Prototypes of wind turbines of the megawatt class are to be built and tested starting from 2008 at the German offshore wind energy test site in the North Sea. To ensure a high operational reliability of future generations of offshore wind conversion systems (OWEC) with economically acceptable repair and maintenance efforts, comprehensive diagnosis and supervision concepts are required. Automatic m
This paper presents an integrated simulation-based methodology for considering the effects of weather on formwork removal times. An expert tool for estimating formwork removal times and weather data with high resolution are integrated into a discrete-event simulation model containing a process model of in-situ concrete wall operations. In addition, operational measures (denoted as curing strategie
Context: Dopamine agonists are the treatment of choice for prolactinomas and symptomatic idiopathic hyperprolactinemia. However, the optimal treatment strategy and treatment duration is not clear in all details. Objective: The aim of the study was to assess the effect of dopamine agonist withdrawal in patients with idiopathic hyperprolactinemia and prolactinomas. Data Sources: PubMed, the Cochrane
Autologous dermal fibroblasts may be useful in the treatment of diabetic skin wounds. We hypothesized that cultured fibroblasts or cultured keratinocytes would not only survive in a hyperglycemic wound environment but also enhance the rate of re-epithelialization. We previously developed a new porcine model of delayed cutaneous wound healing in the diabetic pig. Full thickness wounds were created
To find a controller that provides the maximal stability margin to an LTI system under rank-one perturbations is a quasiconvex problem. In the paper, the dual quasiconvex problem is obtained, using the convex duality arguments in the Hardy space H∞. It is shown that the dual problem can be viewed as minimization of a "length" of uncertainties that destabilize the system. Several examples establish
The concept of neutrophil activation and degranulation as important contributors to disease pathology in invasive group A streptococcal infections has recently been emphasized. This study focuses on two of the most severe streptococcal manifestations, toxic shock syndrome and necrotizing fasciitis, and the newly described proinflammatory molecule resistin, known to derive from adipocytes and monoc
An exact treatment of the van der Waals interaction between two spherical dielectric bodies possessing purely classical degrees of freedom is presented. The spheres are described by multipole expansions of their fluctuating charge distributions, and the correlation between the fluctuations are taken into account using classical electrostatics and statistical mechanics. The presented approach avoid
The aim of the present study was to analyse the importance for non-typeable Haemophilus influenzae (NTHi) isolated from patients with sepsis (invasive isolates) compared to nasopharyngeal isolates from patients with upper respiratory tract infection to resist the complement-mediated attack in human serum and to correlate this to disease severity. We in detail studied and characterized cases of inv
We have investigated the possibility of using the 2.45 GHz ISM band for communication between binaural hearing aids. The small size of a modern hearing aid makes it necessary to miniaturize the antennas to make this feasible. Two different types of hearing aid placements have been investigated: in the outer ear and in the ear canal. Both put strict demands on the size of the antenna, which have be
Background-Although the heritability of atrial fibrillation/atrial flutter (AF/AFl) has been determined, the familial risk in multiplex families is unclear. The main aim of this nationwide study was to determine the familial risk of AF/AFl in multiplex families. Methods and Results-We examined the familial risk of AF/AFl in the entire Swedish population. We linked Multigeneration Register data on
Infections frequently consist of more than one strain of a given pathogen. Experiments have shown that co-infecting strains often compete, so that the infection intensity of each strain in mixed infections is lower than in single strain infections. Such within-host competition can have important epidemiological and evolutionary consequences. However, the extent of competition has rarely been inves
This work shows a unique possibility of visualizing the exponential intensity decay due to light extinction, when laser radiation propagates through a homogeneous scattering medium. This observation implies that the extracted intensity mostly originates from single scattering events. The filtering of this single light scattering intensity is performed by means of a single-phase structured illumina
To find approximate solutions to initial value problems (IVPs) one can use a wide range of numerical methods. A special group of IVPs referred to as stiff, can be numerically solved by a chain of methods, beginning with an implicit method then Newton's method and last, General minimal residual (GMRES). For GMRES to be more time-efficient, we need to apply a preconditioner to the system of equa
The interest of religion in the academia of history and the history of ideas has held an unobtrusive and modest position during modernity. Often, religion and its influences, was regarded as something waning, something that was about to disappear. Instead science would become the foremost guiding light upon which most historians would focus their gaze. This essay aims to examine how article-author
