    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; discrete event systems; cyber-physical systems; robotics middleware; camera calibration; machine learning; data flow; Machine vision;

    Sammanfattning : Vision-based robotics is an ever-growing field within industrial automation. Demands for greater flexibility and higher quality motivate manufacturing companies to adopt these technologies for such tasks as material handling, assembly, and inspection. LÄS MER

  3. 22. Behavioral modeling of wireless transmitters for distortion mitigation

    Författare :Ali Soltani Tehrani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear models; wireless communications.; computational complexity; I Q imbalance; digital predistortion; Volterra series; transmitter; power amplifier; Behavioral modeling;

    Sammanfattning : As the demand for high speed and reliable wireless communication increases, theimportance of having a linear transmitter has enhanced. Distortions created by thetransmitter, such as power amplifier nonlinearity and I/Q imbalance, diminish thefidelity and limit the performance of wireless systems, if left undealt with. LÄS MER

  4. 23. Efficient Memory Modeling During Simulation and Native Execution

    Författare :Nikos Nikoleris; Erik Hagersten; Lieven Eeckhout; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance analysis; cache performance; multicore performance; memory system; memory bandwidth; memory contention; performance prediction; multi-threading; multiprocessing systems; program diagnostics; commodity multicores; multithreaded program resource requirements; performance counters; scalability bottleneck; scalability improvement; Computer Science; Datavetenskap;

    Sammanfattning : Application performance on computer processors depends on a number of complex architectural and microarchitectural design decisions. Consequently, computer architects rely on performance modeling to improve future processors without building prototypes. LÄS MER

  5. 24. Understanding Multicore Performance : Efficient Memory System Modeling and Simulation

    Författare :Andreas Sandberg; Erik Hagersten; David Black-Schaffer; David A. Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

    Sammanfattning : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. LÄS MER

  7. 25. Perspectives on Modeling and Simulation of Urban Systems with Multiple Actors and Subsystems

    Författare :Elhabib Moustaid; Sebastiaan Meijer; Gunnar Flötteröd; S Rajagopalan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation Modeling; Urban Systems; Expert Knowledge; Complexity Science; Mathematical Modeling; Second Order Effects.; Simulering och modellering; urbana system; expertkunskap; Komplexitetsvetenskap; matematisk modellering; andra graden effekt; Teknik och hälsa; Technology and Health;

    Sammanfattning : Cities are the spaces of the interaction between social, physical, political, and economic entities, which makes planning and intervening in such systems difficult. Urban systems are complex adaptive systems in that their behaviours are often the result of the interaction of their components. LÄS MER
