  1. 1. Nanoimprint Lithography Based Nanoelectromechanical Device Fabrication

    Författare :Gang Luo; Fasta tillståndets fysik; []

    Sammanfattning : This thesis presents studies concerning the development of nanoimprint lithography technology, nanoimprint lithography-based nanofabrication, as well as the production of NEMS devices and their characterization. It can be divided into the following parts: The first part introduces different NIL stamp fabricating methods and processes. LÄS MER

  2. 2. Time and Frequency Transfer using Passive Techniques in Active Fiber Optic Networks

    Författare :Sven-Christian Ebenhag; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Fiber link; optical fiber.; Global positioning system GPS ; fiber network; time transfer; two-way; synchronous optical networking SONET synchronous digital hierarchy SDH ; GPS carrier phase;

    Sammanfattning : For the modern society, high precision time and frequency transfer have become crucial since a large number of systems, such as telecommunication systems, require precise and stable synchronization. Electric power companies use synchronized systems for taking stability measurements and searching for errors in their networks. LÄS MER

  3. 3. The Prima Porta Garden Archaeological Project. Terra sigillata from the Villa of Livia, Rome. Consumption and discard in the early Principate

    Författare :Allan Klynne; Philip Kenrick; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Classical archaeology and ancient history; Villa of Livia; terra sigillata; Central Italian sigillata; fabrics; trade; consumption; discard; refuse; formation processes; chronology.; Antikens kultur och samhällsliv; Classical archaeology and ancient history; Antikens kultur och samhälle; Classical Archaeology and Ancient History; antikens kultur och samhällsliv;

    Sammanfattning : This study examines a corpus of Italian sigillata from the Villa of Livia outside Rome, and presents the excavations during which it was found. Most of the material stems from archaeologically secure contexts, a refuse tip and dump dating to the late Augustan and Neronian periods respectively. LÄS MER

  4. 4. Development of Nanoimprint Lithography for Fabrication of Electrochemical Transducers

    Författare :Marc Beck; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemistry; interdigitated array; anti-adhesion; anti-sticking; stamp; mold; monolayer deposition; Fysik; post-imprint processes; Physics; transducer; nanoimprint lithography; sensor; Fysicumarkivet A:2003:Beck;

    Sammanfattning : This thesis gives an overview about the current status of nanoimprint lithography, a relatively new nanofabrication tool. The technology is capable for parallel mass production of nm-structured features having a resolution below 10 nm and is usable with high throughput on full wafer scale. LÄS MER

  5. 5. Non-Uniform Sampling in Statistical Signal Processing

    Författare :Frida Eng; Fredrik Gustafsson; Paulo Ferreira; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; signal processing; sampling; stochastic analysis; frequency transform; Automatic control; Reglerteknik;

    Sammanfattning : Non-uniform sampling comes natural in many applications, due to for example imperfect sensors, mismatched clocks or event-triggered phenomena. Examples can be found in automotive industry and data communication as well as medicine and astronomy. LÄS MER
