Arkeologihund : En studie i experimentell arkeologi om möjligheten att använda hund som arkeologisk prospekteringsmetod för att lokalisera humanosteologiskt material.

In today?s archaeology there?s a growing need for non-invasive prospection methods. However there?s a methodological gap and what?s missing is a method for locating human bones. In this study a specially trained German shepherd is put through scientific tests determining how good the dog is at telling the different between the scent of human and animal bones.

Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

Stereoseende i realtid

In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

Glidytor och ytjämnhet med avseende på friktion och tätning

Gliding and sealing functions in Öhlins shock absorbing systems sets great demands onthe contacting surfaces. In this particular case, the bushings and the sealings on acylinder piston. The surface wanted is a surface with both low frictional forces and smallleakage. This study was done with the goals of investigating and determining existingsurfaces due to the frictional force and leakage. How can we in an easy mannerdescribe these?A number of ten front forks were part of a main study.

The allotment plot : osäkrande som designstrategi

During the spring semester of 2009 I have participated in what was to become the project The Allotment Plot; a collaboration between the Swedish University of Agriculture and the Wanås Foundation. As one of six students in landscape architecture I have experienced a group based learning process with the point of departure in the designing of an organic and experimental kitchen garden at Wanås, a sculpture park for contemporary art. The project came out as neither us nor any other of the people engaged could have guessed. What was meant to be a garden turned out to become an entire cultivation movement. As students, we have gained a lot of experience through praxis; experience that will be valuable for our future profession. The project has also opened up the possibility to question and reflect upon what our profession and education could or should be about. This thesis focuses on the role of communication and the production of communicative tools in design processes and landscape architectural practice. It discusses how communication may be used in an exploratory and ?un-securing? way, and how this may dislocate the professional role, especially in situations where the design action, as in the case of this study, demands a high degree of transdisciplinarity and collaboration. .

Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning

Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory. The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method. The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking. The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.

Unified Flow Sensor

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

Texturbestämning genom fält-, pipett- och hydrometermetoder :

Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

Utvärdering av substrat för biogasproduktion

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

Research on the power of customer involvement, and in particular recommendation is very resourceful. Many studies have mapped the reasons for why customers are willing to recommend, however they often ignore potential differences among brands and how that may affect these reasons. This study is built on a quantitative survey investigating how consumers interact with brands, depending on category affiliation. The categories used were Bhat and Reddy's symbolic and functional, consisting of three brands respectively where each brand represented a different product type.The evolvement of social media has also transformed the platform of recommendation from physical to virtual and changed the way people connect. Thus, taking the investigation further, potential differences between symbolic and functional brands was tested in different social media platforms.

Kan man räkna till 100, kan man mycket : Barns tankar, funderingar och förståelse kring matematik

This study was designed to describe and understand how children perceive and explain mathematical situations. During our work based training we have met several students who have been insecure in the subject of mathematics and therefore come to think that it's difficult and boring. The questions we have asked ourselves are why and how this insecurity occurs. In preschools around the country teachers actively worked to create opportunities for children to meet and discover mathematics. The question is whether the teachers are aware of how children perceive mathematics and how children think in mathematical situations. We chose to conduct a qualitative study using different methods of data collecting in order to approach the children's world.

Läsinlärning och läsinlärningsmetoder : En kvalitativ studie om verksamma lärares val av läsinlärningsmetoder för läsinlärning hos barn i klasserna Fk-3

This study centres on learning to read and methods for teaching reading skills. The aim is to provide a survey of the concept reading skills and the methods developed on the basis of different theories and the methods preferred when teaching children in primary school and why. The study is based on interviews with eight teachers who are working on a dailybasis teaching Swedish in preschool class or lower primary school. The result of my study is that the majority of teachers do not use a specific method, but rather combine several different methods, thus adapting instruction to each individual pupil. .
