2. 1. Implementation and real-world evaluation of routing protocols for wireless ad hoc networks

   Author : Henrik Lundgren; Per Gunningberg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. To enable communication between nodes that do not have direct radio contact, each node must function as a wireless router and potentially forward data traffic on behalf of the others. READ MORE

4. 2. Implementation and Experimental Evaluation of Wireless Ad hoc Routing Protocols

   Author : Henrik Lundgren; Per Gunningberg; Christian Tschudin; Marco Conti; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wireless ad hoc network; mobile ad hoc network; MANET; experimental evaluation; real world experiments; communication gray zone; gray zone; routing protocol; ad hoc networking; Computer science; Datavetenskap;

   Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. New routing protocols that can adapt to the frequent topology changes induced by node mobility and varying link qualities are needed. READ MORE

5. 3. Thermal Aspects and Electrolyte Mass Transport in Lithium-ion Batteries

   Author : Henrik Lundgren; Göran Lindbgergh; Mårten Behm; Ann Mari Svensson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; Lithium-ion batteries; Electrolytes; Temperature; Modeling; Hybrid electric vehicle; Plug-in hybrid electric vehicle; Chemical Engineering; Kemiteknik;

   Abstract : Temperature is one of the most important parameters for the performance, safety, and aging of lithium-ion batteries and has been linked to all main barriers for widespread commercial success of electric vehicles.The aim of this thesis is to highlight the importance of temperature effects, as well as to provide engineering tools to study these.

6. 4. A Framework for Evaluation and Design of an Integrated Public Transport System

   Author : Carl Henrik Häll; Jan Lundgren; Peter Värbrand; Karin Brundell-Freij; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand responsive; public transport; public transportation; planning; optimization; simulation; Anropsstyrd trafik; kollektivtrafik; kollektivtrafikplanering; optimering; simulering; Other technology; Övriga teknikvetenskaper;

   Abstract : Operators of public transport always try to make their service as attractive as possible, to as many persons as possible and in a so cost effective way as possible. One way to make the service more attractive, especially to elderly and disabled, is to offer door-to-door transportation. READ MORE

7. 5. Modeling and Simulation of Dial-a-Ride and Integrated Public Transport Services

   Author : Carl Henrik Häll; Jan T. Lundgren; Stefan Voss; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dial-a-ride; simulation; optimization; modeling; paratransit; public transport; Other technology; Övriga teknikvetenskaper;

   Abstract : Traditional public transport systems are most often insufficient to provide a good transport service to everyone. Especially, it is not always possible for elderly and disabled persons to use the regular system consisting of timetabled services operating along fixed routes. READ MORE
