User applications that provides multimedia operations are designed for the Linux operating system.
A UHF RFID-Based System for Real-Time Production Monitoring and Tag Quality Control in the Textile Industry
(SAGE Publications Inc, 2026) Altuglu, Ogeday; Gunduzalp, Mustafa
In the textile industry, labeling errors during the production process present significant challenges for both quality control and product traceability. This study proposes a real-time RFID-based production tracking and label quality control system to address these issues. In the developed system, RFID tags attached to products are read by embedded devices equipped with RFID readers integrated into the production lines. The captured product code data is transmitted to a local server via MQTT. The server verifies the tags by querying a central database and provides instant feedback to the corresponding device. The system runs entirely over a local network and does not require an external internet connection, ensuring uninterrupted functionality even in infrastructure-limited environments. This architecture enables all devices on the production line to communicate synchronously with the server, maintaining system-wide consistency and integrity. In this way, the use of a single tag per product is ensured, and faulty tags are filtered out. Furthermore, the system evaluates tag readability to detect quality issues such as stitching errors, physical deformation and alerts the operator through feedback. As a result, defective products are identified and removed before production is completed, helping to reduce time loss, and improve overall production reliability.

Linux operating system is used in the design of the system. Device applications have been written using tools of Linux operating system. Developed applications take the geographical location information from the GPS module and transmits the information to a central server using the GSM module. In the study vehicle tracking power management GPS control and radio interface layer applications have been developed.
Fuel Tracking System for Trucks
(IEEE, 2019) Asligul Pala Baysak; Mustafa Gunduzalp; Gunduzalp, Mustafa; Baysak, Asligul Pala
In today's technology wireless communication devices with Bluetooth have started to take an important part of daily lives and is rapidly growing. At this point researches are made about the low power consumption of the devices fast and secure communication. Bluetooth Low Energy (BLE) ensures these requirements and is developing day by day to provide a low-energy and low-cost solution for the Internet of Things (IoT). Nowadays in-vehicle electronics technology is becoming essential with respect to customer needs. According to claim report results of one of the reputable automotive manufacturers indicates that the crucial expectation of prospects and customers is to have safety electronic systems and following up the status of the car remotely. Due to this reason consumer electronics and internet of things (IoT) technologies are depending on the assessment of needs. In order to follow up status of car remotely Bluetooth Low Energy technology (BLE) and acceleration sensors are widely used in vehicle electronics. In this study a prototype fuel level control system is implemented using wireless sensor networks via BLE. The fuel level sensor is placed into the fuel tank to collect the data at rest the vehicle in parked positon and engine off. Fuel levels are measured inside the fuel tank for the different scenarios. If an abrupt change occurs in the fuel level the users is informed via vehicle tracking system. The current work aims processing data locally transmitting via Bluetooth Low Energy and reporting the output data. The results/outputs of the system implementation are evaluated statistically with experimental design.

Implementation of ANN Training Module on Field Programmable Gate Arrays
(IEEE, 2019) Cagla Sarvan; Mustafa Gunduzalp; Gunduzalp, Mustafa; Sarvan, Cagla
This study provides an application-specific integrated circuit (ASIC) diagram of Artificial Neural Networks (ANN) with module design for 32-bit floating point operations on Field Programmable Gate Array (FPGA). It is aimed that ANNs train operations are moved from software to hardware and calculations are made by using IEEE 754 single precision floating point number format. The proposed architecture is designed with combination of Verilog and Very High Speed Integrated Circuits Hardware Description Language (VHDL). Sigmoidal non-linear function was used as the activation function of the train and look-up table (LUT) was created for process efficiency of the designed circuit. Natural parallelisms were used in the calculation of the operations which are implemented on FPGA thus the system operations was accelerated by performing independent operations during the same clock cycle. The results obtained from FPGA were compared with the results obtained from MATLAB R2016b.

Theoretical and experimental performance investigation of a two-axis solar tracker under the climatic condition of Denizli- Turkey
(WYDAWNICTWO SIGMA-NOT SP ZOO, 2012) Sinan Kivrak; Mustafa Gunduzalp; Furkan Dincer; Gunduzalp, Mustafa; Dincer, Furkan; Kivrak, Sinan
In this study an open-loop two axes movable photovoltaic (PV) solar tracker is designed and analyzed as detailed. Its performance over a fixed tilted (37 degrees) PV system is evaluated theoretically and experimentally for the climatic condition of Denizli Turkey. Two DC actuators motors are used for the movement of the solar tracker. In addition to the experimental data a computer program in Visual C#2005 that uses the equations for the solar radiation values of fixed and moving systems is developed. The performance difference of a fixed tilt PV panel and a two-axis moving PV panel was compared for months of May and June and it was found that the energy generation increases nearly 64% for tracking system when it is compared with fixed PV system. Moreover the performance improvement values for each month are obtained by using the developed and designed computer program.
Using Internal D Flip-Flops in FPGA as Alternative Memory
(Institute of Electrical and Electronics Engineers Inc., 2023) Bilge Deniz Maden; Mustafa Gündüzalp; Gunduzalp, Mustafa; Maden, Bilge Deniz
Field Programmable Gate Arrays (FPGAs) are used in various applications ranging from emulating older systems to modern complex digital systems by using the advantage of their very high speed and modularity. FPGAs utilize Block Random Access Memory (BRAM) and internal D flip-flops embedded within logic blocks as main memory. BRAM is used as general-purpose RAM whereas internal D flip-flops used as registers in many applications. In this study a system is designed to utilize internal D flip-flops as general-purpose RAM. Simulation and experimental results show that internal D flip-flops are being used as general-purpose RAM successfully by using designed control system that has some important key features. One of them is the combination of address bus and data bus which is achieved through storing address value within registers. The other one is stepping system. In this stepping system operations are realized through a rising edge of a single bit input. It takes three steps to complete a single operation. Read and write mode is selected through a bit which is controlled from outside of the FPGA device. Depending on mode bit the read or write operation is executed on second and third step. © 2023 Elsevier B.V. All rights reserved.
