Matching Ontologies for Emergency Evacuation Plans | A logic circuit incorporating carry look-ahead in which efficiency can be achieved regarding the hardware for generating the sum signals and carry signals by a suitable choice of the adder gate, making use of the already present signal &upbar& a1x &upbar& bi which is used for generating the carry look-ahead signal. |
High performance MIMO antenna for 5G wearable devices | In this paper, a dual-band 2×2 MIMO antenna for wearable device applications is presented to support the 5G radio frequency allocations at 3.3–3.6 and 4.5–5 GHz in China. The single antenna unit is composed of a monopole mode and a folded loop mode with a single feed to cover these two bands. Two identical antennas pos... |
A Novel Artificial Bee Colony Algorithm | Artificial bee colony algorithm is a new population-based evolutionary method based on the intelligent behavior of honey bee swarm. It has shown more effective than other biological-inspired algorithms. However, there are still insufficiencies in ABC algorithm, which is good at exploration but poor at exploitation and ... |
Efficient Mobile Robot Navigation using 3D Surfel Grid Maps | We present robust and efficient means for mobile robot navigation using a 3D representation of the environment. We build 3D surfel grid maps and propose Monte Carlo localization with probabilistic observation models for 2D and 3D sensors in such maps. In contrast to localization methods that utilize a 2D laser scanner ... |
