A half-numeric method for Calculation the volume resulting from the intersection of a cylinder with a ball as a function of the impact parameter by using the Mathematical program mathCAD

We have developed an analytic expression for the volume of intersection of any cylinder with any sphere in the usual threedimensional space, and give examples of its usefulness for physics. Produced from surface collisions either elastic collision, or inelastic collision, for the incoming energies greater than the binding energy of the nucleons in the nucleus, the reaction occurs and thus the effective size (what the target nucleus see from the nuclear material in the projectle, and What the projectle see from the nuclear material in the target nucleus) is formed and so for the different collisions parameters .

Evaluating the residual structural strength of the ship after the collision accidents using numerical methods

Ship collision accidents are considered of the most serious incidents, due to the subsequent disastrous results both in terms of economic losses in ships and cargo, and the loss of human life as well as the great environmental pollution caused by it. Therefore, continuous efforts are being made by research centers in order to understand the structural response of the hull as a result of these incidents and accurately analyzed. This research is interested in assessing the residual structural strength of a ship exposed to collision through the internal energy and the various structural stresses generated within it. The case is modeled for an oil tanker exposed to collision by the bulbous bow of another vessel moves at different speeds and different angles. The structural strength of the middle section of the struck ship was analyzed based on the numerical methods using Ansys Dynamic Explicit program. Which allowed the development of a clear vision for the structural changes and internal stresses energy with time during the collision process.

Study of Barrier Coulomb, Concept of Trajectory, the Impact Factor, and Grazing Angle in Heavy Ion Collision

We have a detailed analytical study of the Coulomb barrier, the concept of collision factor, the concept of the trajectory, and the concept of grazing angle in a collision between heavy nuclei, and that for many of the symmetrical systems A1 equal A2 and asymmetric systems A1 doesn't equal A2 .The results obtained and presented for the first time in this way, help to differentiate between the electric interaction and the nuclear reaction, and then determine the energy ejaculation that should be used in order to show the interaction to be studied. On the one hand, on the other hand this helps to choice the detector (or detectors) that must be used in experimental work, and then where to put this detector (or these detectors).

The influence of elevated temperature on Collision induced absorption in gaseous oxygen (O2-O2) and mixtures of oxygen and nitrogen gases (O2-N2) in the wavelength range of 1.06 μm

Collisions induced absorption spectra of pure oxygen and gaseous mixtures of oxygen and nitrogen were measured at laboratory and studied, in the region of 1.06 μm, using Cary 5000 spectrophotometer, and White absorption gas cell with a path length fixed at 9.6 m. The mixing ratio of oxygen in nitrogen were 20%, 50% and 80%, at temperature 298, 323, 348, 373 K and pressures between 1 and 25 bar. The absorption band was centered at 1.06 μm, and raised as a wide continuum absorption, and did not show any rotational structure.
