Augmented Reality is one of the hottest trends in mobile media, yet there is a substantial lack of user studies within this field of research. The purpose of this study is to evaluate the value of mobile augmented reality as a vehicle for information delivery on the basis of a usability and design analysis. Using a multi-­dimensional qualitative method, this study examines the impressions of users and designers regarding mobile augmented reality, along with a heuristic evaluation of select mobile applications. This analysis finds that (1) users believe mobile augmented reality offers great promise as a medium for visual communication, and (2) it’s current execution is limited by technical restraints, design flaws and a lack of compelling content. It is concluded that mobile augmented reality will one day revolutionize how consumers engage geographical and time-basedinformation. Yet, like all new technologies, mobile augmented reality needs time to mature in order to address these limitations. Finally, based on the findings of this study, this thesis offers suggested guidelines for future developments in this medium. / Department of Telecommunications

The aim is to find out how teachers apply the knowledge they get from mathematics pilots in preschool and from mathematics developer in the municipality, as well as how they work further towards the children with mathematics. The study is based on qualitative interviews with two teachers, one mathematic pilot and one mathematic developer. I used the semi-structured interview questions. The results show that teachers believe that mathematics pilots will inspire the teachers in their work with mathematics in preschool. One of the teachers who were interviewed said: “Mathematics pilots should be those that have the strongest glasses and coming up with new ideas and they push the rest of the teachers in their work with mathematics in relation to children in preschool”. The teachers use the correct terms for mathematical concepts with the children. They also stressed how important it is to point out to the kids that it is mathematics that they are doing. The conclusion of the study is that the teachers agree that it is their approach towards the children that is important and how they can lead the children’s interest of mathematics forward. To get into the mathematics of everyday life is something that teachers feel is important. The teachers all agree that math is everywhere in daily life and does not always has to be a planned activity. / Syftet är att ta reda på hur pedagogerna omsätter kunskapen från matematikpiloterna i förskolan och från matematikutvecklaren i kommunen samt hur pedagogerna arbetar vidare gentemot barnen med matematik. Studien bygger på kvalitativa intervjuer med två pedagoger, en matematikpilot och en matematikutvecklare. Jag använde mig av halvstrukturerade intervjufrågor. Av resultaten framgår att pedagogerna anser att matematikpiloterna ska inspirera pedagogerna i deras arbete med matematik i förskolan. En av pedagogerna som intervjuades sa: ”Matematikpiloterna ska vara de som har de starkare glasögonen på sig och som kommer med nya idéer och pushar på de övriga pedagogerna i deras arbete med matematik gentemot barnen i förskolan”. Pedagogerna använder de rätta benämningarna för de matematiska begreppen till barnen. De betonar också hur viktigt det är att poängtera för barnen att det är matematik som de håller på med. Slutsatsen av studien är att pedagogerna är ense om att det är deras förhållningssätt till barnen som är viktig och hur de kan leda barnens intresse framåt för matematik. Att få in matematik i vardagen var något som pedagogerna ansåg viktigt. Att matematik finns överallt i vardagen och inte alltid behöver vara en planerad aktivitet, var pedagogerna överrens om.

Many of the materials used in dentistry are potentially harmful to the environment if their disposal is not performed correctly. Because of this, it is essential to raise the awareness of dentists about the recommended management and disposal, with a view to mitigating, if not annulling, the harmful effects on the environment and the population. Inadequate disposal of dental waste results in pollution of the soil and water, with immeasurable consequences. In view of the enormous risk posed by the inadequate disposal of dental waste, it is necessary to determine which measures should be taken with a view to minimizing such risks as well as which bodies are competent to set guidelines and regulate the subject. Primordial is the awareness of the dentist, who is responsible for handling the compounds directly and discarding their waste. Equally important are regulation and oversight, which can be performed concurrently by different spheres of government. At federal level, Anvisa has legal competence to deal with the matter, including penalties for inappropriate conduct. However, given the shortage of personnel, federal supervision is not always carried out satisfactorily, which is why a greater participation of municipal administrations is fundamental in this process. The present study consisted of a survey carried out with 84 dentists in the city of Guaratinguetá-SP, whose main objective was to verify the destination that was being given to dental developers and dental fixatives, and, in the alternative, also to be aware of the ecological awareness of the participants. At the end of the research, it was identified that the great majority of dental surgeons promoted the disposal of waste in an incorrect manner, by discarding the sewage network (73.81%) and the environment (8.33%). It was also verified that 82.14% of the participants did not have in their academic formation any discipline that covered the discard theme of dental developers and fixators and 92,86% never attended a lecture or congress that dealt with the theme. Regarding the chemical composition of developers and fixatives, 78.31% of interviewees had no such knowledge. It is concluded that only a small number of professionals proceed correctly regarding the disposal of chemical residues, showing timely inclusion of content in the curriculum of the Dentistry courses. / O exercício da Odontologia visa garantir higidez e a plena saúde bucal, entretanto, essa nobre atividade implica na geração de resíduos, os quais devem ser devidamente tratados para que sejam minimizados os impactos negativos sobre o meio ambiente e a sociedade. Muitos dos materiais utilizados na Odontologia são potencialmente danosos ao meio ambiente, caso seu descarte não seja realizado da forma correta. Em virtude disto, mostra-se essencial a conscientização dos cirurgiões-dentistas acerca do manejo e descarte recomendado, com vistas a amenizar, senão anular, os efeitos nocivos ao meio ambiente e à população. O descarte inadequado dos resíduos odontológicos acarreta poluição do solo e das águas, tendo consequências imensuráveis. Diante do enorme risco ocasionado pelo descarte inadequado dos resíduos odontológicos, faz-se necessário apurar quais condutas devem ser tomadas com vistas a minimizar tais riscos bem como quais os órgãos competentes para fixar diretrizes e regulamentar o assunto. Primordial é a consciência do dentista, que é o responsável por manusear diretamente os compostos e descartar seus resíduos. Igualmente importantes são a regulamentação e a fiscalização, as quais podem ser desempenhadas, concorrentemente, pelas diferentes esferas de governo. A nível federal, a Anvisa detém competência legal para tratar do assunto, havendo inclusive penalidades para condutas inadequadas. Entretanto, dada a carência de pessoal, a fiscalização federal nem sempre é realizada a contento, motivo pelo qual uma maior participação das administrações municipais mostra-se fundamental nesse processo. O presente trabalho consistiu em pesquisa realizada com 84 cirurgiões-dentistas do município de Guaratinguetá-SP, cujo objetivo principal foi verificar a destinação que estava sendo dada aos resíduos de reveladores e fixadores odontológicos e, subsidiariamente, também tomar conhecimento da consciência ecológica dos participantes. Ao término da pesquisa, identificou-se que a grande maioria dos cirurgiões-dentistas promovia a destinação de resíduos de maneira incorreta, mediante descarte na rede de esgoto (73,81%) e no meio ambiente (8,33%). Verificou-se também que 82,14% dos participantes não tiveram em sua formação acadêmica nenhuma disciplina que abrangesse o tema descarte de reveladores e fixadores odontológicos e 92,86% jamais presenciaram palestra ou congresso que tratasse do tema. No tocante à composição química de reveladores e fixadores, 78,31% dos entrevistados não detinham tal conhecimento. Conclui-se que apenas pequena parcela dos profissionais procede corretamente quanto ao descarte dos resíduos químicos, mostrando oportuna a inclusão de conteúdo na grade curricular dos cursos de Odontologia.

Most property development firms who invest in property will need to raise some extra financial support. Unforeseen or unexpected expenses can arise at any point in time during the development process. Calculated decisions should be taken with regards to the financial circumstances for any property development project. Decisions should be taken not only for the present but for the future as well. It is therefore important to understand the market and the current economic conditions before applying for capital to fund a property development project. There several types of finance available to fund property development, these include long term borrowing, short term borrowing, construction loans property development investment trust, second mortgages. There is risk to all of the aforementioned finance available.

Behovet av beslutsstödsystem ökar ständigt bland företagen världen över. För att ett beslutsstödsystem skall vara användbart och generera en nytta till ett företag, så finns det krav på att den information som visualiseras skall uppnå en viss datakvalitet. Således är syftet med detta arbete att undersöka vilka problem som uppstår vid utveckling av dashboards i strävan efter att uppnå en hög datakvalitet. I strävan efter att identifiera vilka problem och svårigheter som uppstår vid utveckling av dashboards för beslutsstöd så utfördes intervjuer med sex olika utvecklare av dashboards från olika företag i Sverige. Fokus under dessa intervjuer fanns på åtta olika aspekter som tillsammans genererar god datakvalitet. Denna studie har visat att samtliga utvecklare var överens om att datakvalitet är en mycket viktig aspekt när det kommer till dashboards och beslutsstödsystem och det framkom en variation av problem som kan uppstå i strävan efter att uppnå detta. Den här studien ger en god insyn i de problem som existerar inom detta område idag. / The need for decision support systems is constantly increasing among companies worldwide as well as the need for it to be useful and generate a benefit to a company. There is also a requirement that the information being visualized reaches a certain data quality. Thus, the aim of this research is to investigate the issues that arise during the development of dashboards sincerely with the interest of achieving high data quality. Since the aim of this study is to identify the issues and difficulties that arise during the development of dashboards for decision support, six interviews were conducted with different dashboard developers from various Swedish companies. During the interviews the focus was being put on eight different aspects that together generate good data quality The most relevant discovery made during this study was that the developers agreed on the fact that data quality is a highly relevant aspect when it comes to dashboards and decision support systems. Furthermore, there also emerged a variety of problems that arise with the interest of achieving high data quality. This study gives an insight to the issues that exist in the field today.

There is an estimated 16 million housing units shortfall in Nigeria and the government cannot meet the housing needs of Nigerians because of budgetary constraints and other competing needs. It is important to note that the leaders have failed on numerous occasions to tackle the key challenges associated with a lack of infrastructure development. The emphasis has been placed on the individual homeowners fulfilling all their own requirements. The aim of this research is to develop a framework that will aid sustainable housing delivery in Lagos one of the most challenged areas of Nigeria. A clearer picture of the housing environment in Lagos was documented based on critical literature reviews, analysis of the reasons why there is a deficiency in housing and its infrastructure delivery. The aim of the researcher was following the identification of the challenges to draw up a framework that would assist the relevant stakeholders namely the householders, developers and government in overcoming these and delivering further sustainable housing. The research was completed using a mixed method including qualitative and quantitative means of acquiring necessary information in the form of a detailed literature review followed by a questionnaire survey of 500 household respondents. A total of 496 sets of data were collected through the questionnaire survey and analysed using SPSS, Excel and selected statistical methods. Validation of the framework was done using focus group discussions with stakeholders. Interviews with key housing and government personnel were also held including an analysis of 5 case studies. The key findings are that 1) the market economy approach along with flexible, efficient economic instruments are key factors in enabling the construction industry to positively respond to sustainable development in terms of resource efficiencies and environmental protection in a developing economy like Nigeria. 2) The social and political barriers cannot be overcome without a meeting of wills amongst the stakeholders. 3) There needs to be transparency and the desire to achieve the objective so the monitors will be effective to counteract dissatisfied individuals that will come out of the bureaucratic woodwork. 4) There needs to be an urban redesign driven by stakeholders keen to see government policy align with sustainable housing objectives. Key recommendations from this research are that: 1) The government should partner with the private sector to provide enough homes for Nigerians. 2) The government should henceforth concentrate in outlining good policy framework for the sector providing much needed infrastructural and financial support that will encourage sustainability and systematic development of housing in the country. The framework developed in this research is envisaged to be contributory in road mapping the way and identifying key attributes and strategy for delivering sustainable housing in Lagos, Nigeria.

One of the latest tools in the strive troughwards a fast and secure Web is called WebAssembly. It is a low-level, assembly-like language that can run in the browser alongside JavaScript. WebAssembly is designed to load fast and aims to execute at near-native speed. Being a compilation target for system languages like C, C++, and Rust, WebAssembly is not very accessible from a Web developer perspective. This project explores ways to generate WebAssembly directly from JavaScript code, in order to lower the learning curve, and allow for a more widespread adoption of WebAssembly. This has resulted in a utility tool called Esmbly, which can turn simple JavaScript programs into WebAssembly binaries by collecting and utilizing type information from various flavours of statically typed JavaScript.
