The Potsdam Open Source Radio Interferometry Tool (PORT)
2021
The Potsdam Open Source Radio Interferometry Tool (PORT) is the very long baseline interferometry (VLBI) analysis software developed and maintained at the GFZ German Research Centre for Geosciences. Chiefly, PORT is tasked with the timely processing of VLBI sessions and post-processing activities supporting the generation of celestial and terrestrial reference frames. In addition, it serves as a framework for research and development within the GFZ's VLBI working group and is part of the tool set employed in educating young researchers. Starting out from VLBI group delays, PORT estimates station and radio sources positions, as well as Earth orientation parameters, tropospheric parameters, a…
Integrated System for Monitoring the Tool State Using Temperature Measuring by Natural Thermocouple Method
2014
The intensive developments of intelligent manufacturing systems in the last decades open the large possibilities of more accurate monitoring of the metal cutting process. One of the most important factors of the process is the tool state given by the rate of the tool wear, which is the result of a lot of influences of almost all cutting parameters. The modern tool monitoring systems relieved that the accuracy of the results increases when using a combination of surveyed signals such as: vibrations, power consumption, acoustic emission, forces or tool temperature. Combining the output signals in a monitoring function using the neural network method gives the best results when using on-line m…
Cutting Vibrations
2008
Chapter 8 provides comprehensive engineering knowledge regarding cutting vibrations, their typical sources in machining operations, and methods of their elimination to prevent negative influence on the surface finish (chatter marks). The classification of cutting vibrations including free, forced, and self-excited vibrations is discussed, and all possible sources and mechanisms of all types of cutting vibrations are specified and characterized. The regeneration of surface waviness, which is the predominant mechanism of chatter, is outlined for turning and milling operations. The stability of machining operations based on the stability lobe diagrams is highlighted and their practical applica…
Visual Tools in Virtual Reality: Complex Environment
1994
In this paper, we analyse an integrated system able to merge graphical and vision technique in order to improve virtual space environment. Virtual space is characterized by Dynamic Visual Icons and Virtual Reality for arising a hererogeneous environment. Essentially, we propose a fusion technique between visual icon and virtual space, where their integration is supported by Visual lcon Grammar (VIG) working on Dynamic lcon and Visual World. VIG allows to test the actions of the Dynamic Icon on the active Visual Word metaphor at the lime "t", and the different rage of transactions between user and VW(visual query, view and brows of under-world,... ). Moreover, user can define, modify and rem…
Thermographic imaging tool for children fracture detection
2016
The feasibility of thermographic imaging to diagnose pediatric fractures has been studied in the last years. The advantages lie in being a cost-effective, non-harmful, non-contact and non-invasive technique, since ionizing radiations are not used to get the image. Once the pictures of the affected limb are taken, the processing becomes necessary. In order to reduce the waiting time, a software tool has been developed to provide a diagnosis shortly after taking the image. Sin financiación No data (2016) UEV
A Decision Support Tool for Water and Energy Savingin the Integrated Water System
2015
Abstract In the last decades, a growing attention on energy saving associated with water resources usage and leakages reduction has been recorded at both national and international level. Scientific research has focused on implementation of several methodologies aimed at the understanding of energy transformation processes occurring in the integrated water system. The main concern is then identifying energy impacts associated to each macro-area of integrated water system, such as collection, treatment and distribution, and analysing the potential interactions between them. Unfortunately, only overall energy consumptions are usually available at national level. The main objective of the pape…
Efficient analysis of waveguide filters by the integral equation technique and the BI-RME method
2003
This paper presents the study of rectangular waveguide filters with rounded corners in the cross-section of the waveguides. These components are suitable for low-cost mass production and can be rigorously analyzed by efficient CAD tools. The analysis approach described in this paper is based on the integral equation technique in conjunction with the boundary integral-resonant mode expansion method. Two representative examples are also reported.
Fast and accurate analysis and design of substrate integrated waveguide (SIW) filters
2007
This paper describes the application of the boundary integral-resonant mode expansion (BI-RME) method to the accurate modelling of substrate integrated waveguides (SIW). The new formulation fully exploits the particular geometry of this class of structures, thus providing a very efficient analysis method to be used within CAD tools of SIW filters. The advantages of this method have been proved with the successful design of two filters operating in the microwave and millimeter-wave bands.
Life Cycle Assessment in the Wine Sector
2015
Currently, stakeholders’ increasing attention to quality is driving the wine sector to rethink and change its own production processes. Amongst product quality dimensions, the environment is gaining ever-growing attention at various levels of policy-making and business. Given its soundness, the use of Life Cycle Assessment (LCA) has become widespread in many application contexts. Apart from applications for communication purposes, LCA has also been used in the wine sector to highlight environmental hot spots in supply chains, to compare farming practices and to detect improvement options, inter alia. Case studies whose focus is the wine industry abound in high quality publications. This Cha…
Educación intercultural, diversidad y creatividad en el aula a través del teatro: los títeres
2015
La educación intercultural y el tratamiento de la diversidad en la escuela son sin duda algunos de los aspectos de la educación sobre los que más se ha escrito en las últimas décadas. Con el presente trabajo pretendemos hacer un recorrido por los planteamientos más actuales en la educación intercultural, así como la profundización en la idea de creatividad y en el trabajo colaborativo como formas eficaces de afrontar el reto que nos plantea la diferencia. Finalmente, propondremos literatura, concretamente el teatro de títeres, como herramienta didáctica óptima para el trabajo intercultural en todos los niveles educativos, partiendo de la valoración positiva de la diversidad en sus múltiples…
