Nivådiagnos med sensorfusion : Utveckling av koncept för nivåmätning i lutande tankar
Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.
Övervakning vid allmän anestesi och stående ingrepp på häst
The purpose of this literature study was to describe techniques for monitoring general anesthesia and standing chemical restraint in the horse. A number of various techniques and devices related to e.g. blood pressure measurement, blood gas analysis and pulse oximetry are defined, and finally their clinical relevance and reliability are discussed.
The equine patient is generally far more exposed to anesthesia-related risks than other smaller species. Complications such as hypotension and hypercapnia are commonly seen during general anesthesia. Thus, close monitoring is essentially performed by the veterinary nurse, whom is responsible for monitoring the anesthetized patient.
Naturvärden i en värmländsk bruksskog : en skogshistorisk studie av Åbengtshöjden/Bogranghöjden
In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite.
The aim of the study is to interpret the history of the forest in the area, i. e.
Rationalitet : En jämförande studie och analys av olika definitioner och användande av begreppet rationalitet i förhållande till moral standing
Jag ska i denna uppsats ta upp tre olika filosofers definitioner och användande av begreppet rationalitet och analysera, tolka och jämföra dessa. De filosofer jag har läst in mig på skiljer sig i det att de argumenterar för olika normativa filosofier. Jag har läst Kant som är deontolog, Singer som är utilitarist och Regan som är rättighetsteoretiker. Jag kommer att introducera och analysera varje enskild filosofs definition och användande för att sedan jämföra och söka efter likheter och skillnader. Jag kommer också att diskutera vad dessa skillnader och likheter kan bero på och vad det kan ge för resultat.
Utvärdering av produktionsrapporterad volym för contorta
The background to this study is that the forest company, Holmen, has found large discrepancies between harvested volume and the measured volume at the industry. Factors like bark features, breakage, double tops, bends and stem damages was noted, and all stems were measured manually. Hypothesis testing with the method "random in pairs" were used to examine whether the harvester measured values significantly differed from the manually measured.
The result of a properly calibrated harvester shows in average underestimation of the volume with Skogforsk Pine as a bark function. This means that the harvester isn´t the reason why the volume measured in the industry is lower, the fault is elsewhere. The study also indicates a need for a unique bark function for logepole pine..
Visualisering av hovleden hos häst med magnetresonanstomografi
Lameness localized to the hoof is a common problem in horses. Magnetic resonance imaging (MRI) as a diagnostic tool is becoming more common and is well suited for examination of the distal limb and the hoof capsule. Today there are two different methods of MRI where in one the horse is under general anesthesia and in the other the horse is standing and only sedated. In this study we have compared the visualization of the distal interphalangeal joint using these two methods in two different groups of horses with unknown clinical problems referred to two different equine hospitals. The width of the joint structures including thickness of joint cartilage and joint fluid and also the width of the dorsal pouch of the distal interphalangeal joint were measured.
Från gles skog och brokiga ungskogar till homogen produktionsskog : en skogshistorisk studie av Hällforsmarken under 1900-talet
The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.
Postningsoptimering vid sönderdelning av fura vid Säters Ångsåg :
The aim of this project is to optimise the sawing patterns used for sawing Scots pine at Säters Ångsåg AB. The thesis has a theoretical approach and does not claim to be fully applicable in a practical point of view.
The input used in this project is last year?s sales volumes and prices of sawn products. The input of the timber is collected from the database ?VIOL?.
Naturvårdsavsättningar vid avverkning på Orsa Besparingsskog
Orsa Besparingsskog has an aim to take nature considerations in relation to the harvested volume and area of the annual felling. Around 15 percent of the acreage and 10 percent of the volume should be set aside. It is important to keep close to those figures to avoid future negative effects on the long-term harvesting planning. The purpose of this study was to use laser scanning data to estimate those proportions.
The result showed that the proportion of conservation considerations in the ten selected objects in the study was significantly higher than the target of 15 percent of the acreage and 10 percent of the volume. The result showed a setting aside of 19 percent of the acreage and 17 percent of the volume.
Testikelmått och daglig spermieproduktion hos svenska halvblodshingstar :
Testicular measurements and daily sperm output (DSO) are important factors affecting reproductive capacity of stallions. In the present study testicular measurements of 10 Swedish half-blood stallions were determined (height, length, width and volume). Ejaculates were collected from each stallion once daily for 10 days to evaluate some important seminal characteristics: gel-free ejaculate volume, sperm concentration, percent progressively motile spermatozoa and total number of spermatozoa (TSN). The gel-free ejaculate volume was measured with a graduated cylinder, the sperm concentration was counted in a Bürker chamber, the sperm motility was estimated in a phase-contrast microscope and TSN was determined by multiplying the gel-free seminal volume by the sperm concentration. Testicular measurements were as follows (left and right testis): height 7,5 cm and 7,8 cm, length 10,6 cm and 10,8 cm, width 6,5 cm and 6,6 cm, volume 278,2 cm3 and 293,8 cm3, scrotal width 12,3 cm and total testicular volume 572,0 cm3 .
Utvärdering av mikrobiologiska provtagningsmetoder inom ölbryggningsprocessen :
The aim of this study was to establish knowledge about the most suitable substrate for cultivating different kinds of anaerobic beer spoilage bacteria in the brewing industry. During the study, two other aspects were investigated; if the sample volume affects the results and which anaerobic beer spoilage bacteria are present in the micro flora at the brewery. The method used was standard cultivation with four different substrates; Universal Beer Agar, Nachweismedium Bierschädliche Bakterien, Raka Ray and VLB S7-S. During the identification of bacteria in the micro flora, a method using PCR was used. None of the substrates showed a significant advantage over the others.
Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning
To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual Standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.
Planteringsförbandets inverkan på bildningen av kärnved hos tall (Pinus sylvestris L.) : en modellsimulering av planteringsförbandets inverkan?
The current state of knowledge indicates that there is more than one factor that initiates heartwood transition. This study supports its hypothesis on the theory that heartwood is formed by a fixed fraction of the annual growthring, 0,5 to 0,8 rings. To calculate heartwood volume modelings were carried out in four different pine stands with different spacings, 0,75, 1,25, 1,5 and three meters. The model indicates heartwood diameter (HWD) and is based on four explanatory variables, height (H), crown ratio (CR%), diameter breast height (DBH) and tree height (TH). The shifting plant spacing results in varying growth rate in the juvenile stage.
Utvärdering av flygbildstolkning för uppskattning av beståndsvariabler och åtgärdsförslag i ungskogar : en studie på Korsnäs Skog och Bergvik Skog AB i västra Dalarna
In Korsnäs district Dala Väst there were problems with information concerning their younger forests, mainly those in pre-thinning stage. They were divided into large, heterogeneous stands with often poor stand data quality. In 2006 an aerial photo interpretation of the young forests was conducted to fix these problems. Necessary information to get from the interpretation were silvicultural management suggestions, new stand delineation and new stand data. This thesis is supposed to evaluate the quality and usability of the interpreted data.
To evaluate the interpretation an objective control inventory was conducted in 60 stands, either through callipering or counting stems.
Effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på kvantitativa rörelsetester hos friska kvinnor
Bakgrund: Medvetenhet om kropp och rörelse nämns ofta som en viktig fakor i att öka prestationsförmåga, undvika skador, nå högre livskvalitet och förbätta sjukdomstillstånd. Det har länge funnits ambitioner att förbättra rörelse genom ökad medvetenhet. Feldenkraismetoden är en metod för att förbättra rörelse genom förhöjd rörelsemedvetenhet och är förenlig med nutida vetenskap men förhållandevis lite empirisk forskning stöder metodens effektivitet. De flesta tidigare studier har varit på någon form av dysfunktion och ofta subjektiv upplevelse snarare än objektiva värden. Det har varit svårt för Feldenkraispedagoger att finna rätt mätmetoder för att utvärdera metoden.Syfte: Studiens syfte är att utvärdera effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på rörelse hos friska personer genom kvantitativ mätning.Metod: Friska kvinnor i en experimentgrupp (n=4, 30±7 år) och en kontrollgrupp (n=4, 26±2 år) testades med fem kvantitativa rörelsetester; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test och upper quarter Y-balance test, innan och efter en intervention ledd av en auktoriserad Feldenkraispedagog där experimentgruppen genomgick tio träningsfällen enligt Feldenkraismetoden under fem veckors tid.Resultat: Signifikant förbättring (P?0,05) i förhållande till både förtest och kontrollgrupp sågs vid star excursion balance test för vänster ben.Slutsats: Träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden verkar kunna leda till förbättring i kvantitativt mätt rörelse hos friska kvinnor.
