Wideband, Robust Low Noise Amplifier
(Master thesis, 2018)Low noise amplifiers are important parts of receiver units in radio systems that enables communication between military vehicles. The use of such an amplifier in military and maritime equipment poses challenges to the ... -
A Wiener Tauberian theorem for operators and functions
(Peer reviewed; Journal article, 2021)We prove variants of Wiener's Tauberian theorem in the framework of quantum harmonic analysis, i.e. for convolutions between an absolutely integrable function and a trace class operator, or of two trace class operators. ... -
Wienerization Based Control of Nonlinear Systems
(Chapter, 2022)We present a novel model approximation scheme, named “wienerization”, of nonlinear time invariant systems that uses the systems' nonlinear equilibria maps as the static nonlinearities of Wiener models. We show conditions ... -
Wienerization of systems in nonlinear control canonical normal form
(Chapter, 2022)We extend the concept of model approximation via wienerization to systems in nonlinear control canonical normal form. We elaborate on the conditions for, and implications of, analytically separating nonlinear input affine ... -
WiGiG som aksessteknologi - et supplement til fiberinfrastruktur?
(Bachelor thesis, 2019)Hensikten med denne oppgaven er å vurdere anvendeligheten av WiGiG som aksessteknologi. Oppgaven beskriver og evaluerer resultater knyttet til et pilotprosjekt Lyse har gjennomført i et boligfelt i Sandnes. Ved å samle inn ... -
Wiki i skolen
(Master thesis, 2010)Prosjektet gikk ut på å sette opp Wiki-programvare for en ungdomsskole, og undersøke hvordan elever brukte denne, samt sammenligne bruken mot kjente sosiale nettverk som Wikipedia. Et av forskningsspørsmålene var hvorvidt ... -
