  1. 1. On the Modeling of Porous Media with Emphasis on Localization

    Författare :Jonas Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded band; material instability; bifurcation; FEM; softening plasticity; consolidation; shear band; porous media; localization;

    Sammanfattning : The mechanics of porous media is nowadays relevant in a broad spectrum of engineering applications. In the case of geomaterials, the description of the mechanical behavior is complicated by the fact that the deformation characteristics involve (strain) localization, which is indeed the main topic of this thesis.

  3. 2. Reconfigurable Receiver Front-Ends for Advanced Telecommunication Technologies

    Författare :Iman Ghotbi; Integrerade elektroniksystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; Receiver; Filter; Low-noise amplifier; FD-SOI; Calibration;

    Sammanfattning : The exponential growth of converging technologies, including augmented reality, autonomous vehicles, machine-to-machine and machine-to-human interactions, biomedical and environmental sensory systems, and artificial intelligence, is driving the need for robust infrastructural systems capable of handling vast data volumes between end users and service providers. This demand has prompted a significant evolution in wireless communication, with 5G and subsequent generations requiring exponentially improved spectral and energy efficiency compared to their predecessors.

  4. 3. Robust Low-Power Wide Area Networks for Sports and Health

    Författare :Charalampos Orfanidis; Martin Jacobsson; Dimitrios Zorbas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology and Health; Teknik och hälsa;

    Sammanfattning : Low-Power Wide Area Networks (LPWANs) has enriched the IoT ecosystem with new features and application scenarios. LPWANs offer long range communication and can be used to connect devices that are divided by long distances and offer connectivity to remote areas where cellular networks are not accessible. LÄS MER

  5. 4. MM-wave integrated RF-MEMS tunable cavity resonators, filters and ultra-low phase-noise oscillators

    Författare :Dragos Dancila; Isabelle Huynen; Universite catholique de Louvain (UCL); []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Within the Microelectronics Industry, the core research is focused on the realization of the Moore's law, which states that circuit density doubles every 24 months, shaping the framework of the More of Moore paradigm. However, Moore's law is expected to end, as devices are reaching limitations inherent to the approach of the atomical dimensions. LÄS MER

  7. 5. Printable Green RFID Antennas for Embedded Sensors

    Författare :Yasar Amin; Hannu Tenhunen; Lirong Zheng; Qiang Chen; Leena Ukkonen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RFID; Antennas; Inkjet printing; Wideband Antennas; Narrow-band Antennas;

    Sammanfattning : In the recent years, radio-frequency identification (RFID) technology has been widely integrated into modern society applications, ranging from barcode successor to retail supply chain, remote monitoring, detection and healthcare, for instance. In general, an RFID tag or transponder is composed of an antenna and an application-specific integrated circuit chip. LÄS MER
