Published: May 2023

Automatic target classification or recognition is a critical capability in non-cooperative surveillance with radar in several defence and civilian applications. It is a well-established research field and numerous techniques exist for recognising targets, including miniature unmanned air systems or drones (i.e., small, mini, micro and nano platforms), from their radar signatures. These algorithms have notably benefited from advances in machine learning (e.g., deep neural networks) and are increasingly able to achieve remarkably high accuracy. Such classification results are often captured by standard, generic, object recognition metrics and originate from testing on simulated or real radar measurements of drones under high signal to noise ratios. Hence, it is difficult to assess and benchmark the performance of different classifiers under realistic operational conditions. In this paper, we first review the key challenges and considerations associated with the automatic classification of miniature drones from radar data. We then present a set of important performance measures, from an end-user perspective. These are relevant to typical drone surveillance system requirements and constraints. Selected examples from real radar observations are shown for illustration. We also outline here various emerging approaches and future directions that can produce more robust drone classifiers for radar.

Published: May 2023

Table grapes are characterized by high susceptibility to mold development during post-harvest, mostly due to Botrytis cinerea. Microwave application on ready-to-eat product can represent an alternative to antifungal treatment. With the aim of identifying the maximum energy that can be applied on grape without detrimental effects a Central Composite Design was developed testing the application of 10 combinations of treatment time (seconds) and microwave power (Watt). As a result, energies above 8000 kJ negatively affected the sensorial quality of fresh product, both in the presence and absence of B. cinerea inoculum (106 log CFU g-1). The physico-chemical parameters did not show significant differences, but two time/power combinations improved sensory quality of table grape, being selected for the subsequent packaging trial: 14 s/100 W and 80 s/100 W. Treatments were applied before or after packaging in polypropylene bags. At the end of storage period, 100 W applied for 80 seconds before packaging led to a better external appearance of the product than the other treatments, maintaining an intermediate level of mesophilic bacterial load and no significant differences in terms of nutritional quality. 80 seconds at 100 Watt combined with packaging can represent a valuable starting point for further experiments.

Authors: A Sathesh
Published: May 2023

Agriculture plays a key role in global economy. Tomato is India's third most prioritized crop after potato and onion, but it is the world's second most prioritized crop after potato. Worldwide, India ranks second in tomato production. However, Tomato crop is constantly threatened by different pest infections. The most significant pest infection that highly affects the tomato crop yield is Spodoptera Litura. Emerging from the family of Noctuidae with vigorous eating pattern, this insect primarily feed on leaves and fruits by leaving the entire crop completely destroyed. Monitoring the pest spread dynamics will reduce the probability of an outbreak. Early detection of pests can assist farmers in taking the required precautions to limit the spread of the infection. This paper provides a brief introduction to performs an assessment on the infection spread by Spodoptera Litura in the tomato plants. Here, the plants are classified as low, moderate and high pest infestation and further the severity of the damage is assessed by analyzing the number of S. Litura Larvae present in Tomato crop and also the percentage of pest infestation in tomato plants. The primary goal of this research study is to detect pests as early as possible and decline the usage of pesticides on the crops by taking early sustainable alternative measures.

при помощи метода конечных элементов решены задача на собственные значения и смешанная краевая задача для системы связанных дифференциальных уравнений в частных производных линейной теории электроупругости, описывающей колебания цилиндрического резонатора твердотельного волнового гироскопа с пьезоэлектрическими преобразователями. Для решения использовалась разработанная интегрированная система конечно-элементного анализа гравиинерциальных датчиков. Рассчитаны спектр собственных частот, энергия упругой деформации и диссипативные характеристики колеблющегося резонатора. Показана эволюция формы колебаний резонатора, возбуждаемого переменным синусоидальным напряжением заданной амплитудой на рабочей частоте резонатора, приложенным к двум противоположным пьезоэлементам, в разные моменты времени. Найдена временная зависимость электрических потенциалов на пьезоэлементах, уровень неустранимых фоновых переменных электрических потенциалов на приёмных пьезоэлементах, расположенных под углом 45 градусов к пьезоэлементам системы возбуждения. Проведена оценка минимально возможного времени выхода твердотельного волнового гироскопа на рабочий режим для выбранной конструктивной схемы при заданных параметрах возбуждения, обусловленного инерционностью резонатора гироскопа. Эти факторы должны учитываться при выборе конструкции резонатора и системы съёма и обработки сигнала с пьезоэлементов гироскопа

the eigenvalue problem and the mixed boundary value problem for the electroelasticity equations describing oscillations of the cylindrical resonator of a solid-state wave gyroscope with piezoelectric transducers was solved numerically. The developed integrated system of finite element analysis of gravity inertial sensors was used for the solution. The natural frequency spectrum, elastic strain energy, and dissipative characteristics of an oscillating resonator are calculated. The evolution of the oscillation form of a resonator excited by an alternating sinusoidal voltage of a given amplitude at the operating frequency of the resonator applied to two opposite piezoelectric elements at different times is shown. The spectrum of natural frequencies, the energy and dissipative characteristics of the oscillating resonator, the time dependence of the electric potential on the piezoelectric elements, the level of the background alternating voltage on the receiving piezoelements located at an angle of 45 degrees to the piezoelectric elements of the excitation system are determined. An estimate of the time it takes for a solid-state wave gyroscope to reach its operating mode was carried out. These factors should be taken into account when choosing the design of the resonator and the system for removing and processing the signal from the piezoelectric elements of the gyroscope

CROP GEOMETRY OPTIMIZATION FOR SUGARCANE-BASED INTERCROPPING IN A NEW PLANTING TECHNIQUE OF THE SUSTAINABLE SUGARCANE INITIATIVE IN INDIA
Authors: Saranraj T , Nagesweri R , Ajaykumar R , Tayade A.S.
Published: May 2023

Field experiments were carried out at the Sirugamani, Sugarcane Research Station of Tamil Nadu Agricultural University India in 2016-17 and 2017-18. The studies were designed to optimize crop geometry and identify a suitable intercrop for a novel planting technique of the sustainable sugarcane initiative. Sixteen treatment combinations (intercrops and crop geometries) were replicated three times in a strip plot design. Four crop geometries such as 150 x 60 cm single row planting, 150 x 60 cm double row planting, 180 x 60 cm single row planting, and 180 x 60 cm double row planting were assigned to the main plot. The subplot, on the other hand was earmarked for sugarcane-based intercropping, which included sole sugarcane, sugarcane + greengram, sugarcane +blackgram and sugarcane +sunnhemp. The intercrops were grown in an additive series, with three rows of sugarcane planted at 150 cm and four rows planted at 180 cm row spacing. The crop received an average of 730.3 mm of rain over the trial period. The soil at the research site was a well-drained clay loam with low, moderate, and high nitrogen, phosphorus, and potassium availability, respectively. A surface drip fertigation system was used to schedule the fertilizers and irrigation to the crops. By observing cane yield and yield-attributing characteristics at harvest, the impact of crop geometry and sugarcane intercropping in the sustainable sugarcane initiative method was investigated. In comparison to the majority of sugarcane-based intercropping, sugarcane+sunnhemp intercropping produced significantly more tillers at 120 days after planting i.e.150.60 × 103 and 88.88 × 103 tillers ha-1, respectively, in 2016-17 and 2017-18. Furthermore, growing sugarcane+sunnhemp intercropping yielded more millable canes (89.90× 103 and 1.43× 103) and cane equivalent yield (138.92 and 139.04 t ha-1) in 2016-17 and 2017-18. The 150×60 cm double row planting of sugarcane was found to be the best among the four crop geometries, yielding the highest cane equivalent yields of 132.85 and 152.56 tha-1 during plant I and plant II crops.
Keywords: Sustainable Sugarcane Initiative (SSI), Growth, Yield parameters, yield.

Axiological specifics of Russian gradational and additive conjunctions with the basic component da
Authors: Шереметьева Е.С.
Published: May 2023

В статье рассматриваются русские градационно-присоединительные союзы «да и», «да и то», «да еще» в аспекте их аксиологических возможностей. На иллюстративном материале показано, что во всех названных союзах заложена способность строить синтаксические конструкции с оценочным содержанием. Высказывается мысль, что выбор союза предопределяется желанием говорящего выразить оценку описываемых фактов, явлений, ситуаций. С другой стороны, союз диктует говорящему расстановку оценочных акцентов. В качестве итога в статье кратко сформулирована аксиологическая специфика каждого из описанных союзов.

The article deals with Russian gradational and additive conjunctions da i «да и», da i to «да и то», da iescho «да еще» in the aspect of their axiological capacities. The illustrative material shows that all the mentioned conjunctions have the capacity to make syntactic constructions with evaluative content. It is suggested that the choice of the conjunction is predetermined by the speaker's desire to express an estimation of the described facts, phenomena and situations. On the other hand, the conjunction dictates to the speaker the placement of evaluative accents. As a result, the article briefly formulates the axiological specifics of each of the described conjunctions.

Social Media as a Determinant of Students’ Dropout Rates in Secondary Schools in Kenya
Authors: Muthami Kaluki , Mwania Jonathan M. , Cheloti Selpher K.
Published: May 2023

Education is the natural right of every human being and is an integral part of every human life. The purpose of the study was to investigate the influence of social media on secondary school students’ dropout in public day secondary schools in Kenya. The article is an extract from a study done in public day secondary schools in Kitui central sub-county, Kitui County, Kenya. The study was guided by Bertalanffy’s Systems Theory. The study adopted descriptive survey research design. The study population was 25 schools and a sample size of 384 comprising of 22 principals, 22 form three class teachers and 340 form three students. Questionnaires for principals, class teachers and students were used to collect both quantitative and qualitative data. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 26. The corelation analysis results on principals’ responses showed a strong correlation (r=0.675. p=0.006) between social media and students’ dropout rate. A strong correlation (r =0.612, p =0.022) between social media and students’ dropout rates was also shown when the class teachers’ responses were analysed. However, corelation analysis of the students’ responses showed a weak correlation (r=0.214, p=0.041). The researcher therefore concluded that students drop out of school is influenced by social media. The study thus recommended that the community, teachers, and parents should educate students on good use of social media so as not to misuse it.
Prisión preventiva, una mirada desde la lógica jurídica
Authors: López Aquino Miguel Rolando , Torres Toledo Christian Hanesh
Published: May 2023

La exposición de motivos del presente ensayo tiene como objetivo identificar una visión epistemológica de la prueba conducente al dictamen de prisión preventiva para lo cual se requiere contar con estándares que respondan a la lógica jurídica, asi como también ponderar la libertad del individuo que no se ha comprobado fehacientemente el hecho punible que se le imputa.

Asumiendo que el mejor modelo para evaluar la prueba en el proceso judicial es el de la probabilidad lógica, es necesario reconocer que el razonamiento judicial en materia de hechos será siempre probabilístico y que ningún conjunto de prueba, por rico y completo que sea, permitirá certezas racionales.

Precisamente las normas de prueba ofrecen criterios para la fase de decisión, al no haber lugar a automatismos, la decisión sobre medidas cautelares personales en el proceso penal debe contener partes internas predefinidas con preceptiva explicación judicial y capítulos para el fumus comissi delicti y el periculum libertatis.

Published: May 2023

Phishing is the easiest method for gathering sensitive information from unwary people. Phishers seek to get private data including passwords, login information, and bank account details. Cyber security experts are actively seeking for trustworthy and effective ways to identify phishing websites. In order to distinguish between legal and phishing URLs, we used machine learning (ML) technology. In this research work using ML technology extraction and analysis of both types of URLs was performed. Extreme Gradient Boosting (XGBoost), Decision Tree (DT), Logistic Regression (LR), Random Forest (RF), and Support Vector Machine (SVM) were used to identify phishing websites. The goal was to identify phishing URLs and determine the most effective ML technique by comparing the accuracy rates of each algorithm. In this, proposed methodology two datasets were used. The accuracy of models was calculated on Phishtank and UCI dataset using kfold, feature selection and hyperparameter tuning method. Performance measures precision, recall and F1-score and Receiver Operating Characteristics (ROC) curve were calculated. RF provided an accuracy of 98.80% and 97.87% on the Phishtank dataset and UCI respectively. Highest precision, recall, F1-score value was 99% each and AUC-ROC value was 99.89% with Phishtank dataset. Validation with other researchers showed better results with proposed methodology. Therefore this methodology can be of help to identify phishing websites.

In this article, on the basis of the methodology developed earlier by the author for assessing the socio-economic development of the region, an improved methodology for assessing this region, taking into account the innovative component, is presented. According to the author, the development of the considered direction is designed to ensure the transition from the raw material model of the region's development to an innovative model, thereby ensuring its sustainable development. The presented indicators are selected using the methods of logical and correlation-regression analysis of regional innovation processes. The article step-by-step discusses the process of calculating each of the indicators proposed by the author. The adequacy of the application of this methodology with the set of indicators proposed by the author to assess the socio-economic development of the region was confirmed by a correlation analysis, which showed that the improved calculation method compares favorably with its previous innovative component and will reveal in the most detail the full potential of the region for the investor when choosing an investment region.

Authors: Yaw Osei , Agani Haadi
Published: May 2023

The purpose of this study was to develop an instrument for measuring students’ perception of teaching and learning variables in a Further Mathematics classroom with high psychometric properties of internal-consistency reliability and construct validity. A survey research design was used involving 318 students randomly selected from senior high schools. Enhancing Teaching and Learning Questionnaire (ETLQ) was used to solicit students’ responses on the issues they experienced during lessons for Further Mathematics. Principal component factor analysis with Promax as an oblique rotation and using a factor loading of 0.40 as a cut-off was further conducted on the data to record a more accurate representation of the relationship among the factors to establish the construct validity and the internal reliability of the instrument. The 26 items resulted in a four-factor solution produced based on the parallel analysis. The four factors together accounted for a total of 54.543% of the variance. The Cronbach’s alpha of the reduced 26 items is equal to 0.806. The subscales had acceptable internal consistency, as Cronbach’s alpha ranges from 0.696-0.893. The study reliability coefficient is high. The instrument will be useful for mathematics educators and researchers in Ghana and the world at large for measuring students’ perceptions of teaching and learning variables in a classroom. And the study recommends this instrument for use to measure the experiences of senior high school students in the classrooms.

Aspergillus Endocarditis in a prosthetic Valve following COVID-19 Infection
Authors: Vegiraju Sai Manogna
Published: May 2023

Endocarditis of a prosthetic valve is a known but rare occurrence. Fungal endocarditis is extremely rare. However, in the COVID-19 pandemic, there has been increasing recognition of fungal or yeast-related infections, often due to the combination of immune paresis, concurrent use of corticosteroids or underlying chronic conditions such as diabetes or neoplasms.
We present a patient with fulminating, invasive aspergillosis of a prosthetic aortic valve who presented with catastrophic cardiovascular failure needing intensive care management. Early recognition and prompt therapy is the cornerstone of success in such presentations with high mortality.

Introduction: Aneurysmal bone cyst is a rare, non-neoplastic lesion affecting the metaphysis of long bones and vertebrae, characterized by blood-filled spaces separated by fibrous septae.
Aims and objectives: In this study, we present a case of an aneurysmal bone cyst in a 7-year-old child with characteristic X-ray findings to increase awareness as early diagnosis and treatment can limit disability.
An aneurysmal bone cyst is a rare, benign neoplastic lesion affecting the metaphysis of long bones and vertebrae, characterized by blood-filled spaces separated by fibrous septae.[1] Diagnosis depends on typical features of magnetic resonance imaging, and confirmation by biopsy is essential before surgery is considered.  
We present an aneurysmal bone cyst in a 7-year-old child with characteristic X-ray findings. Diagnosis of ABC should be suspected in young patients presenting with limb pain or swelling, and pain disproportionate to the mechanism of injury could indicate pathologic fracture. Early detection of ABC is possible as an incidental finding by closely examining routine X-rays so that appropriate treatment can be instituted early and complications like pathologic fractures can be avoided. This case will help to increase awareness as early diagnosis and treatment can limit disability.
A SUSTAINABLE BUSINESS PROFIT THROUGH CUSTOMERS AND ITS IMPACTS ON THREE KEY BUSINESS DOMAINS: TECHNOLOGY, INNOVATION, AND SERVICE (TIS)
Authors: Lulaj Enkeleda
Published: May 2023

Purpose – This research examines and investigates the importance of sustainable business profit through customers and its impacts on three key business domains: technology-innovation-service (TIS). The main goal was to see what were the interrelationships of business-consumers and consumers-business analysis to have a sustainable profit based on the models: Innovation and Growth Teams (IGT), Innovative Customer Relationship Management (ICRM), Business-to-Consumer (B2C), Customer Service and Support (CSS), Customer Service Technology (CST), and Multidimensional Scaling model (MDS) or the factors (F1–F14). Were these factors important to businesses and which variables had the greatest impact on sustainable profit through consumer evaluation during purchase? Research methodology – This research was carried out on manufacturing, service, and distribution businesses (consumer-business analysis) and consumers (business-consumer analysis) in 200 businesses and consumers, through the completion of the online questionnaire and the meeting with the business managers, considering the same variables during the period (2019–2022). The data processing was done through (SPSS Statistics 23) using tests and econometric analysis (descriptive, factorial, reliability, multiple regression, and multidimensional scaling analysis) the model shows that all factors have great effects on sustainable business profit through consumers. Findings – However, it is suggested that of great importance for a sustainable business profit through customers are: the behavior of workers and staff, handling requests faster, business support before and after purchase, providing information applications (discount, usage, term of the expiration date, product content, payment methods as well as the provision of transport by the business for consumers. Research limitations – The limitations of this research are only a certain number of variables, years, and the number of businesses, but for other analyses and research, researchers can take a larger number of variables, businesses, and/or countries using the same models. Practical implications – Based on the above questions, it was confirmed that a (TIS) through models will make the profit even more stable by strengthening the position of businesses in the market against their competitors. So, in this case there are still practical implications in three key business domains (TIS) technology, innovation, and services. Therefore, businesses should pay attention to these findings to have a sustainable business profit. Originality/Value – Research related to sustainable profit through consumers considering three key business domains technology, innovations, and services (TIS) has not been analyzed earlier in terms of consumers as buyers and businesses as providers of products and services.
UNDERSTANDING ELECTRICITY PRICE EVOLUTION – DAY-AHEAD MARKET COMPETITIVENESS IN ROMANIA
Authors: Bâra Adela , Oprea Simona-Vasilica , Georgescu Irina Alexandra
Published: May 2023

The unexpected pandemic eruption in March 2020, the European efforts to diminish the gas house emissions, prolonged drought, higher inflation and the war in Ukraine clearly have had a strong impact on the electricity price. In this paper, we analyze the electricity prices on the Romanian Day-Ahead Market (DAM) along with other variables (inflation, consumption and traded volume of gas on DAM) over the last three and a half years in an attempt to understand its evolution and future trend in the economic and geopolitical context. Autoregressive Distributed Lag models are proposed to analyze the causality among variables on short- and long-term perspective, whereas Quantile Regression (QR) is proposed to enhance the results of the Ordinary Least Squares (OLS) regression. Furthermore, using market concentration metrics – Herfindahl-Hirschman Index (HHI), C1 and C3 ratio, we analyze the competitiveness on the Romanian DAM and correlate it with the electricity price evolution. The concentration indicators on this market reflect the degree of competition manifested between sellers and buyers respectively, their dynamics being able to influence the price level. The higher concentration on the sellers’ side (HHI = 1500) indicates a potential speculative behavior on this market that led to higher prices on DAM.
Obscuring Environment and X-Ray Variability of Compact Symmetric Objects Unveiled with XMM-Newton and NuSTAR

Published: May 2023

Compact symmetric objects (CSOs) show radio features such as jets, lobes, and hot spots, which are contained within their host galaxies, and likely represent a recent radio activity. A subpopulation of CSOs with high intrinsic X-ray column densities has been inferred from shallow, soft X-ray band exposures, and observed to cluster in the linear radio size versus 5 GHz radio power plane, which suggests that a dense circumnuclear medium may dramatically influence the growth of compact radio structures. Here, we report on the first detection of two CSOs, 2021+614 and J1511+0518, at energies above 10 keV with NuSTAR. We model the NuSTAR data jointly with the new XMM-Newton data of J1511+0518, and with the archival XMM-Newton data of 2021+614. A toroidal reprocessor model fits the data well and allows us to robustly confirm the X-ray properties of the CSO absorbers and continuum. In both sources, we find intrinsic X-ray absorbing column densities in excess of 1023 cm−2, hard photon indices of the primary emission, Γ ∼ 1.4–1.7, Fe Kα line emission, and variability of the intrinsic X-ray flux density on the timescale of years. The studied X-ray continua are dominated by the primary power-law emission at energies above 3 keV, and by the scattered component at energies below 3 keV. An additional soft X-ray component, modeled with a hot, collisionally ionized plasma with temperature kT ∼ 1 keV, is required by the XMM-Newton data in J1511+0518, which is corroborated by the tentative evidence for the extension in the archival Chandra image of the source.
