The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.

The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.

In this master?s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi?s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead.

I detta projekt undersöker vi om man kan bygga en maskinaktivitetssensor medhjälp av en enkretsdator som genom en accelerometer mäter en maskinsvibrationer. Sensorn skall generera en statussignal. Accelerometern ger enmätbar signal baserad på maskinens vibrationer. Enkretsdatorn används för attsampla, transformera och analysera signalen och generera statusinformation.Med LabView kan vi spara, studera och analysera olika signaler och olikatransformer. Vi studerar maskinvibrationer i LabView och beslutar att 5 kHzsampling räcker för att fånga intressanta vibrationer.

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

Denna uppsats syfte är att analysera hur musikartister använder sig av YouTube som marknadsföringsverktyg, samt vilken betydelse YouTube har för dessa artisters marknadsföring. En kvalitativ och induktiv metod har tillämpats, medan ett antal intervjuer samt en innehållsanalys genomförts som grund till det empiriska materialet. Detta för att få en inblick i musikbranschens syn på ämnet, samt även ge en objektiv bild av hur plattformen används som marknadsföringsverktyg. Slutligen menade studien att ge artister och andra arbetande inom musikbranschen, en bild av hur användandet av denna marknadsföringskanal kan förbättras för att skapa en mer effektiv marknadsföring.  Den teoretiska referensramen har utgått från tidigare teorier kring YouTubes betydelse, roller och potential inom musikartisters marknadsföring. Teorier kring YouTubes möjliggörande för artister att upptäckas av A&R personer eller nya fans, YouTubes påverkan på musikvideons roll som marknadsföringsmedel, samt teorier kring plattformens påverkan på maktbalansen inom branschen har legat som grund.

This study aims to give an account of five teachers? views and understandings of second language (L2) learners? previous knowledge, as well as, their linguistic and cultural backgrounds. This is carried out by the means of qualitative interviews, where the sampling consists of five primary school teachers at various schools. The findings are presented and analyzed using a thematic analysis. Furthermore, the study indicates that teachers in general have a positive attitude to learning more about their L2 learners? prior knowledge and backgrounds, both for the pupils, as well as, their own sake.

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely. When radiocaesium decays to a stable end product ionizing radiation is emitted, which can cause cancer in humans that has been exposed to a high radiation dose. Radiocaesium behaves like potassium and is easily taken up into biological systems.

The most common method for identifying merchandise in the commerce is by barcodes. Symbian OS is an advanced operating system aimed at cell phones and the most commonly used in smart phones. Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

The aim of the study was to examine if the benthos in a restored portion of a small lowland stream south of Linkoping differed from two non restored reference areas two years after restoration. The reference areas were one stretch downstream and one upstream stretches of the restored stream. The benthic invertebrates were collected using standardized kick sampling. In order to classify the communities and estimate any differences, three different indices were exercised. In addition rank-abundance curves and checklists were used to get a picture of species composition.

Med utgångspunkt i de stora mängder kontanter som hanteras i flera instanser på Gekåsvarje dag valdes uppsatsens ämne.

De största kostnadsbesparingarnaskulle uppnås genom att vissa moment hos kassapersonal, på kassakontoretoch för den kassaansvarige försvinner.

Laser scanning is a method of surveying that has evolved rapidly in recentyears. The technique is based on a laser scanner set up, which can document a structureusing pulsed laser beams. Each time the laser hits a surface it is partly reflectedback to the scanner that stores the point. By using strategically placed targets, storedpoints from different scans can be merged into a point cloud. A point cloud is avisualization of the scanned object with a very high accuracy.
