Abstract in UndeterminedRoot cause analysis (RCA) is a structured investigation of a problem to detect the causes that need to be prevented. We applied ARCA, an RCA method, to target problems of four medium-sized software companies and collected 648 causes of software engineering problems. Thereafter, we applied grounded theory to the causes to study their types and related process areas. We detec

Disease trend studies based on birth cohort analysis and serological studies indicate that recent generations have a higher prevalence of oncogenic Human Papilloma Virus (HPV) types, and are likely to be at higher risk of cancer than previous generations. This implies that prevention strategies to protect young populations from HPV-associated cancers need to be strengthened, and hence organized im

A clock-and-data precharged dynamic (CDPD) circuit technique in CMOS is presented. It gives a fast one-clock-cycle decision to multilevel logic and has small clock loads, low peak current, small area and low power-delay product. The technique is highly flexible in logic design. For the given example, a 324bit binary-lookahead-carry chain, the speed improvement can be as high as 40–50% compared to

In this paper we study (sigma,tau)-derivations on algebras from an abstract point of view. After some definitions and examples, we derive Leibniz type formulas and introduce a module structure on spaces of (sigma,tau)-derivations. Then we find all (sigma,tau)-derivations on unique factorization domains when sigma and tau are different endomorphisms. We also prove necessary equations for sigma-deri

Dynamics of commercial fish stocks are generally associated with fishing pressure and climate variability. Due to short time series, past studies of the relationships between fish stock dynamics and climate have mainly been restricted to the last few decades. Here we analyzed a century-long time series of plaice, cod and haddock from the Skagerrak-Kattegat, to assess the long-term influence of cli

Popular Abstract in English Bracings are structural components that assure the stability of the load bearing structures is maintained so as a desired level of load-carrying capacity of them is achieved. The present study as a whole involves investigations of either the temporary or permanent bracings that are often required during the construction phase of steel bridges. Current knowledge concerniA number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved. The present research concerned the performance

Objective. To evaluate the effects on neonatal morbidity of a regional change in induction policy for post-term pregnancy from 43(+0) to 42(+0) gestational weeks (GWs). Design and setting. Nationwide retrospective register study between 2000 and 2007. Population. All singleton pregnancies with a gestational age of >41(+2) GW (n= 119,198). Methods. All Swedish counties were divided into three group

During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical appli

This study was aimed at investigating the outcomes of an activity-based assessment (BIA) compared with standard assessment (SA) for evaluating clients undergoing psychiatric occupational therapy. Patients admitted to a psychiatric occupational therapy unit were randomized into the BIA or the SA assessment. The outcome indicators were (a) clients' satisfaction with the occupational therapy during t

The aim of this study was to investigate the prevalence of extended-spectrum beta-lactamase (ESBL)-producing bacteria in patients at various hospital wards and in a group of relatively healthy volunteers, in order to obtain greater knowledge on how common these bacterial strains are in hospital settings and in the general community. Participants (n = 427) were enrolled at a University Hospital and

Popular Abstract in Swedish Utvecklare i stora mjukvaruprojekt måste orientera sig i enorma informationslandskap. Brist på överblick innebär ett hårt slag mot produktiviteten. Mönster ifrån tidigare buggar kan guida framtida underhållsarbete.Software developers in large projects work in complex information landscapes and staying on top of all relevant software artifacts is an acknowledged challenge. As software systems often evolve over many years, a large number of issue reports is typically managed during the lifetime of a system, representing the units of work needed for its improvement, e.g., defects to fix, requested features, or
