Flying Disc Techniques
Flying discs (including Frisbees) can be thrown in many ways. Each throw involves snapping the wrist as well as flicking the arm to impart gyroscopic stability to the disc and accelerate its mass to a certain velocity. Without spin, a disc will wobble and fall; without velocity, the disc will not go anywhere. Using these two guidelines, any number of throws are possible. Most discs are designed to create lift when thrown with the flat side up.

Emergency Communication Networks
Emergency communication refers to the communication means and methods needed for the extensive use of various communication resources to support rescues, including emergency rescues, and the necessary communication in the case of natural or manufactured emergencies. Because of the characteristics of disasters, making effective use of limited resources to provide the best communication services is a key problem. Unlike the traditional communication network, the emergency communication network is a complex network, and enables the implementation of emergency rescue activities and provides the primary conditions for the realization of emergency rescue functions. Its network structure has a significant impact on rescue efficiency. In different emergency situations, the demand for emergency communication is different, and the technical means used are different. Emergency communication mainly has the following characteristics: uncertainty of time and place; uncertainty of capacity demand; high degree of timeliness of the emergency communication; complexity of the environment; uncertainty of the degree of damage to the communication network itself; and diversification of information.

Deep Learning Based Non-Orthogonal Multiple Access
Non-Orthogonal Multiple Access (NOMA) has become a promising evolution with the emergence of fifth-generation (5G) and Beyond-5G (B5G) rollouts. The potentials of NOMA are to increase the number of users, the system’s capacity, massive connectivity, and enhance the spectrum and energy efficiency in future communication scenarios.

Froth Flotation
Froth flotation is an important operation for the recovery of valuable minerals in the mining industry. The essence of flotation processes lies in the interactions between particles and bubbles, which can be categorized into three successive sub-processes which are bubble-particle collision, attachment and detachment. These three sub-processes determine the overall performance of flotation processes for treating a particular ore.

TI MSP432
The MSP432 is a mixed-signal microcontroller family from Texas Instruments. It is based on a 32-bit ARM Cortex-M4F CPU, and extends their 16-bit MSP430 line, with a larger address space for code and data, and faster integer and floating point calculation than the MSP430. Like the MSP430, it has a number of built-in peripheral devices, and is designed for low power requirements.

Sensor Technologies for Transmission and Distribution Systems
Today sensors have become one of the most essential components of an outage management system in the electrical power grid. The real time monitoring capability of sensors helps in total prevention or reduce the impact of disruptions in the trans-mission and distribution networks. Sensors make condition-based maintenance of the power grid possible which can be cost effective and more efficient than the normal scheduled maintenance in certain cases. Sensors also form a very crucial input facing part for most control and monitoring systems as they are solely responsible for the raw fault data acquisition. Various grid parameters collected from the sensors are important for classification and forecasting purposes to provide better predictive, adaptive, and corrective analysis of the nature of functioning and breakdown of instruments in the transmission and distribution lines. Utilization of assets of the power grid is highly increased with the probabilistic risk assessment or contingency analyses using sensors.

5G Technology in Healthcare and Wearable Devices
Wearable devices with 5G technology are currently more ingrained in our daily lives, and they will now be a part of our bodies too. The requirement for personal health monitoring and preventive disease is increasing due to the predictable dramatic increase in the number of aging people. Technologies with 5G in wearables and healthcare can intensely reduce the cost of diagnosing and preventing diseases and saving patient lives.

Feasibility of thermal insulation for retrofitting Historic Walls
Retrofitting historic constructions can play a key role in reducing European energy consumption and consequent emissions. What is more, beyond the opportunity for tackling climate change, thermal retrofits can improve indoor comfort while lowering operational costs, factors that are fundamental to ensure the continued use of historic constructions over time, and with that, improving their preservation and durability. The suitability of thermal insulation for this scope is still a debated topic. Thus, this study aims at contributing to the discussion by providing an overview on the feasibility of adopting thermal insulation for retrofitting external walls of historic buildings while preserving their significance and unique identities.

Main Technological Challenges in Implementing Holographic-Type Communication
Holographic-type communication (HTC) permits new levels of engagement between remote users. It is anticipated that it will give a very immersive experience while enhancing the sense of spatial co-presence. In addition to the newly revealed advantages, however, stringent system requirements are imposed, such as multi-sensory and multi-dimensional data capture and reproduction, ultra-lightweight processing, ultra-low-latency transmission, realistic avatar embodiment conveying gestures and facial expressions, support for an arbitrary number of participants, etc.
