Co-creating Value For Smart Phone Operating Systems Via Virtual Discussion Forums

In the traditional way, value is created by manufacturer or producer of a product without engaging the customers. So, traditionally value creation is a monopoly in the part of a manufacturer. After gathering all the raw materials the manufacturers are inserting value to a product. And the inserted value is recognized in the time of consuming the product. In the modern time though there is traditional way of value creation but with the increase of more educated, smart, and technically sound customers the idea of value creation has changed. Now, customers are also contributing in value creation as value co-creator even before the product is consumed. This scenario has been encountered in the thesis with the main purpose of how value is cocreated in smart phone operating systems. The purpose is further divided into the following supobjectives: o What is value co-creation in smart phone operating systems? o Who participates in value co-creation in smart phone operating systems? o What are the procedures that are involved in value co-creation in smart phone operating systems? The research was conducted as a qualitative desk study by observing two of the leading smart phone operating system providers. Data has been collected from the official discussion forum of both the operating system providers. Other general concepts relating to the purpose of the study has been encountered through literature review. The research findings reveal that customers and companies both together co-create value of anticipated level when they communicate and interact with each other. However, most of the time customer to customer interactions, dialogues and discussions that come out in the core conversation help the value co-creation. The value co-creation framework sets up the customer at the main focus of value creation theory. By nullifying the inherited notion that companies only create value within its boundary and provide it to their customers in exchange of currencies. Rationally, it has been commenced that the firms are merely compromising value propositions to its customers. But the value has been co-created in a point where offerings are combined and interacted with customers’ capabilities, knowledge, resources and perceptions. This new perspective has radically altered the prospect of firms towards its customers. Typically customers are now taking part in value cocreation as a crucial member.

Slogger: a profiling and analysis system based on semantic web technologies

Increasingly, distributed systems are being used to host all manner of applications. While these platforms provide a relatively cheap and effective means of executing applications, so far there has been little work in developing tools and utilities that can help application developers understand problems with the supporting software, or the executing applications. To fully understand why an application executing on a distributed system is not behaving as would be expected it is important that not only the application, but also the underlying middleware, and the operating system are analysed too, otherwise issues could be missed and certainly overall performance profiling and fault diagnoses would be harder to understand. We believe that one approach to profiling and the analysis of distributed systems and the associated applications is via the plethora of log files generated at runtime. In this paper we report on a system (Slogger), that utilises various emerging Semantic Web technologies to gather the heterogeneous log files generated by the various layers in a distributed system and unify them in common data store. Once unified, the log data can be queried and visualised in order to highlight potential problems or issues that may be occurring in the supporting software or the application itself.

A methodology to measure the environmental impact of ICT operating systems across different device platforms

Abstract: A new methodology was created to measure the energy consumption and related green house gas (GHG) emissions of a computer operating system (OS) across different device platforms. The methodology involved the direct power measurement of devices under different activity states. In order to include all aspects of an OS, the methodology included measurements in various OS modes, whilst uniquely, also incorporating measurements when running an array of defined software activities, so as to include OS application management features. The methodology was demonstrated on a laptop and phone that could each run multiple OSs, results confirmed that OS can significantly impact the energy consumption of devices. In particular, the new versions of the Microsoft Windows OS were tested and highlighted significant differences between the OS versions on the same hardware. The developed methodology could enable a greater awareness of energy consumption, during both the software development and software marketing processes.

Upgrading a TCABR data analysis and acquisition system for remote participation using Java, XML, RCP and modern client/server communication/authentication

The TCABR data analysis and acquisition system has been upgraded to support a joint research programme using remote participation technologies. The architecture of the new system uses Java language as programming environment. Since application parameters and hardware in a joint experiment are complex with a large variability of components, requirements and specification solutions need to be flexible and modular, independent from operating system and computer architecture. To describe and organize the information on all the components and the connections among them, systems are developed using the extensible Markup Language (XML) technology. The communication between clients and servers uses remote procedure call (RPC) based on the XML (RPC-XML technology). The integration among Java language, XML and RPC-XML technologies allows to develop easily a standard data and communication access layer between users and laboratories using common software libraries and Web application. The libraries allow data retrieval using the same methods for all user laboratories in the joint collaboration, and the Web application allows a simple graphical user interface (GUI) access. The TCABR tokamak team in collaboration with the IPFN (Instituto de Plasmas e Fusao Nuclear, Instituto Superior Tecnico, Universidade Tecnica de Lisboa) is implementing this remote participation technologies. The first version was tested at the Joint Experiment on TCABR (TCABRJE), a Host Laboratory Experiment, organized in cooperation with the IAEA (International Atomic Energy Agency) in the framework of the IAEA Coordinated Research Project (CRP) on ""Joint Research Using Small Tokamaks"".

A Management Tool for the Replication of Operating Systems in Wireless Communication Networks

To simplify computer management, various administration systems based on wired connections adopt advanced techniques to manage software configuration. Nevertheless, the strong relation between hardware and software makes for an individualism of that management, besides penalizing computational mobility and ubiquity. All these issues lead to degradation of scalability, flexibility and the facility to install and maintain distributed applications. This article presents an environment for centralized wireless communication network management, named WSE-OS (Wireless Sharing Environment - Operating Systems): a model based on Virtual Desktop Infrastructure (VDI) which associates virtualization techniques and safe remote access systems to create a distributed architecture as a base for a managing system. WSE-OS is capable of accomplishing the replication of operating system images using wireless communication network, besides offering abstraction of hardware to its clients, making the management more flexible and independent of wired connections. Results obtained from this work indicate that WSE-OS allows disseminating, through a single software configuration, the execution of data related to operating system images in client computers. WSE-OS can also be used as a management tool for operating systems in a wireless network.

A malware detection system inspired on the human immune system

Malicious programs (malware) can cause severe damage on computer systems and data. The mechanism that the human immune system uses to detect and protect from organisms that threaten the human body is efficient and can be adapted to detect malware attacks. In this paper we propose a system to perform malware distributed collection, analysis and detection, this last inspired by the human immune system. After collecting malware samples from Internet, they are dynamically analyzed so as to provide execution traces at the operating system level and network flows that are used to create a behavioral model and to generate a detection signature. Those signatures serve as input to a malware detector, acting as the antibodies in the antigen detection process. This allows us to understand the malware attack and aids in the infection removal procedures. © 2012 Springer-Verlag.

Using a threaded framework to enable practical activities in Operating Systems courses

Teaching Operating Systems (OS) is a rather hard task, since being an OS designer is not a desired goal for most students and the subject demands a large amount of knowledge over system's details. To reduce the difficulty many courses are planned with laboratory practices, differing in how the practices are designed. Some try to implement next-to-real kernels, others use simulators, and even others use synthetic kernels. In this paper an approach based on synthetic kernels is described. It uses thread programming in order to establish control over the operating system components. T his approach allows the kernel to grow following the materials presented in the course. It has been successfully applied in two different courses at our University, the first one being a basic OS course and the second one an upper level course. Results from these applications are presented.

Tecniche per il controllo dinamico del consumo di potenza per piattaforme system-on-chip

Providing support for multimedia applications on low-power mobile devices remains a significant research challenge. This is primarily due to two reasons: • Portable mobile devices have modest sizes and weights, and therefore inadequate resources, low CPU processing power, reduced display capabilities, limited memory and battery lifetimes as compared to desktop and laptop systems. • On the other hand, multimedia applications tend to have distinctive QoS and processing requirementswhichmake themextremely resource-demanding. This innate conflict introduces key research challenges in the design of multimedia applications and device-level power optimization. Energy efficiency in this kind of platforms can be achieved only via a synergistic hardware and software approach. In fact, while System-on-Chips are more and more programmable thus providing functional flexibility, hardwareonly power reduction techniques cannot maintain consumption under acceptable bounds. It is well understood both in research and industry that system configuration andmanagement cannot be controlled efficiently only relying on low-level firmware and hardware drivers. In fact, at this level there is lack of information about user application activity and consequently about the impact of power management decision on QoS. Even though operating system support and integration is a requirement for effective performance and energy management, more effective and QoSsensitive power management is possible if power awareness and hardware configuration control strategies are tightly integratedwith domain-specificmiddleware services. The main objective of this PhD research has been the exploration and the integration of amiddleware-centric energymanagement with applications and operating-system. We choose to focus on the CPU-memory and the video subsystems, since they are the most power-hungry components of an embedded system. A second main objective has been the definition and implementation of software facilities (like toolkits, API, and run-time engines) in order to improve programmability and performance efficiency of such platforms. Enhancing energy efficiency and programmability ofmodernMulti-Processor System-on-Chips (MPSoCs) Consumer applications are characterized by tight time-to-market constraints and extreme cost sensitivity. The software that runs on modern embedded systems must be high performance, real time, and even more important low power. Although much progress has been made on these problems, much remains to be done. Multi-processor System-on-Chip (MPSoC) are increasingly popular platforms for high performance embedded applications. This leads to interesting challenges in software development since efficient software development is a major issue for MPSoc designers. An important step in deploying applications on multiprocessors is to allocate and schedule concurrent tasks to the processing and communication resources of the platform. The problem of allocating and scheduling precedenceconstrained tasks on processors in a distributed real-time system is NP-hard. There is a clear need for deployment technology that addresses thesemulti processing issues. This problem can be tackled by means of specific middleware which takes care of allocating and scheduling tasks on the different processing elements and which tries also to optimize the power consumption of the entire multiprocessor platform. This dissertation is an attempt to develop insight into efficient, flexible and optimalmethods for allocating and scheduling concurrent applications tomultiprocessor architectures. It is a well-known problem in literature: this kind of optimization problems are very complex even in much simplified variants, therefore most authors propose simplified models and heuristic approaches to solve it in reasonable time. Model simplification is often achieved by abstracting away platform implementation ”details”. As a result, optimization problems become more tractable, even reaching polynomial time complexity. Unfortunately, this approach creates an abstraction gap between the optimization model and the real HW-SW platform. The main issue with heuristic or, more in general, with incomplete search is that they introduce an optimality gap of unknown size. They provide very limited or no information on the distance between the best computed solution and the optimal one. The goal of this work is to address both abstraction and optimality gaps, formulating accurate models which accounts for a number of ”non-idealities” in real-life hardware platforms, developing novel mapping algorithms that deterministically find optimal solutions, and implementing software infrastructures required by developers to deploy applications for the targetMPSoC platforms. Energy Efficient LCDBacklightAutoregulation on Real-LifeMultimediaAp- plication Processor Despite the ever increasing advances in Liquid Crystal Display’s (LCD) technology, their power consumption is still one of the major limitations to the battery life of mobile appliances such as smart phones, portable media players, gaming and navigation devices. There is a clear trend towards the increase of LCD size to exploit the multimedia capabilities of portable devices that can receive and render high definition video and pictures. Multimedia applications running on these devices require LCD screen sizes of 2.2 to 3.5 inches andmore to display video sequences and pictures with the required quality. LCD power consumption is dependent on the backlight and pixel matrix driving circuits and is typically proportional to the panel area. As a result, the contribution is also likely to be considerable in future mobile appliances. To address this issue, companies are proposing low power technologies suitable for mobile applications supporting low power states and image control techniques. On the research side, several power saving schemes and algorithms can be found in literature. Some of them exploit software-only techniques to change the image content to reduce the power associated with the crystal polarization, some others are aimed at decreasing the backlight level while compensating the luminance reduction by compensating the user perceived quality degradation using pixel-by-pixel image processing algorithms. The major limitation of these techniques is that they rely on the CPU to perform pixel-based manipulations and their impact on CPU utilization and power consumption has not been assessed. This PhDdissertation shows an alternative approach that exploits in a smart and efficient way the hardware image processing unit almost integrated in every current multimedia application processors to implement a hardware assisted image compensation that allows dynamic scaling of the backlight with a negligible impact on QoS. The proposed approach overcomes CPU-intensive techniques by saving system power without requiring either a dedicated display technology or hardware modification. Thesis Overview The remainder of the thesis is organized as follows. The first part is focused on enhancing energy efficiency and programmability of modern Multi-Processor System-on-Chips (MPSoCs). Chapter 2 gives an overview about architectural trends in embedded systems, illustrating the principal features of new technologies and the key challenges still open. Chapter 3 presents a QoS-driven methodology for optimal allocation and frequency selection for MPSoCs. The methodology is based on functional simulation and full system power estimation. Chapter 4 targets allocation and scheduling of pipelined stream-oriented applications on top of distributed memory architectures with messaging support. We tackled the complexity of the problem by means of decomposition and no-good generation, and prove the increased computational efficiency of this approach with respect to traditional ones. Chapter 5 presents a cooperative framework to solve the allocation, scheduling and voltage/frequency selection problem to optimality for energyefficient MPSoCs, while in Chapter 6 applications with conditional task graph are taken into account. Finally Chapter 7 proposes a complete framework, called Cellflow, to help programmers in efficient software implementation on a real architecture, the Cell Broadband Engine processor. The second part is focused on energy efficient software techniques for LCD displays. Chapter 8 gives an overview about portable device display technologies, illustrating the principal features of LCD video systems and the key challenges still open. Chapter 9 shows several energy efficient software techniques present in literature, while Chapter 10 illustrates in details our method for saving significant power in an LCD panel. Finally, conclusions are drawn, reporting the main research contributions that have been discussed throughout this dissertation.

Sicurezza di rete, analisi del traffico e monitoraggio.

Il lavoro è stato suddiviso in tre macro-aree. Una prima riguardante un'analisi teorica di come funzionano le intrusioni, di quali software vengono utilizzati per compierle, e di come proteggersi (usando i dispositivi che in termine generico si possono riconoscere come i firewall). Una seconda macro-area che analizza un'intrusione avvenuta dall'esterno verso dei server sensibili di una rete LAN. Questa analisi viene condotta sui file catturati dalle due interfacce di rete configurate in modalità promiscua su una sonda presente nella LAN. Le interfacce sono due per potersi interfacciare a due segmenti di LAN aventi due maschere di sotto-rete differenti. L'attacco viene analizzato mediante vari software. Si può infatti definire una terza parte del lavoro, la parte dove vengono analizzati i file catturati dalle due interfacce con i software che prima si occupano di analizzare i dati di contenuto completo, come Wireshark, poi dei software che si occupano di analizzare i dati di sessione che sono stati trattati con Argus, e infine i dati di tipo statistico che sono stati trattati con Ntop. Il penultimo capitolo, quello prima delle conclusioni, invece tratta l'installazione di Nagios, e la sua configurazione per il monitoraggio attraverso plugin dello spazio di disco rimanente su una macchina agent remota, e sui servizi MySql e DNS. Ovviamente Nagios può essere configurato per monitorare ogni tipo di servizio offerto sulla rete.

Integration of a data acquisition system based on FlexRIO technology with EPICS

EPICS (Experimental Physics and Industrial Control System) lies in a set of software tools and applications which provide a software infrastructure for building distributed data acquisition and control systems. Currently there is an increase in use of such systems in large Physics experiments like ITER, ESS, and FREIA. In these experiments, advanced data acquisition systems using FPGA-based technology like FlexRIO are more frequently been used. The particular case of ITER (International Thermonuclear Experimental Reactor), the instrumentation and control system is supported by CCS (CODAC Core System), based on RHEL (Red Hat Enterprise Linux) operating system, and by the plant design specifications in which every CCS element is defined either hardware, firmware or software. In this degree final project the methodology proposed in Implementation of Intelligent Data Acquisition Systems for Fusion Experiments using EPICS and FlexRIO Technology Sanz et al. [1] is used. The final objective is to provide a document describing the fulfilled process and the source code of the data acquisition system accomplished. The use of the proposed methodology leads to have two diferent stages. The first one consists of the hardware modelling with graphic design tools like LabVIEWFPGA which later will be implemented in the FlexRIO device. In the next stage the design cycle is completed creating an EPICS controller that manages the device using a generic device support layer named NDS (Nominal Device Support). This layer integrates the data acquisition system developed into CCS (Control, data access and communication Core System) as an EPICS interface to the system. The use of FlexRIO technology drives the use of LabVIEW and LabVIEW FPGA respectively. RESUMEN. EPICS (Experimental Physics and Industrial Control System) es un conjunto de herramientas software utilizadas para el desarrollo e implementación de sistemas de adquisición de datos y control distribuidos. Cada vez es más utilizado para entornos de experimentación física a gran escala como ITER, ESS y FREIA entre otros. En estos experimentos se están empezando a utilizar sistemas de adquisición de datos avanzados que usan tecnología basada en FPGA como FlexRIO. En el caso particular de ITER, el sistema de instrumentación y control adoptado se basa en el uso de la herramienta CCS (CODAC Core System) basado en el sistema operativo RHEL (Red Hat) y en las especificaciones del diseño del sistema de planta, en la cual define todos los elementos integrantes del CCS, tanto software como firmware y hardware. En este proyecto utiliza la metodología propuesta para la implementación de sistemas de adquisición de datos inteligente basada en EPICS y FlexRIO. Se desea generar una serie de ejemplos que cubran dicho ciclo de diseño completo y que serían propuestos como casos de uso de dichas tecnologías. Se proporcionará un documento en el que se describa el trabajo realizado así como el código fuente del sistema de adquisición. La metodología adoptada consta de dos etapas diferenciadas. En la primera de ellas se modela el hardware y se sintetiza en el dispositivo FlexRIO utilizando LabVIEW FPGA. Posteriormente se completa el ciclo de diseño creando un controlador EPICS que maneja cada dispositivo creado utilizando una capa software genérica de manejo de dispositivos que se denomina NDS (Nominal Device Support). Esta capa integra la solución en CCS realizando la interfaz con la capa EPICS del sistema. El uso de la tecnología FlexRIO conlleva el uso del lenguaje de programación y descripción hardware LabVIEW y LabVIEW FPGA respectivamente.

Técnicas de diseño de pruebas en sistemas embebidos

El software es, cada vez más, una parte muy importante de cualquier circuito electrónico moderno, por ejemplo, un circuito realizado con algún tipo de microprocesador debe incorporar un programa de control por pequeño que sea. Al utilizarse programas informáticos en los circuitos electrónicos modernos, es muy aconsejable, por no decir imprescindible, realizar una serie de pruebas de calidad del diseño realizado. Estas pruebas son cada vez más complicadas de realizar debido al gran tamaño del software empleado en los sistemas actuales, por este motivo, es necesario estructurar una serie de pruebas con el fin de realizar un sistema de calidad, y en algunos casos, un sistema que no presente ningún peligro para el ser humano o el medio ambiente. Esta propuesta consta de la explicación de las técnicas de diseño de pruebas que existen actualmente (por lo menos las más básicas ya que es un tema muy extenso) para realizar el control de calidad del software que puede contener un sistema embebido. Además, muchos circuitos electrónicos, debido a su control o exigencia hardware, es imprescindible que sean manipulados por algún programa que requiera más que un simple microprocesador, me refiero a que se deban controlar por medio de un pequeño programa manipulado por un sistema operativo, ya sea Linux, AIX, Unix, Windows, etc., en este caso el control de calidad se debería llevar a cabo con otras técnicas de diseño. También se puede dar el caso que el circuito electrónico a controlar se deba hacer por medio de una página web. El objetivo es realizar un estudio de las actuales técnicas de diseño de pruebas que están orientadas al desarrollo de sistemas embebidos. ABSTRACT. Software is increasingly a very important part of any modern electronic circuit, for example, a circuit made with some type of microprocessor must incorporate a control program no matter the small it is. When computer programs are used in modern electronic circuits, it is quite advisable if not indispensable to perform a series of quality tests of the design. These tests are becoming more and more difficult to be performed due to the large size of the software used in current systems, which is why it is necessary to structure a series of tests in order to perform a quality system, and in some cases, a system with no danger to humans or to the environment. This proposal consists of an explanation of the techniques used in the tests (at least the most basic ones since it is a very large topic) for quality control of software which may contain an embedded system. In addition, a lot of electronic circuits, due to its control or required hardware, it is essential to be manipulated by a program that requires more than a simple microprocessor, I mean that they must be controlled by means of a small program handled by an operating system, being Linux, AIX, Unix, Windows, etc., in this case the quality control should be carried out with other design techniques. The objective is to study the current test design techniques that are geared to the development of embedded systems. It can also occur that the electronic circuit should be controlled by means of a web page.

Este proyecto fin de carrera tiene como finalidad el diseño y la implementación de un sistema de monitorización y gestión dinámica de redes de sensores y actuadores inalámbricos (Wireless Sensor and Actuator Networks – WSAN) en base a la información de configuración almacenada en una base de datos sobre la cual un motor de detección vigila posibles cambios. Este motor informará de los cambios a la herramienta de gestión y monitorización de la WSAN para que sean llevados a cabo en la red desplegada. Este trabajo se enmarca en otro más amplio cuya finalidad es la demostración de la posibilidad de reconfigurar dinámicamente una WSAN utilizando los mecanismos propios de las Líneas de Productos Software Dinámicos (DSPL, por sus siglas en inglés). Se ha diseñado e implementado el software que proporciona los métodos necesarios para la comunicación y actuación sobre la red de sensores y actuadores inalámbricos, además de permitir el control de cada uno de los dispositivos pertenecientes a dicha red y que los dispositivos se incorporen a dicha red de manera autónoma. El desarrollo y pruebas de este proyecto fin de carrera se ha realizado utilizando una máquina virtual sobre la que se ha configurado convenientemente una plataforma que incluye un emulador de red de sensores y actuadores de tecnología SunSpot (Solarium) y todas las herramientas de desarrollo y ejecución necesarias (entre ellas, SunSpot SDK 6.0 y NetBeans). Esta máquina virtual ejecuta un sistema operativo Unix (Ubuntu Server 12.4) y facilita el rápido despliegue de las herramientas implementadas así como la integración de las mismas en desarrollos más amplios. En esta memoria se describe todo el proceso de diseño e implementación del software desarrollado, las conclusiones obtenidas de su ejecución y una guía de usuario para su despliegue y manejo. ABSTRACT. The aim of this project is the design and implementation of a system to monitor and dynamically manage a wireless sensor and actuator network (WSAN) in consistence with the configuration information stored in a database whose changes are monitored by a so-called monitoring engine. This engine informs the management and monitoring tool about the changes, in order for these to be carried out on the deployed network. This project is a part of a broader one aimed at demonstrating the ability to dynamically reconfigure a WSAN using the mechanisms of the Dynamic Software Product Lines (DSPL). A software has been designed and implemented which provides the methods to communicate with and actuate on the WSAN. It also allows to control each of the devices, as well as their autonomous incorporation to the network. Development and testing of this project was done using a virtual machine that has a conveniently configured platform which includes a SunSpot technology WSAN emulator (Solarium) as well as all the necessary development and implementation tools (including SunSpot 6.0 SDK and NetBeans). This virtual machine runs a Unix (Ubuntu Server 12.4) operating system and makes it easy to rapidly deploy the implemented tools and to integrate them into broader developments. This document explains the whole process of designing and implementing the software, the conclusions of execution and a user's manual.

Análisis de reflectores en MatLab

Sabor, Software de Análisis de BOcinas y Reflectores, es una herramienta didáctica la cual es utilizada en los laboratorios de la escuela para realizar prácticas de la asignatura Antenas y Compatibilidad Electromagnética, esta herramienta da a los alumnos una visión gráfica de lo que se enseña en clase de teoría de lo que son los campos en las aperturas de los reflectores. El proyector pretende sustituir al primer Sabor , ya que se queda obsoleto debido al sistema operativo, ya que funciona solo para Windows XP y con ordenadores de 32 bits, y también realizar mejoras y corregir errores de la versión anterior. El proyecto se ha desarrollado en Matlab que es un software matemático con grandes ventajas en cuanto a cálculo, desarrollo gráfico, y a la creación de nuevos algoritmos en su propio lenguaje y además está disponible para las plataformas Unix, Windows, Mac OSX y GNU/Linux. El objetivo del proyecto ha sido implementar, al igual que las versiones anteriores, cinco tipos de reflectores, como son: Parabólico, Offset, Cassegrain y los dos Dobles Offset, Cassegrain y Gregorian, y han sido analizados con un alimentador ideal ,cos-q, y por último los resultados obtenidos se han comparado con las versiones anteriores de Sabor, como son Sabor 3.0 y el primer Sabor. El proyecto consta de partes muy bien diferencias como son :  La interpretación correctas de las formulas que se han utilizado para la realización de este proyecto ,dichas formulas han sido las dadas por el proyecto fin de carrera titulado Sabor3.0 de Francisco Egea Castejón.  GUIDE, the graphical user interface development environment, con el que se creó: GUI, graphical user interface, que es la parte de Matlab dedicada a crear interfaces de usuario , herramienta utilizada para crear nuestras distintas ventanas dedicadas para la obtención de datos para analizar los distintos reflectores y para mostrar por pantalla los distintos resultados.  Programación Orientada a Objetos de Matlab y sus distintas propiedades como son la herencia lo cual es muy útil para ocupar menos memoria ya que con un único método podemos realizar distintos cálculos con los distintos reflectores, objetos, solo cambiando las propiedades de cada objeto  Y por último ha sido la realización de validación de los resultados con la ayuda de las versiones anteriores de Sabor, que están detallados en el capítulo 5 y la unión con bocinas del proyecto fin de carrera Análisis de Bocinas en Matlab de Javier Montero. Por otra parte tenemos las mejoras realizadas a las antiguas versiones como son: realización de registros que el usuario puede guardar y cargar con las distintas variables, también se ha realizado un fichero .txt en el que consta la amplitud del campo con su respectiva theta para que el usuario pueda visualizarlo en cualquier plataforma gráfica de datos como por ejemplo exel. ABSTRACT. Sabor, Software de Análisis de BOcinas y Reflectores, is a teaching tool, which is used to do laboratory practice in the subject of Antennas y Compatibilidad Electromagnética, this tool gives students a graphic view of the knowledge that are given in theory class in regard to aperture field of reflectors. This project intend to replace the first Sabor, because it is outdated, due to the operating system, because Sabor works only with Widows XP and computer with 32 bits, and to make improves and correct errors that were detected in the last version of Sabor too. This project has been carried out in Matlab, which is a mathematical software with high-level language for numerical computation, visualization and application development, and furthermore it is available to different platforms such as Unix, Windows ,Mac OSX and GNU/Linux This project has focused on implementing, the same as last versions, five kind of reflectors, such as : Parabolic, Offset, Cassegrain and two offset dual reflector Cassegrain y Gregorian ,and these were analysed with a cos-q ideal feed, and finally the results were checked with the versions of Sabor, as well as Sabor 3.0 and the first Sabor. This project consist of four parts:  The correct interpretation of the formulas , which were used to do this project, from the final project Sabor3.0 by Francisco Egea Castejón.  GUIDE, the graphical user interface development environment, tool that was used to create : GUI, graphical user interface, part of Matlab dedicated to create user interface.  Object Oriented Programming of Matlab and different properties like inheritance, that is very useful for saving memory space because with only one method we can analyse different kind of reflectors, object, only change the properties of the object.  At finally, the results were contrasted with the results from the previous versions and the link reflectors with horns from the final project Análisis de Bocinas en Matlab by Javier Montero. On the other hand, we have the improvements such as: registers and .txt file. The registers are used by user to save and load different variables and .txt file is useful because it allows to the user plotting in different platforms for example exel.
