A INVENÇÃO CONSISTE NUM DISPOSITIVO QUE PERMITE A AQUISIÇÃO E A ANÁLISE DE DADOSPARA DETERMINAÇÃO DOS COMPARTIMENTOS CORPORAIS GORDO E NÃO GORDO. A INVENÇÃOÉ UM LIPOCALIBRADOR, FIGURA 1 MODIFICADO DE FORMA A PERMITIR A MEDIÇÃO AUTOMÁTICAE A RECEPÇÃO DA INFORMAÇÃO, POR RÁDIO FREQUÊNCIA (9), PARA MEIOS INFORMÁTICOS (10)CORRENTES. O SISTEMA PERMITE A ANÁLISE DOS DADOS RECOLHIDOS E A DETERMINAÇÃOAUTOMÁTICA DA DENSIDADE E DA GORDURA CORPORAL ATRAVÉS DOS VÁRIOS MÉTODOS DEREFERÊNCIA. A MEDIÇÃO DAS PREGAS DE GORDURA CUTÂNEA COM O LIPOCALIBRADOR É REALIZADADO SEGUINTE MODO: AGARRANDO O EQUIPAMENTO PELO PUNHO (1) E PREMINDO A ALAVANCA (3)MANIPULAM-SE OS BRAÇOS (4A, 4B) EM TORNO DO SEU EIXO DE ROTAÇÃO (2), DE MODO A AFASTARAS MAXILAS (5A, 5B), DE ACORDO COM OS PROCEDIMENTOS CONVENCIONADOS NA LITERATURA.POSICIONANDO AS MAXILAS NA ZONA A MEDIR (PREGA CORPORAL), LIBERTA-SE A ALAVANCA (3). OAJUSTE DA PRESSÃO DAS MAXILAS (5A, 5B) É REALIZADO PELA ACÇÃO DA MOLA (6) . A ABERTURADAS MAXILAS É MECANICAMENTE TRANSMITIDA AO ELEMENTO SENSOR CONTIDO NO INVÓLUCRO DOSISTEMA ELECTRÓNICO (8) ATRAVÉS DO DESLOCAMENTO DA EXTREMIDADE ANTERIOR DO BRAÇOINFERIOR 4A E POSTERIORMENTE AOS MEIOS INFORMÁTICOS. OS BOTÕES (7A, 7B) PERMITEMAO UTILIZADOR CONTROLAR A EVOLUÇÃO DO PROGRAMA COMPUTACIONAL. ESTE DISPOSITIVOSERÁ ÚTIL SEMPRE QUE SEJA NECESSÁRIA A AVALIAÇÃO DA GORDURA E DENSIDADE CORPORAIS,PARTICULARMENTE IMPORTANTE NAS ÁREAS DE NUTRIÇÃO, DESPORTO, VETERINÁRIA E TAMBÉMSAÚDE EM GERAL

Mastery Profiling through Entity Linking: to Support Project Team Formation in Higher Education

Computer-supported group formation enables educators to assign students to project teams. The focus in this paper is placed on gathering data about student attributes that are relevant in the context of specific course projects. We developed a method that automatically produces learner models from existing documents, by linking students to topics and estimating the levels of skill, knowledge, and interest that students have in these topics. The method is evaluated in an experiment with student participants, wherein its performance is measured on two levels. Our results demonstrate that it is possible to link students to topics with high precision, but suggest that estimating mastery levels is a more challenging task

Designing physics game to support inquiry learning and to promote retrieval practice

Instruction in physics aims at achieving two goals: the acquisition of body of knowledge and problem solving skills in physics. This requires students to connect physical phenomena, physics principles, and physics sym-bols. Computer simulation provides students with graphical model that unites phenomenon and principles in physics. However, such minimally guided approach may harm learning since it overburdens the working mem-ory. Also, simulation is inadequate in promoting problem solving skills since students need to exercise with a variety of physics problems. Intelligent tutoring systems (ITS), in contrast, train students in solving physics problems. In this paper, we designed an online puzzle game in physics that combines simulation and pseudo-tutor (namely QTut). We addressed three challenges: extensibility, scalability, and reusability in designing our game. We conducted usability tests with 10 participants on the game prototype to study the user performances and perceptions for improvement. The results indicate the game as educative and moderately entertaining. The use of scaffolding in the game positively contributed to the game learning experience. Moreover, the game GUI expressed information well that made the game understandable, even with little instructions
