En app för smartare måltidsplanering
This thesis is based on design theory about how to build an application for the mobile platform, a scientific analysis and an application for grocery shopping and meal planning. The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.
Allsidig rörelsekompetens hos barn och ungdomar : En kartläggning av skolelevers funktionella motorik
Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.

Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.
Motivation och läsförståelse : En studie av korrelationen mellan motivationen till att läsa och läsförståelsen hos elever i tredje ring på gymnasiet
This essay, called Motivation and reading comprehension, is a study of the correlation between the motivation to read and the reading comprehension of Swedish students in their final year of school before university level, meaning that they are eighteen or nineteen years old, sometimes more.The relation between the identity of the individual and the learning process has been a matter of scientific interest for some time, and this essay works in that tradition by investigating the connection between how pupils regard reading and how well developed their ability to decode text is.The reading comprehension is measured through a test that consists of a text from the Swedish epic by Vilhelm Moberg, Invandrarna, where the reader at certain intervals throughout the text is asked to mark the correct word from a choice of three. This test has been used and evaluated extensively by Per Fröjd, who has found that the results are reliable and useful.To measure the motivation to read I?ve constructed a survey to be answered before taking the reading test. It focuses on three different parts of reading motivation that are noted as the most important ones by Ivar Bråten. These are the feeling of joy and interest for reading, the goal to acquire knowledge of a specific subject, and the expectations that you have on yourself as a reader.Results show a weak or non-existent correlation between the two factors for the whole of the subjects, but once those who have a first language other than Swedish are removed the correlation becomes significant.
Utveckling och normering av ett stavningstest för vuxna (STAVUX)
Syftet med denna studie var att utveckla och normera ett logopediskt stavningstest för vuxna., då det idag saknas ett sådant test. Det framtagna testet bestod till en början av en orddel som innehöll 80 ord i varierande svårighetsgrad, utvalda för att representera svenskans olika stavningskombinationer. Vidare fanns en del med 80 nonord, konstruerade för att följa svenskans ljudmässiga uppbyggnad. 146 deltagare från 18 ? 94 år deltog i normeringen av testet.
Barns upplevelser av rörelse : -en intervjustudie med sex- och sjuåringar
In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.
En Modell av SOA för Agila Organisationer
In a dynamic and unpredictable reality, either rigid structures or silo architectures areappropriate ways to organize an agile organization. This thesis enlightens these relationsbetween Service Oriented Architecture (SOA) and an organization who acts in a varied andconstantly changing business environment. In other words, this thesis enlightens the question:?How suitable is SOA to organize the enterprise who will meet a constantly changing andheterogenic business environment?.The thesis presents a model where an efficient organization must be agile to be able to actquickly in the business environments with constantly changing desires, needs, expectations,desires etc. According to the same model a Service Oriented Architecture organizes theenterprise elements such as processes, resources, competences, responsibilities, informationsystems etc.
Styrsystem : För en forskningsutrustning
The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.
Effektiv och underhållssäker lagring av medicinsk data
Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..
Rein tension measures as indicator of horse - rider communication
The purpose of this study was to gather knowledge about the functioning of the rein tension meter and test it for future studies of match and mismatch between rider and horse. We looked specifically into the possibilities to use a rein-tension meter to determine the quality of cooperation between horse and rider. We examined whether a rider shows a specific tension pattern and also if certain patterns could be recognised for a specific horse. During the study, a manual with pictures and text was written to support the practical use of the meter. The manual describes in a simple way the first steps in the installation and use of the meter.

Utvecklingen av röstigenkänningsprogram under en treårsperiod
Detta kandidatarbete är utarbetat på Blekinge Tekniska Högskola under våren
2002. I utredningen har vi jämfört röstigenkänningsprogram under en
treårsperiod, program från 1999 och program från 2002.
1999 års test visade på programvaror med lång träningstid, enkla gränssnitt,
stor känslighet för bakgrundsljud och låg användbarhet. Vid arbetsstart
förväntade vi oss inte att hitta någon större förändring i användbarheten hos
dessa program 2002, då röstigenkänningsprogram inte verkar ha stor
användarskara.
Utifrån följande hypotes har vi genomfört arbetet: Vi vill med vår undersökning
bevisa att användbarheten inom röstigenkänningsteknologi inte har förbättrats
under perioden 1999-2002. Vi har för avsikt att med hjälp av test utförda på
program och demoversioner bevisa vår hypotes. I enighet med bifogad
testspecifikation har vi utfört testerna.
Många företag har utvecklat sina produkter och gjort dem bättre.
