The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study. The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

The free choice of upper secondary school?A study of the meaning of the information channels for the choice of upper secondary schoolAuthors: David Fridner & Rikard ZeilonMentor: Ingela WadbringQuestionnaire studyDate: 2008-08-11AbstractThe choice of upper secondary school is a very important choice, both for the school and for the ninth grader. In Göteborg, the free choice of upper secondary school has generated several new information channels apart from the traditional counselor, daily news and the acquaintance. Today it is harder than ever to reach the pupil through the constant media noise and new forms of communication such as events appear. The fight for each pupil gets more and more important every term and it has now become real big business.Today?s youth is imprinted by a growing individuality and everyone knows that equableness is something very important.

Tidigare forskning har visat att barn med typisk utveckling går från en visuell strategi till en fonologisk. Huruvida denna utveckling sker hos personer med utvecklingsstörning är oklart. De flesta forskare är överens om att dessa personer har en nedsättning i den fonologiska loopen. Om denna nedsättning beror på strukturella avvikelser eller utvecklingsförsening är forskarna inte eniga om. Det är även oklart var en eventuell strukturnedsättning skulle sitta.

In the spring of 2009 Silva Sweden AB was contacted for a collaboration within the scope of a MasterThesis project. The company had discussed the possibility to develop a device that monitors usermovement during different types of exercise. The objective of this Master Thesis has therefore been todevelop and design a multi training device that records the user?s physical performance during severalactivities. The purpose of the thesis project has been to use scientific methods for product development inorder to design a multi device that supplements Silva?s range of products.The project followed a product development process divided into four phases; Market Analysis, ConceptCreation, Concept Development and Construction.

I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.

Our employer Camatec Industriteknik AB gave us the assignments to increase theirs range of versions on Camcoil that is their own patent product. Camcoil is a capstan system that is used when steel band fabricated. Exist for example in production lines their steel band should be annealed. Our goal with this work is to come up with a completed production basis on a Camcoil for heavy industry. The basis should contain calculations, 3D-constructions, drawings and cost proposal on manufacturing and detail purchase.Demands on this project:1.

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Att investera rätt är en fråga som bekymrat de flesta någon gång i livet. När, var och hur ska det investeraras för att skapa god avkastningen på det satsade kapitalet? Sedan 80-talet har svenskens placeringar och aktivitet på aktiemarknaden vuxit explosionsartat. 1980 hade svenskarna 27,3 miljarder kronor sparande i aktier vilket har ökat till 686 miljarder 2008, ett gott tecken på den ökade aktiviteten på aktiemarknaden.Utöver den privata finansiella rådgivning bankerna erbjuder kan den privata investeraren ta del av aktieanalyser och rekommendationer. Många av dessa når allmänheten genom bland annat tidningar och internet som köp- och säljrekommendationer av aktier.

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

Utvecklingen inom järnvägssektorn går mot snabbare och mer effektiva transporter, dock begränsas utvecklingen av att det krävs nya och mer utvecklade spår och tåg för att uppnå det. Med dagens infrastruktur och tågmodeller är hastigheter på 200 km/h det maximala. Behovet att öka kapaciteten och införa höghastighetstrafik i Sverige utreds i nuläget. Med höghastighetstrafik avses hastigheter på minst 250 km/h. Banverket har som förvaltare av järnvägen ett sektorsansvar för miljön och således även buller.
