Supporting Release Planning of Quality Requirements: The Quality Performance Model

Popular Abstract in Swedish Kravhantering är en process för att identifiera, specificera, och underhålla krav för en produkt. Om du inte har rätt krav, spelar det ingen roll hur bra allt annat görs. Detta kan sluta med en perfekt utveckling av fel produkt som kunderna inte vill ha. I marknadsdriven kravhantering, där det inte finns en specifik kund, är strategisk releaseplanering en viktig processIn a competitive environment, as experienced by market-driven organizations, it is important to plan software product releases with time-to-market in mind. To increase the chances of market success, software products need to be released to the market, not only at the right time, but also with higher level of quality than the competitors' products. Thus quality requirements can be seen as a key com

Visualism in mathematics

Professor Don Ihde introduced the term ‗visualism‘ in his book Expanding Hermeneutics; Visualism in Science, from 1998. The introduction of the term aimed to the development of a hermeneutics of science focusing in ‗visualization‘ of mental contents as the typical bearer of scientific truth. Ihde proposes the expansion of hermeneutical studies to the field of technoscience making a phenomenologica

Pathways to the entrepreneurial university: towards a global convergence

This paper analyzes the transition to the entrepreneurial university as part of a broader shift to a knowledge-based economy, arising from a complex interplay between exogenous (top-down) and endogenous factors (bottom-up) of a more or less similar nature, combined in different ways in different countries. Drawing on the experience of four countries (US, Sweden, Japan and Brazil) with different in

Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?

Popular Abstract in English What is common between the science of physics and global politics? They both define power in terms of energy. Indeed, the uneven distribution of petroleum reserves has been one of the main reasons of social, political and economic problems worldwide. Even more worrying is the rapid increase in the levels of greenhouse gases in the atmosphere. This is mainly caused by ouCaldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. Due to its CO2-free combustion and high energy density, among other desirable properties, H2is touted as a fuel of the future. Biological H2 production b

Evaporation of methyl- and dimethyl-substituted malonic, succinic, glutaric and adipic acid particles at ambient temperatures

Vapor pressures of five methyl-substituted dicarboxylic acids are inferred from measurements of evaporation rates of sub-micron particles using the TDMA technique at ambient temperatures. Vapor pressures values are given. These vapor pressures are compared witha vailable literature data and withv apor pressures of the un-substituted acids. Our results demonstrate that molecular structure is import
