Improved ultra wideband-based tracking of twin-receiver automated guided vehicles
In this paper, we present the design and performance analysis of an innovative system for tracking Automated Guided Vehicles AGVs in indoor industrial scenarios. An on-board odometer provides information about the dynamic state of the AGV, allowing to ...
A quadsection algorithm for grammar-based image compression
Grammar-based compression is to find a small grammar that generates a given data and has been well-studied in text compression. In this paper, we apply this methodology to compression of rectangular image data. We first define a context-free rectangular ...
Agent-based cloud workflow execution
Cloud computing offers an economical and feasible solution for scientific workflow applications requiring large amounts of computational resources and expensive hardware. Supporting Cloud workflow execution involves: i allocating and composing a ...
Vehicle-to-grid communication system for electric vehicle charging
Recently, the attention on electric vehicle EV/plug-in hybrid electric vehicle PHEV has been growing. The EV/PHEV will be one of important electric loads from the viewpoint of smart grid in near future. It is anticipated that the EV/PHEV will affect the ...
Intelligent supervisory control system for home devices using a cyber physical approach
Although we have many electric devices at home, there are just few systems to evaluate, monitor and control them. Sometimes users go out and leave their electric devices turned on what can cause energy wasting and dangerous situations. Therefore most of ...
A wavelet-based particle swarm optimization algorithm for digital image watermarking
Digital watermarking techniques have been proposed for copyright protection and multimedia data authentication. The achieved tradeoffs from these techniques between imperceptibility and robustness are always controversial. This paper proposes the ...
Ubiquitous web navigation through harvesting embedded semantic data: A mobile scenario
In this paper, we investigate how the Semantic Web can enhance web navigation and accessibility by following a hybrid approach of document-oriented and data-oriented considerations. Precisely, we propose a methodology for specifying, extracting, and ...
