Informationsdesign i hemmets hjärta : Struktur och ordning i kök för personer med neuropsykiatriskt funktionshinder

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

Effekt av brand och bete p? uppkomst av ?rtartade v?xter i restaurerade betesmarker. En j?mf?rande studie

Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.

Analytisk dimensionering av räddningstjänst : fördjupad analys av insatsförmåga och täckningsgrad inom Räddningstjänsten Syd

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.

Diskussion om röjningsrösen : med teorier om gravrösen i fossil åkermark och skärvstenshögar

This paper aims to investigate the connection between clearance cairns and burial cairns. From this point of view I try to answer the questions why they are built in the same area and why these two different types of cairns are so similary constructed. Further I consider different theories about mounds of fire-cracked stones..

Utvärdering och implementering av automatiska farthållare i fordonssimulator

Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.

Implementation och utvärdering av trådintensiv simulator i Java, Jetlang och Erlang

Trådning är svårt att få så effektivt som möjligt och det är komplicerat att skriva kod för det. Det här examensarbetet beskriver en implementation och jämför sedan implementationerna. Utvärderingen av implementationerna i Java, Jetlang och Erlang avslöjar att Jetlang skalar bäst både när det gäller komplexitet och hårdvara. Erlang behöver minst extra kod för att hantera trådning. När det gäller många små körningar har även Erlang bäst prestanda men tappar försprånget snabbt när komplexiteten ökar..

Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion

This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Utva?rdering av mikrofoner fo?r ho?rselhja?lpmedel

Syftet med detta examensarbete var att underso?ka MEMS och elektretmikrofoner fo?r att finna vilken typ som la?mpar sig ba?st fo?r fo?retaget Comfort Audio AB och deras ho?rselhja?lpmedelsprodukter. Uto?ver detta underso?ktes mo?jligheter att kontrollera upptagningskarakteristik med hja?lp av en teknik vid namn end-fire.Resultaten har erha?llits genom att underso?ka ett antal elektroakustiska egenskaper hos olika mikrofoner, som sedan har ja?mfo?rts med respektive tillverkares tekniska specifikationer. Upptagningskarakteristiken har underso?kts genom konstruktion av en mikrofonuppsa?ttning da?r den summerade signalen underso?kts.

That result in a lot of work to prevent accidents. The risks with modern technology is very small but it can?t be eliminated.

Den livgivande elden och det livsviktiga bränslet : Bruket av eld och behovet av bränsle på mesolitiska och tidigneolitiska boplatser i Norrland.

Research on Stone Age hunters and gatherers in Norrland has been lively since the 1960s. Central to this research are questions about the organization of society, sedentariness, continuity and resource management. One central part of life in the taiga is the need for fire and fuel. This aspect has been little discussed in conjunction with the mentioned research questions. My goal is to show that the matter of fire and fuel is an important one that needs to be taken in to consideration when discussing Stone Age Norrland and hunter/gatherers.

Trädföryngring i låga gropar uppkomna vid brand i boreal naturskog :

This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees. In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.

Folkrätt och kärnvapen : Om tillämpningen av NPT som icke-spridning och nedrustningsavtal

To work in an unpredictable work environment requires communication that functions well. In every organization it?s important that employees receive information that is relevant yet not confusing. Due to that, our ambition with this study is to understand how rescue effort organizations communicate in meetings; and whether their communication is clear or not. Our subject for this case study is the Emergency Services in the region of Karlstad.

Gruppdynamik och social gemenskap inom fallskärmssporten : ett elevperspektiv

The aim of this study has been to examine what students within the sport of skydiving think about their education and the social spirit of the community. The purpose of the study is thereby to answer the study's aim through the following questions; how does group dynamics and social solidarity work within the skydiving community, how do the students feel about group dynamics and social solidarity within the skydiving community, and what factors makes the students feel included or respectively excluded from the spirit of the togetherness?The theoretical part of the study focuses on group dynamics and groups overall. Further on earlier research within adventure sports and skydiving regarding group dynamics and community spirit is presented. My survey is based on 35 interviews with skydiving students.The result shows that the community spirit within skydiving sports is described by the students as very special, unique, and strong among the members.

Datorsimulering av gruvlastare för funktionell testning

I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..

Safire : Unik brandvarnare med smart design för ökad säkerhet

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.
