Wireless Power and Communication: Implementation of communication in a wireless power transferring system
(Master thesis, 2011)In this report two types of inductive antennas has been characterized, one designed for both power and communication and one designed for communication only. The effects of varying wire size, number of windings and distance ... -
Wireless Sensor Networks for Detection and Localization of Subsea Oil Leakages
(Journal article; Peer reviewed, 2021)This work studies the impact of Wireless Sensor Networks (WSNs) for oil spill detection and localization in Subsea Production Systems. The case study is the Goliat FPSO, with a realistic assumption about the presence of a ... -
Wireless Video Capsule Endoscopy - Adaptive Coding for Parameters Update and Low Complexity Region-of-Interest Encoding
(Master thesis, 2016)Wireless capsule endoscopy (WCE) is a non-invasive diagnostic method to investigate diseases in the human gastrointestinal (GI) tract. Specifically, the WCE allows for physicians to visually inspect the GI tract of the ... -
Wireless Video Capsule Endoscopy Prototype Utilizing a Backscatter Transceiver for High Data Rate Transmission
(Master thesis, 2022)Kapselendoskopi er en viktig medisinsk applikasjon for sikrere, smertefri og muligens mer nøyaktig påvisning av sykdommer i mage-tarmkanalen, som kreftpolypper i tykktarmen. Trådløs Video Kapselendoskopi (WCE) ble ... -
WISA vs. WLAN: Co-existence challenges: - A tool for WLAN performance testing
(Master thesis, 2007)Wireless Interface for Sensors and Actuators (WISA) is ABB's proprietary wireless protocol for industrial automation on the factory floor. It operates in the 2.4GHz ISM band. Wireless Local Area Networks (WLANs), which ... -
WISA vs. WLAN: Co-existence challenges: Analysis of frequency-hopping sequences
(Master thesis, 2007)Wireless Interface for Sensors and Actuators (WISA) is ABB s proprietary wireless protocol for industrial automation. It operates in the 2.4 GHz ISM band, as do nearly allWireless LAN systems. WISA does frequency-hopping ... -
Word Discovery from Unsegmented Speech
(Master thesis, 2020)Hensikten til denne oppgaven er å finne ord i sammenhengende tale ved hjelp av ikke-veiledet maskinlæring. Det ble testet med to metoder av latent faktoranalyse; Non-Negative Matrix Factorization (NNMF) og Beta Process ... -
Work-in-Progress: An agile approach to formative assessment in higher education
(Peer reviewed; Journal article, 2021)Formative assessment is part of a learning process in which the teacher continuously monitors students' learning and provides feedback intended to let students themselves reflect upon what they have learned and where they ... -
"World of NTNU": - et seriøst spill for rekrutterings og forskningshensikter
(Master thesis, 2010)Dette prosjektet startet som en videreutvikling av Håvard Richvold sin masteroppgave hvor han utviklet et seriøst spill ("serious game") for rekruttering på NTNU. Prosjektoppgaven startet med å designe et MMO, "massive ... -
Wraparound S-bånd antenne for rakett
(Bachelor thesis, 2004)Forsvarets forskningsinstitutt benytter i dag dyre, kommersielle antenner til bruk på testraketter. De har derfor et ønske om å kunne utvikle slike antenner selv for å spare store kostnader. Vår prosjektgruppe har i ... -
X-ray diffraction studies of InAs/GaAs heterostructures
(Master thesis, 2012)Intermediate band solar cells (IBSC) is a proposed new type of solar cell device that has an intermediate energy band in the band gap. One possible implementation of IBSCs is by using arrays of nano-sized semiconductor ... -
Yield improvements in anaerobic digestion of lignocellulosic feedstocks
(Peer reviewed; Journal article, 2020)The new EU bioenergy sustainability criteria demonstrate that bioenergy sustainability can be a challenge (Schlegel and Kaphengst, 2007). In 1990s, the energy crops were the main source for biogas production in Europa; ... -
Ytelse for multippel antenne teknikker i LTE
(Master thesis, 2011)This thesis is about doing test runs at an LTE base station at Telenor at Fornebu. The tests are performed to find out how good the systems work, and specifically for this thesis to explore the possibilities of spectral ... -
Zero Delay Joint Source Channel Coding for Multivariate Gaussian Sources over Orthogonal Gaussian Channels
(Journal article; Peer reviewed, 2013-05-31)Communication of a multivariate Gaussian source transmitted over orthogonal additive white Gaussian noise channels using delay-free joint source channel codes (JSCC) is studied in this paper. Two scenarios are considered: ... -
Zero-Emission Autonomous Ferries for Urban Water Transport: Cheaper, Cleaner Alternative to Bridges and Manned Vessels
(Journal article, 2019)Because water is an integral part of day-to-day life for humans, civilizations have generally flourished either in coastal areas or near river basins. Today, about 40% of the world?s population lives near a coast and many ... -
