Steady State Behaviour

Brushless drives are important, but are often thought to be difficult to treat quantitatively at the undergraduate level. The Blondel circle diagram is shown to be ideal for illuminating the steady-state behaviour and limitations of small brushless system, at a level suitable for undergraduate courses.

Power Testing

Throughout the last few years there has been a significant push to develop a means for the transmission of electrical power through solid metallic walls using ultrasonic means. The bulk of this effort has been focused on using two coaxially aligned piezoelectric transducers on opposite sides of a thick metallic transmission barrier, where one transducer serves as the “transmit” transducer and the other as the “receive” transducer. Previous modeling has predicted reasonably high power transfer efficiencies through the wall using this type of “acoustic-electric channel” to be possible at low power levels, which implies that channel component operates in a linear range with little concern of failure. High-power testing of two acoustic-electric channels has been done in an effort to determine power limits on such channels and to determine levels at which non-linear effects on the piezoelectrics become non-negligible. The tested channels are characterized by the “power density” imposed on the transmit transducer, that is, the power applied per unit area, as the values found for maximum power density are considered to be independent of transducer radii. The constructed channels are shown to be capable of transmitting large amounts of power (over 100 watts) without failure; and further, extrapolation of the results to channels with larger diameter transducers predicts power transfer of 1 kW to be highly feasible.

Artificial World

The visual system evolved and develops to process the scenes, faces, and objects of the natural world, but people adapt this powerful system to process data within an artificial world of visualizations. To extract patterns in data from these artificial displays, viewers appear to use at least three perceptual tools, including a tool that extracts global statistics, one that extracts shapes within the data, and one that produces sentence-like comparisons. A better understanding of the power, limits, and deployment of these tools would lead to better guidelines for designing effective data displays.

The research aims to analyze the power and limit of the state and whether Indonesia has properly adopted the concept of powers and limits during state emergency of COVID-19 pandemic. The method of the research was normative legal research which used statute and case approach were employed for data analysis. The result shows that a state may apply some types of power in an emergency condition. However, in using its powers, the government must consider principle of limits in a state of emergency. In fact, Indonesia does not properly adopt the balance of power and limit in the state of emergency during COVID-19 pandemic. It is true that the government may take actions to respond to the COVID-19 pandemic. However, the State cannot exceed the limitations of using powers in accordance with state emergency principle. There was a tendency to exceed the limits by the State during the pandemic. The State has violated some state of emergency principles during COVID-19 pandemic such as temporary, the rule of law, necessity, proportionally, intangibility, constitutionalism, harmony, and supervision. The research recommends that the Government and the House of Representatives (the DPR) in the future should obey the state of emergency principles, particularly in terms of state power limits to respect constitutional principles and rule of law. In addition, individuals, groups of people, or organizations may submit judicial review of laws or regulations that violate the state of emergency principles in handling pandemic in the light of protecting the fundamental rights of citizens.
