  3. 17. Intelligence Partitioning for IoT : Communication and Processing Inter-Effects for Smart Camera Implementation

    Författare :Irida Shallari; Mattias O'Nils; Muhammad Imran; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The Internet of Things (IoT) is becoming a tangible reality, with a variety of sensors, devices and data centres interconnected to support scenarios such as Smart City with information about traffic, city administration, health-care services and entertainment. Decomposing these systems into smaller components, results in a variety of requirements for processing and communication resources for each subsystem. LÄS MER

  5. 19. Extending Microsystems to Very High Temperatures and Chemically Harsh Environments

    Författare :Zahra Khaji; Lena Klintberg; Klas Hjort; Greger Thornell; Frank Niklaus; Uppsala universitet; []
    Nyckelord :HTCC; MEMS; MST; Microcombustor; Microthruster; Single-use valve; Wireless pressure sensor; flow sensor; in-situ electroplating; Monopropellant; Platinum; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : Aiming at applications in space exploration as well as for monitoring natural hazards, this thesis focuses on understanding and overcoming the challenges of extending the applicability of microsystems to temperatures above 600°C as well as chemically harsh environments. Alumina and zirconia high-temperature co-fired ceramics (HTCC) with platinum as the conductor material, have in this thesis, been used to manufacture a wide range of high-temperature tolerant miniaturized sensors and actuators, including pressure and flow sensors, valves, a combustor, and liquid monopropellant microthrusters.

    Sammanfattning : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.
