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. .

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

För att minnas långa lösenord är det inte ovanligt att användare rekommenderas att skapa en mening som sedan sätts ihop till ett långt lösenord, en lösenordsfras.Informationsteoretiskt sett är dock ett språk väldigt begränsat och förutsägbart, varför enligt Shannons definition av informationsteori en språkriktig lösenordsfras bör vara relativt lätt att knäcka.Detta arbete riktar in sig på knäckning av språkriktiga lösenordsfraser, dels i syfte att avgöra i vilken grad det är tillrådligt att basera en lösenordspolicy på lösenordsfraser för skydd av data, dels för att allmänt tillgängliga effektiva metoder idag saknas för att knäcka så långa lösenord.Inom arbetet genererades fraser för vidare användning av tillgängliga knäckningsprogram, och språket i fraserna modelleras med hjälp av en Markov-process. I denna process byggs fraserna upp genom att det används antal observerade förekomster av följder av bokstäver eller ord i en källtext, så kallade n-gram, för att avgöra möjliga/troliga nästkommande bokstav/ord i fraserna.Arbetet visar att genom att skapa modeller över språket kan språkriktiga lösenordsfraser knäckas på ett praktiskt användbart sätt jämfört med uttömmande sökning..

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.

The expectations of a successful outcome are great during childbirth. The overall objective of prenatal care and birth care is that midwives contribute in creating the most positive experience of pregnancy, child birth and infancy as possible. During the past 30 years there has been a significant increase in sectiofrequency both in Sweden and the rest of the Western world. More parents feel an overall insecurity when it comes to child labour. The purpose of this study was to describe how midwives experience the work of creating a sense of security and good nursing when meeting the expectant parents.

Syftet med denna studie har varit att beskriva, analysera och förstå hur elever som är nya på en skola kan uppleva trygghet i både fysisk och social miljö, samt bevara och/eller bygga upp sin inre trygghet. Inför studien granskades nationella riktlinjer och råd och genom litteraturstudier i ämnena trygghet, lärande, grupprocesser och människans grundläggande behov, lades en förförståelse för ämnet. En hermeneutisk ansats var ledgivande under hela studien, i synnerhet under det analyserande och tolkande stadiet. Kvalitativa intervjuer genomfördes med tre elever i blandade åldrar i åk 1-5. Det visade sig att eleverna hade behov av trygghet under den första tiden i en ny miljö och att de framförallt hittade den tryggheten i jämnåriga kompisar.

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.

In the curriculum for Swedish pre-school the focus is mainly on five concepts. These are care of the children, learning, influence, rearing and security. These concepts are to characterize the activities of the pre-school in Sweden.Back in time the focal point of pre-school activities for young children was mainly on security. The learning part became more prominent as the children grew older. When speaking to teachers and parents I do sense that some believe this is the case even nowadays.

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

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.
