and 3D area mapping using high-resolution photogrammetric methods from multispectral imaging, also taking advantage of the 3D scanning techniques from the SCAN4RECO project. We also present a proprietary embedded sensor system used for the detection of fire ignitions in the forest using near-infrared based scanner with weight and form factors allowing it to be easily deployed on standard commercial micro-UAVs, such as DJI Inspire or Mavic. Results from real-life pilot trials in Greece, Spain, and Israel demonstrated added-value in the use of UAS for precise and reliable detection of forest fires, as well as high-resolution 3D aerial modeling for accurate quantification of human resources and equipment required for firefighting.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Forest%20wildfires" title="Forest wildfires">Forest wildfires</a>, <a href="https://publications.waset.org/search?q=fuel%20volume%20estimation" title=" fuel volume estimation"> fuel volume estimation</a>, <a href="https://publications.waset.org/search?q=3D%20modeling" title=" 3D modeling"> 3D modeling</a>, <a href="https://publications.waset.org/search?q=UAV" title=" UAV"> UAV</a>, <a href="https://publications.waset.org/search?q=surveillance" title=" surveillance"> surveillance</a>, <a href="https://publications.waset.org/search?q=firefighting" title=" firefighting"> firefighting</a>, <a href="https://publications.waset.org/search?q=ignition%20detectors." title=" ignition detectors."> ignition detectors.</a> </p> <a href="https://publications.waset.org/10011614/application-of-uas-in-forest-firefighting-for-detecting-ignitions-and-3d-fuel-volume-estimation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10011614/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10011614/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10011614/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10011614/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10011614/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10011614/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10011614/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10011614/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10011614/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10011614/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10011614.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">582</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Protection of Cultural Heritage against the Effects of Climate Change Using Autonomous Aerial Systems Combined with Automated Decision Support</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Artur%20Krukowski">Artur Krukowski</a>, <a href="https://publications.waset.org/search?q=Emmanouela%20Vogiatzaki"> Emmanouela Vogiatzaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The article presents an ongoing work in research projects such as SCAN4RECO or ARCH, both funded by the European Commission under Horizon 2020 program. The former one concerns multimodal and multispectral scanning of Cultural Heritage assets for their digitization and conservation via spatiotemporal reconstruction and 3D printing, while the latter one aims to better preserve areas of cultural heritage from hazards and risks. It co-creates tools that would help pilot cities to save cultural heritage from the effects of climate change. It develops a disaster risk management framework for assessing and improving the resilience of historic areas to climate change and natural hazards. Tools and methodologies are designed for local authorities and practitioners, urban population, as well as national and international expert communities, aiding authorities in knowledge-aware decision making. In this article we focus on 3D modelling of object geometry using primarily photogrammetric methods to achieve very high model accuracy using consumer types of devices, attractive both to professions and hobbyists alike.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=3D%20modeling" title="3D modeling">3D modeling</a>, <a href="https://publications.waset.org/search?q=UAS" title=" UAS"> UAS</a>, <a href="https://publications.waset.org/search?q=cultural%20heritage" title=" cultural heritage"> cultural heritage</a>, <a href="https://publications.waset.org/search?q=preservation." title=" preservation."> preservation.</a> </p> <a href="https://publications.waset.org/10011727/protection-of-cultural-heritage-against-the-effects-of-climate-change-using-autonomous-aerial-systems-combined-with-automated-decision-support" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10011727/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10011727/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10011727/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10011727/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10011727/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10011727/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10011727/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10011727/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10011727/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10011727/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10011727.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">705</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Comparison between Approaches Used in Two WalkAbout Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Derek%20O%20Reilly">Derek O Reilly</a>, <a href="https://publications.waset.org/search?q=Piotr%20Milczarski"> Piotr Milczarski</a>, <a href="https://publications.waset.org/search?q=Shane%20Dowdall"> Shane Dowdall</a>, <a href="https://publications.waset.org/search?q=Artur%20H%C5%82oba%C5%BC"> Artur Hłobaż</a>, <a href="https://publications.waset.org/search?q=Krzysztof%20Podlaski"> Krzysztof Podlaski</a>, <a href="https://publications.waset.org/search?q=Hiram%20Bollaert"> Hiram Bollaert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Learning through creation of contextual games is a very promising approach when undertaking interdisciplinary and international group projects.

Characteristic behavior of decision trees (DTs) and rough sets theory (RST) in rules extraction from recorded data is discussed and illustrated with simple examples. The significance of the models- drawbacks was evaluated, using simulated and industrial data sets. It is concluded that performance of DTs may be considerably poorer in several important aspects, compared to RST, particularly when not only a characterization of a problem is required, but also detailed and precise rules are needed, according to actual, specific problems to be solved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Knowledge%20extraction" title="Knowledge extraction">Knowledge extraction</a>, <a href="https://publications.waset.org/search?q=decision%20trees" title=" decision trees"> decision trees</a>, <a href="https://publications.waset.org/search?q=rough%20setstheory" title=" rough setstheory"> rough setstheory</a>, <a href="https://publications.waset.org/search?q=industrial%20processes." title=" industrial processes."> industrial processes.</a> </p> <a href="https://publications.waset.org/7119/comparative-study-of-decision-trees-and-rough-sets-theory-as-knowledge-extractiontools-for-design-and-control-of-industrial-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7119/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7119/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7119/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7119/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7119/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7119/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7119/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7119/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7119/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7119/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7119.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1633</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> A Novel Metric for Performance Evaluation of Image Fusion Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Nedeljko%20Cvejic">Nedeljko Cvejic</a>, <a href="https://publications.waset.org/search?q=Artur%20%C5%81oza"> Artur Łoza</a>, <a href="https://publications.waset.org/search?q=David%20Bull"> David Bull</a>, <a href="https://publications.waset.org/search?q=Nishan%20Canagarajah"> Nishan Canagarajah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we present a novel objective nonreference performance assessment algorithm for image fusion.

Experimental results confirm that the values of the proposed metrics correlate well with the subjective quality of the fused images, giving a significant improvement over standard measures based on mean squared error and mutual information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fusion%20performance%20measures" title="Fusion performance measures">Fusion performance measures</a>, <a href="https://publications.waset.org/search?q=image%20fusion" title=" image fusion"> image fusion</a>, <a href="https://publications.waset.org/search?q=nonreferencequality%20measures" title=" nonreferencequality measures"> nonreferencequality measures</a>, <a href="https://publications.waset.org/search?q=objective%20quality%20measures." title=" objective quality measures."> objective quality measures.</a> </p> <a href="https://publications.waset.org/1046/a-similarity-metric-for-assessment-of-image-fusion-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/1046/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/1046/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/1046/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/1046/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/1046/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/1046/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/1046/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/1046/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/1046/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/1046/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/1046.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2492</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Communicative and Artistic Machines: A Survey of Models and Experiments on Artificial Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Artur%20Matuck">Artur Matuck</a>, <a href="https://publications.waset.org/search?q=Guilherme%20F.%20Nobre"> Guilherme F.

The viscous and heat relaxation loss in the stack determines the critical temperature gradient. In this work, a dimensionless critical temperature gradient factor is obtained based on the linear thermoacoustic theory. It is indicated that the impedance determines the proportion between the viscous loss, heat relaxation losses and the power production from the heat energy. It reveals the effects of the channel dimensions, geometrical configuration and the local acoustic impedance on the critical temperature gradient in stacks. The numerical analysis shows that there exists a possible optimum combination of these parameters which leads to the lowest critical temperature gradient. Furthermore, several different geometries have been tested and compared numerically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Critical%20temperature%20gradient" title="Critical temperature gradient">Critical temperature gradient</a>, <a href="https://publications.waset.org/search?q=heat%20relaxation" title=" heat relaxation"> heat relaxation</a>, <a href="https://publications.waset.org/search?q=stack" title=" stack"> stack</a>, <a href="https://publications.waset.org/search?q=viscous%20effect." title=" viscous effect."> viscous effect.</a> </p> <a href="https://publications.waset.org/11881/impact-of-viscous-and-heat-relaxation-loss-on-the-critical-temperature-gradients-of-thermoacoustic-stacks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11881/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11881/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11881/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11881/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11881/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11881/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11881/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11881/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11881/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11881/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11881.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1806</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Ecotoxicological Safety of Wastewater Treated with Lignocellulosic Adsorbents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Lu%C3%ADsa%20P.%20Cruz-Lopes">Luísa P.

The temperature gradient along the regenerator caused by the two heat exchangers excites and maintains the acoustic wave in the resonator. The devices are called travelling wave thermoacoustic systems because the phase angle difference between the pressure and velocity oscillation is close to zero in the regenerator. This paper presents the construction and testing of a thermoacoustic engine equipped with a ceramic regenerator, made from a ceramic material that is usually used as catalyst substrate in vehicles- exhaust systems, with fine square channels (900 cells per square inch). The testing includes the onset temperature difference (minimum temperature difference required to start the acoustic oscillation in an engine), the acoustic power output, thermal efficiency and the temperature profile along the regenerator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Regenerator" title="Regenerator">Regenerator</a>, <a href="https://publications.waset.org/search?q=Temperature%20gradient" title=" Temperature gradient"> Temperature gradient</a>, <a href="https://publications.waset.org/search?q=Thermoacoustic" title=" Thermoacoustic"> Thermoacoustic</a>, <a href="https://publications.waset.org/search?q=Travelling-wave." title=" Travelling-wave."> Travelling-wave.</a> </p> <a href="https://publications.waset.org/6539/construction-and-performance-characterization-of-the-looped-tube-travelling-wave-thermoacoustic-engine-with-ceramic-regenerator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6539/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6539/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6539/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6539/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6539/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6539/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6539/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6539/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6539/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6539/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6539.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2266</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Vortex Shedding at the End of Parallel-plate Thermoacoustic Stack in the Oscillatory Flow Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Lei%20Shi">Lei Shi</a>, <a href="https://publications.waset.org/search?q=Zhibin%20Yu"> Zhibin Yu</a>, <a href="https://publications.waset.org/search?q=Artur%20J.%20Jaworski"> Artur J.

Here, Particle Image Velocimetry (PIV) is used to quantify the vortex shedding processes within an acoustic cycle phase-by-phase, in particular during the “ejection" of the fluid out of the stack. Standard hot-wire anemometry measurement is also applied to detect the velocity fluctuations near the end of the stack. Combination of these two measurement techniques allowed a detailed analysis of the vortex shedding phenomena. The results obtained show that, as the Reynolds number varies (by varying the plate thickness and drive ratio), different flow patterns of vortex shedding are observed by the PIV measurement. On the other hand, the time-dependent hot-wire measurements allow obtaining detailed frequency spectra of the velocity signal, used for calculating characteristic Strouhal numbers. The impact of the plate thickness and the Reynolds number on the vortex shedding pattern has been discussed. Furthermore, a detailed map of the relationship between the Strouhal number and Reynolds number has been obtained and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Oscillatory%20flow" title="Oscillatory flow">Oscillatory flow</a>, <a href="https://publications.waset.org/search?q=Parallel-plate%20thermoacoustic%20stack" title=" Parallel-plate thermoacoustic stack"> Parallel-plate thermoacoustic stack</a>, <a href="https://publications.waset.org/search?q=Strouhal%20numbers" title=" Strouhal numbers"> Strouhal numbers</a>, <a href="https://publications.waset.org/search?q=Vortex%20shedding." title=" Vortex shedding."> Vortex shedding.</a> </p> <a href="https://publications.waset.org/10616/vortex-shedding-at-the-end-of-parallel-plate-thermoacoustic-stack-in-the-oscillatory-flow-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10616/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10616/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10616/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10616/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10616/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10616/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10616/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10616/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10616/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10616/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10616.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1884</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Multimedia Firearms Training System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Aleksander%20Nawrat">Aleksander Nawrat</a>, <a href="https://publications.waset.org/search?q=Karol%20J%C4%99drasiak"> Karol Jędrasiak</a>, <a href="https://publications.waset.org/search?q=Artur%20Ryt"> Artur Ryt</a>, <a href="https://publications.waset.org/search?q=Dawid%20Sobel"> Dawid Sobel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The goal of the article is to present a novel Multimedia Firearms Training System. The system was developed in order to compensate for major problems of existing shooting training systems. The designed and implemented solution can be characterized by five major advantages: algorithm for automatic geometric calibration, algorithm of photometric recalibration, firearms hit point detection using thermal imaging camera, IR laser spot tracking algorithm for after action review analysis, and implementation of ballistics equations. The combination of the abovementioned advantages in a single multimedia firearms training system creates a comprehensive solution for detecting and tracking of the target point usable for shooting training systems and improving intervention tactics of uniformed services. The introduced algorithms of geometric and photometric recalibration allow the use of economically viable commercially available projectors for systems that require long and intensive use without most of the negative impacts on color mapping of existing multi-projector multimedia shooting range systems. The article presents the results of the developed algorithms and their application in real training systems.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Firearms%20shot%20detection" title="Firearms shot detection">Firearms shot detection</a>, <a href="https://publications.waset.org/search?q=geometric%20recalibration" title=" geometric recalibration"> geometric recalibration</a>, <a href="https://publications.waset.org/search?q=photometric%20recalibration" title=" photometric recalibration"> photometric recalibration</a>, <a href="https://publications.waset.org/search?q=IR%20tracking%20algorithm" title=" IR tracking algorithm"> IR tracking algorithm</a>, <a href="https://publications.waset.org/search?q=thermography" title=" thermography"> thermography</a>, <a href="https://publications.waset.org/search?q=ballistics." title=" ballistics.

However, with the ‘conventionalization’ of these products, it has been questioned whether these products have been losing their original vision. Accordingly, this research based on 31 phenomenological interviews with committed organic consumers in urban and rural areas of Portugal, aims to analyse how ethical motivations and ecological awareness are related to organic food consumption. The content thematic analysis highlights aspects related to society and environmental concerns. On an individual level, the importance of internal coherence, peace of mind and balance that these consumers find in the consumption of local organic products was stressed. For these consumers, local organic products consumption made for significant changes in their lives, aiding in the establishment of a green identity, and involves a certain philosophy of life. This vision of an organic lifestyle is grounded in a political and ecological perspective, beyond the usual organic definition, as a ‘post-organic era’. The paper contributes to better understand how an ideological environmental discourse allows highlighting the relationship between consumers’ environmental concerns and the politics of food, resulting in a possible transition to new sustainable consumption practices.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Organic%20consumption" title="Organic consumption">Organic consumption</a>, <a href="https://publications.waset.org/search?q=localism" title=" localism"> localism</a>, <a href="https://publications.waset.org/search?q=content%20thematic%20analysis" title=" content thematic analysis"> content thematic analysis</a>, <a href="https://publications.waset.org/search?q=pro-environmental%20discourse" title=" pro-environmental discourse"> pro-environmental discourse</a>, <a href="https://publications.waset.org/search?q=political%20consumption" title=" political consumption"> political consumption</a>, <a href="https://publications.waset.org/search?q=Portugal." title=" Portugal."> Portugal.</a> </p> <a href="https://publications.waset.org/10008649/choosing-local-organic-food-consumer-motivations-and-ethical-spaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10008649/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10008649/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10008649/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10008649/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10008649/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10008649/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10008649/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10008649/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10008649/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10008649/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10008649.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1447</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Valorization of Lignocellulosic Wastes – Evaluation of Its Toxicity When Used in Adsorption Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Isabel%20Br%C3%A1s">Isabel Brás</a>, <a href="https://publications.waset.org/search?q=Artur%20Figueirinha"> Artur Figueirinha</a>, <a href="https://publications.waset.org/search?q=Bruno%20Esteves"> Bruno Esteves</a>, <a href="https://publications.waset.org/search?q=Lu%C3%ADsa%20P.%20Cruz-Lopes"> Luísa P.

These by-products, specifically almond and hazelnut shells are abundant in Portugal once almond and hazelnuts production is a local important activity. Hazelnut and almond shells have as main constituents lignin, cellulose and hemicelluloses, water soluble extractives and tannins. Along the adsorption of heavy metals from contaminated waters, water soluble compounds can leach from shells and have a negative impact in the environment. Usually, the chemical characterization of treated water by itself may not show environmental impact caused by the discharges when parameters obey to legal quality standards for water. Only biological systems can detect the toxic effects of the water constituents. Therefore, the evaluation of toxicity by biological tests is very important when deciding the suitability for safe water discharge or for irrigation applications.</p> <p>The main purpose of the present work was to assess the potential impacts of waters after been treated for heavy metal removal by hazelnut and almond shells adsorption systems, with short term acute toxicity tests.</p> <p>To conduct the study, water at pH 6 with 25 mg.L<sup>-1</sup> of lead, was treated with 10 g of shell per litre of wastewater, for 24 hours. This procedure was followed for each bark. Afterwards the water was collected for toxicological assays; namely bacterial resistance, seed germination, <em>Lemna minor </em>L. test and plant grow. The effect in isolated bacteria strains was determined by disc diffusion method and the germination index of seed was evaluated using lettuce, with temperature and humidity germination control for 7 days. For aquatic higher organism, Lemnas were used with 4 days contact time with shell solutions, in controlled light and temperature. For terrestrial higher plants, biomass production was evaluated after 14 days of tomato germination had occurred in soil, with controlled humidity, light and temperature.</p> <p>Toxicity tests of water treated with shells revealed in some extent effects in the tested organisms, with the test assays showing a close behaviour as the control, leading to the conclusion that its further utilization may not be considered to create a serious risk to the environment.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Acute%20toxicity%20tests"
