Data-Driven Discrete Geofence Design Using Binary Quadratic Programming
Keisuke Otaki, Akihisa Okada, Tadayoshi Matsumori +1
Geofences have attracted significant attention in the design of spatial and virtual regions for managing and engaging spatiotemporal events. By using geofences to monitor human act…
Joint Optimization of Electric Vehicle Routes and Charging Locations through Learning Charge Constraints Using QUBO Solvers
Akihisa Okada, Keisuke Otaki, Hiroaki Yoshida
Optimal routing problems of electric vehicles (EVs) have attracted much attention in recent years, and installation of charging stations is an important issue for EVs. Hence, we fo…
Design Optimization of Noise Filter using Quantum Annealer
Akihisa Okada, Hiroaki Yoshida, Kiyosumi Kidono +3
The use of quantum annealers in black-box optimization to obtain the desired properties of a product with a small number of trials has attracted attention. However, the application…
Dynamical cooperation model for mitigating the segregation phase in Schelling's model
Akihisa Okada, Daisuke Inoue, Shihori Koyama +2
We consider a Schelling-like segregation model, in which the behavior of individual agents is determined by a mixed individual and global utility. With a high ratio of global utili…
Electro-osmotic diode based on colloidal nano-valves between double membranes
Shihori Koyama, Daisuke Inoue, Akihisa Okada +1
The rectification of electro-osmotic flows is important in micro/nano fluidics applications such as micro-pumps and energy conversion devices. Here, we propose a simple electro-osm…
Traffic Signal Optimization on a Square Lattice with Quantum Annealing
Daisuke Inoue, Akihisa Okada, Tadayoshi Matsumori +2
The spread of intelligent transportation systems in urban cities has caused heavy computational loads, requiring a novel architecture for managing large-scale traffic. In this stud…
