Objective: To evaluate the overall prevalence of Toxoplasma gondii infection among birds and poultries in Iran. Methods: Data were systematically collected from 1983 to 2016 in Iran on the following electronic databases: Pub Med, Google Scholar, Science Direct, Scopus, Web of Science, Magiran, Irandoc, Iran Medex, and Scientific Information Database. Additionally, the abstracts of national scientific congresses and dissertations were included. Results: A total of 20 articles in the field of birds and poultries toxoplasmosis, totally examining 4 563 cases with 754 positive results reporting the overall prevalence of infection from all parts of Iran could fulfill our eligibility criteria. The overall estimated prevalence included in chicken 20%(95% CI: 3% to 38%) in chicken, pigeons 8%(95% CI:-17% to 33%) and in sparrows 15%(95% CI:-25% to 54%). Conclusion: Although there is a lack in data about poultries and birds toxoplasmosis in Iran, our meta-analysis revealed that infection rate is high among birds and poultries in Iran. More studies are needed to manage controlling programs and prevention strategies among poultries in Iran.

Thanks to the emerging integration of algorithms and simulators, recent Driving Simulators (DS) find enormous potential in applications like advanced driver-assistance devices, analysis of driver’s behaviours, research and development of new vehicles and even for entertainment purposes. Driving simulators have been developed to reduce the cost of field studies, allow more flexible control over circumstances and measurements, and safely present hazardous conditions. The major challenge in a driving simulator is to reproduce realistic motions within hardware constraints. Motion Cueing Algorithm (MCA) guarantees a realistic motion perception in the simulator. However, the complex nature of the human perception system makes MCA implementation challenging. The present research aims to improve the performance of driving simulators by proposing and implementing the MCA algorithm as a control problem. The approach is realized using an actual vehicle model integrated with a detailed model of the human vestibular system, which accurately reproduces the driver’s perception. These perception motion signals are compared with simulated ones. A 2-DOF stabilized platform model is used to test the results from the two proposed control strategies, Proportional Integrator and Derivative (PID) and Model Predictive Control (MPC).
