Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-cleaning surfaces are getting significant attention in industrial fields. Especially for textile fabrics, it is observed that self-cleaning textile fabric surfaces are created by manipulating the surface features with the help of coatings and nanoparticles, which are considered costly and far more complicated. However, controlling the fabrication parameters of textile fabrics at the microscopic level by exploring the potential for self-cleaning has not been addressed. This study aimed to establish the context of self-cleaning textile fabrics by controlling the fabrication parameters of the textile fabric at the microscopic level. Therefore, 3D-printed textile fabrics were fabricated using the low-cost fused filament fabrication (FFF) technique. The printing parameters, such as orientation angle (O), layer height (LH), and extruder width (EW), were used to control the microscopic features of the printed fabrics. The combination of three printing parameters was created to provide the best self-cleaning textile fabric surface: (LH) (0.15, 0.13, 0.10 mm) and (EW) (0.5, 0.4, 0.3 mm) along with two different (O) of (45º and 90º). Three different thermoplastic flexible filament materials were used: (TPU 98A), (TPE felaflex), and (TPC flex45). The printing parameters were optimised to get the optimum self-cleaning ability of the printed specimens. Furthermore, the impact of these characteristics on mechanical strength at the fabric-woven structure level was investigated. The study revealed that the printing parameters significantly affect the self-cleaning properties after adjusting the selected combination of layer height, extruder width, and printing orientation. A linear regression model was effectively developed to demonstrate the association between 3D printing parameters (layer height, extruder width, and orientation). According to the experimental results, (TPE felaflex) has a better self-cleaning ability than the other two materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=self-cleaning%20fabric" title=" self-cleaning fabric"> self-cleaning fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopic%20features" title=" microscopic features"> microscopic features</a>, <a href="https://publications.waset.org/abstracts/search?q=printing%20parameters" title=" printing parameters"> printing parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=fabrication" title=" fabrication"> fabrication</a> </p> <a href="https://publications.waset.org/abstracts/168395/the-influence-of-microscopic-features-on-the-self-cleaning-ability-of-developed-3d-printed-fabric-like-structures-using-different-printing-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168395.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">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">131</span> Performance Based Road Asset Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kidus%20Dawit%20Gedamu">Kidus Dawit Gedamu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Addis Ababa City Road Authority is responsible for managing and setting performance evaluation of the city’s road network using the International Roughness Index (IRI). This helps the authority to conduct pavement condition assessments of asphalt roads each year to determine the health status or Level of service (LOS) of the roadway network and plan program improvements such as maintenance, resurfacing and rehabilitation. For a lower IRI limit economical and acceptable maintenance strategy may be selected among a number of maintenance alternatives. The Highway Development and Management (HDM-4) tool can do such measures to help decide which option is the best by evaluating the economic and structural conditions. This paper specifically addresses flexible pavement, including two principal arterial streets under the administration of the Addis Ababa City Roads Authority. The roads include the road from Megenagna Interchange to Ayat Square and from Ayat Square to Tafo RA. First, it was assessed the procedures followed by the city's road authority to develop the appropriate road maintenance strategies. Questionnaire surveys and interviews are used to collect information from the city's road maintenance departments. Second, the project analysis was performed for functional and economic comparison of different maintenance alternatives using HDM-4. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=appropriate%20maintenance%20strategy" title="appropriate maintenance strategy">appropriate maintenance strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20stream" title=" cost stream"> cost stream</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20deterioration" title=" road deterioration"> road deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20alternative" title=" maintenance alternative"> maintenance alternative</a> </p> <a href="https://publications.waset.org/abstracts/184132/performance-based-road-asset-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184132.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">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Characterization of the Soils of the Edough Massif (North East Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somia%20Lakehal%20Ayat">Somia Lakehal Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibtissem%20Samai"> Ibtissem Samai</a>, <a href="https://publications.waset.org/abstracts/search?q=Srara%20Lakehal%20Ayat"> Srara Lakehal Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaima%20Dahmani"> Chaima Dahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work relates to the physicochemical diversity and the characterization of the different types of soils of the edough massif (North East of Algeria) and to the evaluation and characterization of the existing organic matter as well as to the evolution. and the dynamics of the latter, also on its influence on changes in the physical properties of soils. In order to know the soil properties of seraidi forest, we established a stratified sampling plan. The results obtained show that we are in the presence of a great diversity of soils, such as neutral to alkaline, whose adsorbent complex is sufficiently saturated. Also, the presence of limestone offers the soil a fairly significant buffering capacity. In our study region, the texture of the soils is varied between clayey and silty, where it offers medium porosity, there is a strong accumulation of organic matter, therefore soils rich in organic matter.The fractionation of the organic matter of the soils allowed to obtain a very high rate of humification. The soil characteristics of the edough massif (North East of Algeria) are controlled by the contribution of organic matter, which presents a dynamic and an important evolution and which varies with the climatic conditions and the nature and the type of plant formation, and these the latter have a capital and important role in the rate of mineralization of organic matter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20matter" title="organic matter">organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=foresty" title=" foresty"> foresty</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralization" title=" mineralization"> mineralization</a> </p> <a href="https://publications.waset.org/abstracts/168523/characterization-of-the-soils-of-the-edough-massif-north-east-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168523.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">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">129</span> Investigation of NiO/V₂O₅ Powder Composite as Cathode Material for Lithium-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katia%20Ayouz-Chebout">Katia Ayouz-Chebout</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Boudeffar"> Fatima Boudeffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Ayat"> Maha Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Malika%20Berouaken"> Malika Berouaken</a>, <a href="https://publications.waset.org/abstracts/search?q=Chafiaa%20Yaddaden"> Chafiaa Yaddaden</a>, <a href="https://publications.waset.org/abstracts/search?q=Saloua%20Merazga"> Saloua Merazga</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouredine%20Gabouze"> Nouredine Gabouze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transition metal oxide composites have been widely reported in energy storage and conversion systems.

These parameters are the short circuit current (Jsc), the open circuit voltage (Voc), the fill factor (FF), the conversion efficiency. The simulation was performed with SCAPS-1D software version 3.3 developed at ELIS in Belgium by Marc Burgelman et al. The obtained results are in agreement with experiment. In addition, the effect of the thickness, doping density, capture cross sections of the gap states and the band microscopic mobilities on the output parameters of the cell are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amorphous%20silicon%20p-i-n%20junctions" title="amorphous silicon p-i-n junctions">amorphous silicon p-i-n junctions</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/21840/sensitivity-studies-for-a-pin-homojunction-a-sih-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21840.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">521</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">123</span> Scalable Cloud-Based LEO Satellite Constellation Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Sobh">Karim Sobh</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20El-Ayat"> Khaled El-Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Fady%20Morcos"> Fady Morcos</a>, <a href="https://publications.waset.org/abstracts/search?q=Amr%20El-Kadi"> Amr El-Kadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distributed applications deployed on LEO satellites and ground stations require substantial communication between different members in a constellation to overcome the earth coverage barriers imposed by GEOs. Applications running on LEO constellations suffer the earth line-of-sight blockage effect. They need adequate lab testing before launching to space. We propose a scalable cloud-based net-work simulation framework to simulate problems created by the earth line-of-sight blockage. The framework utilized cloud IaaS virtual machines to simulate LEO satellites and ground stations distributed software. A factorial ANOVA statistical analysis is conducted to measure simulator overhead on overall communication performance. The results showed a very low simulator communication overhead. Consequently, the simulation framework is proposed as a candidate for testing LEO constellations with distributed software in the lab before space launch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LEO" title="LEO">LEO</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=constellation" title=" constellation"> constellation</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite" title=" satellite"> satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20simulation" title=" network simulation"> network simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=netfilter" title=" netfilter"> netfilter</a> </p> <a href="https://publications.waset.org/abstracts/23478/scalable-cloud-based-leo-satellite-constellation-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23478.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">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> A New Internal Architecture Based On Feature Selection for Holonic Manufacturing System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jihan%20Abdulazeez%20%20Ahmed">Jihan Abdulazeez Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Mohsin%20Abdulazeez%20Brifcani"> Adnan Mohsin Abdulazeez Brifcani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper suggests a new internal architecture of holon based on feature selection model using the combination of Bees Algorithm (BA) and Artificial Neural Network (ANN).

Neurons were classified based on differences in size and shape of their cell bodies, density of their dendritic trees, morphology and distribution of their appendages. In the spinal trigeminal nucleus of the camel, at least twelve types of neurons were identified. These neurons include, stalked, islets, octubus-like, lobulated, boat-like, pyramidal, multipolar, round, oval and elongated neurons. They have large number of different forms of appendages not only for their dendrites but also for their cell bodies. Neurons with unique large dilatations especially at their dendritic branching points were found. The morphological features of these neurons were described and compared with their counterparts in other species. Finding of large number of neuronal types with different size and shapes and large number of different forms of appendages for cell bodies and dendrites together with the presence of cells with unique features such as large dilated parts for dendrites may indicate to a very complex information processing for pain and temperature at the level of the spinal trigeminal nucleus in the camel that traditionally live in a very hard environment (the desert). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camel" title="camel">camel</a>, <a href="https://publications.waset.org/abstracts/search?q=golgi" title=" golgi"> golgi</a>, <a href="https://publications.waset.org/abstracts/search?q=neurons" title=" neurons "> neurons </a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20trigeminal%20nucleus" title=" spinal trigeminal nucleus"> spinal trigeminal nucleus</a> </p> <a href="https://publications.waset.org/abstracts/30990/types-of-neurons-in-the-spinal-trigeminal-nucleus-of-the-camel-brain-golgi-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30990.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">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">119</span> Adaptive Routing Protocol for Dynamic Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fayez%20Mostafa%20Alhamoui">Fayez Mostafa Alhamoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Hadi%20Mahdi%20Al-%20Helali"> Adnan Hadi Mahdi Al- Helali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main issue in designing a wireless sensor network (WSN) is the finding of a proper routing protocol that complies with the several requirements of high reliability, short latency, scalability, low power consumption, and many others. This paper proposes a novel routing algorithm that complies with these design requirements. The new routing protocol divides the WSN into several sub-networks and each sub-network is divided into several clusters. This division is designed to reduce the number of radio transmission and hence decreases the power consumption. The network division may be changed dynamically to adapt with the network changes and allows the realization of the design requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title="wireless sensor networks">wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=routing%20protocols" title=" routing protocols"> routing protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=AD%20HOC%20topology" title=" AD HOC topology"> AD HOC topology</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster" title=" cluster"> cluster</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-network" title=" sub-network"> sub-network</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN%20design%20requirements" title=" WSN design requirements"> WSN design requirements</a> </p> <a href="https://publications.waset.org/abstracts/37365/adaptive-routing-protocol-for-dynamic-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37365.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">537</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">118</span> Quick Similarity Measurement of Binary Images via Probabilistic Pixel Mapping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adnan%20A.%20Y.%20Mustafa">Adnan A.

The technique is based on a probabilistic mapping approach and is fast because only a minute percentage of the image pixels need to be compared to measure the similarity, and not the whole image. We exploit the power of the Probabilistic Matching Model for Binary Images (PMMBI) to arrive at an estimate of the similarity. We show that the estimate is a good approximation of the actual value, and the quality of the estimate can be improved further with increased image mappings. Furthermore, the technique is image size invariant; the similarity between big images can be measured as fast as that for small images.

The intermetallics have been fractured during thixoforming. It is believed that the fine distribution of the intermetallics is one mechanism for the improved mechanical properties of Thixoformed alloys.

However, the presence of speckle noise, which is a form of multiplicative noise, poses a significant obstacle to obtaining clear and accurate images in ultrasound imaging. Speckle noise reduces image quality by decreasing contrast, resolution, and signal-to-noise ratio (SNR). This makes it difficult for medical professionals to interpret ultrasound images accurately. To address this issue, various techniques have been developed to reduce speckle noise in ultrasound images, which improves image quality. This paper aims to review some of these techniques, highlighting the advantages and disadvantages of each algorithm and identifying the scenarios in which they work most effectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title="image processing">image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=speckle" title=" speckle"> speckle</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/166509/review-of-ultrasound-image-processing-techniques-for-speckle-noise-reduction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166509.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">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">112</span> Pre-Operative Tool for Facial-Post-Surgical Estimation and Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayat%20E.%20Ali">Ayat E.

Methods: To this aim, we implemented a software which used data from the internet for facial skin diseases, skin burns, pre-and post-images for plastic surgeries then the post- surgical prediction is done by using K-nearest neighbor (KNN). So we designed and fabricated a smart mirror divided into two parts a screen and a reflective mirror so patient's pre- and post-appearance will be showed at the same time. Results: We worked on some skin diseases like vitiligo, skin burns and wrinkles. We classified the three degrees of burns using KNN classifier with accuracy 60%. We also succeeded in segmenting the area of vitiligo. Our future work will include working on more skin diseases, classify them and give a prediction for the look after the surgery. Also we will go deeper into facial deformities and plastic surgeries like nose reshaping and face slim down. Conclusion: Our project will give a prediction relates strongly to the real look after surgery and decrease different diagnoses among doctors. Significance: The mirror may have broad societal appeal as it will make the distance between patient's satisfaction and the medical standards smaller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=k-nearest%20neighbor%20%28knn%29" title="k-nearest neighbor (knn)">k-nearest neighbor (knn)</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20detection" title=" face detection"> face detection</a>, <a href="https://publications.waset.org/abstracts/search?q=vitiligo" title=" vitiligo"> vitiligo</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20deformity" title=" bone deformity"> bone deformity</a> </p> <a href="https://publications.waset.org/abstracts/108026/pre-operative-tool-for-facial-post-surgical-estimation-and-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108026.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">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">111</span> Underivatized Amino Acid Analyses Using Liquid Chromatography-Tandem Mass Spectrometry in Scalp Hair of Children with Autism Spectrum Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Bani%20Rashaid">Ayat Bani Rashaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Zain%20Khasawneh"> Zain Khasawneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mazin%20Alqhazo"> Mazin Alqhazo</a>, <a href="https://publications.waset.org/abstracts/search?q=Shreen%20Nusair"> Shreen Nusair</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20El-Khateeb"> Mohammad El-Khateeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Bashtawi"> Mahmoud Bashtawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autism Spectrum disorder (ASD) is a psychiatric disorder with unknown etiology that mainly affects children in the first three years of life. Alterations of amino acid levels are believed to contribute to ASD. The levels of six essential amino acids (methionine, histidine, valine, leucine, threonine, and phenylalanine), five conditional amino acids (proline, tyrosine, glutamine, cysteine, and cystine), and five non-essential amino acids (asparagine, aspartic acid, alanine, serine, and glutamic acid) in hair samples of children with ASD (n = 25) were analyzed and compared to corresponding levels in healthy age-matched controls (n = 25). The results showed that the levels of methionine, alanine, and asparagine were significantly lower in the hair samples of ASD group compared to those of the control group (p ≤ 0.05). However, the levels of glutamic acid were significantly higher in the ASD group than the control group (p ≤ 0.05). The current findings could contribute towards further understanding of ASD etiology and provide specialists with a hair amino acid profile utilized as a biomarker for early diagnosis of ASD. Such biomarkers could participate in future developments of therapies that reduce ASD-related symptoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=amino%20acids" title=" amino acids"> amino acids</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20chromatography-tandem%20mass%20spectrometry" title=" liquid chromatography-tandem mass spectrometry"> liquid chromatography-tandem mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20hair" title=" human hair"> human hair</a> </p> <a href="https://publications.waset.org/abstracts/128805/underivatized-amino-acid-analyses-using-liquid-chromatography-tandem-mass-spectrometry-in-scalp-hair-of-children-with-autism-spectrum-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128805.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">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">110</span> A Novel Image Steganography Scheme Based on Mandelbrot Fractal </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adnan%20H.%20M.%20Al-Helali">Adnan H.

It is mentally challenging to maneuver an aircraft, and pilots must control the aircraft and adequately communicate to the verbal-auditory stimuli. Several physiological measures have long been researched and used to demonstrate the cognitive workload. In our current study, we have summarized recent findings of the effectiveness, accuracy, and applicability of commonly used physiological measures in evaluating cognitive workload. We have also highlighted on the advancements in physiological measures. The strength and limitations of physiological measures have also been discussed to assess the cognitive workload of people, especially the aircrews in laboratory settings and real-time situations. We have presented the research findings of the physiological measures to base suggestions on the proper applications of the measures and settings demanding the use of single measure or their combinations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircrew" title="aircrew">aircrew</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20workload" title=" cognitive workload"> cognitive workload</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20measure" title=" subjective measure"> subjective measure</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20measure" title=" physiological measure"> physiological measure</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20measure" title=" performance measure"> performance measure</a> </p> <a href="https://publications.waset.org/abstracts/137265/a-review-of-physiological-measures-for-cognitive-workload-assessment-of-aircrew" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137265.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">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">106</span> Effect of Superabsorbent for the Improvement of Car Seat's Thermal Comfort</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Funda%20Buyuk%20Mazari">Funda Buyuk Mazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Mazari"> Adnan Mazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonin%20Havelka"> Antonin Havelka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Wiener"> Jakub Wiener</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawad%20Naeem"> Jawad Naeem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of super absorbent polymers (SAP) for moisture absorption and comfort is still unexplored.

Sweating guarded hot plate (SGHP) from company Atlas is used to determine the moisture permeability of different car seat cover with superabsorbent layer closed with impermeable polyurethane foam. It is observed that the SAP fibrous layers are very effective in absorbing and desorbing water vapor under extreme high and low moisture percentages respectively. In extreme humid condition (95 %RH) the 20g of SAP layer absorbs nearly 3g of water vapor per hour and reaches the maximum absorption capacity in 6 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=car%20seat" title="car seat">car seat</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort" title=" comfort"> comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=SAF" title=" SAF"> SAF</a>, <a href="https://publications.waset.org/abstracts/search?q=superabsorbent" title=" superabsorbent"> superabsorbent</a> </p> <a href="https://publications.waset.org/abstracts/43231/effect-of-superabsorbent-for-the-improvement-of-car-seats-thermal-comfort" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43231.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">475</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">105</span> Improving Library Service Quality in Local City of Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prima%20Fithri">Prima Fithri</a>, <a href="https://publications.waset.org/abstracts/search?q=Afri%20Adnan"> Afri Adnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Verra%20Syahmer"> Verra Syahmer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Library as a public service should be able to provide excellent and quality service.

The algorithm mimics the mechanism of color changing behavior of the cuttlefish to solve numerical global optimization problems. The colors and patterns of the cuttlefish are produced by reflected light from three different layers of cells. The proposed algorithm considers mainly two processes: reflection and visibility. Reflection process simulates light reflection mechanism used by these layers, while visibility process simulates visibility of matching patterns of the cuttlefish. To show the effectiveness of the algorithm, it is tested with some other popular bio-inspired optimization algorithms such as Genetic Algorithms (GA), Particle Swarm Optimization (PSO) and Bees Algorithm (BA) that have been previously proposed in the literature.

This research utilized a cross-sectional descriptive study to assess postpartum depression prevalence and identify contributing factors in Pasil, utilizing a quantitative approach and collecting data on sociodemographic characteristics, obstetric data, and the Edinburgh Postnatal Depression Scale. The study concluded that probable depression can be seen among mothers in the Pasil, which resulted in a risk of suicidality with a percentage of 40.08. Additionally, most of the respondents are aged 28–32, married, have a college degree, are unemployed, have a monthly income of 1,000–5,000, are female, have hypertension, gave birth naturally, have two children, have a planned pregnancy, and are currently breastfeeding. Lastly, the study found that mothers in Pasil who have unplanned pregnancies under obstetric factors are at high risk of developing postpartum depression, with a p-value below the 0.05 level. The study recommends barangay health professionals develop initiatives to inform aspiring mothers about postpartum depression (PPD) and resources to help them adjust to motherhood. It also recommends frequent check-ins with new mothers to identify special healthcare needs. Programs should be independently funded by LGUs, and support from family and relatives is recommended to prevent PPD. <p class="card-text"><strong>Keywords:</strong> <a
