  1. 1. Multiconductor transmission lines wideband modeling : A delay-rational Green’s-function-based method

    Author : Maria De Lauretis; Jonas Ekman; Giulio Antonini; Wil Schilders; Luleå tekniska universitet; []

    Abstract : The performance of variable-frequency drives (VFDs) commonly used in energy production plants can be severely affected by electromagnetic (EM) noise in the form of conducted disturbances.A VFD is composed of an inverter, a motor, and a connecting power cable. READ MORE

  2. 2. A Brave New Workplace: Disclosing the smart and the dark sides of the alternative office spaces

    Author : Claudia Manca; Matti Kaulio; Mercedes Grijalvo; Miguel Palacios; Viviane Sergi; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; alternative workplace; workplace flexibility; new ways of working; activity-based work; collaborative space; tensions; paradoxes; space production; social space; alternativ arbetsplats; flexibilitet på arbetsplatsen; nya arbetssätt; aktivitetsbaserat arbete; samarbetsutrymme; spänningar; paradoxer; skapande av rum; socialt utrymme; Industrial Economics and Management; Industriell ekonomi och organisation;

    Abstract : In recent decades, several knowledge work organizations have introduced alternative workplaces (AWs) that are implemented through flexible and collaborative office models. Their rapid diffusion has been prompted by the deterministic assumption that these may influence workers’ relations and behaviors in the office, in a way that is conducive to greater collaboration and adaptive flexibility.

  3. 3. Aggregation of Plug-in Electric Vehicles in Power Systems for Primary Frequency Control

    Author : Seyedmahdi Izadkhast; Mehrdad Ghandhari; Garcia-Gonzalez Pablo; Frias Pablo; Ignacio Egido Cortés; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aggregation; Plug-in Electric Vehicles; Primary Frequency Control; Aggregeren; Plug-in Elektrische Voertuigen; Primaire Reserve; Laddbara Bilar; Elnätet; Primär Frekvensreglering; Agregación; Vehículos Eléctricos Enchufables PEVs ; Control Primario de Frecuencia PFC ; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The number of plug-in electric vehicles (PEVs) is likely to increase in the near future and these vehicles will probably be connected to the electric grid most of the day time. PEVs are interesting options to provide a wide variety of services such as primary frequency control (PFC), because they are able to quickly control their active power using electronic power converters.

  4. 4. Generation of magnetic fields on galactic scale

    Author : Fabio Del Sordo; Axel Brandenburg; Oliver Gressel; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Magnetic fields; galaxies; astronomi; Astronomy;

    Abstract : In these pages we will go through the topic of astrophysical magnetic fields, focusing on galactic fields, their observation and the theories that have been developed for a proper understanding of the these physical phenomena.We review the main work in the study of galactic magnetic fields, often seeing how it is important to deal with problems of general validity in order to be able to point out the right elements needed for a correct interpretation of specific situations.

  5. 5. Secure System Virtualization : End-to-End Verification of Memory Isolation

    Author : Hamed Nemati; Mads Dam; Gustavo Betarte; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Platform Security; Hypervisor; Formal Verification; Theorem Proving; HOL4; Cache attack; Security Monitor; Information Flow; Datalogi; Computer Science;

    Abstract : Over the last years, security-kernels have played a promising role in reshaping the landscape of platform security on embedded devices. Security-kernels, such as separation kernels, enable constructing high-assurance mixed-criticality execution platforms on a small TCB, which enforces isolation between components. READ MORE
