FPGA-design av en STDM-baserad multiplexer för seriell multiprotokollskommunikation

The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.

En proteomisk utvärdering av olika metoder för att samla uterussekret hos sto :

This study was performed in order to evaluate if the method of collecting uterine secretion by the tampon-method is representative for use in studies of uterine secretions in mares. Uterine secretion collected by tampon in six mares was compared with secretion collected by aspiration, regarded to be a native sample, at the Institution of Obstetrics and Gynaecology, SLU, Uppsala. Proteinanalysis was made at the Department of Farmaceutic Bioscience, toxicological unit, Uppsala University. Cytological smears and ultrasonography was used to assess if the tampon had caused an inflammatoric reaction that could influence the protein content of the samples. The results suggest that the tampon and aspirat method do not differ when it comes to proteinconcentration, but the distribution of proteins differ between these different collection methods. This difference could not likely be explained by means of proteins due to an inflammatory reaction from the tampon, since neither the cytological nor the ultrasonographical examination gave any indications of inflammation.

Hur ser vi på vår framtid? : En kvalitativ intervjustudie om idrottslärarstudenters attityder och syn på ämnet Idrott och hälsa och yrket som lärare i Idrott och hälsa

AimThe aim of the study is to examine how future teachers of Physical Education view the subject, the occupation and their attitudes about the future and create an understanding about this through these research questions:In what way do the teacher students justify the subject Physical Education?How do teacher students view the future of the subject and the occupation?According to the teacher students, what and whom affect the subject?

Eight teacher students of Physical Education were interviewed. The interviews were between 27-57 minutes. They were recorded, transcribed and then analyzed from a socio-cultural perspective as well as Bernstein?s theory of classification.ResultThe participants justify the subject in words such as that it gives the students? knowledge about how to uphold a decent standard of living and an understanding for the correlation between physical activity, nutrition, health and wellbeing.

Omsorgskvalitet i äldreomsorgen : Ett begrepp i utveckling

This study is based on interviews with heads of unit, care staff and senior representatives from a total of six people. We have in this study directed our focus on care quality in the elderly as a concept in development. It appears, when the elderly do not have any dependents, it is even more important that staff supports some extra where no relatives are involved.Quality of life is the broader concept of good quality care and where a good quality of care is a necessary condition for a good quality of life. According to the social services care is the target that older people will live a good life and be allowed to live in a safe environment, which we intend to investigate in this study. Opportunity for greater influence should now be given to older people and their families on how interventions should be designed and implemented.

Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp

Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.

Att vara närstående på en intensivvårdsavdelning : upplevelser av delaktighet och patientens omvårdnad

Syftet med studien var att beskriva hur närstående till intensivvårdspatienter upplevde en intensivvårdsavdelning (IVA) med fokus på delaktighet och omvårdnad. I studien intervjuades fem närstående. Intervjuerna analyserades med hjälp av en förenklad variant av meningskodning och tre kategorier som beskrev de närståendes upplevelser av IVA utvecklades. Kategorierna benämndes: "Första intrycket av IVA", Att leva med osäkerhet" och "Att vara delaktig". De närstående upplevde ett inre kaos när deras anhörig vårdades på IVA och använde sig av olika copingstrategier.

Kompaktaggregat till Passivhus i Sverige

Kompaktaggregat är ett integrerat FTX- och FVP-system som används i passivhus. Vi har gjortenergiberäkningar i programmet VIP+ för att se hur kompaktaggregatet skulle kunna fungera ipassivhus i Sverige.De resultat vi har fått fram ur VIP+ visar att passivhus med ett installerat kompaktaggregat klararav att nå passivhuskraven ända upp till Skellefteå. De beräknade värdena understiger kraven förpassivhus, men en viss marginal behövs för att kraven ska nås även efter uppförandet avbyggnaden. Vi har även tolkat tekniska uppgifter på ett sätt som enligt oss har en positiv effektför passivhus på kallare orter. Därför tror vi inte att värdena för de tre nordligaste platserna ärhelt tillförlitliga.

Programmerbar signalanpassning

The data acquisition system COMET developed by Saab AB contains a unit for signal conditioning and A/D conversion, called KSM. The varieties in signal conditioning constitutes of a number of specific PBAs and maintenance as well as reconfiguration of these are complicated not to mention costly. This thesis has aimed to investigating whether the signal conditioning circuits can be replaced by a general purpose, programmable solution. If so, how can this be done? The development has been carried out by evaluating ideas through the use of a laboratory environment and has resulted in an analog design for laboratory purpose.

Patienters upplevelser av patientdagbok från intensivvårdsavdelning

Aims: The aim of this study was to describe how patients that received a patient diary after their stay at an intensive care unit (ICU) had used the diary and if they found it useful for dealing with their stay in the ICU. The study also aimed to investigate if the patients felt a need for discussing their stay in the ICU and the diary with a registered nurse.Method: The study was performed as an interview study with explorative design. Six informants participated in the study. Recorded personal interviews were held with the informants. The recorded material was transcribed and analysed using qualitative content analysis on a manifest level.Results: This study shows that informants have used their diaries to establish a conception of what they have experienced during their stay in the ICU.

En mångkulturell skola : En studie om främjandet av elevers kulturella kunskaper på en mångkulturell skola

My thesis is based on a qualitative study. The purpose of the study is to investigate whether the educationalist at an especially chosen school in Stockholm promotes the students multicultural background in the education or not.This is due to the fact that the Swedish school to a considerable degree reflects the multicultural Swedish society. The socio-cultural starting point is when people come together and meet. The language is the tool of the socio-culture and it is the dialogue, discussion and sympathetic understanding that makes people meet.The cultural concept is diffuse and very wide. Everyone has their own definition of it.

Paradoxens styrka och kraft : En studie av paradoxala inslag i Samuel Backetts verk i väntan på Godot

AbstractThe purpose of this investigation is to find out how the pupils can discover and to feel joy in their creative art activity and also to believe in their own ability. The aim is to figure out if creative art activity is able to raise the pupil?s self-image. By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.

Formulera-Kommunicera-Utvärdera

The Swedish governments goal for the public health is to operate for a society with good conditions to be healthy. Many people today are very conscious about their health, at the same time alcohol is a recurring element in many day-to-day situations. IOGT-NTO is an organization that is working towards making sobriety to be the rule rather than the exception. This work is linked together by the organizations communication, which is a vital part to be able to present a unified view outward. In order to do that, it is particularly important that there are common goals and strategies to work towards.

Validering av glidande statorfötter på Hissmofors G6 och G7

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.

Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.
