Comparison of Triple Exponential Smoothing and ARIMA in Predicting Cryptocurrency Prices

International Journal of Engineering, Science and Information Technology
Cryptocurrency has emerged as a prominent digital asset over the past decade, but its high price volatility presents significant challenges for investors. This study evaluates and compares the effectiveness of the Triple Exponential Smoothing (TES) and Autoregressive Integrated Moving Average (ARIMA) methods in forecasting the prices of five major ...

A Janus‐Like Bio‐Inspired Strategy for 3D‐Printed Bimetallic Metamaterials with Excellent Thermal‐Protection and Load Bearing Capacity

Advanced Science, EarlyView.
A Janus‐like bio‐inspired strategy is proposed for integrally 3D‐printed bimetallic metamaterials. Inspired by shell bilayers, a heat‐resistant AlSiFeMnNiMg alloy and a SiC‐reinforced AlSi10Mg with different SiC volume fractions are arranged as an architected pair.

Comparison of Double and Triple Exponential Smoothing Methods for Rainfall Prediction

Jurnal E-Komtek (Elektro-Komputer-Teknik)
Rainfall is water that falls to the ground surface over a certain period and is measured in millimeters (mm). Rainfall is essential for the life of living things. Forecasting plays a significant role in decision-making in modern times, with two main methods: causal models and time series.

Extending Carrier Diffusion via Interfacial Dielectric Shielding for Operationally Stable Perovskite/TOPCon Tandem Solar Cells

Advanced Science, EarlyView.
A high‐dielectric niobium oxide (NbOX) electron‐selective contact is introduced to modulate the perovskite/C60 interface in perovskite/silicon tandem solar cells. By shrinking the defect capture radius and chemically passivating Pb‐related defects, NbOX extends carrier diffusion length and optimizes energy‐level alignment, enabling both high efficiency

Multifunctional Phosphate Monomer Enabling LiNO3 Solvation and In Situ Formation of Flame‐Retardant Gel Polymer Electrolyte for High‐Voltage Lithium Metal Batteries

Advanced Science, EarlyView.
A phosphorus‐containing multifunctional monomer is successfully synthesized to simultaneously enable the dissolution of lithium nitrate in ester‐based electrolytes and in situ form a flame‐retardant gel polymer electrolyte (GPE). The formed GPE effectively stabilizes the structures of both the cathode and anode, thereby achieving superior long‐term ...
