Localization system for pedestrians based on sensor and information fusion

Nowadays there is an increase of location-aware mobile applications. However, these applications only retrieve location with a mobile device's GPS chip. This means that in indoor or in more dense environments these applications don't work properly. To provide location information everywhere a pedestrian Inertial Navigation System (INS) is typically used, but these systems can have a large estimation error since, in order to turn the system wearable, they use low-cost and low-power sensors. In this work a pedestrian INS is proposed, where force sensors were included to combine with the accelerometer data in order to have a better detection of the stance phase of the human gait cycle, which leads to improvements in location estimation. Besides sensor fusion an information fusion architecture is proposed, based on the information from GPS and several inertial units placed on the pedestrian body, that will be used to learn the pedestrian gait behavior to correct, in real-time, the inertial sensors errors, thus improving location estimation.

Design of a Compact Genetic Microstrip Antenna with improved performance

In this paper the design issues of compact genetic microstrip antennas for mobile applications has been investigated. The antennas designed using Genetic Algorithms (GA) have an arbitrary shape and occupies less area (compact) compared to the traditionally designed antenna for the same frequency but with poor performance. An attempt has been made to improve the performance of the genetic microstrip antenna by optimizing the ground plane (GP) to have a fish bone like structure. The genetic antenna with the GP optimized is even better compared to the traditional and the genetic antenna.

La revolución del internet ha llevado a muchos cambios. Con el paso del tiempo, dependemos menos de los papeles y más de los archivos digitales. Los niveles de información han incrementado exponencialmente y la interconectividad que han brindado servicios como redes sociales se encuentra en niveles jamás pensados hace media década. Sin embargo, el mercado laboral tradicional ha visto pocos cambios; a pesar de que han surgido numerosas ocupaciones y desaparecido puestos del mismo modo, la gran mayoría de personas se ven obligadas a buscar el sustento propio y de sus familias dedicándole una cantidad considerable de tiempo a su trabajo y dejando de lado muchos otros asuntos pertinentes al hogar, a los negocios e incluso asuntos personales. El sistema de adquisición de servicios se encuentra completamente estancado. En Colombia, según cifras de 2011 del Departamento Administrativo Nacional de Estadistica (DANE), existen más de 10 millones de viviendas y más de 500.000 establecimientos de comercio, que por lo menos una vez por año tienen un reparo para hacer, por esta razón, se genera una amplia demanda en la prestación de este tipo de servicios. Miles de personas continúan sin encontrar servicios específicos a sus necesidades en el momento adecuado, incluso cuando existe dinero destinado hacia los mismos, en gran parte debido a los esquemas tradicionales y la inhabilidad de conectar necesidades con servicios. Este emprendimiento busca cambiar ese esquema tradicional de las páginas amarillas, los clasificados y otras fuentes que se han quedado en el siglo XX como medio publicitario de trabajos realizados por independientes en temas relacionados con el hogar u oficina y abrir camino hacia una nueva forma de encontrar un apareamiento en tiempo real y enfocado en los consumidores, creando una sitio web y posteriormente aplicaciones móviles, en la que cada cliente puede comparar los precios estandarizados de cada servicio del hogar, pagar electrónicamente lo pactado y dejar calificaciones del servicio posteriormente; cambiando el estilo de negociación de modo más formal y bajo un esquema que logre acuerdos mutuamente beneficiales. En el corto plazo, se busca que las personas puedan considerar alternativas a los esquemas existentes para dar a satisfacer sus necesidades. En el mediano y largo plazo el objetivo del 4 proyecto es romper los paradigmas en los mismos que se han mantenido desde tanto tiempo y revolucionar su funcionamiento conforme a las herramientas existentes en la actualidad. El siguiente proyecto tiene como propuesta proveer una solución completa para los hogares y establecimientos comerciales en términos de adquisición de servicios prestados por personas independientes y con poca o nula regulación en el mercado actual. Es una propuesta que permite cambiar la logística y el modelo de negociación de mediante una herramienta virtual que adicionalmente brinde una respuesta más rápida y facilidad de uso.

Geotagging photographs in student fieldwork

This resource paper provides guidance for staff and students on the potential educational benefits, limitations and applications of geotagging photographs. It also offers practical advice for geotagging photographs in a range of fieldwork settings and reviews three free smartphone applications (apps) for geotagging photographs (Flickr, Evernote and Panoramio). Geotagged photographs have the potential to encourage post-fieldwork student reflection on a landscape. A short case study of first-year undergraduates who geotagged photographs as a method of data collection is outlined. This resource paper also briefly discusses the use of student-owned devices in fieldwork which may reduce pressure on departmental budgets.

Context relevant persuasive interaction and design: consideration of human factors influencing B2C persuasive interaction

The revolutions of electronic and mobile commerce have opened up unique opportunities for global marketing and business to consumer (B2C) persuasive interaction; with the aim of influencing user behavior. The success or failure of such persuasive interaction is impacted by cultural, social, and personal dimensions. Accordingly, failure to consider such dimensions risks the user forming a negative attitude towards retailer’s websites or mobile applications, which subsequently threatens customer behavior. A better understanding of human factors influencing the way people perceive B2C persuasive interaction is needed. This paper is introduces the concept of a context relevant persuasive interaction and proposes a guideline for designing relevant B2C persuasive interaction.

Smart-phone based electrocardiogram wavelet decomposition and neural network classification

This paper discusses ECG classification after parametrizing the ECG waveforms in the wavelet domain. The aim of the work is to develop an accurate classification algorithm that can be used to diagnose cardiac beat abnormalities detected using a mobile platform such as smart-phones. Continuous time recurrent neural network classifiers are considered for this task. Records from the European ST-T Database are decomposed in the wavelet domain using discrete wavelet transform (DWT) filter banks and the resulting DWT coefficients are filtered and used as inputs for training the neural network classifier. Advantages of the proposed methodology are the reduced memory requirement for the signals which is of relevance to mobile applications as well as an improvement in the ability of the neural network in its generalization ability due to the more parsimonious representation of the signal to its inputs.

Testverktyg för test av mobila applikationer : En jämförande fallstudie

Användandet av mobila applikationer har växt radikalt de senaste åren och de samverkar med många system. Därför ställs det högre krav på kvaliteten och att applikationen ska anpassas till många olika enheter, operativsystem samt plattformar. Detta gör att test av mobila applikationer blivit viktigare och större. Detta arbete har bedrivits som en jämförande fallstudie inom området test av mobila applikationer samt testverktyg. Syftet har varit att beskriva hur testning av mobila applikationer sker idag vilket gjorts genom litteraturstudier och intervjuer med IT-företag. Ett annat syfte har varit att utvärdera fyra testverktyg, deras för- och nackdelar samt hur de kan användas vid testning av mobila applikationer och jämföras mot manuell testning utan testverktyg. Detta har gjorts genom att skapa förstahandserfarenheter baserat på användandet av testverktygen. Under arbetet har vi utgått från mobila applikationer som vi fått tillgång till av Triona, som varit vår samarbetspartner.Idag finns många olika testverktyg som kan användas som stöd för testningen men få företag har implementerat något eftersom det kräver både tid och kompetens samt valet av testverktyg kan vara svårt. Testverktygen har olika för- och nackdelar vilket gör att de passar olika bra beroende på typ av projekt och applikation. Fördelar med att använda testverktyg är möjligheten att kunna automatisera, testa på flera enheter samtidigt samt få tillgång till enheter via molnet. Utmaningarna är att det kan vara svårt att installera och lära sig testverktyget samt att licenserna kan vara dyra. Det är därför viktigt att redan innan implementationen veta vilka tester och applikationer testverktygen ska användas till samt vem som ska använda det. Utifrån vår studie kan slutsatsen dras att inget testverktyg är helt komplett men de kan bidra med olika funktioner vilket effektiviserar delar av testningen av mobila applikationer.

Smartphone malware based on synchronisation vulnerabilities

Smartphones are mobile phones that offer processing power and features like personal computers (PC) with the aim of improving user productivity as they allow users to access and manipulate data over networks and Internet, through various mobile applications. However, with such anywhere and anytime functionality, new security threats and risks of sensitive and personal data are envisaged to evolve. With the emergence of open mobile platforms that enable mobile users to install applications on their own, it opens up new avenues for propagating malware among various mobile users very quickly. In particular, they become crossover targets of PC malware through the synchronization function between smartphones and computers. Literature lacks detailed analysis of smartphones malware and synchronization vulnerabilities. This paper addresses these gaps in literature, by first identifying the similarities and differences between smartphone malware and PC malware, and then by investigating how hackers exploit synchronization vulnerabilities to launch their attacks.

ipreps on ipads : exploring the visual/audio nexus of techno-literacy learners in an Australian classroom

This presentation reports on findings from a qualitative study on the use of iPads to support the literacy learning of a group of children who had just commenced their formal schooling in a regional Australian preparatory classroom. Specifically it looks at the affordances the iPad offered to enhance the oral-aural-visual communication of children not yet fluent in print based literacies. The children were interviewed about their techno-literacy learning and observed as they engaged with applications (apps). The researchers were able to video them as they demonstrated high levels of interest, energised learning and a range of independently acquired techno- literacy skills.
There is as yet little research on the use of portable personal computing devices such as the iPad in early years’ classrooms. The children in this study are shown as capable and articulate regarding their iPad use. Beyond the traditionally conceived struggle with passive print decoding when using iPads they become active creators of sophisticated multimodal artefacts that they consider worthy of acclaim, “I’m really proud of myself.” Findings from this study suggest the visual/listening nexus of popular apps potentially challenges print based literacy education approaches and existing paradigms of research and teaching/learning practice in Australian early years’ literacy education.

Remote monitoring system enabling cloud technology upon smart phones and inertial sensors for human kinematics

Stroke is a common neurological condition which is becoming increasingly common as the population ages. This entails healthcare monitoring systems suitable for home use, with remote access for medical professionals and emergency responders. The mobile phone is becoming the easy access tool for self-evaluation of health, but it is hindered by inherent problems including computational power and storage capacity. This research proposes a novel cloud based architecture of a biomedical system for a wearable motion kinematic analysis system which mitigates the above mentioned deficiencies of mobile devices. The system contains three subsystems: 1. Bio Kin WMS for measuring the acceleration and rotation of movement 2. Bio Kin Mobi for Mobile phone based data gathering and visualization 3. Bio Kin Cloud for data intensive computations and storage. The system is implemented as a web system and an android based mobile application. The web system communicates with the mobile application using an encrypted data structure containing sensor data and identifiable headings. The raw data, according to identifiable headings, is stored in the Amazon Relational Database Service which is automatically backed up daily. The system was deployed and tested in Amazon Web Services.
