  1. 1. Ink-jet printing of thin film transistors based on carbon nanotubes

    Författare :Jiantong Li; Shi-Li Zhang; Håkan Olin; Muhammad Ashraful Alam; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-walled carbon nanotube; thin film transistor; ink-jet printing; Monte Carlo simulation; stick percolation; composite network; flexible electronics; Electronics; Elektronik;

    Sammanfattning : The outstanding electrical and mechanical properties of single-walled carbon nanotubes (SWCNTs) may offer solutions to realizing high-mobility and high-bendability thin-film transistors (TFTs) for the emerging flexible electronics. This thesis aims to develop low-cost ink-jet printing techniques for high-performance TFTs based on pristine SWCNTs. LÄS MER

  3. 2. Link Reliability in Cooperative Relaying Using Network Coding

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Network Coding; Multiple Access Relay Channel; Telecommunication; Telekommunikation; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Demand for high data rates is increasing rapidly for future wireless systems.This trend is due to the increase in the number of mobile subscribers that need bandwidth hungry multimedia applications anywhere, anytime. Fourth generation cellular systems like IMT-advanced are being developed to meet these requirements. LÄS MER

  4. 3. Robust Multimedia Communications over Packet Networks

    Författare :Guoqiang Zhang; W. Bastiaan Kleijn; Vinay Vaishampayan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : Multimedia communications over packet networks, and in particular the voice over IP (VoIP) application, have become an integral part of society. However, the unreliable and heterogeneous nature of packet networks has led to a best-effort delivery of services. LÄS MER

  5. 4. A revised perspective on Disruptive Innovation - Exploring Value, Networks and Business models

    Författare :Christian Sandström; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Disruptive innovation; discontinuous; Facit; network; business model; value; Hasselblad;

    Sammanfattning : The concept of disruptive innovation has received much attention in recent years. These innovations can be defined as offering an initially lower performance while at the same time bringing some new attributes to the market. LÄS MER

  7. 5. Spatial positioning : method development for spatial analysis of interaction in buildings

    Författare :Henrik Markhede; Jesper Steen; John Peponis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : In offices, knowledge sharing largely depends on everyday face-to-face interaction patterns. These interaction patterns may depend on how employees move through the office space. This thesis explores how these spatial relations influence individual choices with respect to employee movements or routes. LÄS MER
