This paper focuses on usage modelling as a basis for both requirements engineering (RE) and testing, and investigates the possibility of integrating the two disciplines of use case modelling (UCM) and statistical usage testing (SUT). The paper investigates the conceptual framework for each discipline, and discusses how they can be integrated to form a seamless transition from requirements models t
Essä om Exorcisten (1973) - publikmottagandet, filmkritiken och eftermälet samt om den nya Director's Cut-versionen som fick biopremiär 2001.
[1] Pathfinder AVHRR NDVI data have been analyzed for the African Sahel to study recent trends in vegetation greenness. A strong increase in seasonal NDVI was observed over large areas in the Sahel during the period 1982-1999. The increase is interpreted as a vegetation recovery from the drought periods of the 1980's. Although strong shifts in satellite overpass times have led to shifting solar ze
Haemophilus influenzae is an important respiratory tract pathogen responsible for a variety of infections in humans. Encapsulated H. influenzae belongs to one of six serotypes (a-f), of which type b is the most virulent one causing serious and sometimes life-threatening diseases (e.g., epiglottitis, septicaemia and meningitis). In contrast, non-typeable H. influenzae (NTHi) accounts for the majori
Sulfation of all macromolecules entering the secretory pathway in higher organisms occurs in the Golgi and requires the high-energy sulfate donor adenosine 3'-phosphate 5'-phosphosulfate. Here we report the first molecular identification of a gene that encodes a transmembrane protein required to transport adenosine 3'-phosphate 5'-phosphosulfate from the cytosol into the Golgi lumen. Mutations in
A low-phase-noise low-phase-error 1.8 GHz quadrature CMOS VCO was presented. The VCO with three metal layers showed -140 dBc/Hz or less phase noise across an 18% tuning range while drawing 25 mA from a 2 V power supply. The VCO showed high phase-noise figure-of-merit and low phase-error.
The present study is concerned with the preparation and characterisation of PEO/clay nanocomposites via melt-extrusion. Two different matrix molar masses of PEO were investigated as well as various types of the Cloisite clay range. PEO/Cloisite Na+ nanocomposites give rise to intercalated structures displaying only a moderate improvement of the mechanical properties at higher clay concentrations,
Between 1970 and 1995, well over 200 directives dealing with environmental problems have been adopted by the European Community. The ambition in this study has been to understand the process whereby environmental concerns have been brought up on the Community agenda and how that agenda has subsequently been shaped. It is argued that by starting from a critical position in ecocentric and feminist t
In accordance with international data, non-Hodgkin's lymphomas (NHL) in the Southern Health Care Region of Sweden were more common in men than in women and there was an inreasing incidence for both genders in the 1980s and 1990s. A study of the years 1983 and 1992, i.e. the beginning and the end of a 10-year period, was carried out. Case records for 94% of all adults diagnosed in 1983 and 1992 (22
It is well known that one of the features of long-memory processes is that they tend to have what looks like trends and cycles. A consequence of this property is that it is difficult to distinguish a long-memory process from a nonstationary process. In this paper, we study the impact of the periodicity and trend on different methods for estimating the long-memory processes parameter d.
