Solving shortage in a priceless market: Insights from blood donation.

Shortage is common in many markets, such as those for human organs or blood, but the problem is often difficult to solve through price adjustment, given safety and ethical concerns. In this paper, we study two non-price methods that are often used to alleviate shortage for human blood. The first method is informing existing donors of a current shortage via a mobile message and encouraging them ...

A Super - Element Based on Finite Element Method for Latticed Columns Computational Aspect and Numerical Results

This paper presents a new super-element with twelve degrees of freedom for latticed columns. This elements is developed such that it behaves, with an acceptable approximation, in the same manner as a reference model does. The reference model is constructed by using many Solid elements. The cross section area, moments of inertia, shear coefficient and torsoinal rigidity of the developed new elem...
