Published: September 2023

Abstract— Objective: High physical function is a major achievement of healthy aging. Many older adults have low levels of exercise and physical activity, which may be due to a lack of motivation or access to proper exercise guidance tools. Providing a proper and enjoyable exercise guidance tool to older adults can be a good alternative to simply providing them conventional materials such as exercise training videos and encourage them to exercise regularly. Here, we demonstrate a novel home-based exercise guidance system named “Pei-Wo Drone” developed using a drone, a real, flyable three-dimensional (3D) object, to guide physical exercise or movement. The system provides real-time continuous sound feedback to notify the user if they are not following the drone correctly. Methods: The Pei-Wo Drone was developed and tested to ensure accuracy and precision in guiding two selective movements: "lateral arm reach" and "arm up and down" movements. Fifteen subjects (12 females, 3 males; aged 67.40±5.85 years) were recruited to evaluate their performance in following the guidance of the drone with interactive feedback. Results: The accuracy and precision of the system were impressive. Additionally, the results of this study showed that the subjects were able to follow the drone well. Conclusion: The Pei-Wo Drone, a newly developed drone guidance system, could encourage and guide older adults in proper exercise. Significance: Using a drone with real-time feedback to guide proper physical exercise or movement in older adults has a potential to enhance their physical well-being, while simultaneously providing a realistic and joyful experience reminiscent of playing with a toy at home.
Range Space and Similarity Transformation using Symbolic Mathematics in Python
Authors: Wisassakwichai Chainarong
Published: September 2023

 Linear systems involved in engineering and scientific calculations can be analyzed more easily using the mathematical tool of similarity transformation. However, understanding the numerous abstract linear algebra theorems associated with this transformation can be quite challenging. In this paper, we present computational methods for systematizing these theorems using SymPy (a symbolic mathematics library) in the Python programming language. The paper covers numerous theorems, including the basis of vector space, range space, null space, rank and nullity, eigenvalues, generalized eigenvectors, eigenspace, and diagonal-Jordan canonical form transformations. These theorems are transformed into abstract data models, which are then represented as programmatic objects using Object-Oriented Programming (OOP) for processing input and output data. The aim of this paper is to provide a more efficient and effective means of displaying and applying these theorems through the use of computers. A Python programming language module was eventually created from the developed programmatic objects. It can be used for programming both offline on PC and online through the web application "SymPy Live," producing satisfactory computational results compared to MATLAB, even when used on mobile devices. 
MEMORY CORRECTIONS AND DETECTION USING CRC’s WITH FSM MODELS ON FPGA
Authors: Goswami Mayank
Published: September 2023

Although it's crucial to transport data accurately between two sites since it's needed for some key applications, data transmission errors are surprisingly frequent. Error detection and correction often use the Cyclic Redundancy Check (CRC) approach. In this study, we present a new, hardware-optimized method for error detection and correction in the context of CRC-16, CRC-32, that operates at a comparatively lower power and higher frequency. The suggested method makes it feasible to locate single bit errors precisely and rectify them with the least amount of hardware. This technique saves memory because it doesn't need to look at tables. The effective application of this approach on FPGA is the main topic of this study.
Application of Neural Network Tools in Process Mining
Authors: Kovács László , Baksáné Varga Erika , Mileff Péter
Published: September 2023

Dominant current technologies in process mining use schema induction approaches based on graph and au- tomaton methods. The paper investigates the application of neural network approaches in schema induction focusing on three alternative architectures: MLP, CNN and LSTM networks. The proposed neural network models can be used to discover XOR, loop and parallel execution templates. In the case of loop detection, the performed test analyses show the dominance of CNN approach where the string is represented with a two- dimensional similarity matrix. The usability of the proposed approach is demonstrated with test examples.

Published: September 2023

Explainable models in machine learning are increas- ingly popular due to the interpretability-favoring architectural features that help human understanding and interpretation of the decisions made by the model. Although using this type of model – similarly to “robustification” – might degrade prediction accuracy, a better understanding of decisions can greatly aid in the root cause analysis of failures of complex models, like deep neural networks. In this work, we experimentally compare three self-explainable image classification models on two datasets – MNIST and BDD100K –, briefly describing their operation and highlighting their characteristics. We evaluate the backbone models to be able to observe the level of deterioration of the prediction accuracy due to the interpretable module introduced, if any. To improve one of the models studied, we propose modifications to the loss function for learning and suggest a framework for automatic assessment of interpretability by examining the linear separability of the prototypes obtained.
What Can We Learn from Small Data
Authors: Nyíri Tamás , Kiss Attila
Published: September 2023

Over the past decade, deep learning has profoundly transformed the landscape of science and technology, from refining advertising algorithms to pioneering self-driving vehicles. While advancements in computational capabilities have fueled this evolution, the consistent availability of high quality training data is less of a given. In this work, the authors aim to provide a bird’s eye view on topics pertaining to small data scenarios, that is scenarios in which a less than desirable quality and quantity of data is given for supervised learning. We provide an overview for a set of challenges, proposed solution and at the end tie it together by practical guidelines on which techniques are useful in specific real-world scenarios.
Decomposition Based Congestion Analysis of the Communication in B5G/6G TeraHertz High-Speed Networks
Authors: Talbi Djamila , Gál Zoltán
Published: September 2023

The New MAC mechanism plays a key role in achieving the needed requirements of the B5G/6G radio technology and helps to avoid high-speed frequency issues and limitations. With the help of the ns-3 simulator, we generated 42 different cases for the purpose of analyzing the impact of the network load on the overall effective transmission rate. Therefore, the use of the data-adaptive decomposition method the Empirical Mode Decomposition (EMD) on our non-stationary system benefits in the extraction of the important meaningful components. However, due to the highlighted direction dependency finding of EMD, Ensembled EMD (EEMD) being direction independent shows better performance on our data series. The extracted trend based on the proposed method matches the fitting curve, while the fitting curve parameters can be clusterized into 2 main clusters congested and non-congested cases of the radio channel throughput signal.

Authors: Fahim Abbas Alaa , Ahmed Kadum Samah
Published: September 2023

The current study was aimed to evaluate immune response induced by  Burkholdaria cepacia antigens to determine whether these antigens could be a useful immunogen for vaccine development against this bacteria. Four successive doses of OMP and killed antigen extracted from B. cepacia isolated from sputum of patients with lower respiratory tract infections were injected into rabbits using multisite injection protocol. We found that these antigens stimulate specific mucosal and systemic humoral immunoglobulin titers as well as to the significant increased (p≤ 0.05) in the total protein concentrations at serum and mucosal respiratory secretions in addition to the significant increase in the concentrations of IgG, IgA, IgM at rabbits sera. INF-γ concentrations were significant increased at serum and mucosal levels with stimulation of migration inhibition index of leukocytes. These immunogen induced positive skin test tuberculin type delayed hypersensitivity. Thus B. cepacia antigens were B and T cells dependent type, and could be a useful immunogen for vaccine development.

Background: Antibiotics are medicines that fight bacterial infections. If they are used probably, they can save lives. Still there is a growing problem of antibiotic resistance. It happens when bacteria undergo some mutation and become able to resist the effect of an antibiotic. Objectives: This cross sectional study was to determine the prevalence of antibiotics resistance among group of patients and to know the causes that lead to antibiotic resistance crisis to compare the results with previous studies concerning this subject in order to identify the risks of antibiotic resistance to offer some solutions (if any) that can minimize this problem at Iraqi hospitals. Methodology: This cross sectional study was conducted from May to October 2019. The sample was 128 patients (their specimens were cultured and antibiotic sensitivity was tested) especially toward a group of antibiotic. Results: At the end of this study the result showed that a higher group of resistance especially to penicillin group and a lower rate to azithromycin, another finding was the bacteria which infect (admitted in patients) were resistant to multiple drugs than those which infect (out patients). Conclusion: A high resistance to penicillin group, Staphylococcus aureus was found to be the most resistant microorganism as culture results showed.

Background: Male infertility affects 7% of males worldwide (i.e. 30 million of men). The diagnosis of the condition is based firstly on the semen analysis which can show various types of abnormalities. In Congo, data on male infertility are poor. This study aimed to determine the prevalence of male infertility in Brazzaville and to provide the profile of the semen parameters from a cohort of infertile men living at Brazzaville. Material and Methods: We studied semens of three hundred and forty-four (344) congolese men affected by infertility. The work was based on medical data to research medical history and the semen to performed the spermogram and spermocytogram in way to precise the sperm parameters, Results: The prevalence of male infertility found was 9% and the average age was 39 years old. Medical history highligts mostly the notion of chronic infection, varicoceles and surgery of the genital tract. The most identified sperm abnormalities were moderate asthenozoospermia followed by severe oligoasthenozoospermia and azoospermia. Conclusion: The prevalence shows that male infertility is not rare in Brazzaville. As the condition seemed to be related to the infectious, tumoral and professional causes, a complete investigation (based on sperm analysis, biochemical markers and genetic tests) is needed to clarify the etiologies.

Nutritional studies make little reference to essential amino acids to explain undernutrition in protein-energy malnutrition. This study aimed to carry out biochemical characterization and amino acid profiling of Detarium microcarpum and Adansonia digitata fruit pulps and Moringa oleifera leaf powder to show their contribution to protein balance. Biochemical analyses and amino acid profiles were carried out using standard methods and statistically analyzed using XLstat 2016 software. Results are expressed on a dry matter basis. Moringa powder had the highest ash, lipid and protein contents, at 10.72%, 8.75% and 23.85% respectively, compared with 4.14%, 1.99% and 4.19% for Detarium. Adansonia pulp had the lowest lipid and protein contents, at 1.36% and 1.83% respectively. In terms of total amino acids, Moringa powder had the highest content at 15.59%, while baobab pulp had the lowest at 2.18%. Essential amino acids for Moringa powder were higher and more balanced than for fruit. Histidine was absent in Adansonia digitata pulp, while methionine was absent in both Adansonia digitata and Detarium microcarpum pulps. Thus, blending the three resources could result in products with high nutritional value.

Published: September 2023

Culture and customs in Indonesia highly uphold the values ​​and norms that guide the implementation of leadership in each region. The application of cultural traits can be done using a paternalistic leadership style. Regional autonomy allows local governments to preserve local culture, including how to lead organizations by applying Eastern culture through paternalistic concepts. As part of the leadership of the local government, the Karangrejo Water Resources Office Technical Implementation Unit (UPTD SDA) of Tulungagung Regency applies paternalist leadership in its management. This research examines how the head of UPTD SDA Karangrejo implements the paternalistic leadership style. The research aims to identify and analyze the application of paternalist theory indicators in practice by the head of UPTD SDA Karangrejo. Some of the problems that occur in applying a paternalistic leadership style at UPTD SDA Karangrejo include the lack of opportunities for subordinates to develop creativity and imagination and the lack of motivation of subordinates and the lack of employees in carrying out daily tasks. This study uses qualitative research methods with descriptive methods. The data used is primary data. The research method used descriptive qualitative through interviews with UPTD SDA Karangrejo employees. Result 1). Paternalistic leadership is synonymous with the role of a fatherly leader. In this case, a leader is like a father to his children, namely the nature of protecting and nurturing his subordinates. 2). In making a decision, a leader must ask for advice from his employees or subordinates. 3). Leaders who are always right can lead to an authoritarian attitude even though sometimes the head of UPTD SDA Karangrejo wants to listen/accept suggestions from his employees. 4). The head of UPTD SDA Karangrejo rarely gives opportunities to his subordinates to develop creativity and imagination. 5). Head of UPTD SDA Karangrejo always obliges and demands his subordinates to obey the rules set. Paternalistic leadership runs effectively in the management of UPTD SDA Karangrejo, Tulungagung Regency.
THE EFFECTIVENESS OF COMPLETE SYSTEMATIC LAND REGISTRATION BASED ON REGULATION OF THE MINISTER OF AGRARIA AND SPATIAL PLANNING/HEAD OF THE NATIONAL LAND AGENCY NUMBER 6 OF 2018 FOR LEGAL LEGALITY OF LAND RIGHTS
Authors: Muhammad Taufiq  , Sri Astuti Agustina
Published: September 2023

Complete Systematic Land Registration (CSLR) is useful for the community to obtain the legal legality of land rights. The legal legality of land rights aims to create an orderly administration and legal order, which is urgent to avoid potential land disputes. Currently, it is found that not a few people from the community have an orderly administration of land ownership. This is evidenced by the total number of around 126 million land parcels in Indonesia, but still, around 100.14 million land parcels have been registered in the Complete Systematic Land Registration (CSLR) program, and 82.5 million certificates have been issued. The research aims to analyze the effectiveness of implementing the Complete Systematic Land Registration (CSLR) program based on the Regulation of the Minister of Agrarian Affairs and Spatial Planning/Head of the National Land Agency Number 6 of 2018 for the legality of land rights in Tenggong village, Rejotangan District, also described the constraints and government efforts to make the CSLR program successful in Rejotangan District. This study used a qualitative approach with data collection techniques in the form of direct observation and interviews in the field. Data sources were obtained from primary and secondary data with qualitative descriptive data analysis method. The research results show that the Complete Systematic Land Registration (CSLR) policy in the context of realizing orderly land administration in Tulungagung City has been going well where the policy standards and targets are already heading in the right direction, namely people from weak to middle economic groups, both those with fixed incomes and those with irregular incomes. In addition, the bureaucracy that impedes BPN's efforts and obstacles in the smooth running of CSLR is to be simplified so that the program can be implemented properly, quickly and efficiently to reach even more layers of society who benefit from the program.
Thick-walled coating in Gunn diode for measuring of electromagnetic radiation power in microwave range
Authors: Gretchikhin L.I. , Oleynik D.Yu.
Published: September 2023

In the introduction, the analysis of the physical basis for the operation of the semiconductor Gunn diode is carried out and the issues that should be resolved in substantiation of the basic physical principles of this diode operation are stated. At applied voltages of up to 0.6 V to a gallium arsenide or indium phosphide Gunn diode, free electrons appear in the conduction band of aluminum as a result of ionization of negative ions of gallium or indium atoms. At voltages from 0.6 to 2.0 V, free electrons appear in the aluminum conduction band as a result of ionization of negative ions of arsenic atoms, and at voltages from 0.6 to 3.0 V — phosphorus. The formation of negative gallium or indium ions is caused by electron capture directly from the aluminum base, while the formation of negative arsenic or phosphorus ions is mainly due to spontaneous electron transfer from the aluminum conduction band and from the negative gallium or indium ions. Electric current flows only over the surface of a gallium arsenide or indium phosphide crystal. The frequency of electric current oscillation is defined by the voltage applied to the Gunn diode and the thickness of the gallium arsenide or indium phosphide crystal. Determination of the power of microwave signals by the Gunn diode is carried out by applying a constant voltage between the cathode and the anode, which provides the frequency of current oscillation equal to the frequency of the measured microwave signal. The maximum radiation power in microwave wavelengths measured by the Gunn diode is determined by the equality of the electromagnetic wave perturbation energy and the electron affinity energy of gallium or indium atoms in the vicinity of the aluminum conduction band.

Published: September 2023

The article presents the dependence of the thickness of the anti-friction coating on the modes of coating. Application of an anti-friction coating on the surface of parts is based on the use of ultrasonic energy. The subject of research is the regression dependencies of the influence of the ultrasonic treatment mode on the thickness of the coating on the surface of the part. Four factors of the deposition process were identified: the radius of rounding of the top of the diamond tip, the transverse feed of the tool, the frequency of rotation of the sample, and the pressing force of the diamond tip. Based on the regression dependence, the influence of the coating thickness depending on the factors of this process was revealed.

Authors: Krioni N.K. , Mingazheva A.A. , Mingazhev A.D.
Published: September 2023

The article discusses the method of selecting ion irradiation doses for high-energy activation of the surface layer of alloy steel parts before nitriding. A criterion is proposed for optimizing the radiation dose of implanted ions from the strength limit of plate samples with a thickness commensurate with the thickness of the nitrided layer at implantation energies that ensure their end-to-end activation. The results of tests for rupture of plate samples with a through nitrided layer are presented. The results of comparative wear tests of samples made of alloy steels with nitrided layers used for the manufacture of machine parts operating under conditions of wear friction are presented. It is shown that the use of the method of selecting the dose of nitrogen ion irradiation with high-energy activation of the surface of samples made of alloy steels 40X and 40HN, allows to increase their wear resistance by approximately 1.3—1.4 times.

El objetivo es analizar si la conformación del comercio exterior de México (% de importaciones y % de exportaciones), entre los años 1946 a 2021, mostraron un patrón habitual, o bien, que a través del tiempo existe diferimiento. Los datos analizados provienen de fuentes oficiales, correspondientes a los primeros y últimos años completos (doce meses) de cada período presidencial. Se emplea metodología no paramétrica, conocida como la prueba de los signos. Los resultados indican que sí se presentó significancia que permite aseverar cambios importantes en la conformación comercial, sin embargo, los de mayor magnitud no están relacionados con épocas en que se hubieran esperado, como, por ejemplo, los años siguientes a la puesta en marcha del TLCAN o reciénteme el TMEC, inclusive durante el nuevo estilo anti neoliberal iniciado en 2018.
Analysis of the North Atlantic offshore energy flux from different reanalysis and hindcasts
Authors: Alday Matias , Raghavan Vaibhav , Lavidas George
Published: September 2023

To date there is a wide range of wave reanalysis and hindcasts available to the scientific and engineering community which are commonly used for different applications, including downscaling or the estimation of the wave energy resource (Morim et al., 2022). These long datasets have been created using different combinations of forcing fields, physical parameterizations, and numerical choices (like spatial and spectral resolution). All these elements have a direct effect on the accuracy of the wave models’ output (e.g., Alday et al., 2021) and thus, they are one of the main reasons for the differences between these products. In the present study we analyze the significant wave heights and peak periods characteristics from a selection of global datasets. We additionally include results from a hindcast created using the WAVEWATCH III model, with adjustments specially aimed to reduce uncertainties of the wave energy resource along the Atlantic coasts of Europe. Models’ output is compared with buoys and altimeter data from the latest ESA (European Space Agency) CCI Sea State V3 product. Preliminary validation of the hindcast we have generated for the North Atlantic already show an important bias reduction for wave heights in the 2.5 to 11.5 range compared to ERA5 wave product. Using the relevant wave parameters, we estimate the power density and quantify the differences between databases. Then, based on scatter diagrams obtained from the joint distributions of significant wave height and peak period, the differences in the power captured by wave energy converters (WEC) related to different wave data sources will be quantified (e.g., Babarit et al., 2011; Henriques et al., 2016).

Published: September 2023

An experimental investigation of the performance of a wave energy converter of wavestar type was conducted. A PTO system of downscale is difficult to directly apply in the model test because the experiment in the wave basin is based on Froude scaling. In case of the hydraulic PTO system, modelling of oil pressure and accumulator is more difficult in the wave basin test. To overcome the limitation of modelling of hydraulic PTO system, new model test technique was applied in this study. The model tests were performed in regular and white noise waves, and existed model test technique and new model test technique were compared in each other. From the results, characteristics of new model test technique were introduced.

Climate change is expected to have an impact on wind patterns, and therefore the generation of waves. Phase 6 of the Coupled Model Intercomparison Project (CMIP6), provides various realization of outputs integrated global coupled models for different centuries. Wind quality is a cornerstone for wave energy as it is the primary generation driver in any wave model. Therefore, proper quantification of wind wave interactions are key in the evaluation of future wave energy potential. In this study, a wave hindcast for the North-East Atlantic, using the WaveWatchIII model forced by CMIP6 winds is presented. The model uses a grid of 0.25° of spatial resolution, covering a longitude range of -21.0° to 10° (west to east) and a latitude range of 18° to 80° (south to north).The main objective of this work is to assess the quality of historical winds from all the CMIP6 wind data that are available under the first realization criteria (r1i1p1f1) at the time of this study. This leads to understanding limitations and proposing a selection method to choose the optimal wind dataset to force the wave model within the analyzed area.Thus, the optimal CMIP6 historical winds for the North-East Atlantic are used to create a 10 years hindcast(from 2003 to 2012). To further assess the suitability of the selected winds dataset for wave generation, results are compared with the ERA5 wave product. The available CMIP6 models show region-specific variations depending on the Regional Climate models used for their developments. The results show the impact of zonal and, meridional wind intensities, on wave characteristics in different regions over the domain.
