  2. 1. On Efficient Transmission Balancing Operation : Capturing the Normal State Frequency and Active Power Dynamics

    Author : Martin Nilsson; Lennart Söder; Julia Matevosyan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Power Dynamics; Frequency Control; Normal State; Power System Balancing; Transmission System Operator; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In an electric power system, there will always be an electric balance. Nevertheless, System Operators (SOs) often uses the term imbalance. Here, the term imbalance refers to the difference between trades and real-time measurements. READ MORE

  4. 2. Washing Machine Design Optimization Based on Dynamics Modeling

    Author : Thomas Nygårds; 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; Experiments; Multiobjective Optimization; Modeling; Vibration dynamics; Washing machine; Suspensions; Semi-active control.; Automatic balancing;

    Abstract : The spinning process in a washing machine is a source of undesired vibrations and noise and may cause discomfort both to the user as well as for the machine itself due to vibrations which have impact on system lifetime, reliability of operation and capacity.The aim of this thesis is to develop mathematical and computational models of a washing machine of modern type and use these models for dynamics analysis and in optimization routines to make improvements of the machine mechanical design.

  5. 3. Optimal Coordination of Flexible Manufacturing Systems, with Automatic Generation of Collision- and Dealock-Free Working Schedule

    Author : Avenir Kobetski; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Visibility Graphs; Scheduling; A*; Mixed Integer Linear Programming; Discrete Event Systems; Velocity Balancing.; Robot Coordination; Supervisory Control Theory; Deterministic Finite Automata; Flexible Manufacturing;

    Abstract : The ever more rapidly changing markets pose high demands on the modern industry, often making it necessary to have varied and frequently updated product portfolios. As a consequence, modern industrial systems need to be easily adaptable to different kinds of products, which makes the use of flexible manufacturing systems (FMS) increasingly popular. READ MORE

  6. 4. On design of complex safety critical automotive systems : a semi-automated approach for balancing profit and safety

    Author : Christian Grante; Matthew Cartmell; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Design processes for complex safety-critical systems in the automotive industry need to evolve in order to address increasing demands for integration of car functions over common networked infrastructures. New processes must address cost and safety concerns, and at the same time maximize profit. READ MORE

  7. 5. Downlink Resource Allocation in Cooperative Wireless Networks

    Author : Jingya Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precoding design; load balancing; relaying; imperfect channel state information; imperfect synchronization; Coordinated multi-point transmission; I Q imbalance; resource allocation; fractional frequency reuse;

    Abstract : Wireless cooperative networks, which is based on exploiting coordination among multiple access nodes, has been considered as a promising approach to improve the spectral efficiency, reduce the energy consumption, and extend the network coverage of future wireless communication systems. In practice, the actual benefit of multi-node cooperation is affected by a variety of factors, including the quality of channel state information (CSI), the constraints on the feedback and backhaul links, hardware impairments, resource allocation and data processing schemes.
