Föreliggande kandidatarbete har till syfte att undersöka fenomenet Webskrapning. Webbskrapnings-program (också kända som Web Wanderers, Crawlers, Spiders eller skrapare) är program som söker igenom webben automatiskt för att extrahera information från webbsidor. Ett exempel på web skrapning är när ett företag samlar in data om prissättningar på en vara eller en tjänst och sen använder informationen för att producera billigare erbjudanden. Detta ger företaget en fördel så att de kan fokusera mera på att marknadsföra sin sida/tjänster. Utöver detta så blir de utsatta företagens servrar också hårt belastade med trafik (skrapning) från ?icke kunder?. Efter att ha genomsökt både akademiska och allmänna källor via informationsinsamling, av denna information så dras slutsatsen att man inte fullt ut kan hindra skrapning av hemsidor. Detta på samma sätt som man inte fullt ut kan hindra någon IT-attack, det finns inga 100 % vattentäta system.

A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

This report presents a method for modelling a computer system from a security perspective. The questions that are going to be treated are:? What defines a secure system and how does the company relate to these factors?? What are the threats today based on hardware/software, human factors and company routines/policies?? What measures should be taken for the organisation to reach a higher level of security for their systems?? How do we develop a method for classification of security and what components should it contain?? What changes are reasonable and necessary with the respect to the company?s resources?The report has been done through interviews and analysis of existing systems on Fla?kt Woods AB. From analysis of material, the aspects judged relevant to the subject and to the company?s needs, have been compiled to a document.

This study was carried out at a company within the computer industry, a sector that is expanding and is facing scarcity of competent personnel. The purpose was to examine factors that are crucial for being an employer of choice. To get a profound picture of the employees' comprehension of their work situation, a qualitative method with semi-structured interviews with ten of the employees were conducted. To examine factors that are important for future employees a survey was created and handed out to fiftysix civil engineering students majoring in computer science. The results from the interviews showed that the organisation's culture was of great value to the employees.

Detta kandidatarbete utreder hur väl två operativsystems inbyggda brandväggar fungerar i symbios med en användares vanligaste tjänsteutnyttjande på Internet, samt att se hur likartade de är i sitt skydd från hot. De två operativsystemen som vi utgick ifrån var Microsoft Windows XP samt Red Hat Linux 8.0. Den hypotes vi arbetat kring lyder enligt följande: De två inbyggda brandväggarna är i stort likartade rörande skydd från hot på Internet och uppfyller användarnas tjänsteutnyttjande. De metoder vi använt, för att svara på vår frågeställning, har delats upp i ett funktionalitetstest och ett säkerhetstest. I funktionalitetstestet provades de vanligaste Internettjänsterna med den inbyggda brandväggen och ifall det uppstod några komplikationer eller ej. De två inbyggda brandväggarna genom gick i säkerhetstestet skannings- och svaghetskontroll via ett flertal verktyg. Genom resultatet kan vi konstatera att de inbyggda brandväggarna klarar av de vanligaste tjänsterna på Internet, men att en skillnad föreligger hos dem vad gäller exponeringen ut mot Internet.

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

Användningen av Internet och antalet nya tjänster ökar mer och mer. Internet är ett öppet system och för att Internet i högre utsträckning skall kunna användas även vid hantering av känslig information krävs bättre säkerhet. Syftet med denna rapport är att utifrån Karlskrona kommuns säkerhetspolicy samt medborgarnas åsikter om säkerhet, undersöka vilken eller vilka säkerhetslösningar som lämpar sig bäst vid den planerade 24-timmarsmyndigheten. I denna rapport undersöks vilken eller vilka av de alternativa medborgarcertifikat som myndigheter får använda sig av. Målet är att komma fram till en möjlig lösning för elektronisk identifiering inom den framtida, 24-timmarsmyndigheten inom Karlskrona kommun. För att genomföra denna utredning har vi använt oss av intervjuer, enkäter och litteraturstudier. Rapporten innehåller även bakgrundsfakta för att få en ökad förståelsen av innehållet.

Abstract This report is our bachelor thesis. Our work has taken place at a galvanising company in Sölvesborg. The company faced major changes, of which one was a computerisation process. The new system could involve changes in work practice and in specific tasks, affecting the workers. If the coming system was to support work, from the production personnel?s perspective, we felt a legitimate participation in the development and design of the future work practice, was a requirement that was not met. During our ethnographical studies we noted that conflicts arose between production and administrative -personnel.

The thesis analyzes two different approaches towards responsive web design, Mobile-first and Desktop-first. Responsive web design is a concept for websites whose design is customised based on the screen size. The analysis is performed by collecting views on the methods and also analyzing the usage of mobile and desktop internet to create a prototype of a responsive website where both methods are beeing used.The main difference between the methods is the foundation, where one is designed for mobile and the other for desktop. The thesis indicates that Mobilef-irst gives a better result for the mobile, which unlike the computer has poor performance, smaller screen and poor internet connection, therefore an advantage for the device that needs more focus to maintain a fast response. Desktop-first does not take this opportunity, but focus instead on the computer where the performance is better, which leads to a unnoticeable difference in response time.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

The education in Swedish schools today should be for all children. This means that even if a pupil has reading and writing disabilities the education should be in the classroom with the rest of the pupils. The education should include every one.The aim of my study was to investigate the education with pupils that have reading and writing disabilities. I wanted to get a deeper knowledge about working methods that are used for pupils with these problems.In my study I have used qualitative research methods. I have used group interviews and observational studies.

Dagens människa är ytterst beroende av webbtjänster och med tiden har det blivit fler och viktigare tjänster som startat upp på internet. Viktiga tjänster som internetbanker. Oftast är det bara ett användarnamn och ett lösenord som krävs för att bli autentiserad så man skulle kunna tro att användarna håller hårt i sina lösenord och att de väljer starka/unika lösenord. För många verkar det dock, enligt källor, vara ett besvär. Borde man ha associeringar för att lätt komma ihåg sitt lösenord eller är det för riskabelt? Det har visat att många tycker om att använda ord som förknippas med webbsidan.

The aim of this essay was to investigate how teachers in the preschool class work with literacy. How do they justify the methods used to develop children's literacy abilities? I also wanted to know to what extent teachers enable multimodal approaches within written language practices. My study considers the impact teachers' professional identity has on working methods in the preschool class. I hope this essay will help teachers reflect on their learning approach. I gathered information by interviewing three preschool teachers and one compulsory school teacher for the early years working in three different preschool classes in three different schools.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.
