Time delay spread and path loss measurements were performed in a large, active train yard to support development of intra-yard wireless communication systems, such as those intended to communicate with individual railcars and for track-to-terminal communications. Propagation measurements focused on three sites within the train yard: a close-in site, a paralleltrack site, and a cross-track site....
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...
This article describes the sense-making process we applied to solve the VAST 2010 Mini Challenge 1 using the visual analytics system Jigsaw. We focus on Jigsaw’s data ingest and evidence marshalling features and discuss how they are beneficial for a holistic sense-making experience.
The train marshalling problem is about reordering the cars of a train using as few auxiliary rails as possible. The problem is known to be NP-complete. We show that it is fixed parameter tractable (FPT) with the number of auxiliary rails as parameter.
In this work, we address the unrestricted Dynamic Container Relocation Problem (DCRP). The DCRP is an extension of the Container Relocation Problem (CRP) that is NPhard. The CRP aims to empty a single yard-bay, which contains containers with a given retrieval sequence from the yardbay, such that the total number of relocations is minimized. The DCRP extends the CRP so that containers both arriv...
In container terminal operations, the storage yard plays an important role for a terminal’s overall performance because it links the seaside and landside and serves as the buffer area for storing containers. Therefore, storage and stacking logistics has become a field that increasingly attracts attentions in both academic and practical research during the recent years. The purpose of this artic...
