Summary: This study investigated the influence of the observer's position in relation to the calculation surface, finding that different standards have varying considerations on the observer's position. Two types of calculations were conducted, with EN-13201 deemed to have a better approach but room for improvement in both standards. Additionally, the study highlighted the need for updates in RP-08 and BS-EN 13201 to make the observer's distance relative to the calculation surface a variable dependent on the stopping distance calculated based on the road's speed limit.

Summary: Small-sized non-synchronous islands with low system inertia will face the challenge of integrating more renewable energy sources, resulting in further reduction of inertia. Various methods, such as energy storage systems, distributed generation, and demand response, have been proposed to support inertia and frequency transients. This article investigates the possibility of regulating the power consumption of LED street lighting to provide frequency support in a system with reduced inertia. Tests integrating the simulation of an Italian small island's non-synchronous power system with the response of an actual LED street lamp are conducted in a Power Hardware-in-the-Loop testing environment. Both synthetic inertia and fast frequency response approaches are tested and discussed.

Summary: An energy efficient street lighting system is proposed in this paper to achieve a balance between energy savings and illumination utility. Each street light equipped with a sensor is divided into zones based on the distance to the nearest pedestrian or vehicle, and the illumination is adjusted accordingly. The street is divided into sections based on the average distance between lights, and the parameters for energy savings and utility are defined. Simulation results demonstrate the superiority of the proposed method over existing ones in terms of energy savings and utility.

Summary: Intelligent control of public lighting, involving a compromise between comfort, safety, and power consumption, is a challenging issue in smart city deployment. The proposed system uses presence sensors to detect pedestrians and adjust the light intensity of street lamps accordingly to provide a comfortable view of the street. The efficiency of the control system is evaluated using the ROC curve method to determine the optimal number of previous street lamps.

Summary: Near-Zero-Energy Buildings present challenges in various aspects of energy, but accessing affordable technological solutions remains difficult in developing countries. A low-cost and reliable home energy-management prototype was developed and implemented on a scale model, showcasing the optimization of energy consumption and savings through a PWM charge controller and battery storage management. The prototype's successful energy management system was then applied to a large-scale smart solar home, focusing on lighting management and achieving additional energy savings.

Summary: This article introduces a systematic approach for designing transmission-line canonical cross-coupled filters. By properly utilizing two types of standard building blocks (N-type and P-type), a filter schematic can be formulated from a coupling diagram with arbitrary sign combination of coupling coefficients. Practical filter schematics and their design formulas are presented. Instructions on how to use the design formulas in actual filter designs are provided. Design and implementation examples of two sixth-order filters are discussed for demonstration.

Summary: This paper introduces a hybrid cooperative spectrum sensing technique that utilizes the existing diversity between power line and wireless media to improve spectrum sensing functionalities in power line communication systems operating in the frequency band between 1.7 and 100 MHz. The performance evaluation of the proposed technique demonstrates that exploiting the diversity between signals acquired from both the electric power grid and air can greatly enhance the detection of spectrum occupancy or holes compared to using only one of them.

Summary: A bolometric thin-film-based transfer standard for absolute power detection in D-band (110-170 GHz) is presented. It utilizes a resonance-type matching technique with thin-film resistive lines, where the same line functions as the sensing element. The change in resistivity of the line under the incident wave is calibrated to measure absolute RF power in the D-band.
