Several methods to detect faults have been developed in various fields, mainly in chemical and process engineering. However, minimal practical guidelines exist for their selection and application. This work presents an index that allows for evaluating monitoring and diagnosis performance of fault detection methods, which takes into account several characteristics, such as false alarms, false accep
A previously proposed model for non-stationary signals is extended in this contribution. The model consists of mul- tiple time-translated locally stationary processes. The opti- mal Ambiguity kernel for the process in mean-square-error sense is computed analytically and is used to estimate the time-frequency distribution. The performance of the kernel is compared with other commonly used kernels.
To assess the distribution of blood from the umbilical vein (UMV), inferior vena cava (IVC) and superior vena cava (SVC) to either side of the fetal lamb heart by using ultrasound enhanced contrast agent imaging. By injection of ultrasound contrast agents (UCA) in UMV, IVC or SVC, the blood from these vessels was tracked, as it then was highly echogenic. By evaluating the image intensity within th
Aim: The primary objective of this study was to describe demographics and end-of-life treatments of children with cancer at a government tertiary cancer center in India. Methods: A retrospective review was undertaken of medical charts of all children younger than 18 years, who died as inpatients while undergoing treatment at the pediatric oncology department between April and September 2016. Data
Quantitative evaluations are valuable in the strive for improvements and asserting quality. However, the field of Command & Control (C2) evaluations are hard to navigate, and it is difficult to find the correct measurement for a specific situation. A comprehensive Scoping Study was made concerning measurements of C2 performance and effectiveness. A lack of an existing appropriate framework for
A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NOX, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, has developed
Denna rapport utgör redovisning av ett arbete som LUCRAM (Lunds universitets centrum för riskanalys och riskhantering) har genomfört på uppdrag av Myndigheten för samhällsskydd och beredskap (MSB). Uppdraget heter ”Studie om föreskrifters inverkan på kommuners risk- och sårbarhetsanalyser avseende jämförbarhet och enhetlighet”. Inom detta uppdrag har LUCRAM genomfört en dokumentstudie av kommunala
A neural model with N interacting neurons is considered. A firing of neuron i delays the firing times of all other neurons by the same random variable theta((i)), and in isolation the firings of the neuron occur according to a renewal process with generic interarrival time Y-(i). The stationary distribution of the N-vector of inhibitions at a firing time is computed, and involves waiting distribut

In this article we take the classic meaning of exemplum as a point of departure to show how examples are marked and used in oral discourse on 'others'. The empirical material is a transcribed focus group interview with Swedish students talking about a trip to Warsaw. Examples may be marked in explicit ways but also in implicit ways. Some examples seem recognizable by their allusive nature, others
Whereas extant theorizing on inter-organizational relational dynamics has highlighted the importance of between-partner differences, we shift attention to within-partner differences. We explore how internal fragmentation – i.e., the existence of multiple coalitions within a partner organization, each with different interests and perspectives – influences the evolution of relational characteristics

Thrombotic microangiopathy can be caused by several conditions which are difficult to diagnose from the clinical presentation alone. Deficient enzyme activity of a newly-discovered enzyme, ADAMTS-13, can lead to thrombotic thrombocytopenic purpura (TTP). Lack of ADAMTS-13 activity causes increased concentrations of high molecular weight von Willebrand factor forms and increased platelet aggregatio
We demonstrate that exceptional points exist in fully transparent, optically "effectively" biaxial, anisotropic micro-cavities, fabricated using an uniaxial cavity material with its axis inclined to the Bragg mirror growth direction. This is similar to the existence of singular (optic) axes in absorbing biaxial crystals, but the lack of time reversal symmetry is mediated by the mode broadening, i.
Lung cancer (LC) generally lacks unique core symptoms or signs. However, there are a multitude of bodily sensations that are often non-specific, not easily understood, and many times initially not recognized as indicative of LC by the affected person, which often leads to late diagnosis. In this international qualitative study, we inductively analyzed retrospective accounts of 61 people diagnosed
Avhandlingen är en sammanläggning av fyra artiklar om universell utformning i praktiken. Att designa för alla människor är en vägledande princip som Sveriges riksdag och regering beslutat om som del av implementeringen av FN:s konvention om rättigheter för personer med funktionsnedsättning. Avhandlingen bidrar med kunskap om förståelse, genomförande och samskapande gällande universell utformning. The thesis is a compilation of four articles and deals with Universal design in practice. This concept for designing for all is according to the Swedish Parliament and Government a guiding principle for the society. It is part of the implementation of the UN Convention on the Rights of Persons with Disabilities. The thesis contributes with knowledge about the understanding, implementation and co-c
Background: Home oxygen therapy (HOT) improves survival in patients with hypoxaemic chronic respiratory disease. Most patients evaluated for HOT are former or active smokers. Oxygen accelerates combustion and smoking may increase the risk of burn injuries and fire hazards; therefore, it is considered a contraindication for HOT in many countries. However, there is variability in the practices and p
