Microsoft Frontpage 2000 Applications in Computer Hardware Support Information Presentation Assembly

Computer hardware is in great demand by the hobies and assembler, Karen canchoose their own hardware is required in accordance with the needs and abilities.However, in choosing computer hardware, the price is not always a major factor inthe quality of the computer hardware. The author tries to help by providinginformation on computer hardware that can be used as a material consideration.Based on the results of a questionnaire distributed by the author, the constraints facedtoday is the hobies and assemblers feel difficulty in choosing a motherboard andknow the price of computer hardware.Using Microsoft FrontPage 2000, the authors make a home page for information oncomputer hardware in Indonesian language. So that the hobies and assembler canview this information through the internet media.As there are several things that must be considered by the webmaster in designinghome pagedengan using Microsoft FrontPage 2000, which hit counters, search formsand guest book. We make this information, the assembler can know hobies andhardware information and the price of hardware

The contribution of the new technologies to the 21st - Century Design

In the past the market economy was dominated by the local and regional design,characterized for strong links to the customs, traditions and natural resources from eachregion.As the consequence of the technological advances and the growing needs of consumption,at present, products are manufactured based on economical, functional and marketingcriterions, which means that their design is very offset from the regional and local signs.Between the challenges that characterize the actual economy, one highlights the existenceof more market niches, product variations and shorter life cycles. To survive in this economy,marked by the competition and the globalisation, one search to imply in product developingprocess, the design, engineering, marketing and production department, that composes aknown industrial methodology called concurrent or simultaneous engineering.In this article, one intends to exhibit the applications and advantages of the newtechnologies, like Rapid Prototyping (RP), that are valuable tools of the concurrentengineering and to analyse the specific implications in the design history and teaching.RP is a family of modern technologies that generate three-dimensional solid objects undercomputer control. Besides its designation be reported to the first major application that isindustrial prototyping, the RP equipments also allow the rapid tooling and the directmanufacture of small series or single products.Nowadays, the commercialisation of RP equipments, termed concept modellers or 3Dprintersis in great expansion. Although these machines use a very reduced class of cheapmaterials with poor mechanical characteristics, they allow the designers to verify and quicklytest the ideas that they are developing during the creative process. The designer can realize inplenitude the iterative process of creation without the traditional economical and materialslimitations, being enough to send the CAD file directly to the RP equipment placed in aoffice, like an usual inkjet printer. So it is possible to test new ideas with better accuracybefore its concretisation, avoiding misunderstandings and delays and inciting the positivecriticism through the involvement of the technical staff from all the related departments.Particularity, faced to the challenges due to the globalisation, the traditional and regionalindustries will find in these technologies the means that they need to ensure its own futuresurviving.This presentation is divided in the following sections:- Innovation loop in the past and in the present. The iterative process.- New technologies available to the design and the designers: Rapid Prototyping andInternet.- Design Pedagogy: new challenges in the formation of future generations of designers.- Conclusions and future trends

Indirect rapid tooling with aluminium and milled fibre reinforced resins

It is well known that Rapid Prototyping (RP) and Rapid Tooling (RT) are fundamental technologies to reduce the time tomarket and consequently increase productivity and competitiveness of companies working in different industrial sectors.RT with epoxy resins is presently accepted as an established process of indirect rapid tooling. However, patents,processing difficulties and companies limitations disable a wider implementation of this technology.This paper presents the experimental results of a detailed work, conducted at INEGI, to manufacture moulds for plasticinjection, with tailored properties, using RP models and aluminium filled and fibres reinforced epoxy resins

The effect of aluminium granulometry on the behaviour of filled epoxy resins for rapid tooling

Aluminium filled epoxies moulds have beenused in indirect rapid tooling. These moulds, whichhave a low cost processing, are very competitive,when applied in the manufacturing of low volumeseries.The geometry and the size distribution of thealuminium particles affect significantly the powderpacking density, the resin ratio, the thermalconductivity, the curing time, the homogeneity andthe mechanical characteristics of the tool.Using three high temperature epoxy resins itwas possible to understand the resin behaviour inthe presence of the aluminium filler and formulatefilled resins with the best compromise ofmechanical, thermal and processing performance

Universidade-Indústria: transferência de tecnologia em engenharia mecânica

A inovação nas pequenas e médias empresas industriais do ramo da Engenharia Mecânica é muitas vezes inexistenteou incipiente, podendo ser facilmente incrementada através de um estreito relacionamento e cooperação com asUniversidades e/ou os seus Institutos de Interface. Neste contexto, a Universidade do Porto, através do Departamentode Engenharia Mecânica e Gestão Industrial da Faculdade de Engenharia, fundou em 1986 o INEGI - Instituto deEngenharia Mecânica e Gestão Industrial, com a missão de reforçar a cooperação entre esta Universidade e o meioempresarial. O INEGI participa activamente, há 21 anos, no desenvolvimento da indústria nacional contribuindo comconhecimento e competências distintas na área da Engenharia Mecânica e Gestão Industrial, assumindo a missão de:Contribuir para o aumento da competitividade da indústria nacional através da investigação e desenvolvimento,demonstração, transferência de tecnologia e formação nas áreas de concepção e projecto, materiais, produção,energia, manutenção, gestão industrial e ambiente. Desde a sua criação, o INEGI tem tido um crescimentosustentado, tendo desenvolvido mais de 1300 projectos para organizações públicas e privadas, estando nestemomento numa fase de internacionalização, através do estabelecimento de protocolos e projectos conjuntos cominstituições internacionais.Esta comunicação pretende demonstrar as vantagens que as empresas podem obter, através de uma ligação ásUniversidades e Institutos de Interface, no desenvolvimento de materiais, produtos e processos tecnológicos,permitindo assim aumentar a sua competitividade. As áreas de intervenção dos projectos inovadores aqui focadosabrangem uma grande variedade de temas multidisciplinares, desde as energias renováveis, desenvolvimento deprocessos tecnológicos e sistemas mecânicos, materiais compósitos, prototipagem rápida e tecnologias avançadas deprodução e gestão industrial

Chlormequat selective electrodes: construction, evaluation and application at FIA systems

A flow injection analysis (FIA) system having a chlormequat selective electrode is proposed. Several electrodes with poly(vinyl chloride) based membranes were constructed for this purpose. Comparative characterization suggestedthe use of membrane with chlormequat tetraphenylborate and dibutylphthalate. On a single-line FIA set-up, operating with 1x10-2 mol L-1 ionic strength and 6.3 pH, calibration curves presented slopes of 53.6±0.4mV decade-1 within 5.0x10-6 and1.0x10-3 mol L-1, andsquaredcorrelation coefficients >0.9953. The detection limit was 2.2x10-6 mol L-1 and the repeatability equal to ±0.68mV (0.7%). A dual-channel FIA manifold was therefore constructed, enabling automatic attainment of previous ionic strength andpH conditions and thus eliminating sample preparation steps. Slopes of 45.5±0.2mV decade -1 along a concentration range of 8.0x10-6 to 1.0x10-3 mol L-1 with a repeatability ±0.4mV (0.69%) were obtained. Analyses of real samples were performed, and recovery gave results ranging from 96.6 to 101.1%
