ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NVThe physics associated with transmitting and receiving a telemetry signal at a frequency greater than an octave above the current operating band is such that an end-to-end evaluation of the complete data link system (both the transmit and receive side) is required. In 2012, Airborne Instrumentation Systems Division (AISD), Naval Air Warfare Center Weapons Division (NAWCWD) was sponsored by the Office of the Secretary of Defense (OSD) to develop a couple of short-range air-to-air missile platforms that use a specially-designed warhead-replaceable telemetry section incorporating three data links: (1) an S-band link to transmit Time- Space-Position Information (TSPI), (2) an C-band link, and (3) an additional S-band link where the latter two are transmitting the same pseudo-random bit sequence at the same effective radiated power level. Flight testing will consist of a series of captive tests conducted over land and water. The tests will be performed under a variety of conditions to induce potential issues caused by multipath, atmospheric ducting, fast-slewing of the tracking antenna, and large propagation losses. Flight testing will culminate with the live-fire of a missile over a military land range. This paper describes the continuing efforts of this test program from these series of flight tests, thus quantifying the performance of C-band telemetry data transmission as compared to the S-band.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, NevadaDuring the era 2000-2002, the U.S. Air Force C-17 Follow-on Flight Test Program (FOFTP) transitioned to total bulk data collection employing the Veridian OMEGA™ Intelligent Multiplexer (IMUX) and associated Series 3000 Telemetry Processor. Advanced planning for the data management was deficient; engineers and analysts were overwhelmed by the actual quantity of instrumentation data collected, at a rate of 2- to 3-gigabytes per flight test hour. In fiscal year (FY) 2003, the Test Director initiated comprehensive planning for management of the C-17 data elements. Including the bulk instrumentation data collected, this plan also addressed the management of programmatic information and correlation from the test definition program phase through the archiving of test reporting Information. The envisioned end-state of the C-17 test data archive effort, also referred to as the C-17 Enterprise Test Data Management System (ETDMS), seeks to provide the C-17 Test Team with cradle-to-grave data management at a level unprecedented in the flight test community and is described herein. Once funding was received, the C-17 Integrated Product Team (IPT) has aggressively moved into deploying the C-17 ETDMS at the Air Force Flight Test Center (AFFTC) located at Edwards Air Force Base, California. Five modest objectives were set for the effort at initiation; these were: Objective 1: Establish C-17 Technical Library; Complete Deployment of LiveLink Distribution System Objective 2: Improve Data Analysis (Telemetry) Toolset and Products; Train Users Objective 3: Modernize Legacy Databases/Applications (Measurands, Calibrations, Generation of the Test Parameter Requirements [TPR] Document) Objective 4: Fix the Test Planning and Test Point Tracking User Interface Objective 5: Implement the Approved ETDMS Framework The C-17 ETDMS will link the many geographically separated users of C-17 test results in near real-time. Thus, providing the program decision-makers with the information required to support the current worldwide combat operations tempo by joint force elements as exhibited during the recent deployments and sustainment of operations in the Southwest Asian AOR. Collaterally, the C-17 ETDMS will support the efforts of our co-located NASA-Dryden colleagues seeking to improve the abilities of our National Airspace System (NAS) to support industry initiatives such as aircraft health monitoring and “call-ahead” maintenance planning. Currently ahead of schedule and within projected costs boundaries, the C-17 ETDMS will provide government off-the-shelf (GOTS)/commercial off-the-shelf (COTS) solutions to the C- 17 test community during FY 2005.

ITC/USA 2014 Conference Proceedings / The Fiftieth Annual International Telemetering Conference and Technical Exhibition / October 20-23, 2014 / Town and Country Resort & Convention Center, San Diego, CAAirbus is authorized to use S-band for Telemetry transmission until 2015. In October 2011, the decision was taken to move to C-band in 2013, to cope with Airbus development aircraft planning. The objective was a real challenge for 2 main reasons: C-band channel was not characterized in Airbus transmission environment and it was necessary to validate the propagation performance for Flight Tests uses. The selected solution is based on Coded Orthogonal Frequency Division Multiplexing (COFDM) modulation. There was no existing solution so it has led the Airbus Test Centre to drive the development of its own C Band solution. C-band telemetry at Airbus has been tested and evaluated in flight from April 2012. The first goal was to check the coverage and the impact of the bad weather condition. Besides, it was necessary to characterize the channel to choose the optimised parameters for the waveform in the Toulouse Blagnac environment. This selection of parameters allows the high quality and increased data rate required for Airbus Telemetry to be reached. The test results consolidated the choice of a COFDM modulation, when given the high sensitivity to multipath of usual Frequency Modulation in the airport environment full of buildings and aircrafts. Moreover, it has been possible to reach a similar quality to the S-band telemetry systems, thanks to a fine tuning of the waveform parameters, and tracking system. Deployment of the system by modifying 8 reception antennas and 12 development aircrafts was done over a span of 4 weeks in January 2014. No impact on Airbus A350 certification campaign occurred due to close collaboration with Flight Test Operations. The new Telemetry system enables an increase of telemetry capabilities in the future, especially the data throughput, simplified remote control and monitoring. This experience is an opportunity to set up a new standard.

Full textAbstract:
This thesis describes the design and evaluation of two devices to be included in the next generation of the family of devices called the Boundary Layer Data System (BLDS). The first device, called the Quasi-Static Strain Data Acquisition System, is a continuation of the BLDS-M series of devices to be known as the Flight Test Data System (FTDS) that uses a modular approach to acquire non-flow, quasi-static mechanical strain measurements. Various breakout boards and development boards were used to synthesize the device, which were housed by a custom PCB board. The system is controlled by the SimbleeTM System on a Chip (SOC), and strain measurements are acquired using the HX711 analog-to-digital converter (ADC), and acceleration measurements are acquired with the ADXL345 accelerometer. The Arduino IDE was used to program and troubleshoot the device. The second device, called the Dynamic Strain Data Acquisition System, is a laboratory proof-of-concept device that evaluates various methods of acquiring dynamic strain measurements that may be used in future FTDS designs. A custom PCB board was designed that houses the microcontroller and the various passive components and ICs used to acquire and store strain measurements. The system is controlled by the Atxmega128A4U microcontroller, and measurements are acquired using the AD7708 external ADC and the on-board ADC of the microcontroller. Atmel StudioTM was used to program the microcontroller in C/C++ and to troubleshoot the device. Both devices were tested extensively under room temperature and low temperature conditions to prove the reliability and survivability of each device. The quasi-static data acquisition system was validated to acquire and store measurements to a microSD card at 10 Hz, with a peak operating current under 60 mA. The dynamic data acquisition system was proven to acquire a thousand measurements at 1 kHz and store the data to a microSD card, with a peak operating current under 60 mA.

In addition, the flight test plans to make this comparison have been discussed. Captive Carry Test Flights (on a F-18 fighter jet) over the NAVAIR Sea and Land Ranges at Point Mugu and China Lake were conducted during the April-July 2014 timeframe. In addition a Live Fire Test Flight over the Land Range of the specially outfitted missile was performed in July 2014 as well. This paper will discuss these series of flights tests and provide a performance assessment of the data quality between the C-Band and S-Band telemetry data links. In addition, lessons learned from the various test flights will be included as well. Due to publication deadlines, the results will be summarized at the actual conference.

Even the characteristics of the new frequencies just as the new frequency environment are a challenge for the operations in this bands when changing from a well-known frequency environment to a unknown new one. This paper describes the way used at Airbus Defense and Space Flight Test Ground Station to get experience with new equipment and to learn more about the new environment. Repeatable and comparable tests allowed training for the operators and the optimization of the equipment and procedures with the new environment. Although many of the problems or features observed during the tests where expected in advance, but even unexpected results could be identified.

This thesis is a part of the Local Hawk student project where the overall goal is to develop a Autonomous Unmanned Aerial Vehicle (AUAV). The project was initiated by Kongsberg Defence Systems (KDS) and is developed in collaboration with the Norwegian University of Science and Technology (NTNU). In an AUAV it is necessary to have a guidance system in order to be autonomous. To be able to test guidance principles in practice without risking the Local Hawk airframe the need of a ground based test platform became apparent. This thesis is the development of the Local Bug Test Platform.The Local Bug is based on a R/C car and utilizes electronics used and developed in the Local Hawk project. In order to understand the system behaviour, vehicle modelling is discussed and two models are presented. One of them is used in a SIMULINK simulator design for the Local Bug. The simulator is used to ensure the correct controller behaviour before it is tested on the real system. Phoenix II is the backbone of the Local Bug electronics and is used to gather measurement data, log data to memory and execute controller algorithms. Custom made C-code is used as a framework providing all the functionality needed. A introduction to Real-Time Workshop is given, and a step-by-step guide on how to use RTW generated C-code on the Phoenix II for controller purposes.A heading controller is designed and used in combination to two different guidance algorithms. The Line of Sight algorithm aims for the next waypoint regardless where the vehicle is positioned relative other waypoints. A Cross-Track Error algorithm with look ahead distance functionality focuses on minimizing the vehicles distance from a desired path. Both algorithms successfully guides the vehicle trough the test route visiting all the waypoints. The Local Bug is now usable as a test platform for controller algorithms. Measurements are logged to memory making it possible to analyse the performance after a test has been conducted. The overall functionality is found to be satisfactory and the Local Hawk project now has its desired controller/guidance test platform.

Full textAbstract:
Test coverage criteria introduces metrics to measure the adequacy of a test suite as well as defined rules for performing software testing. This makes it possibly to formally define requirements for testing in various industries where software quality is essential, such as in aviation. This bachelor thesis aims to study the effectiveness of 11 different coverage criteria in two ways. Firstly how effective they are at finding faults and secondly their cost effectiveness. Test cases were created for each individual criteria for three different programs. The effectiveness of these test cases was then measured using mutation analysis. The results revealed that the scale of the experiment was too small to truly draw any conclusions regarding effectiveness. It was however shown that due to the “test noise” effect, the effectiveness of the test criteria can differ notably. It was also shown that test coverage criteria alone may not be sufficient in order to perform efficient testing.

Les composites Carbone/Carbone (C/C), largement utilisés à hautes températures dans des environnements oxydants, sont sensibles à l'oxydation dès 400°C. Deux voies sont envisagées pour accroître la tenue à l'oxydation de ces matériaux. La première est de renforcer la force de la liaison fibre/matrice en modifiant les propriétés de surface des fibres de carbone. La seconde voie d 'étude consiste à remplacer une partie de la matrice carbone par un oxyde. L'introduction d'une nouvelle phase conduit à la création de nouvelles interfaces dans les matériaux. L'ensemble des résultats obtenus à partir des caractérisations physico-chimiques et macroscopiques des matériaux élaborés permettent alors de répondre à la problématique qui est de connaître le rôle des interfaces dans les propriétés macroscopiques de composites C/CC/C composites are widely used as structural parts in oxiding environment. Yet, they become very sensitive to air oxidation for temperature higher than 400°C. This work proposed two methods to improve their oxidation resistance :(i) the fiber/matrix bond is increased by modifying the properties of the carbon fiber surface, and (ii) a fraction of the carbon matrix is substitued by an oxide phase.Introduction of new constituants leads to the creation of new material interfaces. Thus, the influence of the interfaces on the macroscopic properties of the composite is evaluated by physico-chemical and macroscopic characterizations

The procedure of testing the implemented software is important and should be an essential and integrated part of the development process. In order for the testing to be meaningful it is important that the testing procedure ensures that the developed software meet certain requirements. The testing procure is often controlled by some sort of test specification. For many companies it is desirable to automate this procure. The focus of this thesis has been to automate a small subpart of the manual tests today performed related to SAAB:s air traffic management system. The automation has been achieved by studying the existing test specification which involves a lot of manual operations and to write software that mimics a few of these test cases. The thesis has resulted in a test framework which automates a small subset of the manual tests performed today. The framework has been designed to be scalable and to easily allow more test cases to be added by the personnel when time permits. The test framework has also been integrated with SAAB:s existing CI/CD workflow.

Previous issue date: 2015Introduction: Children’s own perceptions and accounts of their asthma diagnosis have proved to be reliable and relevant to disease control.Objective: The aim is to validate the Brazilian Portuguese version of the Childhood Asthma Control Test (c-ACT) in children aged between 4 and 11 years.Methods: The investigation was divided into two stages: The first stage comprised the translation and linguistic adaptation of the instrument, while the second consisted of testing the psychometric properties of validity and reliability.Results: A total of 105 participants were included, aged between 4 and 11 years. Validity: all correlations between the total score and items on the questionnaire were significant and obtained values of r = > 0. 3. There was no correlation between the total score of the questionnaire and lung function. The controlled asthma group showed significantly higher c-ACT scores than those of the uncontrolled asthma group (controlled 22±2. 9 VS uncontrolled 16. 3±5. 3 p <0. 001). Reliability: The Alfa de Cronbach coefficient for the total c-ACT score was 0. 677 (CI95% 0. 573-0763). In the assessment of sensitivity to change, the effect size was 0. 8 and the intraclass correlation coefficient was 0. 598. No floor or ceiling effects were observed in the sample studied.Completed: The Brazilian version of the Childhood Asthma Control Test proved to be valid and reliable.

Full textAbstract:
Chez les vertébrés, la douleur est perçue par des neurones spécialisés, les nocicepteurs, dont le corps cellulaire est localisé dans les ganglions de la racine dorsale (DRG) et qui présentent une grande hétérogénéité. Nous cherchons donc à identifier de nouveaux marqueurs des sous populations de nocicepteurs afin de pouvoir comprendre cette diversité et d’attribuer des fonctions physiologiques précises à ces différentes sous-populations neuronales. Nous avons identifié le gène GINIP, spécifiquement exprimé dans une sous populations de nocicepteurs non peptidergiques et définissant deux classes particulières de neurones : les neurones MRGPRD+ et les C-Low Threshold MecanoReceptors (C-LTMRs). Durant ma thèse, j’ai cherché à savoir quelles modalités sensorielles sont détectées et transmises par la population GINIP+. Pour cela, j’ai tiré avantage d’un modèle murin ginip généré au laboratoire, permettant d’éliminer spécifiquement les neurones GINIP+ au sein des neurones du DRG. J’ai pu démontrer que l’ablation ciblée de ces neurones entraine une diminution de la douleur induite par l’injection de formaline, cela sans affecter la sensibilité thermique ou mécanique. Sachant que les neurones MRGPRD positifs ne sont pas impliqués dans la réponse douloureuse induite par l’injection de formaline, mais jouent un rôle primordial dans la mécano sensibilité en condition normale et pathologique, notre étude montre que la réponse douloureuse induite par l’injection de formaline est due à l’activation des C-LTMRs. En conclusion, notre étude révèle que les C-LTMRs agissent en tant que puissants modulateurs des douleurs chimiques et mécaniquesPrimary sensory neurons are heterogeneous by myriad of molecular criteria. However, the functional significance of this remarkable heterogeneity is just emerging. Here we used our recently generated ginip mouse model to selectively ablate the cutaneous free nerve endings MRGPRD+ neurons and the C-Low threshold mechanoreceptors (C-LTMRs). Ablation of GINIP-expressing neurons led to a significant decrease of formalin-evoked first pain and a complete absence of the second phase pain response, without affecting thermal or mechanical sensitivity. Knowing that MRGPRD+ neurons are dispensable for formalin-evoked pain and that these neurons play a critical role in acute and injury-induced mechanical pain, our data demonstrate that formalin-induced pain hypersensitivity is primarily transduced via C-LTMRs, and suggest that C-LTMRs and MRGPRD+ neurons play antagonistic roles in transduction of acute and injury-induced mechanical pain. Therefore, our results suggest that C-LTMRs act as strong modulators of chemical and mechanical pain signals

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, NevadaThe ability to dynamically configure our ground stations to support a wide array of fighter/attack aircraft programs has lead McDonnell Douglas Aerospace (MDA) to seek alternatives to commercially available ground stations. Cost effectiveness and fast response time to these widely varying needs is paramount to staying competitive in today's current defense environment. VME (Versa Modular European) architecture has provided a platform that fulfills these requirements while requiring a minimum of in house designs which can be expensive and time consuming to implement. MDA is now in its third generation of VME based ground systems. These systems are highly extensible due to their reliance on software and programmable hardware systems and are inexpensive due to their use of commercial grade VME cards. This paper describes the current generation TM/Quicklook Ground Station and the Data Editor (Preprocessor) Station and it also provides a perspective of how the designers solved some common problems associated with VME architecture. These stations are now in use at MDA test sights in St. Louis, Patuxent River NAWC, Edwards AFB, and Eglin AFB.

We discuss the design and analysis of a code generator for C++, implemented in the Umple model-oriented programming technology. Umple adds UML constructs and patterns to various base programming languages such as Java and PhP. Umple code generators create code for those constructs, which can include UML associations and state machines, as well as patterns such as immutable and singleton. Base language methods are passed through unchanged along with the generated code. Creating a C++ code generator for Umple posed many challenges, all of which are discussed in this thesis: We had to focus on the appropriate C++ idioms and stylistic conventions to follow. We followed a test-driven development process to ensure that the resulting code was correct. To evaluate the work, we compared our C++ generator with those in other tools such as ArgoUML and IBM Rational Software Architect. We conclude that our C++ generator is superior in many ways to these widely used tools because it is more complete and generates better quality code.

Introduction: Children?s own perceptions and accounts of their asthma diagnosis have proved to be reliable and relevant to disease control. Objective: The aim is to validate the Brazilian Portuguese version of the Childhood Asthma Control Test (c-ACT) in children aged between 4 and 11 years. Methods: The investigation was divided into two stages: The first stage comprised the translation and linguistic adaptation of the instrument, while the second consisted of testing the psychometric properties of validity and reliability. Results: A total of 105 participants were included, aged between 4 and 11 years. Validity: all correlations between the total score and items on the questionnaire were significant and obtained values of r = > 0.3. There was no correlation between the total score of the questionnaire and lung function. The controlled asthma group showed significantly higher c-ACT scores than those of the uncontrolled asthma group (controlled 22?2.9 VS uncontrolled 16.3?5.3 p <0.001). Reliability: The Alfa de Cronbach coefficient for the total c-ACT score was 0.677 (CI95% 0.573-0763). In the assessment of sensitivity to change, the effect size was 0.8 and the intraclass correlation coefficient was 0.598. No floor or ceiling effects were observed in the sample studied. Completed: The Brazilian version of the Childhood Asthma Control Test proved to be valid and reliable.

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NVTelemetry data from flight tests are normally plotted using MatLab™ or other third party software. For most of the trajectory and flight parameters, a static 2D or 3D line graph does not provide the proper data visualization that can be accomplished with 3D software. Commercial 3D software can be expensive and difficult to customize, and writing custom software using Direct3D or OpenGL can be complex and time consuming. These problems were overcome using C# and Windows Presentation Foundation (WPF) to quickly and easily create a 3D Telemetry Theater and Trajectory Visualization Tool to dynamically display actual and simulated flight tests.

Full textAbstract:
In the aviation industry, the use of software development tools is not as easily adopted as in other industries. Due to the catastrophic consequences of software errors in airborne systems, software development processes has rigorous requirements. One of these requirements is that a code standard must be followed. Code standards are used to exclude code constructions which could result in unwanted behaviours. The process of manually ensuring a specific code standard can be costly. This process could be automated by a tool for static code analysis, however, this requires a formal qualification. This thesis evaluates the process of qualifying a tool for static code analysis in accordance with the requirements of the major aviation authorities EASA and FAA. To describe the qualification process, a literature study was conducted. To further explain how an existing tool could be put through the qualification process, a case study of the existing tool Parasoft C/C++ test was conducted. The results of the literature study show what processes must be completed in order to qualify a static code analysis tool. Importantly, the study shows that no requirements are put on the development process of the tool. This was an important takeaway as it meant that an existing tool could be qualified without any additional data from the developer of the tool. The case study of Parasoft C/C++ test showed how the tool could be configured and verified to analyze code in accordance with a small set of code rules. Furthermore, three documents including qualification data were produced showing how the qualification process should be documented in order to communicate the process to an authority. The results of the thesis do not provide the full picture of how a tool could be qualified as the software, in which the tool is used, is considerations the are specific to the software the tool is used to develop still need to be taken into consideration. The thesis does, however, provide guidance on the majority of the applicable requirements. Future research could be done to provide the complete picture of the qualification process, as well as how the process would look like for other types of tools.Inom flygindustrin är användandet av olika programmeringsverktyg inte lika självklart som inom andra industrier. På grund av de katastrofala konsekvenser som fel i mjukvaran i ett flygplan kan resultera i finns det rigorösa krav på mjukvaruutvecklingsprocessen. Ett av dessa krav är att en viss kodstandard måste upprätthållas. Kodstandarder används för att exkludera vissa strukturer i kod som kan leda till oönskat beteende. Upprätthållandet av en viss kodstandard är en långdragen process att genomföra manuellt, och kan därför automatiseras med hjälp av ett statiskt kodanalysverktyg. För att kunna använda ett sådant verktyg behövs däremot en formell verktygskvalificering. I denna uppsats kommer kvalificeringsprocessen av ett verktyg för statisk kodanalys att evalueras enligt de krav som de två stora flygmyndigheterna EASA och FAA ställer. För att förklara processen av att kvalificera ett sådant verktyg gjordes en litteraturstudie följt av en fallstudie av det existerande verktyget Parasoft C/C++ test. Resultaten av litteraturstudien beskriver de olika processerna som måste genomföras för att kvalificera ett statiskt kodanalysverktyg. Noterbart är att resultaten visar att inga krav ställs på utvecklingsprocessen av verktyget själv. Detta betyder att ett existerande kommersiellt verktyg kan kvalificeras utan att verktygsutvecklarna själva behöver bidra med extra information. Fallstudien visade hur verktyget Parasoft C/C++ test kan konfigureras och verifieras att följa en viss kodstandard. Vidare resulterade fallstudien i utkast av de nödvändiga dokumenten som behöver produceras för att kommunicera kvalificeringsprocessen till en myndighet. De resultat som presenteras i denna uppsats är i sig inte tillräckliga för beskriva hela kvalificeringsprocessen. Ytterligare överväganden som är specifika till den mjukvaran som verktyget ska användas till att utveckla måste göras för att en komplett kvalificering ska kunna genomföras. Uppsatsen bidrar däremot med riktlinjer och vägledning av majoriteten av de processerna som behöver genomföras. Ytterligare forskning kan göras för att bidra med den kompletta bilden av verktygskvalificering av ett statiskt kodanalysverktyg, samt hur kvalificering kan göras av andra typer av verktyg.

Full textAbstract:
Les infections chroniques par le virus de l’hépatite B (VHB) et le virus de l’hépatite C (VHC) sont des problèmes majeurs de santé publique à l'échelle mondiale. Il est primordial d’améliorer l’évaluation de la gravité de ces hépatites chroniques pour mieux rationaliser la prise en charge des patients. La ponction biopsie hépatique (PBH) était jusqu’à présent le « gold standard » pour le diagnostic et le pronostic de la fibrose hépatique. Cependant ses nombreuses limitations, effets secondaires sévères, et une fréquence élevée de faux négatifs et de faux positifs, on conduit ces dernières années à l’élaboration de biomarqueurs, utilisés seuls ou en combinaison. Aucune estimation des valeurs pronostiques de ces marqueurs non-invasifs n’a été réalisée. Le but de notre thèse a été de démontrer la valeur pronostique du FibroTest-ActiTest (FT-AT) chez les patients infectés par le VHC et le VHB. Nous avons pu participer à deux travaux sur 2 populations distinctes: Une cohorte prospective de 537 patients ayant une infection chronique par le VHC, chez qui le stade de fibrose et le grade d’activité ont été évalués le même jour par une ponction biopsie hépatique et par FT-AT. Une cohorte prospective de 1300 patients ayant une infection chronique par le VHB, chez qui le stade de fibrose, le grade d’activité par FT-AT et la charge virale VHB ont été évalués le même jour. Le but de ces deux travaux principaux de ces quatre années de Thèse était d’estimer et de comparer les valeurs pronostiques des nouveaux biomarqueurs (FT-AT, Score APRI, Score de Forns) et du score pronostique « standard » classique (Score de Child-Pugh) pour prédire la survenue des complications et la survie chez les patients ayant une infection chronique par le VHB ou le VHC. Les analyses de survie, méthodes univariée et multivariée, ont estimé la valeur pronostique des stades de fibrose (estimés par biopsie hépatique et par biomarqueurs) et des autres facteurs potentiellement prédictifs de la survenue des complications de la cirrhose et de la survie. La durée de survie a été calculée à partir de la date du FT-AT à la date de la survenue du premier évènement (complications de la maladie, décès toutes causes et décès lié au foie); puis comparée à la survie attendue dans la population française (avec appariement sur l’âge, le sexe, l’année d’inclusion et la durée de suivi). Les valeurs pronostiques de la biopsie hépatique et des biomarqueurs ont été estimées et comparées par les aires sous les courbes pronostiques ROC (AUROC). RESULTATS Travail sur la cohorte de 537 patients atteints de l’hépatite chronique CRésultats à 5 ans de suivi (publication en 2005). Les patients avec fibrose sévère avaient une survie sans complications ou décès liés au VHC à 78. 5% (IC 95% = [71. 2%-85. 9%]; 28 complications ou décès liés au VHC) et une survie sans décès lié au VHC de 92. 7% (88. 0%-97. 3%; 9 décès liés au VHC). Les patients avec fibrose modérée avaient une survie sans complications ou décès liés au VHC à 98. 8% (96. 6%-100%; 1 complication, P<0. 001) et une survie sans décès lié au VHC à 100% (aucun décès lié au VHC; P<0. 001). Les patients avec fibrose minime avaient une survie sans complications ou décès liés au VHC à 100% (aucune complication liée au VHC; P<0. 001) et une survie sans décès lié au VHC à 100% (aucun décès lié au VHC; P<0. 001). Le FT avait une meilleure valeur pronostique par rapport à la biopsie, pour la survenue des complications avec une AUROC [IC 95%] =0. 96 [0. 93-0. 97] vs 0. 91 [0. 85-0. 94; P=0. 01] et pour la survenue de décès lié au VHC: AUROC = 0. 96 [0. 93-0. 98] vs 0. 87 [0. 70-0. 94; P=0. 046]. La valeur pronostique du FT était significativement plus élevée par rapport à celle des autres scores (APRI, Forns, Pugh) en analyse univariée (P<0. 001) et en régression logistique (P<0. 01) prenant en compte la réponse au traitement et les autres facteurs pronostiques connus (co-infection VIH, consommation d’alcool). Résultats à 8 ans de suivi (rédaction d’article en cours en 2008). Les patients avec fibrose sévère avaient une survie sans complications ou décès liés au VHC à 71. 0% (IC 95% = [63. 0%-79. 1%]; 39 complications ou décès liés au VHC) et une survie sans décès lié au VHC de 76. 5% (66. 8%-86. 2%; 24 décès liés au VHC). Les patients avec fibrose modérée avaient une survie sans complications ou décès liés au VHC à 97. 0% (93. 5%-100%; 3 complications ou décès liés au VHC, P<0. 0001) et une survie sans décès lié au VHC à 89. 3% (73. 6%-100%; 3 décès liés au VHC; P<0. 0001). Les patients avec fibrose minime avaient une survie sans complications ou décès liés au VHC à 99. 5% (98. 6%-100%; 1 complication; P<0. 0001) et une survie sans décès lié au VHC à 99. 5% (98. 6%-100%; 1 décès lié au VHC; P<0. 0001). FT avait une meilleure valeur pronostique par rapport à la biopsie, pour la survenue des complications ou décès liés au VHC avec une AUROC [IC 95%] = 0. 91 [0. 86-0. 94] vs 0. 77 [0. 66-0. 85; P=0. 0006] et pour la survenue de décès lié au VHC: AUROC = 0. 88 [0. 79-0. 92] vs 0. 66 [0. 49-0. 78; P=0. 0002]; et pour la survie globale: AUROC = 0. 75 [0. 64-0. 82] vs 0. 56 [0. 44-0. 66; P=0. 0002]. La valeur pronostique du FT restait significative en régression logistique (P<0. 001) prenant en compte la réponse au traitement et les autres facteurs pronostiques connus. Travail sur la cohorte de 1300 patients atteints de l’hépatite chronique B (Article en cours de soumission, version révisée en cours). Parmi les 1074 patients inclus, il a été observé 50 complications avec ou sans décès liés au foie [survie sans complications ou décès liés au foie = 93. 4% (IC 95% = 91. 4%-95. 4%)], 36 décès [survie sans décès= 95. 0% (93. 2%-96. 8%)] avec 27 décès liés au foie [survie sans décès liés au foie = 96. 1% (94. 4%-97. 8%)]. FT avait une meilleure valeur pronostique par rapport à la charge virale ou aux ALT pour la survenue des complications ou décès liés au foie [AUROC=0. 89 (IC 95% 0. 84-0. 93) vs 0. 64 (0. 55-0. 71) vs 0. 53 (0. 46-0. 60); (P<0. 0001)], et une meilleure valeur pronostique dans l’analyse multivariée [coefficient de régression 5. 2 (3. 5-6. 9; P<0. 0001) vs 0. 53 (0. 2-0. 9; P=0. 007) vs -0. 001 (-0. 003-0. 000; P=0. 052)]. Une nouvelle définition du statut de porteur inactif du VHB est proposée avec un algorithme associant la charge virale et le score de FibroTest-ActiTest. Ce nouvel algorithme présente une valeur prédictive négative à 100% pour les décès liés au foie et/ ou complications. Parmi les 275 patients classés porteurs inactifs d’après la définition classique, 62 patients (22. 5%) avaient une fibrose présumée par FT, et 3 sont décédés ou ont eu des complications dans les 4 ans du suivi. Chez les patients ayant une infection chronique par le VHC, le FibroTest est un marqueur biochimique de la sévérité de la maladie avec une valeur pronostique à cinq ans et à huit ans meilleure que celle de l’histologie pour la prédiction des complications et des décès liés au VHC. Chez les patients ayant une infection chronique par le VHB, le FibroTest a une valeur pronostique à quatre ans similaire à celle de la biopsie hépatique. La combinaison de FibroTest-ActiTest et la charge virale permet de définir avec plus de précision le pronostic et le statut de « porteur inactif » que la définition classique.

Full textAbstract:
Background: Laboratory biomarkers are important adjuncts to clinical data in diagnosing neonatal sepsis. Available diagnostic tests often provide results 6 to 48 hours later. A bedside C-reactive protein (CRP) test may be able to exclude or diagnose sepsis within minutes. Objectives: The objectives were to validate the Alere AfinionTM point of care test (POCT) CRP in a tertiary neonatal unit against the gold standard CRP assay in use by the National Health Laboratory service and to determine the difference in time to obtaining a result between the two systems. Methods: A prospective observational study was conducted between February 2015 and June 2015. Neonates who were clinically indicated to undergo CRP testing were simultaneously tested using the POCT and laboratory assays. The sensitivities, specificities and predictive values for the POCT, with the laboratory test as the reference test were determined. The time to results between the two tests was compared. Results: There were 139 measured CRP sample pairs from patients with suspected or proven neonatal sepsis. Using 10 mg/L as the cutoff value for both CRP tests, the sensitivity, specificity, positive predictive value and negative predictive value were 97.4%, 99%, 97.4% and 99% respectively. The area under the receiver operating characteristic curve was 0.99 (p<0.001). The time to point of care result was 4 minutes. Laboratory results were registered at a mean of 4.7 hours but only checked after a mean of 6.8 hours. Conclusions: The POCT CRP and laboratory CRP test have excellent correlation in neonates and may be a useful, quick, reliable method to rationalise antibiotic usage, reduce costs and allow for earlier patient discharge.

Full textAbstract:
The GE Healthcare Life sciences organization develop and manufacture bioreactors, mixers, filtration skids and chromatography systems used together in a biomanufacturing platform. The platform is monitored and controlled by a distributed control system through a Programmable Logic Controller (PLC). The automation software controlling the platform is today tested and verified together with the physical units. The software use PROFIBUS, an industry standard for industrial automation, for communication and control of the units. Limited access to the physical units is usually a bottleneck and it's difficult to test abnormal situations to make sure the correct alarms are triggered. To reduce the hardware dependency and to provide support during test and verification, a virtual environment is developed to simulate the behavior of a bioreactor during execution. A .NET application has been developed together with a mathematical framework to simulate a cell culture and to return relevant process parameters such as pH, dissolved oxygen, temperature and weight. The results show that it's possible to simulate a bioreactor and to communicate with the control system. The software can be a valuable tool when developing and testing automation software but should not be used for process optimization or tuning of control parameters.

Full textAbstract:
Le test structurel est généralement limité aux test unitaires et basé sur une définition claire de la couverture du code. En particulier, le critère tous-les-chemins, qui requiert au moins un cas de test par chemin faisable, est reconnu comme offrant un haut niveau de confiance dans les test effectués. Ce document traite des difficultés de l'utilisation de ce type de test sur des fonctions composées d'appels à d'autres fonctions. Pour limiter l'explosion combinatoire du nombre de chemins résultant d'un traitement "inlining", nous choisissons d'abstraire les fonctions appelées par leurs spécifications. Nous incluons les informations fonctionnelles des fonctions appelées aux informations structurelles de la fonction appelante données sous forme de graphe de flot de contrôle. Cette représentation fonctionnelle et structurelle peut être vue comme une extension du CFG classique ce qui nous permet de définir de nouveaux critères de couverture assurant le maintien de la couverture complète de la fonction appelante tout en limitant au maximum le nombre de cas de test nécessaires.

Full textAbstract:
In 2005 Swedish Armed Forces (SAF) started a breeding program of military working dogs. The dogs leave SAF’s kennel at an age of 8 weeks and live with puppy raisers. To evaluate the suitability of dogs for military work the dogs conduct a behavioural test at an age of 15-18 months. An “Index value” is extracted from this behavioural test. The puppy raisers answered a modified version of Canine Behavioral Assessment and Research Questionnaire (C-BARQ) when the dogs were approximately 12 months old. Answered questionnaires and results from the behavioural test were obtained for 59 dogs. Dogs that had passed the behavioural test had tendency for higher scores for “Trainability” (p = 0.078) and “If lived with other animals” (p = 0.066). Failing dogs had significantly higher score for “Stranger Directed Fear” (p = 0.006), ”Non-Social Fear” (p = 0.005), “Dog Directed Fear” (p = 0.021), “Hours of daily activation” (p = 0.001), “Mounting objects” (p = 0.012), and a tendency for higher risk of “Urinating when home alone” (p = 0.058). In a regressions between the “Index value” and the values of the questions from C-BARQ, the “Index value” was negatively correlated to “Stranger Directed Fear” (p = 0.002), “Non-social Fear” (p = 0.003), and “Dog Directed Fear” (p = 0.006). The “Index value” was positively correlated to “Trainability” (p = 0.013), “Hours left home alone” (p=0.043), “Hyperactive” (p = 0.018), “Chases shadows/light spots” (p = 0.043), and a positive tendency for “Chewing on inappropriate objects” (p = 0.075). From a PCA at the categories in C-BARQ, 3 components were extracted. All three components had a correlation to the “Index value”. The results show that the use of C-BARQ can indicate whether the dog will pass the behavioural test or not.

Le vanadium étant l’un des meilleurs métaux catalytiques pour de tels réactions, nous avions à nous attaquer son problème de relargage dans le milieu réactionnel en vue d’applications acceptables pour l’environnement. Nous proposons donc dans cette thèse des catalyseurs au vanadium fixé à l’intérieur des nano pores de silices mésoporeuses hexagonales de type MCM-41. La grande dispersion et la rétention du vanadium sont promues grâce à la présence d’ion d’ancrage : Al(III), Ti(IV), Zr(IV) and Ce(IV). Une grande variété de catalyseurs de type V-(Al/Ti/Zr/Ce)-MCM-41 ont été préparés à partir de trois méthodes de synthèse: l’une, ultra-rapide en une étape assistée par micro-onde, la seconde à étapes séquentielles multiples mettant en œuvre une technique de pochoir moléculaire et la troisième à nombre d’étapes réduites utilisant un traitement thermique partiel d’une surface préalablement organosilylée avant le greffage des métaux. Un large panel de techniques physicochimiques fut appliqué à la caractérisation de ces solides avec une attention particulière portée à l’analyse de la bande de transfert de charge ligand-métal du vanadium au degré d’oxydation +5 dont le décalage vers le bleu est corrélé à la taille des clusters d’oxyde de ces ions. La rétention du vanadium dans le méthanol a été corrélée à la dispersion du vanadium comme la dégradation à l’air du 1,2-diphényle-2-méthoxyéthanol. Ce substrat fut choisi comme modèle pour étudier la dégradation de la lignine par clivage C-C ou C-O. Notons que ce bio-polymère produit du phénoxypropanol methylé bio-sourcé utilisé dans les bio-carburants et comme précurseur en chimie fine. Dans le cas présent, un balayage à haut débit de la dégradation de cette molécule mettant en œuvre 96 mini-réacteurs en parallèle a permis de sélectionner le solvant, le métal d’ancrage et la teneure des deux métaux donnant la plus haute conversion. Contrairement aux catalyseurs homogènes, nos catalyseurs présentent une très haute sélectivité en clivage C-CThe search for practical large-scale, fast, clean and energy saving chemical processes are highly regarded in the frame of a sustainable development, particularly for the most problematic oxidation reactions. Apart from chemical engineering solutions, improving the process using heterogeneous catalysis is one of the most adapted solution. Vanadium being considered the best metal for such kind of reactions, one had to tackle the problem of its high dispersion on a support to minimize its high propensity for leaching and to optimize its stability for practicable, safe and clean uses. In the present thesis, vanadium is supported inside the nanopores of a mesoporous silica of MCM-41 type where the high dispersion is assisted by the presence of anchoring ions such as Al(III), Ti(IV), Zr(IV) and Ce(IV) ions. A large set of V-(Al/Ti/Zr/Ce)-MCM-41 catalysts was prepared according to three different methods of preparation: i) ultra-fast one-pot synthesis protocol using the assistance of microwave, ii) post-synthesis modification using molecular stencil patterning (MSP) technique and iii) partial thermal treatment (PTT) of the organo-silylated support. The catalysts were characterized thoroughly using a panel of physical techniques and, particularly, the blue shift of the optical gap measured from the vanadium charge transfer band known to correlated with the dispersion of the metal. In complement, the stability was tested from metal leaching using methanol as a corrosive solvent while their catalytic reactivity was estimated in the aerobic oxidation of 1,2-diphenyl-2-methoxyethanol. This is a model reaction that simulates the oxidative C-C bond cleavage in lignin, the most difficult and crucial step in the degradation of this biopolymer, then producing in a clean way valuable methoxylated phenoxy propanol units useful for biomass fuels or bio-sourced precursors for fine chemistry. A high throughput screening approach was applied to test this aerobic oxidation reaction running over 96 reactors in parallel at the same temperature and sorting out the best catalysts with the most suitable anchoring ions and metal loading for the highest catalytic efficiency
在可持续发展的背景下，对于清洁高效节能可行的大规模化工过程尤其是存在诸多问题的氧化反应过程的探索倍受瞩目。除化学工程解决方案之外，通过多相催化来改进反应过程也是最可行的途径之一。钒被认为是最适合于催化此类反应的金属之一，其亟待解决的问题是实现钒在载体上的高度分散，并最大限度地降低其浸出倾向，改善其稳定性，从而实现对其安全清洁有效的利用。本文提出将钒负载于MCM-41型六方介孔二氧化硅的纳米孔道中，通过锚定离子如Al(III)、 Ti(IV)、Zr(IV)、Ce(IV)离子的存在促进钒的高度分散和固载。采用三种不同的方法制备了一系列V-(Al/Ti/Zr/Ce)-MCM-41催化剂：1、超快微波一步合成法，2、使用分子复刻版技术改性的后嫁接法，3、对有机硅烷化载体进行部分热处理改性的后嫁接法。通过一系列物理化学技术对合成的催化剂进行了充分表征，特别是对与金属分散度相关的钒的电荷跃迁带的测量和与其对应的光谱带隙蓝移进行了分析。随后，以甲醇作为腐蚀溶剂对合成的钒催化剂进行了金属析出的稳定性测试。通过一种木质素模型化合物1,2-diphenyl-2-methoxyethanol的需氧氧化反应测试了所合成负载型钒催化剂的催化活性。在相同温度及反应条件下，用96通道高通量微反应器技术评价了所制催化剂对该反应的催化性能，筛选出具有最高催化效率的负载型钒催化剂及其最适合的锚定离子。该反应中的碳-碳键裂解反应是木质素降解的最关键也是最困难的步骤之一，可通过这类生物聚合物的降解以清洁的方式生产有用的生物质燃料或生物来源高附加值精细化学品前驱体。

Full textAbstract:
As our long-term companions, dogs’ communication with us is perhaps the most developed of all human- animal ones. This study was aimed to investigate breed differences of German Shepherds and Labradors in dog-human communication. This was obtained through two tests: a problem-solving task and a pointing test. These two tests target both directions of communication: how much dogs understand and respond to the pointing and how they communicate with humans when facing a problem. Additionally, hair cortisol was measured in the dogs and dog owners filled a behavioural questionnaire (C-BARQ). The main breed difference I found was that Labradors performed better in both tests. I also found that the latency of the dogs’ choices in the pointing test correlated with many factors, e.g. they chose quicker when: choosing correctly, when they had many physical contacts with the experimenter in the problem-solving task, when they were more intense, energetic dogs, when they had higher hair cortisol levels and when they had a confident body posture. This indicates that the latency of choice could depend on the confidence of the dog and on the trust in the experimenter as well as on energy level and focus ability. Overall, this study revealed a limited amount of breed differences, compared to a parallel study on Labrador types (hunting and show dogs), showing that intra-breed differences can be more important than inter-breed ones on a behavioural level.

Previous issue date: 2008-09-16The present study had the participation of twenty dogs from the city of Rio de Janeiro being divided in two groups. The group 1 was formed by ten dogs with behaviors disorders anxiety disorders and aggressiveness and group 2 was formed by ten dogs clinically healthful. Owners of all dogs were interviewed guided by a data form containing opened and closed questions organized in four blocks: general aspects, behavior historical, stereotypic or ritualistic behavior and aggressiveness historical. After being classified as able to participate of the study they were submitted to the high dose dexamethasone suppression test to verify if there was a difference in the hypothalamic-pituitary-adrenal axis among the tested groups. No difference on the basal cortisol could be observed (p<0.05) among the two groups. All the individuals were considered suppressors. Therefore the high dose dexamethasone suppression test did not function as a diagnostic tool to confirm the behavioral problem dogs.
O presente estudo teve a participa??o de vinte c?es da cidade do Rio de Janeiro divididos em dois grupos. O grupo um foi formado por dez c?es com dist?rbios comportamentais transtornos da ansiedade e agressividade e o grupo dois foi formado por dez c?es clinicamente saud?veis. Os propriet?rios de todos os c?es foram entrevistados de forma guiada por question?rio estruturado com perguntas abertas e fechadas organizadas em quatro blocos: aspectos gerais, hist?rico comportamental, comportamentos estereotipados ou ritual?sticos e hist?rico de agressividade. Ap?s todos os animais foram submetidos ao teste de supress?o pela dexametasona em alta dose para verificar se havia diferen?a de funcionamento do eixo hipot?lamo-hip?fise-adrenal entre os grupos testados. N?o houve diferen?a significativa (p<0,05) do cortisol basal entre os grupos testados, sendo tamb?m todos os c?es supressores ao teste. Com isso, n?o foi poss?vel diferenciar animais com e sem dist?rbios comportamentais a partir do teste de supress?o alta pela dexametasona.

Roussy, Geneviève. "Rôle du récepteur NTS1 de la neurotensine dans un modèle de douleur tonique." Mémoire, Université de Sherbrooke, 2008. http://savoirs.usherbrooke.ca/handle/11143/3908.
Full textAbstract:
La neurotensine (NT) est un neuropeptide de 13 acides aminés qui fut isolé au début des années 70. Suite à sa découverte, il a été démontré qu'il était localisé autant au niveau central que périphérique et que ses rôles étaient étroitement liés à sa localisation. Pour exercer ses nombreux effets, incluant l'induction d'une analgésie naloxone-indépendante, la NT interagit avec 3 sous-types de récepteurs soit NTS1, NTS2 et NTS3. Jusqu'à maintenant, l'implication du récepteur NTS1 dans l'analgésie induite par la NT a été démontrée uniquement dans des modèles de douleur aiguë. Nous avons donc décidé de caractériser le rôle du récepteur NTS1 1 dans un modèle de douleur tonique, le test à la formaline. Ce test est composé de deux phases actives soit la phase I dite aiguë et la phase II dite inflammatoire. Ces deux phases sont entrecoupées par une interphase où il y a une inhibition active des comportements douloureux. Le test à la formaline permet une analyse rapide et efficace du potentiel analgésique de composés qui pourront être testés ultérieurement en douleur chronique. Lors des études comportementales, nous avons observé que la NT induit un effet analgésiant dose-indépendant. Les comportements douloureux ont diminué jusqu'à 23% dans la phase inflammatoire et ce avec les doses les plus élevées de NT. Pour déterminer plus précisément l'implication du récepteur NTS1 dans l'analgésie induite par la NT, nous avons évalué l'effet de deux agonistes de ce récepteur soit le PD149163 et le NT69L. Ces deux agonistes ont démontré un effet analgésiant plus important que celui de la NT. Avec le PD149163 et le NT69L, l'intensité douloureuse a diminué de façon dose-dépendante jusqu'à 61 et 48% respectivement dans la phase inflammatoire et ce avec les doses les plus élevées utilisées. Pour confirmer les résultats obtenus avec les agonistes du récepteurs NTS1, nous avons co-administré chaque agoniste avec un antagoniste du récepteur NTS1 1, le SR48692. La combinaison du PD149163 et du SR48692 a induit un retour significatif de la douleur chez les animaux traités tandis que la combinaison du NT69L et du SR48692 a renversé partiellement l'effet du NT69L seul. En sachant que le NT69L lie les récepteurs NTS1 1 et NTS2, ces résultats indiquent donc que les récepteurs NTS1 et NTS2 sont à considérer dans l'analgésie observée lors du test à la formaline. Afin de déterminer l'impact cellulaire des agonistes NTS1 lors du test à la formaline, nous avons révélé l'activité neuronale spinale via l'expression de la protéine Fos par la technique d'immunohistochimie. Du côté ipsilatéral à l'injection de formaline, une diminution significative de l'expression de la protéine Fos a été observée avec la NT, le PD149163 et le NT69L au niveau des lamina III-IV et V-VI. Les agonistes du récepteur NTS1 ont aussi eu un effet diminutif dans les lamina I-II en plus d'être les seuls à avoir atténué l'expression de la protéine Fos au niveau des lamina III-IV et VI du côté controlatéral. L'activité neuronale spinale corrèle bien avec les résultats comportementaux obtenus avec les différents composés étudiés. Cette étude nous suggère donc que les agonistes du récepteur NTS1 pourraient représenter une nouvelle voie de composés analgésiques.
