Full textAnimal migration is a well known natural phenomenon and bird migration is perhaps the most obvious type. In some bird populations all individuals migrate, while in others only a fraction of the population migrates. The blue tit is a partial migrant; i.e. some individuals in the population migrate while others are sedentary. Some years, large numbers of partial migrants leave their breeding grounds and appear as invasion species in other areas. Shortage of food and high population densities are suggested as two important releasing factors. Theory predicts that juvenile birds, especially females, should arrive earlier since they are smaller and therefore are forced to leave their birth areas first.
In this study, the migration of blue tits at Hammarö Bird Observatory in northern lake Vänern (HBO) was examined with respect to age and sex distribution. During the autumns of 1977-2005, a total number of 13 944 blue tits were caught and ringed at HBO. A large fraction of the caught blue tits were juveniles, of which female and non-sexed birds dominated. Juvenile males were the third largest group, whereas adults were only caught in small numbers. The period when most birds arrived was between 28th of September and 2nd of October, but juvenile females did not arrived significantly earlier. The median arrival date was the 2nd of October, and the mean arrival date was 30th of September. There was a trend of earlier arrival dates, which may be due to warmer spring climate leading to an earlier breeding start. Analyses showed that the proportion of juveniles increased significantly with mean arrival date and total number of birds caught. Comparison between HBO, Falsterbo and Ottenby showed that birds arrived significantly earlier at HBO. In 1990 and 2003 all bird observatories (HBO, Falsterbo, Ottenby and Jomfruland) captured more birds than respectively stations average and in 1995, 1998 and 2002 fewer birds than average were captured at all sites.
Förekomsten av migration är vida känt i djurvärlden och fåglars flyttning är kanske den mest uppenbara typen. I vissa populationer flyttar alla fåglar, i andra flyttar ingen. Blåmesen tillämpar partiell migration, dvs. en del individer i populationen flyttar medan andra stannar. Vissa år lämnar partiellt flyttande fåglar fortplantningsområdet i stora antal och invaderar andra områden – dålig födotillgång och höga populationstätheter är två viktiga, utlösande faktorer.
I den här studien undersöktes successionen av flyttande blåmesar vid Hammarö fågelstation i norra delen av Vänern (HBO) med avseende på ålders- och könsfördelning. Under höstarna 1977-2005 fångades och ringmärktes totalt 13 944 blåmesar vid HBO. Den största delen av de fångade blåmesarna var ungfåglar, av vilka honor och obestämda fåglar dominerade. Juvenila hanar utgjorde den tredje största gruppen, medan de adulta fåglarna var få. Den period då de flesta fåglarna fångades var 28 september till 2 oktober. Mediandatum för fångst var 2 oktober, medan medeldatumet var 30 september. Tvärtemot förutsägelserna anlände inte juvenila honor signifikant tidigare än andra kategorier. Det finns en trend att fåglarna fångas allt tidigare på hösten, vilket kan vara ett resultat av ett varmare vårklimat med tidigarelagd häckning som följd. Regressioner visade att proportionen juvenila fåglar ökade signifikant med medelankomstdatum och med det totala antalet fångade fåglar. En jämförelse mellan HBO, Falsterbo och Ottenby visade att fåglarna anlände signifikant tidigare till HBO. 1990 och 2003 var de enda år då HBO, Falsterbo, Ottenby och Jomfruland fångade fler fåglar än respektive stations medelvärde. Åren 1995, 1998 och 2002 fångades färre fåglar än medelvärdet på samtliga stationer.

Full textThe reason to write about cellulose lacquer is that from year to year there are more and more furniture withsuch transparent coatings that come to the conservation and restoration workshops. The furniture comesmainly from the 1950´s and 1960´s (when it was one of the most common type of transparent finishes) butalso from the 1920´s and 1930´s. Today the furniture from the 20th century has become antiques and soughtafter on the market. Therefore, they are still valuable with their original coatings that would need to be protectedand preserved.This type of transparent finishes causes many problems for the conservator, but I have concentratedon how to partially improve the lacunae that you can interpret here as a break in continuity, gaps in transparentcoatings (the word comes from Latin – lacuna, lacunae).Earlier, the most common method of restoring a furniture with damaged transparent coatings was toremove the old and add a whole new one. In modern times, it is obvious that it is not very environmentallyfriendly and healthy to clean up and add new nitrate cellulose laquer, with conservation attitude is better torepair old finishes that are original. One should learn how to handle such transparent coatings problems.Therefore, there is a need to find methods and materials that help fill gaps effectively. I have also evaluatedthem based on preserving and restoration ground rules.Through practical experiments, based on written sources as well as on my and my supervisors experiencein this area, I have presented and evaluated some methods of filling lacunae in my bachelor thesis.

Full textThe effects of global warming has lead to a temperature rise in the atmosphere. Many countries have agreed to reduce the greenhouse gas emissions in order to mitigate climate change. The energy production today is highly dependent on fossil fuels and thus one solution to reduce emissions is to use more renewable resources. Solar cells are today growing on the market and in Sweden one can expect that solar energy will represent 5 – 10 % of the electricity production in year 2040. Partial shading is still a problem causing losses in the electricity production for solar cells. To reduce the losses due to shading bypass-diodes are built-in on modules. Further successful method can also be to change the interconnections among moduls in a system. At the time of writing this paper, configurations with series-parallel connections between modules are most commonly used, but during partial shading it has been shown that increasing interconnections can increase the outgoing effect. The purpose of this study was to show guidelines for the investor of solar cells, who plans an installation near objects that will creates shadows on the cells. The target consisted of two parts. First, there was an experimental objective which compared two different system configurations where the solar modules first were connected in series and thereafter in “Total Cross Tied”. The other part of the study considered a theoretical simulation to answer questions as how the energy production during a year was changed for a solar panel by placing it near a chimney. Thereafter it should also state guidelines on how to place the panel around the chimney so that the shading effects are no noticeables. The experiments were done outdoors and the system consisted of sixteen monocrystalline solar panels. First the panels were connected in series (S) and thereafter in “Total Cross Tied” (TCT). The system included also an inverter that changed direct current from the solar panels to alternating current. In the first experiment the electricity produced from the systems was measured, whereof one module was exposed to different types of shading. As a final experiment, one module was separated from the system where is was exposed to the same shading pattern as before. The results showed that the PV systems had an efficiency of 16 % for an irradiance between 400 – 700 W/m2. For lower irradiances than 400 W/m2 and higher than 700 /m2 the systems experienced a decreasing efficiency of about 1 – 2 %. A high irradiance occurs normally during the middle of the day when the solar cells have a higher temperature, which decreases the efficiency. The experiments proved that shading more cells so that current will flow through more bypass diodes resulted in a lower electricity production. For example if only one bypass diode is activated it means that the remaining cells that are not connected to that bypass diode can work freely and gets a higher maximum power point (MPP) on the IU characteristics. When a module got completely shaded it reduced the electricity output power with 7,72 % for the system with series connected modules. For the TCT-configuration the system experienced a reduction of 13,87 %. These results may be a contradiction according to previously research. A conceivable explanation is that the TCT-configuration produces higher current, which can exceed the allowed value for a functionally bypass diode. If the current in a shaded module flows through its bypass diodes it results in a short-circuit of the module so that it cannot contribute to the voltage. The more parallel PV arrays a system includes, a higher effect loss will occur since the unshaded strings may experience an identical voltage drop as the shaded one. The TCT-configuration included two strings connected in parallel. The sensitivity analysis where one module was separated from the whole system showed nearly the same results as for the whole system. Placing the shading object far away from the module resulted in a higher electricity production for some tests, as it is only the direct radiation that disappears. The simulations results were expressed in terms of “shading performance” and it showed how much a shaded solar module produced compared to an unshaded. It was shown that the parameters that had the biggest influence on the results were the height of the chimney and how far the solar module was placed with respect to the chimney. As a worst-case scenario, the shading performance was 41 % for a series-connected module. This was for a chimney with 2 m of height that placed next to the solar module. The results indicated that having a higher chimney had a decreasing effect of the shading performance for the solar module. To get a higher shading performance one can choose to place the solar cells at a larger distance from the chimney. Conclusively, placing the solar module so that the chimney is located to the south of the module the shadow will affect the panel more, and a longer distance is therefore needed. If the solar cells are located on a distance that is at least 0,3 m from a shading object with a height of 0,5 m, it means that the solar cells will produce 95 % of what that would have given unshaded. For a shading object with a height of 2 m it means that the solar cells must be placed at a distance of 2,1 m from the object.

Full textDetailed information about the wind conditions on a site is a necessity for calculations of profitability from a wind power project. Hence the continuity and the correctitude of the measurements are crucial when making the site evaluations. Due to the season dependence of the wind conditions the measurements also needs to be done for at least a whole year. During wintertime and particularly on higher altitudes and/or latitudes the instruments may be affected by icing. An iced up anemometer often underestimates the wind speed and severe icing can lead to instrument breakage and loss of data. Identification of inaccurate measurements is of great importance in the analysis of the site’s energy potential. The difficulty in detecting light to moderate icing lies in that the wind speed and the standard deviation of the wind may seem normal, although the anemometer is underestimating the wind speed due to icing. In this thesis 1 Hz data from cup anemometers are analysed in search for a mathematical way to determine whether the instrument has been affected by icing during the measurement. An experiment has been performed simulating different types of icing on anemometers. The wind velocity distribution of an “iced up” anemometer has been compared to the wind velocity distribution of an unaffected anemometer for the same measuring period. Also the turbulence intensity and the change of mean wind velocity between observations have been evaluated. The comparison of these statistical variables between the instruments has showed that none of them are applicable for detection of icing. In addition to analysing data from the experiment a pre-study on the subject has been made analysing measurements with possible icing from the Suorva valley. Also, the results from the experiment have been compared to results from a conventional measuring mast placed in the northern part of Sweden. For the analysis of the mast data an algorithm for detection of icing during measurements has been implemented. This automatic detection of icing is based on assumptions about the standard deviation of wind speed, the standard deviation of the wind direction, the change of wind direction and regression between wind velocities of two heights.

Full textBakgrund: Befintlig alignmentteori berör inte de svårigheter som företag möter i att uppnå strategisk alignment, särskilt när de genomgår större förändringar. De förändringar som amerikanska och europeiska fullserviceflygbolag har genomgått genom att introducera lågprisalternativ visar att det har varit svårt att skapa lönsamhet.
Syfte: Syftet med uppsatsen är, att med hjälp av exempel från flygbranschen, konkretisera befintlig alignmentteori, sätta alignment i relation till olika förändringsprocesser, samt att utifrån de olika förändringsprocesserna diskutera förutsättningar för att uppnå alignment vid en partiell förändring.
Genomförande: Sekundärdatastudie av den amerikanska och europeiska flygmarknaden.
Resultat: Förutsättningarna för att uppnå alignment vid partiell förändring kan underlättas av en dialektisk förändringsprocess i kombination med ett livscykelsynsätt, och försvåras av en teleologisk eller evolutionär förändringsprocess.

Full textThe study is conducted for Freezing Food Småland Öland AB. The purpose of the study was to propose measures to decrease the facility’s energy demand and to calculate the payback time for these suggestions. By means of using simulation software along with data from practical measurements different configurations in the facility were tested. The study resulted in suggestions consisting of an increase of the temperature in the freezing room and the temperature in LTB1.Those suggestions increases the facilities COP and decreases the energy consumption. Proposals to curb the ice growth are the insulation of components such as pipes and valves. Insulation results in a small decrease in energy demand but greatly increases the accessibility and also decreases the risk of corrosion. Through load tests conducted on the compressors it showed that the compressors were not driven in the optimal load range, suggestions were made for operation in a more favourable load range. Thus increasing the efficiency and cutting the maintenance costs. From the results it is shown that the facility is well built and dimensioned against thermal transmission. Though it turned out that the floor heating accounts for a disproportionate amount of the thermal transmission.

Full textBackground: The health benefits of breastfeeding are well known and since 1992, Swedish hospitals aim to provide care according to international guidelines of breastfeeding support. Despite this, there are inadequacies in the care provided, and the frequency of breastfeeding in Sweden is statistically decreasing. Aim: The aim of this study was to investigate the duration of breastfeeding among primiparas, if the duration was associated with the provided care and with how the mothers valued the help and support they received at the initiation of breastfeeding. Method: A quantitative longitudinal with consecutive sample was conducted. At discharge from hospital, 63 mothers were asked if they wanted to participate in a survey about breastfeeding and the related care, and 52 mothers filled in the questionnaire. After nine to twelve months the participants were contacted by phone for a short follow-up, and 50 mothers chose to participate. Results: The median duration of exclusive breastfeeding was three months and three weeks and the median duration of partial breastfeeding was eight months. The evaluation of the breastfeeding support was higher at the first data collection but did not appear to correlate with the duration of breastfeeding. Of the investigated factors; skin-to-skin contact immediately after birth, breastfeeding within two hours after birth and hands-on support, none of them led to differences in breastfeeding duration. Breastfeeding duration was adversely affected if the infant was given formula at the maternity ward and if the infant was born by Caesarean section. Feeding by infant formula led to a shorter duration of exclusive breastfeeding and birth by Caesarean section led to a shorter duration of both exclusive and partial breastfeeding. Conclusion: The median duration of exclusive breastfeeding was three months and three weeks and the median duration of partial breastfeeding was eight months. The infant being given formula at the maternity ward, and being born by Caesarean section were factors that adversely affected the duration of breastfeeding. However, there was no association between breastfeeding duration and; perceived breastfeeding support, skin-to-skin-care, breastfeeding within two hours or hands-on support.

Full textThis bachelor’s thesis is made on behalf of Byggteknik AB. The problemthat is studied in this paper concerns the techniques of reinforcing asteel column that is already built into a wall. The reason for why thiswould become necessary is for example if a column of an insufficientdimension has inadvertently been built in to the wall. Thereinforcement of the steel column will be conducted by weldingadditional plates of varying sizes along portions of the column in orderto increase the column’s stability and bearing capacity.The work is based on literature studies in order to investigate differentmethods to calculate the stability and bearing capacity of a column, aswell as calculations based upon the chosen methods.The results of this work show the relative difference between variousways of reinforcement of the column and the influence of differentloads bearing on the column.The study concludes that, in case only a limited reinforcement of thecolumn is required, the performed reinforcement need not cover theentire length of the column. This limits the resources that have to bedevoted to the reinforcement and thus reduces costs, both relating tolabor and to material.However, in case a major improvement of the column’s bearingcapacity is required, a reinforcement that covers the entire length of thecolumn increases efficiency as it improves the column’s bearingcapacity per cubic millimeter.

Full textIn an era of significant environmental threats, increasing carbondioxide emissions and rising electricity demand, it is important that the development of cheap and efficient renewable energy continues around the world to compete against cheaper, non-renewable, energy sources. To do this, the development of solar power have to continute so that countries and companies choose to invest solar power insteed of non-renewable energy. More specifically, it can be done through the development of new, more efficient, solar cells modules. In this study, a new sort of solar cell module, SmartPlus - developed by Innotech Solar, is compared to their standard module EcoPlus to investigate whether the new module may contribute to the higher proportion of solar-generated electricity in Sweden and there by reducing carbondioxide emissions. The new photovoltaic module is designed to take better advantage of the solar radiation when a portion of the module is exposed to shade, therefore will this study simulating the two modules in a solar panel plant where there is internal shading between the rows. Shading of photovoltaic modules currently leads to substantial losses in electricity generation because of the modules design and the purpose of the study is to investigate whether the new photovoltaic module are more efficient than the standard solar module that currently is in use. The aim of the study is to create and verify a simulation model and simulate a solar park in Sweden where the results variation depends on the spacing between the rows in the solar panel plant and if the modules are vertically or horizontally positioned to provide a variety of shading. The solar park that provides maximum power generation is a solar park with SmartPlus modules with horizontal position, but since the availability of land is often a limiting factor the vertical position should always be preferred. The result shows that when choosing module to a solar the choice between SmartPlus and EcoPlus is not the most important factor. Even though SmartPlus consistently has a higher electricity production on an annual basis, the difference is marginal to EcoPlus, however, factors such as row spacing and module placement have a far greater impact on electricity generation and efficiency of the solar panel plant.

Full textDe för närvarande tillgängliga simuleringsverktygen för solcellssystem erbjuder inte en tillförlitlig metod för simulering av delvis skuggade system eller system med moduler med olika elektriska egenskaper. De metoder som är tillgängliga för att simulera detta tillförlitligt kräver datorkraft som inte är allmäntillgänglig. För att göra det möjligt att simulera dessa typer av system föreslås en metod baserad kring programvaran "System Advisory Model" (SAM). Metoden utgår från antagandet att skuggning är binärt, vilket innebär att en modul kan antingen vara helt skuggad eller inte skuggad alls. Två olika globala IV-modeller presenteras och utvärderas i jämförelse med en detaljerad Matlab global IV-modell baserad på enkel-diods ekvivalenta kretsen. Denna metod bortser dock från effekterna av bypass-dioderna i PV-modulen och detta antas medföra betydande fel som måste kvantifieras, detta bör då göras med hjälp av två-diods ekvivalenta kretsen. Slutligen så kan metoden inte anses pålitlig förrän den har blivit verifierad med verkliga data.

Full textFPGA-baserade system har tidigare främst använts för snabb och kostnadseffektiv konstruktion av prototyper vid framtagandet av applikationsspecika integrerade kretsar (ASIC). På senare år har användandet av FPGA:er i inbyggda system för implementation av hårdvaruacceleratorers såväl som huvudsaklig beräkningsenhet ökat. Denna ökning har möjliggjorts mycket tack vare den utveckling som har skett av rekonfigurerbara integrerade kretsar: från de mer traditionella Complex Programmable Logic Devices (CPLD) till helt CMOS-baserade FPGA:er. Nu inleds en ny era för FPGA-baserade system tack vare möjligheten att under körning rekonfigurera delar av FPGA:n genom så kallad partial run-time reconguration(RTR) - en teknik som redan idag finns tillgänglig i produkter på marknaden. Tidigare forskning visar att användandet av en RTR-baserad hårdvaruarkitektur kan ha en positiv effekt med avseende på prestanda såväl som strömförbrukning. Att använda RTR-baserad hårdvara innebär dock flera utmaningar: En ej försumbar rekonfigurationstid måste tas i beaktning, så även den icke-deterministiska exekveringstiden som en rekonfiguration kan innebära. Vidare måste anpassningar av mjukvaran göras för att fungera med en hårdvaruplattform som förändras över tid. Denna uppsats syftar till att undersöka prestandan hos ett modernt RTRbaserat SoC (Xilinx Zynq 7020) med fokus på rekonfigurationstider och dess förutsägbarhet, prestanda ökning, begränsningar samt nödvändiga kompromisser som denna arkitektur innebär. Huruvida en applikation kan dra nytta av en RTR-baserad arkitektur eller inte kan vara svårt att avgöra. Den insamlade datan som presenteras i denna rapport kan dock fungera som stöd för hårdvarukonstruktörer som önskar använda en RTR-baserad plattform.
