Kriminallitteraturen og det fremmede : en uhyggelig lesning av Kim Småges Solefall
2006
Masteroppgave i Nordisk språk og litteratur 2006 - Høgskolen i Agder, Kristiansand Formålet med denne oppgaven var å studere kriminallitteratur i et fremmed og uhyggelig perspektiv. Jeg ville finne ut om man finner fremmede og uhyggelige elementer i kriminallitteraturen, og hvilke konsekvenser det eventuelt ville få, for kriminallitteraturen som sjanger, og for leseren. I de første kapitlene har jeg prøvd å plassere kriminallitteraturen i en kontekst, det uhyggelige. Senere vil jeg benytte meg av disse teorier i en nærlesing av Solefall. Femte kapittel er en presentasjon av forfatter Kim Småge, og kapittel seks er introduksjon til primærverket i denne oppgaven, romanen Solefall. Sjuende kap…
Some geometric properties of disk algebras
2014
Abstract In this paper we study some geometrical properties of certain classes of uniform algebras, in particular the ball algebra A u ( B X ) of all uniformly continuous functions on the closed unit ball and holomorphic on the open unit ball of a complex Banach space X . We prove that A u ( B X ) has k -numerical index 1 for every k , the lushness and also the AHSP. Moreover, the disk algebra A ( D ) , and more in general any uniform algebra whose Choquet boundary has no isolated points, is proved to have the polynomial Daugavet property. Most of those properties are extended to the vector valued version A X of a uniform algebra A .
A characterization of the Schur property through the disk algebra
2017
[EN] In this paper we give a new characterization of when a Banach space E has the Schur property in terms of the disk algebra. We prove that E has the Schur property if and only if A(D, E) = A(D,E-w). (C) 2016 Elsevier Inc. All rights reserved.
The differences between distributed shared memory caching and proxy caching
2000
The authors discuss the similarities in caching between the extensively studied distributed shared memory systems and the emerging proxy systems. They believe that several of the techniques used in distributed shared memory systems can be adapted and applied to proxy systems.
Compact 20-pass thin-disk amplifier insensitive to thermal lensing
2019
We present a multi-pass amplifier which passively compensates for distortions of the spherical phase front occurring in the active medium. The design is based on the Fourier transform propagation which makes the output beam parameters insensitive to variation of thermal lens effects in the active medium. The realized system allows for 20 reflections on the active medium and delivers a small signal gain of 30 with M$^2$ = 1.16. Its novel geometry combining Fourier transform propagations with 4f-imaging stages as well as a compact array of adjustable mirrors allows for a layout with a footprint of 400 mm x 1000 mm.
Mellom fragment og totalitet : en lesning av Øystein Lønns roman Hirtshals Hirtshals med spesielt fokus på form, erkjennelse og identitet
2006
Masteroppgave i Nordisk språk og litteratur 2006 - Høgskolen i Agder, Kristiansand Romanens fortelleteknikk er hovedfokus i kapittel 2. Her forsøker jeg å applisere erkjennelses- og identitesaspektet på tekstens formale dimensjon. I denne delen av oppgaven ser vi hvordan den impliserte forfatteren kompliserer forståelsesprosessen ved sin tilbaketrukkethet. Fortelleren medierer situasjoner nøytralt, uten ytterligere forklaringer og vurderinger. Resultatet er en diskurs som ligner på fotografienes virkelighetsgjengivelse og filmens montasjeteknikk, og den mosaikken teksten skaper tvinger leseren inn i en aktiv deltakelse fordi sammenhengen ikke ligger ferdig fortolket. Kapitlet viser hvordan …
750 mW continuous-wave solid-state deep ultraviolet laser source at the 253.7 nm transition in mercury.
2007
A high-power continuous-wave coherent light source at 253.7 nm is described. It is based on a solid-state Yb:YAG disk laser with two successive frequency doubling stages and is capable of generating stable output powers of up to 750 mW. Spectroscopy of the 6 (1)S(0)-6 (3)P(1) transition of mercury has been demonstrated.
Excitation power dependence of the Purcell effect in photonic crystal microcavity lasers with quantum wires
2013
The Purcell effect dependence on the excitation power is studied in photonic crystal microcavity lasers embedding InAs/InP quantum wires. In the case of non-lasing modes, the Purcell effect has low dependence on the optical pumping, attributable to an exciton dynamics combining free and localized excitons. In the case of lasing modes, the influence of the stimulated emission makes ambiguous the determination of the Purcell factor. We have found that this ambiguity can be avoided by measuring the dependence of the decay time on the excitation power. These results provide insights in the determination of the Purcell factor in microcavity lasers. © 2013 AIP Publishing LLC.
Lone Star Stack: Architecture of a Disk-Based Archival System
2014
The need for huge storage systems rises with the ever growing creation of data. With growing capacities and shrinking prices, "write once read sometimes" workloads become more common. New data is constantly added, rarely updated or deleted, and every stored byte might be read at any time - a common pattern for digital archives or big data scenarios. We present the Lone Star Stack, a disk based archival storage system building block that is optimized for high reliability and energy efficiency. It provides a POSIX file system interface that uses flash based storage for write-offloading and metadata and the disk-based Lone Star RAID for user data storage. The RAID attempts to spin down disks a…
LoneStar RAID
2016
The need for huge storage archives rises with the ever growing creation of data. With today’s big data and data analytics applications, some of these huge archives become active in the sense that all stored data can be accessed at any time. Running and evolving these archives is a constant tradeoff between performance, capacity, and price. We present the LoneStar RAID, a disk-based storage architecture, which focuses on high reliability, low energy consumption, and cheap reads. It is designed for MAID systems with up to hundreds of disk drives per server and is optimized for “write once, read sometimes” workloads. We use dedicated data and parity disks, and export the data disks as individu…
