Fracture characterization at Valhall: Application of P-wave amplitude variation with offset and azimuth (AVOA) analysis to a 3D ocean-bottom data set

The delineation and characterization of fracturing is important in the successful exploitation of many hydrocarbon reservoirs. Such fracturing often occurs in preferentially aligned sets; if the fractures are of subseismic scale, this may result in seismic anisotropy. Thus, measurements of anisotropy from seismic data may be used to delineate fracture patterns and investigate their properties. Her

Childhood roots of women’s subjective well-being: The role of optimism

The focus of the study is on the importance of early optimism for adult subjective well-being (SWB). Only females were studied. Data from age 13 and age 43 were taken from the Swedish longitudinal research program Individual Development and Adaptation (IDA, Magnusson, 1988). We investigated the longitudinal relationship between early optimism and optimism at age 43, its mediation via positive and

Sustainable Energy Systems in Sweden

Abstract in Undetermined This paper describes the Swedish-Polish Sustainable Energy Platform, its background, purpose and goals, as well as the partnerships between Sweden and Poland to establish this initiative. The paper also outlines a project initiated by the Swedish-Polish Sustainable Energy Platform to describe and analyze sustainable energy systems in Sweden, particularly from the perspecti

Coopetitive Capabilities in a Standardization Setting

A stream of research has highlighted the variations in competitive dynamics where the aim of firm interaction can range from competition, in order to appropriate value from competitors, to cooperation with competitors for mutual benefit. This study develops a typology of coopetitive value creation-appropriation strategies in standardization settings and then outlines a framework of a coopetitive c

Realization of a floating-point A/D converter

A floating-point analog-to-digital converter (FP-ADC) with a linear architecture has been implemented using an amplifier network in front of a pipeline ADC. The amplifier network has outputs with binary weighted gains, each sampled separately. The signal with the proper gain is then converted in the ADC. This structure allows instant floating point exponent determination. The mismatches in the amp

Fluorescence Spectroscopy Applied to Microscopy and to Clinical Tumour Identification.

Fluorescence spectroscopy has been applied to clinical tumour detection and to rmcroscopy. The fluorescence properties of biological tissue have been investigated within two clinical projects in order to discriminate tumours from normal surrounding tissue. Clinical studies have been performed on brain tumours in collaboration with the Department of Neurosurgery in Linkoping, and on urinary bladde
