The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .

Temperaturmätning på gris - en jämförelse mellan infrarödmätning på hud och rektaltemperatur

Under en tidsperiod på tretton veckor mättes temperaturen på tvåhundratjugo suggor och etthundraåttiotre smågrisar i grisningsboxar vid SLUs forskningsanläggning. Vid varje mätningstillfälle mättes rektaltemperatur samt hudtemperatur på tryne, öra, bog, länd och vulva. Varje mätområde på huden mättes tre gånger vid ett mättillfälle, två olika IR-termometrar användes. Detta innebar totalt ettusen etthundra enskilda mätningar på suggor och niohundrafemton mätningar på smågrisar. som samlades in och analyserades avseende korrelation mellan de olika mätområdena på huden och rektaltemperaturen.

Milk yield and composition in Swedish landrace goats (Capra hircus) kept together with their kids in two different systems

Swedish goats are mainly held for cheese production and therefore, both milk quality and composition are of great importance for dairymen. Today, only few data exists on milk composition from Swedish dairy goats and the casein content is still unknown. One way to reduce the work load for goat farmers and increase animal welfare can be to keep goats and kids together for longer periods. The aims of this study were to investigate how milk yield and composition were affected when kids suckled their dams during 8 weeks, and to measure the casein content on farm level by a mid-infrared spectroscopy method, previously calibrated for goat milk. Lactating goats were kept in two different MIX- systems where the dams are both suckled and milked.

Du kan smärtlindra lätt med en smärtskattning som är rätt - En litteraturstudie om smärtskattning hos äldre

Sjuksköterskan har ett stort ansvar när det gäller patienters smärtlindring då det är sjuksköterskan som bedömer smärtan efter att patienten fått skatta den på exempelvis en smärtskattningsskala. I vården idag sker missuppfattningar om äldre patienters förmåga att känna smärta och sjuksköterskan har en tendens att bedöma smärtan mildare än vad den är. Syftet med denna litteraturstudie är att finna och beskriva smärtskattningsskalor som är lämpade för äldre patienter samt att jämföra smärtskattningsskalorna med varandra. Resultatet visar att patienter med viss grad av kognitiv nedsatthet har förmåga att bruka en smärtskattningsskala och att den skala som har bäst reliabilitet, genomförbarhet och som föredras mest är Iowa Pain Thermometer (IPT). Den minst föredragna skalan hos äldre och den som har sämst validitet, reliabilitet och genomförbarhet är Visual Analoge Scale (VAS)..

Analys av molnklotter inom det termala infraröda våglängdsområdet med IRST-data

Detta arbete har utförts tillsammans med FOA 3 i Linköping som en undersökning av molntextur och molnklotter i flygbilder som registrerar värmestrålning. I dessa sammanhang betyder klotter en slags spräcklighet i bilden, eller att det inte går att se några mönster och strukturer i den..

Dömd för brott? Sambandet mellan intagnas implicita och explicita attityder till brott och kriminell belastningsgrad

According to statistics two thirds of Swedish criminals relapse into crimes within three years (Brå, 2007). Researchers suggest a relationship between attitudes toward crime and delinquent behaviour (Andrews & Bonta, 2003), but whether these attitudes are implicit or explicit remains unclear. Therefore, the aim of this study was to measure both constructs. Using SC-IAT (Karpinski & Steinman, 2006) and constructs from the Theory of planned behavior (Ajzen, 1985), criminals (N = 51) in three different prisons in southern Sweden were tested. Analysis yielded mixed results.

Spöa, sparka, slå och strypa: Kriminellas våldsattityder avslöjas med implicita mätningar

Attitudes towards violence were assessed using both implicit (The Single Category Implicit Association Test; Karpinski & Steinman, 2006) and explicit measurements (a Feeling Thermometer). A group of criminals showed more positive explicit and implicit attitudes towards violence than a group of non-criminals. In addition, The Aggression Questionnaire (Buss & Perry, 1992) revealed significant differences in aggression between the groups; criminals' mean scores were higher on all four subscales (physical aggression, verbal aggression, anger and hostility). Furthermore, significant correlations were found between all the measures, including the implicit and explicit attitude measures. The findings support the validity of the SC-IAT as an implicit measure of violent attitudes.

Egyptens balsameringsteknik : en kemisk analys av organiska lämningar

This paper deals with the embalming process in ancient Egypt. Samples were collected from six objects from Medelhavsmuseet in Stockholm. The objects were one supposed ladle and five different contents from pottery. Fourier transform infrared spectrometry (FTIR) and gas- chromatography/mass spectrometry was used to characterize the components of the materials. The result was then correlated with previously made analysis of embalming materials to discover similarities.

Optimerade material för optiska komponenter i koncentrerande solfångare

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

Tidsberoende kvantkemiska beräkningar av optisk absorption hos polymerer och molekyler med litet bandgap

The vertical electronic excitation energies for the narrow-bandgap polymers LBPF, EP37 and EP62 have been calculated using Density Functional Theory (DFT). Also the vertical excitation energies for the acceptor unit of LBPF have been calculated using the Hartree-Fock (HF), DFT and Coupled Cluster (CC) methods. The calculations cover the visible and infrared wave length region and two strong transitions are obtained, one corresponding to the pi to pi* transition and one corresponding to the pi to Acceptor transition. The excitation energies obtained from DFT are below the corresponding experimental results and attempts have therefore been made to perform bench-marking calculations using a hierarchy of CC methods..

Avståndsmätning med Hög Noggrannhet till Låg Kostnad

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

Interaktionskvalitet - hur mäts det?

Den tekniska utvecklingen har lett till att massiva mängder av information sänds, i höga hastigheter. Detta flöde måste vi lära oss att hantera. För att maximera nyttan av de nya teknikerna och undkomma de problem som detta enorma informationsflöde bär med sig, bör interaktionskvalitet studeras. Vi måste anpassa gränssnitt efter användaren eftersom denne inte har möjlighet att anpassa sig till, och sortera i för stora informationsmängder. Vi måste utveckla system som gör människan mer effektiv vid användande av gränssnitt. För att anpassa gränssnitten efter användarens behov och begränsningar krävs kunskaper om den mänskliga kognitionen.

Energieffektivisering av arbetsbodar på byggarbetsplatser

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.
