2. 1. Public e-Service Stakeholders : A study on who matters for public e-service development and implementation

   Author : Ida Lindgren; Karin Axelsson; Göran Goldkuhl; Leif Flak; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public e-service; stakeholders; e-government; user involvement; Offentliga e-tjänster; intressenter; e-förvaltning; användarmedverkan;

   Abstract : Public e-services are progressively used as a means for governmental agencies to interact and exchange information with citizens and businesses. These services are typically Internet-based and are meant to fulfill the three overarching objectives of egovernment; (1) to improve citizens’ interactions with the government, (2) to make governmental organizations more efficient and effective, and (3) to increase the transparency of government and lead to a more democratic society.

4. 2. Design, Fabrication, and Characterization of Nano-Photonic Components Based on Silicon and Plasmonic Material

   Author : Liu Liu; Lars Thylén; Roe Baets; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nano-photonics; finite-difference time-domain method; finite-difference mode solver; amorphous silicon; silicon nanowire; arrayed waveguide grating; photonic crystal; Photonics; Fotonik;

   Abstract : Size reduction is a key issue in the development of contemporary integrated photonics. This thesis is mainly devoted to study some integrated photonic components in sub-wavelength or nanometric scales, both theoretically and experimentally. READ MORE

5. 3. Characterization and Energy Calibration of a Silicon-Strip Detector for Photon-Counting Spectral Computed Tomography

   Author : Xuejin Liu; Mats Danielsson; Sarah E Bohndiek; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Technology; Medicinsk teknologi;

   Abstract : Multibin photon-counting x-ray detectors are promising candidates to be applied in next generation computed tomography (CT), whereby energy information from a broad x-ray spectrum can be extracted and properly used for improving image quality and correspondingly reducing radiation dose. A silicon-strip detector has been developed for spectral CT, which operates in photon-counting mode and allows pulse-height discrimination with 8 adjustable energy bins. READ MORE

6. 4. Challenges with Driverless and Unattended Train Operations

   Author : Emil Jansson; Oskar Fröidh; Nils O.E. Olsson; Ingrid Johansson; Carl-William Palmqvist; Olov Lindfeldt; Ronghui Liu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway; Automatic train operation; Driverless trains; Train driver; Roles; Automation challenges; Human senses; Trackside sensors; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

   Abstract : Demand for transportation continues to increase, for both freight and passenger services. One of the most energy-efficient modes of transportation is rail. One solution to increase the attractiveness of rail transport is to introduce automatic train operation (ATO) with a high grade of automation (GoA). READ MORE

7. 5. Reassembling Local E-Government : A study of actors’ translations of digitalisation in public administration

   Author : Mariana S. Gustafsson; Elin Wihlborg; Bo Persson; Antonio Cordella; Linköpings universitet; []
