In this paper, we present a study of tuneable equilateral triangular shaped spilt ring resonator (ETSRR). In this ETSRR we rotate the inner and outer rings by varying the position of the splits in rings. For this we used radio frequency microelectromechanical system (RF MEMS) switches. By making MEMS switches ON/OFF, the positions of splits in the rings were varied which can be considered as ro...

In design for additive manufacturing, an essential task is to determine the optimal build orientation of a part according one or multiple factors. Heuristic search used by most methods select from large solution space. Search algorithms occasionally converge towards local optimum and waste considerable time on trial error. The above issues could be addressed if there was intelligent agent that ...

Swedish wheeled mobile robots have remarkable mobility properties allowing them to rotate and translate at the same time. Being holonomic systems, their kinematics model results in the possibility of designing separate and independent position and heading trajectory tracking control laws. Nevertheless, if these control laws should be implemented in the presence of unaccounted actuator saturatio...

To preserve eye contact in teleconferencing both the camera and the monitor need to be positioned on the same optical axis which, in practice, is usually not possible. We propose a method to construct the view from a virtual coaxial centered camera given two cameras mounted on either side of the monitor. Stereoscopic analysis of the two camera views provides a partial three-dimensional descript...

Using single-beam, oscillating optical tweezers we can trap and rotate rodshaped bacterial cells with respect to the optical axis. This technique allows imaging fluorescently labeled three-dimensional sub-cellular structures from different, optimized viewpoints. To illustrate our method we measure D, the radial width of the Z-ring in unconstricted Escherichia coli. We use cells that express Fts...

A flexible metamaterial RF detector for magnetic resonance imaging is described. The circuit consists of a polygonal arrangement of magnetically coupled L-C resonators with rectangular inductors, which supports magneto-inductive waves. The elements are mechanically linked to allow adjacent elements to rotate as the ring is flexed. The pivot is optimised to hold the nearest neighbour coupling co...

In this paper we propose a general method for creating a new type of hierarchical structures at any level in both 2D and 3D. A simple rule based on a rotate-and-mirror procedure is introduced to achieve multi-level hierarchies. These new hierarchical structures have remarkably few degrees of freedom compared to existing designs by other methods. More importantly, these structures exhibit synchr...
