  1. 1. Real-Time Certified MPC : Reliable Active-Set QP Solvers

    Författare :Daniel Arnström; Daniel Axehill; Anders Hansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In Model Predictive Control (MPC), optimization problems are solved recurrently to produce control actions. When MPC is used in real time to control safety-critical systems, it is important to solve these optimization problems with guarantees on the worst-case execution time. LÄS MER

  3. 2. Recovery actions in freight transport through real-time disruption management

    Författare :Per Wide; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; freight transport; transport system; operational planning; proactive recovery actions; Disruption management; real-time information;

    Sammanfattning : This thesis focuses on the management of disruption in freight transport. The management of disruption is of importance to achieve planned efficiency in the transport system by mitigating or avoiding the impacts of disruptions, such as late arrivals of deliveries. LÄS MER

  4. 3. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

    Författare :Sanny Syberfeldt; Sten Andler; Jörgen Hansson; Sang H. Son; Alejandro Buchmann; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Computer science; Datalogi; Teknik;

    Sammanfattning : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. LÄS MER

  5. 4. A flexible real-time solution to modular design of an adaptive control system for turning

    Författare :Thomas Lundholm; Bo Lindström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turning; adaptive control; real-time control; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : This thesis deals with the organization of an adaptive control system for turning and, furthermore, the development of an integration framework for subsystems in the adaptive control system. The thesis is organized in three main parts. LÄS MER

  7. 5. Real-Time GPU Techniques for Advanced Lighting Phenomena

    Författare :Markus Billeter; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shading; Rendering; Participating Media; Volumetric Shadows; Mobile Graphics; Scattering; Computer Graphics; GPGPU; Many-Light;

    Sammanfattning : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. LÄS MER
