- Exploration is the fundamental task of guiding a robot autonomously during mapping so that it covers the entire environment with its sensors. In the frontier-based exploration, a...
Coverage configuration is an important issue in large scale wireless sensor networks (WSNs). Existing coverage configuration methods are generally based on the concept of physical...
When magnifying a bitmapped image, we want to increase the number of pixels it covers, allowing for finer details in the image, which are not visible in the original image. Simple...
In this paper, we study the trade-off in steganography between the number of embedding changes and their amplitude. We assume that each element of the cover image is assigned a sc...
Location-based applications and services are getting increasingly important for mobile users. They take into account a mobile user's current location and provide a location-d...
