“…Similar to LiDAR though, SAR has high weight and power requirements (Tsunoda et al, 2000;Gonzalez Bonilla et al, 2009;Muoz et al, 2009). However, smaller SAR systems are becoming commercially available (Edrich,2004;ZauggandLong,2008),withmuchlowerweightandpower requirements and with resolutions of 20 to 50 cm.…”

Aerial terrain mapping has been used for many years to monitor natural habitats and ecosystems, assist in urban planning, and monitor trends in land usage. Recent improvements in digital imaging, LiDAR, and synthetic aperture radar have facilitated the generation of 3-D terrain models for analysis in these applications. Unfortunately,thesesystemstypicallyrequirelargemannedaircraftandsignificant post-processing of data before viewable results are produced. This inhibits use of these technologies in time-critical applications such as disaster relief, autonomous obstacle avoidance, and landing-zone assessment for a vertical take-off and landing aircraft. This paper describes a wide-baseline stereo vision system that enables near-real-time generation of dense 3-D terrain maps. The key advantage of computational stereo vision over monocular structure-from-motion is that terrain can be reconstructed from a single synchronized pair of calibrated images. The paper describes a working prototype, and presents a novel approach for combining separate stereo maps into larger terrain mosaics. The new stereo system and algorithm have an accuracy rangingfrom56cmto65cmacrossthefieldofviewatanaltitudeof40m.Also, dense correlation of the imagery generates over 2200 points/m 2 . The system weighs just 3.1 kg, roughly one-fourth the weight of comparable high-altitude mapping systems, at ca. one-tenth the cost. The paper also describes potential implementations usingField-ProgrammableGateArrays(FPGAs)andApplication-SpecificIntegrated Circuits (ASICs) for real-time operation.

“…Munoz-Bonilla and Fernández-García provided in 2012 a systematic review on the different synthetic polymers with antibacterial properties, including design, synthesis and antimicrobial testing. 21 More detailed discussions of the mechanism of action of antibacterial polymers were provided by Timofeeva and Kleshcheva, and Siedenbiedel and Tiller. Timofeeva and Kleshcheva summarized the mechanisms of action of antibacterial polymers and their coatings, and the factors that influence the behavior and toxicity of the materials, including molecular weight, alkylation and structure of the amine groups.…”

Biocidal Polymers: A Mechanistic Overview

et al. 2016

Bacterial fouling on surfaces is considered a major problem in modern society. Conventional methods to prevent biofilm formation often have little effect and may induce further contamination. In response to this challenge, antibacterial polymers have been designed and applied as an alternative approach to kill or inhibit bacteria and prevent the formation of biofilm. These polymers can be grouped into three broad classes, namely antibiotic-releasing polymers, polymeric antibiotics and antibiotic polymers. Antibiotic polymers are effective against bacteria both in solution and as coatings, through different mechanisms of action. In order to enhance their efficacy, antibacterial polymers have been designed with single or combined antibacterial and antibiofouling actions. The current review summarizes the mechanisms of action of antibacterial polymers, especially antibiotic polymers, both in solution and as coatings. It also discusses the antibacterial polymers with multiple functionalities.
