Kommunikation mellan två medium

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

Bluetooth-implementation för Netbiter EC350

In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment. When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented. The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values. The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal.

Skriv- och läsundervisning i år 1 : En pilotstudie utifrån Aristoteles kunskapsformer

AbstractThis work is a pilot study intended to show what an experienced teacher of Swedish in first grade teaches and how she teaches. A further aim is to test methods for the analysis of Aristotle?s forms of knowledge in order to elucidate the teaching of reading and writing. As regards theory, the study proceeds from rhetoric and its doctrine of forms of knowledge according to which the whole in communication consists of episteme, techne and phronesis. The methods involve analysing the content of the communication and analysing speech acts, rhetorical figures and paralinguistic expressions.

Light or Voice ? make your choice! : Plocktekniker för tillverkningsföretag

Companies constantly strive for the perfect order which enables them to satisfy and retain their customers. This is a difficult process that can be facilitated by using different picking technologies. In this study, a research of the picking technologies Pick-to-Light and Pick-to-Voice have been made to investigate when each technology is suited.In order to collect relevant information and data to be able to answer the question formulation, a qualitative study with interviews have been made. The purpose of this essay was to investigate Pick-to-Light and Pick-to-Voice to see when each technology is best suited and to see what the differences between the technologies are. With our essay we wanted to help manufacturing companies to make the right decisions when implementing a picking technology.The results showed that those picking technologies give companies a higher picking quality and an increased work efficiency since the order picking is faster to perform, and that picking errors are reduced.

Social behaviour and time budget of breeding bulls

The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.

Utvärdering av miljöbonus IP-lantbruk :

The Dairy business is changing a lot because of some scandals in the agricultural area for example the BSE crises in Great Britain. Because of the scandals the food industry and the farm association have created a certifying system; IP-Sigill Swedish standard system. We contacted Skånemejerier as they have been successful in the certifying area. They asked us if we wanted to do a study in the certifying area of dairy farmers. At Skånemejerier they gave us most of the literature in the area about certifying. The result of the study, is that we have taken up the most common remark?s. The most frequent remark is journal over routines in management of dairy cows on daily basis. Another remark of the study is that the frequency of the remarks decreases with greater production..

Underlag för bedömning av energibrunnar inom vattenskyddsområde

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Kännedom om och inställning till SAPERE-metoden : En undersökning bland personal på förskolor, låg- och mellanstadieskolor

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

Visualisera personuppgifter i ett tidslinjegränssnitt : Utvärdering av ett mobilt användargränssnitt till Data Track i A4Cloud-projektet

Syftet med denna C-uppsats var att implementera ett visualiseringskoncept för att presentera data i ett tidslinjegränssnitt med hjälp av Font Awesome-ikoner inom A4Cloud-projektet. Den huvudsakliga målgruppen utgör personer som främst arbetar inom A4Cloud-projektet.För att kunna belysa brister i visualiseringskonceptet genomfördes användartester där testpersonerna fick använda sig av det upprättade tidslinjegränssnittet samt en konstruerad plattform för att besvara ikoners betydelse. Både kvalitativa intervjuer samt statistiska framställningar genomfördes under studien.De slutsatser som kan dras från denna studie är att några element var svåruppfattade som interaktiva element och svåra att åtskilja från resten av gränssnittet. Testpersoner, blev under studien, tillfrågade under intervjun om de kunde tänka sig använda tidslinjegränssnittet i sin vardag. Orosfaktorn verkar inte ha spelat någon roll när testpersonerna besvarade tidigare nämnda intervjufråga, utan behovet att vilja ha koll på sina delningar med diverse tjänster verkar vara det som avgör..

Kvinnliga elitidrottares karriäravslut : - en kvalitativ studie om rollutträdesprocessen

This study used a qualitative interview design to explore the experiences of seven Swedish female elite athletes and their career retirement. The athletes were engaged in three different sports; track and field (athletics), handball and golf and five of them are former professional or semi-professional athletes. The process of their athletic role exit was based on the theoretical findings of Ebaugh (1988) and her four phases: First Doubts, Seeking Alternatives, The Turning Point and Creating the Ex-Role. The findings reveal that for these female former elite athletes Seeking Alternatives already starts before the First Doubts and that possibly the athletes at an early stage have insights of the discontinuity of their athletic career. The importance of transferring their role residual to future paths in life was stressed among the female athletes in order to be able to have a smooth transition process.

Betesdrift vid automatisk mjölkning i ekologisk produktion :

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.
