Data set - Monitoring light pollution with an unmanned aerial vehicle
<p>Dataset used in the study Monitoring light pollution with an unmanned aerial vehicle. A digital camera and a sky quality meter mounted on a UAV have been used to study the relationship between indices computed on night images and night ground brightness (NGB) measured by an optical device pointed downward towards the ground. Both measurements were taken contemporarily during flights at 70 meter and 100 meters altitude, and also varying exposure time.</p>

Resveratrol loaded chitosan-pectin core-shell nanoparticles as novel drug delivery vehicle for sustained release and improved antioxidant activities
<p><span>Resveratrol, chemically known as 3, 5, 4'-trihydroxy-trans-stilbene, is a natural polyphenol with promising multi-targeted health benefits. The optimal therapeutic uses of resveratrol are limited due to its poor solubility, rapid metabolism and low bioavailability. To address the issues, we have encapsulated resveratrol inside the nanosized core made of chitosan and coated this core with pectin - shell in order to fabricate a drug delivery vehicle which can entrap resveratrol for a longer period of time. The core - shell nanoparticles fabricated in this way were characterized with the help of Fourier Transform Infrared Spectrometer (FTIR), Field Emission Scanning Electron Microscope (FESEM), Field Emission Transmission electron microscopy/Selected Area Electron Diffraction (FETEM/SAED), High-Resolution Transmission Electron Microscope (HRTEM)), Dynamic Light Scattering (DLS) and Zeta Potential measurements. In vitro drug release study showed the ability of the core-shell nanoparticles to provide sustained release of resveratrol for almost 30 hours. The release efficiency of the drug was found to be pH dependent and a sequential control over drug release can be obtained varying the shell thickness. The resveratrol encapsulated in a nanocarrier was found to have a better in vitro antioxidant activity than free resveratrol as determined by DPPH radical scavenging method. This work finally offers a novel nano-based drug delivery system.</span></p>
Unmanned aerial vehicles as a useful tool for investigating animal movements - samples
<p><span>Determining animal abundance is crucial for assessing the effectiveness of management measures against pest animals. Meanwhile, investigating animal movements has become important for conducting abundance estimations of unmarked animals since the random encounter model (REM)</span><span> was published. REM is a camera-trapping method </span><span>that derives animal density by using contact ratio between camera-traps and targeted animals that randomly move at a certain speed in a given area. However, it</span><span> requires an independent value, which is animal speed. F</span><span>or investigating animal speed, camera-traps with video recording and GPS tagging are the commonly used tools.</span></p> <p><span>U</span><span>nmanned aerial vehicles (UAVs) are currently used in wildlife monitoring to investigate the abundance of target species. It is evaluated as a tool that is non-invasive and suitable for surveys in inaccessible landscapes. Considering these characteristics, we regarded a distant survey using this technology as suitable for investigating animal movements. </span><span>Therefore, we proposed a method for estimating animal movements using UAVs and conducted a case study that aimed to investigate wild boars' movements.</span></p> <p><span>We collected 11 video samples that successfully followed the movements of wild boars from 26 UAV flights in total, and the average speed of their movements derived from all the samples was 1.54 km/24 h.</span></p> <p><span>We found that issues can be improved, including species identification, video sample length, and animal behaviours or activity patterns. On the other hand, our method showed potential for applying to species with specific characteristics in their body size, shape or activity patterns. With improvements in the issues mentioned above, UAVs would become an alternative tool for investigating animal movements.</span></p>

Wildlife-vehicle collisions at 42 Florida State Parks, 2005-2015
<p class="western"><span>Peninsular Florida, USA: 9,254 WVC survey records collected by Florida State Parks personnel at 42 parks during a decade (2005-2015). Data represent observations of wildlife-vehicle collisions for birds (138 species), mammals (35 species), and reptiles (64 species). The 42 state parks encompassed a variety of Florida's ecosystems on the peninsula and keys (and North, but not the Florida panhandle) from barrier islands and the Everglades to pine flatwoods, sandhills, and urban areas. Climate ranged from subtropical in South Florida to warm temperate in North Florida. </span></p>

XM800 Armored Scout Vehicle (3D Scan)
I've been on vacation the past week, I went to a lot of museums, but this is the only 3D scan that came out looking decent. The florida sun isn't exactly good for photogrammetry. This particular scan is of a cancelled prototype armored scout car, scanned at the Fort Walton Beach Armament Museum.

Asymmetric Collaborative Bar Stabilization Tethered to Two Heterogeneous Aerial Vehicles
<p>We consider a system composed of a bar tethered to two unmanned aerial vehicles (UAVs), where the cables behave as rigid links under tensile forces, and with the control objective of stabilizing the bar's pose around a desired pose. Each UAV is equipped with a PID control law, and we verify that the bar's motion is decomposable into three decoupled motions, namely a longitudinal, a lateral and a vertical. We then provide relations between the UAVs' gains, which, if satisfied, allows us to decompose each of those motions into two cascaded motions; the latter relations between the UAVs' gains are found so as to counteract the system asymmetries, such as the different cable lengths and the different UAVs' weights. Finally, we provide conditions, based on the system's physical parameters, that describe good and bad types of asymmetries. We present experiments that demonstrate the stabilization of the bar's pose.</p>
Quantitative evidence for modelling electric vehicles - Supplementary Data
<p><strong>Please cite as:</strong></p> <p>Malte Jansen, Rob Gross, and Iain Staffell. ‘Quantitative Evidence for Modelling Electric Vehicles’. <em>Renewable and Sustainable Energy Reviews</em> 199 (1 July 2024): 114524. <a href="https://doi.org/10.1016/j.rser.2024.114524">https://doi.org/10.1016/j.rser.2024.114524</a>.</p> <p><strong>Abstract:</strong></p> <p>Electric vehicles are now a major contributor to decarbonising the transport sector. Their rollout has accelerated rapidly since 2020, reaching a global fleet of 40 million in 2023. This presents both problems and opportunities for electricity systems, with charging increasing peak loads, but also providing a large new source of flexibility to help manage increased shares of wind and solar generation, shift peak demand and improve network management.</p> <p>While EV flexibility is widely discussed, there is uncertainty surrounding the magnitude to which EVs could help electricity systems, and a distinct lack of quantitative evidence around adoption, charging behaviour and technical capabilities for load shifting. This study employs the rapid evidence assessment method to synthesise recent information. We find that studies expect that EVs could provide 1–11 GW of flexible capacity per million vehicles (median: 3.7 GW), with the ability to shift demand by 1.5–5 hours (median: 4 hours) and a price elasticity of –0.77 to –0.10 (median: –0.15). Diurnal profiles of charging demand and availability for providing flexibility are aggregated across multiple studies. The results are relevant for energy modellers and show that the interaction between EVs and electricity systems can be generalised on a widely-applicable basis.</p>
