  1. 1. No limits the 20th century discourse of economic growth

    University dissertation from Umeå : Umeå universitet

    Author : Eva Friman; Umeå universitet.; [2002]
    Keywords : HUMANIORA; HUMANITIES; economic growth; growth discourse; development discourse; history of economics; environmental economics; ecological economics; ecomodernism; modernist economic ethos; narrative; power of language; limits to growth;

    Abstract : The breakthrough of the concept of economic growth in economics marks a paradigm shift in thinking about the economy and its place in 'reality.' This thesis analyzes the 20th century discourse of economic growth, focusing its unlimited connotations. The thesis consists of four case studies, two introductory parts and a concluding dis­cussion.

  2. 2. Fundamental Estimation and Detection Limits in Linear Non-Gaussian Systems

    University dissertation from Institutionen för systemteknik

    Author : Gustaf Hendeby; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; Detection; Linear systems; Non-Gaussian; Limits; GLR; CRLB; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Abstract : Many methods used for estimation and detection consider only the mean and variance of the involved noise instead of the full noise descriptions. One reason for this is that the mathematics is often considerably simplified this way. READ MORE

  3. 3. Fundamental Limits in Wireless Wideband Networking

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Tan Tai Do; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The rapid growth of the wireless communication industry recently does not only bring opportunities but also challenges on developing radio technologies and solutions that can support high data rate as well as reliable and efficient communications. Two fundamental factors that limit the transmission rate are the available transmit energy and the available bandwidth. READ MORE

  4. 4. Millimeter-wave Networking Fundamental Limits, Scalable Algorithms, and Design Insights

    University dissertation from KTH Royal Institute of Technology

    Author : Hossein Shokri-Ghadikolaei; KTH.; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The current demands for extremely high data rate wireless services and the spectrum scarcity at the sub-6 GHz bands are forcefully motivating the use of the millimeter-wave (mmWave) frequencies. The main characteristics of mmWave communications are severe attenuation, sparse-scattering environment, huge bandwidth, vulnerability to obstacles and antenna misalignment, massive beamforming, and possible noise-limited operation.

    Abstract : Variable Speed Limits (VSL) are often used to improve traffic conditions on congested motorways. VSL can be implemented as mandatory or advisory. The objective of the thesis isto study in detail the effectiveness of VSL. The focus is on both, design parameters and conditions under which VSL are most effective. READ MORE
