Data-Driven Mission Recommendation for LEO Satellites using Random Forest and Hybrid Deep Learning Forecasting

This paper presents a data-driven framework for LAPAN-IPB LEO satellites that combines a Hybrid SARIMAX-LSTM voltage predictor and a Random Forest classifier to generate auditable, evidence-based mission recommendations, thereby replacing reliance on undocumented operator experience with a reproducible, objective scheduling process.

An REAE-LTransformer model for lithium-ion battery RUL prediction based on IFVIM

This paper proposes an REAE-LTransformer model optimized by an Improved Four-Vector Intelligent Metaheuristic (IFVIM) algorithm to accurately predict lithium-ion battery remaining useful life by effectively extracting degradation features, capturing long-term dependencies, and minimizing prediction errors, achieving superior performance with an MAE under 0.024 and R² exceeding 0.99 across multiple datasets.

A Scalable Hybrid Encryption Framework Based on Unimodular Hill Cipher, Logistic Chaotic Key Generation, and AES-CBC for Secure Binary File Protection

This paper proposes a scalable hybrid encryption framework that combines a password-derived Logistic Map for chaotic key generation, a dynamic Unimodular Hill Cipher for constructing large invertible matrices, and AES-CBC to provide robust, format-independent security for universal binary files with near-ideal entropy and strong resistance to cryptanalytic attacks.
