Case Studies with the Contiki-NG Simulator to Design Strategies for Sensors' Communication Optimization in an IoT-Fog Ecosystem.

With the development of mobile communications and the Internet of Things (IoT), IoT devices have increased, allowing their application in numerous areas of Industry 4.0. Applications on IoT devices are time sensitive and require a low response time, making reducing latency in IoT networks an essential task.

Analysis of Spatially Distributed Data in Internet of Things in the Environmental Context.

The Internet of Things consists of "things" made up of small sensors and actuators capable of interacting with the environment. The combination of devices with sensor networks and Internet access enables the communication between the physical world and cyberspace, enabling the development of solutions to many real-world problems. However, most existing applications are dedicated to solving a specific problem using only private sensor networks, which limits the actual capacity of the Internet of Things.

Rotating sample holder without mechanical linkages.

A sample rotator which operates in applied magnetic fields is described. The design eliminates mechanical linkages by magnetically orienting a gimbal ring. Three mutually orthogonal coils mounted on the gimbal provide a magnetic moment which is aligned along the field direction.
