This study investigates the performance and efficiency of a perovskite solar cell through numerical simulation. The main objective is to evaluate the electrical characteristics of the device and to determine the key parameters affecting its photovoltaic efficiency. A perovskite-based solar cell structure was modeled by defining the electrical and optical properties of the absorber layer,...

Transformer overloading in densely populated urban distribution networks is a critical challenge during peak consumption hours. While traditional Flexible AC Transmission Systems (FACTS) are cost-prohibitive, Continuously Variable Series Reactors (CVSRs) offer a highly economical alternative (approximately $10/kVAr) by regulating transformer reactance—up to a maximum of 3 Ohm—via magnetic core...

Using rainwater as an alternative water source requires treatment approaches that reduce pollutants under real environmental conditions. In this study, a sensor-controlled treatment system based on a poly(vinyl alcohol) (PVA) nanofiber membrane doped with nut husk-derived activated carbon (NHAC) was developed to remove metals from actual rainwater and was operated in the field during rainfall...

Metal-semiconductor-metal (MSM) photodetectors are strong candidates for high-speed optical receivers and ultraviolet sensing owing to their planar structure, single-step lithographic fabrication, low capacitance and compatibility with field-effect transistor technology. However, MSM performance depends not only on the absorber material but also on the electrode geometry and the physics of the...

Multiservice software-defined networks (SDNs) must deliver multimedia traffic with different service requirements while maintaining acceptable delays and efficient use of limited channel capacity. This study addresses the challenge of distributing traffic flows when transmission patterns are variable and self-similar, making timely delivery difficult to assess. We develop a stochastic...

This study examined software projects completed and presented in the Computer Programming program of a vocational school in terms of the problems they addressed, their target users, and their artificial intelligence functions. This descriptive document analysis evaluated the final reports of 29 software projects deemed suitable for examination. The reports were classified by problem domain,...

In this study, Ground Penetrating Radar (GPR) was used to investigate continuous water discharge approximately 3 m below a retaining wall and assess possible leakage from a buried main wastewater pipeline or its building connections. Nine profiles (Lines 34–42) were acquired approximately parallel to the pipeline, and eleven profiles (Lines 49–59) approximately perpendicular to it at 0.30 m...

In modern video surveillance systems, the large area under observation and the varying distances of objects from the camera may reduce the informational value of the captured images. In particular, small and distant objects are represented by a limited number of pixels within the camera frame, making their detection and subsequent analysis more difficult. To address this problem, instead of...

Motion capture systems enable ergonomic risks to be assessed based on actual working conditions by recording operators’ movements during work. This study aimed to ergonomically improve a workstation where repetitive assembly operations are performed. First, a standard workstation was established, and operator movements were recorded using the Xsens system and transferred to the Siemens Process...
