Abstract:Â With the advent of Solid State Lighting came a renewed interest in the study of flicker. Potential effects include brightness enhancement, but also discomfort, ocular fatigue, phantom and stroboscopic effects. Both IEEE and IEC developed new metrics, but at the time of writing no firm consensus has been reached. Yet previous lamp studies in the Laplace laboratory showed that various flicker phenomenon are present on different lamps, but this feature is not documented. This paper focus on flicker changes w.r.t. applied voltage. The Indonesian power grid network is indeed characterized by large voltage variations; our purpose is to detect which lamps may exhibit too elevated flicker levels during out of nominal excursion and map such behavior with other electrical characteristics.

ABSTRACT: At the dawn of the fourth industrial revolution, we are witnessing a fast and widespread adoption of artificial intelligence (AI) in our daily life, which contributes to accelerating the shift towards a more algorithmic society. However, even with such unprecedented advancements, a key impediment to the use of AI-based systems is that they often lack transparency. Indeed, the black-box nature of these systems allows powerful predictions, but it cannot be directly explained. This issue has triggered a new debate on explainable AI (XAI). A research field holds substantial promise for improving trust and transparency of AI-based systems. It is recognized as the sine qua non for AI to continue making steady progress without disruption. This survey provides an entry point for interested researchers and practitioners to learn key aspects of the young and rapidly growing body of research related to XAI. Through the lens of the literature, we review the existing approaches regarding the topic, discuss trends surrounding its sphere, and present major research trajectories.

Thunderstorm | Shelter (Building: 30/30 Rule)
The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:
It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.
There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.
Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.
Today we examine relatively recent transactions in electrotechnologies — power, information and communication technology — that are present (and usually required) in patient care settings.  At a patient’s bedside in a hospital or healthcare setting, various electrical loads or devices may be present to provide medical care, monitoring, and comfort. Some of the common electrical loads found at a patient’s bedside include:
Hospital Bed: Electric hospital beds allow for adjustments in height, head position, and leg position to provide patient comfort and facilitate medical procedures.
Patient Monitor: These monitors display vital signs such as heart rate, blood pressure, oxygen saturation, and respiratory rate, helping healthcare professionals keep track of the patient’s condition.
Infusion Pumps: These devices administer medications, fluids, and nutrients intravenously at a controlled rate.
Ventilators: Mechanical ventilators provide respiratory support to patients who have difficulty breathing on their own.
Pulse Oximeter: This non-invasive device measures the oxygen saturation level in the patient’s blood.
Electrocardiogram (ECG/EKG) Machine: It records the electrical activity of the heart and is used to diagnose cardiac conditions.
Enteral Feeding Pump: Used to deliver liquid nutrition to patients who cannot take food by mouth.
Suction Machine: It assists in removing secretions from the patient’s airway.
IV Poles: To hold and support intravenous fluid bags and tubing.
Warming Devices: Devices like warming blankets or warm air blowers are used to maintain the patient’s body temperature during surgery or recovery.
Patient Call Button: A simple push-button that allows patients to call for assistance from the nursing staff.
Overbed Tables: A movable table that allows patients to eat, read, or use personal items comfortably.
Reading Lights: Bedside lights that allow patients to read or perform tasks without disturbing others.
Television and Entertainment Devices: To provide entertainment and alleviate boredom during the patient’s stay.
Charging Outlets: Electrical outlets to charge personal electronic devices like smartphones, tablets, and laptops.
It’s important to note that the specific devices and equipment present at a patient’s bedside may vary depending on the level of care required and the hospital’s equipment standards. Additionally, strict safety measures and electrical grounding are essential to ensure patient safety when using electrical devices in a healthcare setting. Â
We have been tracking the back-and-forth on proposals, considerations, adoption and rejections in the 3-year revision cycles of the 2023 National Electrical Code and the2021 Healthcare Facilities Code. We will use the documents linked below as a starting point for discussion; and possible action:

IEEE Education & Healthcare Facility Electrotechnology
There are many other organizations involved in this very large domain — about 20 percent of the US Gross Domestic Product.
Ahead of the September 7th deadline for new proposals for Article 517 for the 2026 National Electrical Code we will examine their influence in other sessions; specifically in our Health 100,200,300 and 400 colloquia. See our CALENDAR for the next online meeting; open to everyone.
Plug Load Management: Department of Energy By the National Renewable Energy Laboratory
How does the electrical grid respond to a crisis?
If the power goes out after a thunderstorm, utility crews are on the job within hours to restore service and get the lights back on. Most electric utilities in the U.S. have a reputation for reliability and recovery from situations like this. It has been noticed as planners began thinking about increased natural disasters brought on by population migration patterns, manmade interference due to malicious cyber-attacks, and the instability brought about by adding large quantities of renewable energy.
At North Carolina State University, The Future Renewable Electric Energy Delivery and Management (FREEDOM) Systems Engineering Research Center was created through funding from the National Science Foundation in 2008 to modernize the electrical grid to accommodate sustainable energy, such as wind and solar power. The Freedom Center has been involved in developing online tools for assessing vulnerabilities to address cyber-physical security called distributed grid intelligence. The hope is that smart microgrids with sensors embedded throughout the system might be more resilient to failure and easier to bring back online and large multi-state electric grids. But the emerging smart grid, together with distributed renewable energy such as rooftop solar, presents a new set of challenges to resilience. The Smart Grid involves more distributed energy down to the home level. That kind of penetration adds a level of vulnerability to a cyber threat. Engineers will certainly have to pay attention to that as the grid gets smarter.
Sporty weather season in the United States inspires a revisit of best practice for designing, building and maintaining the systems that provide limited electricity when the primary source fails. We have been active in the development of this and related titles for decades and have presented several proposals to the technical committee. Public response on the Second Draft of the 2025 revision will be received until March 27, 2024.
