1. 1. Exploring affordability in concept generation for complex defence products

   Författare :Daniel Amann; Mats Magnusson; Ingrid Kihlander; Poul Kyvsgaard Hansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affordability; complex product systems; concept generation; CoPS; defence; front end of innovation; innovation management; product development; tournament goods; Machine Design; Maskinkonstruktion;

   Sammanfattning : National defence budgets face pressure from intergenerational escalating costs for complex defence products, such as fighter aircraft and submarines. These escalating costs originate from ever-increasing performance requirements due to the competitive nature of warfare. In combat, only winning is good enough. LÄS MER

3. 2. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

4. 3. Resource Conservative Manufacturing : New Generation of Manufacturing

   Författare :Farazee Mohammad Abdullah Asif; Mihai Nicolescu; Carmine Bianchi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Conservative Manufacturing; Multiple Lifecycle; System Dynamics;

   Sammanfattning : The question of resource scarcity and emerging pressure of environmentallegislations have put the manufacturing industry with a new challenge. On theone side, there is a huge population that demands a large quantity ofcommodities, on the other side, these demands have to be met by minimumresources and with permissible pollution that the earth’s ecosystem can handle.
