Methodology for in-game certification in serious games

Serious games are starting to attain a higher role as tools for learning in various contexts, but in particular in areas such as education and training. Due to its characteristics, such as rules, behavior simulation and feedback to the player's actions, serious games provide a favorable learning environment where errors can occur without real life penalty and students get instant feedback from challenges. These challenges are in accordance with the intended objectives and will self-adapt and repeat according to the student’s difficulty level. Through motivating and engaging environments, which serve as base for problem solving and simulation of different situations and contexts, serious games have a great potential to aid players developing professional skills. But, how do we certify the acquired knowledge and skills? With this work we intend to propose a methodology to establish a relationship between the game mechanics of serious games and an array of competences for certification, evaluating the applicability of various aspects in the design and development of games such as the user interfaces and the gameplay, obtaining learning outcomes within the game itself. Through the definition of game mechanics combined with the necessary pedagogical elements, the game will ensure the certification. This paper will present a matrix of generic skills, based on the European Framework of Qualifications, and the definition of the game mechanics necessary for certification on tour guide training context. The certification matrix has as reference axes: skills, knowledge and competencies, which describe what the students should learn, understand and be able to do after they complete the learning process. The guides-interpreters welcome and accompany tourists on trips and visits to places of tourist interest and cultural heritage such as museums, palaces and national monuments, where they provide various information. Tour guide certification requirements include skills and specific knowledge about foreign languages and in the areas of History, Ethnology, Politics, Religion, Geography and Art of the territory where it is inserted. These skills are communication, interpersonal relationships, motivation, organization and management. This certification process aims to validate the skills to plan and conduct guided tours on the territory, demonstrate knowledge appropriate to the context and finally match a good group leader. After defining which competences are to be certified, the next step is to delineate the expected learning outcomes, as well as identify the game mechanics associated with it. The game mechanics, as methods invoked by agents for interaction with the game world, in combination with game elements/objects allows multiple paths through which to explore the game environment and its educational process. Mechanics as achievements, appointments, progression, reward schedules or status, describe how game can be designed to affect players in unprecedented ways. In order for the game to be able to certify tour guides, the design of the training game will incorporate a set of theoretical and practical tasks to acquire skills and knowledge of various transversal themes. For this end, patterns of skills and abilities in acquiring different knowledge will be identified.

Improvement of a filters method in a derivative free optimization

Constraints nonlinear optimization problems can be solved using penalty or barrier functions. This strategy, based on solving the problems without constraints obtained from the original problem, have shown to be e ective, particularly when used with direct search methods. An alternative to solve the previous problems is the lters method. The lters method introduced by Fletcher and Ley er in 2002, , has been widely used to solve problems of the type mentioned above. These methods use a strategy di erent from the barrier or penalty functions. The previous functions de ne a new one that combine the objective function and the constraints, while the lters method treat optimization problems as a bi-objective problems that minimize the objective function and a function that aggregates the constraints. Motivated by the work of Audet and Dennis in 2004, using lters method with derivative-free algorithms, the authors developed works where other direct search meth- ods were used, combining their potential with the lters method. More recently. In a new variant of these methods was presented, where it some alternative aggregation restrictions for the construction of lters were proposed. This paper presents a variant of the lters method, more robust than the previous ones, that has been implemented with a safeguard procedure where values of the function and constraints are interlinked and not treated completely independently.

Otimização do processo produtivo de extrusão de pisos na E06

O presente trabalho foi elaborado no âmbito da Dissertação Final de Mestrado do curso de Engenharia Mecânica – Gestão Industrial do Instituto Superior de Engenharia do Porto. Este foi realizado numa empresa da indústria de pneus, a Continental Mabor S.A.. Nos dias atuais, a indústria esta cada vez mais competitiva, os custos e os prazos da entrega são cada vez mais reduzidos e a qualidade cada vez mais exigente, assim sendo, é imprescindível uma constante melhoria do sistema produtivo. Este fato fez com que o presente trabalho tivesse como principal objetivo determinar o estado atual e delinear um plano de melhoria para um equipamento (Extrusora de pisos nº6), recentemente instalado na fábrica mas oriundo de outra fábrica do grupo, recorrendo para tal ao Lean Manufacturing e a ferramentas que lhe estão associadas. Inicialmente realizou-se uma análise e diagnóstico ao processo de extrusão de pisos na Extrusora nº6, com o intuito de avaliar todas as suas ineficiências e ainda formular um plano de melhorias para a ineficiência de maior impacto no sistema produtivo. Esta análise foi realizada em diferentes turnos e diferentes equipas de trabalho de forma a se obter uma amostra mais representativa da realidade global. Após esta análise verificou-se que as principais ineficiências eram Setup, conformidade do material, dimensões e encravamentos, entre outros. Sendo que os Setup provocam um tempo de paragem de 101 minutos por turno, escolheu-se esta perturbação como o foco do plano de melhorias a realizar posteriormente. De forma a reduzir os tempos de mudança (Setup), o autor no presente trabalho utilizou ferramentas Lean Manufacturing, principalmente o SMED. Conjuntamente com o SMED ainda foram utilizadas outras ferramentas Lean Manufacturing tais como: 5S, Gestão Visual, Problem Solving e Normalização do Método de Trabalho. Após a implementação de todas estas ferramentas obteve-se uma redução de tempos de mudança de 43% com 1 operador e 71% com 2 operadores, ou seja, reduziu-se de 40,5 minutos gastos por turno para a mudança de fieira para 23,13 min e 11,79 min respetivamente, o que corresponde a um ganho monetário anual de 63.621€ ou 105.045€, respetivamente. Com este trabalho conclui-se que a utilização de ferramentas Lean Manufacturing contribuem para a redução dos desperdícios do processo produtivo. Por isso, espera-se que este estudo seja aplicado na Extrusora nº6 e nas restantes Extrusoras de pisos existentes na fábrica, e num futuro próximo que se realize estudos semelhantes em máquinas com diferentes funções.

Belief Revision in Multi-Agent Systems

The ability to respond sensibly to changing and conflicting beliefs is an integral part of intelligent agency. To this end, we outline the design and implementation of a Distributed Assumption-based Truth Maintenance System (DATMS) appropriate for controlling cooperative problem solving in a dynamic real world multi-agent community. Our DATMS works on the principle of local coherence which means that different agents can have different perspectives on the same fact provided that these stances are appropriately justified. The belief revision algorithm is presented, the meta-level code needed to ensure that all system-wide queries can be uniquely answered is described, and the DATMS’ implementation in a general purpose multi-agent shell is discussed.

Provably Good Task Assignment for Two-Type Heterogeneous Multiprocessors Using Cutting Planes

Consider scheduling of real-time tasks on a multiprocessor where migration is forbidden. Specifically, consider the problem of determining a task-to-processor assignment for a given collection of implicit-deadline sporadic tasks upon a multiprocessor platform in which there are two distinct types of processors. For this problem, we propose a new algorithm, LPC (task assignment based on solving a Linear Program with Cutting planes). The algorithm offers the following guarantee: for a given task set and a platform, if there exists a feasible task-to-processor assignment, then LPC succeeds in finding such a feasible task-to-processor assignment as well but on a platform in which each processor is 1.5 × faster and has three additional processors. For systems with a large number of processors, LPC has a better approximation ratio than state-of-the-art algorithms. To the best of our knowledge, this is the first work that develops a provably good real-time task assignment algorithm using cutting planes.

CDIO and the European Project Semester: a match for capstone projects?

The CDIO Initiative is an open innovative educational framework for engineering graduation degrees set in the context of Conceiving – Designing – Implementing – Operating real-world systems and products, which is embraced by a network of worldwide universities, the CDIO collaborators. A CDIO compliant engineering degree programme typically includes a capstone module on the final semester. Its purpose is to expose students to problems of a greater dimension and complexity than those faced throughout the degree programme as well as to put them in contact with the so-called real world, in opposition to the academic world. However, even in the CDIO context, there are barriers that separate engineering capstone students from the real world context of an engineering professional: (i) limited interaction with experts from diverse scientific areas; (ii) reduced cultural and scientific diversity within the teams; and (iii) lack of a project supportive framework to foster the complementary technical and non-technical skills required in an engineering professional. To address these shortcomings, we propose the adoption of the European Project Semester (EPS) framework, a one semester student centred international capstone programme offered by a group of European engineering schools (the EPS Providers) as part of their student exchange programme portfolio. The EPS package is organised around a central module – the EPS project – and a set of complementary supportive modules. Project proposals refer to open multidisciplinary real world problems and supervision becomes coaching. The students are organised in teams, grouping individuals from diverse academic backgrounds and nationalities, and each team is fully responsible for conducting its project. EPS complies with the CDIO directives on Design-Implement experiences and provides an integrated framework for undertaking capstone projects, which is focussed on multicultural and multidisciplinary teamwork, problem-solving, communication, creativity, leadership, entrepreneurship, ethical reasoning and global contextual analysis. As a result, we recommend the adoption of the EPS within CDIO capstone modules for the benefit of engineering students.

Development of Biomimetic Robots in the EPS Engineering Programme Capstone Project

This paper proposes the development of biologically inspired robots as the capstone project of the European Project Semester (EPS) framework. EPS is a one semester student centred international programme offered by a group of European engineering schools (EPS Providers) as part of their student exchange programme portfolio. EPS is organized around a central module (the EPS project) and a set of complementary supportive modules. Project proposals refer to open multidisciplinary real world problems. Its purpose is to expose students to problems of a greater dimension and complexity than those faced throughout the degree programme as well as to put them in contact with the socalled real world, in opposition to the academic world. Students are organized in teams, grouping individuals from diverse academic backgrounds and nationalities, and each team is fully responsible for conducting its project. EPS provides an integrated framework for undertaking capstone projects, which is focused on multicultural and multidisciplinary teamwork, communication, problem-solving, creativity, leadership, entrepreneurship, ethical reasoning and global contextual analysis. The design and development of biologically inspired robots allows the students to fulfil the previously described requirements and objectives and, as a result, we recommend the adoption of these projects within the EPS project capstone module for the benefit of engineering students.

Audição harmónica: importância e estratégias para um desenvolvimento auditivo integral

O presente relatório insere-se no âmbito da unidade curricular de Prática de Ensino Supervisionada. É um trabalho individual de síntese e de reflexão fundamentada sobre o percurso realizado no estágio, e de investigação com vista à resolução de problemas e conhecimento da realidade das práticas educativas do sistema de ensino especializado de música. Deste modo, é definido o quadro contextual sobre a evolução deste sistema de ensino e as complexidades que o têm caraterizado, o desenvolvimento curricular, particularmente o lugar que a disciplina de Formação Musical ocupa no currículo, e o Conservatório de Música de Paredes. Sobre o percurso formativo desempenhado nesta instituição educativa e sobre os dados recolhidos da observação naturalista não participante das aulas de duas turmas do ensino articulado, é elaborada uma reflexão crítica fundamentada, relativamente a todos os processos didáticos e pedagógicos. Complementarmente é apresentado um projeto de investigação qualitativa realizado no âmbito da unidade curricular de Seminário de Investigação em ensino de Música, tendo em vista a contribuição para uma prática pedagógica mais enriquecida, informada e fundamentada. O objeto de estudo está relacionado com a área disciplinar de Formação Musical, sob o tema Audição Harmónica: importância e estratégias para um desenvolvimento auditivo integral. Os objetivos do projeto visam verificar: i) quais os recursos utilizados e as estratégias e metodologias de ensino praticadas nas aulas de Formação Musical para o desenvolvimento da audição harmónica; ii) quais os objetivos e conteúdos contemplados nos programas da mesma disciplina; iii) que atividades são sugeridas em alguns manuais de Formação Musical. Os dados obtidos permitiram verificar que, apesar da importância atribuída à audição harmónica na formação de músicos, esta competência representa uma das maiores dificuldades dos alunos e, no âmbito da Formação Musical, há pouca diversidade de vivências, experiências musicais e outras atividades contextualizadas musicalmente.
