“…Previous research has demonstrated that there are a number of clear benefits associated with increased frame rates, including: the visibility of temporal aliasing artefacts being diminished [10,[21][22][23][24][25][26]; a reduction in perceptible motion blur [23][24][25][27][28][29]; increased realism, smoother motion, improved depth perception for both expert [30] and non-expert [31] viewers (especially when tracking using smooth pursuit eye movements); more realistic motion image quality (confirmed using EEG data) [32]; a reduction in viewer stress levels [33] (signified by a lower blinking frequency [34]); an improvement in speed and spatial discrimination, and reading ability [35]; and an increase in perceptual quality [18,36], at least up to 240 fps [29]. The use of higher frame rates also enhances the ability to capture and playback slow-motion videos [37].…”

“…Myotid bats, and other low duty cycle bats, prevent selfdeafening by desensitizing their ears as they emit their very loud echolocation pulses [28]. The wing morphology [6], body size [6] and the general occurrence of M. tricolor over water bodies [11] suggests that this species may be a generalist that utilises more than one foraging strategy; i.e. trawling or gleaning and aerial hawking.…”

We used three complementary methods to assess the diet of two insectivorous bat species: one an obligate aerial hunter, Miniopterus natalensis, and the other Myotis tricolor whose morphology and taxonomic affiliation to other trawling bats suggests it may be a trawler (capturing insects from the water surface with its feet and tail). We used visual inspection, stable isotope values and fatty acid profiles of insect fragments in bat faeces sampled across five sites to determine the contribution of aquatic and terrestrial arthropods to the diets of the two species. The niche widths of M. tricolor were generally wider than those of Miniopterus natalensis but with much overlap, both taking aquatic and terrestrial insects, albeit in different proportions. The diet of M. tricolor had high proportions of fatty acids (20:5ω3 and 22:6ω3) that are only obtainable from aquatic insects. Furthermore, the diet of M. tricolor had higher proportions of water striders (Gerridae) and whirligig beetles (Gyrinidae), insects obtainable via trawling, than Miniopterus natalensis. These results suggest both species are flexible in their consumption of prey but that M. tricolor may use both aerial hawking and trawling, or at least gleaning, to take insects from water surfaces. The resultant spatial segregation may sufficiently differentiate the niches of the two species, allowing them to co-exist. Furthermore, our results emphasize that using a combination of methods to analyse diets of cryptic animals yields greater insights into animal foraging ecology than any of them on their own.

“…The low acquisition time is caused by the limited internal memory storage and the high recording frame rate of commercial cameras. Subsequent data transfer from the internal camera memory to the external computer is performed at a much lower speed [8]. By removing on-camera memory buffers on our smart camera, the duration of the acquisition is prolonged and limited only by the size of the main memory (RAM) of the recording computer.…”

High-speed X-ray imaging applications play a crucial role for non-destructive investigations of the dynamics in material science and biology. On-line data analysis is necessary for quality assurance and data-driven feedback, leading to a more efficent use of a beam time and increased data quality. In this article we present a smart camera platform with embedded Field Programmable Gate Array (FPGA) processing that is able to stream and process data continuously in real-time. The setup consists of a Complementary Metal-Oxide-Semiconductor (CMOS) sensor, an FPGA readout card, and a readout computer. It is seamlessly integrated in a new custom experiment control system called Concert that provides a more efficient way of operating a beamline by integrating device control, experiment process control, and data analysis. The potential of the embedded processing is demonstrated by implementing an image-based trigger. It records the temporal evolution of physical events with increased speed while maintaining the full field of view. The complete data acquisition system, with Concert and the smart camera platform was successfully integrated and used for fast X-ray imaging experiments at KIT's synchrotron radiation facility ANKA.Index Terms-CMOS image sensors, control systems, data processing, FPGAs, smart cameras. 0018-9499
