Netadmin Systems är ett Linköpingsbaserat IT-företag där huvudprodukten NETadmin är ett Operation support system/Business support system (OSS/BSS) som i huvudsak används i öppna nät för bl.a. kund- och lagerhantering, provisionering, övervakning och ärendehantering. Ett växande behov finns att göra det möjligt att använda övervakningssystemet via mobila enheter för att kunna felsöka och hantera driftstörningar effektivt.Syftet med rapporten är att undersöka hur övervakningssystemet kan göras tillgängligt på Android samt att ta fram en prototypapplikation för hantering av grundläggande övervakning. Genom fallstudien som har genomförts har slutsatsen dragits att Netadmin API är lämpligt för kommunikation via mobila enheter men att API behöver vidareutvecklas med ytterligarefunktioner. De viktigaste av dessa har implementerats och arbetet har även mynnat ut i en applikationsprototyp för Android.Genom utvecklingen av denna applikation ges Netadmins kunder möjlighet att hantera övervakningssystemet via mobila enheter..
Deaktivering av metanisering katalysatorer
A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.
Utvärdering av VAV i nybyggt kontorshus
VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.
Mean value modelling of a poppet valve EGR-system
Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.
Validering av glidande statorfötter på Hissmofors G6 och G7
Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.
"Vi kunde ha varit bättre..." : En fallstudie om internkontroll i Sverige
???This study has been made with the purpose of gaining an understanding of how a Swedish company may think and act concerning their internal control. An American body, COSO, have for some time published documents containing guidelines for how companies should go about this process, however, when conducting this study we were not aware of the extent to which companies in Europe and mainly Sweden used them. In order to learn about this, and also to gain an understanding of when these guidelines are appropriate, we conducted a case study with a large-sized, multinational Swedish company. We also conducted an interview with an expert in internal control monitoring, Anna-Clara af Ekenstam of Pricewaterhouse Coopers, in order to get the perspective of the evaluators in this process and to gain some insight as to whether our case is typical in Sweden or not. We found that our company disregards certain aspects of internal control condoned by COSO, while performing better on other dimensions.
Att göra tillit : Hur tillit skapas i interaktionen mellan människor
The purpose of this essay is to examine the origin of generalized trust. We compare existing theories on trust to determine what approach is more fruitful in explaining the prevalence, or absence, of trust. Our conviction is that trust should be viewed as an interaction, rather than a disposition or a rational choice. The sample is based on the countries of the OECD. In total, five different hypotheses are tested: i) that generalized trust is created by equal distribution of income, ii) that generalized trust is created through monitoring of the state, iii) that generalized trust is created through rule by law; iv) that generalized trust is created when the welfare apparatus is guided by principles of universalism; or iv) that generalized trust is created when the state integrates trust networks.
Habitatval, migrations- och furageringsaktivitet samt homing hos gädda (Esox lucius) härstammande från Österby myr, Gotland.
In this study the spawning migration activity, habitat choice (depth and temperature), foraging activity, duration of stay in the spawning site and homing-behavior was studied for anadromous pike (Esox lucius) in the wetland Österby myr, Gotland.The spawning migration was concentrated to dusk and dawn, a homing behavior was confirmed and there was no significant difference between sexes with respect to duration of stay. A difference in habitat choice and small variation in foraging activity between individuals was established..
detection and quantification of almond (Prunus dulcis) in food with ELISA
Reliable methods to analyze food for the presence of almond are important ? not only for those allergic to almond, but also for monitoring the compliance with labelling regulations (EG directive 2003/89). Until now the Swedish National Food Administration has used methods like rocket immunoelectrophoresis and real-time PCR to detect almond in food. These methods are, however, not sensitive enough for protecting the most sensitive individuals. Therefore, the performance of a commercial ELISA kit was tested with regard to specificity/cross reactivity and limit of detection for almond both in solution and in different matrixes.The limit of quantitation was at least 3,1 ppm (mg/kg) in solution and similar concentrations were measured in bisquits and chocolate.
Övervakning : av servermiljöer
Övervakning används för att granska IT-infrastrukturen, för att hitta och varna på de fel som kan uppstå i systemen. Allt för att minimera den ständiga risken att det kan sluta fungera. Dagens verksamheter blir allt mer beroende av sin IT och många företag står helt stilla idag om deras IT-system inte fungerar, detta kan leda till stora kostnader och förlorad intäkt.Utredningsdelen innehåller fyra stora delar. Delarna innefattar vad övervakning är, varför övervakning används, vad som övervakas och hur övervakningen går till.För att samla mer information samt att bekräfta utredandeavsnittet ställdes ett antal frågor till Idenet AB, Högskolan Kristianstad, LanGate System AB och QSi Sweden AB i form av intervjuer. Intervjuerna ligger till grund för genomförandedelen av arbetet.

Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Kvalitetssäkringsproblematik i den privatiserade svenska familjerådgivningen
The purpose of this article is to examine issues concerning quality assurance in the Swedish family counselling. To obtain the purpose following factors have been analysed: what kind of requirements/criteria are put on the companies/practitioners, what the respondents think about the lack of common standards and criteria and their opinions concerning ?Lagen om valfrihetssystemet?. Monitoring of criteria, privatisation and increased competition are other factors that have been analyzed. The material was obtained from the family counsellors own association and was analyzed in the light of previous research and theories regarding the quality of family counselling however we also considered theories about quality within social work in general.
Klinisk termografi som diagnostiskt hjälpmedel vid rörelsestörning hos häst :
Thermography is the assesment of the surface temperature of the horses body and it falls into the categori of physiological imaging. Thermography allows us to portray inflammation and changes in sympathetic tone in a graphical manner.
The purpose of this study was to review thermography in equine medicine and to evaluate thermography as an aid in the diagnosis of lamness in horses.
Thermography has been helpful to identyfy sprains, stress fractures, shin splints and soft tissue, tendon, ligamentous and nerv injuries and to monitor healing processes during rehabilitation. Routine thermography may reveal inflammatory responses prior to clinical signs.
In present study thermograpy gave especially valuabel information in two cases. In one horse reduced blood flow in a. saphena due to a thrombosis were visualised and in the other horse bilateral thoracolumbal radiculopati was diagnosed.
