Economic Returns to Reproducing Parents’ Field of Study
Authors: Birkelund Jesper Fels
Published: June 2023

Research on the influence of family background on college graduates’ earnings has not considered the importance of the match between parents’ and children’s field of study. Using a novel design based on within-family comparisons, I examine long-term earnings returns to reproducing parents’ field of study in Denmark. I find that individuals whose field of study matches that of their parents have earnings that are 2 percent higher than those of their siblings with college degrees in different fields, on average. Earnings returns to field inheritance are highest in the fields of law (9 percent), medicine (6 percent), and engineering (4 percent) and are driven mainly by income from self-employment. I find no direct evidence of nepotism as the earnings advantage does not arise from inheritance of parents’ firms or employment in parents’ occupational network. My findings indicate that, although a college degree generally equalizes family background differences in economic outcomes, there are additional payoffs to field inheritance, particularly in traditional fields characterized by a high degree of social closure and self-employment.
A Bayesian framework to account for misclassification error and uncertainty in the estimation of abortion incidence
Authors: Pejchinovska Marija , Alexander Monica
Published: June 2023

Obtaining reliable estimates of the incidence of induced abortion remains a significant challenge in abortion re- search. In recent years, one indirect, survey-based technique for measuring the incidence of induced abortion which has gained significant attention is the Confidante Method. The method has been employed in various legal and social contexts, however, its efficacy has not been uniformly established and many studies have found its success to be context-dependent. Greater focus has been placed recently on assessing the method’s key assumptions and quantifying and adjusting for biases that arise from violations in those assumptions. In this paper we propose a general statistical framework to conceptualize and quantify the impact of biases on measuring abortion incidence from surveys. Specifically, we define the relationship between observed and true abortion prevalence based on misclassification error related to the sensitivity and specificity of the survey instrument. We argue that this formulation leads naturally to a Bayesian modeling approach to estimate abortion prevalence. Such a modelling framework allows for different levels of uncertainty about the misclassification parameters to be incorporated in the modeling process, with that uncertainty being propagated through to the final estimates. We illustrate our framework and modelling approach on data from an application of the Confidante Method in Uganda in 2018, where we account for systematic differences in confidante abortion reports based on the self-reported abortion experiences of surveyed individuals.
Ambivalent Representation of India and its Politics in Hodges’s Travels in India
Authors: Joshi Dipak Raj
Published: June 2023

This paper analyzes ambivalent representation of India in William Hodges' Travels in India. The exploration of politics behind such representation can be interesting area to investigate. The writer has tried to portray the contradiction between ruins, antiquity, and depopulated habitation on the one hand; and modification, cultivation, and populated habitation, on the other. The horrendous act of sati has been depicted in a smart way as Hodges does not criticize Hindu tradition of self-immolation of wives for the death of their husbands; while the same custom was declared illegal and punishable later by English rulers in India during colonial time. Similarly, Hindu art and architecture has not been observed with the spectacle of Greek art which was considered model worldwide; rather it has been depicted as superb and guided by climate, culture, and geography of its own. Promod K. Nayar's notion of imperial sublime, Saree Makdisi's Romantic imperialism, and Julie Reiser's idea on writer as shared nervous system of circumstances have been used to strengthen the argument. The study concludes that the ambivalent representational stances created in Hodges' narrative try to justify English rule in India in the consolidation phase of the empire. Previous studies highlighted deserted landscape, customs, populations mainly focusing on the representation of Hindus, their art, architecture, the Muslim indolence resulting in devastation and ruin. This study, however, investigated the ambivalent representation and its politics behind the portrayal of the need of English presence in India for modification and habitation. Finally, this study also throws light on the gap for future research on the circumstances that led to the development of negative representation of the natives in colonial writing.
Identity Crisis in Desai’s the Inheritance of Loss
Authors: Ammai Narayan Prasad
Published: June 2023

The Inheritance of Loss by Kiran Desai is a novel set in 1980s which deals with the theme of identity crisis especially of the Judge, the Cook, Sai, Biju and Gyan who struggle with their identity within their own nation and foreign land and fail to maintain a strong position even within their own community due to the effect of modernization and globalization. These lower ranked people are victimized from elite class in search of identity. Desai depicts how minority group’s identity is excluded, back grounded and suppressed by the so-called majority group in literature through the discourse. She has also shown how world’s globalized context has exploited and dominated the working-class people’s identity and freedom.  This study focuses on exploring the complex web of relationships between identity and discourse as well as investigating the significant roles of literature in the construction of identity. The question that it arises is how identity is shaped by discourse in literature. In order to answer this question a wholesale analysis of the text is carried out in light of Tope Omoniyi’s Discourse and identity, James Paul Gee’s Critical Discourse Analysis and Stuart Hall’s Cultural Identity and Diaspora.

MATHEMATICAL MODEL OF THE REACTOR CONTROL OF THE ELECTROCHEMICAL TREATMENT OF INDUSTRIAL WASTEWATER
Authors:   National Technical University of Ukraine ", Mukhin V.E. ,   Igor Sikorsky Kyiv Polytechnic Institute"
Published: June 2023

Mathematical models of changes in the concentration of components under the action of an electric current have been developed. The problem of optimal control of current strength and costs is formulated. The main principles of optimal control calculation are developed. Methods of solving the problem of identification of model parameters with application to this problem of industrial wastewater treatment are considered. The problem of optimal control of current and consumption during the treatment of industrial wastewater with an electrochemical reactor of the ELION installation is considered. The mathematical formalization of this problem consists in the developed models of the dynamics of the concentration of components. First-order kinetics models are proposed, which describe the effect of current strength and flow rate on concentration. The model for two components takes into account the mutual influence of the concentrations of these components on each other and is non-linear. The study of the problem of optimal control based on the principle of Pontryagin’s maximum Optimal control is the selection and implementation of the best program of actions to achieve the desired state of the controlled object (based on its certain initial state) by influencing control parameters. Pontryagin's maximum principle serves as a starting point for solving many theoretical problems of optimal control and developing appropriate numerical methods. As a result, it is shown that the optimal control should be piecewise constant and accept in some sense minimal or maximum value. These theoretical studies are supported by a model example, which shows that piecemeal-continuous management is more acceptable than permanent. The obtained results make it possible to build quite effective methods of solving the problem of building optimal control, which allow implementation on a computer in real time.

Methodological aspects of assessing technical security speech information in designated premises
Authors:   State University of Telecommunications, Kryuchkova L. P.
Published: June 2023

Taking into account the continuous development of methods and means of interception of acoustic information, ensuring the technical protection of such information from leakage through technical channels remains an urgent task. The task of protection against leakage is to block all possible channels and neutralize means of interception. Quite often, in the process of discussions during meetings, information is expressed emotionally, with increased tension of the vocal cords (the so-called effect of forcing speech). At the same time, in addition to increasing the overall speech level, there is also a redistribution of energy within the spectrum, the energy maximum is shifted to the high-frequency region, which affects the contribution of frequency bands to overall intelligibility. Thus, there is an urgent need to develop a perfect method for assessing the security of speech information in dedicated premises. At the same time, the method should be independent of the structure and principles of operation of systems of technical protection of speech information with limited access, and take into account the possibilities of modern methods of digital processing of phonograms. The purpose of the publication is the formation of a methodical approach to the assessment of the technical security of speech information with forced sounding in a dedicated room against leakage through technical channels. The need to improve the methodology for assessing the technical security of speech information with forced sounding in designated premises is substantiated. A study of the difference between the spectrum of calm and forced speech was conducted, and the results of research on determining the width of the frequency spectrum of forced speech were given. In the course of research, it was determined that the spectrum of 70 Hz...10 kHz should be used during testing. The levels of the test acoustic signal, providing a confidence probability of 0,95, are 74 dB for quiet speech and 85 dB for forced speech. This approach can be used if it is necessary to assess the object’s security according to increased security requirements.

It is concluded that the capabilities of Google BigQuery can be extended with a number of third-party tools. For example, integrating it with Google Spreadsheets, Microsoft Excel, QlikView, BIME Analytics and Microsoft Power BI. It is established that the prospects of using Google BigQuery is to expand the ability to share this database with other software products and optimize query performance.
Research of the application of management technologies in computer networks
Authors:   State University of Telecommunications, Buchenko I. A.
Published: June 2023

Management in computer networks is carried out at different levels, depending on the needs of organizations, therefore this work considers the issue of using management technologies in a computer network. A computer network is defined. Control theory is described. An overview of available management methods was conducted. The principle of the negative feedback control system, which isused to maintain the process variable at a set value, is considered. Stages of the control cycle, types of control cycles, advantages of closed loop over open loop controllers, classification of general approaches in control theory are defined. Control theory deals with the control of dynamical systems in engineered processes and machines. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a desired state, while minimizing any delay, overshoot, or steady-state error and ensuring a level of control stability; often with the aim to achieve a degree of optimality. To do this, a controller with the requisite corrective behavior is required. This controller monitors the controlled process variable (PV), and compares it with the reference or set point (SP). The difference between actual and desired value of the process variable, called the error signal, or SP-PV error, is applied as feedback to generate a control action to bring the controlled process variable to the same value as the set point. Other aspects which are also studied are controllability and observability. Control theory is used in control system engineering to design automation that have revolutionized manufacturing, aircraft, communications and other industries, and created new fields such as robotics. To overcome the limitations of the open-loop controller, control theory introduces feedback. A closed-loop controller uses feedback to control states or outputs of a dynamical system. Its name comes from the information path in the system: process inputs have an effect on the process outputs, which is measured with sensors and processed by the controller; the result (the control signal) is «fed back» as input to the process, closing the loop.
Development of algorithms for assessing the state of information protection by means of network resources of IR communication networks
Authors:   State University of Telecommunications, Zakharzhevsʹkyy A. H.
Published: June 2023

The article describes one of the approaches to the creation of a system assessment of the state of information protection (ASIP), which can be used both for the IS assessment of a typical information system and for the analysis of a special system of enterprises in the telecommunications and other industries. Algorithms for assessing the state of information protection by means of network resources of the information and communication network have been developed. When developing an algorithm to describe the probabilistic characteristics of the truth of the hypothesis, we will use the concept of "confidence coefficient". A comprehensive evaluation of IS of the information system leads to the conclusion that the creation of an ASIP becomes a possible, justified, expedient and necessary step. In this case, one of the most important stages is the development of the user interaction algorithm and the system itself, which will ultimately represent some software. Interacting with the software interface, the user works with the mechanism for obtaining the results of the analytical evaluation, in which the data categories and DB are selected. In the process of coordinating the actions of the user and the ASIP to achieve various, independent goals and tasks, different interaction zones within the ASIP are determined by the needs and requirements for the implementation of these zones. There are two stages of defining areas of interaction between IS users and ASIP. The user interaction algorithm with ASIP consists of four stages, during which several requests from the system and responses from the user are produced. This description of the algorithm of interaction between the user and the system can be the foundation for developing the logic of ASIP work. At certain stages, the algorithm turns to the DB ASIP. In order for the report on the result of the IS assessment to always contain relevant recommendations for reducing or eliminating IT risks, the enterprise must keep the DB in an up-to-date state, and for this (in addition to introducing basic standards into it), new cyber security methods should be analyzed and added/corrected in industrial systems and digital production.

Authors: M. Wulandari  , N. Nofrizal  , Sulaiman S.A.S
Published: June 2023

A novel approach was taken using the bamboo root transformed into activated cellulose, implying dilute nitric acid as the agent activator. The activated bio-sorbent was applied for Iron(II) (Fe(II)) adsorption in batch mode. Then, biosorbent characterization was established using infrared spectroscopy and a scanning electron microscope (SEM). The effect of acid variation, iodine number, contact time, particle size, temperature, and concentration on the Fe(II) adsorption was determined in the batch method. The Freundlich and Langmuir isotherm were analyzed for determining the isotherm of adsorption. The Langmuir model of adsorption is the most suitable for illustrating Fe(II) adsorption. The optimum adsorption capacity occurred at the bio-sorbent particle size of 50 µm, contact time of 300 minutes, a temperature of 50˚C, a pH of 5, and 150 ppm. The bamboo roots have been applied to remove Fe(II) from wastewater, and the recovery% shows 100%. Comparative studies were analyzed with some bio-sorbents for further development. It is hoped that this novel alternative can be applied as bamboo is abundant in Indonesia and many countries in Asia regions.

In 2017, services at the Indonesian Institute of Sciences Center for Appropriate Technology Development, especially in the training registration administration section, had not been computerized so that data was piling up and difficult when the data was needed. Based on the existing problems, the approach taken is to analyze and design a training information system and implement it into an application form that is used to support the delivery and management of training and education programs in helping plan, develop and provide training to employees, communities, and other stakeholders. other interests. So it is necessary to develop an information system that can be personalized, and adaptive so that it can be adjusted for prospective training participants. The development method uses the PHP programming language, the CodeIgniter Framework with the concept of Model, View, Controller (MVC), modeling using the Unified Modeling Language (UML), MySQL database, and the Unified Process (UP) work method. The modules contained in the training information system include the Participant module, the Institution module, the Resource Person module, the Service User module, and the External Services module.

The paper proposes a novel method for counting apples in an orchard using unmanned aerial vehicles (UAVs), also known as drones. The authors acknowledge that traditional methods of counting apples are time-consuming and labor-intensive and therefore propose a more efficient and accurate solution using a group of drones equipped with high-resolution cameras. The proposed method involves using a convolutional neural network (CNN) called YOLOv5-v1 to detect and count the apples in the images captured by the drones. YOLOv5-v1 was trained using a dataset of annotated images of apples in different lighting conditions and orientations and was found to be highly accurate in identifying and counting apples in test images. The proposed method was tested on two different orchards and was highly accurate. Specifically, the results of the experimental studies show that the model accuracy was: i) in sunny weather – 92.11%, ii) in cloudy weather – 90.76%, and iii) in sunny weather, but with high shading – 82.69%. Such results indicate that under sunny and overcast weather conditions with a low level of shade, the proposed approach demonstrates high accuracy and reliability in real-time operation. At the same time, it should be noted that due to the presence of significant visual noise in the orchard, such as the covering of fruits by leaves and branches, the efficiency of the UAV group and the automated system, in general, cannot be 100% fulfilled in natural conditions, which can serve as a promising task for further of research. Overall, the proposed method of counting structural objects provides an efficient and accurate solution for counting apples in orchards, which could save time and resources for farmers. The use of UAVs and CNNs in agriculture is a promising area of research, and this paper presents a practical application of these technologies in fruit counting.

This paper addresses the task of time delay and direction of arrival estimation for a source of the wideband signal using two sensors with fixed displacement. The peculiarity of the task statement is that a limited time of signal observation is supposed and additive noise is assumed non-Gaussian with a heavy-tail distribution. This leads to a high probability of abnormal estimates for the conventional signal processing method based on cross-correlation. To decrease this probability, it is proposed to reformulate the task of cross-correlation processing to the task of similarity estimation between two data arrays. This allows using different similarity metrics, particularly those that have less sensitivity to outliers in data (impulse noise), and, thus, provide better robustness for non-Gaussian environments typical for several applications of time delay estimation. More than ten different similarity metrics are considered for the model of the symmetric α-stable distribution describing noise properties. It is shown that some metrics including cosine distance, Hellinger, and some others are able to provide sufficiently better accuracy of time delay estimation both in the sense of less RMSE of normal estimates and probability of abnormal estimates for typical values of α and a wide range of γ values for symmetric α-stable distribution.

Published: June 2023

The article uses the unified UML modeling language to visualize production elements. To show some of the advantages of the proposed approach, the main components of the production system are defined: technological machines, operators, materials, products and the production process. A class diagram is used to represent the components. Defined attributes and methods of each class: attributes and methods to each class that define its properties and behavior. The Machine class can have attributes such as machine ID and Destination, and methods such as start() and stop(). Relationships between classes are established: association, aggregation, and composition to represent relationships between classes. The Production Process class can have an aggregation relationship with the Machine class, indicating that the production process consists of multiple machines. This work contains UML diagrams and description tables that make it possible to structure the activity of the technological process in production. The technological process of manufacturing products is shown, which is presented in detail on the state diagram.

The preservation of the functional properties of the sewing product is regulated by technical regulatory documentation. The insufficient filling of the market with an assortment of clothes for women of large sizes is explained by the complexity of the geometry of the body surface, which is regulated by different approaches to the classification of sizes in the current anthropometric standards. The study of the dimensional variability of the range of large-sized figures in clusters of the main and additional dimensions of outerwear was carried out taking into account the synchronization of complete groups. Harmonization of the typology was carried out by cross-comparing the limitations of the size scale taking into account the type of figure M in the table of dimensions of the technical documentation. Body prototype M, height 168 cm, chest girth 110, 116 cm was chosen based on the frequency of occurrence in 10 models of women’s dresses. Graphical interpretation of absolute deviations characterizes the synchronicity of preservation of anthropometric commensurability at all levels of application of regulatory documentation. Numerical series of displacement values of 9 control measurements were formed for standardizing the basis of deviations for 4 regulatory documents based on the principle of combining in pairs. Confirmed synchronicity of preservation of anthropometric proportionality at all levels of application of regulatory documentation: figure-structure-product.
APPLYING DATA CLUSTERING METHODS FOR CREATING TARGETING USER GROUPS FOR REAL ESTATE

Published: June 2023

In this paper applied unsupervised clustering to a dataset examines the application of k-means clustering to create target user groups for a real estate platform. The goal is to segment the user base into meaningful groups to better understand their preferences and behaviors, and tailor marketing campaigns and product features to the needs of each group. The key step in the application of k-means clustering to real estate data is data preparation. Real estate data can be particularly messy and incomplete, and thus requires careful cleaning and normalization before clustering can be applied. Data preparation includes several key steps, such as removing irrelevant or redundant features, creating new features as feature scaling is also an important step in data preparation. K-means clustering is sensitive to the scale of the data, so features may need to be normalized to ensure that they are on the same scale, handling missing or erroneous data, and scaling or transforming features to ensure they are on the same scale. Dataset of 2000 customers interested in real estate with the various types of data was taken as a basis. Then the data was observed, investigated and based on results it was prepared for clustering by doing data cleaning as irrelevant data or empty data points may include features that do not significantly contribute to the clustering process, data normalization as it is necessary to ensure that all features are on the same scale, feature selection to determine most relevant features for clustering, feature encoding and dimensionality reduction which was achieved through principal component analysis (PCA). By carefully cleaning, normalizing, and selecting relevant features, clustering algorithms such as k-means were applied more effectively and target user groups were identified.
