This article presents a numerical investigation of mass and heat transfer effects on an unsteady Magnetohydrodynamic (MHD) nanofluid flow in a permeable pipe. The influences of the chemical reaction and magnetic flux are considered. With the central finite-difference technique, the fundamental equations are discretized. The resulting equations are solved numerically using methods of lines, bvp4, and shooting methods. The influences of material factors on the solution are investigated and displayed through tabular and graphical illustrations. The study revealed that the Sherwood number, skin friction, and rate of heat transfer are all decreased by an increase in the magnetic field. Additionally, the rate of rise of the chemical reaction and Brownian motion is observed to reduce the concentration of the nanofluid. Furthermore, the study finds that the Soret number, porosity medium resistance parameter, and thermophoresis parameter all cause the concentration profile to climb; while, increasing the pace of the chemical reaction and brown mobility leads the profile to decline. Key words: Chemical reaction, porous medium, magnetohydrodynamic (MHD, nanofluid.

Recently, American Sign Language has been widely researched to help disabled people to communicate with others. However; the Arabic Sign Language “ASL” has received much less attention. This paper has proposed a smart glove which has been designed using flex sensors to collect a dataset about hand gestures applying ASL. The dataset is composed of resistance and voltage measurements for the bending of the fingers to represent alpha-numeric characters. The measurements are manipulated using normalization and zero referencing methods to create the dataset. A Convolutional Neural Network ‘CNN’ composed of twenty-one layers is proposed. The dataset is used to train the CNN, and the Accuracy and Loss parameters are used to characterize its success. The dataset is classified with an average success rate of 95% based on the classification accuracy. Loss has decreased from 3 to less than 0.5. The proposed CNN layers have classified ASL characters with a reasonable degree of accuracy.

Leakages in a pipeline are an important problem due to the potential economic and environmental hazard they present. In this study, we proposed a LoRaWAN-based approach for detecting and localizing leakages in pipelines. Our study includes an experimental setup that simulates a pipeline network with pressure and flow rate sensors attached. The flow rate and pressure data were transmitted through LoRaWAN to a receiver, which in turn uploads the data to a cloud server using a cellular network. The receiver compares the flow rate reading from all the monitoring nodes attached to the pipeline network. If flow rate reading from successive nodes presents a percentage variation of more than 1.5%, a leak is confirmed to have taken place. The flow rate readings can also be used to localize the leak. The resolution of the leak detection is dependent on the number of monitoring nodes on the pipeline network. In our study, the pressure readings were found to be insufficient to provide reliable evidence of leakages. In our specific situation, due to the relatively short length of the experimental pipeline network, a pressure drop of up to 38.2% was recorded between successive nodes with an overall pressure loss of 62%, making pressure data unsuitable for leak detection in the short pipeline network.

The Wave Energy Conversion System (WECS) control strategy is presented in this study to make sure the system operates at its best under fluctuating wave resource situations. The suggested system consists of a MOPSO based MPC approach, a point absorber WEC oscillating in heave, back-to-back power converter for grid connections, and a linear permanent magnet generator. Despite the benefits of model predictive control, problems including switching frequency variations, steady-state errors, high processing costs, and constrained prediction horizons continue to exist. The article presents a method that incorporates the switching control action into the cost function while maintaining the finite nature of a model predictive control to handle the switching frequency issue. In order to minimise switching frequency variations while also addressing other control goals, such as regulating the direct current linked voltage and controlling the flow of active and reactive power, the switching control weight factors are optimised. In order to increase power quality, a fuel cell-based short-term energy storage system is also included to direct current link between the back-to-back converters.

The need for bioenergy as a sustainable alternative to fossil fuels is increasing, and the production of biofuels using bacteria is considered one of the prominent methods used in this field. This research aims to model the process of producing biofuels using bacteria and storing them using a chemical storage system. A mathematical model was used to analyse the process, where the chemical constants and optimal environmental conditions for the process were determined. The process variables were identified, including acidity level, increased production coefficient, and the effect of thermal variables on the process. The productivity and efficiency of the process of producing biofuels using bacteria were analysed, and the effect of environmental variables on this process was studied. The produced biofuels were stored in a chemical storage system, where the system was analysed, and the appropriate conditions for safely storing biofuels were determined. The data resulting from the mathematical model and the storage system were analysed and graphed. The research concluded that biofuels can be efficiently produced using bacteria and safely stored using a chemical storage system. The effect of environmental variables was analysed, and the chemical constants used in the mathematical model were optimized, resulting in a significant improvement in the efficiency of the process. The results of this research can be used to improve the process of producing biofuels and develop safer and more efficient storage systems for biofuels.

The software product is high used by the society in general and its development complexity are inputs of this research that gears into the software development processes. The mapping and modelling of software processes, as well as their standardization are not trivial tasks in the industry of software. Therefore, process mining practices can be useful for discovering or validating processes. This article presents a hypothetical software development project that uses the agile SCRUM method, Jira software, Jenkins pipeline and a process mining tool called ProM. As the project team generates many records using the software development tools, these records are considered event logs and it is be used during process mining activities. ProM allows users to identify processes from the event logs and is used with the records generated by Jira and Jenkins. The visualization of a possible process derived from the use of these event logs is presented when using the ProM tool and the Flexible Heuristics Miner algorithm. In conclusion, process mining can be useful to discover or validate existing software processes during the execution of a software project, also allowing these processes to be standardized to be used in future projects.

Spectral methods for the solution of a boundary value problem of an ordinary differential equation are reviewed with particular emphasis laid on pseudo-spectral collocation method. The pseudo-collocation method is then used to solve the one dimensional bio-heat equation with metabolic heat generation in cylindrical coordinates applied to human tissue. It was noticed that an increase in heat transfer coefficient (hA), enhanced the temperature but a decrease in the tissue thickness was observed when this coefficient was increased. The effects of the combined heat transfer coefficient are analyzed and the results indicate that the obtained solution can be used in the study of the thermal behaviour of a biological system with the potential to locate tumours in the living tissue.

The technical cost incurred in providing adequate services for drinkable water production and distribution is high in developing countries of which Nigeria is no exception. By analysing the energy aspect of this cost, with a view of eliminating non-value-adding energy wastes, the cost of production can be reduced. In this work, an energy audit of the University of Ibadan water factory has been carried out, as a means of reducing the electrical energy wastes within the factory, as well as the associated costs to these energy wastes. Data on equipment being used and their power ratings were collected via walkthrough audit, by means of interviews and personnel observation, and thereafter inputted into Excel spreadsheet in order to determine the extent of energy consumption of each of the factory equipment, areas of energy wastage and areas of energy conservation opportunities. The factory’s structural data was obtained through the use of a 50m fibre measuring tape, in order to carry out lighting, air-conditioning and ventilation assessments on selected rooms in the factory, as means of proper energy conservation. Energy management measures were deployed by suggestion of more efficient equipment. Major equipment found includes automatic filling machine, pumps, steam generator, conveyor etc. The total electrical energy consumption of the factory was 9,280.899 kWh, of which equipment such as pumps took 20% (highest energy consumption). Areas of major energy consumption include pet blowing room, production room 1, production room 2 and the borehole area. While the current cooling capacities of most rooms in the factory were above the cooling requirement of each room, the luminosity requirement of selected rooms in the factory is surpassed by the current luminosity level found. Energy management measures were found to reduce the energy consumption of the factory by 17%, saving a sum of 87,906.207 naira of electrical energy cost monthly. In conclusion, the energy audit carried out on the University of Ibadan water factory was found useful in reducing energy waste and associated costs within the water factory. This approach can be applied in industries for electricity cost reduction, hence, production cost.

Unit weight and elastic modulus of concrete utilizing volcanic stone waste (VSW) as coarse aggregate have been studied at 28 days of hydration. The origin of VSW was the residual of volcanic stone processing for making the handmade ornaments of traditional Balinese buildings. Three types of concrete mixture compositions were made by varying the proportion of cement, fine aggregate and coarse aggregate in concrete. Each mixture composition stirred using four variations of water/cement (w/c) ratio. For each variation in w/c, five cylindrical specimens with a diameter of 150 mm and a height of 300 mm were made to measure the unit weight and modulus of elasticity of concrete specimens after 28 days of hydration. The result shows that the unit weight and the elastic modulus of concrete decrease with increasing w/c at fixed proportions of cement and aggregates and increase with increasing proportion of aggregates at fixed w/c. The increase in elastic modulus with an increase in the a/c ratio for a fixed w/c ratio is more noticeable for a w/c ratio of more than 0.6. Moreover, the elastic modulus increases correspondingly with an increase in unit weight for a given a/c ratio.

Moreover, the elastic modulus increases correspondingly with an increase in unit weight for a given a/c ratio.","PeriodicalId":12001,"journal":{"name":"European Journal of Engineering and Technology Research","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75902882","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}
