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, CA / There is a need for a capability that enables setup and execution of tests, including integration of new instrumentation into the T&E range environment more rapidly and reliably than with existing methods, and with reduced cost and effort. Moreover, because individual ranges have developed approaches to range control and data distribution which are often range-specific and which call for significant interface development when integrating new instrumentation and systems to the range environment, there is a need to develop a range control and data distribution mechanism that can be reused throughout the T&E community. The purpose of the Next Generation Range Control and Data Distribution (NGRC&DD) project, which is funded by the Test Resource Management Center's (TRMC) Central Test and Evaluation Investment Program (CTEIP), is to develop a capability that modernizes and enhances system control and data distribution in DoD ranges. The Test and Training Enabling Architecture (TENA) is an underlying technology used by NGRC&DD. Migrating to the TENA middleware requires a fundamental reexamination of what data is produced and how it is distributed. TENA offers some tools and mechanisms for ranges that are advantageous relative to traditional methods of data dissemination as well as other versions of middleware available to the community.

ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / Flight and weapons test ranges typically include multiple Telemetry Sites (TM Sites) that receive telemetry from platforms being flown on the range. Received telemetry is processed and forwarded by them to a Range Control Center (RCC) which is responsible for flight safety, and for delivering captured best source telemetry to those responsible for the platform being flown. When range equipment or operations are impaired in their ability to receive telemetry or process it correctly, expensive and/or one-of-a-kind platforms may have to be destroyed in flight to maintain safety margins, resulting in substantial monetary loss, valuable data loss, schedule disruption and potential safety concerns. Less severe telemetry disruptions can also result in missing or garbled telemetry data, negatively impacting platform test, analysis and design modification cycles. This paper provides a high level overview of a physics-compliant Range Test System (RTS) built upon Radio Frequency (RF) Channel Simulator technology. The system is useful in verifying range operation with most range equipment configured to function as in an actual mission. The system generates RF signals with appropriate RF link effects associated with range and range rate between the flight platform and multiple telemetry tracking stations. It also emulates flight and RF characteristics of the platform, to include signal parameters, antenna modeling, body shielding and accurate flight parameters. The system is useful for hardware, software, firmware and process testing, regression testing, and fault detection test, as well as range customer assurance, and range personnel training against nominal and worst-case conditions.

In a growing number of cutting edge centres around the world, radiotherapy treatments delivered by beams of protons and carbon ions offer the opportunity to target tumours with unprecedented conformality. But a sharper dose distribution increases the need for efficient quality control. Treatments are still affected by uncertainties on the penetration depth of the beam within the patient, requiring medical physicists to add safety margins. To reduce these margins and deliver safer treatments, different projects investigate real time range control by imaging prompt gammas emitted along the proton or carbon ion tracks in the patient.<p><p>This thesis reports on the feasibility, development and test of a new type of prompt gamma camera for proton therapy. This concept uses a knife-edge slit collimator to obtain a 1-dimensional projection of the beam path on a gamma camera. It was optimized, using the Monte Carlo code MCNPX version 2.5.0, to select high energy photons correlated with the beam range and detect them with both high counting statistics and sufficient spatial resolution for use in clinical routine. To validate the Monte Carlo model, spectrometry measurements of secondary particles emitted by a PMMA target during proton irradiation at 160 MeV were realised. An excellent agreement with the simulations was observed when using subtraction methods to isolate the gammas in direct incidence. A first prototype slit camera using the HiCam gamma detector was consequently prepared and tested successfully at 100 and 160 MeV beam energies. If we neglect electronic dead times and rejection of detected events, the current solution with its collimator at 15 cm from beam axis can achieve a 1-2 mm standard deviation on range estimation in a homogeneous PMMA target for numbers of protons that correspond to doses in water at Bragg peak as low as 15 cGy at 100 MeV and 25 cGy at 160 MeV assuming pencil beams with a Gaussian profile of 5 mm sigma at target entrance.<p><p>This thesis also investigates the applicability of the slit camera for carbon ion therapy. On the basis of Monte Carlo simulations with the code MCNPX version 2.7.E, this type of camera appears not to be able to identify the beam range with the required sensitivity. The feasibility of prompt gamma imaging itself seems questionable at high beam energies given the weak correlation of secondaries leaving the patient.<p><p>This work consequently concludes to the relevance of the slit camera approach for real time range monitoring in proton therapy, but not in carbon ion therapy. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished

Creating the optimal balance between dialogue level and ambient sound is extremely important in media productions. This process is however inherently difficult due to that people’s requirements and preferences are not uniform. Speech intelligibility is affected by a multitude of factors, such as hearing impairments, audio quality and listening equipment. Recent EU directives on accessibility calls for improved audio clarity features for broadcast content. To accommodate these requirements, the broadcast industry needs to develop functionality for enhanced dialogue clarity and, optimally, put listeners in control of these features. Many speech enhancement techniques exist, this paper uses Sveriges Radio as a case study to evaluate several of these methods. A study on enhancing speech intelligibility through the use of dynamic range control and blind source separation is presented and results show that both methods can have a positive impact. Dynamic range control proves efficient in increasing intelligibility by reducing dynamic variations. It is also well suited to implement in an existing two-channel infrastructure, common in the radio industry, due to being included in novel audio codecs. Blind source separation is found to best be used in moderation due to the risk of audio quality degradation, and is primarily suited for prerecorded material on account of the processing time needed. / Att skapa en optimal balans mellan dialognivå och bakgrundsljud är oerhört viktigt i medieproduktioner. Detta är dock i sig komplicerat på grund av människors olika förutsättningar och preferenser. Taluppfattbarheten påverkas av en mängd faktorer, såsom hörselnedsättningar, ljudkvalitet och lyssningsutrustning. Nya EU-direktiv om tillgänglighet ställer krav på förbättrade funktioner för ljudtydlighet i etermedia. För att tillgodose dessa krav behöver branschen utveckla funktionalitet för ökad dialogtydlighet och företrädesvis också stöd för att lyssnarna själva ska kunna styra dessa funktioner. Det finns många tekniker för att öka taluppfattbarheten, denna artikel använder Sveriges Radio som fallstudie för att utvärdera flera av dessa metoder. En studie om möjligheten till förbättrad taluppfattbarhet genom kontroll av ljudets dynamik (dynamic range control) och blindkallseparation (blind source separation) presenteras, och resultaten visar att båda metoderna kan ha en positiv inverkan. Dynamisk kontroll visar sig vara effektiv för att öka taluppfattbarheten genom att jämna ut dynamiskt innehåll. Tekniken lämpar sig också bra för implementering i en befintlig tvåkanals-infrastruktur, vilket är vanligt inom radioindustrin, på grund av att den inkluderas i nya ljud-kodekar. Blindkallseparation används bäst med måtta på grund av risk for ljudkvalitetsförsämring och är i första hand lämpad för förinspelat material på grund av den processeringstid som behövs.

In zunehmendem Maße werden Kraftfahrzeuge mit Sensoren zur Erfassung des Fahrzeugniveaus, also der Lage des Fahrzeugs relativ zur Straßenoberfläche in Richtung der Fahrzeughochachse, ausgestattet. Informationen zum Fahrzeugniveau werden beispielsweise für die automatische Leuchtweitenregulierung für Gasentladungsscheinwerfer und Fahrwerkregelsysteme benötigt. Mit dem Ziel der Vermeidung wesentlicher Nachteile üblicher Seriensensoren mit Kugelgelenken wurde von der ZF Lemförder Fahrwerktechnik GmbH &amp;amp; Co. KG in Zusammenarbeit mit der Volkswagen AG und der Technischen Universität Dresden ein Fahrzeugniveausensor prototypisch in ein Gummi-Metall-Lager eines Fahrwerklenkers integriert. In diesem mechatronischen System wird mit anisotropen magnetoresistiven (AMR) Sensoren, welche in den Lagerkern integriert sind, die Richtung des Magnetfeldes eines auf der Innenseite der äußeren Lagerhülse angeordneten Perma¬nentmagnetrings gemessen. Ein spezielles Design von Mechanik und Magnetfeld erlaubt die Messung der Lagertorsion als Maß für den vertikalen Radweg des entsprechenden Rades weitgehend unabhängig von kardanischen und translatorischen Lagerverformungen. Diese Dissertation stellt eine Zusammenfassung wesentlicher Inhalte dieses Projektes dar. Einleitend wird die Eignung von Messgröße und Sensorprinzip für die Messung des Fahrzeugniveaus anhand der Anforderungen an Fahrzeugniveausensoren diskutiert und ein optimierter mechanischer Aufbau des Sensorlagers vorgestellt. Den wissenschaftlichen Schwerpunkt dieser Dissertation bildet das Design des Magnetfeldes des erforderlichen Permanentmagneten. Auf der Basis geeigneter Ansätze erfolgt unter Anwendung der Theorie magnetischer Felder die Herleitung eines Feldverlaufs, der ein Optimum hinsichtlich der Unempfindlichkeit gegenüber der sensorischen Erfassung störender Lagerverformungen, der erreichbaren Feldstärke am Sensor, der Signallinearität und der Herstellbarkeit des Permanentmagnetrings darstellt. Zu den weiteren Themen dieser Arbeit zählen die Erörterung der verwendeten Sensorelektronik einschließlich der wesentlichen Software¬algorithmen sowie die Diskussion der experimentell ermittelten Eigenschaften eines Prototyps des Sensorlagers und dessen Komponenten. / In motor vehicles, information on the position of the vehicle in direction of the vehicle height axis in relation to the road surface is increasingly provided by sensors.

In cooperation with Volkswagen AG and University of Technology Dresden, ZF Lemförder Fahrwerktechnik GmbH &amp;amp; Co. KG integrated a vehicle height sensor as a prototype in a rubber mount of an axle link with the aim of avoiding the disadvantages of standard sensors using ball joints. In this mechatronic system, the direction of the magnetic field of a permanent magnetic ring placed on the inside of the outer bearing case is measured by anisotropic magnetoresistive (AMR) sensors integrated in the centre of the bearing. The vertical movement of the relevant wheel is measured via the torsion of the rubber mount. The mechanics and the magnetic field were designed in order to get measurements that are not affected by rotational and linear rubber mount distortions. This thesis works summarizes the key points of this project. The reader will be first introduced to advantages and disadvantages of the measuring quantity and the sensor principle used for measuring the positioning of the vehicle concerning the requirements of vehicle height sensors. In addition, an optimized construction of the sensor rubber mount will be described. The main focus of this work is the design of the magnetic field of the required permanent magnet. While considering adequate approaches, the magnetic field of this magnet is formulated from the theory of magnetic fields. The presented magnetic field is an optimisation in terms of the insensitivity of sensoric measurements towards interferic rubber mount distortions, the field force that can be accomplished at the sensor, the linearity of the signal and the producibility of the permanent magnet ring. Further topics that are addressed in this thesis are the discussion of the used sensor electronic including essential software algorithms and the discussion of the experimentally derived characteristics of the prototype of the sensor rubber mount and its components.
