Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

En argumentation om berättelser - En studie om effektivitet och reklamkapital för repetitionsstrategier

Despite narrative advertising being an increasingly popular strategy among brands today, little research has examined the different expressions of repetition variation strategy in comparison to its alternative, argumentative advertising. Still unexplained is whether the appreciation and recognition created from successful storytelling-based commercial campaigns is a result of execution or the format itself. This study aims to investigate four repetition variation strategies, three narratives and one argumentative, to determine which one is the most effective and also which one that generates the highest advertising equity. An experiment was conducted through exposing four groups of Swedish High School students to text-based advertising manuscripts customized after format, where each group was exposed to ads on two separate occasions. The result showed evidence of narrative advertising being easier to comprehend, which according to theory should lead to higher advertising effectiveness.

Koppar på drift

In my project, Cups on the run, I have studied the relationship between ceramic utility objects and different environments, when moving them off the table. My background as a potter has been the starting point. From there, I wanted to see if I could expand my craft to the space beyond. With the cup, which for most people has a clear function and a relation to us human, in repetitive structure I explored the spatiality and architecture in various environments. Life fascinates me through how everything is made up of tiny parts that together create the tangible and intangible.

Distriktssköterskors erfarenheter av att använda MI- modellen och behovet av repetition och fortbildning

Att arbeta sjukdomsförebyggande genom livsstilsförändringar är en viktig del av distriktssköterskans ansvarsområde. MI-modellen används som ett verktyg för att motivera patienten till livsstilsförändring vid ohälsosam livsstil. Sextio procent av distriktssköterskor innehar den grundläggande kompetensen om MI-modellen men endast 26 % av dem får möjligheten till regelbunden träning och repetition av modellen.Syftet med studien var att belysa distriktssköterskors erfarenheter av att arbeta enligt MI- modellen vid livsstilsförändringar, samt deras erfarenheter av fortbildning och repetition av modellen.En kvalitativ metod användes och åtta semistrukturerade telefonintervjuer utfördes med distriktssköterskor i södra Sverige. Vid dataanalysen användes manifest kvalitativ innehållsanalys.Analysen av data resulterade i fem kategorier: Användbar vid livsstilsförändringar, Skapar Empowerment, En svår balansgång för att inte ta över, Bygger på samarbete och motivation, Utveckla och aktualisera sin kunskap. Distriktssköterskorna beskrev modellen som användbar och resultatrik vid livsstilsförändringar.

Går det att mäta blodtryck med fotopletysmografi och bioakustisk sensor i kombination?

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

Skräckfilm och bilden inom bilden : En analys av rörlig bild inom filmen och dess reflexivitet i de japanska skräckfilmerna The Ring, Pulse och Dark Water

Syftet med denna uppsats är att skänka en grundläggande illustration av hur relationen bildinom bild och skräck kan se ut. Studien koncentrerar sig på estetiken och reflexiviteten hosbilderna inom bilden hos de japanska skräckfilmerna The Ring, Pulse och Dark Water. Dessabilder består av ett videoband i The Ring, webbkamerabilder i Pulse och övervakningsbilder iDark Water.Användningen av rörliga bilder inom rörliga bilder är reflexivt i den meningen att vimedvetandegörs om filmmediet självt som en konstruktion av bilder. Detta fenomenuppmärksammar oss också på akten att se. Syftet i skräckfilm är att skapa känslor av olust ochskräck hos oss och detta åstadkoms, bland annat, genom hur bilderna ser ut och är upplagda.Ett återkommande element hos bilderna inom bilden hos våra filmer är otydligheten hosflera av dem och detta att vi inte kan se bilden tydligt kan ge upphov till olustkänslor.

Multiplikationstabellen : En jämförelse mellan strategi- och repetitionsbaserad undervisning

Studien avgränsas till elever i årskurs 1 till 6. Materialet samlades in genom en iterativ sökning på åtta databaser för vetenskapliga publikationer. Det insamlade materialet bestod av sjutton vetenskapliga publikationer.

Utprövning och prosodisk analys av ord- och nonordsrepetition på en grupp barn med typisk utveckling

Previous research has confirmed that the ability to repeat non-words has a close connection to a child?s language acquisition (Adams & Gathercole, 2000; Gray, 2003; Sahlén, Reuterskiöld-Wagner, Nettelbladt & Radeborg, 1999). It is also known that a repetition task is aided if the word is well known to the child (Roy & Chiat, 2004; Sahlén, m.fl., 1999). A relatively under-investigated area is that of the influence of prosodic variables on repetition of words and non-words.In the current study, 44 Swedish children between the ages of four and six years with typical language development were tested regarding word- and non-word repetition abilities. The words and non-words were matched based on stress, tonal word accent and number of syllables.

Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Frekvensreglering i det nordiska kraftsystemet

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Efficient Frequency Grouping Algorithms for iDEN

This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

Effekten av frekvenskomprimerande hörapparater på taluppfattningen hos patienter med grava diskantnedsättningar ? En experimentell studie

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Narrativ förmåga vid afasi : analys av strategier vid gemensamt berättande

Aphasia is a linguistic impairment which affects communication and may have an impact on a person?s narrative ability. The purpose of the present study was to analyse the narrative ability in aphasia by narrative interviews with people with aphasia and their partners. The interviews were scrutinised for strategies used in joint narration involving couples where one of the spouses has aphasia. The definition of strategies was methods to cope with communicative difficulties often due to aphasia.
