Using mobile devices to enhance undergraduate field research

Mobile devices can enhance undergraduate research projects and students’ research capabilities. The use of mobile devices such as tablet computers will not automatically make undergraduates better researchers, but their use should make investigations, writing, and publishing more effective and may even save students time. We have explored some of the possibilities of using “tablets” and “smartphones” to aid the research and inquiry process in geography and bioscience fieldwork. We provide two case studies as illustration of how students working in small research groups use mobile devices to gather and analyze primary data in field-based inquiry. Since April 2010, Apple’s iPad has changed the way people behave in the digital world and how they access their music, watch videos, or read their email much as the entrepreneurs Steve Jobs and Jonathan Ive intended. Now with “apps” and “the cloud” and the ubiquitous references to them appearing in the press and on TV, academics’ use of tablets is also having an impact on education and research. In our discussion we will refer to use of smartphones such as the iPhone, iPod, and Android devices under the term “tablet”. Android and Microsoft devices may not offer the same facilities as the iPad/iphone, but many app producers now provide versions for several operating systems. Smartphones are becoming more affordable and ubiquitous (Melhuish and Falloon 2010), but a recent study of undergraduate students (Woodcock et al. 2012, 1) found that many students who own smartphones are “largely unaware of their potential to support learning”. Importantly, however, students were found to be “interested in and open to the potential as they become familiar with the possibilities” (Woodcock et al. 2012). Smartphones and iPads could be better utilized than laptops when conducting research in the field because of their portability (Welsh and France 2012). It is imperative for faculty to provide their students with opportunities to discover and employ the potential uses of mobile devices in their learning. However, it is not only the convenience of the iPad or tablet devices or smartphones we wish to promote, but also a way of thinking and behaving digitally. We essentially suggest that making a tablet the center of research increases the connections between related research activities.

En utvärdering av Android och Iphone : För utveckling av webbtjänstunderstödda applikationer ämnade för intern distribution

Tack vare bättre och bättre förutsättningar för utveckling av mobila applikationer, samt utbredning av internetbaserade tjänster, presenteras här ett underlag inför val av mobil utvecklingsplattform. De undersökta plattformarna är Android och Iphone på grund av deras växande utbredning på smartphonemarknaden. Studien presenterar förutsättningar för att utveckla webbtjänst-understödda applikationer för intern distribuering. Ett visuellt tilltalande användargränssnitt är också i fokus för den typen av applikation studien riktar sig mot.Vi har kommit fram till att Android är lättare att lära sig om man kommer ifrån en Java- eller .Netmiljö samt lättare att distribuera. Iphone har däremot bättre stöd för att utveckla grafiskt tilltalande applikationer. Båda plattformarna har dock bristfälligt stöd för kommunikation via webbtjänster. Detta resultat uppnåddes genom litteraturstudier, samt en fallstudie där vi utvecklade applikationer med fokus på just webbtjänstkommunikation, intern distribuering samt ett tilltalande användargränssnitt.

IT­-Forensisk undersökning av flyktigt minne : På Linux och Android enheter

Att kunna gör en effektiv undersökning av det flyktiga minnet är något som blir viktigare ochviktigare i IT-forensiska utredningar. Dels under Linux och Windows baserade PC installationermen också för mobila enheter i form av Android och enheter baserade andra mobila opperativsy-stem.Android använder sig av en modifierad Linux-kärna var modifikationer är för att anpassa kärnantill de speciella krav som gäller för ett mobilt operativsystem. Dessa modifikationer innefattardels meddelandehantering mellan processer men även ändringar till hur internminnet hanteras ochövervakas.Då dessa två kärnor är så pass nära besläktade kan samma grundläggande principer användas föratt dumpa och undersöka minne. Dumpningen sker via en kärn-modul vilket i den här rapportenutgörs av en programvara vid namn LiME vilken kan hantera bägge kärnorna.Analys av minnet kräver att verktygen som används har en förståelse för minneslayouten i fråga.Beroende på vilken metod verktyget använder så kan det även behövas information om olika sym-boler. Verktyget som används i det här examensarbetet heter Volatility och klarar på papperet avatt extrahera all den information som behövs för att kunna göra en korrekt undersökning.Arbetet avsåg att vidareutveckla existerande metoder för analys av det flyktiga minnet på Linux-baserade maskiner (PC) och inbyggda system(Android). Problem uppstod då undersökning avflyktigt minne på Android och satta mål kunde inte uppnås fullt ut. Det visade sig att minnesanalysriktat emot PC-plattformen är både enklare och smidigare än vad det är mot Android.

Passive MVC och MVVM designmönster i Android : En jämförelse av kodkomplexitet mellan Passive MVC och MVVM

Det mobila operativsystemet Android är idag ett ganska dominerande operativsystem på den mobila marknaden dels på grund av sin öppenhet men också på grund av att tillgängligheten är stor i och med både billiga och dyra telefoner finns att tillgå. Men idag har Android inget fördefinierat designmönster vilket leder till att varje utvecklare får bestämma själv vad som ska användas, vilket ibland kan leda till onödigt komplex kod i applikationerna som sen blir svårtestad och svårhanterlig. Detta arbete ämnar jämföra två designmönster, Passive Model View Controller (PMVC) och Model View View-Model (MVVM), för att se vilket designmönster som blir minst komplext med hjälp av att räkna fram mätvärden med hjälp av Cyclomatic Complexity Number (CCN). Studien är gjord utifrån arbetssättet Design & Creation och ämnar bidra med: kunskap om vilket mönster man bör välja, samt om CCN kan peka ut vilka delar i en applikation som kommer att ta mer eller mindre lång tid att testa. Under studiens gång tog vi även fram skillnader på om man anväder sig av den så kallade Single Responsibilyt Principle (SRP) eller inte. Detta för att se om separerade vyer gör någon skillnad i applikationernas komplexitet. I slutändan så visar studien på att komplexiteten i små applikationer är väldigt likvärdig, men att man även på små applikationer kan se skillnad på hur komplex koden är men också att kodkomplexitet på metodnivå kan ge riktlinjer för testfall.

WISE-MUSE Mobile: aplicação móvel para monitorização ambiental de museus

Manter o património histórico, natural e artístico por muitos anos é de vital importância pois, sem este património, as gerações não poderiam ter conhecimento nem aprender todos os grandes acontecimentos que têm passado ao longo dos anos num determinado país. Para evitar que esse património se perca foi criado o projecto WISE-MUSE, que tem como objectivo principal a conservação preventiva de obras de arte através de monitorização ambiental, usando uma Rede de Sensores Sem Fios (RSSF) quer para recolher dados quer para transmiti-los. Apesar do projecto WISE-MUSE ser relevante para todos os museus, em geral, este foi aplicado ao caso específico do Museu da Baleia, localizado na Ilha da Madeira, em Portugal. Inicialmente, este projecto preocupava-se essencialmente com a monitorização ambiental das salas de exposição e das câmaras frigoríficas, usando uma rede de sensores sem fios distribuídos pelos espaços em questão. Uma RSSF permite obter dados essenciais à preservação das obras de arte num museu, de uma forma fácil e continua. Para tal, foram usados diferentes tipos de sensores para capturar parametros ambientais, tais como temperatura, humidade, luminosidade, CO e CO2. Um dos objectivos principais do projecto WISE-MUSE é conseguir visualizar as medições recebidas pelos sensores sem fios, de uma forma rápida e fiável, para que quando seja detectado algum problema, os responsáveis pelo museu possam actuar a tempo e resolver o problema sem danos maiores. Tendo em vista este objectivo, este trabalho de mestrado consistiu no desenvolvimento de uma aplicação móvel que permita a visualização e análise dos respectivos dados, em tempo real e independentemente do local onde os utilizadores se encontrem, enviando-lhes alertas caso seja detectado algum parâmetro com valores fora do normal. Esta aplicação foi implementada sobre o sistema operativo Android, por ser um dos mais usados por todo o mundo, assim como graças à sua facilidade de utilização quer por parte dos programadores quer por parte dos utilizadores finais.

Interface com o AEDROMO (Ambiente experimental e didático com robôs móveis) utilizando sistema Android

The AEDROMO (Experimental and Didactic Environment with Mobile Robots) is a versatile, user friendly and scalable environment that supports a wide range of experiments. In it there is an area that is similar to a desk where objects can interact with each other, including robots and other objects, and thus can perform numerous activities. In it's current state, AEDROMO has client computers that interact with the system through an interface, and thus realize the communication between the user and AEDROMO. This project offer support to create a new form of interface for AEDROMO and can therefore be used for devices running Android, the app developed in this project will serve as a basis for future work on this new interface

Desenvolvimento de aplicações Web com base em modelagem 3D: módulo Android

This project brings the development of an Android application which will allow users to access 3D models on web. The application developed allows Android devices to access web pages which have code that should use OPENGL to renderize. To demonstrate this functionality, an example web application was build, using technologies such as X3DOM and HTML5, which uses WebGL to get renderized. This web application gives to the user an environment of a virtual city, where he could surf by and interact with the objects. The Android application brings this immersion to the mobile world, also. The access and storage of data was developed a Webserver, which bring to the web application a simple API to give access to the database

Desenvolvimento de objeto de aprendizagem para dispositivos móveis explorando os sensores internos do sistema operacional Android

The traditional model of teaching little is modernized in recent decades. When in contact with this system, it is normal that the new-generation students feel unmo tivated in carrying out the proposed activities in the classroom. Considers Prensky (2001) these students, called Digital Natives, born with a modern way of thinking and learn and feel encouraged and motivated with activities that invite to interact. For this reason, it has been proposed the development of an object of learning in the form of application for Android tablets, exploring the internal sensors available in them, with the purpose of offering an interactive activity to students on the physical concepts involved in the process of photosynthesis in plants. For the construction, informational texts written in didactic language and easy to understand, illustrative images and animations were employed. In addition, we used the light sensor in the interactive activity on the process of photosynthesis so that the student could observe and understand how the environment is able to interfere with this process
