Displacement Method of Structural Analysis

The displacement method (also called the stiffness method or equilibrium method) is the second fundamental approach to analysing statically indeterminate structures. Instead of treating unknown forces as primary unknowns, the displacement method takes joint displacements and rotations as unknowns and enforces equilibrium at every free joint.

Loss Functions in Artificial Neural Networks

In the realm of artificial neural networks (ANNs), the loss function serves as a critical component that guides the training process. It quantifies the difference between the model's predictions and the actual target values, enabling optimization algorithms to adjust the network's parameters for better performance.
