A simulation model of a simple supply chain consisting of a single distribution center and several points of sale was created. Initially, a new model was created with the name "Suplly Chain" and watches as units of model time. Next, a GIS (geographic information system) map was added to the diagram of the main object using the standard display settings. The distributor properties were defined and it marked the distribution point on the map. Next, retailers were added to the map: using the OpenStreetMap online server, to which AnyLogic sends addresses and receives coordinates and automatically arranges retailers. Manually added the properties of retailers. The next step was to create a model of trucks and their movement logic is set. To do this, a state diagram was used, with the help of which a diagram of the state of the logic of trucks was obtained. Using the New Agent Wizard, add a new agent type – order. It also changed the status chart to display order information. The created model was supplemented, where time was added for unloading and loading trucks from retailers. A basic simulation model of supply chains was built, and ideas for improving this model were considered.

This paper presents the use of different prediction algorithms in order to recognise the popularity of a song. That recognition gives features that are directly affecting popularity of a song. For this research, data from several hundreds of the most popular songs were used in combination with songs that often appear on different playlists from different musicians. The reason for this mixing of songs is done to ensure that the model works as efficiently as possible by comparing popular songs features with those of that are no longer trending. The processing of the collected data gave an excellent insight into the importance of certain factors on the popularity of a certain song. As a result of research, month of release, acoustics and tempo were represented as features that are mostly correlated with popularity. Through the processing and analysis of a large amount of data, four models were created using different algorithms. Algorithms that were used are Decision Tree, Nearest Neighbour Classifier, Random Forest and Support Vector Classifier algorithms. The best results were achieved by training the model with the Decision Tree algorithm and accuracy of 100%.

In today's world of technology and software shortages, recruiting is increasingly important. Businesses need new staff for start-up projects and are facing a problem they have so far ignored, namely the low level of knowledge and coding skills. In this work we consider what are the main mistakes in learning and writing code. Also, we investigate the problems in modern education and the training of future personnel.

The austenitic 316L steel (1.4401) is treated as an important stainless material that could be used to build antenna mounts and supports. Austenitic steel has a very good resistance to various kind of corrosion and also has good mechanical properties, i.e. tensile strength and elongation. The austenite steel is treated as rather correct weldable material although cracks in the joints are often present. The paper analyses the influence of various MAG welding parameters on creation good welds used in the stainless structures of antenna mounts and supports. Various tests verifying the mechanical properties of joint, including nondestructive tests, tensile strength, microscope observation and hardness test were carried out. A novelty in an article is the use various shielding gas mixtures with a very limited amount of nitrogen "below 1.5 % N2" in MAG welding.

The Internet of Things (IoT) is considered a new paradigm that aims to connect a large number of devices. IoT is increasingly present in domains such as healthcare, transport, agriculture, and other industrial branches. An increasing number of IoT devices, as well as the amount of data, leads to increased energy consumption and a negative impact on the environment. Therefore, researchers are focusing on the concept of Green IoT that aims to increase energy efficiency and create a safe environment. The focus of this paper is on energy-efficient techniques within green data centers. Also, the performance evaluation of data centers was performed in the GreenCloud simulator for the optimal load of data centers in terms of energy efficiency and sustainability.

This paper presents a novel realization of a compact dual-band bandstop filter, implemented with half-wavelength resonators in the E-plane. The filter implementation with half-wavelength resonators printed on the opposite sides of dielectric layer achieves a size reduction, while preserving the characteristics of the filter. The filter is designed in waveguide technology. The structure consists of a printed double-sided thin dielectric substrate to form an insert that is positioned in the E-plane of a standard rectangular waveguide WR-90. The proposed design achieves independent control of each single bandstop filter by simply adjusting the length of the half-wavelength resonators. The proposed dual-band bandstop waveguide filter is designed for the center frequencies of 9 GHz and 11 GHz.

In this paper we have conducted analysis of the outage probability (Pout) at the output of the receiver with selection combining (SC) in the channel affected by the presence of Beaulieu-Xie (BX) fading and Nakagami-m co-channel interference. The exact forms of the probability density function (PDF) and the cumulative distribution function (CDF) for the signal are derived and numerical results for the Pout in terms of normalized signal-to-interference ratio (SIR) for distinct values of fading parameters are discussed. In the second part of the paper, we propose a classification-based approach implemented in Weka to QoS level estimation leveraging Pout of the observed system as one of the inputs.

Metaverse is a massive virtual environment that moves in parallel with the original world. In developing Metaverse, collaboration and inter-discipline are needed so that in its development it can see from various points of view. One of the inter-disciplinary collaborations in the development of the metaverse is the ITB Metaverse Ganesha Campus project. In the initial stage of development, this project will focus on conducting digital twins on several iconic ITB buildings such as the East Hall, Plaza, and Main Gate. The project was developed using Unreal Engine 5 and exported to Android and PC platforms. However, based on the test results using various device specifications, showing the highest average FPS value only gets 4 FPS for Android and 10 FPS for PC. In addition, the existing APK installation file is quite large, which is 2 GB with raw files reaching more than 300 GB. For this reason, optimization is carried out by optimizing LOD and asset management to improve the performance and efficiency of the Metaverse. As a result, FPS increased up to 29 FPS for Android and 38 FPS for PC. While the APK file is compressed to 0.4 GB and the raw file becomes 9.3 GB.

One of the most fascinating and representative examples of digital transformation is the use of Digital Twins (DTs). The foundation of DT is the idea of a dynamic, virtual replica of an item or system that actually exists in the physical world. DT, which is supported and empowered by the Internet of Things (IoT) and Artificial Intelligence (AI), aids in both historical performance analysis and predictive analysis of physical assets, which eventually results in effective business operations. In other words, it accurately mimics real-world situations to foretell performance results, technical flaws, and future system enhancements. Therefore, utilizing DTs can assist organizations and industries in creating and implementing more sustainable products, processes, and workflows. This paper presents an attempt to unlock the sustainability potential of DT technology.

We successfully developed a lanthanum (La)-doped Pb (Zr, Ti)O3(PLZT) based ferroelectric capacitor (FC) using a new electrode material of bismuth (Bi) doped SrRuO3 (B-SRO) aiming at reduction of energy consumption of ferroelectric random access memory (FeRAM) by suppressing the leakage current of its FC. Our employed B-SRO layer is effective for suppressing the leakage current due to reducing atomic interdiffusions of Iridium and lead between IrOx top electrode (TE) and PLZT. Space charge limited conduction (SCLC) is dominant in the leakage current of the FC with B-SRO, while defect assisted conduction possibly includes in the leakage current of FC without B-SRO in addition with the SCLC. Switchable polarization, depending on the B-SRO thickness, has largest value for 1.0-1.5 nm thick B-SRO. Excellent imprint and switching (fatigue) endurances is proven on the FC with 1 nm thick B-SRO.
