Published: March 2023

Concurrent optimization and prioritization of wire EDM parameters can improve resource allocations in material processing and should be effective. This study advances the integrated analytic (AHP)-Taguchi(T)-tournament-based-genetic algorithm (tGA) method to moderate the influence of erroneous resource allocation in parametric analysis decisions in wire electrical discharge machining. The structure builds on the AHP-T method’s platform obtained from the literature and develops it by including the tGA while processing the AZ91 magnesium alloy. The article evaluates the delta values for the average signal-to-noise ratios in the response table and deploys them to arrive at the winners in a league and consequently mutate the chromosomes for performance improvement. The scale of relative importance, consistency index, optimal parametric setting, delta values, and ranks are all established and coupled with the total value and maximum value evaluation at the selection crossover and mutation stages of the genetic algorithm. The results at the mutation, crossover, and selection stages of the tournament selection process showed total values of 124410, 96650, and 70564, respectively. At the selection stage, the maximum value to be the winner of the tournament is 28704. The crossover operation was accomplished after the 5th, 5th, and 6th bit for the first three pairs, respectively. For the selection and crossover operations, the maximum value is 28604 and 27944, respectively. The research clarifies which parameters are the best and worst during optimization using the AHP-T-tGA method.

It is difficult to improve the quality of friction stir welded joints of AA5052-H32 material because of scarce metrics on its concurrent optimization and prioritization. However, the objective of this article is to obtain optimal parametric values and identify important parameters using the Taguchi-Pareto method during the friction stir welding process of AA5052-H32 material. Then the ranks, delta values and optimal parameters are determined. The critical parameters identified for the friction stir welding process are the tool pin, rotational speed, welding speed and tool angle. When comparing the results of these parameters using the Taguchi method and Taguchi-Pareto method, the rotational speed retained its first position in both methods; the tool tilt angle gained the second position in the Taguchi-Pareto method from its third position when only the Taguchi method was considered. The welding speed became the third position in the Taguchi-Pareto method against the second position that it had in the Taguchi method. However, the tool pin profile retained its last position in both methods. Consequently, the rotational speed is the best parameter while the tool pin profile is the worst parameter. For the Taguchi-Pareto method, the optimal parametric setting is TPP2/TPP4RS1WS4TTA3. This is interpreted as cylindrical tapered or square tapered for the tool profile, 40 rpm of rotational speed, 75 mm/min of welding speed and 1.5° of tool tilt angle. The novelty of this study is the scope of analysis of the AA5052-H32 material that extends beyond the Taguchi method to the Taguchi-Pareto method where the concurrent optimization and prioritization of friction welding parameters are achieved.

Published: March 2023

Electric vehicles are a future transportation option that has the advantages of reducing air pollution and being environmentally friendly. Battery-based electric vehicles are still relatively new in Indonesia and have not received public attention like conventional oil-fueled vehicles. Electric vehicles such as electric cars have been socialized, but there are still many assumptions that electric cars are still not roadworthy because they are still in the development process. Presidential regulation number 55 of 2019 is expected to be the legal basis for boosting the development of electric vehicles in Indonesia. This study address to explore and identify the main impact factors of product change on the automotive industry in Indonesia. To identify this case, the model was built based on the Theory of Planned Behavior (TPB) which was expanded in the context of the adoption of electric vehicles. This study aims to identify what factors can affect product changes in the automotive industry. This model is formed by main constructs: individual behavior, subjective norms, and perceived behavior control, as well as three other factors identified from the literature review and interviews. Based on this research, it was found that three factors can have an impact on product changes in the automotive industry. These three factors are subjective norms, perceived risk, and logistical incentives. Apart from these three factors, other supporting factors are also expected to be able to develop the electric vehicle ecosystem in Indonesia.

Path Diagram of entrepreneurship in the COVID-19 era
Authors: García Lirios Cruz
Published: March 2023

- The process that goes from prospective decisions (oriented to risks of maximum profits with respect to minimum insurance benefits) to deliberate actions (oriented by avoidance of failures, based on the systematization of errors and successes) is addressed in the present work, aiming to specify a model for the study of Internet entrepreneurship. A non-experimental study was carried out with a non-probabilistic selection of 100 entrepreneurs. From a structural model, the reflective factor of the construct was found to be deliberate actions, but such findings are only applicable to the sample since the type of study, sampling, and statistical analysis suggest the contrast of the model in other scenarios would increase the percentage of the explained variance of its factors, that added to 57% in this case.
Particle motion and impact on flow field of pumping with suspended fibers
Authors: Zhang Qihua , Zhong Chengcheng , Xie Zhiang , Fang Zhou , Kang Shun , Zhang Weidong , Yan Zhaoxu
Published: March 2023

For uniform size and transparency, polypropylene fiber was chosen. When
using PIV, the velocity from suction to pressure side decreases almost
linearly between 1.0Q and 1.3Q. It does, however, fall from the suction
side and rise until it reaches the pressure surface at 0.7Q. From the
leading edge of the blade to the trailing edge, the spanwise velocity
nearly increases linearly. With increasing concentration, the velocity
increases slightly on the suction side while decreasing on the pressure
side, resulting in a small pressure rise. When the external
characteristic data of the pumping process is used, the pump exhibits a
small elevation of head. When the concentration is increased from 0.5%
to 1.0%, the efficiency gradually increases. The efficiency gradually
decreases as the concentration increases from 1.0% to 1.5%. To
investigate this discrepancy, a high-speed photographic system was used
to examine the distribution of fiber particles in the impeller’s
channels.

Authors: Shahmanesh Maryam , Malekhosseini Razieh , Niknam Taher , BagheriFard Karamollah , Yaghoubyan S.Hadi
Published: March 2023

The concept of a smart city is intertwined with a kind of great data
management, and through which, reaching optimal management. The data
transaction and the issue of communication between different equipment
are all defined on the IoT platform. The concept of IoT is a general
keyword referring to the widespread communication between equipment.
Nevertheless, the idea that metropolitan management can be implemented
with the targeted data processing faces challenges. On the other hand,
multicarrier energy management, in which various types of energy
generating structures like microgrids, smart grid, energy hub systems,
transportation sector, etc. converge together in an optimal energy
management program, is of great difficulty. Considering these
challenges, the processes of encryption, dispatching data, decryption
with the algorithm of the energy management plan should be intertwined
and all solved together as a general problem. The current paper has
presented a modified IoT architecture along with a multi-carrier energy
management application through integrating two distributed and
integrated management approaches. In the presented model, each
energy-generating agent in the first layer initially controls its own
internal supply and demand rate implementing distributed management, and
then in the second layer, each agent participates in a macro-competitive
market to achieve the optimal work point. Thus, in the presented model,
the data blockchain building protocol based on The Advanced Encryption
Standard (AES) in IOT platform is synchronized with the cloud-computing
center and an integrated energy and data security management program is
run, having the nature of the competitive market according to the block
building time by each agent. According to the results, in this approach,
while achieving the desired answer, the volume of data transaction and
consequently, the time to gain the final consensus may be considerably
reduced.

In this paper, convex continuous-time programming problem with inequality
type of constraints is considered. We derive new saddle point optimality
conditions and classical duality results such as weak and strong duality
properties, under additional regularity assumption. A fundamental tool,
employed in the derivation of the necessary saddle point optimality criteria
and strong duality result for convex continuous-time programming, is a new
version of a theorem of the alternative in infinite-dimensional spaces.
Classes of operators related to 2-isometric operators
Authors: Zuo Fei , Shen Junli , Chen Alatancang
Published: March 2023

We introduce the class of quasi-square-2-isometric operators on a complex separable Hilbert space. This class extends the class of 2-isometric operators due to Agler and Stankus. An operator T is said to be quasi-square-2-isometric if T*5T5 ? 2T*3T3 + T*T = 0. In this paper, we give operator matrix representation of quasi-square-2-isometric operator in order to obtain spectral properties of this operator. In particular, we show that the function ? is continuous on the class of all quasi-square-2-isometric operators. Under the hypothesis ?(T)?(??(T)) = ?, we also prove that if ET({?}) is the Riesz idempotent for an isolated point of the spectrum of quasi-square-2-isometric operator, then ET({?}) is self-adjoint.

Published: March 2023

Pupils’ Academic Performance is wanting in many primary schools in Uganda. The public primary schools in Ndorwa County, Kabale District- Uganda is one of the case scenarios in perspective. This research sought views of internal and connected stakeholders regarding parents’ attendance of school administration meetings, in support of pupils’ educational performances. The study was aimed at developing a parental involvement school partnership model. The researcher used cross sectional survey design supported to collect and analyze both qualitative and quantitative data. A sample size of 322 was derived from a population of 2000 using simple random and purposive sampling techniques. The research data was analyzed by way of frequencies, percentages, means and standard deviations. Qualitative data was analyzed using content and thematic analysis. The results show that students of highly involved family members in schools management meetings and functions significantly outperformed those with family members who were not involved based on scores of the PLE for class 7. Parents of low-come levels, and negative attitude towards their children’s education were the main challenge. To improve pupils’ academic performance, the research recommends that parents need to consider regular attendance of school meetings and functions. Also, the government of Uganda should create policies that ensure implementation of parental involvement welfares, building of schools, family, and community partnership programs to empower parents and support their Children’s learning. The practice of parents’ attendance in school meetings and functions in support of pupils’ studies needs to be in tandem with deliberations from the ministry of education policies, district education regulations and schools’ administration directives. Parents need to check what they aid to pupils with schools’ advice.

Authors: Belkacem Anes , Borsali Ahmed Riad
Published: March 2023

A new cost-effective mobile fronthaul architecture has been proposed by designing promising analog radio over fiber (ARoF) transmission system compliant with the next generation ultra-dense wavelength division multiplexing passive optical network (UDWDM-PON). It is conceived for standalone 5G/5G+ mobile communication systems driven by broadband multi-input multi-output (MIMO) millimeter wave data signals using two high spectral efficient modulations. The feasibility of the proposed system was firstly proven in terms of spectral tracing supported by theoretical analysis that disclosed good agreement. Furthermore, the obtained simulation results regarding the system performance evaluation after 22 km bidirectional optical fiber links were revealed high reliable characteristics including error-free transmissions at low receiver sensitivities, and measured power penalties less than 1 dB. In addition, the recovered eye diagrams maintained wide openings with high-quality patterns.
A flexible approach for biometric menagerie on user classification of keystroke data
Authors: Özbek Mehmet Erdal
Published: March 2023

Biometric systems aim to provide reliable authentication and verification of users. The behaviour of the users may alter the authentication performance when accessing these systems. Therefore, clustering users based on their actions is crucial. A biometric menagerie defines and labels user groups statistically according to their variability. However, determining groups is a fuzzy process and it may lead to inconsistencies. In this work, a novel and flexible approach is introduced based on the classification performance of the users data collected in a database without imposing any other restrictions. According to the performance measures obtained from the confusion matrix of the classification algorithms, users are ranked and then clustered. Additionally, the norm of a confusion matrix is offered augmenting the state-of-the-art performance metrics. The proposed scheme is evaluated using the behavioural biometrics modality on two benchmark keystroke databases. The performance results successfully illustrate the alternative way of grouping and identification of users sharing the same behaviour irrespective of the chosen classifiers or performance metrics.
Indicator of the influence of a geomagnetic storm on the transmission electric system
Authors: Mayer Daniel , Stork Milan
Published: March 2023

Magnetic storms are severe disorders in the Earth’s magnetosphere caused by enormous solar activity. The magnetic storm induces a quasi-stationary geomagnetic current (GIC) in the wires of the very high voltage (VHV) lines. These currents cause the current and thus thermal overload of the VHV part of the transmission lines, especially the transformers of the system. In the submitted article described by a device that indicates these effects of magnetic storms on the transmission system and allows it to carry out its safe operation. The indicator is located on the VHV wire of the bundle conductor. Using the Hall probe, it senses the magnetic field of the current in the line. With a digital frequency low-pas filter removes the ac component of the indicated current and information about its dc component, ie about the GIC, wireless transmission to the workplace of the system operator. This will then instruct the transmission system protective regime.

As in all fields, technological developments have started to be used in the field of medical diagnosis, and computer-aided diagnosis systems have started to assist physicians in their diagnosis. The success of computer-aided diagnosis methods depends on the method used; dataset, pre-processing, post-processing, etc. differ according to the processes. In this study, parameter optimization of support vector machines was performed with four different methods currently used in the literature to assist the physician in diagnosis. The success of each method was tested on two different Parkinson’s datasets and the results were compared within themselves and with the literature. According to the results obtained, the highest accuracy rates vary depending on the dataset and optimization method. While Improved Chaotic Particle Swarm Optimization achieved high success in the first dataset, Bat Algorithm achieved higher success in the other dataset. While the successful results obtained are better than some studies in the literature, they are at a level that can compete with some studies.
A Novel Non-Contact Measurement Method of Ball Screw Thread Profile Detection Based on Machine Vision
Authors: Miao Bing-yi , Wang Xian-cheng , Chen Jun-hua , Jiang Chu-hua , Qu Meng-yao
Published: March 2023

The transmission accuracy of the ball screw depends on the processing quality of the thread profile. Traditional detection method of thread profile is complicated and inefficient. When shooting the thread profile of the ball screw in the normal section, the camera axis must be tilted to the lead angle, and adjustment errors are easily introduced from both the front view and the top view. When shooting in the axial section, the spiral lines block each other, so the actual thread profile cannot be captured for detection. In order to solve the above problems, a thread profile detection method is proposed: the theoretical equation of the ball screw thread profile in the axial section is derived based on the theoretical thread profile in the normal section, and the theoretical equation of the thread profile projection curve in the axial section is solved based on helix analysis, and the differential equation between them is obtained; then, the theoretical correction value of the thread profile projection curve is obtained by Linear Search to find the boundary value; the actual thread profile in both axial section and normal section is finally obtained with the theoretical correction value, which can support accurate measurement and detection of the key parameters of the thread profile. Experiments show that the proposed method can effectively improve the accuracy of the ball screw thread profile detection.

The paper will give an overview of the basic leadership concepts of Oswald, evaluate his strengths and weaknesses and, finally, view these concepts from theological perspectives.
Emmanuel Levinas : Ideen I En Tant Qu’invitation au Travail1
Authors: López Sáenz Maria Carmen
Published: March 2023

This work starts by unfolding Levinas’ legacy from Bergson to phenomenology. Particularly, the article explores how Levinas deeply understood the meaning of Husserl’s transcendental idealism of Ideas I. He adheres to Husserl’s re(con)duction to the transcendental, understood by Levinas as the sense of existence overlooked by the naturalist ontology. Finally, it develops the Levinasian continuation of genetic phenomenology and its conclusion, that is, the irreducibility of ethical responsibility.
Anéantissement du Monde et Expérience Psychotique de Fin du Monde
Authors: De Gandt François
Published: March 2023

An attempt to bring Husserl’s phenomenology and psychopathology closer, based on the text of § 49 of the Ideen. What is an experience of annihilation of the world? How is a world undone? We will focus on the examples of the end of the world described in the stories of Gérard de Nerval and in the patients of Wolfgang Blankenburg.

Let K be a pure number field generated by a root α of a monic irreducible polynomial f (x)= xn
− m with m a rational integer and 3 ≤
n ≤ 9 an integer. In this paper, we calculate an integral basis of ℤ
K
, and we study the monogenity of K, extending former results to the case when m is not necessarily square-free. Collecting and completing the corresponding results in this more general case, our purpose is to provide a parallel to [Gaál, I.—Remete, L.: Power integral bases and monogenity of pure fields,J.Number Theory, 173 (2017), 129–146], where only square-free values of m were considered.

We are facing increasing concerns of citizens, local administrations and the European Union regarding the means of development of the rural area. This has become an important challenge for management teams regarding the development and innovation of the rural environment according to the trends, objectives and policies established at the European level and according to the changes and requirements arising as a result of the globalization process. The purpose of our research is to identify the particularities of financing the projects for the development of the rural space depending on the directions followed and the unexploited potential of the rural areas. Thus, financing and development opportunities are identified with the help of the funds provided by the European Union and the development directions established by it according to the changes and requirements that have appeared at the global level. The solutions found followed the aspects related to economic, social, agricultural problems, sustainable development and environmental protection, and the impact of the investment projects carried out since the beginning of the programming periods was followed.

In an increasingly challenging post-pandemic era, entrepreneurs from all over the world are forced to remodel their businesses so that they can meet the new needs of customers. The current paper aims to illustrate what is at the basis of the fundamental change in the way clients have formed their new expectations and what is the approach taken by organizations to remain relevant in the new dynamic environment. Digitalization, considered to be the term that encompasses several concepts regarding the transition to the online business environment and the automation of work processes, will be the main pillar of reference in terms of how organizations are forced to transform. The purpose and importance of Digitalization has become a topic of interest for all organizations, regardless of the activity sector in which they operate. The impact of the pandemic on the business environment led to an assiduous need to adapt to the new conditions. Questions were raised regarding the future of humanity in a climate that tends to be based on digital solutions. The impact of advanced technology in the business environment is seen as resilience in a climate with complex threats on different levels. This study considers demonstrating the importance of resilience within organizations as the engine that makes change happen in crisis situations. Research in the field claims that companies can gain resilience by preparing with complete IT systems, to respond quickly and efficiently in situations of crisis, shock or instability. Even more, there are theories that claim that the state of normality, as perceived by organizations, is not one of peace and stability, but of continuous change and adaptation.
ASPECTS OF NON-PARTICIPATION OF ADULTS IN VOCATIONAL EDUCATION AND TRAINING PROGRAMS
Authors:   Bucharest University of Economic Studies, Romania, PROFIROIU Marius Constantin
Published: March 2023

The contexts of the future labor market can be complex, but also uncertain. Thus, the acquisition of the most comprehensive competencies can be achieved by applying measures to renew educational practices. The article presents an analysis of participation in education and training for people aged between 25 and 34, respectively for people aged between 55 and 64. Reasons are also given for non-participation of adults in education and training programs. The analysis also presents the main obstacles that people in the two age groups (25-34 years, respectively 55-64 years) face when they want to attend education and training programs.

The general concept of European funds refers to the grant instruments allocated to the Member States of the European Union (EU), to reduce the economic and social development gaps between them. This article is based on the analysis of how to obtain European funds for different categories of entrepreneurs over a certain period. It also aims to inform about the significance of European funds and the ways in which farmers, researchers, NGOs, businesses, or young people can access non-reimbursable European funds. The aim was to develop the notion of European funds, the way in which these funds can be obtained, what are the stages of the process of accessing European funds, but also Romania's priorities financed by European funds, as well as their circuit from the beginning to the point where our country reaches the development process.
Replication of the Interpersonal Sunk Cost Effect
Authors: Bolinger Tristan C. , Ostermiller Mason A. , Martin Scott D.
Published: March 2023

Olivola (2018) postulated that the sunk cost fallacy, choosing a less preferred option simply because an original investment was already committed, would be facilitated by interpersonal factors. The prior work had compared sunk cost decisions made individually (intrapersonally) and those made on behalf of someone else (interpersonally) and found the relationship between type of investment and commitment of the sunk cost fallacy to be impacted by both intrapersonal and interpersonal influences. Our study sought to replicate Olivola’s original experimental methods and analyses but advanced his original research question with additional analytic investigation using factorial logistic regression. We found similar results to Olivola, however, we also discovered that committing the sunk cost fallacy was significantly more impacted by the price of the sunk cost rather than the person investing, χ2 (420, N = 423) = 209.41, p < .001, R 2 = .53, OR = 33.11, p < .001. This study expanded prior research findings on how individual investment decisions are influenced by others’ investments by contrasting this outcome with how the amount that is invested or given might be more important than the giver or the situation. This is an important distinction as future research seeks to find what influences people’s decisions for personal investments of money, time, etc.
