Appropriate composition of the multiplex has a major impact on how many videos is spread by multiplex. Therefore in this paper is designed a simple algorithm to optimize capacity utilization multiplex. Significant impact on the number of programs in the multiplex has also the fact from which programs is composed. Content of multiplex can be movies, news, sport, animated stories, documentaries, etc. These types have their own specific characteristics that affect their resulting data stream. In this paper is also done an impact analysis of the composition of the multiplex to use its capacity by video content. </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Multiplex" title="Multiplex">Multiplex</a>, <a href="https://publications.waset.org/search?q=content" title=" content"> content</a>, <a href="https://publications.waset.org/search?q=group%20of%20pictures" title=" group of pictures"> group of pictures</a>, <a href="https://publications.waset.org/search?q=frame" title=" frame"> frame</a>, <a href="https://publications.waset.org/search?q=capacity." title=" capacity."> capacity.</a> </p> <a href="https://publications.waset.org/17019/a-content-based-optimization-of-data-stream-television-multiplex" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/17019/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/17019/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/17019/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/17019/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/17019/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/17019/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/17019/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/17019/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/17019/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/17019/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/17019.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">1475</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">41</span> Video Quality Assessment using Visual Attention Approach for Sign Language</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Julia%20Kucerova">Julia Kucerova</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Polec"> Jaroslav Polec</a>, <a href="https://publications.waset.org/search?q=Darina%20Tarcsiova"> Darina Tarcsiova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Visual information is very important in human perception of surrounding world. Video is one of the most common ways to capture visual information. The video capability has many benefits and can be used in various applications. For the most part, the video information is used to bring entertainment and help to relax, moreover, it can improve the quality of life of deaf people. Visual information is crucial for hearing impaired people, it allows them to communicate personally, using the sign language; some parts of the person being spoken to, are more important than others (e.g. hands, face). Therefore, the information about visually relevant parts of the image, allows us to design objective metric for this specific case. In this paper, we present an example of an objective metric based on human visual attention and detection of salient object in the observed scene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=sign%20language" title="sign language">sign language</a>, <a href="https://publications.waset.org/search?q=objective%20video%20quality" title=" objective video quality"> objective video quality</a>, <a href="https://publications.waset.org/search?q=visual%20attention" title=" visual attention"> visual attention</a>, <a href="https://publications.waset.org/search?q=saliency" title=" saliency"> saliency</a> </p> <a href="https://publications.waset.org/14543/video-quality-assessment-using-visual-attention-approach-for-sign-language" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14543/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14543/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14543/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14543/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14543/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14543/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14543/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14543/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14543/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14543/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14543.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">1579</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">40</span> Key Frames Extraction for Sign Language Video Analysis and Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jaroslav%20Polec">Jaroslav Polec</a>, <a href="https://publications.waset.org/search?q=Petra%20Heribanov%C3%A1"> Petra Heribanová</a>, <a href="https://publications.waset.org/search?q=Tom%C3%A1%C5%A1%20Hirner"> Tomáš Hirner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we proposed a method for finding video frames representing one sign in the finger alphabet. The method is based on determining hands location, segmentation and the use of standard video quality evaluation metrics. Metric calculation is performed only in regions of interest. Sliding mechanism for finding local extrema and adaptive threshold based on local averaging is used for key frames selection. The success rate is evaluated by recall, precision and F1 measure. The method effectiveness is compared with metrics applied to all frames. Proposed method is fast, effective and relatively easy to realize by simple input video preprocessing and subsequent use of tools designed for video quality measuring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Key%20frame" title="Key frame">Key frame</a>, <a href="https://publications.waset.org/search?q=video" title=" video"> video</a>, <a href="https://publications.waset.org/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/search?q=metric" title=" metric"> metric</a>, <a href="https://publications.waset.org/search?q=MSE" title=" MSE"> MSE</a>, <a href="https://publications.waset.org/search?q=MSAD" title=" MSAD"> MSAD</a>, <a href="https://publications.waset.org/search?q=SSIM" title=" SSIM"> SSIM</a>, <a href="https://publications.waset.org/search?q=VQM" title=" VQM"> VQM</a>, <a href="https://publications.waset.org/search?q=sign%20language" title=" sign language"> sign language</a>, <a href="https://publications.waset.org/search?q=finger%20alphabet." title=" finger alphabet."> finger alphabet.</a> </p> <a href="https://publications.waset.org/2672/key-frames-extraction-for-sign-language-video-analysis-and-recognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/2672/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/2672/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/2672/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/2672/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/2672/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/2672/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/2672/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/2672/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/2672/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/2672/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/2672.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">2032</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">39</span> A Generator from Cascade Markov Model for Packet Loss and Subsequent Bit Error Description</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jaroslav%20Polec">Jaroslav Polec</a>, <a href="https://publications.waset.org/search?q=Viliam%20Hirner"> Viliam Hirner</a>, <a href="https://publications.waset.org/search?q=Michal%20Martinovi%C4%8D"> Michal Martinovič</a>, <a href="https://publications.waset.org/search?q=Kvetoslava%20Kotuliakov%C3%A1"> Kvetoslava Kotuliaková</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we present a novel error model for packet loss and subsequent error description.

The techniques presently used are not based on image elements but rather video objects having an arbitrary shape. In this paper, spatial shape error concealment techniques to be used for object-based image in error-prone environments are proposed. We consider a geometric shape representation consisting of the object boundary, which can be extracted from the α-plane. Three different approaches are used to replace a missing boundary segment: Bézier interpolation, Bézier approximation and NURBS approximation. Experimental results on object shape with different concealment difficulty demonstrate the performance of the proposed methods.

The proposed method makes a use of the features of video encoders like motion prediction. At first encoder selects appropriate prototype from the database and warps it according to features of encoding face. Warped prototype is placed as first I frame. Encoding face is placed as second frame as P frame type. Information about features positions, color change, selected prototype and data flow of P frame will be sent to decoder. The condition is both encoder and decoder own the same database of prototypes. We have run experiment with H.264 video encoder and obtained results were compared to results achieved by JPEG and JPEG2000. Obtained results show that our approach is able to achieve 3 times lower bitrate and two times higher PSNR in comparison with JPEG. According to comparison with JPEG2000 the bitrate was very similar, but subjective quality achieved by proposed method is better.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Triangulation" title="Triangulation">Triangulation</a>, <a href="https://publications.waset.org/search?q=H.264" title=" H.264"> H.264</a>, <a href="https://publications.waset.org/search?q=Model-based%20coding" title=" Model-based coding"> Model-based coding</a>, <a href="https://publications.waset.org/search?q=Average%0D%0Aface" title=" Average face"> Average face</a> </p> <a href="https://publications.waset.org/13528/face-image-coding-using-face-prototyping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13528/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13528/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13528/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13528/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13528/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13528/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13528/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13528/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13528/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13528/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13528.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">1725</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">32</span> Effect of PGPB Inoculation, Addition of Biochar, and Mineral N Fertilization on Mycorrhizal Colonization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Irina%20Mikajlo">Irina Mikajlo</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Z%C3%A1hora"> Jaroslav Záhora</a>, <a href="https://publications.waset.org/search?q=Helena%20Dvo%C5%99%C3%A1%C4%8Dkov%C3%A1"> Helena Dvořáčková</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Hyn%C5%A1t"> Jaroslav Hynšt</a>, <a href="https://publications.waset.org/search?q=Jakub%20Elbl"> Jakub Elbl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Strong anthropogenic impact has uncontrolled consequences on the nature of the soil.

Many studies reported the positive effect of biochar application on soil fertility and development of soil microbial community. Moreover biochar may affect the soil water retention, but this effect has not been sufficiently described yet. Therefore this study deals with the influence of biochar application on: microbial activities in soil, availability of mineral nitrogen in soil for microorganisms, mineral nitrogen retention and plant production. To demonstrate the effect of biochar addition on the above parameters, the pot experiment was realized. As a model crop, Lactuca sativa L. was used and cultivated from December 10th 2014 till March 22th 2015 in climate chamber in thoroughly homogenized arable soil with and without addition of biochar. Five variants of experiment (V1 – V5) with different regime of irrigation were prepared. Variants V1 – V2 were fertilized by mineral nitrogen, V3 – V4 by biochar and V5 was a control. The significant differences were found only in plant production and mineral nitrogen retention. The highest content of mineral nitrogen in soil was detected in V1 and V2, about 250 % in comparison with the other variants. The positive effect of biochar application on soil fertility, mineral nitrogen availability was not found. On the other hand results of plant production indicate the possible positive effect of biochar application on soil water retention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Arable%20soil" title="Arable soil">Arable soil</a>, <a href="https://publications.waset.org/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/search?q=mineral%20Nitrogen." title=" mineral Nitrogen."> mineral Nitrogen.</a> </p> <a href="https://publications.waset.org/10002120/the-potential-effect-of-biochar-application-on-microbial-activities-and-availability-of-mineral-nitrogen-in-arable-soil-stressed-by-drought" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10002120/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10002120/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10002120/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10002120/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10002120/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10002120/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10002120/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10002120/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10002120/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10002120/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10002120.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">2050</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">28</span> Effect of Organic-waste Compost Addition on Leaching of Mineral Nitrogen from Arable Land and Plant Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jakub%20Elbl">Jakub Elbl</a>, <a href="https://publications.waset.org/search?q=Lukas%20Plo%C5%A1ek"> Lukas Plošek</a>, <a href="https://publications.waset.org/search?q=Anton%C3%ADn%20Kintl"> Antonín Kintl</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Z%C3%A1hora"> Jaroslav Záhora</a>, <a href="https://publications.waset.org/search?q=Jitka%20P%C5%99ichystalov%C3%A1"> Jitka Přichystalová</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Hyn%C5%A1t"> Jaroslav Hynšt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Application of compost in agriculture is very desirable worldwide. In the Czech Republic, compost is the most often used to improve soil structure and increase the content of soil organic matter, but the effects of compost addition on the fate of mineral nitrogen are only scarcely described. This paper deals with possibility of using combined application of compost, mineral and organic fertilizers to reduce the leaching of mineral nitrogen from arable land. To demonstrate the effect of compost addition on leaching of mineral nitrogen, we performed the pot experiment. As a model crop, <em>Lactuca sativa</em> L. was used and cultivated for 35 days in climate chamber in thoroughly homogenized arable soil. Ten variants of the experiment were prepared; two control variants (pure arable soil and arable soil with added compost), four variants with different doses of mineral and organic fertilizers and four variants of the same doses of mineral and organic fertilizers with the addition of compos. The highest decrease of mineral nitrogen leaching was observed by the simultaneous applications of soluble humic substances and compost to soil samples, about 417% in comparison with the control variant. Application of these organic compounds also supported microbial activity and nitrogen immobilization documented by the highest soil respiration and by the highest value of the index of nitrogen availability. The production of plant biomass after this application was not the highest due to microbial competition for the nutrients in soil, but was 24% higher in comparison with the control variant. To support these promising results the experiment should be repeated in field conditions.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Nitrogen" title="Nitrogen">Nitrogen</a>, <a href="https://publications.waset.org/search?q=Compost" title=" Compost"> Compost</a>, <a href="https://publications.waset.org/search?q=Salad" title=" Salad"> Salad</a>, <a href="https://publications.waset.org/search?q=Arable%20land." title=" Arable land."> Arable land.</a> </p> <a href="https://publications.waset.org/17402/effect-of-organic-waste-compost-addition-on-leaching-of-mineral-nitrogen-from-arable-land-and-plant-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/17402/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/17402/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/17402/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/17402/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/17402/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/17402/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/17402/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/17402/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/17402/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/17402/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/17402.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">2070</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">27</span> Effects of Drought on Microbial Activity in Rhizosphere, Soil Hydrophobicity and Leaching of Mineral Nitrogen from Arable Soil Depending on Method of Fertilization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jakub%20Elbl">Jakub Elbl</a>, <a href="https://publications.waset.org/search?q=Luk%C3%A1%C5%A1%20Plo%C5%A1ek"> Lukáš Plošek</a>, <a href="https://publications.waset.org/search?q=Anton%C3%ADn%20Kintl"> Antonín Kintl</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Hyn%C5%A1t"> Jaroslav Hynšt</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Z%C3%A1hora"> Jaroslav Záhora</a>, <a href="https://publications.waset.org/search?q=So%C5%88a%20Javorekov%C3%A1"> Soňa Javoreková</a>, <a href="https://publications.waset.org/search?q=Ivana%20Charousov%C3%A1"> Ivana Charousová</a>, <a href="https://publications.waset.org/search?q=Libor%20Kalhotka"> Libor Kalhotka</a>, <a href="https://publications.waset.org/search?q=Olga%20Urb%C3%A1nkov%C3%A1"> Olga Urbánková </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This work presents the first results from the long-term laboratory experiment dealing with impact of drought on soil properties. Three groups of the treatment (A, B and C) with different regime of irrigation were prepared. The soil water content was maintained at 70 % of soil water holding capacity in group A, at 40 % in group B. In group C, soil water regime was maintained in the range of wilting point. Each group of the experiment was divided into three variants (A1 = B1, C1; A2 = B2, C2 etc.) with three repetitions: Variants A1 (B1, C1) were a controls without addition of another fertilizer. Variants A2 (B2, C2) were fertilized with mineral nitrogen fertilizer DAM 390 (0.140 Mg of N per ha) and variants A3 (B3, C3) contained 45 g of C<sub>p </sub>per a pot.</p> <p>The significant differences (ANOVA, P<0.05) in the leaching of mineral nitrogen and values of saturated hydraulic conductivity (K<sub>sat</sub>) were found. The highest values of K<sub>sat </sub>were found in variants (within each group) with addition of compost (A3, B3, C3). Conversely, the lowest values of K<sub>sat</sub> were found in variants with addition of mineral nitrogen. Low values of K<sub>sat</sub> indicate an increased level of hydrophobicity in individual groups of the experiment. Moreover, all variants with compost addition showed lower amount of mineral nitrogen leaching and high level of microbial activity than variants without. This decrease of mineral nitrogen leaching was about 200 % in comparison with the control variant and about 300 % with variant, where mineral nitrogen was added. Based on these results, we can conclude that changes of soil water content directly have impact on microbial activity, soil hydrophobicity and loss of mineral nitrogen from soil. </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Drought" title="Drought">Drought</a>, <a href="https://publications.waset.org/search?q=Microbial%20activity" title=" Microbial activity"> Microbial activity</a>, <a href="https://publications.waset.org/search?q=Mineral%20nitrogen" title=" Mineral nitrogen"> Mineral nitrogen</a>, <a href="https://publications.waset.org/search?q=Soil%20hydrophobicity." title=" Soil hydrophobicity."> Soil hydrophobicity.</a> </p> <a href="https://publications.waset.org/9999065/effects-of-drought-on-microbial-activity-in-rhizosphere-soil-hydrophobicity-and-leaching-of-mineral-nitrogen-from-arable-soil-depending-on-method-of-fertilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999065/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999065/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999065/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999065/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999065/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999065/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999065/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999065/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999065/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999065/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999065.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">3005</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">26</span> Intelligibility of Cued Speech in Video</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=P.%20Heribanov%C3%A1">P.

Cued speech is a specific gesture language that is used for communication between deaf people. We define the criteria for sentence intelligibility according to answers of testing subjects (deaf people). In our tests we use 30 sample videos coded by H.264 codec with various bit-rates and various speed of cued speech. Additionally, we define the criteria for consonant sign recognizability in single-handed finger alphabet (dactyl) analogically to acoustics. We use another 12 sample videos coded by H.264 codec with various bit-rates in four different video formats. To interpret the results we apply the standard scale for subjective video quality evaluation and the percentual evaluation of intelligibility as in acoustics. From the results we construct the minimum coded bit-rate recommendations for every spatial resolution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=cued%20speech" title="cued speech">cued speech</a>, <a href="https://publications.waset.org/search?q=inteligibility" title=" inteligibility"> inteligibility</a>, <a href="https://publications.waset.org/search?q=logatom" title=" logatom"> logatom</a>, <a href="https://publications.waset.org/search?q=video" title=" video"> video</a> </p> <a href="https://publications.waset.org/8119/intelligibility-of-cued-speech-in-video" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/8119/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/8119/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/8119/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/8119/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/8119/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/8119/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/8119/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/8119/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/8119/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/8119/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/8119.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">1530</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">25</span> Unequal Error Protection for Region of Interest with Embedded Zerotree Wavelet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=T.%20Hirner">T.

ROI technique is important in applications with different parts of importance. In ROI coding, a chosen ROI is encoded with higher quality than the background (BG). Unequal error protection of image is provided by different coding techniques. In our proposed method, image is divided into two parts (ROI, BG) that consist of more important bytes (MIB) and less important bytes (LIB). The experimental results verify effectiveness of the design. The results of our method demonstrate the comparison of the unequal error protection (UEP) of image transmission with defined ROI and the equal error protection (EEP) over multiple noisy channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=embedded%20zerotree%20wavelet%20%28EZW%29" title="embedded zerotree wavelet (EZW)">embedded zerotree wavelet (EZW)</a>, <a href="https://publications.waset.org/search?q=equal%20error%0Aprotection%20%28EEP%29" title=" equal error protection (EEP)"> equal error protection (EEP)</a>, <a href="https://publications.waset.org/search?q=region%20of%20interest%20%28ROI%29" title=" region of interest (ROI)"> region of interest (ROI)</a>, <a href="https://publications.waset.org/search?q=RS%20code" title=" RS code"> RS code</a>, <a href="https://publications.waset.org/search?q=unequal%20error%0Aprotection%20%28UEP%29" title=" unequal error protection (UEP)"> unequal error protection (UEP)</a> </p> <a href="https://publications.waset.org/15229/unequal-error-protection-for-region-of-interest-with-embedded-zerotree-wavelet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/15229/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/15229/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/15229/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/15229/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/15229/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/15229/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/15229/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/15229/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/15229/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/15229/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/15229.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">1470</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">24</span> The Effects of a Thin Liquid Layer on the Hydrodynamic Machine Rotor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jaroslav%20Krutil">Jaroslav Krutil</a>, <a href="https://publications.waset.org/search?q=Franti%C5%A1ek%20Pochyl%C3%BD"> František Pochylý</a>, <a href="https://publications.waset.org/search?q=Simona%20Fialov%C3%A1"> Simona Fialová</a>, <a href="https://publications.waset.org/search?q=Vladim%C3%ADr%20Hab%C3%A1n"> Vladimír Habán</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A mathematical model of the additional effects of the liquid in the hydrodynamic gap is presented in the paper.

However, PVB has similar chemical properties such as PVC. Moreover, both of these polymers are plasticized. Therefore, the study of thermal properties of plasticized PVC and the recycled PVB obtained by recycling of windshields is carried out. This work has done in order to find nondegradable processing conditions applicable for both polymers. Tested PVC contained 38% of plasticizer diisononyl phthalate (DINP) and PVB was plasticized with 28% of triethylene glycol, bis(2-ethylhexanoate) (3GO). The thermal and thermo-oxidative decomposition of both vinyl polymers are compared by calorimetric analysis and by tensile strength analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Poly%28vinyl%20chloride%29" title="Poly(vinyl chloride)">Poly(vinyl chloride)</a>, <a href="https://publications.waset.org/search?q=Poly%28vinyl%20butyral%29" title=" Poly(vinyl butyral)"> Poly(vinyl butyral)</a>, <a href="https://publications.waset.org/search?q=Recycling" title=" Recycling"> Recycling</a>, <a href="https://publications.waset.org/search?q=Reprocessing" title=" Reprocessing"> Reprocessing</a>, <a href="https://publications.waset.org/search?q=Thermal%20analysis" title=" Thermal analysis"> Thermal analysis</a>, <a href="https://publications.waset.org/search?q=Decomposition." title=" Decomposition."> Decomposition.</a> </p> <a href="https://publications.waset.org/10001710/comparison-of-processing-conditions-for-plasticized-pvc-and-pvb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10001710/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10001710/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10001710/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10001710/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10001710/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10001710/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10001710/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10001710/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10001710/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10001710/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10001710.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">5388</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">16</span> Fuzzy Modeling Tool for Creating a Component Model of Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Bogdan%20Walek">Bogdan Walek</a>, <a href="https://publications.waset.org/search?q=Jiri%20Bartos"> Jiri Bartos</a>, <a href="https://publications.waset.org/search?q=Cyril%20Klimes"> Cyril Klimes</a>, <a href="https://publications.waset.org/search?q=Jaroslav%20Prochazka"> Jaroslav Prochazka</a>, <a href="https://publications.waset.org/search?q=Pavel%20Smolka"> Pavel Smolka</a>, <a href="https://publications.waset.org/search?q=Juraj%20Masar"> Juraj Masar</a>, <a href="https://publications.waset.org/search?q=Martin%20Pesl"> Martin Pesl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper focuses on creating a component model of information system under uncertainty.
