A reduced-order through-flow program has been developed at the Lund Institute of Technology. The goal of the work was to develop and verify a program suitable for scientific studies of coaxial turbines. The program has built-in capability for multiple choked stages, and turbine cooling, as well as flexible modules for state, losses, deviation, and blockage. The code uses Matlab [trademark] as a pl
This book chapter introduces the reader to an anthology of reportage, essays, eulogies, poems, proclamations, drawings, photographs, letters and more from the most chaotic phase of China’s Cultural Revolution. Entitled A Heroes’ Register, it is one of no more than a handful of surviving self-documenting accounts by the ‘dictating masses’ themselves of the ‘dictatorship of the masses’, as the Maois
Eukaryotic protein kinases, containing a conserved catalytic domain, represent one of the largest superfamilies of the eukaryotic proteins and play distinct roles in cell signaling and diseases. Near completion of rat genome sequencing project enables the evaluation of a near complete set of rat protein kinases. Publicly accessible genetic sequence databases were searched for rat protein kinases,
Popular Abstract in Swedish Deformerbara speglar som används i teleskop är förhållandevis små med en diameter på 10-30 cm, med undantag av ett fåtal. Den största deformerbara spegeln som är integrerad i ett teleskop idag, har en diameter på 911 mm och återfinns i Large Binocular Telescope. I designen för E-ELT har en deformerbar spegel med en diameter på dryga 2 m inkluderats och GMT har ett antalIt is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. We have pursued a low-cost approach using force actuators connected to the back of the deformable mirror through suction
The internet has had an impact on public relations that goes well beyond significant adjustments in practice made in response to technological change. Mirroring the emergence of ”Web 2.0” platforms, the discipline is increasingly articulating its purpose and culture through discourse associated with social media. Concepts such as transparency, authenticity, conversation and engagement can be inext
A passive system is one that cannot produce energy, a property that naturally poses constraints on the system. A system on convolution form is fully described by its transfer function, and the class of Herglotz functions, holomorphic functions mapping the open upper half plane to the closed upper half plane, is closely related to the transfer functions of passive systems. Following a well-known re
The seventeenth century saw the culmination of what has traditionally been called “Lutheran Orthodoxy”. Earlier a rather underestimated period, the time of “Lutheran Orthodoxy” has started to attract a fairer share of attention within the concept of Confessional Culture (recently coined by Professor Dr. Thomas Kaufmann). An enormously important but sometimes slightly overlooked part of this cultur
A new method based on the mode matching technique and the finite element method (FEM) is presented. The method can handle a general thick frequency selective structure (FSS), that consists of an arbitraryn umber of aperture layers and dielectric layers. An aperture layer consists of a conducting plate with a periodic arrayof apertures. The order and the thickness of the layers can be arbitrary. The
Popular Abstract in Swedish Giftiga alger - kan man äta sånt?! En sammanfattning på svenska Varje sommar varna's vi för giftiga algblomningar i media. Rapporterna brukar ofta handla om havet men många insjöar, speciellt i Skåne, drabba's också av massförekomst av alger. Det är framför allt cyanobakterier, eller blå-gröna alger som de kallade's innan, som blir så många att de helt dominerar algsaMass development of cyanobacteria (blue-green algae) is common in many lakes and coastal waters worldwide as a result of an increased nutrient loading. These blooms of cyanobacteria are undesirable for several reasons; thick mats of algae and unpleasant odour reduces the recreational values, bad taste reduces the quality of drinking water and the potent toxins produced by some species of cyanobact
Popular Abstract in Swedish Arbetet med denna avhandling har handlat om hormon-känsligt lipas (HKL) och dess roll i β-cellerna, som producerar insulin och finns i bukspottskörteln. För att senare kunna beskriva vad vi har kommit fram till och vad det kan innebära, kommer jag först att kort beskriva HKL och sjukdomen diabetes. Hormon-känsligt lipas Hormon-känsligt lipas (HKL) är ett enzym, som fiHormone-sensitive lipase (HSL) is a key enzyme in fatty acid mobilization. It is acutely regulated by extracellular signals via reversible phosphorylation. In the recent past, the focus of type 2 diabetes research has moved towards the lipid component. Lipids interfere with glucose homeostasis in a multitude of ways; they can decrease insulin sensitivity of tissues and cause β-cell dysfunction. Co
The state of the art for large database object retrieval in images is based on quantizing descriptors of interest points into visual words. High similarity between matching image representations (as bags of words) is based upon the assumption that matched points in the two images end up in similar words in hard assignment or in similar representations in soft assignment techniques. In this paper w
The problem of controlling delayed systems has been widely studied in the control community. The Smith predictor (SP) scheme was the most famous and efficient technique to cope with this problem. Afterwards, robustness problems and those related to the control of integrating and unstable delayed processes were resolved. This work presents an interactive tool for studying and understanding the diff
In order to improve the forecasts of the impact of solar activity on the terrestrial environment on time scales longer than days, improved understanding and forecasts of the solar activity are needed. The first results of a new approach of modelling and forecasting solar activity are presented. Time series of solar activity indicators, such as sunspot number, group sunspot number, F10.7, E10.7, so
