Configuration management for distributed development - practice and needs

Configuration management (CM) includes synchronizing and supporting developers in their common development and maintenance of a system. The rapid development of the Internet and time-to-market pressure affects software development. In order to utilize skilled personnel despite geographical location, groups of developers are now working all over the world on the development of common systems, a sit

Incidence and survival rates in Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome and polyarteritis nodosa.

Objective. To estimate the incidence of and survival rates for WG, microscopic polyangiitis (MPA), Churg-Strauss syndrome (CSS) and PAN within a defined population in southern Sweden. Methods. Cases were retrieved using hospital records and a serology database. All new cases of WG, MPA, CSS and PAN between 1997 and 2006 were included, provided they met pre-defined criteria, and were followed until

Sources of increase in lowermost stratospheric sulphurous and carbonaceous aerosol background concentrations during 1999-2008 derived from CARIBIC flights

This study focuses on sulphurous and carbonaceous aerosol, the major constituents of particulate matter in the lowermost stratosphere (LMS), based on in situ measurements from 1999 to 2008. Aerosol particles in the size range of 0.082 mm were collected monthly during intercontinental flights with the CARIBIC passenger aircraft, presenting the first long-term study on carbonaceous aerosol in the LM

Regionalizing short-term rainfall affected by topography in semiarid Tunisia

The characteristics of fine time-scale rainfall are important in many hydrological applications, such as infiltration, erosion and flooding. The spatial properties of such rainfall are, however, seldom known, especially for arid and semi-arid areas. A better knowledge of fine time-scale rainfall and also comparison with daily rainfall may yield possibilities for disaggregation. For this purpose, r

A Method of Assessing Acoustical Two-Port Properties of Earplugs

An experimental setup for objective measurements of high impedance objects in ducts, yielding the acoustical two-port properties of the object, is presented. The setup has been applied on earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent duplicating the outer ear of a person. The insertion loss

Meanings as Conceptual Structures

Cognitive semantics relates linguistic expressions to conceptual structures. The purpose of this paper is to present a framework for such a cognitive structure. As a preparation, Putnam's argument against intensional semantics as a theory of meaning is presented. Some of the main tenets of cognitive semantics as it has developed during the last years are outlined. The notion of a conceptual space

Allocation of Heterogeneous Resources of an IoT Device to Flexible Services

Internet of Things (IoT) devices can be equipped with multiple heterogeneous network interfaces. An overwhelmingly large amount of services may demand some or all of these interfaces’ available resources. Herein, we present a precise mathematical formulation of assigning services to interfaces with heterogeneous resources in one or more rounds. For reasonable instance sizes, the presented formulat

RADIATION DOSE MANAGEMENT IN CT, SPECT/CT AND PET/CT TECHNIQUES.

New imaging technologies utilising X rays and radiopharmaceuticals are continuously under development. The benefit of computed tomography (CT) has been so dramatic that there is a tendency to overuse it and not to place enough efforts into optimisation of the technique. It is also now more and more common to combine two imaging techniques into a single investigation, such as PET/CT and SPECT/CT-th

Quarternary structure and enzymological properties of the different hormone-sensitive lipase (HSL) isoforms.

BACKGROUND: Hormone-sensitive lipase (HSL) is a key enzyme in the mobilization of energy in the form of fatty acids from intracellular stores of neutral lipids. The enzyme has been shown to exist in different isoforms with different molecular masses (84 kDa, 89 kDa and 117 kDa) expressed in a tissue-dependent manner, where the predominant 84 kDa form in adipocytes is the most extensively studied.

Studies of inelastic cross-section in Rb(7S)+Rb(5S) collisions

The cross section sigma = (8+/-4) x 10(-15) cm(2) was determined for the Rb(7S) + Rb(5S) --> Rb(SD)+ Rb(5S) excitation energy transfer process, and the quenching cross section sigma(q) = (2 +/- 1) x 10(-14) cm(2) for the Rb(5D) state in collisions with ground state Rb atoms. Applying rubidium quasimolecular asymptotic potential curves at relatively large internuclear distances, a qualitative inter
