This paper addresses the use of structural dynamics concepts applied to virtual manufacturing. A review of vibration fundamentals is done using a single degree of freedom system. Then, a lab procedure to experimentally determine the frequency response functions and vibration modes of a steel beam by modal fitting is explained. An introduction to receptance coupling substructure analysis is then provided, using an example with two single-degree-of-freedom systems, which are assembled through a flexible coupling. Finally, milling dynamics concepts are introduced, and the stability lobe diagram for an up milling condition is developed. This work provides an explanation of how to use structural dynamics to select cutting parameters that will provide an optimized performance of a milling machine, allowing to maximize profit of the productive process. © 2014, Springer-Verlag France.

Poly(lactic acid) (PLA) is a compostable polymer derived from renewable food-derived sources (mainly starch and sugar beet) and possesses the highest potential for a commercial major scale production of renewable packaging materials. Since PLA is compostable and derived from sustainable sources, it can be envisaged as a promising material for the reduction of the enormous societal problems associated to solid waste disposal. ECLIPSE promotes a more sustainable and environmentally friendly approach to packaging, via the use of waste derived materials unrelated to fossil fuels and to the food chain. The main objective of ECLIPSE is to revalorize waste-derived products (algae biomass waste and plant and crustacean wastes) into novel packaging materials. The ECLIPSE approach intends to revalorize waste materials for the production of an algae-derived PLA matrix. In addition, ECLIPSE also seeks to reinforce such PLA matrix with functionalized nanofillers extracted from non-edible banana plant, almond shell and crustacean shell wastes. This project aims at decreasing both the production costs of both poly(lactic acid) and algae biodiesel, by increasing the added value of algae waste via its revalorisation into the production of lactic acid. To this purpose, the industrial partnership was designed to combine leading companies to supply the raw materials involved in the project, namely algae (ALGAENERGY), lactic acid (GALACTIC), PLA (FUTERRO), banana waste (BANACOL) and seafood waste (ANTARTIC), with sound research groups active on biopolymers and nanoparticle functionalisation and dispersion (UMONS, CIDETEC, FRAUNHOFER, LTU, UPV/EHU, UPB, PUC) and a global end user with multiple plastic packaging converting facilities. This consortium includes 9 partners from European institutions and 4 partners from South American SICA countries, all of them experts in their respective fields.

PRO-IDEAL PLUS PROmotion of an ICT Dialogue between Europe and America Latina extension towards Mexico, Colombia, Cuba and Costa Rica aims to strengthen the research dimension of Information Society policy dialogues in the target region, establishing a sustainable ICT research community and developing synergies. PRO-IDEAL PLUS will equally enhance the international cooperation of stakeholders within the target countries amongst themselves thus leveraging best practices e.g. from those countries that already enjoy an S&T agreement. It will do so by:\n\n- organising ICT Fora in order to facilitate the introduction of ICT research dimension into the regular policy dialogues in parallel to EU-LAC S&T events. These ICT Fora are continued via the Virtual ICT Dialogue space on the PRO-IDEAL PLUS platform. Complementary Round Tables will allow for informal discussions with stakeholders.\n\n- organising ICT Days with interactive workshops and coaching courses to stimulate, encourage and facilitate proactive participation of researchers in the ICT programme, based on the experience in the PRO-IDEAL project (www.pro-ideal.eu, involving AR, CL, BR, UY).\n\n- fostering pro-active cooperation between PRO-IDEAL PLUS and other research initiatives e.g. e-science networks (e.g. RedCLARA, GEANT2), ICT networks (e.g. ALETI) other INCO-NET projects, but also bilateral initiatives such as UEMEXCYT II.\n\n- drafting an ICT research Roadmap providing a shared insight and long-term visions for ICT cooperation\n\nThe above activities are carried out by an experienced partnership that has a proven track record in successful international projects: INMARK from Spain will co-ordinate the consortium; the European Multimedia Forum disposes of the network in the ICT sector and takes care of the dissemination strategy as well as the Web 2.0 tool; the partners in the target countries will act as hub implementing the project activities at local level.

The invention relates to a system for generating electrical energy from wind energy, said system being characterized in that the design makes use of small air currents and does not require a large amount of air in order to generate electrical energy or power. This system incorporates two generating technologies designed based on the vertical rotation axis concept, achieving movement that is independent of wind direction. The invention combines two technologies, namely: one based on drag forces, ideal for low speed conditions; and another based on lift force, which is best for high speed work.

A method to construct a family of strict Lyapunov functions, i.e., with negative definite derivative, for the super-twisting algorithm, without or with perturbations, is provided. This second order sliding modes algorithm is widely used to design controllers, observers and exact differentiators. The proposed Lyapunov functions ascertain finite time convergence, provide an estimate of the convergence time, and ensure the robustness of the finite-time or ultimate boundedness for a class of perturbations wider than the classical ones for this algorithm. Since the Lyapunov functions and their derivatives are quadratic forms, the operation with them is as simple as for linear time invariant systems. © 2011 IEEE.

A study of the speckle photo-electromotive force (PEMF) in a photorefractive sensor of amplitudes of micro-oscillations is presented. The experimental behavior of the first harmonic of the photocurrent generated as a function of the average speckle diameter and the oscillation amplitude of the speckle pattern is analyzed for a sensor implemented with a Bi 12SiO20 (BSO) crystal. For a given light intensity, a nearly constant value of the maximum amplitude of the first harmonic was experimentally observed for the range of speckle sizes considered. This experimental result and the linear dependence of the vibration amplitude yielding the maximum of the photocurrent as a function of the speckle diameter were appropriately described by the mathematical model considered. Results show the possibility of adequately selecting the speckle size to optimize the output of speckle PEMF-based sensors depending on the oscillation amplitude to be measured. © 2013 Elsevier B.V.

The invention is entirely in keeping with the industry of renewable energies, particularly those using kinetic energy from fluids. The invention comprises the non-conventional design of the shape or geometry of a rotor blade, such rotor being or not being coupled to a machine which generates power from the transformation of kinetic energy that a fluid in movement has. The fundamental purpose of the design is to improve the efficiency in which fluid kinetic energy is transformed, thus being able to obtain better power coefficient values and therefore better performance when generating power. Said rotor must have as a minimum two (2) blades (e) for the operation thereof and is primarily designed for wind power generation applications.


The present invention discloses a portable system for acquiring, processing, storage, diagnostics, remote alarm transmission and cardiac event in patients, which operates at a sampling rate of a minimum 1 kHz signals, making it quick and effective. The system is non-invasive and capable of detecting more than eight cardiac conditions, unlike other similar devices on the market.
