From Bugs to Decision Support – Leveraging Historical Issue Reports in Software Evolution

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

Development and validation of the predicted heat strain model

Eight laboratories participated in a concerted research project on the assessment of hot working conditions. The objectives were, among others, to co-ordinate the work of the main European research teams in the field of thermal factors and to improve the methods available to assess the risks of heat disorders at the workplace, and in particular the “Required Sweat Rate” model as presented in Inter

Socioeconomic status, labour market connection, and self-rated psychological health: The role of social capital and economic stress.

AIMS: To investigate the association between socioeconomic status, unemployment and self-rated psychological health, taking economic stress and horizontal trust into account. Design/setting/participants/measurements: The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study with a 55% participation rate. A random sample was invited and 28,198 persons aged 18-80 partici

Non Franck-Condon effects in the photoionization of molecular nitrogen to the N+ A 2II state in the 19-34 eV photon energy region.

Photoionization to the N2+ A 2Πu state is studied using photoelectron spectroscopy. Experimentally, vibrational branching ratios for the v′=0–3 levels obtained for the first time in the 20–34 eV region, show strong non Franck–Condon effects around 22 eV. Using ab initio many body perturbation theory, branching ratios for ionization to the A 2Πu state are calculated. This study indicates that the F

The World Hypertension League: where now and where to in salt reduction.

High dietary salt is a leading risk for death and disability largely by causing increased blood pressure. Other associated health risks include gastric and renal cell cancers, osteoporosis, renal stones, and increased disease activity in multiple sclerosis, headache, increased body fat and Meniere's disease. The World Hypertension League (WHL) has prioritized advocacy for salt reduction. WHL resou

Molecular characterization of invasive and non-invasive Streptococcus pyogenes isolates from Romania.

In 2002, the Romanian National Reference Laboratory was invited to join the Strep-EURO project to study invasive Streptococcus pyogenes infections. During 2003 and 2004, a total of 33 isolates recovered from invasive disease were received from eight Romanian counties. For comparison, 102 isolates from non-invasive disease, as well as a collection of 12 old invasive strains (isolated between 1967 a

GAFCHROMIC FILM AS A FAST VISUAL INDICATOR OF RADIATION EXPOSURE OF FIRST RESPONDERS.

Three types of Gafchromic films have been studied to investigate their potential for use as a visually readable dosemeter for persons acting as first responders in connection with radiological or nuclear emergencies. The two most sensitive film types show a pronounced variation in sensitivity by photon energy and are therefore not suitable for use in cases of unknown exposures. The third film type

Patterns of multiple myeloma during the past 5 decades: stable incidence rates for all age groups in the population but rapidly changing age distribution in the clinic.

OBJECTIVE: To define age-adjusted incidence trends in multiple myeloma (MM) in a well-characterized population during a long period, given that some, but not all, studies have reported increasing MM incidence over time and that clinical experience from some centers suggests an increased incidence mainly in younger age groups. PATIENTS AND METHODS: We identified all patients (N=773) with MM diagnos

Essays on Multi-Level and Multi-Item Inventory Control

Popular Abstract in Swedish I många företag och organisationer är planering av inköp, produktion, lagerhållning och transporter av stor betydelse för lönsamheten. Inom tillverkningsindustrin är det till exempel vanligt att värdet på lager, förråd och produkter i arbete överstiger värdet av hela produktionssystemet inklusive maskiner och byggnader. Effektiv styrning av produktion och lagerhållning In many companies and organisations the planning and control of purchasing, production, inventory and transportation is of great importance. In a manufacturing industry it is not unusual that the value of the total stock of end products and parts in production is larger than the value of the production system itself with its machines and factory buildings. Efficient control of inventory and produc
