Since deriving a new model for tumor model is substantial, introduced system identification algorithms are used in order to estimate parameters of a specific nonlinear tumor model. Besides, in order to estimate tumor model a collection of output and input data is taken from the nonlinear system. Apart from that, effectiveness of the identification algorithms such as convergence rate and estimation error is depicted through various tables and figures. Finally, it is shown that the two stage approach has higher identification efficacy.</p> Kiavash Hossein Sadeghi Abohassan Razminia Abolfazl Simorgh Copyright (c) 2024 Kiavash Hossein Sadeghi, Abolhassan Razminia, Abolfaz Simorgh https://creativecommons.org/licenses/by/4.0 2024-02-20 2024-02-20 11 2 1–18 1–18 10.29121/ijetmr.v11.i2.2024.1403 MODELING AND OPTIMIZATION OF PERISTALTIC FLUID TRANSPORT IN AXISYMMETRIC, POROUS STRUCTURES https://www.granthaalayahpublication.org/ijetmr-ojms/ijetmr/article/view/1407 <p>Peristaltic transport, a fundamental physiological and engineering process, involves the movement of fluid through a distensible tube via sequential compression and relaxation. This study investigates the peristaltic transport of an incompressible Newtonian fluid in an axisymmetric, porous, corrugated tube, emphasizing the interplay between fluid dynamics and the tube's structural characteristics. Utilizing lubrication theory and perturbation analysis within a wave frame of reference, we explore the effects of hydraulic resistivity, geometric parameters of the corrugation, and porous layer thickness on the phenomena of trapping and circulation. Our findings reveal that hydraulic resistivity significantly influences the development of circulation regions within the fluid core, which has implications for the efficiency of mixing and nutrient absorption in biological and industrial applications. Additionally, the geometric configuration of the wavy porous layer—specifically its amplitude and thickness—critically impacts the formation of trapping and circulation regions, thereby affecting fluid transport efficiency. This work not only advances our understanding of peristaltic pumping mechanisms but also highlights the potential for optimizing fluid transport processes in both biological systems and industrial applications. The insights gained from this study contribute to the design of more efficient peristaltic pumps and offer a valuable framework for future research aimed at enhancing substance delivery and mixing through peristaltic transport.</p> Curtis Boodoo Copyright (c) 2024 Dr. Curtis Boodoo https://creativecommons.org/licenses/by/4.0 2024-02-22 2024-02-22 11 2 19–32 19–32 10.29121/ijetmr.v11.i2.2024.1407 THE MEDIATING ROLE OF ORGANIZATIONAL CULTURE ON THE RELATIONSHIP BETWEEN LEADERSHIP AND SOCIAL CAPITAL IN THE IRAQI SERVICE SECTOR https://www.granthaalayahpublication.org/ijetmr-ojms/ijetmr/article/view/1323 <p>This research intended to examine how organizational culture mediates the relationship between leadership and social capital in Iraqi service enterprises. The research used a descriptive-analytical approach, collecting data from a sample of 341 managers working in service firms in Iraq using a questionnaire. Total of (341) suitable surveys were collected for statistical analysis; the study used SPSS and Amos software’s to analyses the collected data and tests the hypotheses. The results of the study indicated that there is no impact of Authoritative and Facilitative leadership on the social capital of service companies in Iraq, there is an impact of Democratic and Situational leadership on the social capital of service companies in Iraq, and there is an impact of organizational culture on the relationship between leadership and social capital of service companies in Iraq. In light of these findings, the study recommended the need to pay attention to the quality of leaders who are appointed in service companies in Iraq due to the clear impact of the quality of leadership at the level of social capital practices of companies.</p> Majid Hamid Hazim Majid Raghad Raaed Mohammed Copyright (c) 2024 Majid Hamid Hazim Majid, Raghad Raaed Mohammed https://creativecommons.org/licenses/by/4.0 2024-02-28 2024-02-28 11 2 33–51 33–51 10.29121/ijetmr.v11.i2.2024.1323
