Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Research shows that there is a lack of knowledge of adult students with ADHD. Most of all research focuses on children with ADHD in school. The purpose of this study was to gain a better understanding of how adult learners with ADHD experience academic studies related to cognitive difficulties, emotion, motivation, and their experience of SOC. The questions tried to determine how any cognitive difficulties and emotions are perceived, how students' motivation to study impacted and their experience of SOC based on studies in higher education. To answer the purpose and questions used qualitative interviews based on three students with ADHD using a hermeneutic method.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

This report deals with the theory and empirical evidence of how knowledge generated within a project is to be captured and shared with other projects and the surrounding organization, after the end of a project. A number of authors have highlighted knowledge management within a company as a key component in building a unique competitive advantage and knowledge should therefore be considered a very important resource within companies. The difficulties of ensuring that knowledge generated within a project can benefit other projects are many. The nature of the project form has been highlighted as one of the biggest problems, due to the fact that budget and time requirements often restrict the propensity to work with knowledge transfer. Other difficulties that this report highlights are in particular the lack of a knowledge sharing culture within the organizations, as well as human cognitive and psychological limitations and lack of tools design for knowledge transfer.

This thesis on the sustainable urban development has the intent to discuss the conservator?s position in alteration of the built environment. An essential component of the thesis consists of a case study in the form of an entry in an open architectural competition for the development of Furuset, an urban residential area in Norway. The thesis? discussion is based on two approaches to change and socio-economic transformations, considered being dominant within the heritage theory and practice: the production of ideas and great narratives and conservation as an instrumental tool.

The general objective of this qualitative study is to analyse and describe what people with psychiatric disabilities write on their blogs about their encounters with social workers. The questions the study is aiming to answer are: How do people with psychiatric disabilities describe their encounters with social workers? Do the informants describe instances of paternalism and advocacy? How do the informants describe their sense of meaningfulness, comprehensibility and manageability? The study is based on a theoretical framework in which empowerment and sense of coherence (SOC) are the key elements, along with the concepts of paternalism and advocacy as well as meaningfulness, comprehensibility and manageability. The research data was collected from blogs on to the blog forum Psykiatrin.blogg.se ? psykiatrins Robin Hood (meaning ?the Robin Hood of psychiatry?).

Due to the harsh competition among Swedish food retailers, in-store marketing is a crucial component in the stores marketing strategy. In an attempt to differentiate among its competitors, COOP Sweden has begun to use concave store shelves. Although the food retailing industry is one of the most studied, no research has been conducted on the concave store shelves. The objective of this study is to describe how these shelves effect the customer perception of the assortment, their experience of the store environment and their buying behavior. An S-O-R framework is used as an overall basis in order to outline the effects investigated in this paper.

This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.

Increasing innovation and entrepreneurship has been identified as a key target for sustained growth and welfare, both in Sweden and abroad. Therefore, many countries have recognized the need to equip students with entrepreneurship education and to integrate skills associated with entrepreneurship into the various curricula.To shed light on entrepreneurship education within business curricula, a case study focusing on the first two years of the Bachelor program at the Stockholm School of Economics (SSE) was conducted. The study was based on interviews with students, alumni and scholars with a background of entrepreneurship. Insights from respondents were compared with leading research on entrepreneurship education, to evaluate the program's approach.Primary findings from the qualitative analysis showed an overall lack of entrepreneurship education in the early stages of the program. Entrepreneurial "know-how" knowledge was an insufficient component of the SSE program and a barrier for why more students did not pursue a career in entrepreneurship.

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

According to international and national literacy studies (PISA, PIRLS) Swedish boys are inferior to Swedish girls when it comes to reading. There can be numerous reasons to that statement. One is that Swedish teachers require more knowledge about communication as an important component in literacy. In spite of this shortcoming, Swedish girls manage to gain sufficient literacy. Why is that? The aim of this survey was to examine if there were any differences between girls and boys regarding communication skills when they begin in school.The main questions taken in account were:Which differences and/or similarities in communication skills are discernible between boys and girls this particular preschool?How do boys and girls communicate with each other in different room contexts on this particular preschool?           To be able to answer the questions, I adopted observations and audio recordings from children aged five.

Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.

The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use. Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.
