AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.

In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.

The purpose of this paper is to investigate the possibility of replacing data from highspeed filming (Qualisys motion capture) with data from Inertial Measurement Units (X-io technologies), when used to run a model of torso and pelvis in OpenSim. Qualisys motion capture data is used as the golden standard to validate the result visually and with Bland-Altman plots.In order to obtain comparable data experiments are conducted where both methods of collecting data are used simultaneously. Data from the IMU's then need to be processed in Matlab before it can be used to run the OpenSim modell. Several Matlab programs rotate the IMU data to a static reference frame, filter and integrate it, then create viritual markers that correspond to Qualisys' optical markers.The conclusion is that using IMU as a method for collecting data can replace Qualisys in some applications, but not in ones that require high precision. However, this paper only begins the examination of IMU's and there are most likely improvements to be made..

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Since several lifestyle diseases are associated with obesity much research is carried out within the area. Researchers have found that oxidation of fatty acids within the body?s cells may give rise to peripheral signals which regulate food intake, but it is still unclear where such a mechanism takes place. Although much evidence suggests that it is the hepatocytes in the liver that send signals regulating food intake, some researchers have begun to question this theory. Instead they argue that the mechanism takes place within the enterocytes since they are well localised in the gut for such assignment.

I sjukvården världen över tas dagligen tusentals röntgenbilder. Användningsområdena är många, men i de flesta fall är syftet att i något avseende avgöra patientens hälsa. Bilderna utvärderas av läkare för att patienten ska få rätt diagnos. För att läkaren ska kunna göra en korrekt bedömning av bilden och därmed ge patienten den behandling som situationen kräver måste bilden vara rättvisande och vara av sådan kvalitet att alla viktiga detaljer går att urskilja. Bildkvalitet är ett ganska diffust begrepp och ofta används subjektiva bedömningsmetoder för att bestämma ifall en bild är bra eller dålig.

En modern grafikprocessor är oerhört kraftfull och har en prestanda som potentiellt sett är många gånger högre än för en modern mikroprocessor. I takt med att grafikprocessorn blivit alltmer programmerbar har det blivit möjligt att använda den för beräkningstunga tillämpningar utanför dess normala användningsområde. Inom det här arbetet utreds vilka möjligheter och begränsningar som uppstår vid användandet av grafikprocessorer för generell programmering. Arbetet inriktas främst mot signal- och bildbehandlingstillämpningar men mycket av principerna är tillämpliga även inom andra områden.Ett ramverk för bildbehandling implementeras och några algoritmer inom bildanalys realiseras och utvärderas, bland annat stereoseende och beräkning av optiskt flöde. Resultaten visar på att vissa tillämpningar kan uppvisa en avsevärd prestandaökning i en grafikprocessor jämfört med i en mikroprocessor men att andra tillämpningar kan vara ineffektiva eller mycket svåra att implementera..

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.

The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.

The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).

The aim of this Master's thesis is to analyze the relation between the discursive formation and the optical formation in the public library-apparatus. An ongoing individualization process in the library field and in society at large is used as a backdrop in the analysis. Discourse analysis is used as a method to explore the main Swedish library periodicals Biblioteksbladet, Bibliotek i Samhälle and DIK-forum. All issues from the years 1999 and 2009 have been used as material. The main analytical instruments applied in the analysis of this material are Michel Foucault's terms dispositive, apparatus and diagram.
