Reliability-Aware Mathematical Model for Radiation-Hardened Satellite Communication Systems
Abstract: Satellite communication systems operate in radiation environments in which total ionizing dose (TID), displacement damage, and single-event effects (SEE) can progressively degrade electronic, optoelectronic, and communication components and can ultimately reduce link availability and mission reliability. This paper develops a Reliability-Aware Radiation-Hardened Satellite Communication Model (R-RHSCM) that mathematically couples the orbital radiation environment, accumulated radiation dose, component degradation, communication-link performance, single-event failure probability, redundancy, thermal effects, and adaptive mitigation.

Modelling and H∞ Robust Control of a Neonatal Incubator
Abstract: This study presents the modelling of a neonatal incubator and the design of a robust H∞ controller. Neonates, who are born premature, often don’t have enough maturity to regulate their temperature. These infants have low metabolic heat production rate and may have high heat loss from the skin so they have an increased risk of death in the first week of their life. The core temperature of the human body …
