Nonlinear Dynamics of MEMS Resonator with Squeeze-film Damping
Abstract: This paper presents nonlinear dynamic analysis of electro-statically actuated micro-resonator under squeeze-film damping conditions. By considering a single degree-of-freedom oscillator model of resonator with squeeze-film damping effects, nonlinear phenomena are investigated. Numerical studies are conducted using phase portrait and Poincare map over a range of AC voltage amplitudes to predict the dynamic pull-in state. The effects of AC harmonic frequency and ambient pressure on beam dynamics have also been studied. …

Rising Temperatures and Surface Mass Loss in Greenland: Implications for Regional Glacier Dynamics and Global Sea Level Rise
Abstract: In Greenland, the ice sheet serves as one of the strongest indicators of global climate change, with consistently rising temperatures driving it toward an even more negative mass balance. Over the last two decades, warmer conditions have exacerbated surface melting, darkened ice, and resulted in feedback stimulating further loss. This study assesses how those temperature trends—particularly during summer peak months—have impacted the stability of Greenland's ice, and then, more importantly, …

Dynamic Analysis of Railway track and SSI effect
Abstract: The analysis of dynamic behavior of bridge structures that are subjected to moving loads has been one of the research interests in recent years. Specifically in railway bridges, Resonance occurs when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been observed in railway bridges especially subjected to High Speed Lines. They are caused mainly because of two reasons one is the …

Ascendancy of connecting assymmetrical r.c. towers using sky bridges in improving the dynamic response
Abstract: Structures constructed to serve similar purposes adjacently, are often connected to each other. These connections may be sometimes in the form of sky-bridges. Connecting the structures with each other does not cause any modification in the behaviour of the structures in the static condition, but such modification may cause huge effects on the structural behaviour under dynamically activated condition. This article basically deals with study of connected structures, when connected …

Abstract: Voltage over-scaling has been a possibility for energy dependability compromise. This research will look into its effectiveness and the potential for rationale deferral flaws. Our contextual investigation on an ARM Cortex-M0 processor with business 45 nm libraries shows that the quantity of defer deficiencies increments decisively after the principal bombing working point which infers that voltage overscaling will be wasteful after the basic working point.

Abstract: This study proposes a simple and effective heuristic to save memory in effective programming on tree decompositions when solving a graph optimization problem. The introduced “anchor technique” is based on a tree-like set covering problem. We substantiated our findings by experimental results. Our strategy has negligible computational overhead concerning running time but achieves memory savings for nice tree decompositions and path decompositions between 60% and 98%.
