International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Over a dozen commercial remote sensing programs are currently under development representing billions of dollars of potential investment. While technological advances have dramatically decreased the cost of building and launching these satellites, the cost and complexity of accessing their data for commercial use are still prohibitively high. This paper describes Reconfigurable Gateway Systems which provide, to a broad spectrum of existing and new data users, affordable telemetry data acquisition, processing and distribution for real-time remotely sensed data at rates up to 300 Mbps. These Gateway Systems are based upon reconfigurable computing, multiprocessing, and process automation technologies to meet a broad range of satellite communications and data processing applications. Their flexible architecture easily accommodates future enhancements for decompression, decryption, digital signal processing and image / SAR data processing.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / Measurement of vibration and acoustic signals at various locations in the launch vehicle is important to establish the vibration and acoustic environment encountered by the launch vehicle during flight. The vibration and acoustic signals are wideband and require very large telemetry bandwidth if directly transmitted to ground. The DSP based Signal Processing Unit is designed to measure and analyse acoustic and vibration signals onboard the launch vehicle and transmit the computed spectrum to ground through centralised baseband telemetry system. The analysis techniques employed are power spectral density (PSD) computations using Fast Fourier Transform (FFT) and 1/3rd octave analysis using digital Infinite Impulse Response (IIR) filters. The programmability of all analysis parameters is achieved using EEPROM. This paper discusses the details of measurement and analysis techniques, design philosophy, tools used and implementation schemes. The paper also presents the performance results of flight models.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Advanced Telemetry Processing System (ATPS) is the result of a joint development project between Harris Corporation and Veda Systems, Incorporated. The mission of the development team was to produce a high-performance, cost-effective, supportable telemetry system; one that would utilize commercial-off-the-shelf (COTS) hardware and software, thereby eliminating costly customization typically required for range and telemetry applications. A critical element in the 'cost-effective, supportable' equation was the ability to easily incorporate system performance upgrades as well as future hardware and software technology advancements. The ATPS combines advanced hardware and software technology that includes a high-speed, top-down data management environment; a mature man-machine interface; a B1-level Trusted operating system and network; and stringent real-time multiprocessing capabilities into a single, fully integrated, 'open' platform. In addition, the system incorporates a unique direct memory transfer feature that allows incoming data to pass directly into local memory space where it can be displayed and analyzed, thereby reducing I/O bottleneck and freeing processors for other specialized tasks.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A digital feedback system used to monitor and control a high energy electron beam’s orbit and stability in a VUV and X-ray storage ring will realize a 10 fold increase in the feedback system response time using packetized (IRIG 107-98) telemetry. The improvement in feedback time will provide a significant improvement in the level of orbit stability. This paper discusses the advantages of using a packetizing standard and high speed data acquisition as a cost effective way to support the scientific community in their real time processing needs.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The NASA GSFC’s Wallops Flight Facility’s (WFF) Mobile Range Control System (MRCS) is based on the functionality of the WFF Range Control Center at Wallops Island, Virginia. The MRCS provides real time instantaneous impact predictions, real time flight performance data, and other critical information needed by mission and range safety personnel in support of range operations at remote launch sites. The MRCS integrates a PC telemetry processing system (TELPro), a PC radar processing system (PCDQS), multiple Silicon Graphics display workstations (IRIS), and communication links within a mobile van for worldwide support of orbital, suborbital, and aircraft missions. This paper describes the MRCS configuration; the TELPro’s capability to provide single/dual telemetry tracking and vehicle state data processing; the PCDQS’ capability to provide real time positional data and instantaneous impact prediction for up to 8 data sources; and the IRIS’ user interface for setup/display options. With portability, PC-based data processing, high resolution graphics, and flexible multiple source support, the MRCS system is proving to be responsive to the ever-changing needs of a variety of increasingly complex missions.

The intent of this dissertation is to generate a set of non-dominated finite-memory policies from which one of two agents (the leader) can select a most preferred policy to control a dynamic system that is also affected by the control decisions of the other agent (the follower). The problem is described by an infinite horizon total discounted reward, partially observed Markov game (POMG). Each agent’s policy assumes that the agent knows its current and recent state values, its recent actions, and the current and recent possibly inaccurate observations of the other agent’s state. For each candidate finite-memory leader policy, we assume the follower, fully aware of the leader policy, determines a policy that optimizes the follower’s criterion. The leader-follower assumption allows the POMG to be transformed into a specially structured, partially observed Markov decision process that we use to determine the follower’s best response policy for a given leader policy. We then present a value determination procedure to evaluate the performance of the leader for a given leader policy, based on which non-dominated set of leader polices can be selected by existing heuristic approaches. We then analyze how the value of the leader’s criterion changes due to changes in the leader’s quality of observation of the follower. We give conditions that insure improved observation quality will improve the leader’s value function, assuming that changes in the observation quality do not cause the follower to change its policy. We show that discontinuities in the value of the leader’ criterion, as a function of observation quality, can occur when the change of observation quality is significant enough for the follower to change its policy. We present conditions that determine when a discontinuity may occur and conditions that guarantee a discontinuity will not degrade the leader’s performance. This framework has been used to develop a dynamic risk analysis approach for U.S. food supply chains and to compare and create supply chain designs and sequential control strategies for risk mitigation.

International Telemetering Conference Proceedings / October 13-16, 1986 / Riviera Hotel, Las Vegas, Nevada / The Boeing Commercial Airplane Company presently uses an Airborne Data Analysis and Monitor System (ADAMS) to support extensive qualification testing on new and modified commercial aircraft. The ADAMS system consists of subsystems controlled by independent processors which preprocess serial PCM data, perform application-specific processing, provide graphic display of data, and manage mass storage resources. Setup and control information is passed between processors using the Ethernet protocol on a fiber optic network. Tagged data is passed between processors using a data bus with networking characteristics. During qualification tests, data are dynamically selected, analyses performed, and results recorded. Decisions to proceed or repeat tests are made in real time on the aircraft. Instrumentation in present aircraft includes up to 3700 sensors, with projections for 5750 sensors in the next generation. Concurrently, data throughput rates are increasing, and data preprocessing requirements are becoming more complex. Fairchild Weston Systems, Inc., under contract to Boeing, has developed an Acquisition Interface Assembly (AIA) which accepts multiple streams of PCM data, controls recording and playback on analog tape, performs high speed data preprocessing, and distributes the data to the other ADAMS subsystems. The AIA processes one to three streams in any of the standard IRIG PCM formats using programmable bit, frame and subframe synchronizers. Data from ARINC buses with embedded measurement labels, bus ID’s, and time tags may also be processed by the AIA. Preprocessing is accomplished by two high-performance Distributed Processing Units (DPU) operating in either pipeline or parallel environments. The DPU’s perform concatenation functions, number system conversions, engineering unit conversions, and data tagging for distribution to the ADAMS system. Time information, from either a time code generator or tape playback, may be merged with data with a 0.1 msec resolution. Control and status functions are coordinated by an embedded processor, and are accessible to other ADAMS processors via both the Ethernet interface and a local operator’s terminal. Because the AIA assembly is used in aircraft, the entire functional capability has been packaged in a 14-inch high, rack-mountable chassis with EMI shielding. The unit has been designed for high temperature, high altitude, vibrating environments. The AIA will be a key element in aircraft qualification testing at Boeing well into the next generation of airframes, and specification, design, development, and implementation of the AIA has been carried out with the significance of that fact in mind.

Thesis (PhD (Microbiology))--University of Stellenbosch 2010. / ENGLISH ABSTRACT: Two isogenic plasmids, pRAS3.1 (11,851-bp) and pRAS3.2 (11,823-bp), were identified as tetracycline resistance plasmids occurring within Aeromonas salmonicida subsp. salmonicida and atypical A. salmonicida subsp. salmonicida strains that were isolated from salmon aquaculture farms in Norway (L'Abee-Lund and Sorum, 2002). Although sequence analysis showed that, except for the repC gene, the replication and mobilization genes of the two pRAS3 plasmids are similar to that of the two IncQ-2 plasmids pTF-FC2 and pTC-F14, incompatibility testing during the course of this study revealed that the replicons of the two pRAS3 plasmids were compatible with the replicons of the IncQ-1α, ß] and y plasmids RSF1010, pIE1107 and pIE1130, as well as with the IncQ-2α and ß plasmids, pTF-FC2 and pTC-F14, respectively. Through sequence analysis it was suggested that the repC gene of the ancestral pRAS3 plasmid was probably acquired during a gene exchange event with a yet to be identified plasmid. The difference in the RepC of the pRAS3 plasmids compared to that of the other IncQ-like plasmids against which the pRAS3 plasmids were tested for incompatibility was thus suggested to be a likely reason for the compatibility of the two pRAS3 plasmid replicons with these IncQ-1 and IncQ-2 plasmids. Two previously unidentified genes, encoding two small 108 and 74-aa proteins distantly related to the PemIK (Bravo et al., 1987; Tsuchimoto et al., 1988) and MazEF (Masuda et al., 1993) TA systems, were found to be present between repB and repA genes of the two pRAS3 plasmids. Cloning of these two genes onto an unstable pOU82-test vector increased the stability of the vector from 35 to 98% after ~72 generations, thus suggesting that like the PasABC and PasAB systems of pTF-FC2 and pTC-F14, these two genes encode proteins which function as a toxin-antitoxin (TA) system. Although located in a similar position on the plasmids, the TA system of the two pRAS3 plasmids and the Pas systems of pTF-FC2 and pTC-F14 are unrelated, suggesting that these two types of TA systems were acquired independently from each other. Based on the sequence similarity and genetic organization of pRAS3 compared to the IncQ-2α and ß] plasmids pTF-FC2 and pTC-F14, respectively, but given that the pRAS3 plasmids were compatible with both pTF-FC2 and pTC-F14, as well as other IncQ-like plasmids, it was suggested that the two pRAS3 plasmids be classified into a new IncQ-2y subgroup. A comparison of the sequences of the two pRAS3 plasmids to each other by L'Abee-Lund and Sorum (2002) revealed that, apart from a number of point mutations within the tetAR tetracycline resistance genes of the two plasmids, the only other differences between them are that pRAS3.1 has 4 tandem copies of 22-bp iteron repeats within its origin of vegetative replication (oriV), and 5 tandem copies of CCCCCG 6-bp repeats near the origin of transfer (oriT), while pRAS3.2 has only three and four copies of each of the two repeated sequences, respectively. As the two pRAS3 plasmids are likely to have arisen from the same ancestor, this raised the question of how the copy numbers of these two different types of repeat sequences affected the ability of pRAS3.1 and pRAS3.2 plasmids to compete within a host cell as well as within a population of host cells, and therefore, why both of these isogenic plasmids have managed to persist in the environment. The plasmid copy numbers (PCN) of pRAS3.1 and pRAS3.2 were estimated to be 45 ± 13 and 30 ± 5 plasmids per chromosome, respectively. By creating a series of pRAS3.1 derivative plasmids with 3 to 7 copies of the 22-bp iterons and 4 or 5 copies of the 6-bp repeats, it was shown that an increase in the number of iterons brought about a decrease in PCN, probably due to an increased ability to bind RepC, while an increase in the number of 6-bp repeats from 4 to 5 brought about an increase in repB transcription, and the higher levels of RepB resulted in an increase in PCN. Thus the reason for pRAS3.1 having a ~1.5-fold higher PCN than pRAS3.2, even though it has 4 x 22-bp iterons compared to the 3 x 22-bp iterons of pRAS3.2, was that it had a higher level of repB transcription due to having 5 x 6-bp repeats in its mobB-mobA/repB promoter region compared to the 4 x 6-bp repeats of pRAS3.2. The differences in the number of iterons and 6-bp repeats, and hence PCN, did not have an effect on the stability of the two wild type (WT) plasmids or their derivatives even when the TA system was neutralized by having a copy of the TA genes present on a vector in trans and it was argued that the relatively high PCN of the two pRAS3 plasmids was sufficient to ensure plasmid stability through random distribution. As the two pRAS3 plasmids were mobilized at similar frequencies difference in PCN and mobB-mobA/repB transcription did not seem to affect their mobilization frequency. When pRAS3.1 and pRAS3.2 were competed intracellularly as coresident plasmids, pRAS3.1 was able to displace pRAS3.2 from 98% of the host cells within ~20 generations. The displacement of pRAS3.2 by pRAS3.1 was found to be as a result of pRAS3.1 having 4 x 22-bp iterons, which enabled pRAS3.1 to titrate of the communal pool of available RepC initiator proteins. Plasmids with 5 or 7 x 22-bp iterons, were however less effective at displacing a plasmid with 3 iterons, and it was speculated that plasmids with more than 4 x 22-bp iterons within their oriV were less successful at initiating replication than was a plasmid with 3 iterons within its oriV. A direct correlation was found between the PCN of a pRAS3 plasmid and the metabolic burden it imposed on its host. Thus pRAS3.1, as a result of its ~1.5-fold higher PCN than pRAS3.2 placed a small but significantly higher (~2.8%) metabolic load on its host compared to pRAS3.2. It was concluded that pRAS3.1 had a competitive advantage over pRAS3.2 when these plasmids were coresident within a single host (as would have been when the two plasmids first diverged from each other) as it was able to displace pRAS3.2. However, as a result of pRAS3.2 having a lower PCN, it placed a smaller metabolic burden on an isogenic host and this resulted in pRAS3.2 having an advantage over pRAS3.1 at the population level. Sequence remnants of pRAS3.2 from horizontal gene transfer suggested that pRAS3.2 was the original pRAS3 plasmid and thus that pRAS3.1 evolved from pRAS3.2. As the pRAS3.1 derivative plasmids that were constructed during the course of this study are likely to have been intermediates in the evolution of pRAS3.1 from pRAS3.2, I was able to speculate on the stepwise evolution of pRAS3.1 from pRAS3.2 based on the characteristics of these plasmids, and thus, how both macro- and microevolutionary events have contributed to the evolution of these two plasmids. / AFRIKAANSE OPSOMMING: Die twee isogeniese plasmiede, pRAS3.1 en pRAS3.2, was geidentifiseer as tetrasiklien weerstandbiedende plasmiede wat in Aeromonas salmonicida subsp. salmonicida en nie-tipiese A. salmonicida voorkom (L'Abee-Lund and Sorum, 2002). DNS volgorde analise deur L'Abee-Lund en Sorum (2002) het gewys dat die gene verantwoordelik vir replisering (uitsluitend die repC) en mobililisering naverwant is aan die van twee IncQ-2 plasmiede, pTF-FC2 en pTC-F14. Eksperimente tydens hierdie studie het egter gewys dat die repliserende sisteme van die twee pRAS3 plasmiede versoenbaar is met die repliserende sisteme van die IncQ-1α, ß and y plasmiede RSF1010, pIE1107 en pIE1130, sowel as die IncQ-2α en ß plasmiede, pTF-FC2 and pTC-F14, onderskeidelik. Analise van die aminosuur volgorde van die pRAS3 RepC proteien het gedui daarop dat die proteien taamlik verskil van die RepC proteiene van die naverwante plasmiede pTF-FC2 en pTC-F14, sowel as die van die IncQ-1 tipe plasmiede, en daar was voorgestel dat die voorsaat pRAS3 plasmied moontlik die repC geen bekom het vanaf 'n ander, nog onbekende, plasmied deur middel van horisontale geen uitruiling. Die verskil in die RepC van die pRAS3 plasmiede teenoor die van die ander IncQ plasmiede waarteen hulle getoets was vir onversoenbaarheid, was waarskynlik die rede waarom die pRAS3 plasmiede versoenbaar was met die IncQ-1 en IncQ-2 plasmiede. DNS volgorde analise tydens hierdie studie het die teenwoordigheid van twee, vantevore ongeidentifiseerde, klein 108 en 74 aminosuur proteiene onthul wat ver langs verwant is aan die PemIK (Bravo et al., 1987; Tsuchimoto et al., 1988) en MazEF (Masuda et al., 1993) toksien-antitoksien sisteme. Die gene wat kodeer vir hierdie toksien-antitoksien proteine kom tussen die repB en die repA gene van die twee pRAS3 plasmiede voor. Klonering van die toksien-antitoksien gene van die pRAS3 plasmiede op 'n ander onstabiele plasmied het die stabiliteit van hierdie plasmied verhoog van 35 tot en met 98% na ~72 generasies. Hierdie experiment het dus bevestig dat, soos die PasABC en PasAB sisteme van pTF-FC2 en pTC-F14 onderskeidelik, die twee gene 'n toksien-antitoksien sisteem kodeer wat die stabiliteit van 'n plasmied binne 'n bakteriese populasie kan verbeter. Alhoewel die toksien-antitoksien gene van pRAS3 op 'n soortgelyke posisie op die pRAS3 plasmiede voorkom as wat die pasABC en pasAB gene op hulle onderskeidelike pTF-FC2 en pTC-F14 plasmiede voorkom, is hulle nie verwant nie en dus was dit voorgestel dat die twee tipe toksien-antitoksien sisteme onafhanklik van mekaar verkry is. Aangesien die DNS volgorde en genetiese rangskikking van pRAS3 teenoor die IncQ-2α en ß plasmiede pTF-FC2 en pTC-F14, onderskeidelik, soortgelyk is, asook die feit dat die pRAS3 plasmiede versoenbaar was met pTF-FC2 en pTC-F14, sowel as ander IncQ tipe plasmiede, word dit voorgestel dat die twee pRAS3 plasmiede in 'n nuwe IncQ-2y subgroep ingedeel word. 'n Vergelyking van die DNS volgorde van die twee pRAS3 plasmiede deur L'Abee-Lund and Sorum (2002) het gewys dat, behalwe vir 'n paar puntmutasies binne die tetAR tetrasiklien weerstandsgene, verskil die twee net in die opsig dat pRAS3.1 het 4 agtereenvolgende kopiee van 22-bp 'iteron' herhalings wat gelee is binne sy replikasie oorsprong en 5 kopiee van 'n CCCCCG 6-bp herhaling wat naby sy oorsprong van oordrag gelee is, terwyl pRAS3.2 net 3 en 4 kopiee het van elk van die onderskeie volgorde herhalings. Dus die bestaan van twee plasmiede met verskillende kopiegetalle van die twee verskillende tipe DNA volgorde herhalings, maar wat vermoedelik afkomstig is vanaf dieselfde stam plasmied, bring die volgende oorhoofse vrae aangaande die plasmiede na vore: hoe beinvloed die DNS volgorde herhalings die vermoe van die twee plasmiede om binne 'n enkele gasheersel te kompeteer vir die beskikbare plasmied repliserings masjinerie, en hoe beinvloed dit die plasmied-gasheersel verhouding en dus hulle vermoe om te kompeteer op die populasie vlak, en laastens, hoekom het beide weergawes van die plasmied bly voortbestaan in die omgewing? Die plasmied kopiegetalle van pRAS3.1 en pRAS3.2 was eksperimenteel beraam by ongeveer 45 ± 13 en 30 ± 5 plasmiede per chromosoom in E. coli, onderskeidelik. Deur 'n reeks van pRAS3.1 derivate te skep met 3 tot 7 'iteron' herhalings en 4 of 5 kopiee van die 6-bp herhalings was dit bewys dat 'n toename in die hoeveelheid 'iterons' 'n afname in die plasmied kopiegetal veroorsaak, vermoedelik deur 'n verbeterde vermoe om RepC te bind, terwyl 'n verhoging van 4 tot 5 kopiee van die 6-bp herhaling 'n afname in die kopiegetal te weeg gebring het. Die repB geen van 'n plasmied met 5 x 6-bp herhalings was ~2-voud hoer uitgedruk as die van 'n plasmied met 4 x 6-bp herhalings, en dit was verder bewys dat 'n verhoogde vlak van repB transkripsie vanaf 'n L-arabinose induseerbare promoter in trans van 'n pRAS3 plasmied met 4 x 6-bp herhalings het 'n ~2-voud verhoging in plasmied kopiegetal teweeg gebring. Die rede dat pRAS3.1 'n ~1.5-voud hoer plasmied kopiegetal gehad het as pRAS3.2, was as gevolg van 'n hoer vlak van repB uitdrukking weens die feit dat pRAS3.1 5 x 6-bp herhalings in die mobB-mobA/repB promoter area het terwyl pRAS3.2 net 4 van die 6-bp herhalings in dieslefde posisie het. Sou pRAS3.1 4 x 22-bp 'iterons' gehad het, maar saam met 4 x 6-bp herhalings soos pRAS3.2, dan sou die plasmied kopiegetal 23 ± 2 plasmiede per chromosoom gewees het. Die verskil in die hoeveelheid 'iterons' en 6-bp herhalings, en dus die plasmied kopiegetal, het nie 'n effek op die stabiliteit van die wilde tipe plasmiede of hulle derivate gehad nie, selfs al was die toksien-antitoksien sisteem geneutraliseer deurdat daar 'n kopie van die toksien-antitoksien sisteem op 'n ander plasmied in trans van die pRAS3 plasmiede en hul derivate geplaas was. Die relatiewe hoe plasmied kopiegetal van die pRAS3 plasmiede, wat moontlik hoog genoeg was om plasmied stabiliteit deur middel van toevallige uitdeling te verseker, was voorgestel as die rede vir die hoe mate van plasmied stabiliteit. Soortgelyke frekwensies van mobilisasie vir pRAS3.1 en pRAS3.2 (0.032 ± 0.014 en 0.021 ± 0.013 transkonjugate per donateur, onderskeidelik) was waargeneem. Dus het dit geblyk dat die verskil in uitdrukking van die mobB-mobA/repB operon, sowel as die plasmied kopiegetal van die twee pRAS3 plasmiede, nie die mobiliserings frekwensie beinvloed het nie. Intrasellulere kompetisie tussen pRAS3.1 en pRAS3.2 het gewys dat pRAS3.1 die vermoe gehad om binne ~20 generasies pRAS3.2 vanuit 98% van die gasheerselle te skop. Daar was gewys dat die teenwoordigheid van 4 x 22-bp 'iterons' in die oorsprong van replikasie van pRAS3.1 die rede was vir die vermoe van hierdie plasmied om pRAS3.2 uit te kompeteer binne die gasheersel, moontlik deurdat die 4 x 22-bp 'iterons' beter in staat was om die RepC protein te bind. Die vermoe van plasmiede met 5 of 7 x 22-bp 'iterons' om te kompeteer met 'n plasmied met net 3 x 22-bp 'iterons' was toenemend swakker in vergelyking met die van 'n plasmied met 4 x 22-bp 'iterons', en hierdie waarneming het gelei tot die voorstel dat plasmiede met meer as 4 x 22-bp 'iterons' nie so suksesvol was om replikasie te inisieer soos ¡¥n plasmied met 3 x 22-bp 'iterons' nie. 'n Direkte korrelasie was gevind tussen die plasmied kopiegetal van 'n pRAS3 plasmied en die metaboliese lading wat die plasmied op die gasheersel geplaas het. Dus het pRAS3.1, met 'n plasmied kopiegetal van ~1.5-voud hoer as die van pRAS3.2, 'n effens hoer (~2.8%) metababoliese lading op die gasheersel as pRAS3.2 geplaas. In gevolge van die inter- en intrasellulere kompetiesie eksperimente, was dit ge-argumenteer dat pRAS3.1 'n mededingende voordeel bo-oor pRAS3.2 binne 'n gasheersel (soos wat dit sou gewees het kort nadat die twee plasmiede van mekaar uiteengevloei het) gehad het omdat dit in staat was om pRAS3.2 vanuit die gasheersel te skop. Aan die ander kant het pRAS3.2 'n laer plasmied kopiegetal en dus 'n laer metaboliese lading op die isogeniese gasheersel geplaas het, en daardeur het pRAS3.2 weer op die populasievlak die kompeterende voordeel bo-oor pRAS3.1 gehad. Die eienskappe van pRAS3.2 was meer soortgelyk aan die van ander IncQ-tipe plasmiede as wat die eienskappe van pRAS3.1 was, en dus word dit voorgestel dat pRAS3.1 vanaf pRAS3.2 afkomstig was. Omdat die derivaat plasmiede wat geskep was vanaf pRAS3.1 tydens hierdie studie moontlike tussengangers in die ontwikkeling van pRAS3.1 vanaf pRAS3.2 was, kan gespekuleer word, gebaseer op die eienskappe van hierdie plasmiede, oor die “stapsgewyse manier” waarmee pRAS3.1 vanaf pRAS3.2 ge-evolueer het, en dus hoe beide makro- en mikro-evolusionere gebeurlikhede bygedra het tot die evolusie van genoemde plasmiede.

ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / Nowadays, with the development of the electronics, a video camera can produce hi-resolution and hi-speed images with a very good sensitivity. A typical application is the execution of the Air Data System (ADS) Calibration Flight Test Campaign (FTC) using the Tower-Fly-By method, where the aircraft reference altitude is computed from video frames. To improve efficiency, safety and effectiveness for this FTC, the Flight Test Research Institute (IPEV) developed a near real-time video processing application to compute the aircraft altitude from 720i video frames at up to 400 fps. This development was executed as Master Science dissertation along with Itajubá State University (UNIFEI). Tests results demonstrated satisfactory performance for this tool compared to Ground Telemetry System (GTS) and Global Positioning System (GPS).
