An Agile Systems Engineering Analysis of a University CubeSat Project Organization
(Peer reviewed; Journal article, 2021)University CubeSat projects become popular in recent decades, and face challenges that include both technical and sociotechnical aspects. However, these teams often lack the infrastructure and resources for having effective ... -
Aksellerering av nevrale nettverk for søkeordsdeteksjon på FPGA ved hjelp av Intel OpenVINO og Xilinx DNNDK
(Master thesis, 2019)Nevrale nettverk brukes i nesten alle enheter med talegjenkjenning, som blant annet Alexa fra Amazon og Siri fra Apple. Disse nettverkene må kunne klassifisere store ordforråd med så liten forsinkelse som mulig. Dette ... -
Aktivitetsbasert emneorganisering
(Peer reviewed; Journal article, 2021)I artikkelen deler vi våre første erfaringer med aktivitetsbasert emneorganisering som ble prøvd ut på et stort innføringsemne for sivilingeniørstudenter ved NTNU. Den grunnleggende ideen er at for å fremme studentaktiv ... -
Akustisk analyse av snorking
(Master thesis, 2007)I denne oppgaven har i hovedsak to teorier blitt undersøkt :1) er det mulig ved hjelp av ørepropper med høyttaler og mikrofon å detektere snorking og deretter spille tilbake lyder som får personen til å stoppe snorkingen, ... -
AlGaN Nanowires Grown on SiO2/Si (100) Using Graphene as a Buffer Layer
(Peer reviewed; Journal article, 2019)III-Nitride epitaxy is deeply dependent on the substrate and is difficult to grow on amorphous substrates because of the lattice mismatch limits. In this paper, graphene is employed as a buffer layer to assist AlGaN nanowire ... -
Algorithm/Architecture Co-optimisation Technique for Automatic Data Reduction of Wireless Read-Out in High-Density Electrode Arrays
(Journal article; Peer reviewed, 2018)High-density electrode arrays used to read out neural activity will soon surpass the limits of the amount of data that can be transferred within reasonable energy budgets. This is true for wired brain implants when the ... -
Alternative methods to generate a first-order directional microphone
(Master thesis, 2014)This thesis deals with the implementation and analysis of diferent methods to generate a first-order directional microphone for source location and noise measurement purposes. The methods analysed include a cardioid capsule, ... -
Aluminum-based contacts for use in GaSb-based diode lasers
(Journal article; Peer reviewed, 2016)Aluminum-based contacts could be a good alternative to conventional gold-based contacts for a number of GaSb-based devices. In this study, the use of some Al-based contacts in GaSb-based diode lasers was investigated via ... -
Ambient RF-energy harvesting at 900 MHz
(Master thesis, 2016)In this thesis a RF-energy harvesting system able to harvest ambient power at 900MHz(GSM band) is simulated. Especially the efficiency at low power is of interest (-19 to -23 dBm rectifier input). A rectifier and a boost ... -
Ambient-light Photoplethysmography: - How can I tell your pulse from looking at your face?
(Master thesis, 2012)This thesis is an attempt to explore certain aspects of the subject called non-contact, ambient-light photoplethysmography, where we hope to reveal benecialproperties the technique may have. We have a clear focus on technical ... -
Amplified ladder networks for time division multiplexing of fiber-optic sensors
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:68, Doctoral thesis, 2005)Large systems of fiber-optic sensors are suitable for a wide range of applications ranging from seismic surveying to health monitoring of concrete structures. Time division multiplexing of fiber-optic sensors in ladder ... -
Amplifier for optimal reflection Coefficient of ultrasound transducer: A study of op amp based circuits for ultrasound transducers, targeted for low reflection Coefficient, high gain, and low noise
(Master thesis, 2012)Reverberation is defined as equally-spaced, bright linear echoes resulting from reflection from specular-type interfaces. They are provoked by the acoustic Impedance change between the tissue and transducer front surface. ... -
An 11.0 bit ENOB, 9.8 fJ/conv.-step noise-shaping SAR ADC calibrated by least squares estimation
(Journal article; Peer reviewed, 2017)A noise-shaping SAR ADC implemented in 28 nm UTBB FDSOI is presented. A cascaded FIR-IIR loop filter topology is used, and implemented as an inverter-based switched-capacitor circuit. The loop filter also employs input ... -
An adaptive high-throughput edge detection filtering system using dynamic partial reconfiguration
