In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.

I takt med Försvarsmaktens ökade engagemang internationellt och det faktum att alla insatsförband inom Försvarsmakten ska kunna verka på alla konfliktnivåer och i en urban miljö kommer nya krav och behov på bekämpningsförmågan att uppstå avseende precisionsbekämpning.Med hjälp av ett GIS kopplat till EOI:et vid en insats i en urban miljö kan en rad vinster erhållas för att stödja artilleriet vad avser precisionsbekämpning. Exempel på sådana områden är: målverifiering, justering av målkoordinater, lägesuppfattning avseende målets närmiljö, redovisning och presentation av verkansområde inför en insats för dimensionering av verkan..

In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared. The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single disc coulter, while the Spirit drills have a double disc coulter. Various aspects were compared such as aggregate distribution, seed placement, emergence, crop yield and economic outcome.

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..

Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

Optimering är ett ständigt problem att brottas med som inom spelbranschen. Endatorgrafiker som arbetar med spel ska inte bara skapa så estetiskt tilltalandemodeller som möjligt utan måste även få dessa att fungera tillsammans med detekniska krav som ställs utav industrins spelmotorer och hårdvara.Tesselering och displacement mapping är ett exempel på industrins olikatekniker för att ge spel en mer realistisk rendering genom att förbättra siluetter,ge mer korrekta detaljer och samtidigt avbelasta tunga beräkningar från CPU tillGPU genom att utföra geometrins polygonhantering på grafikkortet.Tesselering och Displacement Mapping har börjat öppna upp nya möjligheterför hur moderna spel kan se ut och som datorgrafiker så måste du kunnaidentifiera när, var och hur dessa tekniker bör användas.Detta examensarbete går igenom modellering, bakning och användning avdisplacement mapping på tesselerade geometrier inom en rad av grafiskaanvändningsområden med hjälp av ett par enkla tester i hopp om att göra digsom läsare redo för att skapa realistiska modeller..

The agricultural plantingmachines are used just a few weeks every year. That means that the supply of service and spare parts have to be good to make the timeliness costs low at the agricultural hard working periods. The machines wear down successivly when they are used. The wear is harder on some parts than the others on a machine. Spare parts can be dicided into consumables.

This pilot study describes a therapy method for persons withBroca´s aphasia. This method is based on the mapping hypothesis (Schwartz,Saffran & Marin 1980). The mapping hypothesis is based on the assumptionthat agrammatism is caused by an inability to combine syntactic structurewith thematic roles. This study describes a combination of the therapymethod mentioned above and the Everyday life activities photo series (ELA,Stark 1992). The aim of the study was to investigate if therapy based on awritten sentence/picture format is a viable starting-point for future research.The therapy presented combined written sentences with pictures describingeveryday life activities.
