Natural coagulants used were used with the aim of investigating their effectiveness in treating domestic wastewater compared to alum. One (1) litre of domestic wastewater was treated with fifteen (15) different total dosages of 0.8 g, 2.4 g and 4.0 g of banana peel, lemon peel and mixture of banana and lemon peels powder and one (1) dosage of 0.25 g of alum. The parameters tested were pH, turbidity, total dissolved solids (TDS), hardness and colour. The raw wastewater had values of pH, TDS, turbidity, colour and total hardness as 4.7, 901 mg/l, 899mg/l, 8440 pt-co and 1245 mg/l respectively. The best percentage removals were 86.2%, 73.7% and 76.4% for turbidity, TDS and colour at the optimum dosage of 2.4 g/l lemon peels powder. Lemon peel of 2.4g/l also led to improvement of pH from 4.7 to 6.5 (27.7% increase). Maximum hardness reduction was 24.9% with mixture of 0.6 g lemon and 0.2 g banana peels powder. Generally, lemon peels powder showed the potential to perform better as natural coagulant in wastewater treatment and in combination with banana peels. It gave better results than alum except in colour reduction which was 85.6% using alum. It is therefore recommended that lemon peel should be used for domestic wastewater treatment.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130481018","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}

Thermogravimetric and differential thermal analyses (TGA and DTA) were carried out on the MSW samples from three selected districts of Abuja metropolis under nitrogen atmosphere. The TG curves for samples from Lugbe and Dutse-Alhaji market are observed to have the same thermal behavioural trends which may be due to the presence of structural similarity of substances contained in the two samples compared to the behaviour of sample from Galadimawa district. It was observed that Galadimawa sample exhibited two stages of decomposition while Lugbe and Dutse-Alhaji samples have three main stages of decomposition. This study reveals that Abuja’s MSW have endothermic temperature peaks of 405.75 oC for sample from Lugbe district, 409.51 oC for Galadimawa district sample and 381.42 oC for sample taken from Dutse-Alhaji market, respectively. These values compare well with corresponding values for Nigerian coals (Enugu with 408 oC), thereby showing good thermal stability, and will be better and more economic fuel for energy generation than coal in addition to being renewable.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115794238","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}

Though is one of the state of the art hybridization methods for privacy preservation because of the Differential model and Homomorphic model strengths of the two hybridized models which are the ability to prevent composition problems and database attacks respectively.

While much research had focused on large scale companies, least attention had been paid to the small and medium-scale manufacturing industries which happen to be amongst the worst hit.This paper develops a model to support maintenance decision-making in a small and medium enterprise based on AHP. A total of 8 sachet water SMEs that met the inclusive criteria were selected. Six criteria were identified; consequences of failure, Ease of repair, Downtime, Frequency of failure, Cost of repair, and Cost of replacement and considered in the pair-wise comparative analysis. The developed model is targeted at addressing the fact that different components of the production equipment have disparate need for maintenance at any given maintenance schedule. Given that resources are often limited, it is cost-effective that choices of maintenance location be made such that the value added by the maintenance activities is optimized. The highlight of the analysis is the derivation of the Maintenance Significant Factor (MSF) that reflects the maintenance location-specific values of components. The result showed that the Submersible pump at an MSF value of 0.698 should attract utmost priority and closely followed by Automatic Production Machine and Modules at MSF of 0.555 and 0.447 respectively.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127955885","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}

Getting help depends on timely response from responders. Development in personal safety technologies have been improved over the years due to the increase in the use of mobile technologies and the miniaturization of electronic sensors. However, existing technologies for communicating distress usually require active user interventions in alerting emergencies. Hence, this study proposes a system for the automatic detection and alert of distress situations arising from violent attacks through smartphone sensors. A fuzzy logic approach was adopted to classify levels of distress situation using input data values from tri-axial accelerometer, gyroscope, sound and proximity sensors. A prototype of the distress detection and alert process was implemented using Java programming language. The system prototype was implemented as an android based real-time application that detects and alerts distress using values from mobile device sensors. Testing the prototype showed that the system can automatically detect and send alert to responders using smartphone.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121944315","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}

However, one camera at a single view point gait data has commonly been explored, this has not always sufficient enough in the environment of deployment. This research proposes gait analysis as a solution for subjects’ identification across a network of cameras from different viewpoints. Gait signature of a person is created from Temporal and spatial metrics extracted from modal, such as length of trunk, shin and deviation in the limb angles or the amplitude of a person’s walking pattern and these are transformed into a self-similarity matrix. The method of spatio-temporal correlation is to detect the human gait in successive video sequences. Performance evaluation of the system was carried out with CMU (Carnegie Mellon University) Motion of Body (MoBo) database. The results reveal that gait performance analysis of the proposed system is possible even without knowing the position of the camera or the stance of the subject. This research shows that the derived gait parameters suggest that gait may be successfully employed for individuals' identification with cameras surveillance in different view point scenario which resulted in an average recognition rate of 73.3% for persons walking from right camera viewpoints, 80.0% from persons walking from the left camera viewpoint, 60.0% from persons walking from the rare camera viewpoint and 66.67% from persons walking from the front camera viewpoint. This implies that the system performs better from the left camera viewpoint.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117032327","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}

It experiences power losses which could be technical or non-technical due to its radial configuration and connected components. Technical losses occur as energy dissipation in the form of heat in the system components, which is unavoidable. It affects the efficiency of the system and increases operational costs. Therefore, the reduction is essential for adequate power supply and improvement in utility revenue generation. This study focuses on reducing power losses on 11 kV Taiwo distribution feeder in Ilorin using the Network reconfiguration approach. The feeder was modelled, and its power losses were evaluated based on the Backward Forward Sweep method suitable for the radial network. The reconfigured network was optimised using the Particle Swarm Optimisation technique. The study shows that the values of feeder real power losses before and after reconfiguration are 176.883 kW and 121.972 kW, respectively.Further improvement was, however, achieved when PSO was used for the reconfiguration, as the power loss value stands at 98.465 kW. This is 44.33 % reduction compared to the initial power loss value and 19.273 % after reconfiguration. Furthermore, the values of the reactive power losses before and after reconfiguration are 9.474 kVar and 6.527 kVar, respectively, amounting to a 31.11 % reduction. However, PSO reduces the value to 3.101 kVar, which is 67.27 % of the initial value. Thus, radial distribution network reconfiguration using PSO has proven to be a robust method for reducing power loss in the distribution network.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115811582","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}

Automatic tuning has been an elusive goal for database technology for a long time and is becoming a pressing issue for modern E-services. One of the major difficulties in using antique methods to study such problems is the lack of accurate analytical methods for complex database systems. In the past, researchers were faced with complex problems of managing scalability as data increases and maintenance of database performance. Two Simulink models were developed, namely the conventional model and the optimized model. An integrated fuzzy logic proportional integral (PI) controller was used to simulate the proposed models. The optimized model of DBMS makes use of a combination of fuzzy controllers and data processing subsystems multiplexed with data access system. The simulation results of the two models were compared in areas of data flow rate, data access rate, data flow error and output rule behaviors. The results obtained proved the effectiveness of the optimized model which tends to provide stability to the system and minimize steady state error. In conclusion, the developed optimized model was able to improve the workload of the database management system with database stability of 60%, optimized flow rate of 50% and database access rate of 50%, respectively.","PeriodicalId":323504,"journal":{"name":"FUOYE Journal of Engineering and Technology","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115724311","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}
