Stefano Filippi
Intelligent Information Management (IIM) , 2011, DOI: 10.4236/iim.2011.31004
Abstract: Design for manufacturing, design for assembly, and, in general, design for X, are methods helping an effective generation of industrial products. In parallel with the development of these methods, the research about usability engineering has generated many important results, both from the design, and the evaluation and testing points of view. The research described in this paper aims at evaluating the feasibility of the integration of two new usability methods, the design for innovative usability - DFIU -, and the integrated method for usability evaluation and testing - IMUET -, in an existing design for X named design guidelines collaborative framework - DGLs-CF -. Indeed, the DGLs-CF is a design for multi-X method, given that it covers both the manufacturing and the verification phases of the industrial product lifecycle. All these methods are currently under development by the author’s research group. To evaluate this feasibility, the first task of the research aims at describing and classifying the components of the three methods. Next, these components are semantically related to each other. Finally, the last activity verifies the compatibility between the components of the two usability methods and the data structures of the DGLs-CF to check the feasibility from the implementation point of view. The result of this research will consist of precise indications both for the development of a design for multi-X collaborative framework covering homogeneously the design, manufacturing, verification, and use phases of the industrial product lifecycle, and to be used as a reference for researchers interested in considering the integration of usability issues in their design tools, methods, and processes.

Abstract: Em três experimentos de campo, avaliaram-se os efeitos da calagem, da aduba o de plantio e de N em cobertura, para o feijoeiro comum. No primeiro experimento, testaram-se doses de calcário (0, 3, 6, 9, 12, e 15 t ha-1); no segundo, a resposta de cinco cultivares/linhagens de feijoeiro (Aporé, Carioca, Novo Jalo, MA534657 e MA5346662) à aplica o no sulco de plantio de 200, 400 e 600 kg ha-1 do fertilizante 4-30-16 mais 30 kg ha-1 de N em cobertura aos 25 dias após germina o, e no terceiro, as doses de N (0, 30, 60, 90 e 120 kg ha-1) aplicadas em cobertura a intervalos de dez dias, a partir dos 20 até aos 70 dias após a emergência das plantulas. A dose de 30 kg ha-1 foi parcelada em uma e duas vezes, e as demais doses, em duas, três e seis vezes. A calagem aumentou a absor o de N, P, K, Ca, Mg e Cu e a produtividade do feijoeiro em até 37%. A cultivar Aporé foi a mais produtiva e a que mais respondeu à aduba o. Com exce o da Carioca, as produtividades máximas das demais cultivares/linhagens foram alcan adas com a dose de 400 kg ha-1 de fertilizante mais 30 kg ha-1 de N em cobertura. Houve resposta até a dose máxima testada de 120 kg ha-1 de N, atingindo produtividade máxima de 3.170 kg ha-1. O parcelamento de N em cobertura n o afetou a produtividade do feijoeiro.
Using Rapid Prototyping Data to Enhance a Knowledge-Based Framework for Product Redesign  [PDF]
Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.21001
Abstract: The particular characteristics of Rapid Prototyping technologies, both in terms of constrains and opportunities, often require the reconfiguration of the product model to obtain the best compliance with the product functionalities and performances. Within this field of research, a knowledge-based tool named Design GuideLines Collaborative Framework (DGLs-CF) was developed to support both the designers defining the product consistently with the manufacturing technologies and the manufacturers defining the building setup consistently with the product requirements. Present work is focused on enhancing the DGLs-CF knowledge base and on updating the DGLs-CF knowledge management by using the information gathered on some RP technologies. The added-value of this research is represented by an improvement in the Redesign/Reconfig- uration Package, the final result of the DGLs-CF adoption. This is a list of actions to be performed on the product model and on the process parameters to avoid the limitations of the technology and to exploit at best its opportunities.
Classification and Selection of Prototyping Activities for Interaction Design  [PDF]
Stefano Filippi, Daniela Barattin
Intelligent Information Management (IIM) , 2012, DOI: 10.4236/iim.2012.44022
Abstract: Because of the evolution of markets and technologies, prototyping concerns should be kept updated almost day by day. Moreover, user centered design moves the focus towards interaction issues. Prototyping activities matching such characteristics are already available, but they are not so diffused in the industrial domain. This is due to many reasons; an important one is that a rigorous classification of them is missing, as well as an effective helping tool for the selection of the best activities, given the design context. The research described in this paper aims at defining a new classification of prototyping activities, as well as at developing a selection algorithm to choose the best ones in an automatic way. These goals are pursued by defining a set of characteristics that allow describing accurately the prototyping activities. The resulting classification is made by five classes, based on eighteen characteristics. This classification is exploited by the first release of an algorithm for the selection of the best activities, chosen in order to satisfy design situations described thanks to a different set of eleven indices. Five experiences in the field have been used up to now as a starting point for validating the research outcomes.

Abstract: Palicourea rigida H.B.K. (Rubiaceae), a medicinal species commonly known as douradinha, has wide distribution across ecosystems in Central and South America. This species exhibits seed dormancy delaying germination until optimal conditions for seedling growth and development are in place. While dormancy ensures species survival, it also presents a technical problem for developing P. rigidas plant production program. Thus, the objective of this study was to investigate if secondary metabolites present in seeds influence the seed dormancy of P. rigida. Mature fruits were harvested from the native habitat, in the savanna region of the State of Minas Gerais during February 2009, 2010 and 2011. The content of phenolic compounds in the seed of P. rigida was measured, and the allelopathic effects were assessed using the germination of lettuces as model to detect phytotoxicity. The P. rigida seeds geminated at rates varying between 7% and 31% with a Seed Germination Index (SGI) of 0.09. Data suggest that the phenolic compounds present in the seeds may be

LVDC: An Efficient Energy Solution for On-Grid Photovoltaic Applications  [PDF]
Anis Ammous, Hervé Morel
Smart Grid and Renewable Energy (SGRE) , 2014, DOI: 10.4236/sgre.2014.54007

In this paper some photovoltaic, PV, conversion chains architectures for on-grid applications have been proposed and the advantage of the direct use of a Low Voltage Direct Current (LVDC) bus for the DC loads has been shown. The evaluation of the efficiency of the proposed chains compared to the classical one was performed. It is shown that LVDC use instead of standard AC plugs, in numerous applications, is promising in future. The registered annual saved energy can exceed 25% of the PV generated energy. This important rate, the need of better services at lower economic cost and environmental burden will incite to make reflection about industry and supplies’ future standards.
