Motivated by collaboration with a global spare parts service provider, we consider a two-echelon inventory system with multiple local warehouses, a so-called support warehouse, and a central warehouse with ample capacity. In case of stock-outs, the local warehouses can receive emergency shipments from the support warehouse or the central warehouse at an extra cost. The focus is on using informatio

This paper presents a study wherein computer supported visualization is used to design and enhance understanding of quality systems. The study attempts to discover if a quality system such as ISO 9000 can be visualized, and how the visualization should be designed in order to support continuous improvement. Three companies in southern Sweden have set up special groups (here called design groups) w

Popular Abstract in Swedish Föreliggande arbetes övergripande syfte är att visa på faktorer/begrepp viktiga för en motiverande grundskolemiljö med fokus på klassrummet då analysen baseras på läroplansmålsättningar. Mer differentierade och explicit uttryckta syften för detta arbete utgörs inledningsvis av att dels undersöka hur elever och skolledare uppfattar att skolan uppnått målen i läroplan förThe prime purpose of the work in hand is to present factors/concepts important in generating a motivating environment in our compulsory school system, with a focus on the classroom, the analysis being based on the goals stated in the national curriculum. Expressed in greater and more explicit detail, the purpose of this study was initially to a)investigate how pupils and school principals perceive

My paper begins with some brief observations on the existing literature on the Chinese Communist Party’s post-Mao reversal of so-called unjust, wrong, and false cases. The paper then proceeds to examine a noteworthy difference between the PRC case and transitional justice in other states where “the transitional” entailed a further shift in power from an ancien regime to an entirely new order (viz.

Experiments in social media have rapidly become an important method in social science. However, there are a number of methodological problems connected to this method. One of these is the fact that social media are dominated by a small number of information oligopolists such as Facebook, Twitter and Instagram. Since the service provider has control over the information and the algorithms that stru

The Arctic Ocean Expedition of 2001 (AOE-2001) to the central Arctic mostly north of latitude 85°N was conducted to study marine life forms and their products in water and ice, how their products may get into the air, the evolution of the particles produced, and their growth up to sizes large enough for activation into clouds. The expedition also investigated whether these naturally generated part

This thesis describes optical spectroscopy on III-V semiconductor nanowires. The nanowires were grown by metal-organic vapor phase epitaxy (MOVPE) and chemical beam epitaxy (CBE). Photoluminescence and photocurrent spectroscopy are used as tools to investigate issues such as the size of the band gap, the effects of surface states, and the charge carrier transport in core-shell nanowires. The band
