Variations on the Evidence-Based Timeline Retrospective Method A Comparison of Two Cases

Project retrospectives can be a powerful tool for process improvement through obtaining new insights. However pure experience-based reflections may lead to incorrect conclusions. Our method, evidence-based timeline retrospectives (EBTR), mitigates this risk by providing a pre-generated timeline that visualises project history based on evidence rather than relying on subjective opinions and biased

The Stollberg ore field - petrography, lithogeochemistry, mineral chemistry, and ore formation

Popular Abstract in Swedish Denna studie har gått ut på att relatera litogeo- kemin (= kemin i bergarter) kring Stollbergs järn- och sulfidmalmsfält i Bergslagen till mineralogi och geologisk utveckling. Bergarterna kring Stollberg, liksom kring nästan alla andra järn- och sulfidmalmer (Cu, Pb, Zn) i Bergslagen, utgörs av vulkaniska bildningar. De vulkaniska bergarterna och tillhörande malmer bilThe Paleoproterozoic Fe-Pb-Zn-Mn(-Ag) Stollberg deposit is situated in the Bergslagen region of south-central Sweden. 6.65 Mt of sphalerite, galena and manganiferous skarn magnetite ore occur as disseminations and semi-massive to massive ore bodies hosted by volcanogenic sediments and carbonate rocks. Field relations, mineralogy and geochemistry suggest that the felsic volcanic rocks at Stoll- be

Problems and Solutions for Microprocessor Protection of Series Compensated Lines

Protection of systems with series compensated lines is considered to be one of the most difficult tasks for relay manufacturers and utility engineers. Protection and control of surrounding circuit elements, particularly transmission line protection, needs to be adapted to the variations introduced by these devices. Fixed series capacitors and thyristor controlled devices introduce harmonics and no
