UWB outdoor and indoor base stations are used together
Ultrawideband's (UWB) unstable ranging results from the multipath effect and interference from non-line-of-sight (NLOS) indoors, which reduces positioning accuracy. Therefore, we have developed a distance-adaptive weighted positioning algorithm based on random forest (RF). . Ultrawideband (UWB) technology has been used for indoor location estimation due to its excellent ranging performance. Firstly, the. . An ultra-wideband indoor positioning system enables highly precise and accurate indoor positioning and UWB-based tracking of objects or individuals. UWB utilizes short-range radio waves with a large bandwidth, spanning across a wide frequency range. [PDF Version]

Do foldable containers reduce container fleet management costs?
The effect of foldable containers on the costs of container fleet management in liner shipping networks. Maritime Economics & Logistics. 2012. Vol. 14. No. 4. P. 455-479. DOI: 10.1057/mel.2012.16. Shintani, K. & Konings, R. & Imai, A. Combinable containers: A container innovation to save container fleet and empty container repositioning costs.
How much does a foldable container cost?
For the sensitivity analysis, the purchasing price of a foldable container is assumed to be twice as much as that of a standard container. Four foldable containers take up as much space as a standard container when folded and packed together. The folding and unfolding costs are the same; they are assumed to be approximately 50USD per handling.
Do foldable containers affect the shipping industry?
This paper analyzes the effect of foldable containers in various circumstances. Recently, as a result of the COVID-19 pandemic, many unexpected situations have arisen in the shipping and logistics industries. In this study, we examine three key situations: shutdowns, demand fluctuations, and fleet size fluctuations.
How much does a standard container cost?
The purchasing price of a standard container, which is amortized for a year, is 946USD per container for a shipping company while that price of a foldable container is 1,892USD per container. 5.2.1. Experiments on Models 1 and 2 Experiments are conducted to compare the cost of using standard containers with that of using foldable containers.
