Since the “invention” of free flight, an outstanding question is how much traffic demand can safely be accommodated by airborne self separation. In order to answer this question, within the iFly project an advanced airborne self separation concept of operations (ConOps) has been developed. This paper shows the results of an assessment of this ConOps on safety risk under very high en-route traff...

In general, airborne photogrammetry and LiDAR measurements are applied to geometrical data acquisition for automated map generation and revision. However, attribute data acquisition and classification depend on manual editing works including ground surveys. On the other hand, SAR data have a possibility to automate the attribute data acquisition and classification. Thus, we focus on an integrat...

The generation of airborne microorganisms from concentrated animal-feeding operations (CAFOs) is a concern from a human and animal health perspective. To better understand the airborne microorganisms found in these environments, a number of collection and analytical techniques have been utilized and will be discussed in this review. The most commonly used bioaerosol collection method is the liq...

The primary objective of the study is to determine the reduction of airborne microbial counts as a result of operating the AiroCide system in three clinical settings under control conditions. The three settings are Ear, Nose & Throat (ENT) Day Surgery, Surgical Operating Room (OR) and Surgical Instrument Sterile Preparation Room. 2) The second objective is to determine how/if the AiroCide syste...

The US National Science Foundation supports and utilizes a range of platforms which are made available to its US funded science investigators in the furtherance of airborne science program objectives. As well as providing access to the platforms themselves, NSF also supports their operation, maintenance and infrastructure development. NSF airborne science projects may be deployed worldwide. Whi...

A near real time airborne monitoring system for monitoring of natural disasters, mass events, and large traffic disasters was developed in the last years at the German Aerospace Center (DLR). This system consists of an optical wide-angle camera system (3K system), a SAR sensor, an optical and microwave data downlink, an onboard processing unit and ground processing station with online data tran...

The American Conference of Governmental Industrial Hygienists (ACGIH) increased the threshold level Values (TLVs) for airborne ultrasound and these levels were adopted by Occupational Safety and Health Administration (OSHA) in 2003. The European community, Australia and Canada have retained the more stringent levels that stemmed from reports of “ultrasonic sickness” in the 1960s. Ultrasound can...

By the use of a modified ionizer device we describe effective prevention of airborne transmitted influenza A (strain Panama 99) virus infection between animals and inactivation of virus (>97%). Active ionizer prevented 100% (4/4) of guinea pigs from infection. Moreover, the device effectively captured airborne transmitted calicivirus, rotavirus and influenza virus, with recovery rates up to 21%...

Abstract. This paper mainly describes the rectification method of digital airborne image distortion. First, according to the digital sensor model, the mathematical model of airborne image is built up for processing the geometrical data of image, which is also the key for digital rectification. Then, the principle of digital rectification is explained through discussing the direct method and the...

Environmental conditions and airborne myco£lora were measured concurrently in 10 turkey confinement houses during warm and cold weather. The following variables in the environment were measured: numbers of feedand litter-associated yeast and mold fungi, temperature, relative humidity, airspeed, carbon dioxide and ammonia concentration, airborne bacteria, and airborne particulate mass, particle ...
