Models of Surface Roughness with Applications in Paper Industry

This thesis comprises general parametric models for surface roughness. The models can be used in several technical and natural applications but are here only applied to the micro-structure of paper. In that application, earlier models are generalized and new models introduced. The different models are related to the scale of the roughness and by using different approaches, different roughness prop

Flexible Embedded Control Systems : Design and Implementation

Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. This thesis presents an interactive prototyping tool called

s-Process elements in the M supergiant alpha Ori

We present new results on a study of the weak s-process elemental abundances in the M supergiant alpha Ori (M2Iab). We have conducted the abundance analysis through comparison of synthetic with observed spectra in the two infrared spectral regions 0.7 - 1.1 mu m and 2.1 - 2.3 mu m, where the molecular and atomic line densities are less than in the optical region and where many of the relevant elem

Construction and performance of the PHENIX pad chambers

We present the Pad Chamber detector system in the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. The three station system provides space points along each track in the spectrometer arms at mid-rapidity and covers a total area of 88 m(2). Its main functions are to provide the track coordinate along the beam and to ensure reliable pattern recogniti

Saponification then GC for determination of Irganox 1010 and Irganox 1076 in a polymer matrix

A gas chromatographic method has been established for determination of Irganox 10 10 and 1076 after saponification. The analytes were saponified with methanolic potassium hydroxide, acidified with hydrochloric acid, and the solvent was removed by rotary evaporation. The dry residue was dissolved in xylene and analyzed by GC with flame-ionization detector (FID). Compounds were separated on a polar

Effect on Survival and Hospitalization of Initiating Treatment for Chronic Heart Failure With Bisoprolol Followed by Enalapril, as Compared With the Opposite Sequence. Results of the Randomized Cardiac Insufficiency Bisoprolol Study (CIBIS) III.

Background - In patients with chronic heart failure (CHF), a beta-blocker is generally added to a regimen containing an angiotensin-converting-enzyme ( ACE) inhibitor. It is unknown whether beta-blockade as initial therapy may be as useful. Methods and Results - We randomized 1010 patients with mild to moderate CHF and left ventricular ejection fraction

Structural information for nanocomposites from measured optical properties

This paper is concerned with the estimation of the volume fraction and the anisotropy of a two- component composite from measured bulk properties. An algorithm that takes into account that measurements have errors is developed. This algorithm is used to study data from experimental measurements for a nanocomposite with an unknown nanostructure. The dependence on the nanostructure is quantified in

Investigation of sera from various species by using lectin affinity arrays and scanning ellipsometry

Serum proteins of different species and of different human blood groups exhibit various protein glycosylation patterns. Sera from human, pig, sheep and guinea pig have been applied to a panel of eight different lectins immobilized on a gold wafer. The biorecognition has been evaluated with scanning ellipsometry and the two-dimensional matrices obtained have been treated with image analysis and MVD

The MUST-analysis and the Role of Politicians in CI

MUST (Macroeconomic Uncertainty Strategy) analysis can help identify the demand side of competitive intelligence. It is a key tool by which relevant economic variables can be identified for companies. It also provides sensitivity coefficients necessary to translate the company's different environmental scenarios into corporate cash flow and value. Government, it is argued, should support companies

Factors influencing organic carbon recycling and burial in Skagerrak sediments

Different factors influencing recycling and burial rates of organic carbon (OC) were investigated in the continental margin sediments of the Skagerrak (NE North Sea). Two different areas, one in the southern and one in the northeastern part of the Skagerrak were visited shortly after a spring bloom (March 1999) and in late summer (August 2000). Results suggested that: (1) Organic carbon oxidation

Biologer i arbetslivet - en alumni- och avnämarundersökning

I en enkätundersökning har biologer, examinerade under åren 1990-1999, besvarat frågor om färdighetsträningen i utbildningen och kompetenskraven i arbetslivet. Denna följdes av en intervjuundersökning med ett strategiskt urval av avnämare på chefspositioner och med personalansvar. Av alumnenkäten framgick att de som var mest nöjda med grundutbildningen i biologi var de som fortsatt till forskarutb

An optimization approach to multi-dimensional time domain acoustic inverse problems

An optimization approach to a multi-dimensional acoustic inverse problem in the time domain is considered. The density and/or the sound speed are reconstructed by minimizing an objective functional. By introducing dual functions and using the Gauss divergence theorem, the gradient of the objective functional is found as an explicit expression. The parameters are then reconstructed by an iterative
