Procesado del ácido poliláctico (PLA) y de nanocompuestos PLA/montmorillonita en planta piloto: Estudio de sus cambios estructurales y de su estabilidad térmica
Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià (2010)Se aplican procesos de transformación y tratamiento de termoplásticos (inyección, extrusión-inyección y recocido) al ácido poliláctico (PLA) y a determinados nanocompues- tos PLA/montmorillonita, con objeto de estudiar las ... -
Aplicación de la mecánica de la fractura post-cedencia a polímeros
Universidad Simón Bolívar (2010)The Essential Work of Fracture (EWF) technique has been used for the ductile materials characterization, where yielding phenomenon occurs before crack propagation. The EWF method characterizes the post-yielding ... -
The Effectiveness of Metaphoric Resources in Graphic Interface Design
Common Ground Publishing (2010)This research is conducted in a moment when the emergence of new formats in Communic- ation Technologies fills a gap in an unpublished stage on the social, cultural and artistic practices. The information access and its ... -
New Resolution of the Unbalance Power According to Std. 1459
IEEE (2010)Harmonic distortion and load unbalances have been an important issue in the last few years, motivating a large number of studies in active power compensators used for the power network quality improvement. Following an ... -
Improved Shunt Active Power Compensator for IEEE Standard 1459 Compliance
IEEE (2010)This paper presents the simulated and experimental results of an improved shunt active power compensator (SAPC). The proposed power compensator achieves IEEE Standard 1459 compliance by using moving-window discrete Fourier ... -
Influence of processing on the ethylene-vinyl alcohol (EVOH) properties: Application of the successive self-nucleation and annealing (SSA) technique
Budapest University of Technology (2010)Films of EVOH copolymers, processed three times by twin-screw extrusion were prepared using a cast-film line. The variation on the melt flow rate (MFR) and rheological behaviour of the films were determined, as well as the ... -
Comparative study of nanocomposites of polyolefin compatibilizers containing kaolinite and montmorillonite organoclays
Wiley (2010-02)This work studied the morphology and physical properties of nanocomposites of different ethylene copolymers and functionalized polyethylenes with two different types of organoclays, to assess the potential application of ... -
Oxidation behaviour at 1123 K of AISI 304-Ni/Al-Al2O3/TiO2 multilayer system deposited by flame spray
Consejo Superior de Investigaciones Científicas (2011)The oxidation behaviour of alumina/titania (97/3, 87/13 and 60/40) ceramic coatings using a Ni-Al coupling layer was studied in a thermobalance. Both layers were deposited on an AISI 304 stainless steel base metal by the ... -
Maximal closed loop admissible set for linear systems with non-convex polyhedral constraints
Elsevier (2011)This paper deals with the computation of the maximal closed-loop admissible set for linear systems with non-convex polyhedral constraints. These constraints are modeled as the union of a finite number of convex polyhedra. ... -
Fracture behavior of quenched poly(lactic acid)
BME-PT (2011)The effect of a quenching treatment applied on heated cast sheet extruded films of two poly(lactic acid) (PLA) commercial grades, with different optical purities, was studied. The thermal and mechanical properties of the ... -
Discussion on Useless Active and Reactive Powers Contained in the IEEE Standard 1459
IEEE (2011)This paper deals with the useless active powers and the reactive powers included in the unbalance power (SU1), and in the nonfundamental effective apparent power (SeN) defined in IEEE Standard 1459. Only the fundamental ... -
PI and PID auto-tuning procedure based on simplified single parameter optimization
Elsevier (2011)In this paper a new auto-tuning algorithm for PI and PID controllers based on relay experiments is proposed to minimize the load disturbance integral error (IE) by maximizing the integral gain, subject to a desired phase ... -
Characterization and control of dimensionally similar systems
Elsevier (2011)When a model (i.e. experimental facility) and prototype (i.e. the real system) are dimensionally similar, then it is possible to extrapolate experimental results from model to prototype. In particular, in this article we ... -
Meaningful Resolution of the IEEE Std. 1459 unbalanced power
IEEE (2011)This letter present a new resolution of the IEEE Std. 1459 unbalanced power (SU1). The resolution is intended to achieve a better quantification of the power terms included in SU1 . The new definitions improve the ... -
Breakdown and evolution of the protective oxide scales of AISI 304 and AISI 316 stainless steels under high-temperature oxidation
