Online shops are responsible for a significant increase in the total volume of parcels which have to be transported. Due to the increase in volume there are more vehicles required to meet this enormous demand. This has a negative impact on the traffic flow on the infrastructure. A possible solution can be found in ride-sharing, as sharing...

As machines and robots become a increasingly larger part of society, it is important that they are fully accepted. If the machines are not utilized as intended, it is not only a waste of time and energy, but also of valuable resources. This acceptance by humans of robots is based on how well the interaction with robots is trusted. Trust of...

This paper discusses an elastic metamaterial for filtering energy from certain frequencies of an incoming wave. The unit cell, which is composed by a single material, is built to obtain a local resonance band gap. Since Bloch-Floquet's periodic condition is enforced to the unit cell, the dynamic characteristics of the metamaterial is obtained...
