Development of an Extended Product Lifecycle Management through Service Oriented Architecture.
Organised by: Cranfield UniversityThe aim of this work is to define new business opportunities through the concept of Extended Product
Lifecycle Management (ExtPLM), analysing its potential implementation within a Service Oriented
Architecture. ExtPLM merges the concepts of Extended Product, Avatar and PLM. It aims at allowing a
closer interaction between enterprises and their customers, who are integrated in all phases of the life cycle,
creating new technical functionalities and services, improving both the practical (e.g. improving usage,
improving safety, allowing predictive maintenance) and the emotional side (e.g. extreme customization) of
the product.Mori Seiki – The Machine Tool Company; BAE Systems; S4T – Support Service Solutions: Strategy and Transitio
ESTRATEGIAS GENÓMICAS PARA LA GENERACIÓN DE VARIEDADES DE SOJA RESISTENTES A Macrophomina phaseolina.
La podredumbre carbonosa es una de las enfermedades cuya presencia ha tenido un sostenido aumento en el paÃs, principalmente en ambientes cálidos y secos. Las estrategias de manejo incluyen métodos culturales y fungicidas, pero han proporcionado un control limitado (Mengistu et al., 2015). En este escenario, la resistencia genética puede ser el método más factible y sostenible para manejar la enfermedad. Con el uso de herramientas biotecnológicas es posible comprender la respuesta vegetal, las vÃas metabólicas y genes asociados, para posteriormente desarrollar marcadores moleculares que guÃen el mejoramiento hacia la obtención de variedades con mejor desempeño ante dicho patógeno. Como primer paso resulta indispensable la caracterización de la respuesta frente a la enfermedad en genotipos de comportamiento contrastante frente a dicha adversidad. Posteriormente, es indispensable la secuenciación y un análisis transcriptómico que permite dilucidar cuáles son los genes y las rutas metabólicas responsables del diferente comportamiento de los genotipos observado previamente
Characterization of the Hamamatsu R11265-103-M64 multi-anode photomultiplier tube
The aim of this paper is to fully characterize the new multi-anode
photomultiplier tube R11265-103-M64, produced by Hamamatsu. Its high effective
active area (77%), its pixel size, the low dark signal rate and the capability
to detect single photon signals make this tube suitable for an application in
high energy physics, such as for RICH detectors. Four tubes and two different
bias voltage dividers have been tested. The results of a standard
characterization of the gain and the anode uniformity, the dark signal rate,
the cross-talk and the device behaviour as a function of temperature have been
studied. The behaviour of the tube is studied in a longitudinal magnetic field
up to 100 Gauss. Shields made of a high permeability material are also
investigated. The deterioration of the device performance due to long time
operation at intense light exposure is studied. A quantitative analysis of the
variation of the gain and the dark signals rate due to the aging is described.Comment: 22 page
Speckled-speckle field as a resource for imaging techniques
Correlated states of light, both classical and quantum, can find useful applications in the implementation of several imaging techniques. Among the employed sources, pseudo-thermal states, generated by the passage of a laser beam through a diffuser, represent the standard choice. To produce light with a higher level of correlation, in this work we consider and characterize the speckled-speckle field obtained with two diffusers using both a numerical simulation and an experimental implementation. In order to discuss the potential usefulness of super-thermal light in imaging protocols, we analyze the behavior of some figures of merit, namely the contrast, the signal-to-noise ratio and the image resolution. The obtained results clarify the possible advantages offered by this kind of light, and at the same time better emphasize the reasons why it does not outperform pseudo-thermal light
Large area Si low-temperature light detectors with Neganov-Luke effect
Next generation calorimetric experiments for the search of rare events rely
on the detection of tiny amounts of light (of the order of 20 optical photons)
to discriminate and reduce background sources and improve sensitivity.
Calorimetric detectors are the simplest solution for photon detection at
cryogenic (mK) temperatures. The development of silicon based light detectors
with enhanced performance thanks to the use of the Neganov-Luke effect is
described. The aim of this research line is the production of high performance
detectors with industrial-grade reproducibility and reliability.Comment: 4 pages, 2 figure
First characterization of the Hamamatsu R11265 multi-anode photomultiplier tube
The characterization of the new Hamamatsu R11265-103-M64 multi-anode photomultiplier tube is presented. The sample available in our laboratory was tested and in particular the response to single photon was extensively studied. The gain, the anode uniformity and the dark current were measured. The tube behaviour in a longitudinal magnetic field up to 100 G was studied and the gain loss due to the ageing was quantified. The characteristics and performance of the photomultiplier tube make the R11265-103-M64 particularly tailored for an application in high energy physics experiments, such as in the LHCb Ring Imaging Cherenkov (RICH) detector at LHC
Calidad de aire en la ciudad de Rafaela
Dentro del ambiente urbano la calidad del aire es afectada fundamentalmente por presencia de sustancias que provienen de los procesos de combustión producidos en los vehÃculos de transporte público y privado. Los contaminantes primarios más importantes son CO, NOx, SO2, HC, y material particulado. En el presente trabajo se estudia la calidad del aire en zona céntrica de la ciudad de Rafaela, provincia de Santa Fe, Argentina. La ciudad de Rafaela se encuentra en la zona centrooeste de la provincia de Santa Fe. Su población es de 82.530 habitantes y cuenta con un parque automotor de alrededor de 59.679 vehÃculos.
