Design and Analysis of MEMS based Piezoelectric Accelerometer Having Square Shaped Proof Mass
Abstract: In any spacecraft launching program, the most prominent issue is to locate the spacecraft or satellite, in particular orbit of any particular planet. Now, while making the position of that spacecraft in space, abrupt changes in velocity occur and these velocity changes can break the controlling circuitry of the system since the velocity changes occur at very high environmental pressure. The designed device converts the deflections due to mentioned pressure …

Comparison of Different Modulation Techniques for High Bandwidth Visible Light Communication
Abstract: Visible light communication (VLC) has gained tremendous importance due to its potential for ease, effectiveness and long lifetime. Slow response of phosphorescent components limits the modulation bandwidth of the white LED to the lower MHz range. Different modulation techniques have been used for VLC to achieve extended bandwidth, high data rate and bit-error-ratio within the forward error correction limit. This paper represents comparison of three different modulations techniques used for …

Intuitionistic Fuzzy Hypergraph Laplacians and Dominating Transversals for Resilient Discrete Network Design
Abstract: This manuscript develops a discrete mathematical framework for resilience analysis on networks whose interactions are polyadic, uncertain, and partially conflicting. Classical graphs compress multi-way coordination into pairwise edges, while ordinary fuzzy graphs often ignore the non-membership information that becomes critical in emergency logistics, infrastructure interdependence, and cyberphysical coordination. We therefore formulate an intuitionistic fuzzy hypergraph in which each vertex hyperedge incidence carries membership, non-membership, and hesitation, and we construct a …

Optimized Design and Control of Oil Exploitation Strategies: An Assisted Approach
Abstract: Because there are so many factors and scenarios to consider, optimizing oil exploitation tactics requires complicated decision-making. Conventional approaches frequently concentrate on particular elements of the design infrastructure, which restricts their capacity to fully handle the process. In order to maximize a set of oil exploitation variables in a hierarchical fashion, this research proposes a novel assisted optimization technique that combines mathematical algorithms with engineering analysis. By grouping variables into …
