  3. 12. Efficient IoT Framework for Industrial Applications

    Författare :Pablo Puñal Pereira; Jens Eliasson; Jerker Delsing; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : The use of low-power wireless sensors and actuators with networking support in in-dustry has increased over the past decade. New generations of microcontrollers, new hardware for communication, and the use of standardized protocols such as the Internet Protocol have resulted in more possibilities for interoperability than ever before.

  4. 13. An investigation of hybrid maps for mobile robots

    Författare :Pär Buschka; Alessandro Saffiotti; Christian Freksa; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile robot; Hybrid map; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : Autonomous robots typically rely on internal representations of the environment, or maps, to plan and execute their tasks. Several types of maps have been proposed in the literature, and there is general consensus that different types have different advantages and limitations, and that each type is more suited to certain tasks and less to others.

  5. 14. Impulse Radio UWB for the Internet-of-Things : A Study on UHF/UWB Hybrid Solution

    Författare :Zhuo Zou; Hannu Tenhunen; Tor Sverre Lande; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-Wideband; impulse radio; IR-UWB; RFID; asymmetric links; UHF UWB hybrid; wireless sensing; energy detection; low power; radio receiver; positioning; Internet-of-Things;

    Sammanfattning : This dissertation investigates Ultra-Wideband (UWB) techniques for the next generation Radio Frequency Identification (RFID) towards the Internet-of-Things (IoT). In particular, an ultra-high frequency (UHF) wireless-powered UWB radio (UHF/UWB hybrid) with asymmetric links is explored from system architecture to circuit implementation. LÄS MER

  7. 15. Adaptive Microarchitectural Optimizations to Improve Performance and Security of Multi-Core Architectures

    Författare :Nadja Holtryd; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Core Architectures; Bandwidth Partitioning; Prefetch Throttling; Cache Partitioning; Microarchitectural Optimizations; Side-channel Attacks;

    Sammanfattning : With the current technological barriers, microarchitectural optimizations are increasingly important to ensure performance scalability of computing systems. The shift to multi-core architectures increases the demands on the memory system, and amplifies the role of microarchitectural optimizations in performance improvement. LÄS MER
