The spring bounces back: introducing the strain elevation tension spring embedding algorithm for network representation

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

A spring-embedding approach for the facility layout problem

The facility layout problem is concerned with finding the most efficient arrangement of a given number of departments with unequal area requirements within a facility. The facility layout problem is a hard problem, and therefore, exact solution methods are only feasible for small or greatly restricted problems. In this paper, we propose a spring-embedding approach that unlike previous approache...

Stiffening Method for “spring-back” Reflectors

The recently proposed concept of spring back reflectors has revolutionised the field of deployable antenna structures. The whole structure is made as a single piece from composite material, without any expensive and potentially unreliable joints, and it is simply folded elastically about a central axis, like a taco shell. Shape distortions occur during manufacturing and are difficult to correct...
