No full textGiyilebilir sensörler ve kamera tabanlı cihazlar gibi modern teknolojiler, temassız müzik performanslarına olanak tanıyan Müzikal İfade için Yeni Arayüzler (MİYA) kapsamında olan çeşitli jest tabanlı kontrolörlerin geliştirilmesini sağlamıştır. Bu çalışma, MYO kol bandının MİYA bağlamındaki performansına odaklanmakta, özellikle kullanıcıların piyano ile fiziksel temas olmadan EMG sinyalleri aracılığıyla basit piyano parçaları çalmalarını sağlamaktadır. Piyano çalma sırasında kullanıcıların kol kaslarından EMG verileri toplanmış ve sınıflandırma için makine öğrenimi algoritmaları (SVM - Destek Vektör Makineleri, GB - Gradyan Güçlendirme ve RF - Rastgele Orman) kullanılmıştır. Sonuçlar, EMG sinyallerinin ön işleme sonrası GB algoritmasının %97,40 ile en yüksek doğruluğu elde ettiğini göstermiştir. Çalışmada elde edilen bulgular, MYO kol bandı gibi EMG tabanlı teknolojilerin etkileşimli müzik yapma deneyimini geliştirebileceğini ve doğrudan müzik performansına olanak sağlayabileceğini göstermektedir.</p
Spectral inspection, Hirshfeld surface, electronic and topological properties, Fukui functions in different solvents, 4-(4-ethyl-phenyl)-3-phenyl-1,2,4-oxadiazol-5(4H)-one – Anticonvulsant activities
No full textAn theoretical investigation of 4-(4-ethyl-phenyl)-3-phenyl-1,2,4-oxadiazol-5(4H)-one (EPPO) has been scrutinized utilizing the DFT/B3LYP/6-311++G(d,p) approach. Various analytical techniques, including X-ray, UV–visible, NMR and FT/IR, are elucidated by the synthesis and characterization of EPPO compound. The effect of solvents −chloroform, methanol, and water- on the structural parameters, spectroscopic properties (IR and UV–Vis), frontier molecular orbital (FMO), molecular electrostatic potential (MEP) surface, and topological properties of EPPO was investigated through theoretical calculations. The single crystal analysis indicates that the molecule is part of a monoclinic system with the spacegroup P21/c. Leveraging topological analyses like ELF, LOL, and RDG using gas and solvents chloroform, methanol and water have enabled the pinpointing of electrophilic and nucleophilic sites, offering a thorough comprehension of the distribution of charged particles across each element within the molecule. The impact of solvent on the UV–vis spectra of EPPO unveiled electronic transitions from π to π* and n to π* orbitals, accompanied by indications of intermolecular charge transfer (ICT) substantiated by analyses of FMO. A color-coded graphic representation of the MEP map for different solvent aspects was utilized to analyze the charge distribution within the molecule. The ADME properties of the newly synthesized molecule were investigated in detail, utilizing the smile code. The desired compound exhibited significant binding energies (−7.31 kcal/mol, −7.88 kcal/mol, −8.97 kcal/mol) against hGluA2, AChE, GABA-AT (PDB code: 3R7X, 4EY6, 1OHW) receptor proteins, suggesting potential candidate for further investigation in epilepsy
WebRT-LiDAR: platform-independent web-based real-time laser image detection and ranging mapping
No full textLaser image detection and ranging (LiDAR) data are used as an important source for monitoring the natural environment and environmental changes, forest management, transport, and urban development. Real-time LiDAR is especially useful in applications that require immediate feedback or decision-making, such as post-earthquake emergency analysis, autonomous vehicles, precision agriculture, military applications, and infrastructure monitoring. For instance, rapid and real-time assessment of structural damage following disasters like earthquakes ensures the effective use of resources by directing first responders to priority areas. We focused on minimizing the time losses in pre-flight preparation and post-flight data processing processes at the low-altitude LiDAR mapping. To eliminate time losses, LiDAR data, which can be accessed via a web browser, were visualized as a real-time 3D point cloud. The X3D file format was used in this visualization process. To realize the accessibility and sharing of the data, HTML5 technologies were used, and the data were transferred to the cloud system in real time. Thus, a user-friendly system was developed that can make these data available to researchers simultaneously. We designed and developed a platform-independent web-based real-time LiDAR (WebRT-LiDAR) mapping system. As an application, the performance of the WebRT-LiDAR mapping system was evaluated by integrating it into a drone (low-altitude Unmanned Aerial Vehicle) platform. The data received with this system can be stored in databases suitable for the use of artificial intelligence and machine learning–based systems. In this way, the system provides information, predictions, and capabilities that can be used in situations that require instant feedback or decision-making. In this context, the performance of the WebRT-LiDAR system can be further improved and tested in different scenarios, such as disaster management, war strategy, and efficient agriculture in future studies.</p
The effect of calcite on the mechanical, morphological and thermal properties of virgin and recycled thermoplastic copolyester elastomer composites
No full textIn this study, the effects of stearic acid-coated calcite (CaCO3) were investigated on the mechanical, thermal, and morphological properties of thermoplastic copolyester elastomers (COPE or TPE-E) and recycled COPEs (R-COPE). R-COPE, which consist of process wastes that are qualified as postindustrial recycled (PIR), were physically 100% recycled. The composites (virgin and recycled COPE) containing different concentrations of calcite (5-30 wt%) were prepared by melt compounding. It has been determined that mechanical properties such as impact strength and modulus increase with calcite concentration, while tensile strength decreases at higher concentrations owing to the stronger interfacial relationships between the polymer matrix and filler. Morphological studies revealed a good dispersion of calcite fillers at lower concentrations in the polymer matrix. The final composites obtained from recycled polymer had almost similar mechanical properties compared to virgin ones. This showed that recycled COPE could be used in many areas specifically automotive industry, as it gave results close to its original state with the addition of calcite with decreased cost.Highlights COPE were melt-blended with stearic acid-coated calcite (CaCO3). Recycled-COPEs were obtained from the physical recycling of factory production waste. The mechanical properties such as tensile modulus increased with calcite concentration. The thermal properties increased with increasing calcite concentration. R-COPE composites were obtained without any decrease in properties. The effect of calcite on the properties of virgin and recycled thermoplastic copolyester elastomer composites. imag

No full textHow does leadership team coherence affect collaborative learning and academic optimism in a centralized education system?
No full textAcademic optimism has been one of the important study subjects of researchers in recent years due to its impact on organizational variables and schools, especially in the field of educational management and leadership. This study aims to examine the mediating role of collaborative teacher professional learning and the moderating role of enabling school structure in the relationship between leadership team coherence and academic optimism. Therefore, the study was designed as a cross-sectional study in quantitative research method. And 1204 teachers working in 1204 public schools in 52 provinces in the west, middle, east, north, and south of T & uuml;rkiye, determined by stratified random sampling method, participated in the research. Results showed that collaborative teacher professional learning mediated the relationship between leadership team coherence and teachers' academic optimism. Additionally, the effect of leadership team coherence on collaborative teacher professional learning, and through collaborative teacher professional learning on academic optimism, was stronger when the enabling school structure was moderate and high. Our results provide evidence that in the Turkish school context, enabling school structure moderates the effect of leadership team cohesion on teachers' academic optimism through collaborative learning. Our research also provides valuable insights that can provide a framework for promoting collaboration and an enabling structure in schools
