Inducción de mecanismos de la respuesta innata por péptidos de gliadinas en un modelo de enteropatía experimental
Authors:   , Gómez Castro María Florencia
Published: October 2019

El gluten es una mezcla heterogénea de proteínas, principalmente gliadinas y gluteninas, que al ser ingerido es degradado por enzimas del tracto gastrointestinal. Algunos péptidos derivados de gluten son resistentes a la degradación enzimática y pueden encontrarse en el lumen intestinal y desencadenar respuestas inmunes tanto adaptativas, como innatas. Entre los péptidos derivados de gliadina resistentes a la degradación se encuentra el péptido p31-43, que no se une a moléculas de MHC de clase II y en consecuencia no es capaz de inducir una respuesta adaptativa específica. Existen numerosos estudios in vitro acerca de la toxicidad de p31-43, sin embargo, en la actualidad se desconoce su receptor celular y no se han descripto en profundidad sus efectos in vivo. En el presente trabajo de tesis se utilizó un modelo murino de enteropatía inducida mediante la administración intraluminal de p31-43, así como también se desarrolló un modelo de administración de p31-43 por vía intragástrica, de modo de estudiar mecanismos de la respuesta innata en intestino delgado. En este modelo intentamos reproducir algunos aspectos de la patogenia de enfermedad celíaca (EC). Esta es una enteropatía crónica que se desencadena en individuos genéticamente predispuestos ante el consumo de proteínas de gluten y bajo la influencia de otros factores ambientales. EC tiene una prevalencia global del 1 % y se caracteriza por la presencia de atrofia vellositaria e hiperplasia de criptas en intestino delgado, así como también, por un marcado incremento en el infiltrado linfocitario en lamina propria y en el epitelio intestinal. En este trabajo de tesis se observó que la enteropatía murina inducida, es específica de la secuencia de aminoácidos de p31-43 y dependiente de la vía de IFN tipo I. Además, corroboramos que p31-43 induce apoptosis tanto in vitro, como in vivo. Por otro lado, se caracterizó las propiedades estructurales y de agregación de p31-VI 43. Se observó que posee una estructura del tipo poliprolina II y que forma agregados proteicos en solución estables a pHs intestinales (3-8), cuyo tamaño se incrementa con la concentración y evolucionan en el tiempo a estructuras más complejas. Finalmente, observamos que las moléculas de NLRP3 y Caspasa-1 estaban implicadas en el daño. Por lo que consideramos que los agregados de p31-43 podrían ser sensados por el inflamasoma NLRP3 y ejercer efectos inflamatorios vía Caspasa-1.

Capacitar para el cambio conceptual y la innovación. Dispositivos y estrategias didácticas para la formación de los profesores de Ciencias Naturales en ejercicio
Authors:   , Stigliano Daniel Ernesto
Published: October 2019

La tesis toma como punto de partida dos experiencias de capacitación de profesores de ciencias naturales en ejercicio, situadas en el contexto de la institución escolar, en el marco de una investigación dirigida por el autor de esta tesis y financiada por el Programa “Conocer para incidir sobre las prácticas pedagógicas”, Instituto Nacional de Formación Docente (2010-2011). La metodología se centró en un taller de cambio conceptual que se implementó a los docentes de la muestra bajo la denominación: Taller de Diseño de Estrategias a partir de la Teoría de las Inteligencias Múltiples. El mismo se diseñó alrededor de diferentes actividades tendientes a generar un espacio movilizador y pertinente para la modificación de las creencias que obstaculizan los procesos de cambio e innovación en la enseñanza. Para ello, se desarrolló una mirada crítica de la realidad actual de la escuela secundaria y las particularidades de la carrera docente en el sistema educativo argentino. Con este propósito, se seleccionaron deliberadamente cuatro dispositivos didácticos de perspectiva constructivista tales como la narración autobiográfica, el trabajo en grupos informales de aprendizaje cooperativo, las comunidades de diálogo y encuentro y los ejercicios de metacognición que facilitan, si se implementan adecuadamente, el desarrollo armónico de diferentes procesos cognitivos. A partir de la discusión de los resultados de la experiencia, se proponen formatos alternativos para la capacitación docente continua, algunos apuntes para la mejora de la carrera docente en nuestro país y algunas iniciativas de capacitación en servicio no tradicionales.
Tras las huellas de la igualdad
Authors:   , Pinos Montenegro Judith Elizabeth
Published: October 2019

Esta tesis está atravesada por las categorías educación, igualdad e interculturalidad, aspectos de interés de las Ciencias Sociales, principalmente de la Sociología y de la Antropología. Reflexionar sobre la igualdad en educación nos lleva a analizar los proyectos que cada sociedad plasma a través de sus políticas públicas, así como las perspectivas y las recepciones por parte de los agentes escolares. La presente tesis se propuso responder a la pregunta ¿Cómo es/son interpretada(s), apropiada(s) y aplicada(s) la(s) política (s) pública (s) de igualdad en educación, por agentes escolares de una institución escolar, que viene de una estructura pedagógica segregada para la enseñanza bilingüe del kichwa y del español? Entendemos que las interpretaciones, las apropiaciones y las aplicaciones de las políticas públicas de igualdad en educación, se producen en contextos específicos. Pero, lejos de ser asuntos individuales, son resultados de un tejido de experiencias pasadas, presentes y de los anhelos futuros que los grupos tienen en el marco de las culturas que les atraviesan. Optamos en esta tesis por la metáfora “huella”, entendida como un recurso analítico que permite entender tanto las dimensiones subjetivas, como contextuales e históricas, que abrazan las particularidades y los elementos más generales que circulan en los entornos socioculturales. Identificar las huellas de la igualdad educación supuso tanto un trabajo de análisis documental, como un acercamiento vivencial al contexto escolar, para detectar cómo los agentes escolares entran en diálogo con los límites y posibilidades de las políticas públicas para la educación. La escuela es un entorno en el que circulan estudiantes, docentes y familias, por eso esta investigación recuperó sus voces a través de un trabajo cualitativo en una institución de la Educación General Básica, del Sistema Intercultural Bilingüe, ubicada en Ecuador, en la Provincia de Tungurahua, en la ciudad de Ambato, donde el carácter bilingüe está dado por la enseñanza en kichwa y español. El desarrollo de este documento se sustenta en un ir y venir entre las voces de los agentes, el contexto bilingüe, el carácter intercultural y los marcos establecidos por las políticas públicas para la igualdad en educación, comprendidas entre los años 2007 a 2017.
La escritura expresiva en la lengua materna como estrategia para aliviar el estrés antes de la evaluación formal en una lengua extranjera: Desafíos y percepciones
Authors:   , Argudo Serrano Juanita Catalina
Published: October 2019

La utilización de la escritura expresiva para aliviar los síntomas físicos y emocionales ha tomado fuerza en los últimos años. Así también, se ha utilizado esta estrategia para aplacar el estrés académico en diferentes grupos de estudiantes antes de ser sometidos a distintos tipos de evaluación; No obstante, existe poca evidencia de la utilización de esta estrategia en la lengua materna, para aliviar el estrés en estudiantes de una lengua extranjera. El objetivo esta investigación es estudiar si la escritura expresiva en la lengua materna puede reducir el estrés y mejorar el rendimiento académico en dos tipos de estudiantes, los de inglés como lengua extranjera y los de la carrera de Lengua Inglesa; además de analizar sus percepciones sobre la utilización de esta estrategia Doscientos nueve estudiantes de la Universidad de Cuenca, tres cursos de pregrado de la carrera de Lengua Inglesa, un curso de Maestría de Lingüística Aplicada a la Enseñanza de Inglés como Lengua Extranjera y cuatro cursos del Instituto Universitario Lenguas en los cuales se imparte Inglés como lengua extranjera fueron parte de este estudio. En un inicio se aplicó una adaptación al español del cuestionario “Pennebaker Inventory of Limbic Languidness” (PILL) desarrollado por el Dr. Pennebaker. Posteriormente, se pidió a los participantes que escribieran durante diez minutos sobre alguna experiencia específica de estrés académico de su pasado, antes de ser sometidos a una evaluación formal, Además, inmediatamente después de la evaluación, se administró una encuesta sobre las percepciones de los participantes en cuanto a la utilización de la escritura expresiva. Finalmente, grupos focales con participantes seleccionados, se llevaron a cabo. Los resultados revelaron que existe un alivio paulatino del estrés académico en los participantes, no así una mejora en el rendimiento académico. A pesar de éstos resultados, los participantes manifiestan sentirse beneficiados con la utilización de esta estrategia, por lo tanto, sería necesario seguir investigando este tema.

Conflicting Health-Related Scientific Evidence in News Reports: Effects of Hedging and Presentation Format on Perceived Issue Uncertainty and Scientists’ and Journalists’ Credibility
Authors: Zhang Hui
Published: October 2019

Introduction: This study examined effects of two journalistic practices in reporting conflicting scientific evidence, hedging and presentation format, on scientists’ and journalists’ credibility and issue uncertainty. Methods: An online experiment was conducted using students from a western U.S. university. Hedging was manipulated as reporting methodological limitations versus not reporting the limitations in news articles covering the conflict. Presentation format was manipulated as using a single news article to report both sides of the conflict versus using double articles with one side of the conflict in one article and the other side in the other article. Results: The study found that perceived issue uncertainty was higher in hedged news articles than that in non-hedged articles; presentation format did not affect people’s perceived issue uncertainty. For scientists’ credibility (both competence and trustworthiness), this study found that it was lower in the single-article format than that in the double-article format; for journalists’ credibility, this study found that journalists’ trustworthiness in the two formats did not vary, but their competence was lower in the double-article format than that in the single-article format. Conclusion: This study contributes to the field of science and health communication by examining effects of presentation format used in communicating conflicting health-related scientific evidence and by examining effects of communicating scientific limitations in a context where conflicting evidence exists. Keywords: conflicting scientific evidence, hedging, presentation format, scientists’ credibility, journalists’ credibility

Gasoline produced in Egypt is a low-grade gasoline that contains high concentration of harmful components that are having a toll on our environment. In addition, those pollutants cause countless diseases and deaths annually to the Egyptian population. This paper targets two main sectors in the production of commercial gasoline. The improvement engine efficiency through the upgrading of octane number is first experimented by using a blendstock that ranges from gasoline fractions and Isomerates. An optimum was then chosen depending on the results obtained from different tests. Through those experiments, it was determined which samples obeyed the EU regulation for transportation emissions. Having an excellent gasoline with a high octane number but produced large quantities of harmful emissions was unacceptable. This leads to the section aim of this research, which was to produce an environmental gasoline. This meant that once the gasoline sample is combusted, it should produce limited amounts of emissions such as 1% benzene since benzene is carcinogenic. A sample with euro 3 specification was produced and showed excellent gasoline properties such as an RON value of around 95 without the use of octane enhancers. A second sample showed better results satisfied euro 5 regulations and produced an even higher octane number than the euro 3 sample. This sample was the optimum environmental ETBE-gasoline high octane number blend. By understanding the composition of those samples, maximum yield of commercial gasoline could be produced. This would also lead to the reduction of pollutants in the environment. Completing this task with successful results means that this environmental high octane number gasoline could be produced and used in Egypt. Such blends should be produced on a large scale by exercising euro 3 and/or 5 regulations.

Economic Analysis for Energy Efficient Reactive Distillation
Authors:   Manipal Academy of Higher Education (MAHE), Dubai, UAE., Sakhre Vandana
Published: October 2019

Complex chemical reactions and downstream processing can be performed in reactive distillation column to overcome with equilibrium limitations and to make it an economical process. An existing reactive distillation unit is costly to modify due its complex configuration and existing limitations of structure, space area, etc. Modifying an existing plant is a tedious task and more complex than a new process. Thus, to modify the existing operating conditions and input design variables it is necessary to verify by applying the same in real plant condition. This is done using revamping based on rigorous simulation and optimization in Aspen Plus process simulator. The main form of energy generator used in a distillation column is reboiler which directly affects the utilities such as cooling water, electricity and steam. Therefore, optimizing this reboiler duty to reduce energy losses is done using optimization model analysis tool of Aspen Plus. This reduction of energy demands diminishes the operating cost as per the reduction in utility cost. Now this reduction in operating cost is evaluated corresponding to the optimized reflux ratio and number of plates as obtained using sensitivity analysis tool of Aspen Plus.

Recommendation algorithms play a quintessential role in development of E-commerce recommendation system, Where in Collaborative filtering algorithm is a major contributor for most recommendation systems since they are a flavor of KNN algorithm specifically tailored for E-commerce Web Applications, the main advantages of using CF algorithms are they are efficient in capturing collective experiences and behavior of e-commerce customers in real time, But it is noted that , this results in the phenomenon of Mathew effect, Wherein only popular products are listed into the recommendation list and lesser popular items tend to become even more scarce. Hence this results in products which are already familiar to users being discovered redundantly, thus potential discovery of niche and new items in the e-commerce application is compromised. To address this issue , this paper throws light on user behavior on the online shopping platform , accordingly a novel selectivity based collaborative filtering algorithm is proposed with innovator products that can recommend niche items but less popular products to users by introducing the concept of collaborative filtering with consumer influencing capability. Specifically, innovator products are a special subset of products which are less popular/ have received less traction from users but are genuinely of higher quality, therefore, these aforementioned products can be captured in the recommendation list via innovator-recognition table, achieving the balance between popularity and practicability for the user

Due to the increase in demand of electric energy, people are shifting towards renewable energy resources. Among the various renewable sources, solar power is growing at a faster rate due to its abundant availability. Solar panel characteristics show that the output power from the panel peaks only at one operating point. For extracting maximum power from the panel, tracking of the operating point has to be done continuously by a control algorithm. In this work, a solar system connected to the grid is considered, where there is a necessity of synchronizing the solar inverter with the grid apart from MPPT. Hysteresis current control is implemented in the inverter for synchronization and for tracking the maximum power, perturb and observe algorithm is applied. Grid connected PV systems are used in main cities by domestic and industrial consumers, where the excess power can be sold to the utility. Simulation of the grid connected PV system is done in Simulink and the results are presented.

Edge detection is long-established in computer perception approach such as object detection, shape matching, medical image classification etc. For this reason many edge detectors like, Sobel, Robert, Prewitt, Canny etc. has been progressed to increase the effectiveness of the edge pixels. All these approaches work fine on images having minimum variation in intensity. Therefore, a new objective function based distinct particle swarm optimization (DPSO) is proposed in this paper to identify unbroken edges in an image. The conventional edge detectors such as “Canny” & computational intelligent techniques like ACO, GA and PSO are compared with proposed algorithm. Precision, Recall & F-Score is used as performance parameters for these edge detection techniques. The ground truth images are taken as reference edge images and all the edge images acquired by different edge detection systems are contrasted with reference edge image with ascertain the Precision, Recall and F-Score. The techniques are tested on 500 test images from the “BSD500” datasets. The empirical results presented by the proposed algorithm performance better than other edge detection techniques in the images. The proposed method observes edges more accurately and smoothly than other edge detection techniques such as “Canny, ACO, GA and PSO” in different images.

3D image registration of CT and MRI data is carried out using DTCWT sub bands by considering the features from all 64 bands. The features are selected by considering Mattes Mutual Information Metric and the optimizer algorithm estimates the optimum transformation parameters from all the 64 bands. Transformation parameters from eight low pass bands from each octave are averaged to identify optimum registration parameters. Similarly, for registration of high pass bands mean of transformation parameters from 56 bands are identified. The proposed registration algorithm is suitable for register multimodal medical images and the proposed algorithm is validated for more than 20 3D images. Mutual information and joint entropy is estimated to demonstrate the advantages of proposed algorithm overt that of intensity based algorithm. With features identified from 56 bands with six orientations the registered image is found to consist of features from both input images with closeness level measured to be within 12%.

Wireless Sensor Network is used in an extensive assortment of applications like enemy vehicle motion detection, surveillance of the environment. For the network to be operational and for longer maintenance of WSN low-cost sensor nodes are the need of the hour. There are many constraints in the WSN network like deployment constraints, energy constraints and hardware constraints which must be handled in a careful manner in order to improve network lifetime. To improve the network lifetime there are techniques which come under beam forming, connectivity factor, coverage and harvesting factors. In this paper, the survey is done on the innumerable delineations of network lifetime and the methods which can help in improving the network lifetime. Battery Level management during the routing process as well as approaches to identify and reduce the number of dead nodes will also improve lifetime.

Indexing of code vectors is a most difficult task in lattice vector quantization. In this work we focus on the problem of efficient indexing and coding of indexes. Index assignment to the quantized lattice vectors is computed by direct indexing method, through which a vector can be represented by a scalar quantity which represents the index of that vector. This eliminates the need of calculating the prefix i.e. index of the radius ( R) or norm and suffix i.e. the index of the position of vector on the shell of radius R, also eliminates index assignment to the suffix based on lattice point enumeration or leader’s indexing . Two value golomb coding is used to enumerate indices of quantized lattice vectors. We use analytical means to emphasize the dominance of two value golomb code over one value golomb code. This method is applied to achieve image compression. Indexes of particular subband of test images like barbara, peppers and boat are coded using 2-value golomb coding (2-V GC) and compression ratio is calculated. We demonstrate the effectiveness of the 2-V GC while the input is scanned columnwise as compare to rowwise. Experimentally we also show that good compression ratio is achieved when only higher order bits of the indexes are encoded instead of complete bits.

Mobile Ad-Hoc Network (MANET) is a self-structured and self-controlled network. The nodes can sense, process and communicate wirelessly. They are portable, compact and battery powered. These abilities of MANETs make them useful for the applications where fixed infrastructure is not available or is temporarily down due some calamity. They can be used in rescue/disaster relief operation, forest animal surveillance, military surveillance and data exchange in lecture hall etc. Researchers are working on various constraints of MANET, such as limited battery power and bandwidth, lack of central administration and security, need of specialized routing etc. But easy deployment without necessity of physical infrastructure makes MANETs a preferred choice for “wireless communication network”. Researchers have used different techniques viz. simulation, emulation and real world implementation to evaluate the performance of MANET to reduce the impact of these limitations. Simulations assume real time scenarios to test the performance which many a times may not result into expected outcomes. Emulation enables repetitive testing of network scenarios with constraints much similar to the real world, but their per node deployment price is greater than simulation. The simplest form of real world implementation of MANET node can be an embedded circuit with microcontroller, radio transceiver, power source, memory and sensor/s module. This paper presents a study on performance evaluation of low power and low cost - “ZigBee/IEEE 802.15.4” as a wireless radio transceiver in the node design. The experimental analysis of variation in number of obstacles and distance between the nodes that affects the performance of the network in terms of range, network area, packet delivery ratio and latency is presented. Considering the performance of ZigBee with its limitations can help researchers to decide the suitable environment, distance between nodes and frame size to establish a wireless ad hoc network for reliable and efficient communication.

Hydrogen has already been identified as a potential candidate capable of replacing fossil fuels because of its immense energy content compared to conventional fuels. However, finding the safe, efficient generation and storage of hydrogen is a challenge. The present paper reports on hydrogen generation and its subsequent adsorption-desorption process in a proton battery with varied catalyst loading. The method of porous carbon electrode fabrication and experimentation is disclosed. The scanning electron microscopy (SEM) is employed to determine morphology characteristics of the fabricated electrodes that are integrated in a proton battery to study the process of hydrogen adsorption and desorption under the influence of varied catalytic loading. The comparison between catalytic loading of 1 mg/cm2 and 2 mg/cm2 is analysed and reported. The hydrogen storage capacity of activated carbon electrode employed in a proton battery is obtained to be in the range of 0.4 to 0.5 wt. %. The obtained result proves the technical feasibility of a hydrogen generation and its subsequent adsorption in an ionic form within a proton battery. The obtained results contribute towards finding a sustainable alternative solution to fossil-based fuels for the global energy demand.

Natural Gas is More Efficient than Other Forms of Fossil Fuel. Natural gas produces more energy than any of the fossil fuels. Although the primary use of natural gas is as a fuel, it is also a source of hydrocarbons for petrochemical feedstocks and a major source of elemental sulfur, an important industrial chemical. The process simulation and optimization of natural gas dehydration process including mono ethylene glycol (MEG) injection and its regeneration process is studied in this research work. This study also carried out the operation parameters and optimization. The simulation is carried out using Aspen-HYSYS. The effect of replacement MEG by DEG and influence of replacement of Chiller by a turbo expander refrigeration technique on the DPCU operation was studied. The result obtained for optimum parameters like inlet pressure and temperature of the LTS are studied and comparing chiller and expander to maximize NGL are presented. The study recommends to use the expander instead of the chiller. The the economic evaluation of the proposed modification is presented in this study.

SAR ADC has a moderate speed, Low area and low cost compared to other ADC implementations. The accuracy expected from a commercial SAR ADC is very high and research has been going on for many years to improve the accuracy. The Linearity of the data converters is the key for accuracy. The Integral nonlinearity and differential nonlinearity errors of data converters are governed by the matching of the unit capacitors/resistors with in capacitor/resistor array. Layout of these arrays can add significant parasitics affecting the nonlinearity of data converters. This paper presents a layout technique to reduce the impact of the parastics on data converter’s nonlinearity.

This paper explores the aspects of providing education through E-learning model evaluating its relevance to distance education and for ICT systems. A subset of E-learning is a Web based learning that makes the learning -easier, impressive, structured and properly managed. The paper defines an university ontology describing how e-learning provides resources which are available online and designated cloud that can be delivered anywhere any time among the users. In the proposed model data is stored in designated cloud and users are able to share efficiently the same as it provides services to learner. Provenance or trust with respect to the academic resource is a major concern in these types of models, users accessing data must be trustable which help learners, researchers, developers, and users in future work also. This paper proposes an e-learning model which is well organized and structured, such that the machine responds with the accurate, trustable, desired information and results. The paper defines an ontology for semantic structuring, semantic rendering and applies provenance on suggested ontology to achieve authentic results. It is also desired to establish trust of the source contents of the Semantic Web, with the result that a user receiving data will need to verify whether the received data from source is in fact trustable or not. The defined ontogoly is suitable for consumption of both man and machine in the context of the e-learning and Semantic data rendering Web Keywords

Health care is a universally considered as a merit good sector as most countries either have a universal health care system or a universal insurance system. India has been following a hybrid system where predominantly the health logistics and health care have been provided by the State and Central government. From a fledgling beginning with Employees' State Insurance Corporate (ESIC) (1952) and Central Government health Scheme (CGHS) (1954), India has come a long way where it has witnessed a plethora of health insurance programs. The latest addition has been the Ayushman Bharat Health Insurance Scheme, which promises to cover 10 crore families with an insurance coverage of 5 lakh. This study tries to compare the Customer Satisfaction Index (CSI) of Government Sponsored Health Insurance scheme with Private Health Insurance alternatives. It has studied two cities (Bhubaneswar and Cuttack) of Odisha, by taking a sample of 400. The Composite Satisfaction Index has taken four parameters viz. value for money (VFM), affordability, claim settlement process and claim settlement amount, to have a comparative picture of the overall satisfaction level. The broad findings are that the overall satisfaction level of government sponsored schemes is significantly higher than the private schemes; largely due to the higher cost of the private insurance scheme. The study does not take into account variables like age, number of dependents, education etc. for arriving the satisfaction index. All the same, it shows broad trends as to how due to high cost of premium and processing hassles, the private insurance schemes have not been able to become the preferred option for those below poverty line and low income groups.

Forming deposits, which remains unutilized and frequently cause ecological issues, could play an important role as energy source to fulfill the energy requirements. Present investigation has been carried out in a cold bed set up to know the hydrodynamic parameters of fluidized bed at atmospheric conditions. To execute this work a round cross-sectional vessel of 0.09 m internal diameter and 1.2 m height was fabricated using 4 mm thick transparent acrylic resin tube. Sand is chosen as an inert bed with mean diameter 0.4, 0.66 and 0.93 mm. Experiments are then conducted at different fluidizing velocities various from 0.272 to 0.544 m/s with three different fuels rice husk, saw dust and groundnut shells. The impact of sand molecule size on fluidization velocity of two components bio-fuel and sand is studied and recommended to use sand molecule of size 0.4 mm for rice husk, saw dust and 0.66 mm sand particle size for ground nut shells. Group of simulations are done through ANSYS FLUENT16; keeping bed conditions is same as that of experiment. The outcomes are presented in the form of contour plots with volume fraction of sand and biomass particles. Experimental data were compared with the simulation the resultsfollowed almost the same trend.

Neuromorphic computing is a non-von Neumann architecture which is also referred to as artificial neural network and that allows electronic system to function in the same manner as that of the human brain. In this paper we have developed neural core architecture analogous to that of the human brain. Each neural core has its own computational element neuron, memory to store information and local clock generator for synchronous functioning of neuron along with asynchronous input-output port and its port controller. The neuron model used here is a tailor-made of IBM TrueNorth’s neuron block. Our design methodology includes both synchronous and asynchronous circuit in order to build an event-driven neural network core. We have first simulated our design using Neuroph studio in order to calculate the weights and bias value and then used these weights for hardware implementation. With that we have successfully demonstrated the working of neural core using XOR application. It was designed in VHDL language and simulated in Xilinx ISE software.
