Extrem-/äventyrssport innanför gymnasieskolans väggar
Syftet med vår undersökning var att undersöka om extrem-/äventyrssport hade en plats i
kursen idrott och hälsa A. Vi valde att skicka ut förfrågningar till 20 skolor i Malmö och
grannkommunerna, av dessa fick vi svar från tio och endast fyra ville delta i undersökningen.
Detta gjorde att vår undersökning omfattar fyra intervjuer med utbildade idrottslärare på fyra
olika gymnasieskolor i sydvästra Skåne.
I vårt resultat kom vi fram till att tre av lärarna hade extrem-/äventyrssport vid ca fem
lektionstillfällen per termin, och en hade inga lektioner alls med denna typ av aktivitet. Det
var många faktorer som spelade in när lärarna beskrev varför de inte hade så många
lektionstillfällen med anknytning till extrem-/äventyrssport bland annat tid, resurser,
skaderisk, engagemang och förutsättningar i närmiljön. Alla lärare vi intervjuade hade en
positiv inställning till extrem-/äventyrssport i skolundervisningen och skulle gärna vilja få in
fler lektioner med denna form av aktivitet, eftersom det hjälper att stärka elevers självkänsla,
ger en allsidig träning och är ett bra verktyg för teambildning. Tre av dem såg det som väldigt
viktigt att idrottsundervisningen i skolan följde med i utvecklingen, anammade de nya
aktiviteter som ungdomar sysslar med utanför skolan och att extrem-/äventyrssport hade blivit
ett stort fenomen i samhället.
Inverkan av flisig krossballast på betong
Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Title: Bottleneck management through materials administration Course: 4FE05EAuthors: Mikael Karlsson and Johannes Mueller Examiner: Helena ForslundKey words: Bottleneck management, material management, process description, timber, proceduresPurpose: The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing mill to keep a continuous flow, and thereby minimizing the risk for production stops at LB-Hus. Part. 1: Identify and analyze the material management connected to the planing mill in order to identify problem areas.Part.2: Identify improvement potential in the material management connected to the planing mill. Part.3: Suggest improvements in the material management connected to the planing mill. Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions.Empirical foundation: Interviews carried out at LB-House, illustrated with the help of process maps and a description of each process. Conclusions: To work with the suggestions given and to follow clear procedures in all processes would result in a more efficient inventory management, it would also present a solution to the problem regarding the planing mill being a bottle neck.Suggestions for further research: Review and map the information flow from demand to production start.
Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods
Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

FÖRBÄTTRAD MONTERING OCH DESIGNAV BAGAGELUCKA
This thesis includes a mechanical engineering design work performed incollaboration between ÅF and Halmstad University. The work is done by FredyOlsson?s methods of Principle- and Primary Construction and David Ullman?stheories of Design for Assembly.The group was commissioned by ÅF to produce a concept to narrow down theassembly time of today?s luggage doors by reducing the numbers of adjustmentoptions. They also wanted it to be easier to mount the assembly by making itpossible to adjust the door in a closed position. Today luggage door takes, with its10 adjustment possibilities, around 4 hours each to assemble and ÅF wanted anassembly time around 10 minutes per door.Initially a preliminary study was made where the group began reviewing today'sconstruction and mounting of rails and doors on buses.
Binär matchning av bilder med hjälp av vektorer från deneuklidiska avståndstransformen
This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..
Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö
The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
Framtagning av prototyp för att läsa och dokumentera kundspecifikationer
To increase the quality in their products ABB is working towards a cleared order concept. That means that all customer specified options are to be known before they start with order calculations and construction. As it is today they use paper checklists to achieve this. One order may have several reactors, and for a reactor there can be several different alternatives. For each alternative a new checklist must be filled out.As of today all reading of the customer specification and checklist fill in with is done by hand by different persons, and sometimes the same data is read more than one time.

En studie av ett grupporganiserat lärande
The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.
