Web technologies are becoming increasingly useful with new features and the gap to native apps is narrowing. Recently, IndexedDB was added to the web standard to provide large scale storage solutions directly in the browser. Is it performant enough to be used with a spatial database? In this study, such a system is developed for Foran Sverige AB and we learn that IndexedDB indeed can be used for this purpose. Even storage demanding geospatial applications can be developed as a multi- platform system with a single codebase, all while broadening the possible audience reach by avoiding an app installation process.

Android has been steadily gaining popularity ever since its launch in 2008. One of the major factors for this is the easy availability of a large variety of apps. They range from simple apps such as calculator apps to apps which can help people maintain their schedules and thus man-age many aspects of their lives. In addition, a lot of free apps are available to the user thanks to the power of in-app purchases and advertisements. However, these also raise many security concerns. Apps are privy to a lot of private information regarding the user, such as his contacts, location, etc. It is essential to ascertain that apps do not leak such information to untrustworthy entities. In order to solve this problem, there have been many static and dynamic analyses which aim to track private data accessed or generated by the app to its destination. Such analyses are commonly known as Information Flow analyses. Dynamic analysis techniques, such as TaintDroid, tracks private information and alerts the user when it is accessed by speci c API calls. However, they do not track the path taken by the information, which can be useful in debugging and validation scenarios. The first key contribution of this thesis is a model to perform dynamic information ow analysis, inspired by FlowDroid and TaintDroid, which can retain path information of sensitive data in an efficient manner. The model instruments the app and uses path-edges to track the information flows during a dynamic run. We describe the data structure and transfer functions used, and the reasons for its design based on the challenges posed by the Android programming model and efficiency requirements. The second key contribution is the capability to trace the path taken by the sensitive information based on the information obtained during the analysis, as well as the capability to compliment static analyses such as FlowDroid with the output of this analysis. The tests conducted on the implemented model using DroidBench and GeekBench 3 show the precision and soundness of the analysis, and a performance overhead of 25% while real-world apps show negligible lag. All leaks seen in DroidBench where successfully tracked and were verified to be true positives. We tested the model on 10 real-world apps where we find on average about 16.4% of the total path-edges found by FlowDroid.

A sub-bacia hidrográfica do Rio Una Mirim (SBHRUM) associada às outras sub-bacias formam a bacia hidrográfica do Rio Una. Cortada pelas rodovias BR 101 que liga Presidente Tancredo Neves a BR 324 e pela BA 452 que liga Valença a BR 101, a bacia hidrográfica do Rio Una Mirim pertence aos municípios de Valença e Laje, situados respectivamente no Recôncavo baiano (Costa do Dendê – região turística) e na mesorregião Centro-Sul ambos no estado da Bahia. O presente estudo teve como objetivo diagnosticar os principais impactos ambientais (desmatamento, queimadas, ausência da cobertura vegetal nas APPs, erosão, lixiviação, assoreamento dos rios, uso de produtos químicos, dentre outros) identificados na sub-bacia hidrográfica do Rio Una Mirim, a fim de fornecer contribuições para um planejamento voltado principalmente para preservação dos sistemas hídricos e, sobretudo, das APPs. Este estudo foi fundamentado principalmente no método Geossistêmico o qual visa uma análise integrada das variáveis (ambientais e sociais) que formam os sistemas, nesse caso, a subbacia hidrográfica do Rio Una Mirim. Outros elementos norteadores foram utilizados, como: Dados bibliográficos e cartográficos; obras de vários autores, como Geossistema reelaborado por Bertrand (1972), conceitos como: sistemas ambientais de Christofoletti (1999), sub-bacia hidrográfica de Santana (2000), impactos ambientais do CONAMA (1986), APPs do Código Florestal Brasileiro (1965), nascente relatado por Castro (1999), mata ciliar trabalhado por AB’Saber (2000), dentre outros; foram fontes basilares imprescindíveis para realização deste estudo. Para diagnosticar os impactos ambientais na Sub-bacia do Rio Una Mirim, foram desenvolvidas pesquisas de campo, trabalho de laboratório com o uso do ARCGIS. Os resultados obtidos com a pesquisa itinerante demonstraram que dentre as APPs visitadas em campo, (vertentes, matas ciliares e nascentes), algumas (em minoria) são parcialmente preservadas, estas, em função da menor proporção das atividades econômicas em seu entorno, porém, na maioria das APPs, foram identificados diversos impactos ambientais como desmatamento, queimadas, erosão, lixiviação, ausência das matas ciliares, assoreamento dos rios, uso de produtos químicos (adubos, fertilizantes...) dentre outros, ocasionados, sobretudo, pelo uso inadequado da terra voltado principalmente para a atividade agropecuária. / ABSTRACT This study aimed to identify the environmental issues arising in Permanent Protection Areas (PPAs) of the sub-basin of the River Una Mirim, in order to and cooperate with maintaining the balance of water systems, especially the springs, which are extremely important for the maintenance of a river basin or sub-basin. The sub-basin of the River Una Mirim (SBHRUM) associated with the other sub-basins form the basin of the River Una. Cut by the BR 101 highway linking President Tancredo Neves BR 324 and BA 452 connecting Valencia BR 101, the basin of the River Una Mirim belongs to the municipalities of Valencia and slab, located respectively in the Bahian Reconcavo (Dende Coast - region tourism) and in South-Central meso both in the state of Bahia. This study aimed to diagnose the main environmental impacts (deforestation, fires, lack of vegetation cover in APPs, erosion, leaching, silting of rivers, use of chemicals, among others) identified in the sub-basin of the River Una Mirim, to provide contributions to a plan primarily focused on preservation of water systems and, above all, the PPAs. This study was mainly based on Geossistêmico method which seeks an integrated analysis of the variables (environmental and social) that make up the systems, in which case the sub-basin of the River Una Mirim. Other guiding elements were used as bibliographic and cartographic data; works of various authors, as geosystem reworked by Bertrand (1972), concepts such as environmental systems Christofoletti (1999), sub-basin of Santana (2000), environmental impacts of CONAMA (1986), APPs the Brazilian Forest Code (1965 ), spring reported by Castro (1999), riparian worked for Ab'Sáber (2000), among others; were essential basic sources for this study. To diagnose the environmental impacts in the sub-basin of the River Una Mirim, were developed field research, laboratory work using the ARCGIS. The results obtained with the traveling survey showed that among the PPAs visited in the field, (slopes, riparian and springs forests), some (a minority) are partially preserved, these, due to the lower proportion of economic activities in its surroundings, however, most of the PPAs have been identified various environmental impacts such as deforestation, forest fires, erosion, leaching, absence of riparian forests, silting of rivers, use of chemicals (fertilizers, fertilizers ...) among others, caused mainly by inappropriate use land primarily designed for agricultural activity.

Capturing life as it is lived is an important goal in psychology, and diary methods are commonly used for this purpose. They capture events near the time of their occurrence and are less prone to retrospective biases associated with questionnaire, interview and survey methods. However, participants in diary studies must remember to carry the diary with them, and find it convenient to make entries in timely fashion. New approaches, replacing paper diaries with technology (e.g. personal digital assistants), can overcome forgetting to make entries and retrospective filling of data. However, until recently technology had its own problems (e.g. unreliability and cost of devices, the need for training, biases of technical competence, etc.). The research described in this dissertation arose from the anticipation that the rapid, worldwide growth of smartphone ownership would overcome many of these limitations since participant-owned smartphone diaries can eliminate associated costs and facilitate increased rates of compliance. Six diary studies were conducted on two transient cognitive phenomena. Initially, a smartphone app was developed and compared with a paper diary in the study of involuntary autobiographical memories. Although participants in the smartphone-diary condition demonstrated significantly better compliance than those in the paper-diary condition by reliably carrying their smartphones, and promptly completing diary entries in the app, they recorded significantly fewer events than paper diary users. To test that this unexpected finding was not specific to involuntary autobiographical memories, the method was tested with everyday memory failures, and the same unexpected finding was obtained. Further studies manipulated the length of diary-keeping period and demonstrated a diary entry rate reduction effect with longer diary keeping periods, an effect seen in both paper- and participant-owned smartphone-diaries. For involuntary autobiographical memories, the effect was demonstrated by comparing 1-day and 7-day diaries, and also by using a 30-40 minutelong digital audio recording method. With everyday memory failures, the effect was demonstrated by comparing 7-day and 28-day diaries. The audio recording method was used to capture involuntary autobiographical memories while driving. It was also used on a campus walk and compared with a 1-day paper diary within-subjects, finding a higher rate of recording in the shorter period, and consistency of memory counts across two modes of recording. This novel audio-recording method facilitated much more detailed analysis of involuntary memory cues and chaining and enabled the evaluation of potential instances of priming. Finally, a telephone and postal-based diary study of everyday memory failures demonstrated the feasibility of recruitment and measurement of participants remotely, which can be particularly useful with older adults. Taken together, the results of this research make a significant methodological contribution to research on transient everyday cognitive phenomena by showing that (1) care is needed when using participant-owned smartphone diaries, (2) paper diaries may be more reliable than currently given credit, and (3) diary-recording periods can be substantially reduced without compromising the quantity and the quality of data obtained. In addition, results increase our theoretical understanding of two specific phenomena studied in this dissertation: involuntary autobiographical memories and everyday memory failures. The findings indicate that involuntary memories are much more frequent than previously thought, may represent a stable characteristic of a person and, in addition to immediately present cues, can be elicited by internal memory chaining process and more distant priming of events and thoughts. Finally, the absence of age effects in the frequency and nature of recorded everyday memory failures, together with significant negative age effects in laboratory tests of memory and cognition, is a novel finding that has significant implications for research on cognitive ageing.

abstract: Mobile apps have improved human lifestyle in various aspects ranging from instant messaging to tele-health. In the current app development paradigm, apps are being developed individually and agnostic of each other. The goal of this thesis is to allow a new world where multiple apps communicate with each other to achieve synergistic benefits. To enable integration between apps, manual communication between developers is needed, which can be problematic on many levels. In order to promote app integration, a systematic approach towards data sharing between multiple apps is essential. However, current approaches to app integration require large code modifications to reap the benefits of shared data such as requiring developers to provide APIs or use large, invasive middlewares. In this thesis, a data sharing framework was developed providing a non-invasive interface between mobile apps for data sharing and integration. A separate app acts as a registry to allow apps to register database tables to be shared and query this information. Two health monitoring apps were developed to evaluate the sharing framework and different methods of data integration between apps to promote synergistic feedback. The health monitoring apps have shown non-invasive solutions can provide data sharing functionality without large code modifications and manual communication between developers. / Dissertation/Thesis / M.S.
