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. The …

Climate Change and the Spread of Pathogens: Implications for Public Health
Abstract: Climate change plays a significant role in the spread of infectious diseases by shifting how pathogens behave, affecting how vulnerable hosts are, and changing the way diseases are transmitted.Rising global temperatures, changing precipitation levels, and extreme weather events are accelerating the spread of bacteria, viruses, fungi, and parasites, increasing the risk of outbreaks worldwide. Warmer conditions favor the survival and expansion of vector-borne diseases such as malaria, dengue, and Zika …

Comparative Analysis of Vertical Geometric Irregular Buildings by Fragility Curve Using Pushover Analysis
Abstract: The present work deals with the analysis of vertical geometric irregular structures, such as step buildings and setback buildings, which exhibit stiffness irregularity at different locations. These structures are analyzed using pushover analysis, a nonlinear static analysis method that provides insight into the performance of buildings under seismic loading by incrementally applying lateral forces until a target displacement is reached or the structure collapses. Stiffness irregularities in buildings can significantly …

Vibration control of a Plan irregular RC framed structure under seismic excitations with the help of TMD along with bracings
Abstract: The study of dynamic behavior of high-rise structures is immensely important as the dynamic response of the structures due to natural forces like seismic forces, wind forces etc. may result in structural failure. An unsymmetrically located shear wall or similar kind of stiff element may cause the structure to have plan irregularity. Such type of plan irregularity in high rise structure can induce the torsional displacements in the structure subjected …

Analysis of the Impact of Seabed Earthquakes on Coastal Structures and Foundation Design
Abstract: Earthquakes in the seabed occur with varying magnitudes. Seabed earthquakes cause a rapid rise in water levels, which can lead to flooding and structural damage. Therefore, when designing buildings near the seashore, it is essential to account for the additional load on columns due to water thrust. Earthquakes occurring at the seabed generate intense ground acceleration of varying magnitudes, significantly affecting water levels and inducing destructive flooding along coastal regions. …
