This thesis is based on study of archive material and it focuses on the Grey Sisters Congregation of the Third Order of St.Francis, its history and places of activity since its foundation in 1856 until today. The introductory chapters describe the context of the period, which triggered formation of this as well as many other women's congregations in the second half of the 19th century, and congregations as such. The following chapters are specifically about the Grey Sisters. At first it chronologically presents history of the Congregation. Next chapter is about the former motherhouse in Bartolomejska Street and the current motherhouse in Lomnice u Vodnan. Further on the thesis describes the history and work of the sisters in filial houses, which they let built in the 1930's, and in the nursing school which they founded in Hradec Kralove. In the last chapter the life of the congregation itself is captured. The appendix contains pictures, graphs and a map describing the places of activity of the sisters.

Plack i arteria carotis kan ha olika utseende beroende på innehåll och morfologi. Det kan vara lågekogena eller högekogena plack. De lågekogena placken är mest problematiska eftersom de består av lipider och inflammationsceller som ger en mjuk konsistens och kan spricka och ledda till embolisering med stroke och kardiovaskulära incidenter som följd. För mätning av plack-ekogenicitet används i forskningssyfte ett GSM-värde, grey scale median som mäts med en ultraljudapparat med GSM-inställning. Ju lägre GSM-värde desto mer lågekogen är placken. Syftet med denna studie är att jämföra två GSM-värde för samma plack, den ena mätt med ultraljudstandardinställning och den andra mätt med GSM-inställningen för att avgöra om det blir en bra överensstämmelse mellan värdena. Om så är fallet innebär detta att plack-ekogenicitet kan avgöras i framtiden med mätning av GSM-värde med en ultraljudsapparat med standardinställning i forskningssyfte. Resultatet visade att det fanns en god överensstämmelse mellan en stor del av GSM-värdena, men det fanns en del värde där det blev en signifikant skillnad som gjorde att studien inte var tillräcklig övertygande för förväntade utfallet. / Plaque in the carotid artery can have different appearances depending on the content and morphology. It can be echolucent or more-echogenic plaques. The echolucent plaques are most problematic because they consist of lipids and inflammatory cells that give a soft consistency and can crack and lead to embolization with stroke and cardiovascular incidents as a result. For measuring plaque echogenicity for research purposes, a GSM value, gray scale median is used and is measured with an ultrasound device with a GSM setting. The lower the GSM value, the lower echolucent is the plaque. The purpose of this study is to compare two GSM values for the same plaque, one measured with the ultrasonic standard setting and the other measured with the GSM setting to determine if there is a good agreement between the values. If this is the case, this means that plaque echogenicity can be determined in the future by measuring GSM value with an ultrasound device with a standard setting for research purpose. The results showed that there was a good agreement between a large part of the GSM values, but there were some values where there was a significant difference which made the study not sufficiently convincing for the expected outcome.

This master´s thesis deals with management of water and their possibilities. First part contains description about possibilities of saving drinking water and their the most effective saving. Next part consists study of technological link for grey water cleaning and calculation of saving water with rate of return.

There is an ongoing discussion on grey zone deterrence and how states should deal with grey zone situations. Most studies are based around Russian actions in Crimea and Chinas actions in the East and South China Sea. The objective of this paper is to create a better understanding of the grey zone deterrence and the handling of grey zone situations by the Swedish navy. The method for achieving this is a text analysis of Swedish strategic, operative, and tactical doctrines. The result of the analysis shows that there is a discussion of grey zone deterrence on the operative level in the Swedish armed forces, where the Swedish navy can assist the police, coast guard, customs et.al. There is only a limited and implicit discussion on the tactical level specifically for naval units.  The conclusion of this paper is that the Swedish navy can work with other governmental departments to handle grey zone situations, however the Swedish navy is limited in the ability to handle grey zone situations independently.

With the advancements made in the field of data science, smart IoT devices are be-coming increasingly common. Consequently, this creates an increased number of targets for hackers to potentially exploit. This is a study about ethically hacking a robot vacuum, the Roborock S7, and evaluating the security of the target system. The DREAD and Stride threat models are used in order to find potential exploits. These exploits are then tested on the vacuum. Four tests were done on the system: scan-ning, denial-of-service attack, man-in-the-middle sniffing and man-in-the-middle tampering. The study found that the vacuum is relatively secure against web threats with weaknesses found surrounding its handling of its own network and lack of re-sistance to denial-of-service attacks on the DHCP protocol. / Med de framsteg som sker inom datavetenskap och teknologi blir IoT-enheter allt vanligare i hemmen. Detta medför en ökad mängd enheter med potentiella sårbar-heter som hackare kan utnyttja. Denna rapport handlar om att etiskt hacka en ro-botdammsugare av modell Roborock S7 och utvärdera dess säkerhet mot internet-hot. DREAD och STRIDE används som hotmodeller för att hitta sårbarheter. Sår-barheterna testas sedan på dammsugaren. Fyra tester utfördes på system: scanning, denial-of-service-attack, man-in-the-middle-avlyssning och man-in-the-middle-av-lyssning med manipulering. Rapporten hittade att dammsugaren är resonabelt säker mot internethot men med svagheter i hur enheten hanterar sitt egna nätverk samt ett bristande motstånd mot en denial-of-service-attack genom DHCP-protokollet.

Thesis (BEd)--Stellenbosch University, 1939. / INLEIDING: Die onderwys in Suid-Afrika het baie langsaam vooruitgegaan. Die Engelse Goeweneurs aan die Kaap was oor die algemeen onbekwaam en was buitendien so besig met politieke aangeleenthede dat hulle nouliks aandag kon gee a an die opvoeding. Daarom is dit dadelik opvallend wanneer ons 'n Goewaneur kry wat ook vir die geestelike belange van die bevolking 'n ope oog gehad het. So 'n Goeweneur was Sir George Grey, 'n man wat besonder bevoeg was en wat in alle rigtings baie vir Suid-Afrika gedoen het.

<p>The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.</p><p>The designed fault detection system showed to work well for the available data. It is, however, recommended that the performance of the system should be evaluated using more data. Another model based on data sampled once every minute for at least a year has to be developed before the system can be fully evaluated. The results shown were:</p><p>• The fault detection system can discover fast and slow changes in bearing temperature.</p><p>• No false alarms were given for measuring faults and sensor faults of the types used in this thesis. If a measuring fault occurs for too long there will be an alarm.</p><p>The fault detection algorithm was also implemented in Delphi to be used in a working system over the Internet where for example trends and alarms will be presented.</p> / <p>Syftet med examensarbetet var att utveckla ett automatiskt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner. De ingående parametrarna förutom bärlagertemperaturen var kylvattentemperaturen och kylvattenflödet. En enkel statisk modell baserad på data samplat en gång per minut togs fram för att estimera bärlagertemperaturen. Därefter utvecklades en detektor för att upptäcka avvikelser i bärlagertemperaturen baserad på CUSUM-algoritmen. På grund av en för liten mängd data var den framtagna modellen alltför osäker för att kunna implementeras i ett fungerande system.</p><p>Det framtagna feldetekteringssystemet visade sig fungera bra för de data som fanns tillgängliga. Det är däremot rekommenderat att utvärdera systemets prestanda med längre dataserier. En ytterligare modell baserad på minutdata över ett år måste tas fram innan systemet kan fungera på riktigt. De resultat som erhölls var:</p><p>• Feldetekteringssystemet klarar av att upptäcka abrupta och långsamma avvikelser av bärlagertemperaturen.</p><p>• Inga falsklarm ges då det är enstaka mätfel eller givarfel av sådan typ som tagits upp i arbetet. Pågår ett mätfel alltför länge ges dock ett larm.</p><p>Feldetekteringsalgoritmen implementerades även i Delphi för att kunna användas i ett fungerande system över Internet där t.ex. trendkurvor och larmsignaler skall kunna presenteras.</p>

<p>I Australien är vattenresurserna begränsade. För lantbrukare är tillgängligheten på vatten mycket viktig. På grund av det torra klimatet kan inte de Australiensiska bönderna förlita sig på nederbörden. Bevattningssystemen är därför en viktig del i jordbrukningsindustrin.</p><p>Bevattningsområdet i Coleambally ligger i södra New South Wales nära gränsen till staten Victoria. Bevattningsnätet i Coleambally förser ofta bevattningskanalerna med för mycket vatten för att vara säker på att lantbrukarna får den mängd vatten de behöver. På grund av denna tillförsel av överskottvatten går stor mängd av vatten förlorad. Design av ett bättre reglersystem skulle kunna minska den stora förlusten av vatten.</p><p>En matematisk modell beskrivande dynamiken av bevattningssystemet är ett bra redskap vid en design av ett bättre reglersystem. Syftet med det här projektet var att genom systemidentifiering bygga en matematisk modell av bevattningssystemet. Modellen syftade till att beskriva vattennivån i en sträcka av bevattningskanalerna, sträckan i kanalen skulle ha två olika typer av luckor, en typ där vattnet strömmar över luckan och en annan typ där vattnet strömmar under luckan. En modell byggdes genom att parametrar från en vald modellstruktur estimerades från experimentella data. Data samlades under ett experiment som utfördes på en bevattningskanal i Coleambally.</p><p>Resultatet från systemidentifieringen blev en första ordningens output error grey box modell. Modellen visar goda resultat vid validering och bör kunna användas vid design av ett bättre reglersystem. Modellen visar så god överensstämmelse med valideringsdata att den även kan användas för olika fall av simulering.</p> / <p>Water resources in Australia are limited. For a farmer the access to water is crucial and due to the dry climate the farmers in Australia can not rely on precipitation. Irrigation is therefore a very important part of the farming industry.</p><p>The Coleambally Irrigation Area is situated in the southern parts of New South Wales close to the border of Victoria. The Irrigation Network often supplies the irrigation channels with too much water to be sure that the demand of water is satisfied. Due to this over supply a great amount of water gets wasted. Design of a bettercontrol system would be able to reduce the water wastage.</p><p>A mathematical model describing the dynamics of the irrigation system can be used as a tool for the control system design. The aim of this project was to build a mathematical model with the system identification approach. The model should be able to describe the downstream water level of a single pool of an irrigation channel which has both undershot and overshot gates. A model was built by estimating unknown parameters of a chosen model structure from a set of experimental data. The data was collected from an experiment performed on the real irrigation system in Coleambally.</p><p>The result of the system identification was a first order output error grey box model. The model performs well on validation data and may therefore be used for design of a more efficient control system. The model gave such good results that it additionally may be used for various simulation purposes.</p>

This study focused on the investigation of the impact of household cleaning and personal care products on the quality of grey water and the assessment and optimisation of grey water treatment by a novel constructed wetland design. The prototype wetland design which comprised three-stage cascading beds (0.27 m 2 by 0.20 m deep) with sand media, (d10: 1.0 mm and d90: 4.0 mm) was tested for treatment performance to meet non-potable reuse standards in three versions, unplanted open beds, unplanted covered beds, and planted beds (comprising mixtures of Iris pseudacorus, Iris chrysographes, Carex elata Aurea and Mentha aquatica). The prototypes were benchmarked against a standard single-pass wetland (6 m 2 by 0.7 m) planted with Phragmites australis. Performance was measured in terms of removal of conventional water quality determinant parameters, as well as Total coliforms and E coli, and surfactants. Microbial dynamics were also monitored during the study by looking at variations in microbial compositions with time for the different wetlands. All the wetland versions effectively removed more than 98 % turbidity and organics meeting the most stringent reuse wastewater reuse standards of < 2.0 NTU and < 10 mg BOD5/L respectively. The influent grey water had low BOD:COD ratio ranging from 0.27 – 0.45, which is indicative of low biodegradability. The comparison of the cascade wetland performances showed the following: open beds > planted = covered, with the open beds version meeting reuse standards virtually throughout the monitoring period, despite recurrence of schmutsdecke in the top bed. All wetland technologies supported viable populations of microorganisms. Only phospholipid fatty acids (PLFAs) of lower carbon chain length (< C20) had concentrations greater than 1 mol %, in all the wetlands beds, confirming that the majority of the PLFAs in the media were from contribution of microbial organisms and not plant organic matter. Characterisation of microbial organisms was carried out to understand the constructed wetlands functioning and thus the treatment processes. The household products showed nutrient deficiency signifying low treatability. Product branding did not show correlation with any water quality parameters. In terms of toxicity, laundry and cleaning products were more inhibiting to soil microorganisms than were personal care products.
