Software faults: spreading, detection and costs

The paper considers, through modelling, how software faults are spread throughout the entire life-cycle of a large software product and how fault detection and correction processes will affect the spreading mechanism. The study is further enlarged to incorporate models for cost estimation. The models can be described as being of a qualitative rather than a quantitative nature, in that they highlig

The Abundance of the Future. A paraconsistent approach to Future Contingents

Supervaluationism holds that the future is undetermined, and as a consequence of this, statements about the future may be neither true nor false. In the present paper, we explore the novel and quite different view that the future is abundant: statements about the future do not lack truth-value, but may instead be glutty, that is both true and false. We will show that (1) the logic resulting from t

Determining link weight system under various objectives for OSPF networks using a Lagrangian relaxation-based approach

An important traffic engineering problem for OSPF networks is the determination of optimal link weights. Certainly, this depends on the traffic engineering objective. Regardless, often a variety of performance measures may be of interest to a network provider due to their impact on the network. In this paper, we consider different objectives and discuss how they impact the determination of the lin

Lung function in children born after foetal growth restriction and very preterm birth

Aims: To assess lung function at early school age in children delivered at very early gestation owing to intrauterine growth restriction and abnormal foetal blood flow (IUGR). Methods: Spirometry was performed at median age 8.4 (range 6.5-10.7) years in 31 children born preterm with IUGR (PT-IUGR) with a median (range) birth weight (BW) of 650 (395-976) g and median (range) gestational age 27 (24-

Joint statement of the European Association for the Study of Obesity and the European Society of Hypertension: obesity and difficult to treat arterial hypertension.

Obese patients are prone to arterial hypertension, require more antihypertensive medications, and have an increased risk of treatment-resistant arterial hypertension. Obesity-induced neurohumoral activation appears to be involved. The association between obesity and hypertension shows large inter-individual variability, likely through genetic mechanisms. Obesity affects overall cardiovascular and
