    • On the moments of a polynomial in one variable 

      Mueger, Michael; Tuset, Lars (Indagationes Mathematicae;Volume 31, Issue 1, January 2020, Journal article; Peer reviewed, 2019-12-10)
      Let f be a non-zero polynomial with complex coefficients and define Mn(f) =R1 0 f(x)n dx. We use ideas of Duistermaat and van der Kallen to prove limsupn→∞ |Mn(f)|1/n > 0. In particular, Mn(f) 6= 0 for infinitely many n ∈ N.
    • On the non-disabled perceptions of four common mobility devices in Norway: A comparative study based on semantic differentials

    • On the normal sheaf of determinantal varieties 

      Kleppe, Jan Oddvar; Miro-Roig, Rosa M. (Journal für die Reine und Angewandte Mathematik;, Journal article; Peer reviewed, 2014-06-18)
      Let X be a standard determinantal scheme X of P^n of codimension c, i.e. a scheme defined by the maximal minors of a tx(t+c-1)homogeneous polynomial matrix A. In this paper, we study the main features of its normal sheaf ...
    • On the Online Classification of Data Streams Using Weak Estimators 

      Tavasoli, Hanane; Oommen, John; Yazidi, Anis (Lecture Notes in Computer Science;9799, Journal article; Peer reviewed, 2016)
      In this paper, we propose a novel online classifier for complex data streams which are generated from non-stationary stochastic properties. Instead of using a single training model and counters to keep important data ...
    • On the Performance of Bidirectional NOMA-SWIPT Enabled IoT Relay Networks 

      Rauniyar, Ashish; Engelstad, Paal E.; Østerbø, Olav Norvald (IEEE Sensors Journal;Volume: 21, Issue 2, Journal article; Peer reviewed, 2020-08-24)
      In this article, a bidirectional relaying (BR) non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIPT) termed as BR NOMA-SWIPT is proposed and investigated for the Internet ...
    • On the performance of differential evolution variants in constrained structural optimization 

      Georgioudakis, Manolis; Plevris, Vagelis (Procedia Manufacturing;volume 44, Peer reviewed; Journal article, 2020-05-04)
      Constrained optimization is a highly important field of engineering as most real-world optimization problems are associated with one or several constraints. Such problems are often challenging to solve due to their complexity ...
