Programming Principles: Collections and Iterators

In this session we look at how we can use collection objects like ArrayList as a more advanced type of array. We also introduce the idea of generics (forcing a collection to hold a particular type) and see how Java handles the autoboxing and unboxing of primitives. Finally we look at Iterators, a common design pattern for dealing with iteration over a collection.

Portabilitat d'aplicacions de PC a PDA mitjançant un cas d'estudi : ScummVM

L’objectiu del treball és estudiar la portabilitat dels programes que han estat originalment dissenyats per a un PC a un dispositiu mòbil, en concret a un PDA amb el sistema operatiu Palm OS. Per al nostre treball, hem escollit una aplicació com a cas d’estudi que ens permet donar solucions a les limitacions que presenta el dispositiu amb Palm OS. Aquesta aplicació s’anomena ScummVM, i es tracta d’una implementació de codi lliure del conegut motor de videojocs SCUMM, creat i utilitzat per LucasArts en les seves aventures gràfiques. Donarem possibles solucions a la problemàtica que genera el fet que la pantalla del dispositiu mòbil utilitzat tingui una resolució de 160x160 a l’hora de mostrar imatges i textos renderitzats per una resolució superior. També solucionarem el problema que representa el fet de no tenir ratolí, ni altres dispositius d’entrada i sortida tradicionals. La intenció és explicar també el procés que s’hauria de seguir per poder portar aplicacions de PC a Palm OS i les eines que s’utilitzarien. Tot això es farà sempre de la manera menys invasiva possible, és a dir, els canvis al codi font de l’aplicació original seran els mínims per garantir el correcte funcionament del programa en la nova plataforma

A Multi-agent Architecture with Distributed Coordination for an Autonomous Robot

Aquest treball proposa una nova arquitectura de control amb coordinació distribuïda per a un robot mòbil (ARMADiCo). La metodologia de coordinació distribuïda consisteix en dos passos: el primer determina quin és l'agent que guanya el recurs basat en el càlcul privat de la utilitat i el segon, com es fa el canvi del recurs per evitar comportaments abruptes del robot. Aquesta arquitectura ha estat concebuda per facilitar la introducció de nous components hardware i software, definint un patró de disseny d'agents que captura les característiques comunes dels agents. Aquest patró ha portat al desenvolupament d'una arquitectura modular dins l'agent que permet la separació dels diferents mètodes utilitzats per aconseguir els objectius, la col·laboració, la competició i la coordinació de recursos. ARMADiCo s'ha provat en un robot Pioneer 2DX de MobileRobots Inc.. S'han fet diversos experiments i els resultats han demostrat que s'han aconseguit les característiques proposades per l'arquitectura.

Real-time identification and modelling in pervasive mining

This paper introduces an architecture for identifying and modelling in real-time at a copper mine using new technologies as M2M and cloud computing with a server in the cloud and an Android client inside the mine. The proposed design brings up pervasive mining, a system with wider coverage, higher communication efficiency, better fault-tolerance, and anytime anywhere availability. This solution was designed for a plant inside the mine which cannot tolerate interruption and for which their identification in situ, in real time, is an essential part of the system to control aspects such as instability by adjusting their corresponding parameters without stopping the process.

The design and implementation of an active replication scheme for distributing services in a cluster of workstations

Replication is the key to providing high availability, fault tolerance, and enhanced performance in a cluster of workstations (COWs). However, building such a system remains as a difficult and challenging task, mainly due to the difficulty of maintaining data consistency among replicas and the lack of easy and efficient tools supporting the development procedure. In this paper we propose an active replication scheme in which data consistency can be maintained. Based on the active replication scheme, we present an object-oriented design pattern and a constructing tool to simplify the design and implementation of service replications in COWs.

Optimization-based formation of autonomous mobile robots

The formation of autonomous mobile robots to an arbitrary geometric pattern in a distributed fashion is a fundamental problem in formation control. This paper presents a new asynchronous, memoryless (oblivious) algorithm to the formation problem via distributed optimization techniques. The optimization minimizes an appropriately defined difference function between the current robot distribution and the target geometric pattern. The optimization processes are performed independently by individual robots in their local coordinate systems. A movement strategy derived from the results of the distributed optimizations guarantees that every movement makes the current robot configuration approaches the target geometric pattern until the final pattern is reached.

Sustaining Victorian certificate of applied learning (VCAL) educators

This paper draws on emerging data from in-progress analysis of interviews with 22 teachers/educators who teach the Victorian Certificate of Applied Learning (VCAL) in the settings of schools, Adult Community Education (ACE) and Technical and Further Education (TAFE). The development and implementation of VCAL occurred in 2002 as a response to Victorian government policy initiatives resulting from the Kirby (2000) Report. The VCAL is offered alongside the Victorian Certificate of Education (VCE), in years 11 and 12 of school, as another pathway into employment or further education and training. VCAL is also offered in the settings of TAFE and ACE. The VCAL curriculum uses applied learning as a pedagogical foundation to engage students in relevant, meaningful and authentic learning. In schools VCAL is delivered by qualified and registered teachers. In the TAFE and ACE sectors VCAL is taught by staff who are not necessarily teacher trained. Many pre-service teaching courses (including Certificate IV in Workplace Training and Assessment) do not include applied learning pedagogy in the curriculum. Since VCALʼs implementation there have been calls for greater consultation with, and support given to, VCAL teachers and organisations (Knipe, Ling, Bottrell and Keamy, 2003, p. 6; Harrison, 2006). Additionally VCAL teachers are frequently ill prepared professionally to manage a cohort which includes a high concentration of disengaged young people demonstrating challenging behaviours and attitudes (Pritchard & Anderson, 2006, p.1). Emerging data from the interviews with VCAL educators indicates these issues have not been addressed and many educators and teachers continue to feel unprepared and poorly supported. This is particularly significant in the light of a recent Victorian government announcement that, despite rising VCAL enrolments, VCAL coordination funding to schools is to be cut in 2012. (VALA, 2011, para. 4). To compensate for a lack of structured support and preparation, VCAL educators are frequently sustaining professional practice by their own agency in adapting already held life-skills and knowledge.

School practitioners’ perceptions of the pre-service teacher education practicum: a comparative study

The importance of strong school-university partnerships in bridging the so-called theory- practice gap in pre-service teacher education has been well established in the literature. The experiences of pre-service teachers during practicum have in particular been shown to be enhanced where there are strong links between the two educational sectors. This paper draws from research conducted in two diverse Australian pre-service teacher education programs to evaluate factors that are perceived to profoundly impact on the professional experiences of pre-service teachers during practicum. The particular focus of this paper is the beliefs and experiences of school practitioners and university staff members regarding the efficacy of the practicum in enabling students to enact theory in practice. A mixed methods approach was adopted for both studies, one of which was located in an urban university in Tasmania, the other in a regional university in Queensland. Findings generated from the comparative study of both programs revealed some differences but predominantly a number of similarities between the perceptions of the two samples of school practitioners and university staff members towards practicum. Three key findings are presented and discussed in this paper.

Findings from a pilot study into student retention beyond Year 10

This paper reports on early findings from a pilot study into student retention beyond Year 10. Located in rural, regional and disadvantaged communities in Tasmania, the research has implications at State, national and international levels. It is being funded by a nationally competitive Australian Research Council Linkage grant and the Tasmanian Department of Education across three years. The paper begins by providing a conceptual overview of the research, including the background to the study, and then reports on trends that have emerged during the initial phase of data collection. Preliminary findings resulting from pilot data analysis of responses to questionnaires by students in Years 5 and 9/10 are discussed. The paper concludes with a discussion about what these early findings suggest in regard to factors impacting on student retention.

Understanding the balance of experienced teachers' ICT learning

In the Information Age, ICT learning requires a balance between the concrete and experiential learning process and the abstract conceptualisation of Andragogy. Future Teacher Professional Development will need to understand the complexities of the concrete experience and the abstract conceptualisation of new knowledge. Professional Development will need to comprehend how experienced teachers as digital immigrants learn. It will further need to understand what abilities are essential for these experienced teachers and how they develop an awareness of their ICT learning. This paper will examine a study that was undertaken with a group of Post Registration Primary School Educators. These experienced teachers undertook the Post Registration or fourth year of their Bachelor of Education (Primary) course at an Australian Educational Institute. These experienced teachers with limited ICT exposure went through an ICT learning process over a period of one year. They finally acquired the ICT knowledge and skills, however within the time span of one year, theoretical pedagogy was absent or minimal.

How do Digital Immigrant Teachers (DITs) learn ICT for the information age?

This study reports about teacher learning and in particular, teachers who have extensive teaching experience but limited ICT knowledge and skills. The Digital Immigrant Teachers (DITs) grew up before digital technologies; they are not frequently confident or comfortable with ICT. Like all immigrants, they have to learn new and creative ways to enhance their survival in the third millennium, where the acceleration of knowledge has allowed communication and application of information to be rapidly disseminated. In order to fully participate in the technologically rich society DITs must actively engage in the construction of authentic and purposeful learning. This research came about as a result of the digital immigrants' struggles to construct and acquire the necessary knowledge and skills to teach in the Knowledge Economy and the Information Age. The experienced present day teachers, as digital immigrants are trying to teach digital natives (Prensky, 2001 & 2003). And in order to assist these teachers in their learning ICT struggle, it is imperative to understand the teacher learning process, and the learning style through which they acquire the knowledge and skills for this new milieu.
