Article Assessment of Artificial Lighting Conditions in Sunlight-Deprived Classrooms(Gazi Univ, Fac Engineering Architecture, 2025) Duyan, Fazila; Kaplan, ElifNumerous studies on classroom lighting emphasize a close and significant relationship between students' concentration, comprehension of course content, and the efficiency of activities such as drawing, writing, and practices, with the lighting conditions. In this context, it is particularly important to properly design both the physical and psychological effects of artificial lighting, especially in sunlight-deprived classrooms. This study examines the artificial lighting conditions of a classroom located in the basement of a university building, which has no visual connection to the outdoors. The classroom is utilized by students from the departments of Architecture, Interior Architecture, and Industrial Design. The study investigates the effects of current artificial lighting on students, focusing on aspects such as visual perception satisfaction, light colour, illuminance level, glare, and the temporal light modulation effect. To assess students' perception of the existing lighting conditions, an online questionnaire was administered, and a total of 104 students (65 female, 39 male) who had previous experience with the classroom participated in the study. Technical measurements of the existing luminaires were conducted, and the classroom was digitally modelled using the DIALux Evo lighting software. The collected data were analysed using the SPSS statistical analysis program. The findings of the study indicate that students perceived the artificial lighting conditions as inadequate in terms of visual comfort. Moreover, based on technical measurements, simulations, and user evaluations, it was determined that the existing luminaires caused glare and temporal light modulation effects, negatively affecting the classroom environment.Conference Object Sts: AI-Driven Smart Test Scenario Generation Tool(IEEE, 2025) Baglum, Cem; Yayan, UgurOne of the most critical steps in the software testing lifecycle, test scenario generation, reduces process efficiency due to its high time and resource requirements. As an innovative solution to this issue, the Smart Test Scenario Tool (STS) has been developed. Smart Test Scenario Tool (STS) enhances contextual accuracy and automation in test scenario generation by analyzing documents in xlsx, py, cpp, txt, and docx formats using large language models. This approach minimizes time loss, and the risk of errors encountered in traditional manual testing processes while transforming test procedures into a context-driven and systematic framework, offering an innovative contribution to the literature. Strengthened with a Streamlit interface, MongoDB-supported database management, and Ollama integration, the system enables the test scenario generation process, a critical component of the software testing cycle, to be conducted more efficiently and reliably. The validity of the study was confirmed through two distinct projects, the first implemented in Python and the second in C++.Conference Object Parametric Trigger Signal Generation With Microcontroller and Fpga Based Architectures(Ieee, 2019) Kazma, Coskun; Levent, Vecdi Emre; Aydin, NizamettinA new system to obtain information from the central nervous system has been developed. Our system consists of two main components. The first of these components is the machine, which is located on the index and middle finger tips, stimulating mechanoreceptors according to the test protocol. The other is a personal computer running a desktop software for the implementation of test protocols. The flow is as follows. The subjects are asked the question of the test protocol through the personal computer. The parameters are then transmitted to the embedded system board on the machine. The embedded system board takes step motors to apply the relevant test parameters. The desktop software expects the subject to answer the question using the right and/or the left mouse button of the computer mouse. After answering the relevant question, the test proceeds to the next step. According to the test protocol, the stimulation process of the mechanoreceptors located at the index and middle finger tips must start and terminate at the same time. From this perspective, the embedded system board with 3 18F46K22 PIC microcontrollers produces 2 square wave signals with different frequencies and amplitudes simultaneously. The embedded system card developed with the PIC microcontroller is also implemented on an FPGA. The system has also been tested on 24 blue- and white-collar employees and a significant result has been obtained.
