This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
Plan för multifunktionella buffertzoner längs Vramsån påMalörten AB : s jordbruksfastigheter
To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

Känslan i bilden : Sociala taggars användbarhet vid bildsökning i Flickr
Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.
Processutveckling av borstgradning
During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.
Stärkelsers funktion som konsistensgivare vid olika temperaturer i pulversoppa : en experimentell kvantitativ studie
More often consumers demand instant dry soup that can be prepared with a water temperature below 100o C, which is currently not possible, because the dry soup becomes too thin when using water with a lower temperature. In this study, various kinds of starch studies were made to optimize the starch used in the existing product to make it more viscous at both high and low temperatures. The result was that one of the two starches present in the existing product was retained by change in quantity as it contributed to important flavor parameters. The second was removed and replaced with a starch that made the product more viscous at lower temperatures. To find out if the new product differed from the existing product a viscosity measurement and a sensory paired preference test were made.
Bilden av bilden bildbeskrivning i ABM-samarbetet PictureAustralia, en fallstudie.
This thesis aims at exploring a national collaborative gateway-service, PictureAustralia, hosted at the National Library of Australia. This will be done by means of investigating some underlying principles for descriptive standards and conventions as of the library discourse which is the objective of bibliographic control and access. The reason to do this is to bring some main features of these principles into the context of a cross-institutional cooperation between libraries, galleries/museums and archives in a picture database service. The attention will lay on the objectives of what functions the system is designed to perform to give access, as defined by Elaine Svenonius in the Intellectual Foundations of Information Organization 2000, and how these objectives will affect this particular database-service collocating performance, which is a system- and logical approach. Though, this study will be done in an explorative and qualitative way, by a case-study, which is to examine some sample metadata records emanated from different institutions in this project.
Att dela eller inte dela? : Vad som möjliggör respektive förhindrar produktdelningssystem
Product sharing systems is recently starting to become a more common phenomenon. Carpools exist in more than 40 Swedish towns and both Stockholm and Gothenburg have established bicycle sharing systems. Other products for which sharing systems have been established throughout Sweden are clothing and tools. From the point of view of the consumer, product sharing systems is a form of consumption which can be placed somewhere in between renting and privately owning a product, where the consumers usually pay a membership fee or a monthly fee to have access to the products whenever they need them. The concept is relatively new, and there are many products for which product sharing systems do not exist.
Site preparation, planting position and planting stock effects on long-term survival, growth and stem form properties of Pinus contorta on southern Iceland
In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.
Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro
The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.
Det kanske är lite meningen att man ska vidga sina vyer. En undersökning om yrkesförares inställning till läsning och användning av vägkrogsbibliotek.
This Masters thesis is a study of the truck-driver profession and their use of libraries located in gas-stations and restaurants along the highways in Sweden. The reason for this interest is the positive trend that has occurred concerning men without any university education and their reading-habits, that is due to their increased interest in listening to audio books. This challenges the general opinion that this group is not particularly interested in reading literature. Questions posed in this study are: How do the truck-drivers relate to the activity of reading literature, what part does the road-libraries play, and how can the services that the road-libraries offer be improved according to the truck-drivers. The method used in the study is interviews made by telephone.
Att växa i lekmiljöer : hållbar och funktionell växtanvändning i lekmiljöer för förskolebarn
The preschool constitutes a big part of many
children's everyday existence. Its contents are
therefore of great importance and the environment
deserves a well thoughtout design. In this
study, surveys in field and literature have resulted
in conclusions around how plants can be used in
children's play environments, in order to contribute
to the experiencerelated values. The aim
is to present conclusions to lean on when drawing
up designproposals for new playgrounds,
especially where the natural conditions are not so
favorable. The first question that is responded to
is how plants can be used in order to enrich the
children's play environments.
Fl?ckreducering ? Bl? Vinranka En j?mf?rande studie av tv? efterbehandlingsmetoder vid reng?ring av glaserad keramik
This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.
Klinikintern statistik : en fallstudie kring behov av och möjligheter till framtagandet av ett statistikverktyg
The health care sector is one of the most information-intensive institutions in Sweden. Big investments in information technology have been made to ensure efficiency and quality within organisations in health care. This has led to high requirements in documentation and resulted in an increase in administration which gradually more often is done by nurses and doctors. A major problem is that it is difficult to gain access to the information recorded in all the different systems, which is their objective. This causes double documentation instead of being a support in follow-up performance.
Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
