  2. 21. Wideband CMOS Data Converters for Linear and Efficient mmWave Transmitters

    Author : Victor Åberg; Chalmers tekniska högskola; []
    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; CMOS; Efficient; MIMO; Predistortion; mmWave; RF-DAC; Wideband; SAR ADC; Linear; Linearization;

    Abstract : With continuously increasing demands for wireless connectivity, higher carrier frequencies and wider bandwidths are explored. To overcome a limited transmit power at these higher carrier frequencies, multiple input multiple output (MIMO) systems, with a large number of transmitters and antennas, are used to direct the transmitted power towards the user.

  4. 22. A Two-Stroke Range Extender Engine For Heavy Duty BEV applications

    Author : Lennarth Zander; Chalmers tekniska högskola; []
    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; gas exchange; after burner; single cylinder; Two-stroke engine; Range extender; BEV; Battery electric vehicles;

    Abstract : A back-up range extender (REX) is proposed to support battery electric vehicles (BEV) for heavy duty applications. A single cylinder crank case scavenged two-stroke SI-internal combustion engine (ICE) with a turbocharger system is considered powerful and small enough to be installed directly on the existing electric machine in the electric powertrain.

  5. 23. Formal Methods and Safety for Automated Vehicles: Modeling, Abstractions, and Synthesis of Tactical Planners

    Author : Jonas Krook; Chalmers tekniska högskola; []
    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; automated vehicles; Formal methods; formal synthesis; tactical planning; supervisory control theory; automatic abstraction.; safety case; model checking; formal verification; reactive synthesis;

    Abstract : One goal of developing automated road vehicles is to completely free people from driving tasks. Automated vehicles with no human driver must handle all traffic situations that human drivers are expected to handle, possibly more. READ MORE

  6. 24. A functional approach to heterogeneous computing in embedded systems

    Author : Markus Aronsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Developing programs for embedded systems presents quite a challenge; not only should programs be resource efficient, as they operate under memory and timing constraints, but they should also take full advantage of the hardware to achieve maximum performance. Since performance is such a significant factor in the design of embedded systems, modern systems typically incorporate more than one kind of processing element to benefit from specialized processing capabilities.
