Introducción: La intersexualidad comprende condiciones infrecuentes donde una persona nace con una anatomía sexual diferente del binario hombre-mujer; esto supone habitar un cuerpo fuera de lo inteligible y estigmatizado. Históricamente, desde la heteronorma, el modelo biomédico ha buscado normalizarles quirúrgicamente para asignar precoz y arbitrariamente un sexo-género armónico con la genitalidad. Desde los Derechos Humanos, estas prácticas son cuestionadas por colectivos Intersex. Materiales y método: Estudio de caso, entre años 2019 y 2020; técnica de entrevista en profundidad a dos usuarios adultos de los Policlínicos de Urología y Endocrinología de un hospital público en Santiago, Chile; se utilizó la fenomenología de Husserl para comprender la experiencia en el sistema de salud de las personas intersex. El análisis de la información se basó en la propuesta de Colaizzi. Resultados: Se reconocieron unidades de significado principales e imbricadas, cuyas esencias permitieron describir el fenómeno de: ser niño y habitar el espacio hospitalario, vivir con la condición actualmente, y la experiencia de utilizar el sistema de salud siendo adulto. Conclusiones: Se identificaron diversas estrategias de agencia tanto en el espacio hospitalario como el cotidiano, mediante un proceso personal y silencioso de aprendizajes sobre las implicancias de ser intersexual., Introduction: Intersexuality includes extremely rare conditions where a person is born with a sexual anatomy different from the male-female binary; this supposes inhabiting a body outside the intelligible, configuring a stigma. Historically and from the heteronorm, the biomedical model has sought to surgically normalize them in order to precociously and arbitrarily assign a gender in harmony with genitality. From Human Rights, these practices have been questioned by Intersex groups. Materials and method: During the years 2019 and 2020, case studies were carried out through in-depth interviews with two adult users of the Urology and Endocrinology Polyclinics of a public hospital at Santiago, Chile; Husserl's phenomenology was used to visualize the phenomenon according to how it is experienced by the subjects who carry it, using the procedure described by Colaizzi as an information analysis plan. Results: Main and overlapping units of meaning were recognized, whose essences allowed describing the phenomenon of: being a child and inhabiting the hospital space, currently living with the condition, and the experience of using the health system as an adult, with new and own meanings. Conclusions: Various agency strategies were identified both in the hospital space and in everyday life, through a personal and silent process of learning about the implications of being intersex., Introdução: Intersexo compreende condições raras em que uma pessoa nasce com uma anatomia sexual diferente do binário masculino-feminino; Isso significa habitar um corpo fora do que é inteligível e estigmatizado.

Leading cybersecurity agencies and standardization bodies have globally emphasized the critical need to transition towards Post-Quantum Cryptography (PQC) to defend against emerging quantum computing threats. They advocate PQC as a practical and cost-effective solution for security systems nowadays. Nevertheless, emerging technologies such as industrial systems, e.g., autonomous vehicles, air traffic management, diagnostic imaging machines, etc., and robotics systems, e.g., ROS2 (Robotic Operating System), have not started their evolution to enhance crypto-agility and security robustness. Some of these emerging technologies use the Data Distribution Service (DDS) standard as the underlying communication middleware protocol. DDS is a distributed publish-subscribe system that allows sending and receiving data by publishing and subscribing to topics across a network of connected nodes. However, DDS’s security is based on traditional symmetric and asymmetric cryptography, which is vulnerable to quantum computing attacks. To address this issue, we propose the integration of PQC into DDS, through the development of a C/C++ library, called pqsec-dds, which can be integrated across different DDS implementations such as CycloneDDS or OpenDDS. A proof-of-concept demonstrates the viability of our approach in enhancing the security and cryptoagility of DDS-based systems

Tesi amb menció internacional, (English) With the development of industry and society, new verticals have emerged such as Industry 4.0, cooperative sensing, and massive IoT. These verticals require network robustness and availability to maintain high levels of QoS, just as 5G and beyond networks must guarantee to the end-users. In this regard, several technologies have been identified by network operators and academic institutions as crucial pillars in deploying these networks. More specifically, due to their advantages, SDN, NFV, and MEC are likely to make the deployment of 5G and beyond networks easier for operators. Nevertheless, network resilience and robustness are not guaranteed using these technologies. The literature addressing resilient and fault-tolerant strategies is focused on proposing unique mechanisms to be applied in each of the above paradigms. Furthermore, the proposed approaches are mainly related to communication mechanisms used in distributed domains to improve network scalability and resilience. Thus, they lack other perspectives and factors that can also impact the robustness and fault tolerance of the network, such as the VNF allocation in resource-constrained environments. This thesis therefore focuses on designing and implementing novel strategies to improve network resilience and fault tolerance in SDN/NFV environments through communication and event-allocation approaches. In particular, the proposed communication mechanism, different from existing related works, guarantees network information exchange among control elements of both systems. This proposal enables auto-discovery and failure awareness, thus ensuring the necessary dynamism in the next-generation networks. Additionally, the control elements can improve their decision-making process by considering information external to the region controlled by them. Then other controllers’ control and management policies, such as load-balancing methods, can be improved by considering this newly available information. This, (Català) Amb el desenvolupament de la indústria i la societat, nous serveis han sorgit com ara la Indústria 4.0, la detecció cooperativa i l'IoT. Aquests serveis requereixen robustesa i disponibilitat de la xarxa per mantenir alts nivells de QoS, justament el que les noves generacions de xarxes han de garantir als usuaris. En aquest sentit, tecnologies com SDN, NFV i MEC han estat identificades com a pilars en el desplegament d'aquestes xarxes a causa dels avantatges que ofereixen. Tot i això, la resiliència i la tolerància a fallades no estan garantides amb aquestes tecnologies. La literatura que aborda estratègies resilients i tolerants a fallades s'enfoca a proposar mecanismes per ser aplicats a cadascun dels paradigmes anteriors. A més, els seus enfocaments estan relacionats amb els mecanismes de comunicació utilitzats en dominis distribuïts per millorar l'escalabilitat i la resiliència de la xarxa. Per tant, no tenen altres factors que també poden afectar la solidesa i la tolerància a fallades de la xarxa, com l'assignació de VNFs en entorns amb recursos limitats. Per tant, aquesta tesi s'enfoca a dissenyar i implementar noves estratègies per millorar la resiliència i la tolerància a errors en entorns SDN/NFV mitjançant mecanismes de comunicació i assignació d'esdeveniments. Específicament, el mecanisme de comunicació proposat, contrari a treballs existents, garanteix l'intercanvi d'informació de xarxa entre els controladors de tots dos sistemes. Aquesta proposta permet l'autodescobriment i la detecció de fallades, assegurant així el dinamisme necessari a les noves generacions de xarxes. Addicionalment, els elements de control poden millorar les seves decisions en considerar informació externa a la regió que ells controlen. Així, les polítiques de control i gestió d'altres controladors, com els balancejadors de càrrega, es poden millorar en considerar aquesta informació disponible.

The delivery of drugs is a great challenge, since most of active pharmaceutical ingredients developed today are hydrophobic and poorly water soluble. From this perspective, drug encapsulation on biodegradable and biocompatible polymers can surpass this problem. Poly(gamma-glutamic acid) (PGGA), a bioedible and biocompatible polymer has been chosen for this purpose. Carboxylic side groups of PGGA have been partially esterified with 4-phenyl-butyl bromide, producing a series of aliphatic–aromatic ester derivatives with different hydrophilic–lipophilic balances. Using nanoprecipitation or emulsion/evaporation methods, these copolymers were self-assembled in a water solution, forming nanoparticles with average diameters between 89 and 374 nm and zeta potential values between -13.1 and -49.5 mV. The hydrophobic core containing 4-phenyl-butyl side groups was used for the encapsulation of an anticancer drug, such as Doxorubicin (DOX). The highest encapsulation efficiency was reached for a copolymer derived from PGGA, with a 46 mol % degree of esterification. Drug release studies carried out for 5 days at different pHs (4.2 and 7.4) indicated that DOX was released faster at pH 4.2, revealing the potential of these nanoparticles as chemotherapy agents., Peer Reviewed, Postprint (published version)

Many modern applications need to run on massively interconnected sets of heterogeneous nodes, ranging from IoT devices to edge nodes up to the Cloud. In this scenario, communication is often implemented using the publish-subscribe paradigm. The Data Distribution Service (DDS) is a popular middleware specification adopting such a paradigm. The DDS is becoming a key enabler for massively distributed real-time applications, with popular frameworks such as ROS 2 and AUTOSAR Adaptive building on it. However, no formal modeling and analysis of the timing properties of DDS has been provided to date. This paper fills this gap by providing an abstract model for DDS systems that can be generalized to any implementation compliant with the specification. A concrete instance of the generic DDS model is provided for the case of eProsima’s FastDDS, which is eventually used to provide a real-time analysis that bounds the data-delivery latency of DDS messages. Finally, this paper reports on an evaluation based on a representative automotive application from the WATERS 2019 challenge by Bosch.

Introduction: 5 alpha reductase deficiency is a rare disease that produces alterations in sexual development whose prevalence is unknown but has been described in popula-tions with common genealogy in areas of the Dominican Republic, Turkey, Lebanon and Papua New Guinea. Material and methods: We present a preschool patient who attends a review consultation due to the presence of masses in bilateral labia majora and slight growth of the clitoris since birth from an area in the south of the country known to present cases of abnormalities of sexual differen-tiation due to 5 alpha reductase deficiency. Female-looking external genitalia, bilateral 2ml masses in the labia majora, 2cm clitoris with slight hypertrophy and vaginal introitus. Karyotype, baseline testosterone and dihydrotestoste-rone determinations, as well as sonographic studies were performed. Dihydrotestosterone gel at 0.2 mg/kg daily was applied to the genital area for 4 months prior to surgery. Results: The karyotype was 46xy. Testosterone/Dihydro-testosterone ratio: 41.25 Genital ultrasound: 2 structures with characteristics of testicles with preserved dimen-sions and morphology. masculinizing genitoplasty was performed. After 4 months of daily application of the preparation, a longitudinal growth of the phallus of 4.5 cm and a circumference of 4 cm were confirmed. Conclusion: Reconstruction or genitoplasty at an early age offers better results with the prior application of local dihydrotestosterone., Introducción: la deficiencia de 5 alfa reductasa es una enfermedad rara que produce alteración en el desarrollo sexual y cuya prevalencia se desconoce, pero que ha sido descrita en poblaciones con genealogías comunes en áreas de la República Dominicana, Turquía, Líbano y Papúa Nueva Guinea Material y métodos: presentamos un paciente prees-colar que acude a consulta de revisión por presencia de masas en labios mayores bilaterales y ligero crecimiento del clítoris desde el nacimiento; procedente de un área del sur del país, conocida por registrar casos de anomalías de la diferenciación sexual por déficit de 5 alfa reductasa.

Conclusión: la reconstrucción o genitoplastia a edades tempranas ofrece mejores resultados con la aplicación previa de dihidrotestosterona local.

One of the treatments for cancer is chemotherapy but most anticancer drugs have a low therapeutic index, which causes toxicity complications in the healthy tissues [1]. To minimize these complications and improve the effect of the existing drugs, drug delivery by nanoparticles have drawn more attention as they are easy to produce and can also be prepared through biocompatible polymers [2]. Here, we report the preparation of polymer nanoparticles derived from esters of poly(¿-glutamic acid) which could be able to encapsulate hydrophobic drugs that can be used as drug delivery systems (DDS) for the treatment of different tumours. In this work, PGGA has been modified in order to improve its solubility in organic solvents and its processing capacity of this water-soluble polymer. Due to the fact that most of the anticancer drugs are lipophilic, the hydrophobic modification of PGGA will enhance the drug encapsulation., Postprint (published version)

The Ship Integration Program Office (PMW760) is interested in the prospect of having a unified, cohesive communications protocol that can be used by all unmanned systems under their purview. The Data Distribution Service (DDS) is a prime candidate for such cohesive communications using point-to-point links. The objective of this thesis is to assess the performance of DDS in a network architecture that fits the naval use case criteria. We propose a network architecture that incorporates Satellite Communications (SATCOM) and Wireless Fidelity (WiFi) links to test the ability of DDS to execute cohesive communications between the network nodes within constraints of the scenario setup. We use a network emulator, Mininet, to set up the network parameters and investigate the throughput and latency performance of the individual point-to-point links across various data sample sizes. Simulations are conducted to measure throughput and latency under different network configurations (Ideal, Jitter and Multi-Flow) using the Real-Time Innovation Perftest software tool. For the Ideal and Jitter configurations, the simulations are performed for RELIABLE and BEST EFFORT communications as well as with and without implementation of DDS security. We also conduct simulations in the Multi-Flow configurations to evaluate how simultaneous multi-flow data (traffic data running in parallel within the network nodes) contend for the network resources and impact performance., Major, Republic of Singapore Navy, Approved for public release. distribution is unlimited

Personalized or individualized medicine is considered as an innovative approach to deliver the right dose to the right person at the right time. However, current technologies producing pharmaceutical products do not address the growing need for these new therapies. The aim of this work was the preparation of long-acting implantable dosage forms in which the drug release is regulated by the polymer matrix and the design of the implant. Paliperidone palmitate (PP), was selected as model drug. Indeed, PP is sensitive to thermal degradation above its melting temperature and its amorphous state remains difficult to obtain and stabilize. The first part of this study focused on obtaining and stabilizing the amorphous form of PP. A ternary mixture based on two polymers was therefore selected to be printed as dosage forms. Following an in vitro dissolution test, different release profiles were obtained depending on the selected printing parameters. Then, the stability of the amorphous state of PP was assessed at two different temperatures. During this test, implants were placed at 4°C and 25°C ± 40% residual humidity for 3 months. In the 2nd part, a 3D printing technology reducing the number of steps required to produce a suitable formulation was studied. This technology was based on a pressure extrusion-based printing process. Polycaprolactone was chosen as biocompatible and bioresorbable polymer matrix. Two different designs have been studied, namely a ring and a disk. The goal was to compare the effect of the design on the release of PP. An in vitro dissolution test was performed over a period of 3 to 6 months. In the last part, the development of a proof of concept of a predictive model taking into account the design of the printed form was studied. The impact of different printing parameters on the drug release were studied through a Design of Experiments (DoE). Finally, a second DoE was used to predict the release of PP from complex dosage forms combining two formulati, Doctorat en Sciences biomédicales et pharmaceutiques (Pharmacie), info:eu-repo/semantics/nonPublished

Thèse réalisée dans le cadre d'une collaboration avec UCB Pharma et la région Wallonne s'inscrivant dans le cadre du projet SAS. Le but de ce projet était de développer des implants sous-cutanés imprimés en trois dimensions pour permettre une libération d’anticorps thérapeutique de manière prolongée au cours du temps. En effet, les thérapies disponibles sont souvent administrées par voie intraveineuse, ce qui peut réduire la compliance des patients dû à l’inconfort et à la fréquence de ces administrations. Les systèmes de délivrance, tels que des implants, peuvent limiter les fréquences d’administration grâce à l’insertion d’un dispositif qui libèrera le principe actif au cours du temps durant une période donnée. Les implants s’inscrivent comme une alternative aux microsphères qui sont également des dispositifs développés et investigués en vue de favoriser l’adhésion et la compliance des patients. L’avènement du 3D dans le milieu pharmaceutique a montré une certaine frénésie liée au développement de la médecine personnalisée et à l’innovation du procédé dans ce secteur. La sélection d’un matériau biocompatible et biorésorbable tel que le PLGA représente une véritable plus-value dans le développement d’implant. Etant donné que ces implants sont biodégradables, le retrait n’est pas à envisager, ce qui limite les désagréments du patient à un seul acte chirurgical lors de l’implantation. Au cours de ce travail, une approche pragmatique a d’abord été abordée sur les procédés d’extrusion à chaud et de l’impression 3D en utilisant un polymère couramment employé dans l’impression grand public, le PLA. L’investigation des paramètres d’impressions (température d’impression, epaisseur de couche et vitesse d’impression) et l’usage de divers plastifiants (la triacétine (TA), le polyethylène glycol 400 (PEG 400), le citrate de triéthyle (TEC) et l’acétyle citrate de triéthyle (ATEC)) pour faciliter les procédés à chaud et dans l’idée de réduire les températures d’extrusion et d’i, Doctorat en Sciences biomédicales et pharmaceutiques (Pharmacie), info:eu-repo/semantics/nonPublished

The Data Distribution Service (DDS) is a flexible, decentralized, peer-to-peer communication middle-ware. This thesis presents a performance analysis of the DDS usage in the Toyota Smartness platform that is used in Toyota’s Autonomous Guided Vehicles (AGVs). The purpose is to find if DDS is suitable for internal communication between modules that reside within the Smartness platform and for external communication between AGVs that are connected in the same network. An introduction to the main concepts of DDS and the Toyota Smartness platform architecture is given together with a presentation of some earlier research that has been done in DDS. A number of different approaches of how DDS can be integrated to the Smartness platform are explored and a set of different configurations that DDS provides are evaluated. The tests that were performed in order to evaluate the usage of DDS are described in detail and the results that were collected are presented, compared and discussed. The advantages and disadvantages of using DDS are listed, and some ideas for future work are proposed.

Вступ. У традиційному вигляді, програмно-визначена радіосистема (Software Defined Radio, SDR) являє собою обчислювальне ядро, обладнане приймально-передавальними блоками. З метою прискорення обчислювальних операцій у системах SDR, пропонується у якості математичної основи застосування системи залишкових класів. Результати попередніх досліджень, що проводились різними групами вчених з метою пошуків шляхів підвищення продуктивності обчислювальних засобів, методів організації ефективної системи виявлення та виправлення помилок, а також побудови надійних обчислювальних комплексів, дають можливість стверджувати, що в межах позиційних систем числення не можна очікувати принципових зрушень в даних напрямках без суттєвого збільшення робочих частот і ускладнення апаратної частини.. Перевагою пропонованого методу є те, що програмна радіосистема може складатися з декількох ПЛІС і обслуговувати декілька незалежних радіоканалів, а перепрограмування властивостей дозволяє змінювати число і складові процесу обробки повідомлень в залежності від поточних умов роботи. Метод дослідження. В розділі проаналізовано паралельність арифметичні операції у системі залишкових класів. Ці операції називаються модульними, оскільки для обробки числових значень використовують невеликі залишки ділення на певний набір модулів, а для додавання і множення потрібно лише один тактовий цикл роботи обчислювальної системи. Для перетворення чисел із двійкової системи у RNS використовується алгоритм, заснований на застосуванні китайської теореми про залишки. Проте такі операції, як поділ, порівняння двох чисел і виявлення знака, є складними і ресурсозатратними в RNS. Для цих проблемних операцій було запропоновано кілька рішень. Вони полягають у відсутності процесу перетворенні залишку в бінарну систему (зворотне перетворення) шляхом застосування цифро-аналогових перетворювачів у RNS. З іншого боку, вибір правильного набору модулів є ще одним важливим питанням для побудови ефективного RNS з достатнім динамічним

Throughout the Department of Defense, efforts to increase cybersecurity and improve data transfer in unmanned robotic systems (UxS) have been ongoing at warfare centers (NUWC, SPAWAR, etc.) and research facilities (NPS). This thesis explores the performance of the Robot Operating System (ROS) 2, which is built with the Data Distribution Service (DDS) standard as a middleware. Based on how quality of service (QoS) parameters are defined in the robotic middleware interface, it is possible to implement strict delivery requirements to different nodes on a dynamic nodal network with multiple unmanned systems connected. Through this research, different scenarios with varying QoS settings were implemented and compared to baseline values to help illustrate the impact of latency and throughput on data flow. DDS security settings were also enabled to help understand the true cost of overhead and performance when secured data is compared to plaintext baseline values. Our experiments were performed using a basic ROS 2 network consisting of two nodes (publisher and subscriber). Our experiments showed a measurable latency and throughput change between different QoS profiles and security settings. We analyze the trends and tradeoffs associated with varying QoS and security settings. This thesis provides performance data points that can be used to help future researchers and developers make informative choices when using ROS 2 for UxS., http://archive.org/details/qualityofservice1094562809, Lieutenant Commander, United States Navy, Approved for public release; distribution is unlimited.

In this paper, a visible light communication transmitter using a LED matrix with low-cost LEDs is shown. This design use a DAC to control the LED drivers, through a discrete component current mirror circuit. The DAC is controlled using an FPGA, which together works as a highly configurable direct digital synthesiser. The design proposed in this paper is thus well suited as a transmitter node in a software defined radio using visible light communication. In this paper, we describe the design, and show its behaviour when programmed to transmit a number of carriers modulated with amplitude and phase modulation schemes.

Diblock copolymers (PPDLx-b-pPAAy) were prepared from ¿-pentadecalactone and l-glutamic acid or l-lysine amino acids by ring opening polymerization initiated by amino groups. Telechelic amino-ended poly(¿-pentadecalactone) with a length of 15–20 repeating units was firstly synthesized by enzymatic polymerization by means of CALB and then used as macroinitiator for the polymerization of the N-carboxyanhydrides of the two a-amino acids conveniently protected as benzyl and eN-carbobenzoxy derivatives, respectively. The molecular weight of the polypeptide block was accurately controlled by adjusting the amino acid/macroinitiator ratio used in the feed. Copolymers with Mn ranging between ~5000 and ~40,000¿g·mol-1 and varying ester/peptide ratio were obtained and characterized in detail by GPC and NMR spectroscopy. The thermal properties of these copolymers were evaluated by TGA and DSC, and their structure in the solid-state including their response to heating, were examined by FTIR and XRD at variable temperature. It was shown that the polypentadecalactone segment was crystallized for all compositions and that the polypeptide counterpart adopted a two-dimensional hexagonal packing of a-helices at temperatures above melting of the polyester block. SAXS revealed the presence of a biphasic nanostructure with a repeating distance of 27¿nm for the case of glutamic-based copolymers. It was demonstrated that both glutamic and lysine-based PPDLx-b-pPAAy copolymers could self-assemble in well-shaped nanospheres with a diameter in the ~200–400¿nm range and a negative zeta-potential, Peer Reviewed, Postprint (author's final draft)

The latency and flexible requirements of the 5G network are challenging telecommunication operators to have a more flexible, scalable, faster and programmable architecture. To solve this problem, this paper proposes a hybrid hierarchical set of Software Defined Networks (SDN) controllers as the control plane for 5G networks. The architecture is based on a federation of hierarchically-superior controllers which use Data Distribution Service (DDS) to communicate among each other and coordinate multiple sub-network controllers., Peer Reviewed, Postprint (author's final draft)

Aquest projecte consisteix en revisar, caracteritzar i redissenyar si és necessari les diferents parts que componen un prototip biomèdic basat en la tecnologia radar. Mitjançant aquesta tecnologia capaç de detectar moviments és possible monitoritzar constants vitals d'un pacient tals com la respiració o la freqüència cardíaca a partir dels seus desplaçaments toràcics. El radar treballa a alta freqüència (120 GHz) i el sistema s'encarrega de generar el senyal, preparar-lo, transmetre'l i finalment extreure'n informació. El primer capítol del treball és una introducció en la que s'explica el punt de partida: les necessitats del prototip i el primer model que se'n va fer (tot comptant amb la col·laboració de l'Hospital Sant Joan de Déu). En els capítols 2 i 3 es troba una explicació teòrica de les diferents tecnologies implicades: d'una banda una introducció a la tecnologia radar i de l'altra dels diversos components electrònics que conformen aquest disseny. En el quart capítol es tracta la introducció d'un segon canal en el sistema, tot explicant les seves implicacions teòriques, com fer-ne un correcte calibratge i els canvis que això introdueix en el sistema un cop integrat. En el cinquè i en el sisè capítol es revisa, prova i redissenyen dos dels elements principals de la generació de senyal: el DDS i el PLL.

Mediante esta tecnología capaz de detectar movimientos es posible monitorizar constantes vitales de un paciente tales como la respiración o la frecuencia cardíaca a partir de sus movimientos torácicos. El radar trabaja a alta frecuencia (120GHz) y el sistema se encarga de generar la señal, prepararla, transmitirla y finalmente extraer información. El primer capítulo del trabajo es una introducción en la que se explica el punto de partida: las necesidades del prototipo y el primer modelo que se hizo (contando con la colaboración del Hospital Sant Joan de Déu). En los capítulos 2 y 3 se encuentra una explicación teórica de las distintas tecnologías implicadas: por un lado, una introducción a la tecnología radar y por el otro una explicación de los diversos componentes electrónicos que conforman este diseño.

By using this technology capable of detecting movement, it is possible to monitor vital constants of a patient such as the breathing pattern or the cardiac frequency by looking at its thoracic movement. The radar works at a high frequency (120GHz) and the system does generate, prepare and transmit the signal while extracting information from it. The first chapter is an introduction in which the starting point is explained: the need of the prototype and the first model that was built (with the collaboration of Hospital Sant Joan de Déu). In the chapters 2 and 3 a theoretical explanation of the different technologies used is found: on the one hand, an approach to radar technology and on the other hand, a brief explanation of the different electronic components that compose the model. The fourth chapter speaks about the introduction of a second channel in the system and it explains its theoretical implications, how to correctly calibrate them and the changes it produces in the system when integrated. In the fifth and sixth chapter, two of the main elements of signal generation are reviewed, tested and redesigned: the DDS and the PLL. An exhaustive revision from the technical point of view (improvements in its performance, phase noise...) is made, and afterwards its tests and results are presented. In chapter 7, the final results and values of the prototype are summarized and presented as a whole system. In chapter 8 a brief review of the economic impact this project has had is made. Finally, in chapter 9, the main ideas and conclusions reached during the making of this project are presented. Also, some future work that could help the development and improvement of this prototype is proposed.

The aim of the project is to design and develope a signal generator for high resolution CW-FM radars. The signal is a linear FM called chirp. The object of this generator is to be versatile and reconfigurable, in order to be used in different CW-FM radars and keep the resolution and accuracy being a low-spur linear signal. The signal is generated by the direct digital Synthesis (DDS) technique and two prototypes are built in printed circuit board: the first one is realized with CMOS technology and a microcontroller and the second one uses FPGA/CPLD technology, which offers improvements and more flexibility compared to the first one. The project results are positive, as the objectives are achieved and the generator is able to create different chirp waveforms with the syncronism requiered by the radar to acquiere coherent data. Currently, the first prototype is used in the Vital Sense project radar., Este proyecto consiste en diseñar y desarrollar un generador de señal para radares CW-FM de alta resolución. Se trata de una señal FM lineal llamado chirp. El objetivo es que sea versatil y reconfigurable, para poder implementarse en diferentes radares de este tipo, conservando la alta resolución y precisión siendo el señal lineal y libre de espúrios. La señal se genera mediante la síntesis digital directa (DDS) y se realizan dos prototipos del generador en placas de circuito impreso: el primero utilizando tecnología CMOS y un microcontrolador y el segundo con la tecnología FPGA/CPLD, que añade mejoras y flexibilidad respecto el primero. Los resultados del proyecto son positivos, puesto que se logran los objetivos marcados y el generador permite crear diferentes tipos de señal chirp con el sincronismo requerido por los radares para garantizar la coherencia de los datos adquiridos. Actualmente, el primer prototipo se está utilizando en el radar del proyecto Vital Sense., Aquest projecte consisteix en dissenyar i desenvolupar un generador de senyal per a radars CW-FM d'alta resolució. Es tracta d'un senyal FM lineal anomenat chirp. L'objectiu és que el generador sigui versàtil i reconfigurable, per poder implementar-se en diferents radars d'aquest tipus, conservant l'alta resolució i precisió assegurant que el senyal sigui lineal i lliure d'espuris. El senyal es genera amb la síntesis digital directa (DDS) i es realitzen dos prototips del generador en plaques de circuit imprès: el primer utilitzant tecnologia CMOS i un microcontrolador i el segon amb la tecnologia FPGA/CPLD, que afegeix millores i més flexibilitat respecte el primer. Els resultats del projecte són positius, ja que s'assoleixen els objectius i el generador permet crear diferents tipus de senyals chirp amb el sincronisme requerit pels radars per garantir la coherència de les dades adquirides. Actualment, el primer prototip s'està utilitzant en el radar del projecte Vital Sense.

The Direct Digital frequency Synthesizer (DDS) is an architecture largely used for the generation of numeric sine and/or cosine waveforms in different applications. In this work, authors compare two different DDS architectures: the traditional architecture, based on the exploitation of quarter wave symmetry, and the Symon's DDS (trigonometric DDS) presented in 2002. The two layout configurations have been implemented in 90 nm technology and compared in terms of area, speed and power consumption. Comparisons have been performed in terms of circuital complexity on architectures having the same Spurious Free Dynamic Range (SFDR) and phase resolution. Experiments show that the trigonometric architecture is very efficient in terms of area.

The operation of the smart grid is expected to be heavily reliant on microprocessor-based control. Thus, there is a strong need for interoperability standards to address the heterogeneous nature of the data in the smart grid. In this research, we analyzed in detail the security threats of the Generic Object Oriented Substation Events (GOOSE) and Sampled Measured Values (SMV) protocol mappings of the IEC 61850 data modeling standard, which is the most widely industry-accepted standard for power system automation and control. We found that there is a strong need for security solutions that are capable of defending the grid against cyber-attacks, minimizing the damage in case a cyber-incident occurs, and restoring services within minimal time. To address these risks, we focused on correlating cyber security algorithms with physical characteristics of the power system by developing intelligent agents that use this knowledge as an important second line of defense in detecting malicious activity. This will complement the cyber security methods, including encryption and authentication. Firstly, we developed a physical-model-checking algorithm, which uses artificial neural networks to identify switching-related attacks on power systems based on load flow characteristics. Secondly, the feasibility of using neural network forecasters to detect spoofed sampled values was investigated. We showed that although such forecasters have high spoofed-data-detection accuracy, they are prone to the accumulation of forecasting error. In this research, we proposed an algorithm to detect the accumulation of the forecasting error based on lightweight statistical indicators. The effectiveness of the proposed algorithms was experimentally verified on the Smart Grid testbed at FIU. The test results showed that the proposed techniques have a minimal detection latency, in the range of microseconds. Also, in this research we developed a network-in-the-loop co-simulation platform that seamlessly i

Data Distribution Service (DDS) is a decentralized, zero-configuration, communication middle-ware. This thesis presents a performance analysis of a communication based on DDS in the context of industrial robotics. The purpose is to find out if DDS is an adequate alternative for establishing a communication network between industrial robots, as well as other devices, and consider the advantages and disadvantages that this technology brings. Several current works are explored to give an insight in the current state of smart industrial automation, as well as to serve as a basis for the tests conducted in this thesis related to DDS performance. Using ABB industrial robots, a prototype is prepared and a series of experiments are carried out in order to measure the performance of the connection compared to a traditional end-to-end Transmission Control Protocol (TCP) socket. After explaining both the software and hardware architecture of the build setup, several test cases are presented in order to compare the performance of the system with different configuration parameters and network traffic conditions. An analytic review on the capabilities of the prototype, based on the test data is presented. The specific DDS distribution used in this thesis complies with the requirements needed by ABB robots in many different applications.

[Resumen] El uso de middleware de distribución facilita la programación de sistemas distribuidos heterogéneos, y por extensión también puede facilitar la generación automática de código como parte de una estrategia de desarrollo basada en modelos. Sin embargo, este middleware presenta una complejidad añadida que dificulta su uso en sistemas con ciertos requisitos de criticidad o de tiempo real. En este trabajo se hace una revisión de algunos estudios previos en los que se muestra la posibilidad de utilizar un middleware de distribución centrado en los datos (DDS, Data Distribution Service) para la integración de aplicaciones con criticidad mixta en sistemas distribuidos.

The convergence of Operational Technology and Information Technology is driving integration of the Internet of Things and Industrial Control Systems to form the Industrial Internet of Things. Due to the influence of Information Technology, security has become a high priority particularly when implementations expand into critical infrastructure. At present there appears to be minimal research addressing security considerations for industrial systems which implement application layer IoT messaging protocols such as Data Distribution Services (DDS). Simulated IoT devices in a virtual environment using the DDSI-RTPS protocol were used to demonstrate that enumeration of devices is possible by a non-authenticated client in both active and passive mode. Further, modified sequence numbers were found to be a potential denial of service attack, and malicious heartbeat messages were fashioned to be effective at denying receipt of legitimate messages.

Just as the Internet of Things is set to change how devices are being used and connected in society in general, the Industrial Internet of Things will change the industries. In an industrial production line there are often many heterogeneous devices, and the requirements on the real-time properties of the communication between them are often strict. Creating a communication solution for the different devices, that also meet such requirements, is difficult. The traditional way for industrial devices to communicate is directly with each other or via a central point, but this communication solution is inflexible and difficult to scale up. One possible way to make communication and information sharing between devices easier is to use a dedicated middleware to handle the communication. One middleware standard is the Data Distribution Service (DDS) defined by the Object Management Group. In this thesis a DDS middleware from a specific vendor (vendor name is removed due to company confidentiality) is implemented and evaluated. The middleware is evaluated based on (1) an implementation in a prototype which shows how the middleware performs in a real-life industrial context, and (2) a simulation that showcases the potential of the technology. The DDS middleware was shown to function with a specific set of existing industrial hardware and software. The real-time properties of the communication system were studied and found to be around 3.5 times slower, when using the prototype setup, than those of the replaced communication solution. However, the round trip latency was still only 2 ms on average and 4.1 ms maximum when using the preferred settings. The simulation showed that there is potential for the DDS technology to be used in more advanced scenarios and that it should be investigated further.

Many web applications are vulnerable to Injection and Cross-site scripting. These attacks are often focused on infrastructural parts of the application. This thesis investigates if Domain-Driven Design can unify existing technical protection mechanisms as well as provide protection for attacks aimed at the business logic of an application. The performance of data validation and transformation performed with components from Domain-Driven Design is evaluated. The evaluation is performed by exposing an E-commerce application to dangerous injection and cross-site scripting strings. The data validation was found to be accurate and flexible and context mapping aided the understanding of correct data treatment depending on where in the application it is located or travelling to.

This master thesis presents a new software architecture and the proof of concept of the software architecture called RPAS Mission Management Architecture (RIMA). RIMA aims to provide more intelligence to the RPAS, such increase the automation of the mission performed with Remotely Piloted Aircraft Systems (RPAS). The predecessor of RIMA is a software architectures called UAS Service Abstraction Layer (USAL) which has been evaluated against others software architectures, Robotics Operative System (ROS) and OpenJAUS, under the guidelines of ISO 9126. The evaluation performed among software architecture has used to identify the strengths and weaknesses of each one in order to improve the definition of RIMA. The middleware used in RIMA is by Real-Time Innovation (RTI) which implements the Data Distribution Service (DDS) standard. The master thesis follows describing the structure of RIMA and propose a practice case and an example of data model to use in RIMA. The conclusions explain the results of the master thesis and propose several future work in order to improve the different aspect of the architecture.

This paper is part of a study of intelligent architectures for distributed control and communications systems. The study focuses on optimizing control systems by evaluating the performance of middleware through quality of service (QoS) parameters and the optimization of control using Quality of Control (QoC) parameters. The main aim of this work is to study, design, develop, and evaluate a distributed control architecture based on the Data-Distribution Service for Real-Time Systems (DDS) communication standard as proposed by the Object Management Group (OMG). As a result of the study, an architecture called Frame-Sensor-Adapter to Control (FSACtrl) has been developed. FSACtrl provides a model to implement an intelligent distributed Event-Based Control (EBC) system with support to measure QoS and QoC parameters. The novelty consists of using, simultaneously, the measured QoS and QoC parameters to make decisions about the control action with a new method called Event Based Quality Integral Cycle. To validate the architecture, the first five Braitenberg vehicles have been implemented using the FSACtrl architecture. The experimental outcomes, demonstrate the convenience of using jointly QoS and QoC parameters in distributed control systems.

Actually, the creation of middleware platforms for real time distributed systems is a big challenge to research and technology. There are not enough programing techniques, making the development of these systems a complex and expensive task. Nowadays, the development of techniques of middleware and distributed programing has created important results and proposals, almost all of them oriented to remote calls and service invocation systems. The last middleware platforms involve advanced programing techniques related to Aspect-Oriented Programing. This research shows the development of a distributed systems middleware platform for the publishing/subscription model, we are pretending that our platform will be use for the research of advanced techniques for event based distributed systems. This paper shows the findings found into the standard development and adaptation toward the C# language programing, where feasibility of applied advanced programing techniques into the open source practical development of DDS (Data Distribution System) middleware is probed.

13 p., DDS is a recent specification aimed at providing high-performance publisher/subscriber middleware solutions. Despite being a very powerful flexible technology, it may prove complex to use, especially for the inexperienced. This work provides some guidelines for connecting software components that represent a new generation of automation devices (such as PLCs, IPCs and robots) using Data Distribution Service (DDS) as a virtual software bus. More specifically, it presents the design of a DDS-based component, the so-called Automation Component, and discusses how to map different traffic patterns using DDS entities exploiting the wealth of QoS management mechanisms provided by the DDS specification. A case study demonstrates the creation of factory automation applications out of software components that encapsulate independent stations.

How amazing would it be to prevent illegal copies of computer games? Game developers work with the hope that they can make good profit out of their games, but when they know that they would not sell much they will be so disappointed and that is because once a few original copies of their games are released, soon or late, there will be illegal copies available in the market. Working on how to distinguish between a legal copy and an illegal copy is the general topic of this thesis., In a game there are many images and textures used for graphical purposes. One of the most recent texture file extensions used in modern games to store Microsoft DirectDraw Surface which is the basic image unit in Microsoft DirectX graphics is DirectDraw Surface or DDS in short. In this thesis, it was attempted to embed as many bits (watermark/ message) as possible and retrieve the bits after embedding to mark the file in a distinguishable way. The result has been very promising under different circumstances., +46723136160

ObjectiveTo examine the association between maternal hospital diagnoses of obesity and risk of cerebral palsy (CP) in the child.Study designFor all California hospital births from 1991-2001, we linked infant and maternal hospitalization discharge abstracts to California Department of Developmental Services records of children receiving services for CP. We identified maternal hospital discharge diagnoses of obesity (International Classification of Diseases, 9th edition 646.1, 278.00, or 278.01) and morbid obesity (International Classification of Diseases, 9th edition 278.01), and performed logistic regression to explore the relationship between maternal obesity diagnoses and CP.ResultsAmong 6.2 million births, 67 200 (1.1%) mothers were diagnosed with obesity, and 7878 (0.1%) with morbid obesity; 8798 (0.14%) children had CP. A maternal diagnosis of obesity (relative risk [RR] 1.30, 95% CI 1.09-1.55) or morbid obesity (RR 2.70, 95% CI 1.89-3.86) was associated with increased risk of CP. In multivariable analysis adjusting for maternal race, age, education, prenatal care, insurance status, and infant sex, both obesity (OR 1.27, 95% CI 1.06-1.52) and morbid obesity (OR 2.56, 95% CI 1.79-3.66) remained independently associated with CP. On stratified analyses, the association of obesity (RR 1.72, 95% CI 1.25-2.35) or morbid obesity (RR 3.79, 95% CI 2.35-6.10) with CP was only significant among women who were hospitalized prior to the birth admission. Adjusting for potential comorbidities and complications of obesity did not eliminate this association.ConclusionsMaternal obesity may confer an increased risk of CP in some cases. Further studies are needed to confirm this finding.

On this work a low cost OFDM transmitter for underwater sensor networks is presented. The transmitter is based on a low power microcontroller that governs a DDS in order to generate the output data -OFDM symbols- avoiding the IFFT computations. This solution represents a new design perspective for the current UWSN -mainly based on FPGAs or DSPs, allowing to reduce the cost, the power consumption and the size of the current transmitters., Peer Reviewed, Postprint (author’s final draft)
