Sedimentation in a tropical, microtidal, wave-dominated coastal-plain estuary
1996
The Mono estuary is an infilled, microtidal estuary located on the wave-dominated Bight of Benin coast which is subject to very strong eastward longshore drift. The estuarine fill comprises a thick unit of lagoonal mud deposited in a ‘central basin’between upland fluvial deposits and estuary-mouth wave-tide deposits. This lagoonal fill is capped by organic-rich tidal flat mud. In addition to tidal flat mud, the superficial facies overlying the ‘central basin’fill include remnants of spits resting on transgressive/washover sand, an estuary-mouth association of beach, shoreface, flood-tidal delta and tidal inlet deposits, and a thin sheet of fluvial sediments deposited over tidal flat mud.

A resource-based view of green innovation as a strategic firm resource: Present status and future directions
2021
Green innovation could become a valuable firm resource for establishing competitive advantage while simultaneously contributing towards sustainable development; in other words, green innovation has the potential to address the dilemma between consuming available resources and preserving them for the future. However, there is a dearth of studies systematically examining the present structure and future scope of research on green innovation as a firm resource. Seeking to explain the sustainable development dilemma of green innovations through the theoretical perspective of the resource-based view of the firm, we address this gap with a comprehensive bibliometric analysis of 951 relevant artic…
Combining population genomics with demographic analyses highlights habitat patchiness and larval dispersal as determinants of connectivity in coastal…
2022
Gene flow shapes spatial genetic structure and the potential for local adaptation. Among marine animals with nonmigratory adults, the presence or absence of a pelagic larval stage is thought to be a key determinant in shaping gene flow and the genetic structure of populations. In addition, the spatial distribution of suitable habitats is expected to influence the distribution of biological populations and their connectivity patterns. We used whole genome sequencing to study demographic history and reduced representation (double-digest restriction associated DNA) sequencing data to analyse spatial genetic structure in broadnosed pipefish (Syngnathus typhle). Its main habitat is eelgrass beds…
Minimum detection limits and applications of proton and helium induced X-ray emission using transition-edge sensor array
2017
Abstract We have determined minimum detection limits, MDLs, for elements 14 ⩽ Z ⩽ 86 using a transition-edge sensor array, TES array, and as a comparison using an Amptek X-123SDD silicon drift detector, SDD. This was done using a 3 MeV proton beam and a 5.1 MeV helium beam. MDLs were determined for a thin film sample on top of C substrate, and for a bulk sample containing mostly Al. Due to the higher peak-to-background ratio, lower detection limits were obtainable using the TES array for most of the elements. However, for elements 30 ⩽ Z ⩽ 45 the performance of the TES array was not as good as the SDD performance. This is due to the limitations of the TES used at energies >10 keV. The great…
Nye innovative bedrifter på Agder
2014
Masteroppgave Innovasjon og kunnskapsutvikling ME 513 - Universitetet i Agder 2014 Etablering av innovative bedrifter er viktig for økonomisk vekst og for vekst i sysselsetting. I denne oppgaven har jeg studert nye innovative bedrifter på Agder, som er etablert i perioden 2009 til 2013. Jeg ønsket å studere dette temaet for å finne ut av hvem det er som er med på å løfte Agder- regionen «opp og frem». Populasjonen jeg har studert er bedrifter som har fått landsdekkende etablerertilskudd fra Innovasjon Norge i tidsrommet 2009 til 2013. Kravet for å få tildelt et slikt tilskudd er at bedriften er etablert på bakgrunn av en innovasjon. Gjennom oppgaven benytter jeg meg av stortingsmeldingens d…
Formation and growth of palladium nanoparticles inside porous poly(4-vinyl-pyridine) monitored by operando techniques: The role of different reducing…
2017
In this work we followed the formation of palladium nanoparticles, starting from palladium (II) acetate precursor, inside a poly(4-vinylpyridine-co-divinylbenzene) polymer in presence of different reducing agents. The formation and growth of palladium nanoparticles in presence of H-2 was followed as a function of temperature by simultaneous XANES-SAXS techniques, coupled with DRIFT spectroscopy in operando conditions. It was found that the pyridyl functional groups in the polymer plays a fundamental role in the stabilization of the palladium (II) acetate precursor, as well as in the stabilization of the palladium nanoparticles. The effect of a thermal treatment in alcohol (ethanol and 2-pro…
Intern kommunikasjon i Glencore Nikkelverk
2016
Masteroppgave samfunnskommunikasjon- Universitetet i Agder, 2016 Denne masteroppgaven omhandler intern kommunikasjon i Glencore Nikkelverk i Kristiansand. Fokuset er rettet mot interne kommunikasjonsmedier og mediebruk i avdelingene Nikkelelektrolysen og Kontrollrommet. Undersøkelsen omfatter i tillegg ansattes erfaringer med interne kommunikasjonsmedier og ansattes meninger om informasjon som gjelder sikkerhet og forbedringsarbeid. Nikkelverket jobber kontinuerlig med forbedringer som øker produktiviteten, samtidig er sikkerhet det viktigste bedriften fokuserer på hver dag. Bedriften benytter rundt 10 ulike medier for å formidle denne informasjonen til sine ansatte. Disse mediene brukes i …
Lean orientert effektivisering og automatisering av produksjon for små og mellomstore bedrifter
2014
Masteroppgave i industriell økonomi og teknologiledelse IND 590 Universitetet i Agder 2014 Den norske leverandørindustrien for sprøytestøping har vært inne i en god utvikling de siste par årene, dette til tross for økende konkurranse fra lavkostland. Den endelige hovedrapporten for grunnlaget av inntektsoppgjørene 2014, redegjort av 'Teknisk beregningsutvalg for inntektsoppgjørene' (TBU), peker på kunnskapsutvikling som en bærende forutsetning for konkurranseevne hos norsk industri (TBU, 2014). Et viktig bidrag for konkurranseevne vil være den norske samarbeidsmodellen2 og den skandinaviske arbeidslivskulturen. Den norske samarbeidsmodellen har mange likhetstrekk til Lean-tankegangen, spesi…
Node co-activations as a means of error detection : Towards fault-tolerant neural networks
2022
Context: Machine learning has proved an efficient tool, but the systems need tools to mitigate risks during runtime. One approach is fault tolerance: detecting and handling errors before they cause harm. Objective: This paper investigates whether rare co-activations – pairs of usually segregated nodes activating together – are indicative of problems in neural networks (NN). These could be used to detect concept drift and flagging untrustworthy predictions. Method: We trained four NNs. For each, we studied how often each pair of nodes activates together. In a separate test set, we counted how many rare co-activations occurred with each input, and grouped the inputs based on whether its class…
