?Var är du?? En studie om virtuella kollaborativa designprocesser i en studiemiljö
The design process of an interaction design student is mostly collaborative and computer oriented. Based on this, it?s hard to believe that we have not yet found a tool that will facilitate our needs. With this in mind, which elements do we need to promote collaboration in a virtual design process?
This thesis will include design processes, collaboration, creativity and virtual awareness, amongst others.
Utveckling av OBD-II-gränssnitt för fjärrdiagnostik av fordon
This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.
Genomisk selektion inom köttraser
Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.
Mätning av dynamiskt tryck med piezoresistiva tryckgivare på roterande objekt
The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signaltransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.
Skjuvhållfasthet och deformationsegenskaper för Uppsalalera med CRS och standardödometer
Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.
Neuropsykologisk studie av benign barnepilepsi med centrotemporala spikes
Benign Childhood Epilepsy with Centrotemporal Spikes - BCECTS is a common neurological syndrome but the possible cognitive effects are still relatively unknown. In the study 12 children with the diagnose BCECTS, 9 boys and 3 girls between the ages of 5,5 and 13,5 years, were examined. An extensive battery of neuropsychological tests were administered. The results indicates normal cognitive functioning as compared to the normal population, with one exception; an aspect of attention. But the results also indicate several negatively effected performances when compared to the cognitive g-factor of each child.
Metodik för resistenstest i renkavle : en studie om herbicidresistens; mekanismer, detektion och åtgärder
Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.
Undersökning av potentiella probiotiska organismer i tarmmikroflora hos häst med speciell hänsyn till Lactobacillus spp. :
The aim of this study was to isolate and identify Lactobacillus species indigenous to the gastrointestinal microflora of Swedish horses. These lactobacilli are to be used as probiotic candidates in research concerning antibiotic-associated diarrhoea in horses.
Eight horses, age 6-10 years, were selected from a riding school for collection of faeces samples. Man Rogosa Sharp medium and gram staining were used for the selection of supposed lactobacilli. We could identify 33 isolates of supposed lactobacilli. With the use of API tests 22 of these 33 isolates could be identified.
Överreaktion på aktiemarknaden - Myt eller verklighet?
PurposeThe purpose of this paper is to assess whether the overreaction found in ?Does the Stock Market Overreact?? by DeBondt and Thaler still persists today, and by equivalence test if a trading strategy based upon these assumptions would generate abnormal returns. MethodThe research has been carried out by studies of the stocks that for a prior period of one year has over or underperformed their benchmark. The stocks used in my study are all part of S&P500 index, and the period of study runs from three to five overlapping years over the last twenty years. ResultsMy tests indicate that the type of overreaction proposed by DeBondt & Thaler still is present, at least considering the stocks that during the formation period were winners..
Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :
The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter.
The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.
Organisera mera : En studie i att utforma riktlinjer fo?r organisering av information i ett specialutformat anva?ndargra?nssnitt
I have in this thesis studied how guidelines for organizing information in a custom- made user interface could be made. Teletal is service with a special designed user interface were information is stored. The purpose of this study is to encourage a consistent organization, and management of information in a user interface. The methods used in this study are as follows ? qualitative interviews and two card-sorting tests, of which one was closed and the other open.
Link QualityControl (LQC) i GPRS/EGPRS
This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.
En slumpmässig vandring eller genomsnittlig återgång : Råder förutsägbarhet på Stockholmsbörsen?
This study has been conducted in order to determine the existence of predictability for the Stockholm stock exchange. With this purpose the random walk theory has been raised against the theory of mean reversion in order to determine which theory is the most substantial. Data has been collected from Nasdaq OMX Nordic and furtherly been processed using the statistical software EViews. Swedish listed companies? daily share values between 2000-2014 have been analyzed using two tests; an Augmented Dickey Fuller test and a Variance Ratio test.
Fysiologi och beteende hos golden retriever i hemmiljö och under en testsituation
To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.
