A coupled spring-pendulum system in a conservative field was studied where the equation of motion using Lagrangian and Hamiltonian were obtained. The represented by second-order differential from three generalized coordinate used. potential energy equal to zero when is its equilibrium position. that being used angle first pendulum θ_1, second θ_2, increase length spring x. resulting can be dete...

The paper describes a novel multi-resolution registration method. It is fast, robust and offers high registration accuracy. The algorithm models deformations using an elastic spring mass system, which contains sparse masses interconnected by springs. The proposed method uses data intensity values to guide deformation with local constraints imposed by interaction of interconnecting springs. More...

The equations of planar motion of a mass attached to two anchored massless springs form a symmetric Hamiltonian system. The system has a single dimensionless parameter L, corresponding to the spacing between the anchors. For L > 1, there is a stable equilibrium at which the springs are in tension and lie on a line, but for L < 1, this equilibrium has both springs in compression, and is unstable...

Convective activity occurs more commonly and frequently across the United States during the spring and summer (nominally, the period of May through September). While distribution of the activity has been examined both temporally (time of maximum activity and severity) and spatially (e.g., nationally as well as regional variations) to depict its characteristic time of occurrence and pattern, ver...

In European Robins, Erithacus rubecula, the magnetic compass is lateralized in favor of the right eye/left hemisphere of the brain. This lateralization develops during the first winter and initially shows a great plasticity. During the first spring migration, it can be temporarily removed by covering the right eye. In the present paper, we used the migratory orientation of robins to analyze the...

Title of Document: THE HYDROLOGIC AND WATER QUALITY PERFORMANCE OF THE SLIGO-DENNIS BIORETENTION CELL. Jennifer M. Olszewski, Master of Science, 2010 Directed By: Professor Allen P. Davis Civil and Environmental Engineering Bioretention cells have been found to improve the hydrologic and water quality performance of impervious areas such as parking lots. The current study recorded hydrologic da...

Modeling a system means developing mathematical representation to simulate certain properties observed in real systems. These systems can range from car suspension the most complex robotics. In modern mechanical engineering, it is routine model physical dynamic as set of differential equations that will later be simulated using computer. This Use software for numerical analysis and qualitative ...

Spring mounds on Earth and on Mars could represent optimal niches of life development. If life ever occurred on Mars, ancient spring deposits would be excellent localities to search for morphological or chemical remnants of an ancient biosphere. In this work, we investigate models of formation and activity of well-exposed spring mounds in the Mechertate-Chrita-Sidi El Hani (MCSH) system, easter...
