This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

Metod och teori: Studien utfo?rs med kvalitativ metod i form av deltagande observation. Den so?ker da?rfo?r djup snarare a?n bredd. Studien baseras pa? teorier skapade av Goffman med fokus pa? social interaktion mellan akto?rer inom fa?ltet fo?r att synliggo?ra de fra?gor som a?r viktiga fo?r akto?rerna. Slutsats: En ovilja att reflektera kring pedagogiska fra?gor a?r inte ha?llbar i dagens skola.

Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).

I uppsatsen unders?ks vad som k?nnetecknar texter skrivna av nyanl?nda ungdomar inom spr?kintroduktion i relation till bed?mningsst?det Bygga svenska (BS). Utg?ngspunkten f?r analysen ?r elevernas skrivande i tv? genrer: ?tergivande och argumenterande. I dessa unders?ks grundl?ggande grammatisk spr?kbeh?rskning, utifr?n processbarhetsteorin, samt graden av skriftspr?klighet utifr?n f?rekomst av utbyggda nominalfraser och grammatiska metaforer (GM).

Den 7 december 2022 offentliggjorde Europeiska kommissionen ett f?rslag till direktiv om harmonisering av vissa delar av insolvenslagstiftningen inom EU:s medlemsstater. Initiativet ?r ett led i kommissionens arbete med att st?rka kapitalmarknadsunionen och har till syfte att fr?mja ekonomisk och finansiell integration inom unionen. Direktivf?rslaget inneh?ller flera nyheter till svensk konkurs- och rekonstruktionslagstiftning, bland annat inf?randet av s? kallade pre-pack-f?rfaranden.

Denna klassrumsstudie fokuserar hur matematiklärare lyssnar på sina elever. Två olika lärares lyss­nande har observerats i klassrummet. Interaktioner i klassrummet har spelats in, transkriberats och analyserats med fokus på lärares lyssnande i en fenomenografisk ansats. Ambitionen är att försöka karaktärisera lärares lyssnande. Ett lyssnande ramverk som utformats av Davis (1997) och Yackel et al.

The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

The purpose of this thesis is to examine how the public libraries work towards SFI (Swedish For Immigrants) based on the views of the overseeing librarians. To study this we have asked the following research questions:What distinguishes the public libraries? work towards SFI according to the responsible librarians? What distinguishes the communication between SFI teachers and the librarians according to the responsible librarians? What opinions are held by the librarians in regards to their work with SFI?We have used a semi structured interview method with seven librarians in charge of the activities with SFI at small and medium sized public libraries in a rural area of Sweden. The theoretical framework is composed of Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local public library profile and the authors? definition of collaboration.

The aim of this paperisto find out which plants the Cistercian monks might have cultivated in Sweden during the Middle Ages and which types of plants it would have been practical to grow inside or outside of the Cistercian monastery precinct. Archaeologicaland archaeobotanical studies have been consulted to find out which plants were available in Sweden during the Middle Ages. Examples, mainly from Scandinavia, but also from the continent, are used to show that the monasteries were large institutionsthat had to feed a large number of people and that there would not have been enough space to cultivate everything needed within the monastery precinct.Secondary sources have in the main been used to gather this information, except in the case of the Swedish monastery of Nydala where F-Topo, a database developed by the County Museum of Jönköping,has been used to analyse the amount of land and the types of properties owned by the monastery.The conclusion is that for practical reasons the monks would have cultivated plants that needed to be close at hand, that were rare or delicate, that could not be stored for long periods and that were used in small quantities within the monastery precinct. This would include medicinal plants, herbs for cooking and some vegetables like lettuce, spinach,and similar,that do not keep well. Most other items, grains, cabbages, root vegetables, peas and beans could equally well be cultivated outside the walls.

De fo?rsta a?ren pa? civilingenjo?rsutbildningen besta?r till stor del av matematik och utgo?r en viktig grund fo?r kommande kurser i utbildningen. I en studie fra?n Sveriges Ingenjo?rer uppma?rksammas det dessva?rre att genomstro?mningen pa? de inledande matematikkurserna a?r relativt la?g. Samtidigt observeras det att anva?ndandet av internetbaserad undervisning, sa? som videofo?rela?sningar, o?kat markant bland ingenjo?rsstudenter de senaste a?ren.I denna studie underso?ker vi hur studenter pa? medieteknikprogrammet pa? Kungliga Tekniska Ho?gskolan anva?nder sig av videofo?rela?sningar i sina matematikstudier.

Syftet med studien a?r att belysa hur elever med specifika la?s- och skrivsva?righeter/dyslexi upplever sina mo?jligheter att utveckla en sja?lvka?nnedom kring sitt eget la?rande. Studien har genomfo?rts som en kvalitativ studie da?r totalt sex ungdomar fra?n tre olika skolor har intervjuats. Tre av dem a?r elever pa? ho?gstadiet och tre pa? gymnasiet.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

Denna studie syftar till att underso?ka fo?rekomsten av estetiska uttrycksformer i ett urval av svenskla?rares undervisningsmaterial. Syftet a?r ocksa? att se i hur stor utstra?ckning som det estetiska fo?rekommer i relation till det som i uppsatsen bena?mns som det icke-estetiska, och vidare vill uppsatsen ocksa? underso?ka hur det estetiska skrivs fram och vilket va?rde det ges.Studien tar utga?ngspunkt fra?n John Deweys reformpedagogig, Gardners a?tta intelligenser samt Aristoteles kunskapsbegrepp techne och mimesis. Underso?kningen diskuteras utifra?n forskning som visar pa? kreativitetens och estetikens betydelse fo?r inla?rning i ljuset av forskning som talar om skolans tra?ningslogik och uppgiftskultur.Textanalys anva?nds som metodansats da?r 34 texter fra?n lektion.se analyserats.

Detta är ett arbete som visar utvecklingen hos lärare i ett arbetslag som under två terminer har arbetet med temaenheter i NTA-projektet. NTA, Naturvetenskap och Teknik för Alla, är ett projekt som skall locka elever till ett naturvetenskapligt in-tresse. I projektet finns handledning till läraren och all materiel som behövs för arbete under tio veckor med en temaenhet. Syftet med arbetet är att undersöka vilka förändringar som sker inom ett arbetslag när ett nytt koncept tas in i den naturvetenskapliga undervisning. Tidigare forskning visar att framtidens lärare måste vara flexibla och kunna planera undervisningen efter en målstyrd läroplan.
