Terahertz dielectric resonator antennas (DRAs) provide ultrafast data transfer rates using large bandwidth and multimode operations, which make them ideal for high speed communication due to their low loss and high efficiency. They can work at microwave, terahertz or optical frequencies, and are compact in size, which makes them well suited for advanced applications in sensing, scanning and imaging. New geometries are being developed for conical optical DRAs, cylindrical optical DRAs and spherical optical DRAs. Spherical optical DRAs have features of super directivity which can be used in quantum radars. Cylindrical optical DRAs with photo diodes can be used for wireless energy harvesting.

Performing triage requires the ability to make quick, evidence-based decisions based on limited information. Nurses are often required to preform triage either over the phone, in urgent care settings, in the emergency department, and even in office settings. This reference provides over 200 triage protocols for evaluating a person's symptoms. Each symptom entry lists pertinent questions grouped by urgency level and advises the clinician when and where the patient should be referred. This book is a need to have, comprehensive, user-friendly resource for every nurse who performs triage.

Reluctance motors induce non-permanent magnetic poles on the ferromagnetic rotor; the rotor does not have any windings and torque is generated through magnetic reluctance. Synchronous reluctance motors (SyRMs) have an equal number of stator aand rotor poles. Reluctance motors can deliver high power density at low cost, so they are finding increasing application in the transport sector. Disadvantages include high torque ripple and the complexity of designing and controlling them. Advances in theory, computer design, and control electronics can overcome these issues.

Swarm intelligence is one of the fastest growing subfields of artificial intelligence and soft computing. This field includes multiple optimization algorithms to solve NP-hard problems for which conventional methods are not effective. It inspires researchers in engineering sciences to learn theories from nature and incorporate them.
