Wireless power transfer is a modern technique used to transfer an electric energy from a source to a destination that is consumed to the load. Wireless power transfer is an important for many applications like, wirelessly powered home appliances that received the power from a transmitting device wirelessly. For example lighting of bulbs, operating of electric equipment and wireless charging for electric tooth brush and charging mobiles. In the developed countries there is wireless charging of electric vehicles is based on magnetic resonance field as in Japan. Based on this concept , the idea of this paper has been chosen. This paper aims to design a wireless power transfer system. This design has accomplished three tasks: one is to build a Tesla Tower design circuit and measuring the possible efficiency can be obtained. It's got satisfied results to about 70%. The second task is to build a magnetic coupled circuit that is based on the idea of wireless mobile charging technique. During our work, it's studied the power efficiency and its related to the distance between transmitter and receiver, the diameter of the coils and number of turns. To enhance our results, it's suggested to connect and design of these circuits by simulation using Multisim software and get the desired goal.","PeriodicalId":16911,"journal":{"name":"Journal of Pure & Applied Sciences","volume":"119 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77470774","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 Pavement Condition Index (PCI) and the international roughness index (IRI) are among the most commonly used indices to evaluate pavement conditions. Due to IRI data collection being more accessible and less expensive than collecting pavement distress data, this study aims to develop PCI models that can successfully estimate the PCI values based on IRI for flexible pavement using two Machine Learning techniques (ML), namely: Random Forest (RF), and Support Vector Machine (SVM), and three conventional techniques, namely: linear, quadratic, and cubic regression. The study was carried out with the database collected from the Long-Term Pavement Performance (LTPP) program. The results of the dataset reveal that both ML models (RF and SVM) have strong prediction ability with high values of coefficient of determination (R^2 = 99.7 and 96.8) %, and low values of Root Mean Squared Error (RMSE = 1.095 and 3.569) % and Mean Absolute Error (MAE = 0.474 and 2.244). In conclusion, the goodness of fit of the proposed ML models was compared with conventional techniques models previously developed. The results showed that the ML models yielded higher prediction accuracy than conventional techniques.","PeriodicalId":16911,"journal":{"name":"Journal of Pure & Applied Sciences","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78730739","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 study was carried out in western region of Libya and three Meriones rodents were collected and their genetic identification was conducted by PCR technique using designed forward and reverse primers from Meriones spp. cytochrome b (cytb) gene sequence. This study has differentiated three haplotypes of M. shawi. with sequences similarities between samples of haplotypes were 99.13%, 99.42% and 99.71% between H1 and H2, between H1 and H3 and between H2 and H3 respectively.

Due to the highly dense microstructure of RPC, it performs poorly at high temperatures due to the formation of high pore pressure, which causes material breakdown. This paper demonstrates the outcomes of an investigational study of the behavior of six RPC mixes incorporating hybrid steel and plastic waste (polypropylene) fibers after being subjected to high temperatures of up to 500 ºC. Residual compressive strength, residual splitting strength, and density were performed for all the RPC mixes. The results demonstrate that the drop in the compressive strength of RPC is greater than the reduction in their corresponding splitting strength. Furthermore, within a temperature range of about 500 ºC, this mechanical strength showed a noticeable decrease. The decrement of splitting strength ranged between about 8% to 33% . Steel and polypropylene fibers also improve the residual strength of RPC samples. On the basis of these results, a mix containing mixed fibers (25 % steel and 75 % polypropylene) is recommended as appropriate for extreme temperature applications.","PeriodicalId":16911,"journal":{"name":"Journal of Pure & Applied Sciences","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83496118","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}
