Tilt anisoplanatism and PSF retrieval in LGS MCAO using a predictive controller

It is shown how tilt anisoplanatism in laser-supported multi-conjugatedadaptive optics (MCAO) systems can be a) predicted from a prioriknowledge, b) compensated using additional natural guide stars (NGS),and c) estimated in real time from control loop data to allow PSFretrieval. As a consequence of the problems associated with retrievingatmospheric tip and tilt from laser guide star (LGS) measurem

Conflict of legal norms: definition and varieties

As emphasized by Jeremy Bentham and the analytical school, logical consistency is a requirement for rational legislation. For understanding consistency between norms, a logical scrutiny of normative conflicts is needed. In our paper, a framework for the fine structure of such conflicts is introduced and explained. “Normative conflict” is defined relative the framework and different types of confli

Tekniska möjligheter och sociala begränsningar - om äldre människors väg in i IT-samhället

Artikeln visar statistik och diskuterar möjligheterna och begränsningarna i äldres tillgänglighet till i IT-samhället under senare delen av 1990-talet. Resultatet från en intervjuundersökning (n=186)visar att äldre IT-användare kan kategoriseras i beroende, akriva och avancerade användare och att detta formas av tillgången, förmågan, förväntningarna, självbilden och dagliga restriktioner (sociala

Origin, release and functional significance of the novel gastric hormone ghrelin

Popular Abstract in Swedish Magsäcken är ett av kroppens största peptidhormon-producerande organ. Peptid-hormon härifrån är inte bara viktiga för att reglera olika fysiologiska funktioner i magsäcken t.ex. saltsyrasekretion och motilitet, utan också för andra funktioner i kroppen. Fortfarande vet vi mycket lite om de hormon som produceras i magsäcken. Några av de hormon man identifierat har okändaThe novel gastric hormone ghrelin was discovered by virtue of its ability to release growth hormone (GH) via interaction with the so-called GH-secretagogue receptor (GHS-R). Earlier only synthetic agents were known to bind with the GHS-R, hence, ghrelin is the first identified endogenous ligand. GHS-R occurs in the pituitary and hypothalamus but also in several peripheral tissues, suggesting the i

Real Java for Real Time -- Gain and Pain

The Java programming language, being a portable and safe object-oriented language, has gained much interest among embedded and real-time systems developers. However, standard Java implementations exhibit problems with performance, memory footprint, and predictability. The question is then, are these limitations inherent in the technology? Reviewing run-time aspects and the possibility to compile

Chemical abundances in cool metal rich disk dwarf stars

The present study of spectra of twelve metal-rich cool dwarf stars, carefully selected in order to cover a range of temperatures ( K), is a follow up on Feltzing & Gustafsson (1998) with the aim to understand the apparent over-ionization and anomalous elemental abundances found by them for the K dwarf stars in their sample. Our method of analysis employs synthetic spectra of the full spectrum

Konstellationer

Abstract in Undetermined Allt börjar med frågorna: Det eviga - betyder det något idag? Hur ser den akademiska friheten ut? När blir en samling människor en konstellation och vad innebär sådana sammanslutningar? Några av Sveriges främsta författare, forskare och kulturpersoner diskuterar. De talade orden räcker snart inte till. Istället leder dialogen till ett utbyte av texter. Iderika och egensinn

Nutrition in infancy - Clinical studies on dietary intake, metabolism and growth

Popular Abstract in Swedish Vad betyder näringsintaget för ämnesomsättning och tillväxt under barnets första år? Under första levnadshalvåret anses uppfödning med bröstmjölk ge spädbarnet ett fullvärdigt protein- och fettintag. Finns inte bröstmjölk att tillgå bör modersmjölksersättning (MME) ges istället. Bröstmjölk och/eller MME rekommenderas fram till ett års ålder tillsammans med barnmat, s kNutrition in infancy - Clinical studies on dietary intake, metabolism and growth Our aims were to try to determine an appropriate formula protein concentration to be used during the second half of infancy and to evaluate the effects on plasma lipids when breast milk was exchanged for formula and/or weaning foods. Both aspects were studied with special regard to the influence of traditional weanin

Towards a Taxonomy of Planning and Scheduling Methods in the Context of Construction Management.

Planning and scheduling are considered as one of the most difficult but most important processes from perspectives of project management. These processes involve implementation of a widerange of planning methods used by different organizations with various levels of planning knowledge. The planning methods for scheduling can be classified as traditional methods (e.g. line of balance, Gantt chart a

Paranormal Media

The paranormal has gone mainstream. Beliefs are on the rise, with almost half of the British population, and two thirds of Americans, claiming to believe in extra sensory perceptions and hauntings. Psychic magazines like Spirit and Destiny, television shows such as Fringe, Ghost Whisperer and Most Haunted, ghost-cams and e-poltergeists, bestselling books on mind, body and spirit, and magicians li

Abstract in Danish En flerstemmig fortolkning af fire kunstneres praksis og tænkemåde. Mellem Prousts romankunst, Ekelöfs og Thomsens digtning og Springsteens rocksprog er der, forskellene til trods, krydsende og forbundne mønstre at spore. Essaysamlingens hovedtema er spændingen mellem individets maskerader og forsøg på at komme til orde og værdighed.
