Low Cost Vector Scoring System for Airborne TargetsWhiteman, Don, Bradley, Joe 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / Testing of airborne weapons systems often requires that a scoring system be placed on the target drone to obtain critical miss distance data. Advanced weapons utilizing directional warheads often require a scoring system which yields vector, miss distance and miss direction, information. Scalar scoring systems currently in use are relatively simple and inexpensive. Vector scoring systems are typically complex and the cost of systems which are currently available or are being developed can be prohibitively expensive. Due to the current military budget decline, development of a low cost vector scoring system is desirable This paper introduces a low cost vector scoring system developed for airborne target drones and based on an inexpensive scalar scoring system currently in use. To meet the low cost criteria, vector operation is achieved via minimal modifications to the existing scalar system.

A Dielectric Resonator Stabilized Frequency Modulation Oscillator in the S-BandBanghua, Zhou, Mingsheng, Huang 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / With the development of the airborne telemetry technique, it will be demanded that the transmitting sets on the missiles are more reliable and smaller. A frequency modulation (FM) oscillator stabilized with a dielectric resonator (DR), which can operates in the S-band directly, is presented. The FM oscillator is of simple circuit, reliable operation in the stabilization, small size, light weight and low cost. It will have a certain prospect of application in the airborne telemetry transmitting sets.

The Common Airborne Instrumentation System Program Management OverviewBrown, Thomas R., Jr. 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Department of Defense, through a Tri-Service Program Office, is developing the Common Airborne Instrumentation System (CAIS) to promote standardization, commonality, and interoperability among aircraft test instrumentation systems. The advent of CAIS will change how the DoD test community conducts business. The CAIS program will allow aircraft test and evaluation facilities to utilize common airborne systems, ground support equipment, and technical knowledge for airborne instrumentation systems. The CAIS Program Office will conduct requirements analyses, manage system upgrades, and provide full life cycle support for this system. It is initiating several requirements contracts to provide direct ordering opportunities for DoD users to easily procure defined test instrumentation hardware. The program office will provide configuration management, inventory control, maintenance support, system integration, engineering support, and software management. In addition, it will continue to enhance the current system and develop new items to meet future requirements. Where existing equipment provides added benefit, this equipment may be added to the official CAIS family.

Airborne Gravity Gradient, Magnetic and VLF datasets : Case studies of modelling, inversion and interpretationAbtahi, Sayyed Mohammad January 2016 (has links)
Northern Sweden is one of the largest hosts for mineral resources in Europe and always has been an interesting area for researchers from various disciplines of Earth sciences. This dissertation is a comprehensive summary of three case study papers on airborne VLF, gravity gradient and magnetic data in the area. In the first paper, tensor VLF data is extracted from an old data set which contains only the total and the vertical magnetic components. The anomalous part of the horizontal magnetic field components is computed by a Hilbert transform of the vertical magnetic field. The normal part of the horizontal magnetic field component is computed as a function of total, vertical and anomalous part of horizontal magnetic fields. The electric field is also calculated for TE mode and impedance tensor and apparent resistivity are computed. In addition tippers are calculated for two transmitters and inverted by a 3D inversion algorithm. Comparison of the estimated model and geology map of bedrock shows that lower resistivity zones are correlated with mineralizations. The second paper deals with the internal consistency of airborne gravity gradient data. The six components of the data are estimated from a common potential function. It is shown that the data is adequately consistent but at shorter land clearances the difference between the estimated data and the original data is larger. The technique is also used for computing the Bouguer anomaly from terrain corrected FTG data. Finally the data is inverted in 3D, which shows that the estimated density model in shallow depth is dominated by short wave length features. Inversion of TMI data is the topic of the third paper where a new type of reference model for 3D inversion of magnetic data is proposed by vertically extending the estimated magnetization of a 2D terrain magnetization model. The final estimated 3D result is compared with the magnetization model where no reference model is used. The comparison shows that using the reference model helps the high magnetization zones in the estimated model at shallow depths to be better correlated with measured high remanent magnetization from rock samples. The high magnetization zones are also correlated with gabbros and volcanic metasediments.

A Qualitative Survey of the Airborne Algae, Protozoa, and Bacteria at the Denton Sewage Treatment PlantMahoney, Joseph L. 05 1900 (has links)
This study had a three-fold purpose. First, it was decided to determine if algae and protozoa were emitted to the air at the Denton sewage treatment plant. The information obtained could be of future importance in the fields of algal and protozoan ecology and public health. Second, it was decided to make a survey of the airborne bacteria at this plant. Some researchers have described bacterial air contamination at similar sewage treatment plants, but the one in Denton has not been studied. Third, it was hoped that in this research some relationships could be found between the bacteria and the algae and protozoa in the air in the vicinity of the sewage aeration basin. It was hypothesized that pathogenic bacteria were carried in the air with these other organisms.

Epidemiology of Airborne Virulent Rhodococcus equi at Horse Breeding FarmsKuskie, Kyle Ryan 2011 December 1900 (has links)
Rhodococcus equi causes severe pneumonia, resulting in disease and sometimes death of foals. Infection is thought to occur by inhalation of dust contaminated with virulent R equi. A recent study of 3 horse breeding farms in Ireland found airborne concentrations of virulent R equi to be significantly higher in stables than in paddocks. More importantly, another study from Australia established an association of airborne concentrations of virulent R equi with the prevalence of R equi pneumonia at 28 farms. The extent to which these associations extend to other farms in different parts of the world is not known.
Two farms in central Kentucky with recurrent R equi pneumonia in foals were studied from February through July 2008. Air samples were collected and environmental factors were measured hourly for a 24-hour period each month from stalls and paddocks used to house mares and their foals at each farm. In 2009, samples were collected from 47 foals from stalls at a single horse-breeding farm in central Kentucky on days 1-2, days 7-9, and days 14-16 of life. Concentrations of airborne virulent R equi were determined via a modified colony immunoblot technique.
Airborne concentrations of virulent R equi were significantly higher (P = 0.016) from 6:00 A.M. through 11:59 P.M. than for the period from midnight through 5:59 A.M. Presence of the mare and foal at the time of sampling was significantly (P < 0.001) associated with increased airborne concentrations of virulent R equi in stalls. The presence of virulent R equi in stalls was significantly (P = 0.045) more likely at 7 days of age for foals subsequently found to be affected by rhodococcal pneumonia.
These findings suggest that recovery of airborne virulent R equi is less likely between 12:00 A.M. and 5:59 A.M., relative to other times, that airborne concentrations of virulent R equi are significantly increased when horses are present at the site for collection of air samples, and that environments containing airborne virulent R equi during the first week of life may influence the risk of subsequent disease for a foal.

''A far more formidable task'': the 101st Airborne Division's pacification of Thua Thien Province, Republic of Vietnam, 1968-1972Werkheiser, Edwin Brooks, II 30 October 2006 (has links)
This thesis seeks to identify, describe, and analyze the tactics used by the 101st
Airborne Division in the pacification of the Republic of Vietnam's Thua Thien province
from 1968 to 1972. Despite the larger calamity of the Vietnam War, the 101st developed
an effective set of measures against the Vietnamese communist insurgency. These
measures depended largely on the ability of the division's lower-level units to attack the
Viet Cong political infrastructure, provide security for Thua Thien's population, and
build effective South Vietnamese territorial forces in their areas of operation following
the communist 1968 Tet offensive.
These findings are based on the official reports, orders, and records generated by
the division during its service in Vietnam and currently stored in the National Archives
in College Park, Maryland and U.S. Army's Military History Institute in Carlisle
Barracks, Pennsylvania. Additionally, the Military History Institute's "Company Command in Vietnam" series of interviews conducted from 1982 to 1984 with officers
who served in Vietnam provided valuable insight. This thesis looks at
counterinsurgency practices at the lowest levels where theory and policy are translated
into action. Operations Narrative: 3 September 1970. "At 0525 hours D Company, 3d
Platoon had two frag grenades tossed into its night defensive position. A member of the
platoon threw one of the grenades out of the position before it exploded. He jumped on
the other grenade and covered it with his body. The grenade did not explode due to the
fact that the safety had not been removed."1
I was inspired to undertake and complete this study by the courageous and
fortunate soldier in 3rd Platoon, D Company, 3-187th Infantry and the thousands of others
like him whose exploits I found in the footnotes of the Vietnam War. Their stories were
resting uneasily as antiseptic fragments in a hundred reports, giving single-sentence
snapshots of their part in a war many more clever people declared lost just as they began
their fight in 1968. Their names are forgotten to time and their efforts largely relegated
to obscurity by others who occupied a larger, grenade-free stage at much less personal
risk. Still, they are the men we all want alongside us in our night defensive position.
Their deeds are much easier to comment on than they were to perform.

Experiences of studying airborne wear particles from road and rail transportAbbasi, Saeed, Sellgren, Ulf, Olofsson, Ulf Unknown Date (has links)
Airborne particles and their adverse effects on air quality have been recognized by humans since ancient times. Current exhaust emission legislations increase the relative contribution of wear particles on the PM levels. Consequently, wear-based particle emissions from rail and road transport have raised concerns as ground transportation is developing quickly. Although scientific research on airborne wear-based particles started in 1909, there is almost no legislation that control the generation of wear-based particles. In addition, there is no accepted and approved standard measurement technique for monitoring and recording particle characteristics. The main objective of this study is to review recent experimental work in this field and to discuss their set-ups, the sampling methods, the results, and their limitations, and to propose measures for reducing these limitations.
