Denne mastergradsoppgaven er en komparative studie av tre norske lærebøker ved R1-matematikk. Bakgrunnen for oppgaven er hvordan de forskjellige lærebøkene velger å fremstille deres matematiske teori og deres oppgaver til elevene. Oppgaven begrenser seg til å se på områdene algebra og funksjoner. Problemstillingen er: "Hvilke forskjeller og likheter er det mellom tre ulike lærebøkers presentasjon ...

Using data from electronic health records this thesis aims to model and analyse health care services provided to adult patients with chronic conditions. Two aspects of health care services, with unique aims, have been examined. The first aspect is related to the aim of investigating factors affecting the patients' self experienced quality of the health care encounters with regards to satisfaction, ...

In this thesis work we develop and apply EOS formulation to three scattering problems: two of them are 1D problems and one is 2D. The first chapter comprises EOS formulations and numerical implementation for 1D scattering problems. Also in this chapter we use different numerical methods to solve test problem and choose the most stable and accurate method for solving of the given 1D problems. ...

In summer 2013 the WADIS-1 sounding rocket campaign was conducted at the Andøya Space Center (ACS) in northern Norway (69 N, 16 E). Among other things, it addressed the question of the variability in mesosphere/lower thermosphere (MLT) turbulence, both in time and space. A unique feature of the WADIS project was multi-point turbulence sounding applying different measurement techniques including ...

Mellin kind statistics (MKS) is the framework which arises if the Fourier transform is replaced with the Mellin transform when computing the characteristic function from the probability density function. We may then proceed to retrieve logarithmic moments and cumulants, that have important applications in the analysis of heavy-tailed distribution models for nonnegative random variables. In this paper ...

Lungs sounds has been used as a diagnostic tool for centuries. The usefulness of listening to lung sounds, or pulmonary auscultation, as a definite diagnostic method has been diminished by advances in medical imaging such as chest X-Ray, but these advanced methods also bring a higher monetary and time cost. In addition, when the severity of pulmonary conditions changes, audible symptoms change ...

We derive and validate averaged solvent parameters for embedding potentials to be used in polarizable embedding quantum mechanics/molecular mechanics (QM/MM) molecular property calculations of solutes in organic solvents. The parameters are solvent-specific atom-centered partial charges and isotropic polarizabilities averaged over a large number of geometries of solvent molecules. The use ...

A more efficient and effective approach for detecting animal species in digital images is required. Every winter, the Climate-ecological Observatory for Arctic Tundra (COAT) project deploys several dozen camera traps in eastern Finnmark, Norway. These cameras capture large volumes of images that are used to study and document the impact of climate changes on animal populations. Currently, the images ...

It is still strangely difficult to backup and synchronize data. Cloud computing solves the problem by centralizing everything and letting someone else handle the backups. But what about situations with low connectivity or sensitive data? For this, software developers have an interesting distributed, decentralized, and partition-tolerant data storage system right at their fingertips: distributed ...

With the accelerated advances in sequencing technology the last decade, the field of metagenomics has progressed immensely. Sampling and sequencing of metagenomic data is now prevalent, and publicly available data sets from mundane soil and water environments to exotic niche habitats such as geothermal hot springs are readily available through sequence data repositories such as the European Nucleotide ...
