LoRa, Sigfox, and Narrowband-Internet of Things (NB-IoT) are some of the long-distance, low-power wireless communication technologies developed in the recent past. The proposed system consists of mainly nodes and a gateway as the fundamental system architecture. Nodes only communicate with the gateway individually and the gateway communicates with...

Materials can be classified based on their physical and chemical properties. Strength and flexibility are two important properties of materials, and they vary according to the physical shape of the material. One of the emerging technologies in the design and manufacturing field is 3D printing technology and is used to build anything from small e...

Agriculture is the primary means of obtaining food for the world's population. With the increase in growth in the world population, the demand for food continues to grow, and the available cultivatable land and resources like water have a scarcity. To address these issues, the agricultural industry has seen significant developments in the recent pa...

Electroencephalography (EEG) is the process of observing the electrical activity of the brain. In recent years there has been an increase in the availability of low-cost EEG headsets in the consumer market. This study was conducted using such a device, the Emotiv Insight 5-channel EEG headset. The objective of this study is to visually stimulate th...

The focus of this work is on increasing the solar concentration ratio for Photovoltaic (PV) applications. In this work, the scattering patterns of particles with various shapes are computationally studied in the near field. The results are analyzed to develop models with high concentration ratios. Based on the results, our question: ``Which particl...
