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}
