Identification Tool

Sustainable management and conservation of tropical trees and forests require accurate identification of tree species. Reliable, user-friendly identification tools based on macroscopic morphological features have already been developed for various tree floras. Wood anatomical features provide also a considerable amount of information that can be used for timber traceability, certification and trade control. Yet, this information is still poorly used, and only a handful of experts are able to use it for plant species identification. Here, we present an interactive, user-friendly tool based on vector graphics, illustrating 99 states of 27 wood characters from 110 Amazonian tree species belonging to 34 families. Pl@ntWood is a graphical identification tool based on the IDAO system, a multimedia approach to plant identification. Wood anatomical characters were selected from the IAWA list of microscopic features for hardwood identification, which will enable us to easily extend this work to a larger number of species. A stand-alone application has been developed and an on-line version will be delivered in the near future. Besides allowing non-specialists to identify plants in a user-friendly interface, this system can be used with different purposes such as teaching, conservation, management, and selftraining in the wood anatomy of tropical species.

When completed, the actual program of municipal wastewater abatment of Quebec will comprise, among many treatment stations, approximately 400 facultative aerated lagoons. This type of station needs some supervision to maintain a good performance. Failure to adequately supervise the process could result in partly treated waters, not meeting environmental regulations, being released, SEXTANG is a prototype of expert system developed to assist operators of these stations in their every day duties and to identify the causes of misfunctions and propose solutions. Four different functions are available: (i) diagnosis and solutions to identified problems, (ii) data record and processing of current parameters, (iii) sludge management, and (iv) information on environmental regulations, SEXTANG presents also a user friendly interface with functions like an explanation of questions asked by the system, a dictionary of wastewater treatment terminology, and the access, at any time during a consultation, to the values and answers given by the operator since the beginning of the consultation. Key words: expert system, wastewater treatment, facultative aerated lagoons, computer-assisted operation.

The Given

In conventional learning, teachers frequently face difficulties to deliver their materials due to limited time and practical materials in teaching network computer. Conventional teaching process, especially practical materials, has still not yet been optimal. Thus, computer and multimedia based learning is required to help the students. Besides it can reduce costs in practical materials procurement, the students can absorb the given knowledge well without thinking of the costs to buy the practical materials. Computer Assisted Instruction Method can present the learning using various media either by picture or video that can assist the effective learning process and simplify the students to manage the learning speed since it is combined with the multimedia. By doing this, the students can practice the lesson materials, study whenever and wherever they want. Compuer learning application prioritize user interface, user friendly, which can make the students be diligent and passionate in learning.

AbstractObjectives: To introduce and evaluate a computer assisted learning programme in undergraduate psychiatry (CAL-PSYCH).Methods: An interactive e-learning environment was created within the University College Dublin portal to assist students in acquiring the necessary skills in undergraduate psychiatry. The pilot phase consisted of providing their lectures on-line on the interactive site. Data were gathered from the last group of students in 2001 (pre-CAL-PSYCH) and the first group of students using CAL-PSYCH in 2002. We included assessment of percentage of students accessing the site, attendance rates at face-to-face lectures and tutorials, and also a feedback questionnaire from students who accessed the site.Results: All responders had used CAL-PSYCH. Students gave higher ratings for quality and interactivity of lectures compared with the pre-CAL-PSYCH curriculum. Students also expressed enthusiasm about CAL-PSYCH and encouraged us to develop it further.Conclusions: Computer-assisted learning environments such as CAL-PSYCH provide the opportunity to bring modern e-learning techniques to medical education, and may provide a new model for life-long learning in medicine.

RESUMO Com o aumento da oferta na rede mundial de computadores dos chamados Cursos On-line Massivos e Abertos, mais conhecidos por seu acrônimo em inglês MOOCs (Massive Online Open Courses), cria-se a necessidade de que se pesquise de maneira mais aprofundada sua dinâmica, sua pedagogia e sua estrutura a fim de que se possa estabelecer um juízo sobre as possibilidades de uso efetivo desta nova ferramenta para o ensino de línguas estrangeiras. Neste trabalho, situado no âmbito das pesquisas em CALL (Computer Assisted Language Learning), partimos da perspectiva da Teoria Conectivista, estabelecida, sobretudo, a partir dos estudos de Siemens e Downes, para analisar dois cursos de línguas estrangeiras na modalidade MOOC, oferecidos em diferentes plataformas digitais: o curso de espanhol para estrangeiros oferecido pela UNED em plataforma própria e o curso de mandarim para hispanofalantes veiculado pela plataforma UNIMOOC. Em ambos os casos, evidencia-se que os cursos não cumprem o que prometem, apresentando falhas no processo de ensino, sobretudo no que tange à necessidade de criar espaços propícios à interação. Este trabalho inscreve-se em uma proposta de pesquisa mais ampla, cujo objetivo é estabelecer critérios adequados para a criação de MOOCs para o ensino de línguas estrangeiras.

Radiation Scheme

Abstract. The Modular Earth Submodel System (MESSy) provides an interface to couple submodels to a basemodel via a highly flexible data management facility (Jöckel et al., 2010). In the present paper we present the four new radiation related submodels RAD, AEROPT, CLOUDOPT and ORBIT. The submodel RAD (with shortwave radiation scheme RAD_FUBRAD) simulates the radiative transfer, the submodel AEROPT calculates the aerosol optical properties, the submodel CLOUDOPT calculates the cloud optical properties, and the submodel ORBIT is responsible for Earth orbit calculations. These submodels are coupled via the standard MESSy infrastructure and are largely based on the original radiation scheme of the general circulation model ECHAM5, however, expanded with additional features. These features comprise, among others, user-friendly and flexibly controllable (by namelists) on-line radiative forcing calculations by multiple diagnostic calls of the radiation routines. With this, it is now possible to calculate radiative forcing (instantaneous as well as stratosphere adjusted) of various greenhouse gases simultaneously in only one simulation, as well as the radiative forcing of cloud perturbations. Examples of on-line radiative forcing calculations in the ECHAM/MESSy Atmospheric Chemistry (EMAC) model are presented.

Robinson Seismic's latest developments in seismic isolation includes a new device, the RoballTM, for seismically isolating structures during earthquakes. This advance is a new concept for seismic isolation based on the principle of the inverted pendulum. It consists of 'friction balls' or 'Roballs' moving between upper and lower spherical like cavities or flat plates. The Roballs are filled with a material which is able to provide the friction forces required to absorb the energy from numerous earthquakes while supporting the structure. The Roball technique is expected to enable light and in the future possibly heavy structures to be more economically seismically isolated. As part of a program to develop a user friendly 'seismic isolation system' a series of full-scale tests have been carried out on a number of possible designs including three approaches for vertical pressures of -1 MPa resulting in coefficients of friction of -0.1 to -0.4. In this paper we present the preliminary experimental results.
