  2. 16. Electrical and Optical Properties of AlGaAs/GaAs Aperiodic Superlattices and Resonant Tunneling Diodes. Theory, Design and Applications

    Author : Simon Mang Cao; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exciton-assisted transport; miniband; high-speed quantum electronics; optical properties; ultrafast optoelectronics; field-induced transport; irregular superlattices; nanometer-scale heterostructures; laser diodes; resonant tunneling;

    Abstract : The objective of the work presented in this thesis is to study quantum transport and optical properties of aperiodic superlattices and resonant tunneling diodes using III-V semiconductor heterostructures grown by molecular beam epitaxy. The study follows a procedure of theoretical modeling, computer-aided design and simulation, sample growth, and measurements. READ MORE

  4. 17. Drug and disease effects on the human brain studied by functional MRI

    Author : Love Engström Nordin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: With the advent of magnetic resonance imaging (MRI) technology, various functional MRI (fMRI) techniques have become available for non-invasive neuroscientific studies and clinical diagnostics, which have led to a better understanding of the human brain function in normal and diseased subjects. In order to interpret the fMRI results correctly and design optimal research studies it is important to understand both the potentials and limitations associated with each fMRI technique. READ MORE

  5. 18. On the specification and verification of VLSI systems

    Author : Tony Larsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : System designers now have the opportunity to place on the order of 105-106 transistors on a single chip allowing larger and more complicated systems to be produced at reduced production costs. This opportunity increases the demand for appropriate design automation including tools for synthesis, analysis, and verification. READ MORE

  6. 19. Infants’ Knowledge of Occluded Objects: Evidence of Early Spatiotemporal Representations

    Author : Gustaf Gredebäck; Claes von Hofsten; Janette Atkinson; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; infants; occlusion; gaze; object representations; temporal; spatial; associative rule; extrapolation; Psykologi; Psychology; Psykologi;

    Abstract : This thesis demonstrates that infants represent temporarily non-visible, or occluded, objects. From 4 months of age, infants could accurately predict the reappearance of a moving object after 660 ms of non visibility; indicating accurate spatiotemporal representations. READ MORE

  7. 20. Design of Assured and Efficient Safety-critical Systems

    Author : Nesredin Mahmud; Cristina Seceleanu; Guillermo Rodriguez-Navas; Joost-Pieter Katoen; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems design; safety critical systems; real time systems; formal method; optimization; model checking; Simulink; Computer Science; datavetenskap;

    Abstract : Safety-critical   systems   need   to   be   analyzed rigorously to remove software/specifications errors, that is, their requirements specifications should be unambiguous, comprehensible and consistent, and the software design should conform to the specifications, hence avoiding undesirable system failures. Currently, there is a lack of effective and scalable methods to specify and analyze requirements, and formally analyze the behavioral models of embedded systems. READ MORE
