Analisis numérico 2D y 3D del ataque sulfático externo en hormigón

UPCommons - dv., 12/07/2018 - 22:24
Analisis numérico 2D y 3D del ataque sulfático externo en hormigón Vélez Posada, Álvaro Hernando La degradación por ataque sulfático externo en hormigón se genera tras la entrada de iones sulfato que se difunden por los poros de la pasta de cemento. Los iones se combinan con la portlandita existente en la pasta creando yeso, y éste con los aluminatos también presentes en la pasta hidratada, precipitando etringita secundaria que causa expansiones volumétricas con la subsiguiente fisuración que a su vez acelera la entrada de sulfatos y la degradación del material.

Implementation and integration of an experimental vehicle sensor setup for automated parking

UPCommons - dv., 12/07/2018 - 22:06
Implementation and integration of an experimental vehicle sensor setup for automated parking Linares, Alberto This thesis has been realized for the automotive engineering department of the TU-Darmstadt University. This department is currently carrying out research in the field of sensor modeling to support autonomous driving. During this thesis the main objective is the rear sensors Bosch parkpilot URF7 implementation and integration, using the methodology described by the thesis. Besides, part of the results obtained have been used for the modeling of ultrasonic sensors for valet parking use cases. The thesis is divided in different stages. First of all, a documented bibliographic search will be carried out on the ultrasonic sensors general operation and the different most important technical specifications of an ultrasonic sensor in the field of the automotive industry as well. Among them are: the field of view, detectable objects distance ranges and accuracy of the measurement. Once the necessary information for the thesis has been obtained, the Bosch Parkpilot URF7 has been used and the different tests previously described in the methodology research have been elaborated. Besides, imparting of the initial methodology extra tests have been made based on the calculation of the distance between sensor and object in real time. It should be noted that all these tests have been run without the sensor setup installation in the car. In contrast, the position and orientation of the sensors has been fixed as in the institutes test vehicle, Honda Accord, thanks to a movable platform. Once the system has been installed and powered with an external power supply, the basic functionality as an user level has been checked, in other words, the system calibration and the operating mode. To get a better understanding of the operation, the board that controls the Bosch sensor setup has been examined. The actual functioning of the existing hardware could not be found successfully due to the lack of information from the manufacturers. However, it is known the existence of a communication between sensors and the control unit, so that, with the realization of different tests and observing its signal with a DAQ, the signals can be read an processed. Once the operation of this Bus has been checked, the different experiments are performed to determine some technical specifications of the sensors: the field of vision (both of a sensor and of the entire sensor setup), the distance range in which a object can be detected, the operation of the cross echo and the accuracy in the measurement. Finally, with an Arduino UNO the signal of the communication bus has been processed to obtain the distance to an object as accurate as possible in real time. In addition, the sensitivity of the results obtained with the Arduino will also be determined.

Automation of processes in forensic analysis

UPCommons - dv., 12/07/2018 - 21:54
Automation of processes in forensic analysis Jubany Ticó, Marc Historically, the nature of cybercrime has evolved systematically with advances in computer technology. Due to the complex nature of forensic investigations, it is essential to have adequate methodologies and tools that organize and automate the execution of tasks, reducing the error space during the process and, at the same time, providing a disciplinary framework that provides greater possibilities for the evidence to be admitted in a judicial process. As a result of the constant transfer of information that occurs electronically, the use and presentation of electronic mails as evidence in a litigation has been common for a long time. The current Civil Procedure Law (LeC2000) admits the validity of the electronic evidence provided by any of the parties, as long as they are not challenged by the opposing party. That is why, in order for an email to be accepted by the courts, and the opposing party can not challenge it, a study must be carried out by experts in the field -computer experts- who will base their report on the examination, both of the machine that contains it, as well as the program in which it is hosted, as well as of the additional digital information provided by the mail message itself, which unmistakably demonstrates the validity of this electronic message. As a result of this context, the author of this project has decided to proceed with the adveration or coherence analysis of emails. During this work, and thanks to the experience gained during years in the cybersecurity company INCIDE, a methodology and a series of scripts have been developed to obtain this end; to be able to adverate an email in a consistent way.; Históricamente, la naturaleza de los delitos informáticos ha evolucionado de forma sistemática con los avances de la tecnología informática. Debido al carácter complejo de las investigaciones forenses, es esencial contar con metodologías y herramientas adecuadas que organicen y automaticen la ejecución de tareas disminuyendo el espacio de errores durante el proceso y al mismo tiempo, proveyendo un marco de trabajo disciplinario que otorga mayores posibilidades para que la evidencia sea admitida en un proceso judicial. Fruto del constante trasiego de información que se produce por vía electrónica, desde hace ya tiempo es muy común el uso y presentación de correos electrónicos, como prueba en un litigio. La actual Ley de Enjuiciamiento Civil (LeC2000) admite la validez de las pruebas electrónicas aportadas por cualquiera de las partes, siempre que éstas no sean impugnadas por la parte contraria. Es por eso que, para que un correo electrónico sea aceptado judicialmente, y la parte contraria no lo pueda impugnar, debe hacerse un estudio por parte de expertos especialistas en la materia -los peritos informáticos-, que basarán su informe en el examen, tanto de la máquina que lo contiene, como del programa en el que este está alojado, así como de la información adicional digital que suministra el propio mensaje de correo, que acredite de forma inconfundible la validez de este mensaje electrónico. A raíz de este contexto, el autor de este trabajo ha decidido procedimentar la adveración o análisis de coherencia de correos electrónicos. Durante este trabajo, y gracias a la experiencia obtenida durante años en la empresa de ciberseguridad INCIDE, se ha desarrollado una metodología y una serie de scripts, para obtener este fin; poder adverar un correo electrónico de forma consistente.; Històricament, la naturalesa dels delictes informàtics ha evolucionat de forma sistemàtica amb els avenços de la tecnologia informàtica. A causa del caràcter complex de les investigacions forenses, és essencial comptar amb metodologies i eines adequades que organitzin i automatitzin l'execució de tasques disminuint l'espai d'errors durant el procés i al mateix temps, proveint un marc de treball disciplinari que atorga més possibilitats perquè l'evidència sigui admesa en un procés judicial. Fruit del constant tràfec d'informació que es produeix per via electrònica, des de fa ja temps és molt comú l'ús i presentació de correus electrònics, com a prova en un litigi. L'actual Llei d'enjudiciament civil (LeC2000) admet la validesa de les proves electròniques aportades per qualsevol de les parts, sempre que aquestes no siguin impugnades per la part contrària. És per això que, perquè un correu electrònic sigui acceptat judicialment, i la part contrària no ho pugui impugnar, s'ha de fer un estudi per part d'experts especialistes en la matèria -els pèrits informàtics-, que basaran el seu informe en l'examen, tant de la màquina que el conté, com del programa en què aquest està allotjat, així com de la informació addicional digital que subministra el mateix missatge de correu, que acrediti de forma inconfusible la validesa d'aquest missatge electrònic. Arran d'aquest context, l'autor d'aquest treball ha decidit procedimentar l'adveració o anàlisi de coherència de correus electrònics. Durant aquest treball, i gràcies a l'experiència obtinguda durant anys a l'empresa de ciberseguretat INCIDIE, s'ha desenvolupat una metodologia i una sèrie de scripts, per obtenir aquest fi; poder adverar un correu electrònic de forma consistent.

Spectroscopic characterization of Er3+, Yb3+ co-doped UC single crystals : the influence of host and sensitizer concentrations

UPCommons - dv., 12/07/2018 - 21:45
Spectroscopic characterization of Er3+, Yb3+ co-doped UC single crystals : the influence of host and sensitizer concentrations Saleta Reig, David The energy transfer upconversion (ETU) mechanism is known to be the most efficient route for the conversion of near infrared (NIR) light to visible emission in Ln3+-co-doped systems. In this work, we examined these energy transfer (ET) processes in Yb3+,Er3+-co-doped fluoride single crystals. Because of their low phonon energy, high thermal dissipation, chemical stability and high transmission in the ultraviolet, visible, and NIR, these materials are ideal systems to study such processes. Here, we focus on the influence of the concentration of the sensitizer Yb3+ on the optical and upconversion properties of three different fluoride hosts doped with Yb3+ and Er3+ as a function of excitation power density and compare direct Ln3+-excitation and excitation in the NIR via ET.

CO2 addition to increase biomass production and control microalgae species in high rate algal ponds treating wastewater

UPCommons - dv., 12/07/2018 - 17:00
CO2 addition to increase biomass production and control microalgae species in high rate algal ponds treating wastewater Uggetti, Enrica; Sialve, Bruno; Hamelin, Jérôme Challenges regarding microalgal cultivation need to be solved in order to enhance microalgae potential as a feedstock for biofuel, bioenergy, and bioproducts. The optimization of the operating strategy in high rate algal ponds treating wastewater still requires research on microalgal ecosystem response to variations in nutrients availability. For this reason, the aim of this study was to determine the effect of CO2 addition on microalgal population diversity and wastewater treatment performance. To this end, batch and continuous experiments were carried out in an experimental plant constituted by four high rate algal ponds (500 L each) treating urban wastewater with and without pH regulation. As expected, CO2 addition induced a significant increase in biomass concentration (between 66 and 100%). Moreover, a positive effect on microalgal biomass concentration was observed, reducing the effect of the variation in influent wastewater characteristics. Concerning the microalgal populations, the variation of inorganic carbon availability induced a shift in the dominant microalgae species. In spite of this, no variations were observed in terms of wastewater treatment efficiency. Taking together, this study highlighted the positive effect of CO2 addition to increase biomass production and control microalgae species in high rate algal ponds treating wastewater.

Coincident observations by the Kharkiv IS radar and ionosonde, DMSP and Arase (ERG) satellites, and FLIP model simulations: implications for the NRLMSISE-00 hydrogen density, plasmasphere, and ionosphere

UPCommons - dv., 12/07/2018 - 13:15
Coincident observations by the Kharkiv IS radar and ionosonde, DMSP and Arase (ERG) satellites, and FLIP model simulations: implications for the NRLMSISE-00 hydrogen density, plasmasphere, and ionosphere Kotov, Dmytro; Richards, Philip G.; Truhlík, Vladimír; Hernández Pajares, Manuel This paper reports the results of ionosphere and plasmasphere observations with the Kharkiv incoherent scatter radar and ionosonde, Defense Meteorological Satellite Program, and Arase (ERG) satellites and simulations with field line interhemispheric plasma model during the equinoxes and solstices of solar minimum 24. The results reveal the need to increase NRLMSISE-00 thermospheric hydrogen density by a factor of ~2. For the first time, it is shown that the measured plasmaspheric density can be reproduced with doubled NRLMSISE-00 hydrogen density only. A factor of ~2 decrease of plasmaspheric density in deep inner magnetosphere (L ˜ 2.1) caused by very weak magnetic disturbance (Dst > 22 nT) of 24 December 2017 was observed in the morning of 25 December 2017. During the next night, prominent effects of partially depleted flux tube were observed in the topside ionosphere (~50% reduced H+ ion density) and at the F2-layer peak (~50% decreased electron density). The likely physical mechanisms are discussed.

Sustainable house project in Jeddah, Saudi Arabia

UPCommons - dc., 12/05/2018 - 19:31
Sustainable house project in Jeddah, Saudi Arabia Rayes, Albaraa Ayman M Most of the Arab countries, Including the Kingdom of Saudi Arabia, are located between the orbit of Capricorn and Cancer, which is called the hot climate countries. The temperature in these countries is higher than any other region in the world. The relative humidity varies between the low (dry weather) and high (humid weather). This climate affects the nature life of this area which requires the attempt to deal with differents aspects, especially in the field of architecture and urban planning. In the past decades, special procedures and methods have been proven to be successful for climate treatment both at the level of the small residential unit and at the urban level in rural or urban areas. The steady increase in the volume of construction in this area led to use the assistance of experts in engineering and architecture from the developed countries. These experts took into consideration the climate conditions and the preservation of the local architecture style. However, the blind copying of the local architects distorted the architectural style. The fact that they did not take into consideration the climate treatments caused these distortions. As a result, the new architectural style was based meanly on the technology to create air ventilation and artificial lighting. As a result, the built structures have placed significant impression on energy use almost 50% of the primary energy in Saudi Arabia. The energy used by the construction division continues to increase. Energy consumption in the commercial and residential buildings sector will continue to grow until buildings can be designed to use energy efficient design methods as well as produce enough energy to offset the growing energy demand of these building. It is imperative to study and research this architecture and to learn from it and extract principles and design guidelines for application in contemporary settings.

Synchronization of traffic flow and sector opening for collaborative demand and capacity balancing

UPCommons - dc., 12/05/2018 - 17:13
Synchronization of traffic flow and sector opening for collaborative demand and capacity balancing Xu, Yan; Prats Menéndez, Xavier; Delahaye, Daniel —This paper proposes a method to synchronize traffic flow optimization and sector opening scheduling, with the aim of achieving flexible demand and capacity balancing (DCB). Delay assignment, trajectory options and sector collapsing are used to manage the traffic demand, while sector opening schemes are to affect the airspace capacity. Mixed Integer Programming (MIP) model is built to incorporate these initiatives. Three model variants are presented to illustrate the synchronization process, and their results in a real-world case study demonstrate some promising improvements for the DCB performances. Index Terms—air traffic flow management, trajectory options, dynamic sectorization, demand and capacity balancing This paper was partially funded by grants from the CSC No 201506830050 and by the SESAR Joint Undertaking under grant agreement No 699338.
