1. 16. Surviving under water : Physiological limitations and technical possibilities

   Författare :Mårten Silvanius; Oskar Frånberg; Rachel Lance; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; diving apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring; decompression; hyperbaric oxygen therapy; Systemteknik; Systems Engineering;

   Sammanfattning : The survival of humans in underwater environments necessitates a comprehensive understanding of both physiological factors and advanced technologies. Diving with self-contained underwater breathing apparatuses (SCUBA) remains one of the most common ways for human underwater activities. LÄS MER

3. 17. Sustainability and development impacts of off-grid electrification in developing countries : An assessment of South Africa's rural electrification program

   Författare :Chukwuma Leonard Azimoh; Björn Karlsson; Boaventura Cuamba; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Off-grid electrification; sustainability; solar home system; hybrid mini-grid; renewable energy; technical challenges; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Previous studies have shown that provision of sustainable electricity supply to rural households is essential to bring development to off-grid populations. For this reason, most developing countries put large efforts into rural electrification programs to stimulate development and reduce poverty. LÄS MER

4. 18. A Framework for Securing e-Government Services : The Case of Tanzania

   Författare :Geoffrey Rwezaura Karokola; Louise Yngström; Mariki Eloff; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; e-Government; information security; maturity models; services; technical security; non-technical security; data- och systemvetenskap; Computer and Systems Sciences;

   Sammanfattning : e-Government services are becoming one of the most important and efficient means by which governments (G) interact with businesses (B) and citizens (C). This has brought not only tremendous opportunities but also serious security challenges. Critical information assets are exposed to current and emerging security risks and threats. LÄS MER

5. 19. Requirements Engineering Supporting Technical Product Management

   Författare :Tony Gorschek; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software engineering; Software Process Assessment and Improvement; SPI; Requirements Engineering; RE; Product Management; Market-driven requirements engineering; MDRE; Requirements abstraction model; RAM; Industry relevant research;

   Sammanfattning : Market-Driven Requirements Engineering (MDRE) handles the continuous flow of requirements in an engineering effort, and is not limited to a development instance but part of technical product management as a whole. The market-driven environment generates large amounts of requirements from multiple sources, internal and external, threatening to overload the technical management of products. LÄS MER

7. 20. Systems Dependability Engineering for Wind Power Applications : Challenges, Concepts, and System-Level Methodologies

   Författare :Idriss El-Thalji; Anders Karlsson; Linnéuniversitetet; []
   Nyckelord :System Dependability; Systems Engineering; Terotechnology; Terotechnology; Systemekonomi;

   Sammanfattning : Complexity and uncertainty have impacted wind power systems and their applications.Commercial wind power asset exhibits complex system behaviour due tostochastic loading characteristics of its installation context. However, differentstakeholders’ practices in whole life cycle processes try to treat multi-disciplinarycomplexity issues. LÄS MER
