Experimental Validation of Power Output and Efficiency for an Oscillating Water Column (OWC)
Authors: Ertürk Bozkurtoğlu Şafak Nur
Published: May 2024

With the global energy demand escalating and concerns over the environmental impact of fossil fuels, there's a pressing need for cleaner, sustainable alternatives. This study highlights the potential contribution of wave energy to the power needs of coastal structures in the context of renewable energy. The research evaluates the power output and efficiency for an Oscillating Water Column (OWC) system that can be integrated into coastal structures to meet part of their power needs. Findings from both theoretical calculations and a 1:10 scale model experiment are presented. The mechanical power output and efficiency of the system for a full-scale prototype were calculated for deep water conditions with a wave height of 3m. The water surface oscillation inside the chamber is assumed to reflect the oscillation occurring outside the chamber. The maximum average mechanical power output for the full-scale prototype, corresponding to a wavelength of 22.5 m, was determined to be 64.8 kW, achieving a mechanical efficiency of 64.4%.
The overall efficiency of the system is calculated as 55% by assuming the generator efficiency to be 85%, resulting in an average power output of approximately 55 kW. A 1:10 scale model of the OWC system with a Wells turbine was constructed and tested in a tank for deep water conditions. Froude similarity and Keulegan-Carpenter similarity were used, ensuring a seamless transition from the model to the prototype. The OWC model was subjected to controlled heaving motion with a period of T=1.2 s. The power generated by the OWC model illuminated four integrated 3.4V LEDs on the Wells turbine, which were used to measure the power output produced. The power output of the model was measured to be a minimum of 0.12 W for a rotational speed of 107 rpm, which corresponds to a power output of 12 kW for the scaled-up prototype. This system has the potential for further enhancement by incorporating multiple OWCs into coastal structures exposed to wave action. Such development could facilitate meeting the power requirements of coastal structures, thereby contributing to the promotion of both renewable energy generation and a sustainable environment. Future research will focus on optimizing OWC chamber sizes for specific sites and refining the model to better capture water surface oscillation dynamics.

The paper describes the current state of Internet banking in India and discusses its implications for the Indian banking industry. Particularly, it seeks to examine the impact of Internet banking on banks’ performance and risk. Using information drawn from the survey of 85 scheduled commercial bank’s websites, during the period of June 2007, the results show that nearly 57 percent of the Indian commercial banks are providing transactional Internet banking services. The univariate analysis indicates that Internet banks are larger banks and have better operating efficiency ratios and profitability as compared to non-Internet banks. Internet banks rely more heavily on core deposits for funding than non-Internet banks do. However, the multiple regression results reveal that the profitability and offering of Internet banking does not have any significant association, on the other hand, Internet banking has a significant and negative association with risk profile of the banks. This research work was undertaken to ascertain the impact of Internet banking in Indian banks and evaluation of its effectiveness in the banking system. To put this study on a unique out look I’ve designed together information while personal questionnaires interaction was paid purely to areas of customers and cashiers of Indian bank and review of related literatures to the main themes and sub themes. It was ascertained that Internet banking has helped the banks to attain goals and objectives. KEYWORDS:internet banking, information technology,electronic transfers

POWER FACTOR IMPROVEMENT BY USING STATIC VARIABLE COMPENSATOR
Authors:   DEPARTMENT OF ELECTRICAL ENGINEERING GOVERNMENT COLLEGE OF ENGINEERING, JALGAON, SS PROF DHAMSE
Published: May 2024

This project aims to improve the power factor of transmission lines using a static variable compensator. Traditional methods using large rotating parts were inefficient and prone to damage. Static VAR Compensation under FACTS employs Thyristor Switched Capacitors (TSC) controlled by a programmed microcontroller. This system compensates the power factor using thyristor-switched capacitors, where the zero voltage and zero current pulses are fed to a microcontroller. Previously, power factor compensation relied on large machines like synchronous condensers or switched capacitor banks. Shunt capacitive compensation, where a shunt capacitor is connected to draw current leading the source voltage, improves the power factor for inductive loads. The program controls opto-isolators interfaced with SCRs to achieve near-unity power factor. The project can be further enhanced with thyristor-controlled triggering for precise power factor correction.
“Decoding Bird Species Diversity through Image Analysis
Authors:   Zeal college of Engineering and Research, Pune, India, Bhandawale Swapnil
Published: May 2024

Bird species diversity plays an integral role in maintaining ecosystem equilibrium and serves as a significant indicator of environmental health. However, the meticulous monitoring and cataloging of bird species within specific regions pose considerable challenges, often requiring extensive time and expertise from ornithologists. In today's rapidly advancing technological landscape, the integration of image analysis and machine learning presents a promising avenue to streamline bird species identification and diversity assessment processes. Nonetheless, the increasing rarity of certain bird species presents a formidable obstacle, complicating their classification. Birds encountered across diverse environments present varying sizes, shapes, colors, and orientations, adding complexity to accurate identification via image analysis. Moreover, image- based classification exhibits more pronounced variations compared to audio classification, although human perception of birds through images remains intuitively comprehensible. Leveraging the deep convolutional neural network (DCNN) algorithm, images undergo conversion into grayscale format to generate autographs using TensorFlow, resulting in the creation of multiple comparison nodes. Subsequently, these nodes undergo comparison with the testing dataset, generating a score sheet for analysis. Interpretation of this score sheet facilitates the prediction of the target bird species based on the highest score achieved. Experimental analysis conducted on datasets such as Caltech-UCSD Birds demonstrates the algorithm's efficacy, with bird identification accuracy ranging between 80% and 90%.

Abstract
Anemia is a hematological disorder, and a large number in the developing world are affected with significant morbidity and mortality. Among them, most depend on traditional medicine to strengthen the hematopoietic action. The availability, low cost, and minor side effects are thought to be associated with this high selection rate of traditional medicine. The Pterocarpus marsupium is a medicinal plant native to Sri Lanka, India, and Nepal. In which the different components are used by traditional medical practitioners in treating different disease conditions, specifically, latex in enhancing hemoglobin production in anemic patients.  However, the scientific evidence for using the Pterocarpus marsupium latex as an anti-anemic agent is minimal. Therefore, this study is planned to evaluate its anti-anemic effect, erythropoietin (EPO)-like effect, toxicity, phytochemical composition, and bioactive ingredients. Consequently, we aim to apply in vitro and in vivo assays to investigate the toxicity and favorable anti-anemic and other hematopoietic potentials of the plant latex using normal human cell cultures, rat-derived hematopoietic stem cell cultures, zebrafish embryos, and phenyl hydrazine-induced anemic rats with identification of bioactive ingredients that might mediate such potentials. If we discover a similar action of EPO in this plant latex, it would be beneficial in the way of treating anemia-associated disease conditions such as chronic renal failure, myelodysplasia, rheumatoid arthritis, HIV, and cancer as a replacement for recombinant human EPO (rhEPO). This will be beneficial in the way of reducing the high cost of rhEPO treatment as well. Finally, an attempt to discover a therapeutic agent for anemia from a safe, natural source will considerably contribute to traditional medicine/herbalism due to the crucial role of traditional medicine in the prophylaxis or therapy of hematological diseases in Sri Lanka.

The Ecology of English Loanwords in Chinese: A Case Study of Cement
Authors: Mo Ruifeng , Xiao Hao-Zhang
Published: May 2024

From an ecolinguistic perspective, this study focuses on five English loanwords in Chinese related to the field of cement, as defined in the Modern Chinese Dictionary. The research quantitatively examines the ecological dynamics of these loanwords using two indicators: lexical niche breadth and overlap. The goal is to uncover the evolutionary mechanism governing their adaptation. The findings show: (1) The emergence of English loanwords is intricately linked to specific social environments. As new concepts and items are introduced from abroad, the masses initially make new loanwords, which are later standardized by authoritative bodies. (2) The vitality of loanwords correlates with their niche breadth. The competition among lexical variants is influenced by niche overlap. The loanwords for cement, ranked by vitality in descending order, are ShuiNi (3.221), YangHui (2.350), ShuiMenTing (1.385), HongMaoNi (1.202), and ShiMinTu (0.879). (3) The endangerment of loanwords results from a combination of external (social environment) and internal (language system) factors. Intense competition arises due to the presence of multiple synonyms for the same entity, and localization challenges occur when the loanwords do not precisely fit the entity. Among the five loanwords for cement, the first two exhibit higher vitality and continue to develop sustainably, while the last three show lower vitality and are gradually becoming endangered. As these loanwords undergo continuous evolution, a lexical ecocontinuum emerges: extinct in the wild—ShiMinTu; critically endangered—HongMaoNi; endangered—ShuiMenTing; vulnerable—YangHui; least concerned—ShuiNi.

Oral communication is one of the most important skills of communication among individuals with each other. It refers to communication between the students and their teachers through the spoken language, which includes a group of distinctive words, phrases, and sentences which are associated with specific meanings. However, there are many barriers that affect this communication. Therefore, this study addresses some of the barriers of anxiety when communicating using the English language in which it constitutes a major problem for EFL students and hinders their goals in learning the English language. This study aims to investigate the EFL students’ perceptions towards the effect of anxiety on their oral communication in various Saudi universities. Moreover, it explores some strategies that may help EFL students to overcome this problem. The research instrument used in this study was a questionnaire that was modified for the purposes of the study. The questionnaire consisted of 20 items divided into two parts. Furthermore, 102 EFL students participated in this study. The results showed that EFL students suffer from anxiety while speaking English, whether in a discussion class with the teacher or when presenting a presentation. The participants also agreed with most of the strategies stated in the survey. Based on the findings, recommendations and suggestions for further research are provided.
Ecological Discourse Analysis of the English Translations of Song of Peach Blossom Land from the Perspective of Transitivity
Authors: He Haoqi , Zhang Weiwei
Published: May 2024

In light of the degradation of the ecological environment, linguists have integrated ecology with linguistics, giving rise to the emergence of ecolinguistics. Ecological Discourse Analysis (EDA), as a form of discourse analysis, serves as an analytical approach within the field of ecolinguistics. Considering that Systemic Functional Linguistics (SFL) can be applied in analyzing ecological discourses and acknowledging the existing differences between Chinese and English languages, this paper conducts an EDA on both Chinese and English translations of “Song of Peach Blossom Land” from a transitivity perspective, aiming to present disparities in translation skills and accuracy. The results reveal that material processes account for over 50% of processes in all three texts and are consistently observed throughout them. Natural ecology is portrayed through depictions of the peach blossom land’s scenery; social ecology is presented by describing the social background and friendly relationship between the fisherman and villagers; spiritual ecology is embodied by his decision to leave his hometown but ultimately return to this land again. Furthermore, disparities in translation skills and accuracy exist within the Chinese-English translation.

Published: May 2024

Integrating information communication technologies in education goes with many digital learning applications. Blended learning Approach (BLA) has been an important strategy that facilitates students’ learning. This study investigated stakeholders’ perceptions on the adoption of a blended learning approach (BLA) in Tanzanian secondary schools. Specifically, the study identifies stakeholders’ perception on the adoption of BLA in secondary schools, examines the learning environments that support the adoption of BLA in Tanzanian secondary schools and assesses the extent to which the BLA is used in secondary schools. Data were collected via self-administered questionnaire and interviews; the response of 620 participants were analysed. The results showed that participants adequately had confident perception towards the adoption of BLA on students’ learning; further, in the studied schools, learning environments were perceived to be supportive in the adoptions of BLA based on available devices and services; this will, later, positively facilitate the adoption and influence the increase of level of BLA usage among teachers and students. However, poor infrastructure, lack of institutional support and insufficient hardware and software facilities impinged the use of BLA. In conclusion, BLA is well perceived; thus, the resolution to the challenges would promote its application in the classroom.
Key elements, processes and research gaps in city learning as an innovation ecosystem: A scoping review.
Authors: Banerjee Pradipta , Petersen Sobah Abbas
Published: May 2024

Learning in cities with the support of Information and Communication Technologies has been a point of interest for researchers. The main objective of this study is to understand city learning, or learning in cities, where cities are considered learning and innovation ecosystems. This study explores how learning in cities is supported by existing frameworks for city transformations and identifies the key elements and processes for city learning as an innovation ecosystem. The study defines city learning as a process involving citizens, institutions, and communities and considers the city to be a system that can learn and innovate. The study conducts a scoping review of relevant literature and a qualitative analysis of the key characteristics of the frameworks, such as how they view the city, how they address learning, what interactions they focus on, and how they use Information and Communication Technology. The study identifies the main concepts, the key elements and processes in city learning and the current research gaps. The key elements and interactions are then described with reference to a conceptual model of the city ecosystem, and the elements are mapped with required processes to drive city learning. The findings from this study can help ascertain how a city can learn as an innovation ecosystem and can be beneficial for achieving twin transitions of the city and lifelong learning

Published: May 2024

The purpose of the article is to understand the current state of both the technology and the implementation of emotion recognition in the educational environment. The goal is to obtain detailed information about the current state of emotion recognition technology and how its practical use is being carried out in educational settings. In this line, it examines the proposals from publications over the last 10 years on the advancement of technology for emotion recognition in education. A total of 1,347 studies were obtained and 43 were included in the review for analysis and discussion. The article demonstrates how the number of studies has increased in recent years, with a higher frequency in online learning. Furthermore, according to the Technological Readiness Level, despite the growing interest in emotion recognition in the educational environment, its implementation is still far from becoming a reality. Most of the research has been conducted from a theoretical perspective and none of them has been fully developed and implemented in the classroom. In addition, many of the studies analysed have not tested the validity of their findings.
