Do better IR tools improve the accuracy of engineers’ traceability recovery?

Large-scale software development generates an ever-growing amount of information. Multiple research groups have proposed using approaches from the domain of information retrieval (IR) to recover traceability. Several enhancement strategies have been initially explored using the laboratory model of IR evaluation for performance assessment. We conducted a pilot experiment using printed candidate lis

Measuring and modelling plant area index in beech stands

For some beech (Fagus sylvatica L.) stands with different stand densities the plant area index (PAI) was measured by means of a Licor LAI-2000 plant canopy analyser. The stands are located on the slopes of a valley in south-west Germany and had been treated by different types of silvicultural management (heavy shelterwood felling, light shelterwood felling, control plot). The analyser was used (a)

On Cholecystokinin and Phospholipase A2 in Insulin Secretion - an Experimental Study With Reference to the Development of Diabetes

Popular Abstract in Swedish Diabetes är en kronisk ämnesomsättningsrubbning, med en förhöjd nivå av cirkulerande blodsocker som ett av dess första kännetecken. Sjukdomen bygger på det faktum att kroppens olika celler är beroende av hormonet insulin för att kunna ta emot och tillgodogöra sig det näringsgivande sockret glukos. Således, för att kunna bibehålla en normal blodsockernivå krävs två förutIn view of unsolved issues regarding cellular events underlying the adaptation of insulin secretion to insulin resistance, together with the observation that insulin secretion induced by the gastrointestinal hormone and neuropeptide cholecystokinin (CCK) is not solely explained by phospholipase C-protein kinase C (PLC-PKC) pathway activation, this study aimed at delineate mechanisms responsible fo

Kommunikation för naturvetare

Detta är en handbok i skriftlig och muntlig presentation som behandlar naturvetenskaplig kommunikation med olika målgrupper och i olika sammanhang: vetenskapligt skrivande, opposition och återkoppling, populärvetenskaplig presentation samt kommunikation i undervisningen. Boken riktar sig till studenter och yrkesverksamma inom de naturvetenskapliga ämnesområdena, och är tänkt som ett stöd för alla

This glossary was prepared under the guidance of Hans-Erik Nissen in collaboration with the authors of the papers in the monograph. It is a glossary of terms used in monograph Double Helix relationships in use and design of Informing Systems: Lessons to learn from phenomenology and hermeneutics

OldBeijing.net - a Chinese Virtual "Heimatmuseum"

China’s state-run archives offer some interesting surprises to students of history looking eastward from a European vantage point in 2006. Beijing’s Municipal Archive, for example, is something quite unlike what one might expect if all one knew were the archives of Eastern Europe’s now “former” communist states. Particularly noteworthy is the use of the internet as a tool of interactive communicat

Different Methods for Quark/Gluon Jet Classification on Real Data from the DELPHI detector

Different methods to separate quark jets from gluon jets have been investigated and tested on data from the DELPHI experiment. A test sample of gluon jets was selected from $bar{b}g$ threejet events where the two b-jets had been identified using a lifetime tag and a quark jet sample was obtained from $qar{q}gamma$ events where the photon was required to have a high energy and to be well separated
