The PI control scheme is proposed for the system, and it is usually used in DC motor drives. The proposed control schemes guarantee the asymptotic stability of the closed-loop system. The converter that is used in the system is a 4-quadratic switch-mode DC-DC converter. The design is based on a small signal model and verified using a large signal model. To illustrate the developed control schemes, the performance of the closed loop system is simulated using MATLAB. The simulation, analysis, and discussion are introduced to present the efficiency of the scheme.","PeriodicalId":13846,"journal":{"name":"International Journal for Scientific Research and Development","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135031911","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}

Our discussion is based on a simplified spectrum analysis, assuming a discrete character of the spectral components. In reality, a distribution of the hyperfine magnetic field, as well as isomer shift and the quadrupole splitting is an obvious and natural consequence of the finite size system 'presented by the monolayer film. The exact fitting of all hyperfine parameters distribution is too difficult.

In it and what is false or delusional. In the context of “urbanization” and its concept, the research shed light on the problem of progress according to Ibn Khaldun, and its connection to the concept of urbanization itself. It reviewed the conditions for achieving progress in human societies based on what can be deduced from the introduction. It is the political, economic, and ideological condition. Then he discussed the main features of progress as a social philosophical problem that was crystallized by Ibn Khaldun's personal interest in politics and society as a scholar and worker in both fields. In addition to its historical coincidence with the eras of decline and decline in Islamic history, which Ibn Khaldun was a witness to in the fourteenth and fifteenth centuries.","PeriodicalId":13846,"journal":{"name":"International Journal for Scientific Research and Development","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032855","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}

A total of 288 one-day-old broiler chicks (Ross -308) were randomly distributed among eight treatments, three replicates, and 12 birds per each replicate according to the complete random design (CRD). The first treatments were fed a basal diet (BD) and considered as a control treatment. The second treatment was fed BD supplemented with Neomycin as an antibiotic at 0.5 g/kg. Third, fourth, and fifth treatments were fed BD supplemented with Aloe vera powder at 5, 15, and 30 g/kg. Aloe vera gel at levels 5, 15, and 30 (ml/l) was administrated in drinking water to treatments sixth, seventh, and eighth respectively. Results indicated a significant improvement (P≤0.05) in final body weight (except T2 and T6) and total weight gain (except T6) for all supplemented treatments comparison to control. There was a significant decrease (p≤0.05) in total feed intake for all supplemented treatments as compared to the control, while there was a significant improvement in total feed conversion ratio in all supplemented treatments compared to the control. A significant increase (p≤0.05) in total water consumption in the T3, T4, T5 and T8 treatments as compared to control, and T2, T6, and T7, as well, a significant increase in the ratio of water consumption to feed for all supplemented treatments as compared with control. A significant increase (p≤0.05) in carcass weight and dressing percentage for all supplemented treatments except T2 and T6 as compared with the control. The performance index, production index, and protein efficiency ratio significantly were better than the control. In conclusion, Aloe vera leaf powder (5, 15, 30 g/kg) to broiler diets and leaf jell in drinking water (15 and 30 ml/l), could be used to improve production performance, carcass traits, performance index, production index, and protein efficiency ratio. The study also confirms that supplemented with 5 (g /kg) of Aloe vera leaf powder and 15-30 (ml /liter) of gel could be a successful alternative to the antibiotic Neomycin (0.5 g/ kg) in broiler diets.","PeriodicalId":13846,"journal":{"name":"International Journal for Scientific Research and Development","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032900","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}

To achieve the study purpose, the researcher adopted the descriptive analytical model as it suits this phenomenon. A group of variables that are expected to affect the inflation rate in the Saudi economy is selected. These variables are: money supply growth rate, imports of GDP, oil price growth rate, rate of exchange, income growth rate interest rate on the dollar and generate price level. Besides that, a standard model was built based on a series of data of inflation determents for the Saudi economy (1980-2016). The researcher also used the EViews program to tackle the relation among the variables and to obtain the best results. The study reached the following set of results: There is a direct relation between the inflation rate and money supply growth rate, imports of GDP, and general price level. Whereas the money supply growth rate has the strongest impact on inflation followed by imports of GDP, on the other hand, there is an inverse relation with both exchange rate. Meanwhile, the rest of the variables, oil price growth rate, income growth rate, and interest rate on the dollar have no effect on the inflation rate in Saudi Arabia.","PeriodicalId":13846,"journal":{"name":"International Journal for Scientific Research and Development","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135031726","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}

A set of English and Arabic sentences containing prepositional phrases were collected and analyzed for constraint violations. This study compared the syntactic structures of prepositional phrases in both languages by examining the case marking, headedness, and subject-verb agreement requirements of OT. The findings indicated that although prepositional phrases are used similarly in Arabic and English, there are also structural variations between them. In particular, the study finds that Arabic prepositional phrases exhibit more markedness and complexity than English preposition phrases, due to the influence of case marking and agreement constraints in OT. The study contributes to our understanding of the syntactic structures of preposition phrases in both languages and highlights the importance of considering the role of syntactic constraints in language comparison studies.","PeriodicalId":13846,"journal":{"name":"International Journal for Scientific Research and Development","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75282689","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}
