Chemical Rings
The epoxidized group, also known as the oxirane group, can be considered as one of the most crucial rings in chemistry. Due to the high ring strain and the polarization of the C–O bond in this three-membered ring, several reactions can be carried out. One can see such a functional group as a crucial intermediate in fuels, polymers, materials, fine chemistry, etc.

Locomotion Assistive Devices
Locomotion assistive devices equipped with a microprocessor can potentially automatically adapt their behavior when the user is transitioning from one locomotion mode to another. Many developments in the field have come from machine learning driven controllers on locomotion assistive devices that recognize/predict the current locomotion mode or the upcoming one.

Baobab (Adansonia digitata L.)
Baobab (Adansonia digitata L.), which belongs to the Malvaceae family, is an indigenous African tree widespread in arid savannah regions of Madagascar, mainland Africa, the Arabian peninsula, and Australia, and it was once classified as the “lost crop” of Africa.

Molten Salt Energy Storage
One may apply a molten salt storage to core power plants in the energy system with renewable energy sources. The application allows to extend the range of the load of the core power plants and thus better respond to and compensate the fluctuations of the power supplied from the renewables. The application may include the steam turbines from power cycles where fossil fueled boilers were withdrawn. The integration of the core units, the older turbines and the molten salt storage requires a detailed analysis of the existing systems. The entry describes several suggestions for this application and shows the results of the numerical simulations of their operation.

Microgrid Cyber-Security
The study examines the existing approaches to address cyber-physical security from a microgrid perspective. the work on the smart grid application, in general, lacks approach intersections and is still being dealt with from separate domains in the research world. Using the microgrid model to carry out experiments on the cyber-physical security has plenty of practical justifications attributed to the important role it plays in paving the way towards smart grids, the microgrid’s context was mainly consulted owing to the relative simplicity in capturing and recording the interventions, either as an injected attack or control modification. Cybersecurity measures for energy systems still come as accessories and not as a built-in function. In particular, for most of the part, the electricity-related equipment that gets evolved at an exponential rate makes it extremely difficult for cyber defenses’ mechanisms to keep pace with this development in the absence of up-to-date standards and common market trends.

Power Electronics Converters for Electric Vehicle Auxiliaries
Electric vehicles (EVs) are expected to take over the transportation and mobility market over traditional internal combustion engine (ICE) vehicles soon. The internal power demands of EVs are expected to increase. The reason for this is to achieve a longer driving range for the EV and to provide the required power for the low-voltage (LV) network auxiliary loads. To illustrate, there are extra added sensors, cameras, and small actuating motors, especially for future autonomous vehicles. Therefore, a new electrical/electronic (E/E) architecture is required to convert the high-voltage (HV) traction battery voltage (e.g., 320–800 V DC) to the standard LV levels with high current ratings of 5 kW and more. This HV-LV DC-DC converter is known in the literature as an auxiliary power module (APM).

Cromemco Dazzler
Cromemco's Dazzler (or TV DAZZLER) is a graphics card for S-100 bus computers. Released in 1976, it is the first commercial color bit-mapped graphics card available for microcomputers. Multiple Dazzler cards could be installed in a single machine and synced together, a feature which could, with minor modification, be used to genlock. Genlocked Dazzler cards drove ColorGraphics Weather Systems displays that generated most of the weather imagery seen on US television in the early 1980s.

Piezoelectric Rotary Harvesters
Technologies of energy harvesting have been developed intensively since the beginning of the twenty-first century, presenting themselves as alternatives to traditional energy sources (for instance, batteries) for small-dimensional and low-power electronics. Batteries have numerous shortcomings connected, for example, with restricted service life and the necessity of periodic recharging/replacement that create significant problems for portative and remote devices and for power equipment. Environmental energy covers solar, thermal, and oscillation energy. By this, the vibration energy exists continuously around us due to the operation of numerous artificial structures and mechanisms. Different materials (including piezoelectrics) and conversion mechanisms can transform oscillation energy into electrical energy for use in many devices of energy harvesting. Piezoelectric transducers possessing electric mechanical coupling and demonstrating a high density of power in comparison with electromagnetic and electrostatic sensors are broadly applied for the generation of energy from different oscillation energy sources.

List of Intel Core I3 Microprocessors
The following is a list of Intel Core i3 brand microprocessors. These processors are designed with cheap price points, while still retaining the power of the Intel Core line. As such they (along with Intel's i5 series) are often found in laptops and low-end desktop computers.
