1. 1. Energy efficiency improvements in logistics as a means to environmental sustainability: The case of capacity utilisation in road freight transportation

   Författare :Jessica Wehner; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Capacity utilisation; household logistics capability; system levels; distribution structure; logistics system; energy efficiency; last-mile fulfilment; overcapacity; system boundaries; road freight transportation;

   Sammanfattning : The energy consumption in logistics, and especially in road freight transportation, is steadily increasing and with that the greenhouse gas emissions which have a negative impact on the environment. In order to improve environmental sustainability of logistics, a change in the actors’ behaviour and policies is needed since the development of technology alone is not sufficient. LÄS MER

3. 2. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

   Författare :Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

   Sammanfattning : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). LÄS MER

4. 3. Capacity Pooling in Healthcare Systems

   Författare :Carina Fagefors; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; volume flexibility; healthcare management; portfolio theory; capacity pools; capacity management;

   Sammanfattning : Healthcare systems are facing a continuously increasing demand for care while healthcare providers express a need for additional capacity. However, increased capacity in healthcare systems will not be a sufficient option in the near future, and previous research has found a need to improve healthcare capacity planning and management.

5. 4. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

   Författare :Hördur Haraldsson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Dynamics; System Analysis; group model building; modelling procedures; innovation phases; modelling workflow; Natural science; Naturvetenskap; Technological sciences; Teknik;

   Sammanfattning : System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. LÄS MER

7. 5. Evaluation of Variable Speed Limits : Empirical Evidence and Simulation Analysis of Stockholm’s Motorway Control System

   Författare :Albania Nissan; Haris N. Koutsopoulos; Tomer Toledo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorway Control System; Mainline Control; Variable Speed Limits; Driver Behavior; Capacity; Intelligent Transport Systems; microsimulation model; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Mechanical energy engineering; Mekanisk energiteknik; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : Variable Speed Limits (VSL) are often used to improve traffic conditions on congested motorways. VSL can be implemented as mandatory or advisory. The objective of the thesis isto study in detail the effectiveness of VSL. The focus is on both, design parameters and conditions under which VSL are most effective. LÄS MER
