Mechanical Pendulums vs 3D Fish Anatomy

In mechanics, in the area of dynamical system, a N-tuple pendulum is a set of N simple pendulums attached to each other. These N-tuple pendulums are physical systems that exibits rich dynamical behavior. For certain energies, are the motion of these mechanical pendulums often chaotic. You can influence the motion of the pendulums by holding your device in different positions. The equations of motions of these pendulums has been derived using the Sophia mechanical package. The different set of differential equations are solved using the 4:th order Runge-Kutta method for the time stepping. Within this application you can switch between these mechanical pendulums: - Double - Triple - Quadruple - Quintuple - Sextuple - Octuple - Symmtric Double - Simple 3-Dimensional The visualization of the pendulums can be viewed in either a Quartz view or in an OpenGL view.

The 3D Fish Anatomy app is an interactive model of a perch, a teleost fish. The software allows the visualization of details of internal and external anatomy of this ray-finned fish. The 3D Fish Anatomy app is an interactive model of a perch (Perca flavens) that allows for the animal internal systems to be viewed and manipulated layer by layer or simultaneously with other layers, at various zoom levels. Individual anatomical structures can be highlighted and display a caption, or they can be removed to permit viewing of deeper structures. This app is an ideal start in the study or teaching of Zoology, Ichthyology and Fish Biology. Available in English, Spanish, French and Brazilian Portuguese. This App is intended to be a supplemental educational resource and should NOT be used as the only source of educational information, nor should the Software be used as medical advice or for medical diagnoses of any kind.
