Utilising the "New York City Taxi Trip Duration" dataset from Kaggle, we designed an experiment focusing on three critical analytical tasks: aggregation, sorting, and filtering. Our objective was to quantify the performance improvements offered by IMC, as facilitated by Apache Spark, against conventional SQL queries executed on a disk-based system. The findings reveal that IMC consistently outperforms disk-based processing in execution time, with significant reductions observed across all tasks. Specifically, the aggregation task highlighted the stark contrast in data retrieval speed, demonstrating IMC's superior efficiency with a completion time of 47.3 seconds, compared to 138.7 seconds for disk-based processing. Similar disparities were noted in sorting and filtering tasks, further accentuating IMC's performance advantage. Resource utilisation analysis, focusing on CPU and RAM consumption, indicated higher demands associated with IMC, underscoring the trade-off between enhanced speed and increased resource usage. The investigation provides a nuanced understanding of the practical implications of adopting IMC for big data analytics, especially considering the resource constraints of home computing environments. By juxtaposing theoretical advantages with empirical data, this paper contributes to the ongoing discourse on optimising data processing methodologies in the era of big data, offering insights into the balance between computational efficiency and resource management.

This study examined effects of credit reference system on the right to privacy of customers of financial institutions. The credit reference system being a medium for the exchange of personal information of customers of financial institutions taking part therein; aims at facilitating credit market efficiency and stability. The right to privacy on other hand tries to keep to the minimum the intrusion to private domain of persons, customers of financial institutions being one of them. This article critically examined how these two seemingly conflicting interests have been compromised under the Ethiopian laws. A doctrinal research approach was employed in the analysis of the Ethiopian laws on the right to privacy and laws governing the credit reference system . The review of literature and analysis of legal instruments of both national and international character have been used to substantiate the arguments set forth in this work.This work concluded that even though violation of the right to privacy of the customers of financial institutions can be justified on the ground of voluntary relinquishment such rights; the Ethiopian credit reference system still needs reconsideration in light of principles recognized internationally for the protection of the right to privacy of persons. This work recommends for the revision of the Ethiopian credit reference system for better protection of the right to privacy of customers of financial institutions.

Lung cancer is a major contributor to cancer-related mortality globally, and timely identification is essential for enhancing patient prognosis. Recently, deep learning methods, specifically Convolutional Neural Networks (CNN), have demonstrated encouraging outcomes in image-based medical diagnosis. The paper suggests utilising a CNN-based method to diagnose lung cancer from a healthcare image dataset, with a specific focus on histopathological image data. The proposed CNN approach utilises the natural hierarchical characteristics found in healthcare imagery to autonomously acquire distinctive features that indicate lung cancer. Transfer learning from extensive image datasets and improving models that have been trained are used to tackle the limitations of limited healthcare image datasets successfully. The CNN model utilising the VGG-19 architecture is developed and tested on a comprehensive dataset of lung cancer patients. Following extensive testing and evaluation, the model demonstrates high accuracy as well as precision and recall in diagnosing lung cancer using medical imaging. Interpretability techniques are utilised to get insights into the model's decision-making process, hence increasing its transparency and therapeutic relevance. The proposed CNN-based technology has the potential to help radiologists and clinicians discover and diagnose lung cancer earlier, leading to better patient care and treatment outcomes.

The study was conducted at Dangila district, Amhara region, Ethiopia. The concept of linkage in this study is communication and work together to develop and disseminate improved agricultural technologies to farmers. Researchers and development agents are the main actors in the process of technology release and transfer and their achievement depends on strong linkages with each other. The lack of integration and coordination between agricultural research and extension has resulted in confusion as to who should undertake on-farm verifications and pre-extension trials before making technologies directly available to farmers. The objective of this study was to identify and describe the factors that influence farmers’ participation on the technology demonstration. Simple random and purposive sampling techniques were used for selecting respondents and study area for this study. The data collection tools also included interview schedules and check lists. The data were analyzed through binary logistic regression model. The binary logistic regression model analysis result indicated that, Sex, education, extension advisory service and land ownership factors were significantly influence the farmers’ participation on the technology demonstration. In general perspective role of linkages in the process of technology transfer in Ethiopia were weak. The major reasons were non/little involvement of farmers in the research system, top-down approach, poor use of linkage mechanisms and strategies.
Weeds constitute a serious problem to wheat crops and cause a great loss to the yield. Manual weeding is labor-intensive and time-consuming. Chemical weed control has a negative impact on both the environment and humans. To overcome these problems, an engine-operated weeder was designed and developed at Asella Agricultural Engineering Research Center (AAERC). The developed weeder was designed on the basis of agronomic and machine parameters. The developed prototype weeder consists of the mainframe, weeder blade, ground wheel, and power transmission system. The rated engine speed of 2800 rpm was reduced to 46 rpm of the ground wheels by using bevel gear, chain, and sprocket mechanism in three stages. The overall dimension of prototype weeder was 1650 mm in length, 800 mm in width and 1050 mm in height. The total production cost of the engine-operated weeder was 11,409.92 ETB. This paper is focused on machine design analysis and fabrication of prototype. Performance evaluation of propototype would be addressed in the next coming paper.
Classification tasks are difficult and challenging in the bioinformatics field, that used to predict or diagnose patients at an early stage of disease by utilizing DNA microarray technology. However, crucial characteristics of DNA microarray technology are a large number of features and small sample sizes, which means the technology confronts a "dimensional curse" in its classification tasks because of the high computational execution needed and the discovery of biomarkers difficult. To reduce the dimensionality of features to find the significant features that can employ feature selection algorithms and not affect the performance of classification tasks. Feature selection helps decrease computational time by removing irrelevant and redundant features from the data. The study aims to briefly survey popular feature selection methods for classifying DNA microarray technology, such as filters, wrappers, embedded, and hybrid approaches. Furthermore, this study describes the steps of the feature selection process used to accomplish classification tasks and their relationships to other components such as datasets, cross-validation, and classifier algorithms. In the case study, we chose four different methods of feature selection on two-DNA microarray datasets to evaluate and discuss their performances, namely classification accuracy, stability, and the subset size of selected features.

The most commonly used sampling techniques in research are probability and nonprobability methods. While probability sampling is based on the principle of random selection of participants in a particular study, non-random selection is the basis of probability sampling. The random and non-random classifications appear to have some potential flaws and are insufficient to represent all sampling procedures involving human participants. Similarly, most authors believe that they use random sampling techniques, although in reality, they do not use true random sampling. Therefore, the objective of this paper is to highlight that sampling techniques can be characterized as true-random, quasi-random, or nonrandom, rather than merely random and nonrandom. Attempts have been made to show how inadequate random and non-random sampling methods are, the characteristics of true-random, quasi-random, and nonrandom sampling procedures, and when each sampling procedure is appropriate. Since each unit of the population is randomly selected and the chance of selecting the unit is equal, a real random sample is used to estimate the characteristics of the population directly from the sample. With quasi-random sampling, it is not possible to directly estimate population characteristics, but only indirectly. However, population characteristics cannot be directly or indirectly estimated by using non-random sampling techniques.

This study explores all viable methods and techniques for the production of a responsive humanoid robot which would be both practically feasible and economically efficient. In the past few decades, scientists have been highly interested in the development of life-like humanoid robots. Some of these robots were used mostly in transporting heavy objects of accessing regions that were unreachable by humans. Between 1980’s and the 1990’s, engineers and scientists shifted their interest to the development of humanoid robots. These types of robots were able to stand, walk, and even pick up objects with mechanical hands. The introduction of humanoid robots greatly increased the interests of ordinary people in humanoid robots in particular. However, with the interest in these robots came the issue of communication. Majority of these robot have little or no recognizable facial features and would have to communicate with an external user by the use of audible sounds or visual symbols. This issue brought up the idea of creating robots that have recognizable facial features and are capable of carrying a conversation with humans. This project will develop a responsive and controllable humanoid robot head which would be capable of recreating basic movements of the human neck (such as rotate and pitch) as well as some basic and widely recognizable human facial expressions. This project focuses on developing a cost efficient, and practical process of creating animatronic robotic protype which will serve as a springboard for researcher, students, academia, and robot developers. The study further conducts a biomechanical analysis of the human head with specific emphasis on facial features including skeletal and muscular tissue structure to assist readers to learn and replicate the process. Above all, the project will enable researchers, scholars, students, and robot making companies to produce an animatronic humanoid robot head which can recreate basic human facial expressions that are easily recognizable to the average human such as happiness, anger, fear, sadness etc. to assist smooth communication, and business transaction. Also, the robot would be capable of recreating basic human neck and head movements like tilting of the head upwards and downwards and rotating of the head from side to side to follow human instructions.

In today's highly interconnected world, network security has become a critical aspect of protecting organizations from cyber-attacks. The increasing sophistication of attackers and their ability to exploit software and firmware vulnerabilities pose significant dangers to the security of networks. However, many organizations often neglect the essential steps required to secure their networks, leading to an increased risk of security breaches. In this research article, we aim to address this issue by investigating network security concepts, potential dangers, and practical defense strategies. We begin by exploring the different types of cyber-attacks and their sources, highlighting the various ways attackers exploit network vulnerabilities. We also examine the reasons why organizations often overlook network security and the consequences of not prioritizing it. To better understand the complexity of network security, we categorize the different security concerns using the CIA (confidentiality, integrity, and availability) triangle. This approach allows us to identify the various areas of vulnerability and their potential impact on network security. Next, we focus on the most crucial basic concepts and steps involved in various network security operations. We outline the best practices and practical approaches organizations can take to improve their network security, including implementing security policies and procedures, using encryption and authentication methods, and conducting regular security assessments. By highlighting the importance of network security and providing practical guidance on how organizations can defend against cyber-attacks, we hope to raise awareness and help prevent security breaches.
