Published: December 2022

Ketika model jaringan saraf tiruan menjadi lebih baik , keinginan untuk mengimplementasikannya di dunia nyata semakin meningkat. Namun, konsumsi energi dan akurasi jaringan saraf tiruan sangat besar karena ukuran dan kompleksitasnya, sehingga sulit untuk diimplementasikan pada embedded devices. Kuantisasi jaringan saraf ini adalah sebuah teknik untuk dapat memecahkan masalah seperti mengurangi ukuran dan kompleksitas jaringan saraf tiruan dengan mengurangi ketepatan parameter dan aktivasi. Dengan jaringan yang lebih kecil, dimungkinkan untuk menjalankan jaringan saraf di lokasi yang diinginkan. Artikel ini mengkaji tentang kuantisasi yang telah berkembang dalam beberapa dekade terakhir. Dalam penelitian ini, kami mengimplementasikan kuantisasi dalam algoritma lenet-5, yang merupakan algoritma jaringan saraf convolutional pertama yang pernah ada, dan dievaluasi dalam dataset MNIST dan Fashion-MNIST.

Aplikasi Fuzzy Piction adalah aplikasi prediksi kandungan pigmen tanaman berbasis android yang dikembangkan oleh kelompok riset Precision Agriculture, Universitas Ma Chung Malang. Aplikasi mampu memprediksi kandungan 3 macam pigmen fotosintesis utama yaitu klorofil, karotenoid, dan antosianin secara non destruktif melalui citra daun tanaman yang sedang dievaluasi. Model prediksi dikembangkan dengan metode Convolutional Neural Network (CNN). Aplikasi menghadapi permasalahan akurasi yang terjadi karena variasi iluminasi di lapangan saat evaluasi terhadap tanaman dilakukan secara in-situ. Untuk menyelesaikan permasalahan tersebut, pada penelitian ini diimplementasikan metode perbaikan citra berbasis kecerdasan buatan yaitu KNN (K-Nearest Neighbor) dan ANN (Artificial Neural Network). Hasil eksperimen menunjukan bahwa metode KNN mampu memberikan perbaikan citra yang lebih baik. Indikator lebih baik dilihat dari presisi nilai prediksi pigmen dari beberapa citra pada iluminasi yang berbeda untuk objek tanaman yang sama. Nilai standar deviasi prediksi pigmen pada citra-citra hasil perbaikan dengan KNN berada pada kisaran 0,001 hingga 0,026 sedangkan dengan ANN berada pada kisaran 0,005 hingga 0,557. Sampel tanaman yang digunakan pada penelitian ini adalah Duranta Erecta dan Piper Betle.
Transformer vs. CNN – A Comparison on Knee Segmentation in Ultrasound Images
Authors: Brößner Peter , Hohlmann Benjamin , Radermacher Klaus 
Published: December 2022

The automated and robust segmentation of bone surfaces in ultrasound (US) images can open up new fields of application for US imaging in computer-assisted orthopedic surgery, e.g. for the patient-specific planning process in computer-assisted knee replacement. For the automated, deep learning-based segmentation of medical images, CNN-based methods have been the state of the art over the last years, while recently Transformer-based methods are on the rise in computer vision. To compare these methods with respect to US image segmentation, in this paper the recent Transformer- based Swin-UNet is exemplarily benchmarked against the commonly used CNN-based nnUNet on the application of in-vivo 2D US knee segmentation.Trained and tested on our own dataset with 8166 annotated images (split in 7155 and 1011 images respectively), both the nnUNet and the pre-trained Swin-UNet show a Dice coefficient of 0.78 during testing. For distances between skeletonized labels and predictions, a symmetric Hausdorff distance of 44.69 pixels and a symmetric surface distance of 5.77 pixels is found for nnUNet as compared to 42.78 pixels and 5.68 pixels respectively for the Swin-UNet. Based on qualitative assessment, the Transformer-based Swin-UNet appears to benefit from its capability of learning global relationships as compared to the CNN-based nnUNet, while the latter shows more consistent and smooth predictions on a local level, presumably due to the character of convolution operation. Besides, the Swin-UNet requires generalized pre-training to be competitive.Since both architectures are evenly suited for the task at hand, for our future work, hybrid architectures combining the characteristic advantages of Transformer-based and CNN-based methods seem promising for US image segmentation.

Published: December 2022

Background: The rapid increase in the popularity of internet use and video games is associated with multiple consequences and comorbidities; therefore, investigating this issue is important, especially now that the number of people playing video games has reached approximately 2.2 billion people worldwide. Method: This paper reviews the existing literature on Google Scholar and PubMed to examine the association between internet gaming disorder (IGD) and attention deficit hyperactivity disorder (ADHD) between 2013 and 2020. Result: The reviewed studies reveal a statistically significant association between ADHD and IGD. The reviewed studies demonstrate that ADHD is a predictive factor for the development and persistence of IGD and affects the severity of IGD symptoms. Conclusion: Especially among those with ADHD, IGD causes life distress and social life impairment. This review indicates a statistically significant association between ADHD and IGD; however, longitudinal studies are needed to assist the direction of this association and make relevant and appropriate recommendations to prevent its consequences and comorbidities.

Authors: YİĞİT Neslihan Huri 
Published: December 2022

Askerlik, Türk milleti için peygamber ocağı sayılan, erkekler için asıl hayatın başladığı, öncesi ve sonrasıyla önemli bir eşik kabul edilen önemli bir olgudur. Her ne kadar askere gitmek ve asker olmak erkekler nezdinde yaşanan bir durum gibi görünse de, dolaylı olarak aile kurumunu, kadınları (anne, eş, evlat, kardeş gibi) ve toplumsal yapıyı da etkileyen bir forma sahiptir. Erkeğin iş gücü olarak aileden uzaklaşması, kadınların hasretliği ve gurbeti duygusal olarak babaya, abiye göre daha derinden yaşaması ve yansıtması, toplumun askerliğini yapan ile yapmamış olana bakışı (iş verme, evlenme, olgunlaşma/erginlenme bakımından) gibi olgular askerlik etrafında şekillenen durumlardan sadece birazıdır. Askerlik ile toplumsal yapı arasındaki bu etkileşim, askerliğin hukuki statüsü dışında folklorik bir dünyanın meydana gelmesine de aracılık etmiştir. Bu dünyanın en geniş yansımasını “türkü” formuyla yakılmış ezgilerde bulmak mümkündür.
Bu çalışmada türkü metinlerinden yola çıkarak askerlik olgusu, şu başlıklar etrafında irdelenecektir: Askere gitme ve asker gönderme aşamasında yaşananlar, askerlik süresince yaşananlar, asker tarafından ve ailesi tarafından çekilen hasretin ifade edilişi, geride kalanlarca askerlik kurumuna dair yakınmaların türkülere yansıması, gurur kaynağı olarak Mehmetçiğin ve vatanın türkülere yansıması, şehitlik mertebesi ile ilgili türküler, askerlikle ilgili terimlerin türkülere yansıması. Eldeki verilerin genişliği dikkate alınarak çalışma TRT repertuarına kayıtlı türkülerle sınırlandırılmıştır.

Inelastic Deformation of Freestanding Plasma-Sprayed Thermal Barrier Coatings
Authors: Arai M. , Wu X.H. , Fujimoto K. 
Published: December 2022

Abstract
A fundamental study of inelastic deformation of freestanding plasma-sprayed thermal barrier coatings (TBCs) has been conducted. Cantilever-type bending tests are carried out to obtain stress-strain curves from freestanding ceramic layers detached from the TBC-coated sample via electrochemical treatment. In order to investigate inelastic deformation in the sample, in-situ scanning electron microscope (SEM) observation is performed by means of a small tensile testing device that can be inserted into the SEM vacuum chamber. The bending test result indicated that the coating deforms with a nonlinear behavior under monotonic loading, in spite of the fact that it is a ceramic material. Spray parameters such as in-flight velocity affected the stress-strain curve significantly. In-situ SEM observation during the bending test revealed that sliding at boundaries between splats plays an important role in inelastic deformation.

Published: December 2022

Abstract
This paper presents a method, based on push-rod type thermomechanical analysis, for determining the thermal expansion behavior of thermal barrier coatings (TBCs). It shows that TMA measurements can provide accurate CTEs for yttria-stabilized zirconia layers as thin as 0.3 mm with good reproducibility and low measurement error (&lt; 5%). The method was also used to assess the effect of annealing on thermal expansion behavior, revealing a slightly monotonic decrease in the CTE of YSZ samples.

Published: December 2022

Abstract
Thermal barrier coatings (TBCs) consisting of a yttria-partially-stabilized zirconia (YSZ) topcoat and a metallic bond coat are used to protect components in high temperature environments such as the hot section of a gas turbine. In this study, the bond coats have been fabricated using different thermal spray processes, including vacuum arc spaying, high-velocity oxyfuel flame spraying, low-pressure plasma spraying, air plasma spraying, and detonation spraying. The microstructure of the resulting TBCs is characterized based on XRD, SEM, and TEM analysis and various properties are measured, including high-temperature oxidation, cohesion strength, thermal impact, and heat insulation temperature.
Microstructure-Based Prediction of Properties for Thermal Barrier Coatings
Authors: Qunbo Fan , Fuchi Wang , Lu Wang , Zhuang Ma 
Published: December 2022

Abstract
In this work, digital image processing and finite element analysis are used to predict physical properties of thermal barrier coatings based on microstructure. Factors that affect thermal conductivity such as porosity, crack morphology, and interface defects are systematically studied. It is shown that transverse cracks can significantly retard the transfer of thermal flux and that the effective TCE and elastic modulus at the coating interface is determined mainly by composition, with interface morphology having little effect. Furthermore, no anisotropy was found at the interface. Unlike traditional property-prediction methods, the methodology presented in this paper reflects real coating microstructures, thus providing more accurate results.

Published: December 2022

Abstract
Thermal conductivity of plasma-sprayed YSZ thermal barrier coatings depends on microstructure and significantly influences the effectiveness of the thermal barrier. In this study, YSZ coatings are deposited by plasma spraying using fused and crushed Y2O3-ZrO2 powder. Coating microstructure was modified by substrate temperature, which was varied from room temperature to 880 °C during deposition. The coating microstructure was examined from the fractured cross-section of the deposits to reveal changes in interlamellar bonding due to substrate temperature. The thermal conductivities of the YSZ coating were tested by laser flashing from room temperature to 1300 °C. The results showed that the coating deposited at room temperature exhibited a typical lamellar structure and a thermal conductivity of 1.26 W·m-1·K-1 measured at room temperature. With the increase of substrate temperature, the thermal conductivity was increased. The coating deposited at a substrate temperature of 840-880 °C consisted of trans-lamellae long columnar grains and exhibited a value of 1.95 W·m-1·K-1 at room temperature. The influence of substrate temperature on thermal conductivity is discussed based on the changes in microstructure observed.

Authors: Michaux P. , Montavon G. , Grimaud A. , Denoirjean A. , Fauchais P. 
Published: December 2022

Abstract
In this study, nickel-zirconia cermet layers are produced by solution precursor plasma spraying (SPPS) and compared with suspension plasma sprayed (SPS) coatings of similar content. Although nickel is uniformly distributed in both coatings, its presence in the suspension caused problems with the SPS process. With the SSPS process, precursor solutions are fragmented into droplets in which Ni, Zr, and Y are intimately mixed, resulting in very fine microstructure without the problems encountered with the SPS process. It was also found that plasma gas enthalpy and spray distance have predominant effects on in-flight pyrolysis of the elements, and that plasma gas mixture has an impact on porosity as well as the oxidation state of the nickel.
Deposition of TiO2 Coatings: Comparison between High Velocity Suspension Flame Spraying (HVSFS), Atmospheric Plasma Spraying, and HVOF Spraying
Authors: Bolelli G. , Cannillo V. , Lusvarghi L. , Gadow R. , Killinger A. , Rauch J. , Bemporad E. , Sebastiani M. 
Published: December 2022

Abstract
In this study, a TiO2 (anatase) nanopowder suspension was processed by high velocity suspension flame spraying (HVSFS). The resulting coatings were characterized and compared to conventional HVOF and atmospheric plasma sprayed layers. It is shown that the HVSFS operating parameters can be adjusted to achieve dense titania with a near nanostructure and homogeneous distribution of anatase and rutile phases. These coatings have lower pore interconnectivity and higher wear resistance than the APS and HVOF layers. Alternatively, large unmelted agglomerates of anatase nanoparticles can be embedded in the coating, increasing the porosity and anatase content for enhanced photocatalytic efficiency.

Authors: Gulizia S. , Tiganis B. , Jahedi M.Z. , Wright N. , Gengenbach T. , MacRae C. 
Published: December 2022

Abstract
During cold spraying, small particles are propelled to supersonic speeds and adhere to the substrate on impact, forming a strong bond. This work examines the effect of process gas temperature on cold spray coatings produced from commercially pure (CP) titanium powders. Nitrogen gases at 400, 600, and 800 °C were used as the propellant and nitrogen and oxygen content in the titanium coating was examined. The findings suggest that at high gas temperatures, the oxygen and nitrogen in the commercially pure titanium deposits increases at the particle boundaries.

Published: December 2022

Abstract
This study investigates microstructural alterations in copper powder during cold spraying. A highly nonhomogeneous structure was observed with average strains of almost 50% close to the interface. Large strains and high strain rates resulted in significant grain refinement and the formation of sub 100-nm grains. Deformation occurred by slip and twinning, the latter promoted by impurities in the copper feedstock. Thin foils from the deposits were studied by TEM analysis and cross-sections of deformed particles were made and examined using FIB-SEM techniques.

Published: December 2022

Abstract
Repair of damaged ion vapor deposition aluminum (IVD-Al) on aircraft components generally requires the use of brush plating with hazardous materials including cadmium. This paper describes a cold spray process that uses aluminum transition metals to make such repairs. The aluminum layers are applied with a handheld cold spray gun and tested according to JTP-2003 requirements for corrosion resistant coatings on steel components.
The Effect of Ni Coating for Diamond on Metal-Diamond Composite Coatings by Cold Spray Deposition
Authors: Kim H.J. , Jung D.J. , Lee C. 
Published: December 2022

Abstract
This study assesses the effectiveness of nickel-coated diamond powder for producing metal-diamond composite coatings by cold spraying. The results of the investigation show that diamond fracturing was mitigated by the protective nickel coating. In general, the softer the metal matrix and the finer the diamond, the less fracturing that occurs and the greater the diamond fraction in the composite layer. It is also shown, however, that deposition efficiency and diamond fraction must be improved especially for diamond sizes of 50 μm and above.
Thermally Enhanced Kinetic Sprayed Titanium Coating: Microstructure and Property Improvement for Potential Applications
Authors: Bae G. , Kang K. , Na H. , Lee C. , Kim H.J. 
Published: December 2022

Abstract
In the present investigation, thermally enhanced kinetic spraying of titanium onto mild steel substrates is carried out in conjunction with powder preheating to obtain a dense coating using low-cost nitrogen as the process gas. Prior to this, a prototype model was developed for process optimization based on numerically approximated adhesion factors. The simulation results show that adiabatic shear instability accelerated by thermal energy and subsequent particle impact leads to the formation of an enhanced thermal boost-up zone that closely correlates with deposition behavior and coating properties. It is thus shown that the deposition efficiency of titanium can be more than 90% and porosity less than 1% when nitrogen gas is used for cold spraying.

Authors: Tang Caixian , Gulizia Stefan , Jahedi Mahnaz 
Published: December 2022

Abstract
This paper presents a way of processing cold-sprayed Ti-Al to produce titanium aluminum nitride coatings. These coatings are meant to serve as a durable protective layer on tools exposed to molten aluminum alloys. A Ti-Al powder mixture with a weight ratio of 70/30 was cold sprayed onto specially prepared substrates using nitrogen as a process and powder delivery gas. The resulting coatings were alloyed at different temperatures to obtain a stabilized Ti-Al intermetallic phase for further nitriding treatment. The nitriding process was carried out in an ammonia-nitrogen atmosphere at 900 °C. The final product had a web-shaped microstructure with the same thickness as the cold-sprayed Ti-Al. Test samples were placed in molten aluminum for 1200 hours without notable chemical reaction.
Microstructure and Biological Properties of Plasma Sprayed Novel Bioactive Coatings
Authors: Liu X.-Y. , Ding C.-X. 
Published: December 2022

Abstract
In this investigation, bioactive ceramic materials, including dicalcium silicate, titania, and zirconia, were deposited on titanium substrates by plasma spraying in order to determine their effect on the bioactivity of metal implants. Cell-seeding tests show that MG63 osteoblast-like cells grow and proliferate well on each of the coating materials. In the case of Ca2SiO4, the presence of silicon ions is thought to be the key to this behavior. In regard to TiO2 and ZrO2, the bioactivity is thought to result from the nanostructured surfaces and special surface compositions.

Published: December 2022

Abstract
In this study, suspension plasma spraying is used to deposit pseudo eutectic alumina-yttria stabilized zirconia as a potential thermal barrier coating. Process variables including feed rate, powder size, and plasma gas composition were altered to determine the influence of spray parameters on the formation of phases in the composite coating. The most significant variable was found to be the auxiliary gas. The gas influences the formation of phases primarily through its effect on in-flight particle velocity.

Authors: Robitaille F. , Yandouzi M. , Jodoin B. , Hind S. 
Published: December 2022

Abstract
The present work probes the deposition of metallic coatings on high fiber volume fraction carbon/epoxy polymer matrix composites using pulsed gas dynamic spraying. Well-consolidated and well-adhered coatings of zinc and copper were successfully applied and initial trials with higher melting point metals have been promising. Two key aspects of the technique are the low temperatures involved and the presence of embedded ductile particles in the substrate. The embedded particles promote adhesion and eliminate the need for surface preparation procedures along with associated risks. The hardness and porosity of the zinc coatings deposited on polymer matrix composites were found to be comparable to that of similar coatings on metallic substrates.

Abstract
In this study, plasma sprayed ceramic coatings with different amounts of SiC and MoSi2 particles dispersed in a ZrB2 matrix were produced and tested. The results show that MoSi2 addition in ZrB2-SiC samples improves high-temperature oxidation resistance without affecting mechanical properties. Demonstrative components were manufactured and tested in simulated operating conditions by means of a plasma wind tunnel. Preliminary results indicate that thermal sprayed ceramics are well suited for use in space re-entry vehicles.
