The highlands of the central, south-eastern, and North West parts of the country are the main wheat-growing areas, however, there was no/little experience of wheat production in the lowland. Poor irrigation management that results in either excessive or inadequate water application can significantly reduce the potential for profitability. Increasing irrigation efficiency by applying improved water management strategies could be the prime objective for sustainable irrigated agriculture. In Jimma zone, even though there are a plenty of available natural resources such as land, water and suitable agro-ecology, there were some water deficit because of their location (physical nature) in the gorges and not suitable for surface irrigation and demand sophisticated irrigation technology. In this study different literatures were seen in addition to site observation at different irrigated wheat cluster farming to identify the different challenges and opportunities of irrigated wheat production. The major challenges for the production of irrigated wheat in Jimma zone were limited study on the suitability of the specific area of land for irrigated wheat farming, limited agricultural inputs, in adequate and low performance of small scale irrigation schemes, disease and pest problem, lack of market access, lack of financial support for irrigated wheat, and low quality of wheat products. Availability of water resources and irrigable land and high demand of wheat from the consumer side are among the opportunities that encourage farmers and other stakeholders to involve in the irrigated wheat production in Jimma Zone. The quality of irrigated wheat has to get an attention from the producer side.","PeriodicalId":15681,"journal":{"name":"Journal of Engineering and Applied Sciences","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80254316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ion exchange resin is used to purify water during the operation of 3 MW TRIGA Mark II research reactor in Bangladesh, when the decontamination efficiency is insufficient to maintain the required primary coolant quality. Five spent ion exchange resin samples and eleven liquid samples from exhausted coolant of 3 MW TRIGA Mark II research reactor were analyzed by using HPGe detector having 40% relative efficiency and 1.8 keV resolution coupled with computer-based MCA. Two radionuclides 54 Mn, 60 Co have been recognized in the spent ion-exchange resin and three radionuclides such as 137 Cs, 60 Co, and 65 Zn have been identified in the liquid radio wastes samples. The specific activity concentrations of these nuclides and the Inhalation dose for the corresponding nuclide for different body parts such as bladder, Bone surface, Brain, Breast, Stomach, Kidneys, Liver, Red Marrow, lungs, Skin and Thyroid for public are also evaluated according to the ICRP 68. Rad Toolbox software was used for the assessment. The maximum inhalation dose is originated from 137 Cs and lung is found to be the maximum radiation sensitive organ, received maximum dose of 53.5 m Sv from 60 Co (1332 keV). The experiment results would be helpful to develop a policy for radioactive waste management that produced during the operation and maintenance of a research reactor.","PeriodicalId":15681,"journal":{"name":"Journal of Engineering and Applied Sciences","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85476794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The machine’s smallest unit is the link, which is akin to a cell in the human body. Robotics is built on the foundation of machines. A pair is established by the combination of links which leads to the construction of linkage. A mechanical linkage is a collection of bodies that are connected to control forces and movement. The combination of linkage (also known as Mechanism) generates Machine. The robot’s kinematics equations are used in robotics, video games and animation. Inverse kinematics is the mathematical process of determining variable joint parameters necessary to place an object at the end of a kinematic chain in a specific position and orientation with respect to the start of the chain, such as robot manipulator or skeleton of an animated character. The role of Forward and Inverse Kinematics in a 2R Robotic Arm are studied with successful demonstrations. Forward Kinematics of a 2R Robotic Arm using Matlab and Python confirming similar results are exhibited (Figure 8 and Figure 9). Matlab illustrated 2D Path Tracing for 2R Robotic Arm with Inverse Kinematics. Finally, inverse kinematics of 2R Robotic Arm in Matlab using fuzzy logic is modelled successfully. Thus, it helps in the understanding of kinematics and can be used in the simulation of machines.","PeriodicalId":15681,"journal":{"name":"Journal of Engineering and Applied Sciences","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91193663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arabic Sentiment Analysis (SA) is a method responsible for analyzing people’s thoughts, feelings, and responses to a variety of products and services on social networking and commercial sites. Several researchers utilize sentiment analysis to determine the opinions of customers in various areas, including e-marketing, business, and other fields. Deep learning (DL) is a useful technology for developing sentiment analysis models to improve e-marketing operations. There are a few studies targeting Arabic sentiment analysis (ASA) in e-marketing using deep learning algorithms. Due to a number of difficulties in the Arabic language, such as the language’s morphological features, the diversity of dialects, and the absence of suitable corpora, sentiment analysis on Arabic material is restricted. In this paper, we will compare several Arabic sentiment analysis models. Also, we discuss the deep learning algorithms that are employed in Arabic sentiment analysis. The domain of the collected papers is Arabic sentiment analysis in e-marketing using deep learning. Our first contribution is to introduce and present deep learning models that are used in ASA. Secondly, investigate and study Arabic datasets utilized for Arabic sentence analysis. We create and develop a new Arabic dataset for Saudi Arabian communication companies, namely Sara-Dataset, to increase the quality and quantity of their services. Third, each collected study is assessed in terms of its methodology, contributions, deep learning techniques, performance, Arabic datasets in emarketing, and potential improvements in developing Arabic sentiment analysis models. Fourth, we analyzed several papers’ performance in terms of accuracy, F-measure, recall, pre-procession, and area under the curve (AUC). Also, our comparative analysis includes feature selection (e.g., domain-specific selection) methods that are used in Arabic sentiment analysis. Fifth, we also discuss how to improve Arabic sentiment analysis using preprocessing techniques (e.g., word embedding). Finally, we provide a design model for analyzing Arabic sentiment about communications services provided by Saudi Arabian enterprises.","PeriodicalId":15681,"journal":{"name":"Journal of Engineering and Applied Sciences","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87516608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advantages of SNAs are apparent in many sectors, with education being no exception. SNAs are also playing the main role in enhancing the quality of education. The aim of this paper is to explore SNAs use (e.g., Twitter, Facebook, and YouTube) in higher education students enrolled at Albaha University, Saudi Arabia, focusing on their associated advantages, barriers, and reasons for adoption, as well as differences between the participants with respect to the study variables. The research methodology was a survey approach and the sample size reached 243 students, including 123 males and 120 females. The survey was distributed to students electronically. The results indicate that most students benefit from SNAs, and these resources motivate them to engage with SNAs to enhance their education. Barriers were also identified that must be addressed for effective education. No difference was found between male and female students in terms of benefiting from SNAs, as well as the reasons and barriers, thereby indicating the availability of SNAs for both genders and the flexibility of their use at any time and place, as well as awareness in both genders about their use. A noticeable difference was identified in the extent of the benefits derived from SNAs between participants older and younger than 20 years, and differences were also found in the reasons underpinning these benefits. This reflects a disparity in the use and mastery of SNAs between the two age groups. Students aged 20-25 years also encountered greater barriers to SNAs use compared to students aged younger than 20 years, which may be attributed to the lower familiarity of older students with SNAs.","PeriodicalId":15681,"journal":{"name":"Journal of Engineering and Applied Sciences","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87793943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The massive amount of cyberattacks targeting Saudi Arabia can be attributed to the lack of cybersecurity awareness among Saudi people. The objective of this study is to propose methods on the national level to increase the awareness of cybersecurity among Saudi people. We conducted a cybersecurity assessment survey to assess the cybersecurity awareness among Saudi people. The survey result indicated negligent behavior and lack of awareness. To address this issue, we proposed a cybersecurity awareness framework which targets all strata of Saudi Arabia demography. The proposed framework not only emphasized training programs in schools, universities and organizations but also addresses the awareness issue in people from informal backgrounds.

Each cryptocurrency has its own unique hash value, and cryptocurrency mining involves participating in a guessing competition to release a unique hash into circulation, with the winner receiving a modest bonus in the form of bitcoin. However, as more bitcoins are discovered, it becomes increasingly difficult to obtain more, resulting in a need for extra computer resources and power. Consequently, the increasing popularity of cryptocurrency has led to a rise in cryptojacking malware, which secretly uses victims' computing resources to mine cryptocurrency. This malware can be either web-based or host-based, with similar execution and goals but differing in implementation and injection. Cryptojacking has affected numerous devices worldwide, but few studies have been carried out to detect it, especially the host-based type. Furthermore, the current studies on cryptojacking have limited datasets, which are often outdated or small, and the prediction models developed from these datasets may not be accurate. To address this gap, we conducted a thorough analysis of cryptojacking's behavior, lifecycle, impact, implementations, and possible detection methods. Additionally, we created an up-to-date dataset consisting of 114,985 samples, with 57,948 categorized as benign and 57,037 as cryptojacking. The dataset was used to build a smart cryptojacking detection system, with 5 different convolutional neural network models trained and evaluated against a subset of the dataset. The best performing model achieved an accuracy of 98.4%, an F1-Score of 98.3%, a precision of 98.4%, and a recall of 98.4%. Our proposed method, which involves running Windows executables in an isolated environment and closely monitoring their CPU usage, provides a thorough understanding of cryptojacking malware behavior and enables detection of the malware. The comprehensive dataset collected facilitates efficient detection model development. Additionally, evaluating the dataset with 5 different CNN algorithms and assessing their performance using established evaluation metrics ensures the effectiveness of our proposed method and dataset.","PeriodicalId":15681,"journal":{"name":"Journal of Engineering and Applied Sciences","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84253979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
