    Making MLSD-decisions on some individual symbols thresholding the matched filter output1997In: Proceedings: 1997 IEEE International Symposium on Information Theory : Maritim Hotel and Congress Center, Ulm, Germany, June 29 - July 4, 1997, Piscataway, NJ: IEEE Communications Society, 1997, p. 75-Conference paper (Refereed)
    Abstract [en]

    We present a detector that, by thresholding the output of the matched filter, gives MLSD-decisions on binary, antipodally modulated symbols that have been corrupted by intersymbol interference and additive Gaussian noise. The detector is simple in structure, consisting of a whitened matched filter and two variable thresholds for each symbol to be detected. The detector will make decisions on some, but most often not all, of the symbols in a transmitted sequence, and those decisions will be the same decisions as the maximum likelihood sequence detector (MLSD) would have made. The number of symbols that are detected is stochastic, varying from sequence to sequence. The basis of the detector is a bound on a cross-product of the quadratic form in the log-likelihood function for the transmitted sequence

    Making MLSD decisions using a data-dependent threshold device1996In: Proceedings of the 1996 SNRV and NUTEK Conference on Radio Sciences and Telecommunications in Luleå and Kiruna June 3-6, 1996: RVK 96 / [ed] Lars H. Zetterberg, Luleå: Luleå tekniska universitet, 1996, p. 245-249Conference paper (Refereed)
    Abstract [en]

    This paper presents a detector for obtaining MLSD decisions on binary symbols that has been corrupted by intersymbol interference and additive Gaussian noise. The basis of the detector is a bound on a cross-product of the quadratic form in the log-likelihood function for the transmitted sequence. The detector will only make decisions on some of the symbols in a transmitted sequence, but those decisions will be the same decisions as the MLSD would have made. The number of symbols to be detected is stochastic, varying from sequence to sequence. The detector is simple in structure, consisting of a whitened matched filter and two variable thresholds for each symbol to be detected. Because the detector in general does not detect the complete sequence of symbols, but has a very good performance on those symbols that are detected, it is suitable as a complement to some existing detector that is inferior to the maximum likelihood sequence detector.

    When are the MLSD respectively the matched filter receiver optimal with respect to the BER?1995In: Proceedings: 1995 IEEE International Symposium on Information Theory, Whistler, British Columbia, Canada, 17 - 22 September, 1995, Piscataway, NJ: IEEE Communications Society, 1995, p. 331-Conference paper (Refereed)
    Abstract [en]

    We reconsider the minimum/optimal bit-error probability receiver (OBER) for intersymbol interference channels with Gaussian noise and the reception of finite blocks of bits. We view the OBER as a function with two inputs: the received sequence and an expected signal-to-noise ratio; and one output: the estimated block of bits. Assuming that all sequences are equally probable to be transmitted we prove two results about the behaviour of the OBER. We show that the OBER coincides with the maximum likelihood sequence detector (MLSD) when designed for high signal-to-noise ratios and that it collapses to a matched filter followed by a hard-limiting device for low expected signal-to-noise ratios

    A reduced complexity viterbi equalizer used in conjunction with a pulse shaping method1992In: Proceedings of Nordic Radio Symposium: NRS 92 : wave propagation, personal, mobile and satellite communications / in co-operation with AUC - Aalborg University / [ed] Chr. Christensen, Aalborg: Aalborg University , 1992, p. 91-94Conference paper (Refereed)
    Abstract [en]

    The complexity of the Viterbi algorithm can be reduced by linear pre-equalization. We introduce a linear preprocessor using the weighted least squares filtering of [10]. The geometric technique of L.Barbosa [3] is evoked for analytical representation of the complexity reduction by pre-equalization, and for evaluation of error performance. We give results on the bit error rate of the WLS preprocessor and of the linear preprocessor of Falconer and Magee [6].

    Pedagogers tankar om bild i förskolan: En studie om bildens syfte och barns bildskapande utveckling i förskolan2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att öka förståelsen av bildskapande i förskolan utifrån pedagogers perspektiv. Jag ville ge en inblick i hur pedagoger ser på bildskapandets betydelse i förskolan samt undersöka hur pedagoger i förskolan förhåller sig till bildarbete och barns bildskapande. De tre frågeställningar som ställdes var: Hur beskriver pedagogerna arbetet med bild i förskolan?, Vad vill pedagogerna uppnå med bild i förskolan? och Hur beskriver pedagogerna barns bildskapande utveckling? För att besvara forskningsfrågorna användes en kvalitativ intervjuteknik kallad halvstrukturerad livsvärldsintervju. Totalt sju pedagoger intervjuades. Resultatet visade att pedagogerna beskrev arbete med bild som en kompromiss mellan deras visioner och de hinder ramfaktorer innebar. Fem olika målsättningar med bild lokaliserades varav flest pedagoger uttryckte att bildens målsättning var att utveckla barns bildskapande och att barnen skulle uppnå känslomässiga mål. Pedagogerna hade olika uppfattningar om barns bildskapande utveckling, tre kategorier kunde lokaliseras beroende på vilken orsak pedagogerna framhöll att bildskapande utvecklingen hade sin grund i. Dessa var: inifrån, socialt samt inifrån och socialt. Min studie visar att många faktorer påverkar bildskapande arbete i förskolan. Pedagoger har personliga teorier om barns bildskapande samt olika målsättningar med bildarbete i förskolan och dessa tillsammans med ramfaktorer påverkar hur arbetet med bild ser ut.

    Data transfer over high latency and high packet loss networks2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to pin down which aspects aect the data transfer speed through the Internet, especially with regard to latency and packet loss. What is required from a technical point of view in order to effciently mitigate the effects of latency and packet loss to network transfer? What are the diffculties when testing network protocols? The approach is to test four different protocols; TCP CUBIC, Westwood+, Tsunami, and UDT, while gathering metrics such as throughput, the size of the congestion window and slow start threshold, and then analysing the results. The analysis of the results show that latency have the most impact on throughput, effecting the network transfer by decreasing the number of times the congestion window is able to grow in RTT dependant algorithms, effectively decreasing the throughput. Packet loss eects network transfer because protocols interpreting the loss as a congestion problem on which the protocol decreases the sending rate. The size of this decrease is shown to impact the throughput, where an aggressive decrease shows a poorer performance with packet loss. The study can aid anyone who seeks to develop a network transport protocol.

    Is there a correlation between the nutrient content and variation in the HvNAM-2 gene in Hordeum vulgare?2015Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Barley is one of the most important cereal crops in the world and a better understanding of the factors that regulates the nutrient content in the grain is of high interest. The industrial breeding during the last century has led to bigger yield but possibly a decrease in nutrient content. In wheat, the NAM-B1 gene is a well-studied gene that affects the grain protein and micronutrient content. Two orthologue genes in barley HvNAM-1 and HvNAM-2 are candidate genes to play a similar role in the barley senescence process.

    I have looked for a correlation between the diversity in the HvNAM-2 gene and nutrient content in 37 Nordic barley accessions. The samples were sequenced and then aligned and analyzed for variation. I found three haplotypes which were compared in nutrient content and in micronutrient content. No significant difference between the haplotypes was found, which can be due to small sample size or that no correlation exists between the grain protein content and the HvNAM-2 gene variation. Significant correlation was however found between the nitrogen content and the micronutrient contents that indicate that the pathways of all the nutrients’ mobilizations are tightly coupled. For future research a bigger number of accessions, preferably at least 100, need to be analyzed to be able to give any conclusions. The molecular mechanisms in the cells during senescence also need further investigation.

    Abstract [sv]

    Att vi dagsläget diskuterar Public Private Partnership, beror till stor del på att vi i Sverige just nu har en mycket dålig tillväxt, klart är att läget är akut och att tillväxten behöver komma igång snarast. För att finna lösningar på tillväxtproblematiken måste staten våga pröva på olika finansieringsalternativ som gagnar den lokala och regionala tillväxten i landet.

    Finns Östtimor på världskartan?: om media och ideologi1994Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Denna uppsats vill belysa mediers betydelse och påverkan i USA och väst- länderna samt vilka vilka konsekvenser detta får för människorna, samhället och världen. Mediernas roll som en del i den västerländska ideologin samt mediernas påverkansmöjligheter lyfts fram. De teorier som ligger till grund är Noam Chomskys propagandamodell, kritisk teori, kultiveringsteorin och dagordningsfunktionen. Teorierna belyser medier på individnivå, samhällsnivå och den globala nivån. Mediernas roll belyses genom mediernas förhållningssätt till Indonesiens invasion av Östtimor den 7 december 1975 som fortfarande pågår. En undersökning görs vad som skrivits i Dagens Nyheter och Svenska Dagbladet om Östtimor under vissa tidsperioder i samband med speciella händelser i Östtimor. Utifrån det görs en analys av svenska mediers inställning till kriget i Östtimor.

    Omvårdnad vid höftfraktur2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund:

    Patienter med höftfraktur blir allt fler i takt med att medelåldern ökar. Det är en stor och resurskrävande patientgrupp. De har under en längre tid varit underprioriterade vilket har resulterat i långa väntetider till operation.

    Syfte:

    Syftet var att beskriva om det fanns några fördelar att arbeta med höftspår vid höftfrakturer samt att beskriva urvalet av de använda vetenskapliga artiklarna.

    Metod:

    Deskriptiv litteraturstudie med tretton vetenskapliga artiklar med kvalitativ och kvantitativ ansats. Likheter och olikheter i artiklarnas resultat har kategoriserats och sammanställts till fem olika teman.

    Huvudresultat:

    Resultatet visade att det fanns fördelar med att arbeta med omhändertagande via höftspår, detta resulterade i kortare väntetid till operation samt färre komplikationer. Dessa patienter som omhändertogs via höftspår hade även en kortare vårdtid. Risken för mortalitet påverkades inte nämnvärt vid höftspår kontra konventionell vård vid höftfraktur.

    Slutsats:

    I kategorien förkortad tid till operation samt kortare vårdtid kan man se stora positiva skillnader efter införandet av höftspår, i minskade postoperativa komplikationer en viss förbättring. I kategorin minskad risk för dödlighet ses ingen statistisktsignifikant skillnad. Riktlinjerna kring detta höftspår har påverkat omvårdnaden i en positiv riktning. Dessa patienter omhändertas nu med en snabbare och bättre rutin. Det har inte upptäckts några nackdelar med att arbeta med höftspår.

    Virtual instrumentation: Introduction of virtual2007Independent thesis Basic level (professional degree), 20 points / 30 hpStudent thesis
    Abstract [en]

    The Large Hadron Collider (LHC) is the next large particle accelerator developed at CERN, constructed to enable studies of particles. The acceleration of the particles is carried out using magnets operating at about 1.9 K, a temperature achieved by regulating flow of superfluid helium. For economical reasons, control of the helium flow is based on feedback of virtual flow meter (VFT) estimates instead of real instrumentation.

    The main purpose of this work is to develop a virtual flow meter with the possibility to estimate the flow by means of two different flow estimation methods; the Samson method that has previously been tested for the LHC, and the Sereg- Schlumberger method that has never before been implemented in this environment.

    The virtual flow meters are implemented on PLCs using temperature and pressure measurements as input data, and a tool for generating the virtual flow meters and connect them to the appropriate physical instrumentation has also been developed.

    The flow through a valve depends, among others, on some pressure and temperature dependent physical properties that are to be estimated with high accuracy. In this project, this is done by bilinear interpolation in twodimensional tables containing physical data, an approach that turned out to be more accurate than the previously used method with polynomial interpolation.

    The flow measurement methods have been compared. Since they both derive from empirical studies rather than physical relations it is quite futile to find theoretical correspondencies, but the simulations of the mass flows can be compared. For low pressures, the results are fairly equal but they differ more for higher pressures. The methods have not been validated against true flow rates since there were no real measurements available before the end of this project.

    ISP och uppsats. En kvalitativ studie av Kuhlthaus informationssökningsprocess bland uppsatsskrivande högskolestudenter.2000Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The main purpose of this thesis is to examine whether the ISP (the Information Search Process) as defined by Carol Kuhlthau is applicable to Swedish University students. Qualitative interviews were carried out with students enrolled in their thesis course at the end of their university education. The selection is based on convenience sample of students visiting the university library. The questions are mainly about how to find out the experiences of the students when they look for documents at the beginning of their thesis work. Other relevant questions are about user-education, information literacy and what the students' opinions are concerning a thesis as a part of their education. The result of the study is presented in two parts. The first in relation to Kuhlthau's ISP and the second part to other relevant questions. The ISP can be identified with small deviations from the way Kuhlthau defines it. The other part of the result tells us that the information literacy among our students is not what we would like it to be.

    Grönt bränsle i Västerås kommun2002Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This report deals with what the effect would be if the municipality of Västerås changed theirway of producing energy, to hopefully reduce the amount of pollution. An ex antecomparison of two alternatives/scenarios for the projected situation in year 2013 isperformed. The reason for this is that Målbild Västerås (a vision for the city of Västerås)deals with that year. The first alternative, called the zero alternative, shows how big theemissions would be if the power plant continued to produce energy by the burning of coaland oil. The other alternative, called the green fuel, describes how the big the emissionswould be if the power plant substitutes some of the coal with a locally grown energy cropcalled Salix. Emissions that have been treated in this report have been limited to covercarbon dioxide and nitrogen emissions.

    When Salix is produced it is impossible to harvest every year, but every 3-5 years dependingon the weather and location of the field. Because of that both the results from harvestingevery third year and harvesting every fifth year are shown in the report. To get a bettercomparison between the two alternatives the growing of regular crops has been included inthe zero alternative.

    You can clearly see that great environmental profits in NOx and carbon dioxide can begained by introducing the bio fuel. Carbon dioxide emissions are reduced by more than 100times in such a alteration. NOx emissions are between 4-6 times lower in the bio fuelalternative than in the zero alternative. In all calculations though there are an uncertaintywith varying size. With this uncertainty in mind you should be careful before to largeconclusions are drawn from the reduction of NOx emissions. I you look at the emissionswithin Västerås municipality the emissions are lowered in both alternatives, but still you cansee that introduction of the bio fuel clearly has the lowest emissions compared to the zeroalternative.

    Varför sågas så lite björk i Sverige?: Why isn't more birch wood being sawn in Sweden?2009Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Summary in English

     

    Sweden is a forest country with a standing wood balance of more than 3 000 million m3sk. Pine and spruce are dominating species but there is also a wood balance of some 420 million m3sk of birch. Birch is offering excellent timber properties and is well matching both pine and spruce with the exception of its sensitivity to moisture. Despite of this, quite small quantities of birch timber are being used in Sweden. Most birch wood being cut is used for the production of paper and pulp (95%). Although the birch tree is an old species in Sweden it was during the 2000th century until the end of the 1970s treated as a weed and was struggled with by means of herbicides. Subsequently Sweden lost knowledge and experience in how to deal with this wood which in turn leads to a poor quality of now existing clumps of birch trees. Compared to coniferous trees little research has been done of broadleaf trees but it’s anyhow known that the clearing and thinning of birch trees have to be stricter than that of softwood. Birch trees have an interesting potential with a shorter production cycle than pine and spruce. Used for timber the yield for the forest owner could be quite interesting. Broadleaf trees are also playing an important role to improve the overall environment.

     

    To increase the use of birch wood more information about this specific timber has to be spread to all parties concerned. That involves owners of forest land, silviculture, sawmills, industry and distributors. Activities along the chain of actors have to be market oriented and include economic incentives for parties concerned. To be able to increase the volume of birch timber used new areas of deployment have to be found outside the traditional production of furniture etc. An interesting area is then the building industry.

    Tillit eller politiska åsikter: Vad som styr kommunala chefstjänstemäns beteenden, prestation och engagemang på arbetet2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande uppsats är att undersöka om kommunala chefstjänstemän som delar politisk åsikt med kommunens styrande politiker i högre utsträckning än andra chefer också ”gör det lilla extra” på arbetet. Syftet är även att se om det är tillit till de styrande politikerna snarare än politiska åsikter som är viktigast för att förklara benägenheten att göra det lilla extra på arbetet. Detta undersöks genom att studera beteenden, prestation och engagemang på arbetet. Urvalet bestod av chefen för utbildningsförvaltningen (eller motsvarande) i Sveriges samtliga kommuner och undersökningen baserades på data insamlat med hjälp av webenkäter under hösten 2014. Av logistiska regressionsanalyser framgår att det verkar vara tillit till styrande politiker snarare än politiska åsikter som styr kommunala chefstjänstemäns benägenhet att göra det lilla extra på arbetet. Detta ger stöd åt teorin om socialt utbyte, d.v.s. att chefstjänstemännen ”i utbyte” mot politikers hänsyn och omtanke, utför beteenden som går i linje med politikernas preferenser. Det är dock möjligt att kommunala chefstjänstemän utnyttjar sin makt över politiska processer för att gynna preferenser som inte är kopplade till politisk syn. Det kan exempelvis handla om att gynna andra gruppers preferenser eller att förbättra vissa gruppers position i samhället. Det är ett uppdrag för framtida forskning att undersöka om så är fallet.

    Optimization Driven Development of Stringer to Leisure Boat2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The increasing demand for products of light weight and high performance to be produced and developed in shorter periods of times has put high pressure on the product development process. Much research is done in order to find ways on how to speed up this process at the same time as delivering products of higher quality to the customer. Much of the literature focuses on how important it is to “tear down the walls” between departments at a company by integrating as much different knowledge as early in the process as possible. Thereby, much of the costly problems found late in the process can be avoided leading to shorter development times and cost savings.

    Commonly companies use simulation software to verify their final designs before the products pass forward to prototyping and test production. In some cases products need to be redesigned and big changes of the product geometry might be necessary which often is very costly in such a late stage of the process.

    Eker Design in Fredrikstad, Norway, wants to investigate the potential of using simulation driven design in an early stage of the product development process. In order to make this investigation this exam work has been carried out on a real design case by the development of a new “stringer” totally from scratch. A stringer is what gives rise to the stiffness of the boat and is a structure mounted in-between the hull and the deck. The stringer was developed to the Hydrolift SX22 leisure boat by using simulations and topology optimization software as the driving force for the design. The research questions to be answered were:

    • Is it possible to develop a stringer through a design process based on topology optimization and simulation software with equal performance as the existing stringer?
    • How does the optimized result perform in comparison to the existing stringer?
    • Can any weight reduction be achieved with a new stringer design?

    In the end of the work the existing stringer and the new stringer design was compared and evaluated. The results showed that the new stringer with a weight reduction of 30% performed very well in comparison to the existing one. This proves that the topology optimization and simulation driven design process beneficially can be used in marine architecture. It has also proven to be an efficient method to lower the material usage and increase the strength of the stringer.

    Energy-dense meals improve energy intake in elderly residents in a nursing home2003In: Clinical Nutrition, ISSN 0261-5614, E-ISSN 1532-1983, Vol. 22, no 2, p. 125-31Article in journal (Refereed)
    Abstract [en]

    Background: Several studies have shown that malnutrition is common among nursing home residents.

    Aim: We hypothesized that addition of natural energy-dense ingredients to a standard diet would improve voluntary energy intake and ability to perform activities of daily living (ADL) and decrease infections in elderly residents under nursing home care.

    Methods: Thirty-five residents in a municipality nursing home (median age 83 years) were served either a standard diet (1600 kcal/day) (control group, n=18) or the same meals fortified with natural energy-dense ingredients (2100 kcal/day) (experimental group, n=17). Energy intake and ADL function were measured before and after the intervention. All episodes of infection were registered. Non-parametric statistics were used.

    Results: Energy intake increased in the experimental group from 23.5 (21.3-28.5) kcal/kg/body weight before, to 31.9 (29.7-33.7) kcal/kg/body weight during the intervention (P<0.001). There was no change in energy intake in the control group. ADL function in the experimental group was unchanged, while it decreased significantly in the control group (P<0.001). The number of infections tended to be lower in the experimental group than in the control group (5 vs 13). The cost for the energy-dense ingredients was approx. 0.11 EUR per resident and day.

    Conclusions: Addition of natural energy-dense ingredients to regular meals is an inexpensive way to improve voluntary energy intake in elderly nursing home residents, a treatment that was accompanied by maintained ADL function.

    Minimal effect on energy intake by additional evening meal for frail elderly service flat residents: a pilot study2008In: The Journal of Nutrition, Health & Aging, ISSN 1279-7707, E-ISSN 1760-4788, Vol. 12, no 5, p. 295-301Article in journal (Refereed)
    Abstract [en]

    Background: Nutritional problems are common in frail elderly individuals receiving municipal care.

    Objective: To evaluate if an additional evening meal could improve total daily food intake, nutritional status, and health-related quality of life (HRQOL) in frail elderly service flat (SF) residents.

    Design: Out of 122 residents in two SF complexes, 60 subjects agreed to participate, of which 49 subjects (median 84 (79-90) years, (25th-75th percentile)) completed the study. For six months 23 residents in one SF complex were served 530 kcal in addition to their regular meals, i.e. intervention group (I-group). Twenty-six residents in the other SF building were controls (C-group). Nutritional status, energy and nutrient intake, length of night time fast, cognitive function and HRQOL was assessed before and after the intervention.

    Results: At the start, the Mini Nutritional Assessment classified 27% as malnourished and 63% as at risk for malnutrition, with no difference between the groups. After six months the median body weight was unchanged in the I-group, +0.6 (-1.7-+1.6) kg (p=0.72) and the C-group -0.6 (-2.0-+0.5) kg (p=0.15). Weight change ranged from -13% to +15%. The evening meal improved the protein and carbohydrate intake (p<0.01) but the energy intake increased by only 180 kcal/day (p=0.15). The night time fast decreased in the I-group from 15.0 (13.0-16.0) to 13.0 (12.0-14.0) hours (p<0.05). There was no significant difference in cognitive function or HRQOL between the groups.

    CONCLUSION: Nine out of ten frail elderly SF residents had nutritional problems. Serving an additional evening meal increased the protein and carbohydrate intake, but the meal had no significant effect on energy intake, body weight or HRQOL. The variation in outcome within each study group was large.

    Energyenriched hospital food to improve energy intake in elderly patients1996In: JPEN - Journal of Parenteral and Enteral Nutrition, ISSN 0148-6071, E-ISSN 1941-2444, Vol. 20, no 2, p. 93-97Article in journal (Refereed)
    Abstract [en]

    Background: It was hypothesized that energy intake in hospitalized elderly patients could be improved by increasing the density of energy of the food and that the volume of food actually consumed, even with a higher energy content than the normal, would not change with servings of high energy-dense hospital food. Methods: Thirty-six elderly patients (52 to 96 years) of both sexes, long-term treated at two comparable wards, participated in this study. The patients were given 6 weeks of regular hospital food (RHF, 1670 kcal/d, 7.0 MJ) and 6 weeks of high-energy food (HE, 2520 kcal/d, 10.5 MJ). The volume of food was kept constant. A crossover study design was used. Food intake, energy intake, body weight, and modified functional condition (Norton scale) were measured. Results: Regardless of type of food (RHF or HE) and time of day (lunch or dinner), the food portion size (volume of food) intake was the same, approximately 80% of the portions consumed. HE led to a 40% increase in energy intake (from 25 ± 1 during RHF to 35 ± 2 kcal/kg/d, p <.0001), which resulted in a 3.4% increase in body weight (p <.001) after 3 weeks of HE. Only minimal changes in functional condition were found. The cost of HE was substantially lower (-85%) than any other mean available for improvement of energy intake. Conclusions: A significant increase in energy intake can be achieved by higher energy density in regular hospital food and that HE does not cause a decrease in the volume of the food consumed. These findings suggest that it is the volume of food rather than the energy that limits voluntary energy intake of hospital food in elderly hospitalized patients.

    Abstract [en]

    Our modern World is filled with information everywhere. Information isconstantly processed, stored and communicated. However,we all know that information usuallyhas some value;therefore,we build secure and complex systems, whichare packed with data. Valuable data. Then we put humans behind those systems and introduce ahuge vulnerability and by that,we are risking our data falling into the wrong hands. Social engineering –it is used to deceive people and letting themgive up sensitive information.

    This qualitative interview study will attempt to disclose the perception of social engineering from people who perform penetration-testingservices.

    The results of the study are showing that participators are partially decided of their view of social engineering. They almost all agree that “phishing” is a common attack in bothinternet occurrences and in work-related matters. Furthermore, the conclusion shows that the psychological aspect of social engineering is an important improvement area.

    Lastly, the participants explain several preventative actions, whichcan be used by organizations and by individuals to minimize the risk of exposure to social engineering.

    Begreppsanvändning inom missbruksvården: Granskning av tre centrala begrepp2009Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study aims to examine possible differences in the use of three central concepts (substance abuse, heavy substance abuse and open care) within the substance abuse care. The issues addressed are (I) how is the three central concepts used in texts about substance abuse care? (II) if differences exists in the use of the three central concepts, which similarities and differences can be found? (III) how can the use of the three central concepts be understood from the basis of social constructionism? The study is a literature review and the results have been analyzed on the basis of social constructionism. The result indicates that differences in the concept handling occur. Differences in definitions of substance abuse is seen through that certain definitions treat consumption patterns while others definitions mean that it should be seen as deviance. Similarities can be seen as the majority of definitions around substance abuse concern consequences of the use. The use of the concept “heavy substance abuse” concerns mainly demarcations between drug abuse and heavy drug abuse. The concept handling of open care is coherent in the case of its extraneous framework however differences are found when it comes to how extensive the concept should be.

    Abstract [en]

    In 1 Corinthians we find two much discussed passages which, focusing especially on the women, speak of order at the Christian gatherings: 11:2-16 and 14:34-36. This paper analyses these passages and their treatment in the scholarly literature. How should one relate to the fact that competent scholars reach diametrically opposed conclusions? Is there error in the argumentation, the premises, or do we simply lack sufficient knowledge? Is it possible to distinguish between what is contested for exegetical and for theological reasons?

    The conclusion is that among three types of argumentation in the literature, which I call value judgments, information gathering, and construction, there is an unfortunate imbalance towards the first type. Too much has been written that adds neither facts nor ideas - there is only references to earlier research and weighing of points of view against each other. If there is only references to other scholars' works and no engagement with the arguments, it is difficult for others to reassess the results after new data has appeared. Too often, also, the conclusions are based on a pre-conceived theology, rather than a weighing of the factual support of the arguments.

    Abstract [en]

    Galatians 6:6 is commonly interpreted as instructing pupils to provide material support to their teachers, in return for the teaching received. It does not seem, however, that this is what the immediate context is about. To motivate this interpretation, one thus needs to show either that the words or expressions in 6:6 themselves, on grammatical, semantical or idiomatic grounds, give this meaning (that the verse can stand by itself), or else that it is probable from a cultural context that the words would be meant (and understood) in this way. This essay examines whether such arguments are viable and reaches a negative result. Thus the expression needs to be read in a way that is informed by the context, rather than diverging from it.

    Vårdrelationen mellan sjuksköterska och patient inom hemsjukvården: En litteraturstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: En god vårdrelation gynnar både patient och sjuksköterska. Patienten kan få en bättre upplevelse av vården och sjuksköterskan kan lättare individanpassa vården. En stor del av sjukvården bedrivs i hemmiljö och därför är det viktigt att belysa vårdrelationen i hemsjukvården.

    Syftet var att belysa vårdrelationen mellan sjuksköterska och patient inom hemsjukvården.

    Metoden som användes till litteraturstudien var Polit och Becks (2017) nio steg. Först skapades ett syfte och därefter valdes relevanta databaser och sökord ut. Artiklarna lästes, analyserades och granskades. Slutligen sammanställdes ett resultat som bestod av 10 kvalitativa artiklar med medelhög eller hög metodologisk kvalitet som svarade mot studiens syfte.

    Resultat: I resultatet framkom det att patienter uppskattade personliga vårdrelationer och att sjuksköterskor försökte uppnå en kombination mellan personlig och professionell vårdrelation. Patienter uppskattade delaktighet, tillit, kontinuitet och ett gott bemötande av sjuksköterskan i vårdrelationen. Resultatet utgjordes av 2 huvudteman: uppfattningar av vårdrelationen och komponenter i vårdrelationen samt sex underteman: personlig vårdrelation och professionell vårdrelation, trygghet och tillit, personliga egenskaper hos sjuksköterskan, delaktighet i vårdrelationen, samt närvaro och tid.

    Slutsats: I resultatet framkom att patienter och sjuksköterskor kunde se vårdrelationen som personlig, professionell eller bådadera. Patienter ansåg att sjuksköterskans personlighet, tillit, kontinuitet, respekt och delaktighet var viktiga faktorer i vårdrelationen.

    Abstract [sv]

    HIV är en av de största epidemierna i världen och i Sverige lever ca 5300 personer med HIV idag. HIV är en långvarig sjukdom där behandlingen består av bromsmediciner. Över hela världen är HIV förknippat med fördomar. Att drabbas av HIV innebär stora påfrestningar och omvälvningar i livet. Många upplever en känsla av skam, stigma och diskriminering vilket kan leda till ett lidande. Vårdpersonal behöver kunskap om HIV-sjukdomen och hur den upplevs av personer. Det kan hjälpa vårdpersonalen i vården av och i mötet med HIV-smittade personer. Syftet är att beskriva personers upplevelser av att få diagnosen HIV och hur det är att leva med sjukdomen. Uppsatsen är en litteraturstudie baserat på vårdvetenskapliga artiklar med kvalitativ inriktning. En litteratursökning i vårdvetenskapliga databaser gjordes vilket resulterade i tio artiklar som kvalitetsgranskades och analyserades. Likheter och skillnader i studiernas resultat identifierades och utmynnade i två huvudteman och åtta subteman. Upplevelser i samband med diagnos beskriver olika reaktioner i samband med att personerna får sin diagnos och känslan av att vara annorlunda. Att leva sitt liv med HIV beskriver hur personerna lever vidare, betydelsen av omgivningens stöd och upplevelser av möten i vården. Det mest framträdande i resultatet är livsförändring, stigmatisering, andlighet och upplevelser av möten i vården, vilka tas upp i diskussionen. Där betonas också vikten av att vårdpersonalen individanpassar vården, utgår ifrån ett livsvärldsperspektiv och att han/hon bemöter individen med respekt och värdighet.

    Abstract

    This paper is based on interviews, a literature study and seminars. It describes the

    situation in Halland when it comes to multi-story housing built in timber. From 1874

    to 1994, Sweden had a regulation that prohibited construction of timber houses with

    more than two stories as a result of big city fires. After the regulation was revoked,

    people started to build multi-story houses in timber again. Compared to the rest of

    the country there was not that many built in Halland. Construction entrepreneurs

    here possess the right competence and it is close to the raw material. Even though

    that, there are only five multi-story houses built in the county.

    Result from this study shows that the main problem of implementing multi-story

    housing built in timber is biases and lack of knowledge. Many of the players in the

    construction industry do not base their decisions on fact when it comes to choose

    timber or not. This in combination with a lack of information regarding financial

    issues and unfavorable regulations has resulted in a slow development of the

    implementation of multi-story houses. The reasons behind this are discussed in the

    paper and some possibilities of change are presented.

    Characterization of suspended particulate matter from freshwater: validation of a field filtration technique2004Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    A field filtration method for the concentration and separation of suspended particulate matter (SPM) from freshwater systems and the subsequent determination of major, minor, trace and ultra trace elements (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, Hf, K, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, S, Sb, Sc, Si, Sn, Sr, Ta, Th, Ti, Tl, U, V, W, Zn and Zr) is validated with respect to detection limits, precision, and bias. The validation comprises the whole procedure including filtration, sample digestion and instrumental analysis. The method includes two digestion procedures (microwave acid digestion and alkali fusion) in combination with inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma quadrupole mass spectrometry (ICP-QMS). Total concentrations of these 38 trace and major elements have been determined in suspended particulate matter (SPM) from lake and river water with low levels of suspended solids (<2 mg l-1 DW), and a wide range of element concentrations. The precision of the method including filtration, digestion and instrumental determination ranges between 8 and 18% RSD for most elements on a dry weight basis. Higher recovery after acid digestion is found for some elements, probably because of volatilization or retention losses in the fusion procedure. Other elements show higher recovery after fusion, which is explained by more efficient decomposition of mineral phases relative to the non-total acid digestion. Non-detectable concentrations of some elements are reported due to small differences between blank filter levels and the amounts of elements present on the filters after sampling. The calculated sums of main inorganic components, expressed as oxides, ranges between 94.0 and 98.0% ash weight. The method limits of detection range between 0.7 ng and 100 µg, as estimated from the blank filter samples. These detection limits are 3-1000 times higher compared to the corresponding instrumental limits of detection. The accuracy and bias of the overall analytical procedure was assessed from replicate analysis of certified reference materials. A better knowledge of the mechanisms of filter clogging in sampling of suspended matter is important in order to extend the applicability of the method. For the sample types investigated in this study, the amount of inorganic material in the suspended particulate matter (SPM) seems to be the most important factor controlling the maximum volume of filterable water, and Fe is presumable the most important clogging regulating parameter in the group of elements included in the inorganic matter. A critical evaluation of the instrumental capabilities of the ICP- QMS instrumentation in comparison with the sensitive double focusing sector field plasma mass spectrometry technique (ICP-SFMS) is also included. It was found that a modified microwave acid digestion procedure in combination with ICP-SFMS could replace ICP-AES determinations and fusion digestions for most of the investigated elements. Guidelines and limitations for this powerful and relatively simple and less time consuming procedure, covering most elements in one single determination, are discussed.
