  1. 1. Characterization of Small Antennas & Wireless Devices for MIMO Systems in Multipath & Line-of-Sight

    Author : Ahmed Hussain; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; USRP; OTA; SDR; RIMP; TRP; TIS; Reverberation chamber; Rayleigh; MIMO; LOS; LTE; Throughput;

    Abstract : The current thesis investigates over-the-air (OTA) performance characterization of small antennas and wireless terminals in rich isotropic multipath (RIMP) environment, as well as in pure line-of-sight (LOS) environment when taking into account the random positions and orientations of the mobile terminals caused by the realistic user behavior. The latest mobile wireless terminals such as smart phones and tablets can be used in any random orientation thereby making even a received LOS-component appear as a random voltage at the antenna ports over time.

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Socio-technical system; innovation system; transition; MLP; TIS; low emission future; electric vehicles; high voltage transmission grid; Sweden; Norway; Denmark; Finland; United Kingdom; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : Today humankind is facing numerous sustainability challenges that require us to question CO2 intensive practices like those present in the transport and energy sector. To meet those challenges, many countries have adopted ambitious climate targets. Achieving such targets requires an understanding of the wider socio-technical context of transitions. READ MORE

  3. 3. Residential solar photovoltaics deployment: barriers and drivers in space

    University dissertation from IIIEE, Lund University

    Author : Alvar Palm; Lund University.; Lunds universitet.; [2017]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Solar photovoltaics PV ; renewable energy; sustainability transitions; technology deployment; diffusion of innovations; barriers; drivers; space; technological innovation system TIS ; technology adoption; business model; peer effects;

    Abstract : In order to support a sustainability transition in the energy sector, actors need knowledge about barriers and drivers to the deployment of clean energy technologies. Solar photovoltaics (PV) is a renewable energy technology that is technically mature and on the verge of becoming economically competitive in numerous regions around the world. READ MORE

  4. 4. Energy innovation and sustainability transitions in China: Building energy efficiency and renewable energy

    University dissertation from IIIEE, Lund University

    Author : Jingjing Zhang; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The assumption underlying this thesis is that both technological development and institutional and structural change are required to achieve a more sustainable building sector in China. Earlier literature has taken an approach based on the technological innovation system (TIS) to evaluate and understand the dynamics of technology development and change processes. READ MORE

  5. 5. SCALING UP RENEWABLE ENERGY TECHNOLOGIES - The role of resource mobilisation in the growth of technological innovation systems

    University dissertation from IIIEE, Lund University

    Author : Kersti Karltorp; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource mobilisation.; scaling up technologies; Wind power; technological innovation system; biorefineries;

    Abstract : Rapid and large-scale diffusion of renewable energy technologies is needed to avoid severe climate changes that would dramatically affect the conditions for human life on Earth. To scale up these technologies involves technological development, but also the alteration of structures that are locked-in to established socio-technical systems. READ MORE
