1. 1. The complexity and variability of individuals' activity-travel patterns in Indonesia

   Författare :Dimas Bayu Endrayana Dharmowijoyo; Yusak Susilo; Anders Karlström; Frank Wiltox; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; day-to-day variability; needs-constraints interaction; non-instrumental variables; health condition; Transportvetenskap; Transport Science;

   Sammanfattning : Considering an individual’s day-to-day variability of activity-travel patterns will provide a more complete description of how an individual behaves to adapt the changing constraints and resources on different days. Without this day-to-day variability understanding, the individual’s behaviour would not be fully grasped and any suggested policy, planning and development would not completely achieve their desired objectives.

   Sammanfattning : Information Technology (IT) is a cornerstone of our modern society and essential for governments' management of public services, economic growth and national security. Consequently, it is of importance that IT systems are kept in a dependable and secure state. LÄS MER

4. 3. Evaluation of bus priority strategiesin coordinated traffic signal systems

   Författare :Johan Wahlstedt; Karl-Lennart Bång; Haris Koutsopoulos; Lars-Göran Mattsson; Kosonen Iisakki; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bus priority; public transport priority; transit priority; PTSP; TSP; traffic signal; traffic signal control; traffic signal control systems; self-optimising signal control; PRIBUSS; SIL simulation; traffic simulation; Transportvetenskap; Transport Science;

   Sammanfattning : Increasing congestion and environmental concerns have evoked an interest in promoting urban Public Transport (PT) the last decades. In 2012 the City of Stockholm adopted an “Urban mobility strategy” stating that public transport, cycling and walking should be prioritised over cars in central Stockholm. LÄS MER

5. 4. Near-infrared photodetectors based on Si/SiGe nanostructures

   Författare :Anders Elfving; Wei-Xin Ni; Thomas P. Pearsall; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SiGe; Ge dots; nanostructures; molecular beam epitaxy; photodetector; Semiconductor physics; Halvledarfysik;

   Sammanfattning : Two types of photodetectors containing Ge/Si quantum dots have been fabricated based on materials grown by molecular beam epitaxy and characterized with several experimental techniques. The aim was to study new device architectures with the implementation of Ge nanostructures, in order to obtain high detection efficiency in the near infrared range at room temperature. LÄS MER

7. 5. Atomic and Electronic Structures of Clean and Metal Adsorbed Si and Ge Surfaces : An Experimental and Theoretical Study

   Författare :Johan Eriksson; Roger Uhrberg; Karsten Horn; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : In this work, a selection of unresolved topics regarding the electronic and atomic structures of Si and Ge surfaces, both clean ones and those modified by metal adsorbates, are addressed. The results presented have been obtained using theoretical calculations and experimental techniques such as photoelectron spectroscopy (PES), low energy electron diffraction (LEED) and scanning tunneling microscopy (STM).
