It is tempting to assume that Information Systems Development Methodology (ISDM) is clearly understood because it has attracted researchers across a range of research fields offering a rich set of descriptions and explanations of ISDM. Although there are considerable studies on ISDM, this paper argues that different disciplinary interests have resulted in fragmented assessments. Consequently, this

In this paper, we study the geometry problems of estimating camera pose with unknown focal length using combination of geometric primitives. We consider points, lines and also rich features such as quivers, i.e. points with one or more directions. We formulate the problems as polynomial systems where the constraints for different primitives are handled in a unified way. We develop efficient polyno

Reliable analytical methods are increasingly needed in the food and beverage industry for the determination of specific components (e.g. sugars, proteins, vitamins, fats) and for detecting and quantifying chemical contaminants such as pesticides, heavy metals, antibiotics, and pathogenic microorganisms. The need arises from numerous regulatory actions and increased consumer concern about food comp

Of 30 primary ankle fusions in patients with osteoarthrosis, 25 ankles underwent clinical evaluation by two independent observers. In 29 cases, two independent radiologists, unanimously found 26 ankles to be radiographically fused, and three not fused. The consistency between the two orthopaedic surgeons evaluations was somewhat lower. A complete consistency between the evaluations of all four obs

High-spin states have been studied in neutron-deficient Xe-114(54), populated through the Ni-58(Ni-58,2p) fusion-evaporation reaction at 230 MeV. The Gammasphere gamma-ray spectrometer has been used in conjunction with the Microball charged-particle detector in order to select evaporation residues of interest. The yrast band has been greatly extended to a tentative spin of 52 (h) over bar and show

There is a vast amount of normative literature on change, which primarily focuses on how to manage change in an efficient and successful manner. What actually happens when management attempt to put their plans into practice is more seldomly investigated. Moreover, the prevailing literature on change primarily takes a management perspective. Other organizational members are usually treated as suppo

Popular Abstract in English From everyday experience we know that water and oil do not mix. In the scientific language we say they phase separate from each other. This happens because a water molecule and an oil molecule are inherently incompatible, the former exhibiting a ‘polar’ character and the latter a ‘non-polar’ one. Water and oil molecules are small, meaning that they are made up of only The subject of this thesis is experimental investigation of self-assembly in solvent-free (ionic) macromolecular systems that contain block copolymer chains as the basic constituent component in combination with low molecular weight amphiphiles. In particular, especial attention is paid to study thoroughly a new class of block copolymer-based ionic supramolecules, named as Linear-b-AmphComb, that

Vi möter våld i någon form dagligen, om inte som ”offer” eller ”förövare”, så när vi läser tidningen, tittar på tv eller går på bio. Hela världen kan förefalla organiserad med utgångspunkt i våld. Med våld upprätthålls stater, grupphierarkier och individuella maktpositioner. Merparten av våldsutövarna är män liksom hälften av offren. Den andra hälften av offren är kvinnor och barn. Det här mönstre

Proton Exchange Membrane (PEM) fuel cell systems have been studied as the alternatives of the internal combustion engine systems. However, these systems are not appearing in daily life yet, due to the high cost, shortage of infrastructure, technical issues, etc. Concerning technical issues, water/thermal management is a critical one to keep high proton conductivity in the electrolyte membrane for

Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. The aim of this thesis was to develop ef

This paper introduces the design of a new multiphase clock generator with no feedback loop. A single-stage direct interpolation architecture is proposed. A 1/4 frequency divider and a short-circuit current suppression interpolator are developed to achieve the precise interpolation. The circuit has been fabricated in a standard 0.35 μm, 3.3 V CMOS process. The multiphase clock generator can operate

A variant of the compatrison theory of metaphor is put forward. The main points are (a) a theory of metaphor belongs to semantics, not pragmatics, (b) a metaphorical statement is a similarity statement, usually comparing descriptions of objects, (c) a metaphor is a constellation of words connected by a certain kind of relation - the metaphorical link, (d) metaphors are not necessarily asymmetric,
