    Abstract Introduction: Vascular dysregulation is a common underlying factor between migraine and glaucoma. Fluctuations in Ocular Perfusion Pressure (OPP) can lead to ischaemia and damage to the optic nerve head. It is unclear if the risk of glaucoma in migraine patients is due to low OPP. Aim: To compare the OPP of migraine patients with healthy controls and assess the role of OPP as a risk factor for glaucoma in migraine patients. Materials and Methods: This case-control study was conducted from June 2019 to May 2020 at Yenepoya Medical College Hospital, Mangaluru, Karnataka, India. Adult patients of either gender, aged between 18 and 40 years, diagnosed with migraine, were included in the study. Intraocular Pressure (IOP), blood pressure, and OPP were measured in 94 migraine patients and compared with 94 age-matched controls. Data were analysed using Statistical Package for the Social Sciences (SPSS) version 23.0. Independent t-tests were used for comparison. Adjusted odds ratios were calculated using binary logistic regression, and a p-value <0.05 was considered statistically significant. Results: The mean IOP was 13.27±2.02 mmHg among cases and 13.38±1.87 mmHg among controls. The mean Systolic Blood Pressure (SBP) was 118.91±4.67 mmHg among cases and 116.09±5.18 mmHg among controls. The mean Diastolic Blood Pressure (DBP) was 77.72±4.48 mmHg among cases and 75.77±4.89 mmHg among controls. The mean OPP was 47.69±2.43 mmHg among cases and 46.08±2.46 mmHg among controls. The t-test values showed a statistically significant difference in SBP, DBP, and OPP between the two groups (p-value<0.05). Conclusion: The OPP in migraine patients differed significantly from that of the controls. However, further studies are needed to evaluate the relationship between perfusion pressure abnormalities and the risk of glaucoma in migraine patients.

    Abstract This paper presents the interference suppression based on different beam form techniques. The Tire Pressure Monitoring System (TPMS) is a system for measuring the temperature and pressure of each tire of vehicles. In the past minimum-variance distortion less-response (MVDR) technique is used to removing the external interference and receiving the accurate data, but it is high computational complexity and high power consumption. In this work, we suggested a recursive least square algorithm (RLS) based on angle of arrival for suppress the interference, low computation complexity and low power consumption of a battery. The simulation results show the performance of different beam form techniques.
