Authors: Öztürk Erkan
Published: March 2024

Aluminum-based Metal Matrix Composites (MMC) are commonly used in metal-cutting applications due to their better mechanical and physical properties, such as high strength, hardness, and low weight. Also, modern coating applications, especially multi-layer coated tools, have the cutting-edge potential for relieving the difficulties of machining MMCs to improve insert performances. Therefore, this study aimed to reveal the turning Al-4.5%Cu/TiB2/3p performance of the multi-layer coated cemented carbide insert with verified FEM and statistical approaches. Different coating materials, two and three of which were soft and hard, were appointed at different thicknesses and sequences in the design of experimentally calibrated simulations. The Grey Relation Analysis (GRA) was set to investigate the multi-layer coated insert performance for turning the MMC concerning the resultant cutting forces (FR) and maximum insert temperature (Tmax). The optimal multi-layered coating was found at levels 4-2-4-3-2 for the factors of coating materials: tungsten disulfide (WS2), molybdenum disulfide (MoS2), titanium nitride (TiN), aluminum oxide (Al2O3), and titanium carbo-nitride (TiCN), respectively. The contribution rates of each factor were significant concerning General Linear Model (GLM) at 47.13% and 24.43% for WS2 and Al2O3 coatings materials, respectively. In the future, multi-layered coatings can be a valuable solution for the difficulties of machining the MMCs.

Published: March 2024

This research proposes the application of an automatic tap device at the GBI Tanjung Pasir Church based on an Arduino Uno with an SR04 ultrasonic sensor. Water is the main need for living creatures, especially humans, and most people think that water is a natural resource that is unlimited in quantity. Currently, the operation of tap water is done manually; people often forget to turn off the tap water when the water is full, which causes the water to overflow in the bathtub and waste water in vain, indirectly results in wastage of water, and is very less efficient. An effective way to overcome this is to set the water level limit in the bathtub. In this thesis, an automatic faucet is used using an ultrasonic sensor, namely a sensor that will detect and release or turn off water automatically by activating the primary media using a solenoid valve. The results of this research show that the sensor on the faucet can automatically solve the problem of filling the bathtub when the water level is below a predetermined limit and will stop filling when it reaches the full limit. Having an automatic faucet makes it easier for users to fill and close water without having to monitor it while preventing wastage of water in the bathtub. With an automatic faucet, it is hoped that it can prevent wastage of water in the bathtub due to the user's negligence.

They are the main cause of many diseases in the world. Machine learning algorithms and techniques have been applied to various clinical trials to automate the analysis of large and complex data. Recently, many scientists have been using AI techniques to support life and experts to detect heart-related diseases in the care industry. Compared to the brain, which is the largest organ in the human body, the heart is the next largest organ. Blood is pumped and sent to all the organs of the body. Cardiovascular disease prediction plays an important role in clinical practice. Informative studies will be useful in anticipating more data that can help predict various diseases and focus on treatment. There is a lot of data about the patients that are seen each month. The stored data can be a source for predicting future disease outbreaks. Some methods of data mining and artificial intelligence are used to predict heart diseases, such as artificial neural networks (ANN), animation, etc. To reduce the number of people who die from heart disease, we need to do it quickly and have a way to detect it. Data mining techniques and artificial intelligence calculations help experts make better cancer predictions and diagnoses. The main goal of this research project is to use AI statistics to predict coronary heart disease in patients.

Authors: Rohit Bokade  , Dr. Namrata Gharat
Published: March 2024

This study focuses on the implementation of CNNs based on the Fast Fourier Transform (FFT) in medical images to study the performance boost compared to traditional neural networks. Using a Kaggle dataset of brain tumour imagery, we examine the effectiveness of FFT-based CNNs for the detection and classification of brain tumours. By leveraging the advantages of FFT, we aim to improve the efficiency and accuracy of CNNs in analyzing medical images. Our results demonstrate that FFT-based CNNs outperform traditional CNNs in terms of accuracy and computational efficiency. This performance boost is attributed to the inherent properties of FFT, which enable faster convolution operations and reduced complexity. In order to ensure a fair comparison between traditional CNNs and Fourier Transform-based convolutions, the forward pass for both methods was implemented from scratch using NumPy and SciPy libraries. By doing so, any optimization benefits gained by either technique through specific libraries or computation platforms are eliminated. This approach allows for a more accurate evaluation of the relative performance of each method in terms of inference time and accuracy, while also providing insights into potential areas for improvement and optimization.

Quantitative fusion of NLP, fMRI, and EEG data : A mathematical model for decoding semantic processing in the brain
Authors: Verma Vivek Kumar , Varma Gottumukkala K. Chaitanya , Varma Ch. Karthikeya , Shrotriya Anita , Dadheech Pankaj
Published: March 2024

This research introduces a novel mathematical model designed to integrate Natural Language Processing (NLP), functional Magnetic Resonance Imaging (fMRI), and Electroencephalography (EEG) data, aiming to decode the complex neural mechanisms of semantic processing in the human brain. By leveraging the complementary strengths of each modality—NLP’s linguistic analysis, fMRI’s spatial resolution, and EEG’s temporal precision—the model provides a groundbreaking approach to understanding how semantic information is processed across different brain regions and over time. The core of the proposed model is a dynamic, multi-layered framework that utilizes advanced statistical methods and machine learning algorithms. At its foundation, the model employs vector space representations from NLP to quantify semantic similarity and contextuality in language. These representations are then mapped onto neural activation patterns captured by fMRI and EEG, using a series of transformation matrices that are optimized through machine learning techniques. The model uniquely incorporates time-series analysis to account for the temporal dynamics of EEG data, while spatial patterns from fMRI data are analyzed through convolutional neural networks, ensuring a comprehensive integration of multimodal neuroimaging data. Key to proposed approach is the application of Bayesian inference methods to fuse these diverse data sources, allowing for the probabilistic modeling of semantic processing pathways in the brain. This enables the prediction of neural responses to linguistic stimuli with unprecedented accuracy and detail. Theoretical implications of our model suggest significant advances in understanding the neural basis of language comprehension, offering new insights into the dynamic interplay between linguistic structures and neural processes.

The goal of enacting the Regulation is to ensure greater transparency in the employment process in the public sector in FBiH. Access to the labor market should be guaranteed to all individuals within the territory of Bosnia and Herzegovina. In this regard, in order to ensure access to the labor market, it was necessary to establish the obligation of public advertising. For the first time, as of 2019, the Regulation explicitly stipulates the obligation of public enterprises to hire employees through public advertising. In terms of content, the Regulation has several shortcomings, but despite these, it represents a solid but insufficient legal framework. Namely, the Regulation does not correspond to the requirements of the labor market, and public sector employers find ways to bypass its application or act in contradiction to the Regulation's objectives. The major drawbacks of the Regulation are related to the need for double advertising in the application of the internship institute and the inconsistency with the fundamental principles of labor law, which consider the subject of labor law to be the "employee," while the Regulation centralizes the subject as the "workplace." Special attention is given to the recruitment of candidates in employment without the application of public advertising procedures, as well as the internal transfer of workers in public sector enterprises, which is a significant legal tool for all public sector enterprises. The paper also presents alternative institutes that employers use for candidate recruitment.

BAŞLICA ETKİN KRİPTO PARALARDA OYNAKLIK ANALİZİ
Authors: Erdem Lokman Salih , Atik Hayriye
Published: March 2024

Bitcoin'in 2009 yılında ortaya çıkmasıyla birlikte, birçok sektör üzerindeki etkileri gözlemlenmiştir. Ancak, kripto para piyasalarındaki yüksek volatilite ve merkezi bir kontrol olmaması, kripto paraların geleceği konusunda belirsizlik yaratmaktadır. Bu anlamda, finansal sektörlerin dinamik yapısı gereği diğer sektörlerden daha hızlı etkilendikleri doğal olarak kabul edilmektedir. Bu araştırmanın temel amacı, Bitcoin, Ethereum, Litecoin ve Ripple gibi dört kripto para biriminin yatırım aracı olarak potansiyelini değerlendirmektir. Bu amaç doğrultusunda, 1 Ocak 2018 - 1 Ocak 2023 tarihleri arasında, seçili kripto para birimlerinin getiri oranlarının volatilite özellikleri modellenmeye çalışılmıştır. Otoregresif koşullu değişen varyans modelleri (Autoregressive conditional heteroskedasticity - ARCH) analizi kullanılarak yapılan çalışmada, modelin volatilite tahmininin anlamlı sonuçlar vermesi üzerine VAR analizi ve Granger nedensellik ilişkileri eklenerek desteklenmiştir. Bu testlerin sonucunda kripto para birimlerinin risk profili incelenmiş ve gelecekteki fiyat hareketlerine ilişkin bir tahmin sağlanması amaçlanmıştır. Bu şekilde, kripto para birimlerinin potansiyel bir yatırım aracı olarak değerlendirilmesi konusunda tespitler yapılarak literatüre katkıda bulunulmuştur. Bu bağlamda, serilerde ARCH etkisi gözlemlenmiştir. Yapılan VAR ve Granger Nedensellik testleri sonucunda, Bitcoin'deki bir değişikliğin diğer altcoin'leri önemli ölçüde etkilediği ancak Ripple'da anlamlı bir etkinin olmadığı sonucuna varılmıştır.

Yeşil kahve dünya dış ticaretinde önemli bir ekonomik değere sahiptir. Ürün Karmaşıklık Endeksi'ne göre 104. en çok işlem gören ve 1024. en karmaşık üründür. 2021 yılında dünyada yaklaşık 10 milyon ton yeşil kahve üretimi, 7,8 milyon ton yeşil kahve ihracatı ve 7,5 milyon ton yeşil kahve ithalatı yapılmıştır. Bu çalışmada belirlenmiş araştırma soruları çerçevesinde 1986, 1995, 2000, 2010, 2013, 2018, 2020, 2021, 2022 yılları ihracat değerleri kullanılıp ağ analizi yapılarak dünya yeşil kahve ihracatında öncü ülkelerin ağ görselleri çıkartılmış ve elde edilen istatistiki değerler yorumlanmıştır. Buna göre ilk dönemlerde ticari bağlantı kuramayan ülkelerin sonraki dönemlerde bağlantı kurmaya başladıkları, ağların yoğunluklarının olumlu ekonomik dönemlerde giderek arttığı, özellikle salgın dönemi 2020 ve 2022 Rusya-Ukrayna savaşı dönemi gibi olumsuz ekonomik gelişmelerin olduğu yıllarda ise ağların yoğunluklarının azaldığı görülmüştür. Ayrıca dönemlere göre istatistiki değerlerde ve çekirdek ve çevre ülkelerde önemli değişimler tespit edilmiştir.
A Japanese translation of the Swedish Universities Scales of Personality

Published: March 2024

Background: The Swedish Universities Scales of Personality (SSP) is a personality measurement tool with a short test battery of high psychometric quality, previously not availiable in Japanese.

Methods: We translated the SSP into Japanese and administered it to 103 Japanese nationals. For 11 of the 13 SSP scales in the Japanese version of the SSP (SSP-J11), the Cronbach’s alpha ranged from 0.50 to 0.82 with good internal scale reliability.

Results: A principal factor analysis replicated the previous work by identifying the same three principal dimensions of Neuroticism, Aggression, and Extraversion factors.

Conclusion: The resulting three-factor SSP-J11 shows acceptable reliability and should provide informative insights about personality traits in research and clinical practice in a Japanese context.
Influence of contact interface design over the bond for-mation of 3D printed parts

Published: March 2024

Fused Filament Fabrication (FFF) is an additive manufacturing technology that uses molten thermoplastic materials forced through a nozzle to build parts layer-wise and enables the manufacturing single and multiple materials parts. The multi-material interface bond strength influences the resulting part integrity. The interface represents the physical boundary between materials, and its shape depends on the part’s design. However, the most common interface designs are based on a flat surface-to-surface contact. Thus, this paper aimed to investigate if the interface strength of polylactic acid-based (PLA) parts can be enhanced by designing new interface geometries with a sinusoidal and zig-zag pattern orientated in two directions. The resulting interfaces were tested mechanically and analyzed under the microscope to describe bond formation. The results show that interface shape orientation and overlap between mating bodies significantly influence the multi-material interface strength.
