  1. 16. On conceptual development of modular products - Development of supporting tools for the modularisation process

    University dissertation from Stockholm : Industriell produktion

    Author : Roger Stake; KTH.; [2000]
    Keywords : Conceptual product development; modular products; product families; module drivers; tools;

    Abstract : The research work detailed in this dissertation relates tothe development of modular products and product families.Historically, product variants have been developed more or lessindependently; but in order to stay competitive in today’sbusiness environment where globalisation and explosion ofvariety are some of the buzzwords, products should be developedas a product family.

  2. 17. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing

    University dissertation from Stockholm : Industriell produktion

    Author : Faisal Altaf; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; converters; electrified vehicles.; model predictive control; thermal balancing; SOC balancing; battery control; Modular batteries;

    Abstract : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. READ MORE

  3. 18. Modeling and Design of Modular Multilevel Converters for Grid Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kalle Ilves; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular multilevel converter; feed-forward control; modulation; switching frequency; energy storage;

    Abstract : This thesis aims to bring clarity to the dimensioning aspects and limiting factors of the modular multilevel converter (MMC). Special consideration is given to the dc capacitors in the submodules as they are a driving factor for the size and weight of the converter. READ MORE

  4. 19. Efficient Modeling of Modular Multilevel Converters for HVDC Transmission Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Noman Ahmed; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Voltage dc; Modular Multilevel Converter; Voltage-Source Converter; HVDC Grids; Multiterminal DC Systems; Hybrid HVDC Breaker; Modeling; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The drive towards getting more and more electrical energy from renewable sources, requires more efficient electric transmission systems. A stronger grid, with more controllability and higher capacity, that can handle power fluctuations due to a mismatch between generation and load is also needed. READ MORE

  5. 20. The Modular Domain Structure of ASF/SF2: Significance for its Function as a Regulator of RNA Splicing

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Vita Dauksaite; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; pre-mRNA splicing; alternative splicing; splicing regulation; SR proteins; ASF SF2; modular domains; adenovirus; MLTU L1; E1A; MS2; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Abstract : ASF/SF2 is an essential splicing factor, required for constitutive splicing, and functioning as a regulator of alternative splicing. ASF/SF2 is modular in structure and contains two amino-terminal RNA binding domains (RBD1 and RBD2), and a carboxy-terminal RS domain. READ MORE
