    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; performance analysis; network calculus; coverage analysis; deployment scheme; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Recently, wireless sensor network (WSN) has become a promising technology with a wide range of applications such as supply chain monitoring and environment surveillance. It is typically composed of multiple tiny devices equipped with limited sensing, computing and wireless communication capabilities. READ MORE

  2. 12. Uncertainty Modelling in Hydrological Applications - Error Propagation Properties of Random Linear Systems

    Author : Jan Agerholm Høybye; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; floods; water quality; prediction uncertainty; differential equations; Stochastic hydrology; random functions; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial conditions. READ MORE

  3. 13. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications

    Author : Henrik Forssell; Ragnar Thobaben; Stefano Tomasin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical layer authentication; mission-critical communica- tions; worst-case performance; queueing delay performance; stochastic net- work calculus; optimal attack strategies.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. READ MORE

  4. 14. Improving Clock Synchronization Performance in Industrial Networks

    Author : Rahul Nandkumar Gore; Elena Lisova; Johan Åkerberg; Mats Björkman; Han Song; Mälardalens universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clock synchronization; Industrial networks; Internet of things; Industry 4.0; Network Calculus; Computer Science; datavetenskap;

    Abstract : The recent advances in cyber-physical systems and industrial internet-of-things (IIoT) have enabled the convergence of information technology (IT) and operational technology (OT) worlds of industrial automation systems achieving higher productivity, reliability, and revenues. The availability of business-critical and production-critical data on the converged network has enabled new and advanced network-centric applications that require time-constrained embedded devices to be connected to “the internet.

  5. 15. A class of infinite dimensional stochastic processes with unbounded diffusion and its associated Dirichlet forms

    Author : John Karlsson; Jörg-Uwe Löbus; Torkel Erhardsson; Hans-Jürgen Engelbert; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of two papers which focuses on a particular diffusion type Dirichlet form  where  Here  is the basis in the Cameron-Martin space, H, consisting of the Schauder functions, and ν denotes the Wiener measure.In Paper I, we let  vary over the space of wiener trajectories in a way that the diffusion operator A is almost everywhere an unbounded operator on the Cameron–Martin space.
