Monitorización de sistemas en alta disponibilidad

El objetivo del proyecto es implantar un sistema de monitorización, con la peculiaridad de encontrarse en alta disponibilidad, esto es, que el servicio (la monitorización de una infraestructura) se preste forma continua y no se vea interrumpido. Dado que el propósito del sistema es monitorizar activamente una infraestructura, ha sido necesario desplegar una infraestructura, además del sistema de monitorización. La infraestructura en cuestión está compuesta por un servidor de documentación, un servidor de base de datos, un servidor de aplicaciones y un servidor web. El sistema de monitorización se ha desplegado en la misma red de área local de esta infraestructura y monitoriza que los servicios prestados por los componentes de esta infraestructura se encuentren operativos y funcionando adecuadamente. Así pues, se tendría un sistema de monitorización local funcional. No obstante, el proyecto plantea un sistema escalable, que esté preparado para el crecimiento de la infraestructura y continúe siendo eficiente. Para ello, sistema de monitorización se encuentre dividido por dos componentes:  Sonda delegada: monitoriza localmente los activos de la infraestructura a monitorizar, es el escenario anteriormente descrito.  Sonda maestra: recibe los resultados de la monitorización realizada, este sistema puede estar desplegado en otra red distinta a la sonda delegada. Este enfoque no solo es escalable, sino también es fiel a la realidad, pues puede darse el caso de que las sondas pertenezcan a distintas infraestructuras e inclusive, distintas organizaciones, y se comuniquen a través de internet, mediante un mecanismo confiable a ser posible. El proyecto plantea que ambas sondas se encuentren en alta disponibilidad (en adelante HA, referente a high availability), y que cada sonda está compuesta por dos equipos (nodos, en adelante). Como se analizará en posteriores capítulos, existen diversas configuraciones que permiten implantar un sistema en HA, la configuración escogida para el proyecto es Activo – Pasivo(los detalles de esta configuración también se explican en posteriores capítulos). Para finalizar, se estudiara la posibilidad de ofrecer respuestas activas en ciertas situaciones y configuraciones adicionales sobre el sistema de monitorización base. Por otro lado, para la implantación del proyecto se ha usado software de código abierto para la virtualización de la infraestructura (Virtual Box y GNS3), los sistemas operativos base (Linux), el sistema de monitorización(Nagios Core) así como el software que implementa la HA (corosync y pacemaker).---ABSTRACT---The aim of the Project is to implement a monitoring system, with the peculiarity of being deployed in high availability, what it is that the service (monitoring infrastructure) is provided continuously and not interrupted. As the purpose of the system is monitoring infrastructure actively, an infrastructure has been deployed, and also the monitoring system. The infrastructure monitored is composed of a documentation server, a server database, an application server and a Web server. The monitoring system has been also deployed on the same LAN of this infrastructure and monitors the services provided by the components of this infrastructure are operational and working as expected. This is a local monitoring system functional. However, the project also proposes a scalable system that is ready for growth of infrastructure and efficient. This is the reason of divide the system in two components:  Slave Component: monitors locally the infrastructure assets to be monitored, this is the scenario described above.  Master Component: get the results from the monitoring, provided by the Slave Component. This system can be deployed in a different network than the slave component. This approach is not only scalable but also a real scenario, as may be the case that the Components belongs to different infrastructures and even, different organizations, also this components can communicate over the Internet, through a reliable mechanism if possible. The project proposes that both Components are deployed in high availability (HA onwards concerning high availability), each Component is composed of two servers (nodes, hereafter). As will be discussed in later chapters, there are several settings available to deploy a system in HA, the configuration chosen for the project is Active - Passive (details of this configuration are also explained in later chapters). Finally the possibility of offering active responses in certain situations and additional settings on the monitoring system will be discussed. On the other hand, for the implementation of the project, open source software has been used, for virtualization infrastructure (Virtual Box and GNS3), code-based operating systems (Linux), the monitoring system (Nagios core), as well as the software that implements the HA (corosync and pacemaker).

Aplicación distribuida para la monitorización y diagnosis de automóviles

En este proyecto se va desarrollar una aplicación distribuida para la diagnosis y monitorización de automóviles. Se pretende poder realizar estas funciones en prácticamente cualquier automóvil del mercado (con fabricación a partir del año 1996 para el caso de automóviles gasolina y para el año 2000 en el caso de automóviles diésel) de manera remota, aprovechando la conectividad a Internet que actualmente brindan la mayoría de los smartphones. La viabilidad del proyecto reside en la existencia de estándares para la diagnosis de la electrónica del motor. Para poder llevar a cabo esta tarea, se empleará una interfaz de diagnóstico ELM327 bluetooth, que servirá de enlace entre el vehículo y el teléfono móvil del usuario y que a su vez se encargara de enviar los datos que reciba del vehículo a un terminal remoto. De esta manera, se tendrá la aplicación dividida en dos partes: por un lado la aplicación que se ejecuta en el terminal móvil del usuario que actuará como parte servidora, y por el otro la aplicación cliente que se ejecutará en un terminal remoto. También estará disponible una versión de la aplicación servidora para PC. El potencial del proyecto reside en la capacidad de visualización en tiempo real de los parámetros más importantes del motor del vehículo y en la detección de averías gracias a la funcionalidad de lectura de la memoria de averías residente en el vehículo. Así mismo, otras funcionalidades podrían ser implementadas en posteriores versiones de la aplicación, como podría ser el registro de dichos parámetros en una base de datos para su posterior procesado estadístico; de este modo se podría saber el consumo medio, la velocidad media, velocidad máxima alcanzada, tiempo de uso, kilometraje diario o mensual… y un sin fin de posibilidades. ABSTRACT. In this project a distributed application for car monitor and diagnostic is going to be developed. The idea is to be able to connect remotely to almost any car (with production starting in 1996 in the case of petrol engines and production starting in 2000 in case of diesel engines) using the Internet connection available in almost every smartphone. The project is viable because of the existence of standards for engine electronic unit connection. In order to do that, an ELM327 bluetooth interface is going to be used. This interface works as a link between the car and the smartphone, and it is the smartphone which sends the received data from the car to a remote terminal (computer). Thus, the application is divided into two parts: the server which is running on smartphone and the client which is running on a remote terminal. Also there is available a server application for PC. The potential of the project lies in the real-time display data capacity of the most important engine parameters and in the diagnostic capacity based on reading fault memory. In addition, other features could be implemented in later versions of the application, as the capacity of record data for future statistic analysis. By doing this, it is possible to know the average fuel consumption, average speed, maximum speed, time of use, daily or monthly mileage… and an endless number of possibilities.

Análisis de ataques avanzados y sus técnicas de detección

Los ataques a redes de información son cada vez más sofisticados y exigen una constante evolución y mejora de las técnicas de detección. Para ello, en este proyecto se ha diseñado e implementado una plataforma cooperativa para la detección de intrusiones basada en red. En primer lugar, se ha realizado un estudio teórico previo del marco tecnológico relacionado con este ámbito, en el que se describe y caracteriza el software que se utiliza para realizar ataques a sistemas (malware) así como los métodos que se utilizan para llegar a transmitir ese software (vectores de ataque). En el documento también se describen los llamados APT, que son ataques dirigidos con una gran inversión económica y temporal. Estos pueden englobar todos los malware y vectores de ataque existentes. Para poder evitar estos ataques, se estudiarán los sistemas de detección y prevención de intrusiones, describiendo brevemente los algoritmos que se tienden a utilizar en la actualidad. En segundo lugar, se ha planteado y desarrollado una plataforma en red dedicada al análisis de paquetes y conexiones para detectar posibles intrusiones. Este sistema está orientado a sistemas SCADA (Supervisory Control And Data Adquisition) aunque funciona sobre cualquier red IPv4/IPv6, para ello se definirá previamente lo que es un sistema SCADA, así como sus partes principales. Para implementar el sistema se han utilizado dispositivos de bajo consumo llamados Raspberry PI, estos se ubican entre la red y el equipo final que se quiera analizar. En ellos se ejecutan 2 aplicaciones desarrolladas de tipo cliente-servidor (la Raspberry central ejecutará la aplicación servidora y las esclavas la aplicación cliente) que funcionan de forma cooperativa utilizando la tecnología distribuida de Hadoop, la cual se explica previamente. Mediante esta tecnología se consigue desarrollar un sistema completamente escalable. La aplicación servidora muestra una interfaz gráfica que permite administrar la plataforma de análisis de forma centralizada, pudiendo ver así las alarmas de cada dispositivo y calificando cada paquete según su peligrosidad. El algoritmo desarrollado en la aplicación calcula el ratio de paquetes/tiempo que entran/salen del equipo final, procesando los paquetes y analizándolos teniendo en cuenta la información de señalización, creando diferentes bases de datos que irán mejorando la robustez del sistema, reduciendo así la posibilidad de ataques externos. Para concluir, el proyecto inicial incluía el procesamiento en la nube de la aplicación principal, pudiendo administrar así varias infraestructuras concurrentemente, aunque debido al trabajo extra necesario se ha dejado preparado el sistema para poder implementar esta funcionalidad. En el caso experimental actual el procesamiento de la aplicación servidora se realiza en la Raspberry principal, creando un sistema escalable, rápido y tolerante a fallos. ABSTRACT. The attacks to networks of information are increasingly sophisticated and demand a constant evolution and improvement of the technologies of detection. For this project it is developed and implemented a cooperative platform for detect intrusions based on networking. First, there has been a previous theoretical study of technological framework related to this area, which describes the software used for attacks on systems (malware) as well as the methods used in order to transmit this software (attack vectors). In this document it is described the APT, which are attacks directed with a big economic and time inversion. These can contain all existing malware and attack vectors. To prevent these attacks, intrusion detection systems and prevention intrusion systems will be discussed, describing previously the algorithms tend to use today. Secondly, a platform for analyzing network packets has been proposed and developed to detect possible intrusions in SCADA (Supervisory Control And Data Adquisition) systems. This platform is designed for SCADA systems (Supervisory Control And Data Acquisition) but works on any IPv4 / IPv6 network. Previously, it is defined what a SCADA system is and the main parts of it. To implement it, we used low-power devices called Raspberry PI, these are located between the network and the final device to analyze it. In these Raspberry run two applications client-server developed (the central Raspberry runs the server application and the slaves the client application) that work cooperatively using Hadoop distributed technology, which is previously explained. Using this technology is achieved develop a fully scalable system. The server application displays a graphical interface to manage analytics platform centrally, thereby we can see each device alarms and qualifying each packet by dangerousness. The algorithm developed in the application calculates the ratio of packets/time entering/leaving the terminal device, processing the packets and analyzing the signaling information of each packet, reating different databases that will improve the system, thereby reducing the possibility of external attacks. In conclusion, the initial project included cloud computing of the main application, being able to manage multiple concurrent infrastructure, but due to the extra work required has been made ready the system to implement this funcionality. In the current test case the server application processing is made on the main Raspberry, creating a scalable, fast and fault-tolerant system.

Embedded Linux integration using Linuxlink tool and peripheral driver development for Zedboard

This project is divided into two main parts: The first part shows the integration of an Embedded Linux operating system on a development hardware platform named Zedboard. This platform contains a Zynq-7000 System on Chip (Soc) which is composed by two dual core ARM Cortex-A9 processors and a FPGA Artix-7. The Embedded Linux is built with Linuxlink, a Timesys tool. Meanwhile, the platform hardware configuration is done with Xilinx Vivado. The system is loaded with an SD card which requires to have every files needed for the booting process and for the operation. Some of these files are generated with Xilinx SDK software. The second part starts up from the system already built to integrate a peripheral in the Zynq-7000 FPGA. Also the drivers for controlling the peripheral from the operating system are developed. Finally, a user space program is created to test both of them. RESUMEN. Este proyecto consta de dos partes: La primera muestra la integración de un sistema operativo Linux embebido en una plataforma de desarrollo hardware llamada Zedboard. Esta plataforma utiliza un System on Chip (SoC) Zynq-7000 que está formado por dos procesadores ARM Cortex-A9 de doble núcleo y una FPGA Artix-7. El Linux embebido se construye utilizando la herramienta Linuxlink de Timesys, mientras que el hardware de la plataforma de desarrollo se configura con Vivado de Xilinx. El sistema se carga en una tarjeta SD que debe tener todos los archivos necesarios para completar el arranque y hacer funcionar el sistema. Algunos de esos archivos se generan con la herramienta SDK de Xilinx. En la segunda parte se utiliza el sistema construido para integrar un periférico en la FPGA del Zynq-7000, haciendo uso de Vivado, y se desarrollan los drivers necesarios para utilizarlo mediante el sistema operativo. Para probar esta última parte se desarrolla un programa de espacio de usuario.

Sistema de alarmas asistenciales para hospitales y residencias

En los hospitales y residencias geriátricas de hoy en día es necesario que tengan un sistema asistencial paciente-enfermera. Este sistema debe ser capaz de controlar y gestionar cada una de las alarmas que se puedan generar en el menor tiempo posible y con la mayor eficacia. Para ello se ha diseñado una solución completa llamada ConnectCare. La arquitectura modular del sistema y la utilización de comunicación IP permiten adaptar el sistema a cada situación proporcionando soluciones específicas a medida. Este sistema se compone de un software llamado Buslogic que gestiona las alarmas en un servidor y de unos dispositivos llamados Fonet Control TCP/IP que posee una doble función: por una parte, sirve como dispositivo intercomunicador telefónico y por otra parte, sirve como dispositivo de gestión de alarmas y control de otros dispositivos externos. Como dispositivo intercomunicador telefónico, se integra en la red telefónica como un terminal de extensión analógica permitiendo la intercomunicación entre el paciente y el personal sanitario. Se hará una breve descripción de la parte intercomunicadora pero no es el objeto de este proyecto. En cambio, en la parte de control se hará más hincapié del diseño y su funcionamiento ya que sí es el objeto de este proyecto. La placa de control permite la recepción de señales provenientes de dispositivos de llamadas cableados, como son pulsadores asistenciales tipo “pera” o tiradores de baño. También es posible recibir señales de alerta de dispositivos no estrictamente asistenciales como detectores de humo o detectores de presencia. Además, permite controlar las luces de las habitaciones de los residentes y actuar sobre otros dispositivos externos. A continuación se mostrará un presupuesto para tener una idea del coste que supone. El presupuesto se divide en dos partes, la primera corresponde en el diseño de la placa de control y la segunda corresponde a la fabricación en serie de la misma. Después hablaremos sobre las conclusiones que hemos sacado tras la realización de este proyecto y sobre las posibles mejoras, terminando con una demostración del funcionamiento del equipo en la vida real. ABSTRACT. Nowadays, in hospitals and nursing homes it is required to have a patient-nurse care system. This system must be able to control and manage each one of the alarms, in the shortest possible time and with maximum efficiency. For this, we have designed a complete solution called ConnectCare. The system architecture is modular and the communication is by IP protocol. This allows the system to adapt to each situation and providing specific solutions. This system is composed by a software, called Buslogic, which it manages the alarms in the PC server and a hardware, called Fonet Control TCP / IP, which it has a dual role: the first role, it is a telephone intercom device and second role, it is a system alarm manager and it can control some external devices. As telephone intercom device, it is integrated into the telephone network and also it is an analog extension terminal allowing intercommunication between the patient and the health personnel. A short description of this intercommunication system will be made, because it is not the subject of this project. Otherwise, the control system will be described with more emphasis on the design and operation point of view, because this is the subject of this project. The control board allows the reception of signals from wired devices, such as pushbutton handset or bathroom pullcord. It is also possible to receive warning signals of non nurse call devices such as smoke detectors or motion detectors. Moreover, it allows to control the lights of the patients’ rooms and to act on other external devices. Then, a budget will be showed. The budget is divided into two parts, the first one is related with the design of the control board and the second one corresponds to the serial production of it. Then, it is discussed the conclusions of this project and the possible improvements, ending with a demonstration of the equipment in real life.

Latitudinal variation in the planktic foraminifer Contusotruncana contusa in the terminal Cretaceous ocean

The morphological variability (coiling properties, size and shape) of the planktic foraminifer Contusortuncana contusa (Cushman) in the terminal Cretaceous ocean was examined at eight deep-sea sites and two continental sections from low (16°) to middle (42°) paleolatitudes in both hemispheres. The material used in this study includes samples from the South Atlantic (DSDP Sites 356, 527 and 525A), North Atlantic (Sites 384 and 548A), Indian and Pacific Oceans (DSDP Site 465A and ODP Sites 761C and 762C) and Tethyan Ocean (outcrop sections from El-Kef and Caravaca). On average 45 specimens from two samples per location were analysed, from an interval corresponding approximately to the last 60 kyr of the Cretaceous. No differences in coiling direction (dextral proportions were > 90% in all samples), percentage of kummerform specimens (usually > 50%) and number of chambers in the last whorl (4-5) were observed between the sites. Both test size (expressed as spiral outline area and test volume) and total number of chambers increase significantly towards lower latitudes. Similarly, test conicity, examined by shape coordinate and eigenshape methods, and angularity of the spiral outline show a rather continuous, slight increase towards lower latitudes. Kummerform specimens of C. contusa were slightly larger and more conical than normalforms and possessed substantially more chambers (both totally and in the last whorl). A principal components analysis of the sample means of five variables describing size and shape clearly distinguished high-latitude sites (525A, 527, 548A, 761C and 762C) from low-latitude sites (384, 465A, Caravaca and El-Kef). Specimens from Site 356 are transitional with respect to those two groups. The results indicate: (1) considerable morphological variation in C. contusa during the terminal Cretaceous comparable to that known in many Recent planktic foraminiferal species and (2) a geographical distribution of this variation corresponding to previously suggested biogeographic schemes based on quantitative analysis of planktic foraminiferal assemblages. Despite the differences in sample means, the overall morphology of C. contusa overlaps among the sites studied, supporting the classification of all C. contusa morphotypes as a single species. Similarly, no discrete morphologic groups could be distinguished within any of the samples.

An investigation of contaminant distribution in subsurface marine wood waste at Mill-A South Terminal, Port of Everett, Washington

This project investigates the correlation between contaminants and the wood waste present in marine sediments off the shore of the Port of Everett in the former Weyerhaeuser Mill-A pulp mill site. The investigation includes the results of two field studies, which tested contaminant levels in 22 boreholes as well as several surface samples. The contaminants include heavy metals and wood waste byproducts. These results, along with 14 other bore logs, provide the framework for a three-dimensional site model, interpolating the full extent of the depositional units and organic and inorganic chemicals found at Mill-A. The sediments of interest are divided into five depositional units defined by the percent wood content and type of wood: native material (<5% wood), intermediate (<30% wood), sawdust (<30% wood), woodchips (<30% wood), and poorly sorted sands with silt (SM-SP) (0% wood). The contaminants include arsenic, 2,4-dimethylphenol, and total organic carbon. Three-dimensional modeling software, RockWorks, interpolated the discrete borehole data of sediment and contaminants assuming horizontal continuity between sampling locations. The sediment distribution was calculated within concentration ranges for each contaminant of concern. The lowest detection limits, the screening levels, and the cleanup levels defined these ranges. Total organic carbon served as a proxy to estimate the quantity of wood waste in the sediment. As a known byproduct of wood decomposition, 2,4-dimethylphenol was expected to be more prevalent in the depositional units with more wood waste. Finally, arsenic was a proxy for other contaminants to determine if contaminants at Mill-A are dominant in sediments with high percentages of wood waste. The volumetric distribution established that high levels of total organic carbon are present in the sediment with higher percentages of wood waste. This correlation was stronger in the decomposing sawdust-rich sediment than the woodchip-rich sediment. The 2,4-dimethylphenol concentrations above cleanup standards were dominant in the sawdust-rich, intermediate and native sediments. Concentrations of 2,4-dimethylphenol below cleanup levels characterized the native sediment. The distribution of arsenic showed no statistically significant correlation to wood content in sediment. These results do not support the hypothesis of contaminant-rich wood waste, as many of the high concentrations of contaminants were not in the wood-rich sediments. This suggests that the contaminants are more distributed among all depositional units at Mill-A rather than focused within sediments with a high percent of wood waste. Understanding the distribution of potentially toxic compounds with wood waste is important for restoring the Puget Sound waterways to a more habitable environment. Future studies should include new data to validate these results and to limit the uncertainty of the extent of contaminants. Future studies may also find motive in looking for a correlation between contaminants and grain size based on previous studies linking these characteristics. These investigations will benefit the current cleanup effort as well as future cleanup efforts at similarly contaminated waterways.

Living with Terminal Capitalization Rates: A Look at Real Estate Valuation Model Parameter Setting

This paper examines assumptions about future prices used in real estate applications of DCF models. We confirm both the widespread reliance on an ad hoc rule of increasing period-zero capitalization rates by 50 to 100 basis points to obtain terminal capitalization rates and the inability of the rule to project future real estate pricing. To understand how investors form expectations about future prices, we model the spread between the contemporaneously period-zero going-in and terminal capitalization rates and the spread between terminal rates assigned in period zero and going-in rates assigned in period N. Our regression results confirm statistical relationships between the terminal and next holding period going-in capitalization rate spread and the period-zero discount rate, although other economically significant variables are statistically insignificant. Linking terminal capitalization rates by assumption to going-in capitalization rates implies investors view future real estate pricing with myopic expectations. We discuss alternative specifications devoid of such linkage that align more with a rational expectations view of future real estate pricing.

Terminal defect analysis and classification methodology for automotive industry

The impact of end customer quality complaints with direct relationship with automotive components has presented negative trend at European level for the entire automotive industry. Thus, this research proposal is to concentrate efforts on the most important items of Pareto chart and understand the failure type and the mechanism involved, link and impact of the project and parameters on the process, ending it with the development of one of the company’s most desired tool, that hosted this project – European methodology of terminals defects classification, and listing real opportunities for improvement based on measurement and analysis of actual data. Through the development of terminals defects classification methodology, which is considered a valuable asset to the company, all the other companies of the YAZAKI’s group will be able to characterize terminals as brittle or ductile, in order to put in motion, more efficiently, all the other different existing internal procedures for the safeguarding of the components, improving manufacturing efficiency. Based on a brief observation, nothing can be said in absolute sense, concerning the failure causes. Base materials, project, handling during manufacture and storage, as well as the cold work performed by plastic deformation, all play an important role. However, it was expected that this failure has been due to a combination of factors, in detriment of the existence of a single cause. In order to acquire greater knowledge about this problem, unexplored by the company up to the date of commencement of this study, was conducted a thorough review of existing literature on the subject, real production sites were visited and, of course, the actual parts were tested in lab environment. To answer to many of the major issues raised throughout the investigation, were used extensively some theoretical concepts focused on the literature review, with a view to realizing the relationship existing between the different parameters concerned. Should here be stated that finding technical studies on copper and its alloys is really hard, not being given all the desirable information. This investigation has been performed as a YAZAKI Europe Limited Company project and as a Master Thesis for Instituto Superior de Engenharia do Porto, conducted during 9 months between 2012/2013.
