Temporal-space-transforming pulse-shaping system with a knife-edge apparatus for a high-energy laser facility

For the first time to our knowledge, in a high-energy laser facility with an output energy of 454.37 J, by using a temporal-space-transforming pulse-shaping system with our own design of a knife-edge apparatus, we obtained a quasi-square laser pulse. (c) 2005 Optical Society of America.

O despertar do budismo no ocidente no século XXI: contrbuição ao debate

Esta tese apresenta como um dos seus aspectos fundamentais a compreensão de outra cultura, outra versão, outro conjunto de valores: o pensamento indiano, berço da Ahamkãra a consciência individual, o eu e das práticas ascéticas de origem pré-ariana e autóctone. No interior dessa tradição, foram escolhidos os ensinamentos do Buddha Shãkyamuni, por sua absoluta originalidade na concepção da individualidade, transformando radicalmente as concepções de subjetividade existentes em sua época. O intuito, ao buscar uma tradição em tudo diferente da nossa, é, por dirigir o foco para o mais contrastante, iluminar nossa própria tradição, enriquecer o campo de discussão das novas matrizes de subjetivação em nossa sociedade ocidental pós-moderna e globalizada. Com essa abordagem objetiva-se contribuir para o debate em torno do despertar do budismo ocidental, no séc. XXI, lançando algumas linhas de reflexão que auxiliem, por um lado, a contextualizar esse acontecimento, e, por outro, a ampliar o debate sobre as questões relativas à noção de sujeito, utilizada pelos teóricos da psicanálise, através da apresentação de uma outra versão, a do eu budista. A comparação entre uma forma de individualidade oriunda de uma sociedade tradicional e holista e a forma da individualidade contemporânea, oriunda de uma sociedade secularizada e individualista, é possível através do que Harpham denomina imperativo ascético, uma força estruturante primária e transcultural. Nesse sentido visualiza-se uma relação entre as práticas ascéticas e a construção do eu. Segundo Mauss, o eu também é uma categoria universal, presente em todas as culturas. Assim como se encontram variações sobre o repertório das práticas ascéticas disponíveis em diferentes culturas, encontram-se variações na forma da subjetividade, de acordo com o seu solo cultural e sua paisagem mental. Fizemos uma conexão entre as práticas ascéticas indianas e o que denominamos de identificação mística, a partir da qual foi possível inferir essa imbricação entre ascetismo, construção e sacralização do eu nos primórdios da civilização indiana. Com o budismo ocorre uma espécie de descentramento, a sacralização é estendida a todo o cosmo, as práticas de meditação sintonizam com todos os seres, com todos os animais, para eliminar as causas do sofrimento. O budismo nasce com uma vocação universalista e leva para fora das fronteiras da Índia esse eu construído a partir dos conceitos da Ãhimsa, a não-violência, e da noção de ausência de existência inerente, inscritos no pensamento budista há dois mil e quinhentos anos, despertando o interesse do ocidente após um longo período de obscurecimento.

Transforming aquatic agricultural systems towards gender equality: a five country review

Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income. Improving the livelihood security and wellbeing of the estimated 250 million poor people dependent on AAS in Bangladesh, Cambodia, the Philippines, the Solomon Islands and Zambia is the goal of the Worldfish Center-led Consortium Research Program (CRP), “Harnessing the development potential of aquatic agricultural systems for development.” One component expected to contribute to sustainably achieving this goal is enhancing the gender and wider social equity of the social, economic and political systems within which the AAS function. The CRP’s focus on social equity, and particularly gender equity, responds to the limited progress to date in enhancing the inclusiveness of development outcomes through interventions that offer improved availability of resources and technologies without addressing the wider social constraints that marginalized populations face in making use of them. The CRP aims to both offer improved availability and address the wider social constraints in order to determine whether a multi-level approach that engages with individuals, households and communities, as well as the wider social, economic and political contexts in which they function, is more successful in extending development’s benefits to women and other excluded groups. Designing the research in development initiatives to test this hypothesis requires a solid understanding of each CRP country’s social, cultural and economic contexts and of the variations across them. This paper provides an initial input into developing this knowledge, based on a review of literature on agriculture, aquaculture and gender relations within the five focal countries. Before delving into the findings of the literature review, the paper first justifies the expectation that successfully achieving lasting wellbeing improvements for poor women and men dependent on AAS rests in part on advances in gender equity, and in light of this justification, presents the AAS CRP’s conceptual framew

Evaluating the impacts of iteration on PD processes by transforming task network models into System Dynamics models

Iteration is unavoidable in the design process and should be incorporated when planning and managing projects in order to minimize surprises and reduce schedule distortions. However, planning and managing iteration is challenging because the relationships between its causes and effects are complex. Most approaches which use mathematical models to analyze the impact of iteration on the design process focus on a relatively small number of its causes and effects. Therefore, insights derived from these analytical models may not be robust under a broader consideration of potential influencing factors. In this article, we synthesize an explanatory framework which describes the network of causes and effects of iteration identified from the literature, and introduce an analytic approach which combines a task network modeling approach with System Dynamics simulation. Our approach models the network of causes and effects of iteration alongside the process architecture which is required to analyze the impact of iteration on design process performance. We show how this allows managers to assess the impact of changes to process architecture and to management levers which influence iterative behavior, accounting for the fact that these changes can occur simultaneously and can accumulate in non-linear ways. We also discuss how the insights resulting from this analysis can be visualized for easier consumption by project participants not familiar with simulation methods. Copyright © 2010 by ASME.

A novel process for transforming sheet metal blanks: Ridged die forming

Up to 20% of all sheet metal produced is scrapped as blanking skeletons. A novel process is therefore designed and examined, aiming to transform tessellating 'pre-blanks' in-plane into the real blanks required for stamping. Prior to blanking, the sheet is formed with a set of ridged dies, from which pre-blanks are cut and then flattened into true blanks. Several different approaches to designing ridged dies are evaluated by simulation and experiment, and the best results demonstrate a potential reduction in blanking yield losses for can-making from 9.3% to 6.9%. © 2013 CIRP.

Transforming kelp into a marine bioreactor

The past decade has seen the genetic engineering of various types of seaweed. To date, genetic transformation studies have been carried out in several seaweeds, including the red seaweeds Porphyra, Gracilaria, Grateloupia, Kappaphyclus and Ceramium and the green seaweed Ulva. A genetic transformation model system has been established in the most commonly cultivated seaweed, the brown seaweed Laminaria japonica (kelp), based on the transfer of technology used in land plant transformation and also by modulating the seaweed life cycle. This model showed the potential for application of transgenic kelp to the production of valuable products and an indoor cultivation system for transgenic kelp was proposed, taking into account necessary factors for bio-safety. In this review, the establishment at use of the kelp transformation model is introduced, highlighting the potential for transforming kelp into a marine bioreactor.
