The efficiency of container handling has got great improvement with the usage of the 40ft quay crane and the twin 40 ft yard crane. Reasonable bay planning strategies is necessary to reach the high handing efficiency by the twin 40 ft yard crane. This paper studies both bay planning and row planning for yard bay allocation. The models of bay planning and row planning are created, and the discre...

In order to improve the operating efficiency of mixture storage yard, the problem of multiple yard cranes scheduling (MYCS) must to be solved. The paper develops a multiple yard cranes scheduling MIP model in order to minimize the sum of trucks’ waiting cost and yard cranes’ moving cost. An important feature is that the future has to be taken into account: the interference between two yard cran...

Evaluation of a variable Yd from certain measured variable(s) Xi(s), by making use of their system-specific-relationship (SSR), is generally referred as the indirect measurement. Naturally, the SSR may stand for a simple data-transformation process (Xi(s) Yd) in a given case, but a set of equations (fi({Yd}) = Xi, d, i = 1, 2, ..., N), or even a cascade of different such processes (“Xi(s) I Yd(...

The aim of this study is to propose a new mixed integer linear programming (MILP) model to find the minimum required number of yard cranes, Rubber tyred gantry cranes (RTGCs), for completion the total amount of works at the end of planning horizon. In other word, we find the optimal number of yard cranes in a container terminal which completes the total amount of works. The paper supports the p...

In today lives, daily trips of house inhabitants to out is made using closed staircase spaces or lobbies. Lack of a place for neighbourly relation results in less recognition and in some cases there is no neighbourly and friendly relationship. Families and especially kids surrounded in-house space so, today kids have less mobility and cause to depression of inhabitants of apartment houses. In a...

The General Yard Allocation Problem (GYAP) is a resource allocation problem faced by the Port of Singapore Authority. Here, space allocation for cargo is minimized for all incoming requests for space required in the yard within time intervals. The GYAP is NP-hard for which we propose several heuristic algorithms, including Tabu Search, Simulated Annealing, Genetic Algorithms and the recently em...

An analog of the Falconer distance problem in vector spaces over finite fields asks for the threshold α > 0 such that |∆(E)| & q whenever |E| & q, where E ⊂ Fq , the d-dimensional vector space over a finite field with q elements (not necessarily prime). Here ∆(E) = {(x1 − y1) 2 + · · ·+ (xd − yd) 2 : x, y ∈ E}. The second listed author and Misha Rudnev ([4]) established the threshold d+1 2 , an...

Abstract Media coverage of migrant and refugee camps often concerns not everyday life in camps, but violence or a camp's outright destruction. These portrayals risk inscribing into public memory as sites danger criminality, vulnerability without agency. What methods engaging with aftermath its representation might enable more complex understandings the reality camps? We engage camp site inscrip...
