LMSim, cacheminnessimulator för utbildningssyfte
Cache simulator is a tool to increase the understanding of a cache memory. Therefore cache memory simulation is included in the course Computer Engineering IS1200 at the Royal Institution of Technology. The purpose of this project is to develop a cache memory simulator for education. The existing MipsIt and Mips Simulator which is currently used in IS1200 has been the main source of inspiration. This resulted in the development of the cache memory simulator LMSim.
Lean i akutsjukvården: Flödeseffektivisering och slöseriminimering ? en fallstudie av Sunderby sjukhus akutmottagning
På grund av en ökad befolkningsmängd och nya tekniker som gör fler sjuka går att bota ställs nya krav på svensk sjukvård. Sjukvården måste möta de nya kraven med ett bättre effektivare resursanvändande och där till krävs nya förbättringsmetoder. Med influenser från industriell tillverkning har sjukvården omarbetat lean production för att skapa ett universellt förbättringsverktyg som lämpar sig för vårdorganisationer. Verktyget kallas lean healthcare och är omdiskuterat och dess effekter tvetydiga. Att undersöka om och hur värdeflöden i en akutmottagnings triage, som innebär en prioritering efter patienters allvarlighetsgrad, kan effektiviseras med hjälp av ett flödesorienterat arbetssätt som lean.
Forskarservice vid Arbetarrörelsens arkiv och bibliotek : en dokumenthanteringsplan
We have produced a process mapping and from there developed a document management plan for the research service at the Labour Movement Archives and Library (ARAB) in Stockholm, Sweden. The project was conducted during five weeks in the spring of 2011 at ARAB and the resulting classification structure and document plan has been formulated and presented to the staff at a seminar. We found that the institution in some cases were suffering from an inadequate documentation in a number of the identified processes, and also in their records management and archiving. In this additional memorandum follows an analyzing discussion of activity-based document- and archive management, e-archives and process mapping. We have accordingly tried to standardize the process of research services and contribute to a more adequate document management within the institution.
Vattendragsrestaurering i teorin och fiskinventering i praktiken : en litteratur respektive metodstudie
Running water-pathways have played an important roll in Sweden and frequently been
manipulated. One profound change was made during the period of logging when
streams were cleared from obstacles as big boulders, sharp bends and side-streams.
Dams and different constructions gave control of the stream water and the streams
became channel-like with a homogen structure. This interference gave problems for
many fish populations and resulted in a shortage of feeding habitat, over-wintering
habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural
temperature fluctuations. Many of these historical changes of the watersheds are now
subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.
En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö
The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
Hantering av skadade styrstavar
The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.
Habitatpreferenser hos tjockskalig målarmussla (Unio crassus) med avseende på vattendjup och beskuggning.
The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.
Förbättringsarbete mot Lean Production på Tooling Support Halmstad AB
Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.

Applikationerna har konstruerats i utvecklingsverktyget Visual Basic och med GIS-programvarorna MapObjects och MapObjects Internet Map Server. Den första applikationen som tillverkades är helt HTML-baserad (HTML är ett språk som används för att konstruera sidor på internet), vilket betyder att den fungerar som vilken sida som helst på internet, bortsett från att den kräver att en kartserver alltid har igång kartan i applikationen. Den andra har konstruerats med ActiveX. ActiveX är ett tilläggsprogram som fungerar tillsammans flera utvecklingsverktyg bl.a.
Minskning av produkter i arbete på Volvo powertrain
For Swedish companies to compete with low wage countries, developments in theproduction industry moved towards streamlining the entire company. One of themost effective ways for a company to streamline their operations is to review theirproduction. All companies have processes in their production that add no value tothe product. In order to compete, they must be eliminated.The purpose of this report is to reduce work in process (WIP) in the flow ofbashus at Volvo Powertrain in Köping. The aim is also to try to find reasons whyVolvo Powertrain feel that they have problems with the storage principle First in-First Out (FIFO).To meet the objective, empirical studies were conducted at the company whilethe literature in the area was studied.
Förslag till placering av anläggningar för att förbättra vattenkvalitén i Tidan
Considering water quality, landuse and reducion of wetland area in the watershed of Tidan, areas witch are in need of constructions to improve the water quality are identified. Constructions are suggested to be located within the smaller streams in the watershed, so that the water is treated before it reaches the stream Tidan..
Statistisk kartläggning av dimma längs E4:an mellan Helsingborg och Jönköping
Fog is a small-scale weather phenomenon that are fascinating to people. However, the presence of fog in road traffic reduces the visibility and increases the risk of road accidents. By the Swedish Road Weather Information System (VViS), the safety on roads could ameliorate and road accidents caused by fog and other weather hazards could be prevented. Fog is however a complex and usually local phenomenon, why fog formation generally is not easy to predict. For that reason, a statistical mapping of fog, especially along a motorway with high traffic volumes, could be useful in planning to prevent road accidents.
