International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / In the past few years, GPS has proven itself as an effective source of time space position information (TSPI) data for air vehicles. Currently, GPS truth systems are used to track aircraft ranging from low dynamic vehicles to high dynamic fighters. However, low-cost GPS TSPI instrumentation is not currently available for stores and weapons delivered by air vehicles. To date, data is collected by tracking dropped items using radar or optical means. This process is costly and time consuming. The purpose of this project is to leverage the recent advances in micro-electromechanical systems (MEMS) technology to develop a subminiature, inexpensive, low power, disposable telemetrytransmitting package. The purpose of this transmitting package is to up-link the GPS positional data from the weapon or store to the host aircraft. This data is then retransmitted by the host aircraft to a ground station and/or recorded on board for post processing. The transmission of the data to the host aircraft can provide near real- time position data for the released object. The transmitting package must have a unique identification method for application in tracking multiple objects. Since most of the systems used in weapons testing will be destroyed, it is extremely important to keep the development and maintenance cost low. In addition, the package must be non-intrusive to avoid any significant modification to the weapon and to facilitate quick instrumentation of the weapon for test and evaluation.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In this paper, we propose a receiver design for satellite ground station use which can demodulate a waveform without specific knowledge of the data rate, convolutional code rate, or line code used. Several assumptions, consistent with the Space Network operating environment, are made including only certain data rates, convolutional code rates and generator polynomials, and types of line encoders. Despite the assumptions, a wide class of digital signaling (covering most of what might be seen at a ground station receiver) is captured. The approach uses standard signal processing techniques to identify data rate and line encoder class and a look up table with coded sync words (a standard feature of telemetry data frame header) in order to identify the key parameters. As our research has shown, the leading bits of the received coded frame can be used to uniquely identify the parameters. With proper identification, a basic receiver autoconfiguration sequence (date rate, line decoder, convolutional decoder) may be constructed.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Transducers have traditionally been incorporated into data systems by connecting the transducer to a signal conditioner that is then connected to a multiplexer with an Analog-to-Digital Converter (ADC). The signal conditioning, multiplexer and the ADC are usually included within the same assembly that is called a Data Acquisition Unit (DAU) or an encoder. A network centric data system allows the same architecture to be used if the interface to the encoder is changed to be a network interface. However, a network centric architecture allows other options as well. The signal conditioning and ADC can be included within the same package as the transducer and the assembly can be interfaced to the network. When this is combined with the processing capability now available, a whole new range of possibilities present themselves. The transducer can now be digitally processed to provide a linear output, it can be converted to Engineering Units, digitally filtered or have a host of other functions performed within the housing that contains the transducer. However, the network centric approach does not produce these advantages without some disadvantages. The major problem that needs to be solved is how we time stamp the data. With the encoder we could time stamp the PCM frame and be able to determine the time that a sample was taken from that information. Even in systems that convert the encoder to have a network interface, the time stamp needs to be affixed to the data in the encoder. With a network centric approach, the sample can be taken in the transducer and how to time stamp it becomes a real problem. This is a problem that must be considered at the system level. Some method of making time available at a low enough level in the system to allow transducer outputs to be time stamped is either a network issue or it requires a separate interface.

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, NV / Among the rich infrastructure of a Telemetry/Ground Station Center dwells the subset dedicated to radio communications. Radios are mainly used to communicate with the aircraft under test in order to give guidance and feedback from ground specialists. Sometimes, however, radios themselves become the subject of the test, requiring a full set of them with all their features and capabilities (Military Modes, HF ALE, SELCAL, etc). Remote control (and audio routing) of these radios is a critical as infrastructures scale over tens of radios, distributed amid different test centers separated by hundreds of kilometers. Addition of a remote touch user interface, MIL COMSEC and TRANSEC modes, automatic audio routing, together with a maintenance free requirement, makes the whole issue far more difficult to manage. Airbus Defense & Space has developed a Smart Radio Control System allowing to profit from those advantages and more benefits: *Intuitive Touch UI *Automatic Audio Routing *Distributed infrastructure (network based) *Autonomous and service free (no one, other than FTC needed to operate it) *Heterogeneous (any radio can be controlled by creating a plug & play library) *Special Modes support (COMSEC, TRANSEC, HF ALE, and SELCAL) Future additions will include, amongst others, VoIP integration and tablet use.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Current legacy acquisition systems such as the Advanced Airborne Test Instrumentation System (AATIS) are custom-built to each individual application with unique sensors and data modules. Replacing, adding, or subtracting sensors requires the system to be removed from service for days, weeks, or even months. This is a result of having to route special wires to each sensor and reprogramming the system with sensor information, calibration data, etc. AR sensor information must be contained in the main system since these systems do not have intelligence at the sensor level. If sensors were to contain information in their own IEEE 1451-compliant transducer electronic data sheet (TEDS), the main system would no longer have to be reprogrammed with this information. This information could then be obtained directly from the sensors when they are inserted into the system. A plug-n-play capability is being added to the system with the development of a standard interface to the system control unit (SCU). This interface, called a Multi-Network Capable Applications Processor (Multi-NCAP), will interface IEEE 1451-compliant smart transducer interface modules (STIMs) to the SCU in the AATIS as well as other legacy systems. With this development, maintenance and new configuration times for the AATIS and other legacy systems will be significantly reduced.

Many mobility impaired users are unable to operate a powered wheelchair safely, without causing harm to themselves, others, and the environment. Smart wheelchairs that assist or replace user control have been developed to cater for these users, utilising systems and algorithms from autonomous robots. Despite a sustained period of research and development of robotic wheelchairs, there are very few available commercially. This thesis describes work towards developing a navigation system that is aimed at being retro-fitted to powered wheelchairs. The navigation system developed takes a systems engineering approach, integrating many existing open-source software projects to deliver a system that would otherwise not be possible in the time frame of a master's thesis. The navigation system introduced in this thesis is aimed at operating in an unstructured indoor environment, and requires no a priori information about the environment. The key components in the system are: obstacle avoidance, map building, localisation, path planning, and autonomously travelling towards a goal. The test electric wheelchair was instrumented with the following: a laptop, a laser scanner, wheel encoders, camera, and a variety of user input methods. The user interfaces that have been implemented and tested include a touch screen friendly graphical user interface, keyboard and joystick.

Syftet med denna uppsats är att studera begreppen urban sprawl och Smart Growth utifrån ett hållbarhetsperspektiv, samt att undersöka vad dessa begrepp innebär för utvecklingen av den amerikanska stadsplaneringen också för de amerikanska städernas utformning. Urban sprawl innebär en utglesning av städer, något som i stor utsträckning har skett i USA sedan bilismens ökade framfart under 1950-talet. Smart Growth är ett ideal som förespråkar motsatsen till sprawl, det vill säga tätare städer där bilens roll blir mindre och mer utrymme ges åt gångare och cyklister. För idealet finns tio stycken principer som ska göra Smart Growth till verklighet. Utifrån dessa principer har jag - med hjälp av en kvalitativ textanalys - undersökt översiktsplaner från fem stycken amerikanska städer. Målet med analysen var att se i vilken utsträckning Smart Growth redovisades inom den amerikanska stadsplaneringen. Resultatet visade att principerna för Smart Growth presenterades i bred utsträckning i fyra av dem fem undersökta planerna. Detta för att det finns goda skäl att tro att den amerikanska stadsplaneringen kommer att sträva mot en tätare stadsbild. Trots detta är det inte säkert att urban sprawl kommer att försvinna. Slutsatsen är således att både urban sprawl och Smart Growth förmodligen kommer att karaktärisera den amerikanska stadsplaneringen under de kommande decennierna.

Demand participation is a basic ingredient of the next generation of power exchanges in electricity markets. A key challenge in implementing demand response stems from establishing reliable market frameworks so that purchasers can estimate the demand correctly, buy as economically as possible and have the means of hedging the risk of lack of supply. System operators also need ways of estimating responsive load behaviour to reliably operate the grid. In this context, two aspects of demand response are addressed in this study: scheduling and baseline estimation. The thesis presents a market clearing algorithm including demand side reserves in a two-stage stochastic optimization framework to account for wind power production uncertainty. The results confirm that enabling the load to provide reserve can potentially benefit consumers by reducing electricity price, while facilitating a higher share of renewable energy sources in the power system. Two novel methods, Bayesian Linear regression and Kernel adaptive filtering, are proposed for baseline load forecasting in the second part of the study. The former method provides an integrated solution for prediction with full accounting for uncertainty while the latter provides an online sequential learning algorithm that is useful for short term forecasting. / Graduate / 0544 / nimahtehrani@gmail.com

If gutta-percha cartridges are contaminated with bacteria prior to obturation then contamination of the root canal system may result. Successful treatment not only depends on bacterial elimination but also depends on prevention of recontamination. This study was motivated by the observation that endodontists frequently use single use gutta-percha cartridges on multiple patients. The goal of this study was to determine if cross contamination occurred when a single gutta-percha cartridge in the Calamus™ Flow System was used on multiple patients. An effective recovery method was established during a pilot study using Enterococcus faecalis as a sample bacterium. Microbial recovery was obtained using standard media. The Calamus™ heated gutta-percha delivery system was evaluated to determine the percentage of cartridges with recoverable microorganism under four conditions. Results showed that for cartridges tested immediately after removal from manufacturer’s packaging, the observed negative outcome was 0/10 (0%). For cartridges used on a single patient with an alcohol wipe after use, the negative outcome was 0/20 (0%). For cartridges used on a single patient with no alcohol wipe after use, the negative outcome was 1/20 (5%). For cartridges used on three patients with an alcohol wipe after each use, the number of observed negative outcomes was 0/20 (0%). Using 95% score confidence intervals, the results indicate that the percentage of cartridges with recoverable microorganism under the four conditions is below 27.8% for cartridges sampled from manufacturer’s packaging, 16.1% for cartridges used on a single patient with a alcohol wipe after use, 23.6% for cartridges used on a single patient with no alcohol wipe after use, and 16.1% for cartridges used on three patients with an alcohol wipe after each use. Evidence from this study indicates using Calamus™ flow cartridges on multiple patients vs. single patient does not lead to an increased contamination risk.
