Robotic Psychology
Although the contribution that social robots have made to healthcare is recognized, much less attention has been given to the role that social robots can play in a specific healthcare application domain, namely psychology-based interventions. Robotic psychology, or robopsychology, is a research field not yet fully exploited in regards to the study of compatibility between people and robotic creatures on multiple levels (i.e., sensory–motor, emotional, cognitive, and social). The proper use of social robots in the psychological field would exploit their potential even more, since relationality is a fundamental aspect for any intervention aimed at affecting people’s psychological dimensions.

Street Canyon
A street canyon (also known as an urban canyon) is a place where the street is flanked by buildings on both sides creating a canyon-like environment. Classic examples of these human-built canyons are made when streets separate dense blocks of structures, especially skyscrapers. These include the Magnificent Mile in Chicago, Toronto's Financial District, the Canyon of Heroes in Manhattan and Hong Kong's Kowloon and Central districts. Urban canyons affect various local conditions, including temperature, wind, air quality, and radio reception, including satellite navigation signals.

Fire Engine
A fire engine, also known in some places as a fire truck or fire lorry, is a road vehicle (usually a truck) that functions as a firefighting apparatus. The primary purposes of a fire engine include transporting firefighters to an incident as well as carrying equipment for firefighting operations. Some fire engines have specialised functions, such as wildfire suppression and aircraft rescue and firefighting, and may also carry equipment for technical rescue. Many fire engines are based on commercial vehicle chassis that are further upgraded and customised for firefighting requirements. They are normally fitted with sirens and emergency vehicle lighting, as well as communication equipment such as two-way radios and mobile computer technology. The terms fire engine and fire truck are often used interchangeably to a broad range of vehicles involved in firefighting; however, in some fire departments they refer to separate and specific types of vehicle.

Agricultural Electrostatic Spraying
Agricultural electrostatic spraying technology is superior to non-electrostatic spraying technology. Electrostatic droplets have better “adhesion, penetration, and encircling ability” in crops. Electrostatic spraying technology is used to charge droplets to induce an electric field on the surface of the crop leaves, thus adsorbing electrostatic droplets and achieving directional movement of the charged droplets.

Ultra-Low-Frequency Oscillation
One of the prominent problems faced with hydro-dominant power system is ultra-low-frequency oscillation (ULFO) with a frequency deviation of 0.1 Hz lower, which is caused by the negative damping of hydro generators. ULFO might lead to an oscillation of all generators with the same oscillation frequency, restricting consumption of hydropower renewable energy.

Cracking of Wireless Networks
Cracking a wireless network is defeating the security of a wireless local-area network (back-jack wireless LAN). A commonly used wireless LAN is a Wi-Fi network. Wireless LANs have inherent security weaknesses from which wired networks are exempt. Wireless cracking is an information network attack similar to a direct intrusion. Two frequent types of vulnerabilities in wireless LANs are those caused by poor configuration, and those caused by weak or flawed security protocols.

Grid Code Requirements in Ethiopia
Rapid integration of renewable energy into the electric grid has ramifications for grid management and planning. Therefore, system operators have formulated grid code requirements to ensure that the grid continues to operate in a secure, safe, and cost-effective manner. The current state of grid code in Ethiopia, as well as the need for it, is discussed here. It lays out the technological grid integration requirements, with a focus on small and microgrids, which are especially important for the integration of renewable.
