Dynamics of flight of the fragments with higher order Haar wavelet method [PDF]
Fragments that have an irregular shape and move at high speeds are difficult to assess since experiments require high-tech solutions, and the differential equations that describe the motion cannot be solved analytically.

Perturbations of the Haar wavelet [PDF]
Summary: Let \(m \in Z^+\) be given. For any \(\varepsilon > 0\) we construct a function \(f^{\{\varepsilon \}}\) having the following properties: (a) \(f^{\{\varepsilon \}}\) has support in \([-\varepsilon , 1 + \varepsilon ]\). (b) \(f^{\{\varepsilon \}} \in C^m(-\infty , \infty)\).

Simulation of a non‐linear, time‐variant circuit using the Haar wavelet transform
Wavelet theory has disentangled numerous complexities, including those pertinent to transient and steady‐state responses of systems, when Laplace and Fourier transforms face insoluble obstacles. Reactive linear components (e.g.
