The proposed control law structures are based on the fractional order PI (FOPI) and the CRONE control schemes. By introducing the multimodel approach in the closed-loop system, the presented design methodology of fractional PID control and the CRONE control guarantees desired transients. Then, the multimodel approach is used to analyze the closed-loop system properties and to get explicit expressions for evaluation of the controller parameters. The tuning of the controller parameters is based on a constrained optimization algorithm. Simulation examples are presented to show the effectiveness of the proposed method.</p> Mohamed Lazhar Wardi Rihab Abdelkrim Messaoud Amairi Mohamed Naceur Abdelkrim Copyright (c) 2019 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) 2019-12-06 2019-12-06 62 1 1 19 Implant-prosthetic Rehabilitation after Removal of a Maxillary Cyst with Maxillary Sinus Involvement, without using Bone Augmentation Materials <p>Inflammatory odontogenic cysts are among the most frequent lesions of the maxillary bones. Through their evolution, these pathological formations may affect adjacent anatomical structures such as the nasal fossae or the maxillary sinus. Patient rehabilitation is a time-consuming process that can be a challenge for medical practitioners. In this study, authors present the case of a patient with a maxillary cyst involving the maxillary sinus, rehabilitated by implant-prosthetic treatment without using bone augmentation materials. Removal of the maxillary cyst was performed with the preservation of the maxillary sinus membrane, with apicectomy of the teeth adjacent to the cyst and extraction of the causative tooth. The post-cystectomy bone defect was protected with a pericardium membrane, and after 6 months postoperatively, a dental implant was placed in the edentulous area. Three years after cystectomy, the presence of mature bone in the defect area and the stability of the implant-prosthetic restoration could be observed. The rehabilitation method proved to be effective in obtaining a predictable and stable therapeutic outcome.</p> Raluca Iulia Juncar Daniela Popa Alexandru-Iosif Precup Mihai Juncar Copyright (c) 2019 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) 2019-12-06 2019-12-06 62 1 20 29 The Role of Knowledge Sharing in Organizational Performance <p>With the tremendous development in the current world, it has become necessary for organizations to convey with the rhythm of development in order to achieve the advantage of constructive competition with other organizations in their field. Where knowledge management is considered one of the methods used to raise the level of development, increase revenue and competitive advantage. The purpose of this paper is to discover the role of knowledge sharing in the organization in terms of increasing the effectiveness and efficiency, the significance of knowledge sharing, relationship between knowledge sharing and organizational leadership, the issues of knowledge sharing and how can be addressed. The applied method in this study is Qualitative Research which includes the use of non-statistical data to explain or explore a certain phenomenon. This paper has been failed to include the correspondence between knowledge sharing, employee motivation and performance, as this topic is also reflective of the extended role of knowledge sharing in the efficiency, satisfaction and retention of employees.&nbsp;&nbsp;&nbsp; &nbsp;</p> Zainab Al Kashari Fatma Al Taheri Copyright (c) 2019 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) 2019-12-09 2019-12-09 62 1 30 38
