological or geological events as well as effluents. The current state of the field moves toward submersible probes; chemical sensors implemented into submersible devices for quantifying analytes over extended times. READ MORE

6. 4. Designing for Extremes

   Author : Olga Bannova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Architect; Human Factors; Engineering; Engineer; Multidisciplinary and Trans-disciplinary Design and Planning.; Extreme environments; Architecture; Design Planning;

   Abstract : The starting point of this research is based on personal experience in research and design for extreme environments, including orbital and lunar planetary facilities, disaster shelters, polar stations and offshore surface and submersible habitats. This work reflects on related to research problem technical papers, discussions with professionals about their work experience with projects in extreme conditions, and students' workshops debating strategies to form sustainable behavior and design practices.

7. 5. Extreme environments - Design and human factors considerations

   Author : Olga Bannova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme environments; Engineering; Engineer; Architect; Design Planning; Architecture; Multidisciplinary and Trans-disciplinary Design and Planning; Human Factors;

   Abstract : The starting point of this research is based on my experience at SICSA performing research and design for extreme environments, including orbital and lunar planetary facilities, disaster shelters, polar stations and offshore surface and submersible habitats. This thesis explores what aspects and issues of design and planning processes in extreme environments have to be addressed in a similar way and therefore may be used as a basis for further work toward PhD thesis to develop a methodological planning tool or matrix.
