The main objective of this work is to investigate the possibility of reusing treated water from the region. \u0000For this purpose, we have examined the quality of the water treated by the D'Ain El Arbaa treatment plant. \u0000The analyzes carried out on the incoming sewage and outgoing waste water from the lagoon focused on the following parameters: (pH, total suspended solids (TSS), biological oxygen demand (BOD5), chemical oxygen demand (COD), NH4, electrical conductivity). This during the period from January 2021 to May 2021 with a sampling frequency of twice a month. \u0000The results obtained show that this purification process using two sectors (pre-treatment, secondary treatment) is insufficient and does not meet the quality standards required for agricultural use for the parameters: TSS, COD, and electrical conductivity. For the preservation of the receiving environment, the results did not comply with the standards for the parameters TSS, DOC, NH4. \u0000 The abatement yields of the lagoon treatment plant studied were average for all the parameters studied. \u0000So according to this work we can conclude that natural lagooning alone is not sufficient to have purified water that complies neither with the quality required for agricultural reuse, nor with the quality required for discharge into the natural environment. \u0000Then the addition of a complementary tertiary treatment, such as filter basins planted with macrophytes is necessary.","PeriodicalId":12068,"journal":{"name":"European Journal of Science and Technology","volume":"141 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77117107","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}

Bu etkileşimlerin olumlu yanı olsa da olumsuz yanı da oldukça fazladır. Sosyal ağlarda kullanıcıların bilgilerini elde edip kullanıcıları taklit etmek güvenlik açısından büyük bir problemdir. Böylelikle kullanıcılar üzerinden dolandırıcılık vs. yapılabilmektedir. Kullanıcıları taklit edebilmek için en yaygın yol spam mesajların, e-postaların, vs. atılmasıdır. Güvenlik probleminin üstesinden gelmek için spam filtreleme, spam tespiti yöntemi geliştirme gibi işlemler uygulanmaktadır. Bu çalışmada Türkçe e-postalarda spam içeren e-postaların tespiti için Rastgele Orman, Lojistik Regresyon, Naive Bayes, Yapay Sinir Ağları makine öğrenme yöntemleri ve BERT, ELECTRA, ALBERT, DistilBERT dil modelleri analiz edilmiştir. Böylece dil modellerinin Türkçe için spam e-postaları sınıflandırmadaki etkisi gösterilmek istenmiştir. Deneysel çalışmaların sonucunda, spam e-postaları sınıflandırmada tüm dil modelleri makine öğrenme yöntemlerine göre daha başarılı olmuştur. Makine öğrenme yöntemlerinden yapay sinir ağları %90.15 doğrulu değeri elde ederken, en başarılı dil modelleri %94.08 doğruluk değeri ile BERT ve ELECTRA olmuştur.","PeriodicalId":12068,"journal":{"name":"European Journal of Science and Technology","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78469113","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}

In our study, we aimed to work with a large dataset and to achieve the best results in detecting malicious URL addresses using an artificial intelligence model. A 7-layer RNN model was used in the study, and two similar national and international datasets were combined and merged to create a big new dataset consisting of 579,112 URL addresses. Then, this new data set is divided into training and test sets. first data set was trained at the model and then the second data set was processed test. When this data set was processed in our model, we achieved a success rate of over 91%. This rate is a very good result of detecting malicious url addresses. Your contribution with this work is significant in developing more effective methods for detecting harmful sites as internet usage increases, parallel use of artificial intelligence models makes detection of such sites more effective and potentially assist users in protecting from various types of cyber-attacks is targeted.","PeriodicalId":12068,"journal":{"name":"European Journal of Science and Technology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81716058","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}

An off-grid system with 10KWh power consumption with optimum irradiance data has been found on how many square meters of PV system will be needed to operate it. How to meet the stable 10KWh need for the worst month, the amount of battery capacity required has been examined. A system inventory has been allocated. The province of Pamukkale in Turkey, with a latitude of 37.89°, was chosen for the solar panel installation; It is aimed to meet all the electricity needs of the house, which was built in a forest area 8 km away from the mains, with the solar panel system to be installed. From theory to practice with an academic approach as well as solar energy sector jargon; in this article, includes a two-way study. A solar panel system was installed in line with the data obtained and the 7600Wh value that the house to be built would need, and 29 batteries integrated into the system were sized for cases where the system could not provide sufficient energy through the sun with a 1% probability. Thus, the design of the optimum \"Solar Energy System\" desired for a certain location and compatible estimation calculations will be able to provide examples of this study.","PeriodicalId":12068,"journal":{"name":"European Journal of Science and Technology","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83225377","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}

Moreover, water quality (WQ) processes can be highly dependent on flow velocity conditions. Where, highly reaeration rates are positively correlated with high flow velocity. Therefore, the present work reports deep insights on the role of flow velocity with reaeration process in the concentration of DO and biochemical oxygen demand (BOD5). This study was applied along the largest agricultural drainage water reuse project, El-Salam Canal in Egypt. The hydrodynamic (HD) characteristics and WQ parameters (DO and BOD5) along the canal were simulated using a one-dimensional HD and WQ model (MIKE 11). The simulated results indicated that the canal was deteriorated towards El-Salam Canal after mixing with El-Serw and Bahr Hadous drains. Statistical regression fitted line and Pearson correlation analysis, were performed on the simulation results of the reaeration rates with flow velocity and WQ values, indicating a significant correlation. Accordingly, water velocity should be taken into account as a key factor for describing the WQ change.","PeriodicalId":12068,"journal":{"name":"European Journal of Science and Technology","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83311891","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}
