Clover (Trifolium spp) gamefields : forage production, utilization by ungulates and browsing on adjacent forest

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Konstruktion av maskin för Tillverkning av sågblad

The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.

Erfarenhetsåterföring :  

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

Risk för spridning av ogräsfrö med rötrester : en litteraturstudie

With an increasing production of biogas follows an increased amount of digestate. This could potentially be a valuable source of fertiliser with the destruction of weed seeds as a possible advantage. However, there have been some concerns regarding the product still containing viable seeds of weed. In this Bsc thesis the results of previous research on the fate of weed seeds in biogas production is summarized. It is also a comparison of research on the effect of similar processes such as silage, compost or animal passage on seeds. The purpose of this is to evaluate risks of spreading viable seeds, potentially problematic species and perhaps to find out how to eliminate the risks. The literature review revealed that previous research mainly indicates low risks regarding many of the tested weed species, but not all studies show the same result, therefore extended research on the subject is desirable.

LUT ? En metod för systemutveckling med lean software development

Traditionell systemutveckling präglas ofta av långa utvecklingsprocesser och en oförmåga attmöta förändrade behov från kunden. Problematik med buggar i mjukvaran och förskjutnadeadlines uppstår kontinuerligt och leder till högre kostnader för företag.För att komma till rätta med dessa problem behövs en systemutvecklingsprocess som belyserproblem direkt när de uppstår och därmed tvingar de inblandade till reflektion över processensom skapar problemen vilket belyser de verkliga bakomliggande orsakerna. Låg kvalitet påmjukvara är ofta ett symptom på djupare organisatoriska problemEtt synsätt som syftar till att möta dessa problem är lean software development. Synsättet harinspirerats av lean production som är en beskrivning av The Toyota Production system vilketi sin tur är det arbetssätt som har tillämpats av Toyota under flera decennier i den traditionellatillverkningen.Mary och Tom Poppendieck har beskrivit sju principer och 22 tankeverktyg som kananvändas för att skapa en metod för lean software development. Studien visar vilka styrkoroch problem som lean software development och lean production beskriver generellt samtvilka styrkor och problem som finns avseende beskrivning av Poppendieck's principer ochtankeverktyg i synnerhet.

Värdeflödesanalys på Saab Training Systems i Huskvarna

Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.

Fruktkvalitet inom äppelodlingen : en studie av och för Äppelriket Österlen

The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality. The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.

Ett tv-formats utformning mot publicering på webben: Skall television utvecklas, anpassas och förändras utifrån sin publik?

Watching television (TV) has been given a new meaning, you don?t have to book a specific time, a specific date if you don?t want to miss the program you were planning to see. In Sweden now days we can watch TV in lot of different ways, whenever we choose to do so. In this thesis I attempt to explain and document the process of shaping a tvformat, the development and adaptation to a time when the TV medium is in a change. Plus a look at how the television audiences relate to their use of it.

Drivkrafter bakom den totala faktorproduktivitetens utveckling på regional nivå : En fallstudie på de svenska FA-regionerna under perioden 1990 ? 2005

Production requires the input of capital and labour. Hence, economic growth can be assumed to follow from increased levels of these two factors. Policies aimed at increasing production may consequently successfully be focused on facilitating the accumulation of capital and labour. However, even when an economy has managed to reach the same quantities of input factors as a more prosperous neighbour, the level of the production might still differ. The explanation of this lies in what economists refers to as expression embracing the characteristics of the input factors and the conditions in which they operate.In this thesis a calculation of total factor productivity is carried out, using existing data on the Swedish FA-regions between 1990 and 2005 and the method the economist Robert Solow in the 1950?s.

Hur tillverkande företag med distributörer kan förbättra sin marknadsföring av standardiserade produkter : En fallstudie inom ABB Low Voltage Products

Marknaden för industriella distributörer har upplevt stora förändringar under de senaste decennierna. Trots att industribolag nu har större möjligheter att sälja direkt via internet har distributörerna generellt sett stärkt sin position av flera anledningar. Forskningen har emellertid förespråkat att det är starka samarbeten som skapar värde i distributionskanalen. I huvudsak har detta påvisats med kvantitativa studier och forskare har därför efterfrågat kvalitativa ansatser.Delvis med målet att fylla detta forskningsgap utfördes en fallstudie om ABB Low Voltage Products distributörsförsäljning av produktkategori Pilot Devices, som bland annat innefattar tryckknappar. Pilot Devices valdes eftersom de är typiska distributörsprodukter i flera avseenden.

100 % svenskt foder till mjölkkor :

As for today, a large quantity of protein feeds is imported from other countries to be used in the Swedish dairy production. The main import is soya from Brazil. The soya-production in Brazil results in negative consequences for the natural environment in the area, and the long transport of the feeds requires a lot of energy. The organic dairy production in Sweden is, with the highest probability going to be forced to use 100 % organic feed to the cows in the year 2005, due to new EU-rules. These are some of the causes why there are reasons to look closer at the possibilities to feed Swedish cows with only Swedish feeds. In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding with only KRAV-approved feeds.

Aktivering av en dissolvingmassa med enzymer före en konventionell viskosprocess

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

Energianalys av Lavalverkstaden : Siemens Industrial Turbomachinery

Det svenska elpriset har under de senaste åren stigit kraftigt vilket inneburit avsevärt högre energikostnader för många företag. Siemens Industrial Turbomachinery i Finspång är en av dessa och har under en längre tid sett hur energianvändningen ökar för varje år, framförallt på grund av en allt intensivare produktion. Företaget vill därför se över energianvändningen i verksamheten. En energikartläggning och åtgärdsförslag av den största produktionsbyggnaden på området, Lavalverkstaden, är ett steg i den riktningen. Energikartläggningen har i grunden baserats på mätningar för att få en översiktlig bild över hur energianvändningen ser ut. Det sker genom att dela in energianvändningen i enhetsprocesser.

Vinster med björkinblandning i granbestånd i syfte att höja markens pH-värde

The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done. We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden. The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.

Industrial WLAN

WLAN i form av standarden IEEE 802.11 används inte i större utsträckning i industriell miljö. Vi undersöker hur pass protokollet kan användas för datakommunikation i sådan miljö med avseende på störningskänslighet och datorkraftsbehov, i form av en empirisk undersökning. Dessa undersökningar har utförts på en industri med de tre vanligaste standarderna IEEE 802.11b/g/n. Syftet med denna uppsats är att kontrollera vad som stör signalerna samt om den nyaste standarden 802.11n har något nytt som kan revolutionera inriktningen. Tester och undersökningar har visat att 802.11b och 802.11n är bäst när det gäller signalstyrka med störningskällor i omgivningen.
