A few researchers recently integrated a microbial fuel cell (MFC) into an A2O process to generate electricity during wastewater treatment. However, no published studies show the outcome of combining the MFC with the reverse A2O process. The performance of a reverse A2O-MFC during the treatment of raw duck pond water was investigated in this study. For suitable electrode placement, nine patterns of anode and cathode location (CH01-CH09) were also investigated. As a result, 60-79%, 14-52%, 57-82%, and 50-82% of phosphates, nitrates, total ammonia nitrogen, and COD were removed, respectively. Lineweaver-Burk plots could be used to estimate the system's phosphate removal rates. The highest electrical energy was observed at CH05 (162.5 Wh) in the first period of the treatment operation and at CH02 (710.3 Wh) in the second period. The electrode placement patterns of CH05, where the anode and cathode were installed in an anaerobic tank and an oxic tank, and CH02, where the anode and cathode were installed in an anoxic tank and an anaerobic tank, were recommended for the reverse A2O-MFC with a 35-cm electrode distance.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"207 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72783622","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}

Healthcare sector has been deprived of leveraging knowledge gained through data insights, due to manual processes and legacy record-keeping methods. Outdated methods for maintaining healthcare records have not been proven sufficient for treating chronic diseases like diabetes. Data analysis methods such as Recommendation System (RS) can serve as a boon for treating diabetes. RS leverages predictive analysis and provides clinicians with information needed to determine the treatments to patients. Prescription-based Health Recommender System (HRS) is proposed in this paper which aids in recommending treatments by learning from the treatments prescribed to other patients diagnosed with diabetes. An Advanced Density-Based Spatial Clustering of Applications with Noise (DBSCAN) clustering is also proposed to cluster the data for deriving recommendations by using winnowing algorithm as a similarity measure. A parallel processing of data is applied using map-reduce to increase the efficiency & scalability of clustering process for effective treatment of diabetes. This paper provides a good picture of how the Map Reduce can benefit in increasing the efficiency and scalability of the HRS using clustering.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86478775","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}

This ozone machine, equipped with a centrifugal blower, could assist in thoroughly dispersing ozone gas throughout an enclosed area, as a result this ozone machine could raise the ozone concentration up to 2.4 ppm inside a 50 square-meter classroom after the ozonation period. Performances of this ozone machine were experimentally evaluated inside both non-ventilated and ventilated classrooms. First, an average total ozone dose of 58 ppmmin, which was close to an upper limit for the >90% viral disinfection, demonstrated the machine effectiveness in the viral inactivation. Second, a waiting period for ozone decomposition and removal using a ceiling ventilated fan could be predicted from an exponential decay rate of ozone concentration to be about 1.5 hour before the decontaminated room could be re-entered safely. Third, the disinfection of bacteria and fungi, which are tougher than most viruses, were validated by the cultural tests using standard plate count agars after the 50-minute ozone exposure. Results of the colony count and microorganism identification using the MALDI-TOF MS and the fungi slide culture technique revealed that 11 species of bacteria and 5 species of fungi could be inactivated by ozone gas after the specified ozonation period.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80722683","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}

Water scarcity problem in Thailand has been intensively addressed over decades to realize its impact and to promote a systematic modernization framework and technological advancement for effective and sustainable water resources management. Accordingly, the optimization – based solution with three scenarios was conducted by aiming to reduce water scarcity in the Greater Chao Phraya River Basin through re – operating the Bhumibol (BB) and Sirikit (SK) Reservoirs using non – linear programming solver. The results reveal that water deficit can be definitely reduced by the implementation of Fmincon optimization. Water allocation between BB and SK Dams was shared in the existing 0.44:0.56 ratio for scenario 1 and current operation and 0.45:0.55 ratio for scenario 2 and 3. The proportion of water released from SK Dam in dry years and normal years is still higher than BB Dam for all scenarios and higher than the current operation particularly in normal years. However, Fmincon optimization proposes to supply water from BB Dam higher than SK Dam in wet years with the average water sharing ratio of 0.54:0.46, 0.55:0.45, and 0.55:0.45 for scenario 1, 2, and 3, respectively. This leads to the increase in water storages of two main dams for a long – term reservoir operation.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73749915","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}

Food image classification is a challenging problem, the solution of which can be of great benefit to many real-world applications such as nutrition and allergy estimation. Most of the previous studies proposed to use variations of convolutional neural networks to tackle the problem. However, due to the limited number of annotated food image datasets, there is still some room for improvement, especially in terms of accuracy and speed. Generally speaking, neural networks trained to solve image classification problems on a small dataset benefit from utilizing the weights of the networks that have been pre-trained on a large image classification dataset such as ImageNet. In this paper, we compare the trade-offs between training networks from scratch, deploying pre-trained networks as feature extractors, and fine-tuning the networks for Thai food image classification. By utilizing Transfer Learning with EfficientNetV1, we were able to achieve higher accuracy for Thai Food Image Classification on the largest publicly available Thai food image dataset, THFOOD-50. In particular, our proposed method improves upon the accuracy of the previous state-of-the-art method from 84.06% to 91.49% while maintaining the speed for the prediction at 103 ms and 1205 ms for GPU and CPU, respectively.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74984469","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}

This research introduces a finite element method, considering size-dependent effect via nonlocal elasticity to analyze the buckling load of columns subjected to concentrated, distributed, and combined load cases. Two types of columns are considered: columns with a constant moment of inertia and nonuniform cross-section. The end conditions of columns comprise the following: clamped-free, hinged – hinged, clamped – hinged, and clamped – clamped. This paper illustrates the computational results using the relationship between buckling load normalized via the classical eigenvalue buckling load. The current findings show that the buckling load dramatically decreases at the normalized material length scale between 1 and 10. The most and least considerable effects on buckling load reduction are clamped – clamped and clamped-free end conditions. For the case of combined loads, a buckling concentrated load decreased proportionally as applied uniformly distributed force increased. An increase in concavity (or convexity) of parabolic columns will influence the buckling of the concentrated and uniformly distributed buckling loads.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90035149","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}
