Due to the continuously increasing container trade, many terminals are presently operating at or close to capacity. An efficient terminal is one that facilitates the quick transshipment of containers to and from ships. In this sake, this paper addresses the ship assignments problem at a maritime container terminal, where ships are normally assigned to specific quay cranes until the work is fini...

In this paper, a new numerical method is presented for solving the optimal control problems of Bang-Bang type with free or fixed terminal time. The method is based on Bezier polynomials which are presented in any interval as $[t_0,t_f]$. The problems are reduced to a constrained problems which can be solved by using Lagrangian method. The constraints of these problems are terminal state and con...

intestinal lipomatosis also known as lipohyperplasia is a rare disease. diffuse infiltration of the fatty tissue mainly in the submucousal layer is characteristic. it is usually asymptomatic and found incidentally. we report a case of lipomatosis in the terminal ileum and ileocecal valve. multidetector computed tomography (mdct) with contrast enhancement showed fatty infiltration of the termina...

This study analyses the concept of cost functions for semi-automated Straddle Carrier (SC), Rubber Tyred Gantry (RTG) and automated Rail Mounted Gantry (RMG) container yard operating cranes. It develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

in countries such as iran which will be faced water deficit as the main challenge in the future and the food production is going to be dependent to water recourses, wheat water-deficit tolerant and adapted genotypes release is one of the most important strategies under such a condition. in order to study the adaptation and terminal water deficit stress tolerance, fifteen bread wheat lines and c...

Several years ago the authors of the present piece wrote a MONTHLY article [1] describing the velocity dependence of aerodynamic drag. Recently, a science reporter for the Guardian newspaper, who found this reference, solicited our help in writing an article about how a 102-year-old woman from Turin could fall out of a fourth floor window and survive [2]. In particular, the reporter wanted to k...
