In the present study, we consider canal surfaces imbedded in an Euclidean space of four dimensions. The curvature properties of these surface are investigated with respect to the variation of the normal vectors and curvature ellipse. We also give some spe... see more

In this work we will deal with ellipses and ovals, comparing them both from the geometric point of view and from the one of applications. There is a notable similarity between these curves so often it’s not possible to recognize which of the two figures i... see more

This paper has academic nature, nevertheless it is an application from [9] that we think can be interesting  to students and instructors of undergraduate level of physics. With low level of geometric and computational techniques the readers can repro... see more

The elliptic curves possess a certain disadvantage related to that at the point of intersection with the coordinate axes the ellipses have tangents perpendicular to these axes. However, such a situation is undesirable for some practical applications of el... see more

The aim of the research was to demonstrate the differences in amplitudes of postural reactions in girls with scoliotic posture and idiopathic scoliosis. 28 girls aged 7-18 years old were involved in the study. Children attended to the Interschool Centre o... see more

Internal flows in pipes are studied in greater depth and comprehensiveness in research. The computation done by using RANS equation. In particular, this study uses two equations turbulence model which is k-ε turbulence model. Mesh with 2×106 element is ... see more

This note is an effort to understand how curvature obstructs the integrability of almost-complex structures.

The exactness in determining the radius of curvature of the downstream toe of a spillway ensures a smooth hydraulic transit from the upstream to the downstream of the structure. The literature mentions that this radius takes half the height of the dam if ... see more

Mandeh Bay is threatened by sedimentation issue caused by the rapid development of marine tourism area which strongly impacts to the environmental degradation. Due to the semi-enclosed area of Mandeh Bay, the tidal current has a significant role in trigge... see more
