This licentiate thesis, containing two papers, is in the field of biomedical signal processing with main focus on signal processing of the ECG in patients with atrial fibrillation (AF). The two papers deal with different aspects of characterization of the f waves during atrial fibrillation. In the fist paper several measures designed to extract features of the f waves are evaluated with respect to

Popular Abstract in Swedish Människors sätt att visualisera objekt bygger på en del underliggande principer som man kanske inte alltid reflekterar över. Det faktum att vi har just två ögon gör det till exempel möjligt för oss att avgöra på vilket avstånd ett objekt befinner sig. Detta kallas för parallaxeffekten. Kameror, som bara har ett "öga", saknar denna förmåga, vilket försvårar avbildande mäLaser sheet imaging, also known as planar laser imaging, is one of the most versatile optical imaging techniques known and is frequently applied in several different domains. It furthermore constitutes the basis for a variety of other 2D methods, in turn allowing visualization of e.g. velocity, particle size, species concentration and temperature. However, when applied on turbid, light scattering

Leucopatch is a leukocyte and platelet-rich fibrin patch that provides concentrated blood cells and signal substances to the surface of an ulcer. It is produced by centrifugation of the patient's own venous blood. The aim of this pilot multicentre cohort study was to evaluate effects of the leucocyte patch in patients with hard-to-heal diabetic foot ulcers (DFUs).

This correspondence investigates the asymptotic behavior of reduced-state ISI equalizers, based on the Ungerboeck and Forney observation models. It is shown that Ungerboeck-based equalizers can suffer from correct-path-loss (CPL) even in the noiseless regime. ISI conditions that lead to CPL are analytically derived and illustrated by examples.

How to make a workplace health promotion questionnaire process applicable, meaningful and sustainable Background In workplace health promotion, a questionnaire could be of great use. Unfortunately, fatigue regarding answering questionnaires has recently become greater than before. An action research approach could be a possible way of increasing employee participation. Aim This study reports an at

I ett examensarbete som nyligen avslutats på Byggnadsmaterial, Chalmers, har man tagit reda på vad aktörerna i byggbranschen vet om fuktdimensionering. I arbetet intervjuades ett flertal konsulter, entreprenörer och beställare om deras syn på fuktfrågor i byggandet.

OBJECTIVE: To develop a simple and robust assay suitable for fetal RHD screening in first-trimester pregnancy and to estimate the sensitivity and specificity of the test after its implementation in an unselected pregnant population. METHODS: Pregnant women attending their first antenatal visit were included, and fetal RHD determination was performed for all women who typed RhD-negative by routine

Human C1q deficiency is associated with systemic lupus erythematosus (SLE) and increased susceptibility to severe bacterial infections. These patients require extensive medical therapy and some develop treatment-resistant disease. Because C1q is produced by monocytes, it has been speculated that allogeneic hematopoietic stem cell transplantation (allo-HSCT) may cure this disorder.

In this article I argue that the Harry Potter series could function as a critique or commentary to the ordinary contemporary society. Rowling’s construction of the Wizard world bears resemblance to a distinct Other, which is frequently used by the tourist industry and various religious traditions. While the main purpose for the tourist industry to invoke a distinct Other lies in its promoting abil

This thesis is concerned with the subject of craft and technology and the intricate connection between man, his objects and society. When archaeologists study social and cultural structures and phenomena, it is understood that the objects have been created and crafted by people, but the weight of this fact is not always recognized. Acknowledging that we are always studying the material expression

BACKGROUND: The genes caspase-8 (CASP8) and caspase-10 (CASP10) functionally cooperate and play a key role in the initiation of apoptosis. Suppression of apoptosis is one of the major mechanisms underlying the origin and progression of cancer. Previous case-control studies have indicated that the polymorphisms CASP8 D302H and CASP10 V410I are associated with a reduced risk of breast cancer in the
