Knowledge creation and visualisation by using trade-off curves to enable set-based concurrent engineering

The increased international competition forces companies to sustain and improve market share through the production of a high quality product in a cost effective manner and in a shorter time. Set‑based concurrent engineering (SBCE), which is a core element of lean product development approach, has got the potential to decrease time‑to‑market as well as enhance product innovation to be produced in good quality and cost effective manner. A knowledge‑based environment is one of the important requ irements for a successful SBCE implementation. One way to provide this environment is the use of trade‑off curves (ToC). ToC is a tool to create and visualise knowledge in the way to understand the relationships between various conflicting design parame ters to each other. This paper presents an overview of different types of ToCs and the role of knowledge‑based ToCs in SBCE by employing an extensive literature review and industrial field study. It then proposes a process of generating and using knowledg e‑based ToCs in order to create and visualise knowledge to enable the following key SBCE activities: (1) Identify the feasible design space, (2) Generate set of conceptual design solutions, (3) Compare design solutions, (4) Narrow down the design sets, (5) Achieve final optimal design solution. Finally a hypothetical example of a car seat structure is presented in order to provide a better understanding of using ToCs. This example shows that ToCs are effective tools to be used as a knowledge sou rce at the early stages of product development process

The GRAVITY fringe tracker: correlation between optical path residuals and atmospheric parameters

After the first year of observations with the GRAVITY fringe tracker, we compute correlations between the optical path residuals and atmospheric and astronomical parameters. The median residuals of the optical path residuals are 180 nm on the ATs and 270 nm on the UTs. The residuals are uncorrelated with the target magnitudes for Kmag below 5.5 on ATs (9 on UTs). The correlation with the coherence time is however extremely clear, with a drop-off in fringe tracking performance below 3 ms.Comment: submitted to SPIE Astronomical Telescopes & Instrumentation 201

Primeiro registro de Eudorylas schreiteri (Shannon) (Diptera: Pipunculidae) como parasitóide da cigarrinha do milho (Hemiptera: Cicadellidae) na Argentina, e uma tabela dos hospedeiros de pipunculídeos na região neotropical

The big-headed fly Eudorylas schreiteri (Shannon) is recorded for the first time as an endoparasitoid of the corn leafhopper Dalbulus maidis (DeLong & Wolcott) in Northern Argentina. A table of known Neotropical pipunculid-host associations is presented.Eudorylas schreiteri (Shannon) é registrada pela primeira vez como endoparasitóide da cigarrinha do milho Dalbulus maidis (DeLong & Wolcott) no norte da Argentina.

Sancho Panza, otro candidato más en La elección de los alcaldes de Daganzo: algunos paralelismos entre el entremés cervantino y el Quijote

A pesar de las diferencias existentes entre la poesía, la prosa y el teatro, es posible –como es de todos sabido– encontrar en ocasiones similitudes entre ellos. Esto lo podemos percibir de una manera clara en algunas de las obras de Cervantes. Sucede así en el Romance de los celos compuesto por este mismo y recogido en el Romancero general de 1600, y la comedia de La casa de los celos en el entremés de La cueva de Salamanca y el episodio de la aventura de la cueva de Montesinos en la Parte II del Quijote, puesto que ambos subyacen en la alegoría de la cueva. Y «el engaño a los villanos» une el episodio de Maese Pedro del Quijote de 1615 y el entremés del Retablo de las maravillas. Estos son tan sólo algunos ejemplos, de los muchos que podemos encontrar. Algunos de los paralelismos se pueden deber a puras coincidencias, aunque no siempre, pues en algunos casos serán las claves para descifrar la esencia artística del autor alcalaíno. En la presente comunicación observamos las similitudes existentes entre el entremés de La elección de los alcaldes de Daganzo y El Ingenioso Hidalgo Don Quijote de la Mancha

Atomic layer deposition-based tuning of the pore size in mesoporous thin films studied by in situ grazing incidence small angle x-ray scattering

Atomic layer deposition (ALD) enables the conformal coating of porous materials, making the technique suitable for pore size tuning at the atomic level, e.g., for applications in catalysis, gas separation and sensing. It is, however, not straightforward to obtain information about the conformality of ALD coatings deposited in pores with diameters in the low mesoporous regime (< 10 nm). In this work, it is demonstrated that in situ synchrotron based grazing incidence small angle x-ray scattering (GISAXS) can provide valuable information on the change in density and internal surface area during ALD of TiO2 in a porous titania film with small mesopores (3-8 nm). The results are shown to be in good agreement with in situ x-ray fluorescence data representing the evolution of the amount of Ti atoms deposited in the porous film. Analysis of both data sets indicates that the minimum pore diameter that can be achieved by ALD is determined by the size of the Ti-precursor molecule

Ancora sulla diaspora dei gesuiti spagnoli in Italia. Il contributo di Terreros e di Hervás alla grammaticografia italo-spagnola del settecento

Risulta interessante sottolineare la notevole importanza che la diaspora dei gesuiti spagnoli in Italia ha rappresentato, anche se forzosamente, come fenomeno di contatto e di reciproca influenza fra cultura spagnola ed italiana. Fra i molti gesuiti che hanno contribuito a costituire questa sorta di ponte fra le due culture, vorrei in questa sede ricordare due figure rilevanti nella linguistica settecentesca, Esteban de Terreros y Pando e Lorenzo Hervás y Panduro. All’interno della loro vastissima produzione di autori poligrafi, mi interessa in particolare rilevare il loro contributo in ambito grammaticografico, dal momento che entrambi composero testi grammaticali per lo studio e l’insegnamento dell’italiano a ispanofoni, vale a dire le Reglas acerca de la lengua toscana (Terreros 1771) e la Gramática de la lengua italiana (Hervás 1797).Risulta interessante sottolineare la notevole importanza che la diaspora dei gesuiti spagnoli in Italia ha rappresentato, anche se forzosamente, come fenomeno di contatto e di reciproca influenza fra cultura spagnola ed italiana.
