On the feasibility of personal audio systems over a network of distributed loudspeakers
2018
Los sistemas de reproducción de audio personal se ocupan de la creación de zonas sonoras personales dentro de una habitación sin necesidad de utilizar auriculares. Estos sistemas utilizan un conjunto de altavoces y diseñan los filtros necesarios en cada altavoz con el fin de que la señal de audio deseada llegue a cada persona en la sala lo más libre de interferencias posible. Existen propuestas muy interesantes en la literatura que hacen uso de arrays circulares o lineales, pero en este trabajo estudiamos el problema considerando una red de altavoces distribuidos controlados por un conjunto de nodos acústicos, que pueden intercambiar información a través de una red. Enunciamos el modelo de …

Revisors holdning til digitalisering i revisjon : En studie om revisors holdninger til digitaliseringen, og hvordan disse påvirker implementeringen a…
2020
Master's thesis in Accounting and auditing (BE508) Temaet for masteroppgaven er revisors holdning til digitalisering i revisjon. Revisjonsbransjen har tradisjonelt vært preget av manuelle arbeidsoppgaver, som gjør bransjen perfekt posisjonert for digitalisering. De fire store revisjonsselskapene er allerede godt i gang med innføringen av nye verktøy som for eksempel RPA og SAF-T. På grunnlag av at digitalisering ikke er et nytt fenomen, fokuserte studien på hvilke faktorer som påvirker revisors holdninger til innføringen av digitaliserte verktøy og arbeidsmetoder. Formålet med masterutredningen var derfor å belyse hvordan revisor stiller seg til økt bruk av teknologiske nyvinninger, og hvor…
CUSHAW2-GPU: Empowering Faster Gapped Short-Read Alignment Using GPU Computing
2014
We present CUSHAW2-GPU to accelerate the CUSHAW2 algorithm using compute unified device architecture (CUDA)-enabled GPUs. Two critical GPU computing techniques, namely intertask hybrid CPU-GPU parallelism and tile-based Smith-Waterman map backtracking using CUDA, are investigated to facilitate fast alignments. By aligning both simulated and real reads to the human genome, our aligner yields comparable or better performance compared to BWA-SW, Bowtie2, and GEM. Furthermore, CUSHAW2-GPU with a Tesla K20c GPU achieves significant speedups over the multithreaded CUSHAW2, BWA-SW, Bowtie2, and GEM on the 12 cores of a high-end CPU for both single-end and paired-end alignment.
Det vanskelige foreldreskapet : en studie av foreldre som har deltatt på kurs til foreldre med barn i fosterhjem : deres egenopplevelse av sitt forel…
2007
Regionalt Fosterhjemsarbeid avd. Kristiansand, Barne-, ungdoms- og familieetaten i region Sør arrangerte et kurs til foreldre med barn i fosterhjem vinteren 2006. Studien Det vanskelige foreldreskapet er blitt til ved at Regionalt fosterhjemsarbeid i Bufetat, avd. Kristiansand henvendte seg til PRAXIS – Sør/ Høgskolen i Agder v/ Institutt for sosiologi, sosialt arbeid og velferdsfag og ba om bistand til en oppsummering av foreldrenes opplevelse av egensituasjon og hvordan de har opplevd å delta på kurset. Studiens problemstillinger er, Hvordan presenterer foreldre som har deltatt på kurs til foreldre med barn i fosterhjem sin situasjon? Hvordan presenterer foreldre med barn i fosterhjem sit…

Rapid transformation of inorganic to organic and plant-available phosphorous in soils of a glacier forefield
2012
Abstract Chemical weathering of rocks or sediments is extremely important for the generation of soils, for the evolution of landscape, and as a main source of inorganic nutrients for plant growth and therefore for life. Temporal trends in weathering mechanisms, plant succession and nutrients availability in cold environments can be successfully studied in soil chronosequences along a glacier forefield. In the present paper, this was carried out in the pro-glacial area of Morteratsch. Different forms of phosphorous in the soil, stream and spring water chemistry were investigated. Apatite constitutes the main source of P, but it occurs only as a minor accessory mineral phase in the granitic/g…
Exploring parallel capabilities of an innovative numerical method for recovering image velocity vectors field
2010
In this paper an efficient method devoted to estimate the velocity vectors field is investigated. The method is based on a quasi-interpolant operator and involves a large amount of computation. The operations characterizing the computational scheme are ideal for parallel processing because they are local, regular and repetitive. Therefore, the spatial parallelism of the process is studied to rapidly proceed in the computation on distributed multiprocessor systems. The process has shown to be synchronous, with good task balancing and requiring a small amount of data transfer.
Application based on dynamic reconfiguration of field-programmable gate arrays: JPEG 2000 arithmetic decoder
2005
This paper describes the implementation of a part of the JPEG 2000 algorithm (MQ decoder and arithmetic decoder) on a field-programmable gate array (FPGA) board by using dynamic reconfiguration. A comparison between static and dynamic reconfiguration is presented, and new analysis criteria (spatiotemporal efficiency, logic cost, and performance time) have been defined. The MQ decoder and arithmetic decoder are attractive for dynamic reconfiguration implementation in applications without parallel processing. This implementation is done on an architecture designed to study the dynamic reconfiguration of FPGAs: the ARDOISE architecture. The obtained implementation, based on four partial config…
