   Sammanfattning : Refrigeration plays a crucial role in many different sectors and consumes about 17% of the electricity produced globally. This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts. LÄS MER

3. 17. Model based construction process management

   Författare :Jarmo Laitinen; KTH; []
   Nyckelord :;

   Sammanfattning : The purpose of this research was to study how the data management of a main contractor can be improved, in order to provide better client value and more cost-efficient production. The research focused on methods for reengineering the information management using product modelling as enabling technology. LÄS MER

4. 18. A Methodology for the Design of Cost Effective Hybrid Vehicles

   Författare :Jonas Hellgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuzzy logic; system engineering; model car; optimal design; evolutionary algorithms; hybrid electric vehicle; alternative powertrain; simulation; modeling; genetic algorithms; fuel cell vehicle; hybrid vehicle;

   Sammanfattning : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. LÄS MER

   Sammanfattning :   This study discusses the tradition of ideal ageing, which emphasizes life-long virtue as an avenue to wisdom. In line with this tradition the senior members of society have been expected to take charge of and to organize their withdrawal from their social engagements, make themselves available to the younger generations needs without (openly) wanting to control them, and impart traditions without insisting that everything remain unchanged.
