2. 1. Architecting Autonomous Automotive Systems : With an emphasis on Cooperative Driving

   Author : Sagar Behere; Martin Törngren; Ivica Crnkovic; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The increasing usage of electronics and software in a modern automobile enables realization of many advanced features. One such feature is autonomous driving. Autonomous driving means that a human driver’s intervention is not required to drive the automobile; rather, theautomobile is capable of driving itself. READ MORE

4. 2. Wireless Sensor Network Systems in Harsh Environments and Antenna Measurement Techniques

   Author : Mathias Grudén; Anders Rydberg; Mikael Gidlund; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Network; Antenna; Jet engine; Train; Reverberation chamber; WISENET; Wisejet; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Abstract : Wireless sensor network (WSN) has become a hot topic lately. By using WSN things that previously were difficult or impossible to measure has now become available. One of the main reasons using WSN for monitoring is to save money by cost optimization and/or increase safety by letting the user knowing the physical status of the monitored structure. READ MORE

5. 3. Mobile Multimedia Multicasting in Future Wireless Systems : A Hybrid Cellular-Broadcasting System Approach

   Author : Aurelian Bria; Jens Zander; Ralf Tönjes; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3G; DVB-H; wireless; multicasting; multimedia; broadcasting; Telecommunication; Telekommunikation;

   Abstract : This dissertation addresses the problem of providing a®ordable mobile mul-timedia services in wide area wireless networks. The approach is to con-sider novel system architectures, based on reusing and sharing of the ex-isting network infrastructure for cellular and terrestrial TV broadcastingsystems. READ MORE

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

   Author : Zhuo Zou; Hannu Tenhunen; Tor Sverre Lande; KTH; []

   Abstract : 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. READ MORE

7. 5. Towards Green Wireless Access Networks : Main Tradeoffs, Deployment Strategies and Measurement Methodologies

   Author : Sibel Tombaz; Jens Zander; Ki Won Sung; Ben Slimane; Peter Legg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; wireless access; green radio; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Wireless access networks today consume 0.5 percent of the global energy. Rapidly growing demand for capacity will further increase the energy consumption. Thus, improving energy efficiency has a great importance not only for environmental awareness but also to lower the operational cost of network operators. READ MORE
