Användning av molntjänster har gjort forensiska undersökningar mer komplicerade. Däremot finns det goda förutsättningar om molnleverantörerna skapar tjänster för att få ut all information. Det skulle göra det enklare och mer tillförlitligt. Informationen som ska tas ut från molntjänsterna är svår att få ut på ett korrekt sätt. Undersökningen görs inte på en skrivskyddad kopia, utan i en miljö som riskerar att förändras. Det är då möjligt att ändringar görs under tiden datan hämtas ut, vilket inte alltid syns. Det går heller inte att jämföra skillnaderna genom att ta hashsummor på filerna som görs vid forensiska undersökningar av datorer. Därför är det viktigt att dokumentera hur informationen har tagits ut, helst genom att filma datorskärmen under tiden informationen tas ut. Informationen finns sparad på flera platser då molntjänsterna Office 365 och Google Apps används, både i molnet och på den eller de datorer som har använts för att ansluta till molntjänsten. Webbläsare sparar mycket information om vad som har gjorts. Därför är det viktigt att det går att ta reda på vilka datorer som har använts för att ansluta sig till molntjänsten, vilket idag inte möjligt. Om det är möjligt att undersöka de datorer som använts kan bevis som inte finns kvar i molnet hittas. Det bästa ur forensisk synvinkel skulle vara om leverantörerna av molntjänster erbjöd en tjänst som hämtar ut all data som rör en användare, inklusive alla relevanta loggar. Då skulle det ske på ett mycket säkrare sätt, då det inte skulle gå att ändra informationen under tiden den hämtas ut. / The usage of cloud services has made forensics investigations more complicated. But there are good foundations if the cloud service providers would create services to retrieve all the information. It would make the process easier and more reliable. The most difficult part to do correctly is to download the information from the cloud services. The investigation is done in a volatile environment and not on a secured copy. It is possible that changes are made during the time the data is retrieved, which is not always visible. It is not possible to compare the differences in files with hash values, in the same way as forensic investigations of computers. That is why it is very important to document how the information is retrieved, preferably by recording the computer screen during the time the information is retrieved. The information is saved on multiple locations when the cloud services Office 365 and Google Apps are used, both in the cloud and on the computer that is being used to access the cloud. The web browser saves a lot of information of what has been done. That is why it is important to find out which computer has been used to connect to the cloud service, which is not possible today. If it would be possible to examine all the computer that have been used, evidence that is no longer in the cloud could be found, The best through a forensic angle would be if the cloud service providers offered to retrieve all data which involves a user, including all relevant logs. Then it would be possible to retrieve the data with a secure method, because it would not be possible to change the information during the retrieval.

The primary purpose of this study is to determine in which technology we have to develop an application depending on the features that we would like to include, in order to deliver the best value for a good price to the customers. Consequently, in this research we have described the capabilities, performance and limitations that we have found while using the different technologies. The empirical part of this study was conducted in the first semester of 2014/2015 at the Linnaeus University in Växjö (Sweden), supported by Softwerk Company. In conclusion, the thesis shows that the user experience with native apps is always better than using the web-based technologies, especially using maps, although the time and effort spent to develop them is higher. Cross-platform solutions can be very useful for simple apps, and also if the developer does not have a lot of time to develop them. The problem with this last kind of applications is that the performance is less than the native ones.

On the journey of learning a language we are exposed to countless words that are easily forgotten and subsequently difficult to find again. This study investigates how to design a personal data management system that enables its users to efficiently organize, find and input the words and phrases that they encounter on their journey. Using DSRM, an artifact was iteratively developed and tested in usability tests and interviews by a total of 10 participants. The feedback from the respondents indicates a strong demand for this type of app and also uncovered design knowledge in this new context. The contribution of this study is a set of 14 design principles for making data management in language learning apps more user-friendly and efficient.

The purpose of this study was to understand boaters’ adoption and usage of smartphones and mobile apps as well as to obtain their opinion on potential features of a targeted mobile app being developed as part of a broader interdisciplinary Florida Sea Grant outreach project. Data were gathered from an online survey of a sample of 164 boaters from the surrounding Central Florida area. In contrast with previous empirical mobile app studies, many respondents reported using mobile apps for information-seeking versus escape gratifications. Further more than half of the respondents’ age sixty-five and over indicated using smartphones and mobile apps. These findings reflected recent national trend data showing shifting gratifications and an increase in technology use among older American adults. In regards to the planned mobile app, the study’s respondents had favorable reactions to its potential features and indicated an above average intent toward downloading the app

Com estes dois pilares, esta pesquisa objetiva compreender a concepção de uma metrópole comunicacional softwarizada que emerge do uso de aplicativos para dispositivos móveis de comunicação (os smartphones). Essas mídias móveis tornaram-se parte essencial deste trabalho por proporcionarem mobilidade ao usuário que circula pelos espaços físicos, promovendo uma maior interação com o contexto territorial e ocasionando novas dinâmicas de comunicação e convívio. Dados referenciados no interior desta tese nos levam a crer que em pouco tempo praticamente todos os aparelhos de telefonia móvel serão smartphones, fato este que reconfigurará de vez as práticas urbanas estabelecidas. Além das características comunicacionais que carrega, a metrópole observada é também interpretada como um ambiente criativo, projetual, audiovisual e softwarizado, que recebe interferências de outras áreas do conhecimento, como o design. Neste contexto, um conjunto de aplicativos para dispositivos móveis (os apps) que exploram questões urbanas surge como um instrumento contemporâneo que conversa de diferentes formas com esta múltipla metrópole, desde a concepção de suas práticas até as mutações culturais que ocasionam. Para responder aos questionamentos desta pesquisa e identificar as transformações decorridas, fez-se uso do personagem flâneur, de Walter Benjamin, como recurso metodológico que ocasionou a definição e análise de 15 fragmentos contextuais extraídos da metrópole observada nos apps e em suas imagens. O cruzamento destes fragmentos destacou particularidades e dinâmicas que atualizaram o entendimento de Metrópole Comunicacional, interpretando-a como uma combinação entre suas ruas, avenidas e as dinâmicas ocasionadas pelos apps sobre elas, tal como acontece entre selfies e paisagens urbanas, entre check-ins e benefícios ganhos, entre a smarphonização que se instaura e a falta de sinal Wi-Fi predominante, uma mistura entre perder-se e não perder-se jamais, entre a cultura digital e os processos midiáticos, entre modelos, hábitos e experiências vividas, entre criatividade e projeto, entre vozes, meios e mensagens, entre compartilhamentos e dispositivos, ou ainda, uma composição entre os próprios aplicativos móveis e a metrópole comunicacional com que interagem. / This dissertation has as its starting point the concept of Comunicational Metropolis proposed by Massimo Canevacci, establishing a connection with the research of Lev Manovich, which explains an increasing influence of software in our society. Thus, taking these two pillars as a foundation, this research aims to understand the concept of a communicational metropolis that is emerging from the use of applications for mobile communication devices (smartphones). Mobile media has become a key part of this work since they provide mobility to the user who moves around physical spaces, promoting greater interaction with the local context and causing new communication and social dynamics. Data referenced within this thesis indicate that in a short period of time, almost all mobile handsets will be smartphones and will reconfigure once and for all the existing social practices. However, the metropolis observed in this study overcomes the communicational framework proposed, since it is also a creative, projectual, audiovisual and softwarized environment. In this context, a set of mobile applications exploring urban issues arise as a contemporary tool. In different ways, this tool dialogues with the multiple metropolis, from the design practices that daily occur in it, to the cultural transformations generated by this tool. In order to answer the research questions and to identify the changes that happened, Walter Benjamin’s character flâneur was used as a methodological resource that gave rise to the construction and analysis of 15 fragments extracted from a digital communicational metropolis observed through popular apps and its images. The intersection of these fragments highlighted peculiarities and dynamics that updated the understanding of a Communicational Metropolis, structuring it as a combination of its streets, avenues and dynamics caused by the apps. A combination of selfies and urban landscapes; check-ins and earned benefits; the established ‘smarphonization’ and the lack of predominant WiFi signal; getting lost and not ever getting lost; digital culture and media processes; models, habits and experiences; creativity and design; voices, media and messages; shares and devices; that is, a composition of mobile applications themselves and the communicational metropolis which they interact with.

I detta examensarbete har ett IT-verktyg utvecklats som stödjer kvalitetsutvärderingen av en ingenjörsutbildning. I dagsläget innehåller kvalitetsutvärderingen flera moment som kräver manuell hantering av data. IT-verktyget automatiserar ett flertal av momenten och detta effektiviserar arbetet genom tidsbesparing och minskad risk för misstag. Examensarbetets syfte är således att underlätta genomförandet av kvalitetsutvärderingen genom automatisering. Metoden för arbetet är en fallstudie vid en av Sveriges ingenjörsutbildningar. Metodvalet ger möjlighet till verkliga tester och evidens för att kontrollera och påvisa att det utvecklade verktyget fungerar i enlighet med de behov som finns. Resultatet av detta examensarbete är ett IT-verktyg som stödjer, underlättar, förfinar och förtydligar kvalitetsutvärdering av ingenjörsutbildning på grundnivå. Verktyget är byggt med tjänster ur Google:s utbud, där användargränssnittet utgörs av produktivitetsapplikationerna Sheets och Forms. Skriptplattformen Apps Script tillför automatisering av repetitiva moment och möjliggör att applikationerna kan sammanlänkas med en databas i molntjänsten Cloud SQL. IT-verktyget bedöms även kunna fungera för andra typer av utbildningar som kvalitetsprövas mot lärandemål och examensmål. / In this thesis an information technology tool is developed to support quality evaluation of an engineering education. Presently the quality evaluation contains several steps that require data to be handled manually. The information technology tool automates several of the steps. This leads to increased work efficiency and reduces the risk of mistakes. The purpose of the thesis is therefor to facilitate the quality evaluation through automatization. The method chosen for development is a case study conducted at a Swedish engineering program. The choice of method makes it possible to conduct tests based on an actual education program to verify and show that the developed tool is functioning correctly according to existing needs. The result of this thesis is a working information technology tool that supports, refines and concretizes quality measurement of engineering education at a bachelor level. The tool is built using services provided by Google. The productivity apps Sheets and Forms are utilized as the user interface, and used in conjunction with the scripting platform Apps Script, the apps are connected with a cloud database in the Cloud SQL service. The tool is assumed to work for other types of educations that are quality checked using intended learning outcomes and examination objectives.

Mobile applications play an important role in the dissemination of computing and information resources. They are often used in domains such as mobile banking, e-commerce, and health monitoring. Cost-effective testing techniques in these domains are critical. This dissertation contributes novel techniques for automatic construction of mobile application test suites. In particular, this work provides solutions that focus on the prohibitively large number of possible event sequences that must be sampled in GUI-based mobile applications. This work makes three major contributions: (1) an automated GUI testing tool, Autodroid, that implements a novel online approach to automatic construction of Android application test suites (2) probabilistic and combinatorial-based algorithms that systematically sample the input space of Android applications to generate test suites with GUI/context events and (3) empirical studies to evaluate the cost-effectiveness of our techniques on real-world Android applications. Our experiments show that our techniques achieve better code coverage and event coverage compared to random test generation. We demonstrate that our techniques are useful for automatic construction of Android application test suites in the absence of source code and preexisting abstract models of an Application Under Test (AUT). The insights derived from our empirical studies provide guidance to researchers and practitioners involved in the development of automated GUI testing tools for Android applications.
