Embedding Monitoring Systems for Cured-In-Place Pipes
2017
This paper proposes a non-intrusive electrical measurement system for monitoring some relevant parameters in pipeline systems. Temperature and flow-rate are monitored, using MEMS sensors. The flow-rate is evaluated by measuring pipe vibration, with a 3 axis accelerometer, induced by turbulence when fluid flows within the tube. The sensors are embedded, during the curing process of the cured-in-place pipes, in the pipes wall making the system suitable to be installed in renewed or new pipeline. The first experimental results show that it may be possible to obtain, at low-cost, a fully monitored distribution network.
Evaluating European railway deregulation using different approaches
2012
Abstract There has recently been a great deal of interest in the impacts of the deregulating and restructuring measures in the European railway sector. A vast amount of literature is devoted to analyzing the effects of these deregulation and restructuring measures on efficiency and productivity and the results are not totally unambiguous. However, while most of the papers show that the introduction of competition within the sector (in both passenger and freight markets) has had a positive impact in terms of efficiency and productivity, the impact of vertical separation has produced different results in the literature. The contribution of this paper to the existing literature is twofold. Fir…
Micro-Machining
2017
This chapter provides comprehensive knowledge regarding the fabrication of micro-products and element of micro-electromechanical systems using various techniques and processes. Both well-established techniques such as micro-machining and new trends in improving micro-processes taking into account EDM, laser, FIB, LIGA and DRIE processes are overviewed. The background of micro-machining processes, including typical machining operations such as turning, milling and drilling and different construction materials, is outlined. Moreover, a special focus was made on new constructions, control systems and effective applications of micro-machining techniques. In addition, the focus was directed towa…

Towards micrometer sized core-shell actuators from liquid crystalline elastomers by a continuous flow synthesis
2012
We present here the successful preparation of liquid crystalline core-shell elastomers via a microfluidic double-emulsion process. The customized set-up allows for a temperature-controlled fabrication of the core-shell particles from a thermoresponsive mesogenic monomer. The nematic liquid crystalline shell is filled with a non-mesogenic core of silicone oil. To verify the core-shell structure with optical microscopy, we prepared particles with a colored core using a red dye. We were also able to micro-manipulate the particles and penetrate them with a small glass capillary to extract the liquid core.

New dental simulator for microsurgical training preliminary overview
2007
Objective: To present a new simulator designed at the Minimally Invasive Surgery Centre (Cáceres) which offers an integral, effective and viable training system that can be used for learning microsurgical techniques. Study design: A square methacrylate block was used. Animal jaws were fixed to the sides by means of butterfly screws. This block also has a drainage tube to facilitate the escape of fluids. Results: Excellent results were obtained using this simulator in microsurgical suturing training in dental, Oral and Maxillofacial Surgery Conclusions: We believe that this simulator is an essential component in microsurgical training. It is an ethically and morally valid training method wit…
Phosphatbedarf und Sch�den durch hohe Phosphatzufuhr
1959
Die wunschenswerte Hohe der Phosphatzufuhr fur den nicht schwer korperlich arbeitenden Menschen betragt 1–2 g im Tag. Bilanzversuche und statistische Auswertung des Lebensmittelkonsums zeigen, das eine in diesem Bereich gelegene Aufnahme auch in der Tat erreicht wird. Vielfach, insbesondere bei lacco-vegetabilen Ernahrungsformen, sind die Aufnahmen wesentlich groser.
Car sequencing versus mixed-model sequencing: A computational study
2014
Abstract The paper deals with the two most important mathematical models for sequencing products on a mixed-model assembly line in order to minimize work overload the mixed-model sequencing (MMS) model and the car sequencing (CS) model. Although both models follow the same underlying objective, only MMS directly addresses the work overload in its objective function. CS instead applies a surrogate objective using so-called sequencing rules which restrict labor-intensive options accompanied with the products in the sequence. The CS model minimizes the number of violations of the respective sequencing rules, which is widely assumed to lead to minimum work overload. This paper experimentally co…
Wavelength-multiplexing system for single-mode image transmission
1997
The expanding use of optical communication by means of optical fibers and the situation of drastically increasing amounts of data to be transmitted urge the exploration of novel systems permitting the transmission of large amounts of spatial information by fiber with smaller spatial resolution. An optical encoding and decoding system is suggested for transmitting one- or two-dimensional images by means of a single-mode fiber. The superresolving system is based on wavelength multiplexing of the input spatial information, which is achieved with diffractive optical elements. Preliminary experimental results demonstrate the capabilities of the suggested method for the one- and two-dimensional c…
