Semilinear pseudo-parabolic equations on manifolds with ...
This paper studies the well-posedness of the semilinear pseudo-parabolic equations on manifolds with conical degeneration. By employing the Galerkin method and performing energy estimates, we first establish the local-in-time well-posedness of the solution. Moreover, to reveal the relationship between the initial datum and the global-in-time well-posedness of the solution we …
EE302 Lesson 13 Antenna Fundamentals.ppt
Conical Antenna A common way to increase bandwidth is to use a version of the dipole antenna known as the conical antenna. The center radiation resistance of a conical antenna is much higher than the 73 Ωusually found when straight-wire or tubing conductors are used. The primary advantage of conical antennas is their tremendous bandwidth.

FLOW PAST A SPHERE AT LOW REYNOLDS NUMBERS 5 We will make a start on the flow patterns and fluid forces associated with flow of a viscous fluid past a sphere by restricting consideration to low Reynolds numbers ρUD/μ (where, as before, U is the uniform approach velocity and D is the diameter of the sphere).
Conical Pendulum - The Fact Factor
A simple pendulum is a special case of a conical pendulum in which angle made by the string with vertical is zero i.e. θ = 0°. Then the period of the simple pendulum is given by. For conical pendulum θ < 10° time period obtained is almost the same as the time period for simple pendulum having the same length as that of the conical pendulum.

less constant. Therefore explaining the factor of 2πprob-ably requires a new idea. It too is due to Huygens. His idea [16, p. 79ff] is to analyze the motion of a conical pendulum: a pendulum moving in a horizontal circle. Although its motion is two dimensional, it is at constant speed, so it is easy to analyze without solving differen-tial ...

Lug Nuts: How to Know Which Lug Nut to Use | DrivingLine
The conical seat is a very common type of lug nut. You can differentiate this style by their cone shaped lug seats which feature a 60 degree taper that self-centers the lug onto the wheel when tightened down. Unlike the spherical seat, conical seats differ with their angled shape. They are often referred to as acorn lug nuts because of their ...
