  1. 1. Analyzing technological change using experience curves - a study of the combined cycle gas turbine

    Författare :Ulrika Claeson Colpier; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experience curves; technology assessment.; combined cycle gas turbine; electricity-generation costs; learning curves; technological development;

    Sammanfattning : The aim of this thesis was to analyze and discuss the use of experience curves as a possible instrument for assessing future developments of a specific energy technology: the combined cycle gas turbine (CCGT). The CCGT technology is expected to figure prominently in future energy systems. LÄS MER

  3. 2. Distance Protection of Transmission Lines with High Levels of Series Compensation : A study on frequency and time domain communication independent distance protection for series compensated lines

    Författare :Md Tanbhir Hoq; Nathaniel Taylor; Jianping Wang; Claus Leth Bak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Series capacitor; Series compensation; Transmission line; Distance protection; Incremental quantity; Lissajous curve; RL model; RLC model; Seriekondensator; Seriekompensation; Transmissionslinje; Distansskydd; Inkrementell kvantitet; Lissajous-kurva; RL-modell; RLC-modell; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Series capacitors are used in electric transmission lines to increase their power transfer capacity. They compensate for the inductive reactance of the line. They offer a useful alternative to building new lines, in view of economic and environmental constraints. LÄS MER

  4. 3. Computer-assisted surgery in children

    Författare :Magnus Anderberg; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; minimally invasive; learning curve; laparoscopy; fundoplication; da Vinci® Surgical System; costs; Children; computer-assisted; paediatric surgery; robot; robotic surgery;

    Sammanfattning : Although positive in terms of patient trauma and recovery time, minimally invasive surgery has several technical drawbacks compared with open surgery. The new da Vinci® Surgical System from Intuitive Surgical® offers technical innovations aiming at overcoming these drawbacks and at improving the surgeon’s operating skills, such as the improved 3-D vision, tremor reduction and flexible instruments with a more natural and intuitive range of motion.

    Författare :Monica Karlsson; Engelska; []
    Nyckelord :HUMANIORA; HUMANITIES; Engelska språk och litteratur ; English language and literature; error gravity; proper noun; identification frame; genericness; the zero article; ‘idiomatic’ prepositional use; ‘systematic’ prepositional use; ‘basic’ prepositional use; non-contiguous subject-verb construction; contiguous subject-verb construction; subject-verb concord; fossilisation; restructuring of information; automatisation; interlanguage; cognitive second language acquisition theory; U-curve development; regression; progression; developmental pattern; relative frequency; error score; potential error; developmental continuum; advanced learner; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik; Applied linguistics; foreign languages teaching; sociolinguistics; Tillämpad lingvistik; undervisning i främmande språk; sociolingvistik;

    Sammanfattning : This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. LÄS MER
