EFFICIENT AGGREGATION VIA ITERATIVE BLOCK-BASED ADAPTING SUPPORT-WEIGHTS

Local stereo matching algorithms based on adapting-weights aggregation produce excellent results compared to other lo- cal methods. In particular, they produce more accurate results near disparity edges. This improvement is obtained thanks to the fact that the support for each pixel is accurately deter- mined based on information such as colour or spatial distance. However, the computation of the support for each pixel results in computationally complex algorithms, especially when us- ing large aggregation windows. Iterative aggregation schemes are a potential alternative to using large windows. In this paper we propose a novel iterative approach for adapting- weights aggregation which produces better results and out- performs most previous adapting-weights methods

Ethical principles in occupational therapy intervention

For 2,500 years, the medical profession has created a body of ethical principles. Adapting to differeft historical and sociological circumstances, it has driven the practice of health professionals and constitutes a compilation of the rights and duties of doctors and patients.These principles represent the embryo of an emergening human science known as Bioethics. From the impulse of the scientific paradigm, a set of tasks and cares that were included in what was called charity started to be classified in a group of new proffesions devoted to the "methodical" care of patients and the underprivileged. Several new professions sprung up, including Occupational Therapy. From then on, the practice of the occupational therapist has remained protected by ethical principles that have traditionally monitored and driven the medical practice.This article first summarizes the historical evolution of the different ethical codes used by health professionals, emphasizing those aspects with a greater influence in the configuration of the ethical codes connected with occupational therapy.Secondly, we analyse the way occupational therapy has integrated the ethical principles of the medical practice in its own intervention. The main ethical guidelines used in the field are the ones proposed by the American Association of Occupational Therapy (AOTA), the World Federation of Occupational Therapists (WFOT), and the Council of Occupational Therapists for the European Countries (COTEC).Finally, we point out some of the difficulties and bioethcal challenges faced by occupational therapist

Effect of graphene oxide and fluorinated polymeric chains incorporated in a multilayered sol-gel nanocoating for the design of corrosion resistant and hydrophobic surfaces

In this work, it is proposed a multilayer sol-gel nanocoating onto aluminum alloys for the fabrication of new surfaces with a dual property of hydrophobicity and corrosion resistance. A study of two experimental variables such as number of dips and thermal treatment has been performed in order to have a better optimization of the nanocoatings with the desired corrosion resistance properties. A combination of a hybrid sol-gel matrix to host the corrosion inhibitor (graphene oxide) with a simple sol-gel matrix to provide hydrophobic properties (fluorinated polymeric chains) is presented. The effect of the thermal treatment is also analyzed for the formation of highly cross-linked sol-gel matrices with an improvement in the mechanical and hydrophobic properties. The surface and coating morphology have been determined by using atomic force microscopy, profilometry and scanning electron microscopy; whereas the hydrophobicity was determined by measurements of the water contact angle. Finally, the corrosion resistance of the sol-gel coatings has been determined using potentiodynamic polarization and electrochemical impedance spectroscopy. These results open up a new perspective for the design and implementation of novel coatings in applications of high performance.This work was supported by the Spanish Economy and Competitiveness Ministry–FEDERProyecto Retos TRA2013-48603-C4-1-R and by the Public University of Navarre collaboration research grants. The authors would like to express their gratitude to Nadetech Inc. for the tune-up of the robot used for the deposition of the nanocoatings.Peer Reviewe
