Repetition Rate of Partial Discharges in Low Voltage Cables
Authors: Cselkó Richárd
Published: October 2019

Diagnostic testing of low voltage cables by partial discharge measurement has several difficulties. One of them is that the cables are not designed to be partial discharge free at their test voltage. As partial discharge impulses may originate from numerous spots even in new cables, it is expected that impulses reach the termination with high repetition rate. The propagation of impulses in low voltage cables differs from the medium and high voltage cables; there is no lossy semiconducting layer or layers, but the cross section of the conductors are lower. The measurement method of partial discharges has to be adjusted to the discharge type and the propagation path as these determine the frequency content of the individual impulses, and the time resolution of the system has to be appropriate for the expected repetition rate. Measurements have been performed on various types of cables by different methods. Based on the results suggestions are given on the suitable measurement methods.

Authors: Obembe Olusola Michael , Kayode Joshua
Published: October 2019

A laboratory study was conducted to investigate the efficacy of powder and extract of C. alata on Callosobruchus maculatus Fab. damage in stored cowpea (Vigna unguiculata L.) seeds. The powder and the extract were evaluated on C. maculatus for mortality, oviposition and adult emergence effects. The long-term storage of the treated seeds was also investigated. All treatments recorded higher significant (p < 0.05) mortality than the experimental control. Highest mortality of 100 % was recorded in seeds treated with C. alata extract at the dosage level of 4.0 % v/w while highest mortality of 80.30 % was also recorded in seed treated with 4.0 g of C. alata powder. The powder and the extract significantly reduced oviposition and adult emergence in the treated seed. Adult emergence was totally suppressed in seeds treated with 3.0 % v/w and 4.0 % v/w. The powder and the extract also reduced infestation and subsequence damage of the treated seeds. No damage was recorded in seeds treated with 3.0 % v/w and 4.0 % v/w of the extract. The result obtained revealed that extract and powder of C. alata were effective in controlling C. maculatus and could be recommended as an alternative to synthetic insecticides.

Published: October 2019

The growth of crystalline Si (c-Si) via direct electron beam writing shows promise for fabricating Si nanomaterials due to its ultrahigh resolution. However, to increase the writing speed is a major obstacle, due to the lack of systematic experimental explorations of the growth process and mechanisms. This paper reports a systematic experimental investigation of the beam-induced formation of c-Si nanoparticles (NPs) from amorphous SiO
2
under a range of doses and temperatures by in situ transmission electron microscopy at the atomic scale. A three-orders-of-magnitude writing speed-up is identified under 80 keV irradiation at 600°C compared with 300 keV irradiation at room temperature. Detailed analysis reveals that the self-organization of c-Si NPs is driven by reduction of c-Si effective free energy under electron irradiation. This study provides new insights into the formation mechanisms of c-Si NPs during direct electron beam writing and suggests methods to improve the writing speed.
Terapia fetal
Authors: Antiñolo Gil Guillermo , García Díaz Lutgardo
Published: October 2019

La Realidad Virtual en Medicina Fetal permite enseñar los diversos aspectos de una cirugía novedosa que sólo es realizada en centros especializados. En este caso se muestra cómo transcurre una Fetoscopia Laser para ablación de anastomosis vasculares en un caso de Síndrome de Transfusión feto-fetal.

El Recurso creado ayuda a enseñar aspectos de extraordinaria relevancia de este procedimiento como es el acceso uterino o el seguimiento y control de los fetos mediante ecografía. Los vídeos obtenidos con el fetoscopio y la visión intrauterina son especialmente interesantes ya que dan una idea real de la orientación espacial y del escenario quirúrgico.

En concreto, este recurso consiste en una inmersión en vídeo 360 interactivo ( VR ), dividido en seis partes, correspondientes a la intervención quirúrgica sobre un feto.Todo el tiempo quirúrgico y su preparación se ofrece en vista general 360, incluyendo vídeos procedentes de :

1. La cámara del cirujano ( frente )
2. El Fetoscopio
3. El ecógrafo

La innovación técnica de este recurso reside en la integración de estas tres fuentes de vídeo plano y su sincronización, a voluntad del estudiante, en un vídeo panorámico que sirve de marco. El uso de la cámara subjetiva permite ponerse en el lugar del intervencionista para comprender mejor sus movimientos, mientras que la posibilidad de visión RV da al estudiante la sensación de encontrarse presente durante la intervención, posibilitando sentirse como parte del equipo. Se acompaña también de letreros interactivos didácticos que rotulan el instrumental y equipamiento del quirófano. Todo el recurso potencia su función didáctica con la locución explicativa de la intervención realizada por el propio cirujano intervencionista, el Dr. Lutgardo García Díaz.

El Recurso puede experimentarse directamente con el navegador en modo 360º tanto en equipos de escritorio como con dispositivos móviles. No obstante, es altamente recomendable una mejor experiencia inmersiva, la cual puede obtenerse ayudándose de unas gafas de Realidad Virtual con las que pueda conectarse mediante Mozilla Firefox ( Oculus, HTC Vive, Daydream o Cardboard ).

Published: October 2019

En esta tesis se ha estudiado la modificación de la superficie de nanopartículas de oro con el objetivo final de contribuir al desarrollo de un sensor fluorescente fotomodulable a escala nanométrica. Estos sensores están formados por dos partes esenciales: un centro metálico y una coraza orgánica. La nanopartícula de Au en el centro tiene un tamaño menor a 4 nm, sobre la que se ensambla un polímero antifílico. Este último fue modificado con moléculas fluorescentes y fotocrómicas que actúan como sonda y fotomodulador, respectivamente. Estas dos partes, nanopartículas y polímero, se prepararon, purificaron y caracterizaron, para luego ser ensamblados, formándose así una sonda fluorescente fotomodulable.

Published: October 2019

La presente tesis aborda el juego, cuerpos y movimiento en la formación de profesores de niños, teniendo como objetivos del estudio analizar la concepción de niños, juego, cuerpo y movimiento presente en el curso de Pedagogía – UEPG; verificar las relaciones existentes entre las concepciones de niños, cuerpo y movimiento y los abordajes sobre el juego tratadas en el curso de formación de profesores; identificar las concepciones de niños, cuerpo y movimiento y su articulación con el juego observadas y/o vividas en la práctica pedagógica durante las Prácticas Docentes Supervisadas en educación infantil; comprender en qué medida la formación inicial puede contribuir para una práctica pedagógica comprometida con las especificidades del juego. Con este propósito, examinamos la estructura curricular del curso investigado con el fin de identificar los tiempos y espacios destinados a los estudios sobre el niño/infancia, el juego, cuerpo y movimiento, enlazado con la escucha de los académicos sobre sus experiencias durante el proceso formativo y el análisis de los diarios de a bordo de la asignatura Prácticas Docentes Supervisadas en Educación Infantil, debido al potencial reflexivo y cuestionador y revelador de estos textos. Tales análisis son tejidos apoyados en referencias que nos ayudan a pensar la ampliación de la formación de profesores, las especificidades de la formación de profesores de Educación Infantil, la potencia del juego, cuerpo y movimiento en los niños. Destacamos como contribuciones de este estudio el reconocimiento del juego, cuerpo y movimiento como medio de expresión y de construcción de conocimientos sobre los niños, siendo reconocido por las miradas atentas y voces indignadas de los estudiantes de Pedagogía, al depararse con el cotidiano de las instituciones de Educación Infantil y la capacidad de extrañamiento, cuestionamiento y reflexión sobre lo vivido en la institución educativa y en su proceso formativo, debido al escaso abordaje de temas relacionados con los niños/infancias y educación infantil. Como posible continuación de este estudio, destacamos la necesidad de que los niños, las infancias, el juego, cuerpo y movimiento, así como todas las otras especificidades del ser profesor de Educación Infantil, ingresen a los cursos de pedagogía, en un movimiento de reflexión, indagación de los modelos impuestos, de valorización de la práctica, de la experiencia y de la sensibilidad.
Entrelazamiento en sistemas de espines y en modelos cuánticos de tiempo
Authors:   , Boette Alan Pablo
Published: October 2019

En el presente trabajo de Tesis se examina el entrelazamiento cuántico y su rol en sistemas de espines y en modelos cuánticos de tiempo. En primer lugar, se aborda el problema de la determinación del entrelazamiento cuántico en sistemas de espines interactuantes por medio de aproximaciones de campo medio no convencionales. Un primer objetivo fue lograr una descripción física simple pero consistente de sistemas de espines en los que la aproximación de campo medio convencional (basada en espines independientes) no logra proporcionar siquiera una descripción básica razonable del estado fundamental, tal como sucede en sistemas dimerizados. En la segunda parte, se considera la aplicación del concepto de entrelazamiento al propio problema de la definición de tiempo y de la cuantificación de la evolución. Se presenta y analiza un modelo cuántico de evolución discreta basado en correlaciones cuánticas entre un sistema dado y un sistema reloj de referencia, logrando incorporar la noción de tiempo dentro de la teoría cuántica como consecuencia del entrelazamiento entre dos partes de un estado en principio atemporal. Estas dos partes se encuentran vinculadas, ya que los estados de cadenas de espines dimerizados se pueden considerar, gracias al modelo discreto de tiempo propuesto, como relojes cuánticos de espines. Finalmente, se presenta un esquema experimental de fotón individual y un modulador espacial para simular un estado historia sistema-tiempo, realizado en colaboración con el Laboratorio de Procesado de Imágenes.
La violencia (escolar) en cuestión
Authors:   , Patierno Nicolás
Published: October 2019

La tesis tiene como objetivo sistematizar y analizar las diversas manifestaciones que, de acuerdo al relato de alumnos y educadores, suelen considerarse “violentas”. Esta tarea fue llevada a cabo en tres escuelas públicas secundarias de la ciudad de La Plata, a través de una investigación de tipo cualitativa sustentada en la revisión de fuentes documentales y en la realización de entrevistas a informantes considerados claves. La hipótesis que orienta esta tesis presupone que los actos que tanto educadores como alumnos suelen identificar como “violentos” se producen, fundamentalmente, a causa de dos fenómenos: una reconfiguración de la autoridad y un debilitamiento del lenguaje; procesos que, si bien exceden lo estrictamente escolar, dificultan considerablemente la constitución de lazos sociales en su interior. El efecto resultante de estos movimientos es la autorregulación que se espera de y en definitiva se impone a los propios jóvenes, lo que deriva en la conformación de grupos –en cierto modo clánicos o tiránicos–, en los que la violencia, entendida como una manifestación “más física” que revela la escasez de recursos simbólicos, se impone como un medio de relación naturalizado, habitual, no identificable como falta o trasgresión.
Anatomía y morfología funcional del esqueleto de pingüinos (Aves, Sphenisciformes) actuales, aplicaciones en los fósiles
Authors:   , Haidr Nadia Soledad
Published: October 2019

Los pingüinos (Aves, Sphenisciformes) poseen una serie de modificaciones anatómicas, fisiológicas, y comportamentales relacionadas con el buceo. Su abundante registro fósil se remonta al Paleoceno, y cuenta con especímenes fósiles en excelente estado de conservación como por ejemplo Madrynornis mirandus (Mioceno Medio tardío de Patagonia), el cual resulta un interesante caso de estudio por su cercanía filogenética con las especies actuales y porque presenta un esqueleto casi completo. El estudio morfológico de formas actuales, de las cuales se posee información sobre el tipo de presa y buceo, sirve de base para obtener modelos anatómicos que podamos relacionar con el hábito de vida que poseen los pingüinos. Esto nos permite inferir y proponer el posible hábito que la especie fósil habría tenido. En la presente tesis se diseccionaron un gran número de pingüinos de diferentes especies, para estudiar en detalle la musculatura del cráneo y aquella relacionada con el movimiento del ala. También se tomaron fotos en diferentes vistas del cráneo, mandíbula, húmero, coracoides, y esternón, de un gran número de especímenes, para realizar análisis de morfometría geométrica. Esto nos permitió llevar a cabo análisis exploratorios de la variación de forma que incluyeron un gran número de especies actuales, estudiar si existen diferencias morfológicas entre las categorías dietarias asignadas a las especies actuales, determinar de qué manera varía la morfología entre categorías, y por último estudiar si los cambios morfológicos entre estructuras diferentes (como por ejemplo entre el cráneo y el húmero) se correlacionan. Además se re-describió a Madrynornis mirandus, el espécimen fósil bajo estudio, y se lo incluyó en los análisis. Resultó que las categorías alimentarias pre-asignadas presentan diferencias morfológicas significativas para todas las estructuras analizadas. Se determinó además, que existe una moderada correlación en la variación de forma entre estructuras tales como el cráneo y el húmero, y que el cráneo-pico varían como una estructura integrada. En particular, para Madrynornis mirandus se obtuvieron diferentes clasificaciones en categorías dietarias dependiendo del hueso analizado, pero mayoritariamente fue clasificado como piscívoro. Los resultados demuestran la factibilidad y la utilidad de la aplicación de estos modelos de modo predictivo para establecer la dieta y los hábitos tróficos en los pingüinos fósiles, a partir de los elementos del ala, la cintura pectoral, y el cráneo. Inferimos que Madrynornis mirandus habría sido un pingüino piscívoro, aunque oportunista y con una posible tendencia a la captura de presas pequeñas como crustáceos.

In this research we are discussing the physicochemical characteristics of sweet diesel after desulphurization alone and also these characteristics are tested with the adding of high purity HPLC ethanol (99.9%). Those fuel properties of ethanol blended with diesel were experimentally determined to find their stability and to increase their properties and efficiency in the diesel engines. First we made 4 blends of diesel with ethanol and the fifth sample was pure diesel. The samples were 0% ethanol and 100 % diesel, the second sample was 5% ethanol and 95 % diesel, the third sample was 10 % ethanol and 90% diesel, the fourth sample was 15 % ethanol and 85 % diesel and the fifth and last sample was 20 % ethanol and 80 % diesel. The physicochemical characteristics of the diesel ethanol blends were determined by the following experiments (cetane number, ASTM distillation, flash point, pour point, kinematic viscosity, ASTM density and calorific value).the aim of this research is to obtain an optimum blend of diesel ethanol fuel to help in improving the diesel engines and to lower the emission in the engine and the exhaust gases produced in the engines. This blend we obtained in this research was done to meet the EURO 5 standards and regulations, also to help to make an economic improvement in the industry of diesel in Egypt and in the world. The diesel ethanol blend was to be an effective fuel as we will see in the different tests and ASTM methods. Many tests and experiments done during this research project and the obtained results were similar to the EURO 5 standard emissions regulation.

This article presents a multihop spatial multiplexing cooperative MIMO (SM-CMIMO) transmission scheme. The SM-CMIMO scheme employs a novel configuration on MIMO system which works in a cooperative manner, to achieve a least energy consuming path, with reduced rate of bit error and higher data rate. In this approach, list of relay nodes located in equal distance at any route towards destination selected. The source selects a set of relay nodes and cooperative nodes to frame a cooperative MIMO System. The cooperative nodes are selected using NSA (Node Selection Algorithm) with no channel state, bit error rate and data rate constraints. Each hop is evaluated for suitable replacement with V-MIMO configurations. To reduce the depletion of energy at MIMO cooperative network, at the middle of these hops, relay nodes are selected and evaluated for possible replacement of long-hop with two smaller MIMO transmission hops. We show that proposed SM-CMIMO transmission offers significant energy efficiency improvement compared with SISO transmission. The performance of the system degrades indirectly with the channel correlation.

Multispectral image compression plays a vital role in remote sensing through satellites. Satellite images are more powerful approach to study the space information and research the geographical nature of the earth. Satellite images contains the huge amount of data and it requires more bandwidth for transmission and more memory for storage. Multispectral image compression reduces the size of the multispectral data and makes it easy for storage and transmission to the earth station form the satellite. The image is compressed by reducing the irrelevant and redundant part of data. This paper presents FPGA implementation of multispectral image compression using Dual Tree Complex Wavelet Transform (DTCWT) and Arithmetic Coding. This compression algorithm is implemented and simulated using MATLAB and XILINX ISE14.5 simulator. The FPGA Spartan -6 architecture is used to implement the algorithm. The proposed method gives better result in PSNR and MSE ratio as compared to DWT.

Using sensors in healthcare can greatly improve the quality of life, especially for elderly patients. The data from the sensors of the patients is constantly monitored for abnormalities at a server. Whenever this data crosses a threshold value, the information is notified to the corresponding doctor. The doctor can then take the necessary action. However an inspection of historical data has shown that some conditions of patients have cyclic patterns and the medications are often repeated. The proposed system is designed to assist the doctor in diagnosis by retrieving those patterns. We have compared the times taken for receiving responses from the two different systems and a significant amount of improvement was noticed. We have introduced a Dynamic Context Aware Technique (DCAT) which can improve the quality of 24 hour monitoring patient. This paper presents the design and implementation of a system based on DCAT using SAMSUNG GEAR S (Heart rate monitor sensor.The backend remote centralized computation and data storage can decreases the workload of the remote health care provider by avoiding of sending the identical and similar cases data to the doctors. This improves the processing speed and also gives solutions in case of the unavailability of doctors in some cases. Experimental results based on real datasets show that our system is highly efficient and scalable to a long time monitoring patients.

This mathematically designed model explores the facts about the velocity of blood flow in an inclined artery as well as in the presence of a magnetic field. This model conjointly reveals regarding core velocity, shear stress on the wall of artery and volumetric rate of flow under constricted condition. Here we are describing blood as Herschel-Bulkley fluid through an inclined artery which is multiple stenosed at equally spaced and distanced. By using appropriate boundary conditions, analytic expressions for these flow characteristics are administered. The results are shown numerically and diagrammatically still as compared with the prevailing results. This data could also be valuable within the progress of the most recent diagnosing tools for solidifying hardening of the arteries.

The images captured by SAR and sonar are blurred and corrupted more by speckle noise and also other types of noise like Gaussian noise and salt & pepper noise. Denoising all types of noises to get perfect image is a vital challenge, earlier works on the same mode addressed with one filter for one noise, there is no one common or unified filter which can denoise all types of noise. Therefore in this paper, we have designed a filter which not only removes speckle noise, but also combination of other noises. Here IUNR (Intelligent Unified Noise Reduction) algorithm is proposed which is based on neural network called adaptive radial basis function acts as a unified filter for Denoising. Proposed method needs a single noisy image to train the adaptive radial basis function neural network to learn the correction of the noisy image. The Gaussian kernel function is applied to reconstruct the local disturbance appeared because of the noise. The proposed adaptive radial basis function network is compared with the fixed form which has fixed spread and the center value of kernel function. This method can correct the image suffered from different varieties of noises like speckle noise, salt & pepper noise and Gaussian noise separately or combination of noise. Various standard test images are considered for test purpose with different levels of noise density and performance of proposed algorithm is compared with adaptive wiener filter.

Current web applications are “closed” web applications. Such applications do not support integration and interoperability amongst them. Semantic web stack, however provides for languages and tools that help in achieving interoperability and integration amongst various web applications. Web applications developed nowadays are distributed and interoperable. Semantic web stack enables the designers to embed semantic web descriptions using Ontologies [1]. Ontologies provide a shared understanding of a given realm that can be disseminated amongst people and across application systems [2]. In addition to building semantic web systems that are interoperable and distributed there is also a need to make these semantically enabled systems trustworthy. Various work has been done till date regarding the trust and various mathematical models have been proposed t regarding the same. In this paper we are trying to address the issue of provenance using PROV-DM data model. The Provenance architecture has been proposed by the Provenance working group. We have tried to implement the data model in a university Ontology and have tried to show how provenance can be embedded to Semantically enabled University People Program Ontology.

In recent times, Direction of Arrival (DOA) Estimation study earns attention in array signal processing and it develops rapidly in several application such as sonar, radar, communication, biomedicine and seismology measurements. The self adaption and spatial spectrum are the broad research area in array processing. The spatial spectrum estimation focused on the signal distribution in the space is received from all direction to receiver. To maintain accuracy in DOA estimation for the antenna array the basic knowledge is required for main beam, and side lobes pattern must be small to suppress signal from other direction. This paper discussed the overview of the Direction of Arrival (DOA) estimation based on classical Sum and delay beamformer, Minimum Variance Distortionless Response (MVDR) technique, Min Norm technique and Multiple Signal Classification(MUSIC) by using the spatial spectrum parameters.
