Correction system for polyphonic piano recordings

M.I. Martin-Erdozain, I. Barbancho, A. Rosa-Pujazon, A.M. Barbancho, "Correction system for polyphonic piano recordings", XXVIII Simposium Nacional de la Unión Científica Internacional de Radio, Santiago de Compostela, España, 2013n this paper, a support tool for piano rehearsal is presented. The system analyses a given piano polyphonic recording to find the times, pitch and duration of the notes and figures played, taking into account the possibility of playing more than one note simultaneously as well as covering the whole piano frequency range. In order to do so, the system uses an onset detection algorithm to segment the input signal into partitions which are then analysed in the time and frequency domains. Then, the system correlates the data extracted from the partitions with the score of the original piece, identifying the positions and type of the mistakes performed by the user, and providing her/him with the corresponding feedback. The experiments conducted showed that the application is capable of analysing a given recording and indicate the musician the mistakes made.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03-02 and by the Ministerio de Industria, Turismo y Comercio under Project No. TSI-090100-2011-25

Conducting a virtual ensemble with a kinect device

This paper presents a gesture-based interaction technique for the implementation of an orchestra conductor and a virtual ensemble, using a 3D camera-based sensor to capture user’s gestures. In particular, a human-computer interface has been developed to recognize conducting gestures using a Microsoft Kinect device. The system allows the conductor to control both the tempo in the piece played as well as the dynamics of each instrument set independently. In order to modify the tempo in the playback, a time-frequency processing-based algorithmis used. Finally, an experiment was conducted to assess user’s opinion of the system as well as experimentally confirm if the features in the system were effectively improving user experience or not.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03-02 and Project No. IPT-2011-0885-430000 and by the Junta de Andalucia under Project No. P11-TIC-7154.

Virtual Conductor for String Quartet Practice

This paper presents a system that emulates an ensemble conductor for string quartets. This application has been developed as a support tool for individual and group practice, so that users of any age range can use it to further hone their skills, both for regular musicians and students alike. The virtual conductor designed can offer similar indications to those given by a real ensemble conductor to potential users regarding beat times, dynamics, etc. The application developed allows the user to rehearse his/her performance without the need of having an actual conductor present, and also gives access to additional tools to further support the learning/practice process, such as a tuner or a melody evaluator. The system developed also allows for both solo practice and group practice. A set of tests were conducted to check the usefulness of the application as a practice support tool. A group of musicians from the Chamber Orchestra of Malaga including an ensemble conductor tested the system, and reported to have found it a very useful tool within an educational environment and that it helps to address the lack of this kind of educational tools in a self-learning environment.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03- 02 and Project No. IPT-2011-0885-430000 and by the Ministerio de Industria, Turismo y Comercio under Project No. TSI-090100-2011-25

Parenting Styles and Internet Use

The Internet has become the most popular way for young people to communicate with one another. Recent data indicate that 95% of students have Internet access. This study examined the links between Internet use and the parenting styles that shape parent-child interactions. Empirical analysis showed that Internet use accounts for the majority of adolescents' leisure time. The neglecting parenting style has the strongest relationship with addictive Internet use by adolescent girls and boys. For boys, addictive Internet use is also related to a combination of different parenting styles resulting from inconsistencies and contradictions between parents

Evaluation of seven tumour markers in pleural fluid for the diagnosis of malignant effusions

Carcinoembryonic antigen (CEA), carbohydrate antigens 15–3, 19–9 and 72–4 (CA 15–3, CA 19–9 and CA 72–4), cytokeratin 19 fragments (CYFRA 21–1), neuron-specific enolase (NSE) and squamous cell carcinoma antigen (SCC) were evaluated in pleural fluid for the diagnosis of malignant effusions. With a specificity of 99%, determined in a series of 121 benign effusions, the best individual diagnostic sensitivities in the whole series of 215 malignant effusions or in the subgroup of adenocarcinomas were observed with CEA, CA 15–3 and CA 72–4. As expected, a high sensitivity was obtained with SCC in squamous cell carcinomas and with NSE in small-cell lung carcinomas. CYFRA and/or CA 15–3 were frequently increased in mesotheliomas. Discriminant analysis showed that the optimal combination for diagnosis of non-lymphomatous malignant effusions was CEA + CA 15–3 + CYFRA + NSE: sensitivity of 94.4% with an overall specificity of 95%. In malignant effusions with a negative cytology, 83.9% were diagnosed using this association. The association CYFRA + NSE + SCC was able to discriminate adenocarcinomas from small-cell lung cancers. Regarding their sensitivity and their complementarity, CEA, CA 15–3, CYFRA 21–1, NSE and SCC appear to be very useful to improve the diagnosis of malignant pleural effusions. © 1999 Cancer Research Campaig

Efectividad de un protocolo de atención asociando osteopatía estructural y fisioterapia funcional en los lactantes de menos de 4 meses con plagiocefalia funcional. Proyecto de estudio: un ensayo clínico controlado

Curs 2018-2019Verdadero problema de salud pública por su incidencia en los recién nacidos, la plagiocefalia posicional es una patología caracterizada por una deformidad craneal e por sus consecuencias estructurales e funcionales hoy bien identificadas, necesitando una atención específica e adaptada. Apoyándonos sobre numerosos estudios abriendo la oportunidad de considerar la plagiocefalia posicional desde un nuevo punto de vista más global e funcional, nuestro estudio cuestiona la efectividad de un protocolo de atención copleando osteopatía estructural y fisioterapia funcional en los lactantes de menos de 4 meses con plagiocefalia calificada de funcional. Esencialmente realizada en una consulta privada de Montpellier (France) con la participación de un pediatra neurólogo, dos fisioterapeutas e un osteópata, nuestro proyecto se apoyara sobre un estudio experimental de tipo ensayo clínico controlado. Se cuantificara la efectividad de nuestro protocolo experimental sobre 40 lactantes con plagiocefalia posicional repartidos en 2 grupos, gracia a la medida de los parámetros objetivos de deformación craneal, a la valoración de la función motora gruesa e del nivel de desarrollo motor, e al análisis de los datos obtenidos por las herramientas SPPS e prueba T de Student. Nuestro protocolo sufrirá ineluctablemente de limitaciones inherentes al tamaño de estudio cuestionando la posibilidad de extrapolar los resultados, a la secuencia temporal elegida e al tema del factor tiempo e por fin, a la reproductibilidad de nuestro tratamiento por parte examinador dependiente.Real public health problem due to its incidence in newborns, positional plagiocephaly is a pathology characterized by a cranial deformity and structural and functional consequences today well identified, requiring specific and adapted attention. Based on numerous studies opening the opportunity to consider positional plagiocephaly from a new, more global and functional point of view, our study questions the effectiveness of an attention protocol combining structural osteopathy and functional physiotherapy in infants less than 4 months old with “functional” plagiocephaly. Essentially carried out in a private practice in Montpellier (France) with the participation of a pediatric neurologist, two physiotherapists and an osteopath, our project will be based on an experimental study of a controlled clinical trial type. We will quantify the effectiveness of our experimental protocol on 40 infants with positional plagiocephaly divided into 2 groups, thanks to the measurement of the objective parameters of cranial deformation, the assessment of gross motor function and the level of motor development, and the analysis of the data obtained by the SPPS tools and Student's T test. Our protocol will suffer ineluctably from limitations inherent to the size of the study, questioning the possibility of extrapolating the results, to the chosen temporal sequence and to the issue of the time factor and, finally, to the reproducibility of our treatment “dependent examiner”
