    Software Technologies, Architectures and Interoperability in Remote Laboratories
    (2010) Özbek,M.E.; Kara,A.; Ataş,M.
    A remote laboratory aims to provide access to remote lab equipment over the internet. The design and development of the client software is subject to various requirements. In this paper we discuss these requirements and propose solutions. Implementations are demonstrated for some remote experiments developed in the ERRL project. An XML format for experimental results is proposed as an attempt towards standardization of remote laboratory interfaces and enhancing the interoperability of diverse remote laboratory applications. ©2010 IEEE.

    Design of a System Solution That Modernizes Legacy Supervisory Control and Data Acquisition Systems as an Early Detection System
    (Sage Publications Ltd, 2018) Demir, Besir; Tumay, Ahmet; Ozbek, Mehmet Efe; Cavus, Enver
    Background: In industrial disasters, early detection of problems and crisis management are critical for saving the lives of people and reducing the impact of disasters. Purpose: In this study, we design a special gateway system that bridges the gap between different communication protocols and enables legacy supervisory control and data acquisition systems to function early detection systems for potential industrial disasters. Methods: The system uses a new queue mechanism to substantially improve the problem of data loss found in conventional supervisory control and data acquisition systems and utilizes identification (ID) prioritization to enable early detection of problems. The proposed system is implemented and tested on a Linux-based, 3G-capable Modbus gateway system. Modbus is used as the communication protocol and 3G technology is utilized to provide high-speed wireless data transfer components. The Modbus gateway device uses an ARM-based EP9302 processor and has digital input/output, relay outputs, and RS485 outputs. Conclusion: This study is significant as it is the first work to show the application of the priority query execution method for Modbus gateway devices.

    Packet Header Classification for Network Intrusion Detection System Based on Fpga
    (Institute of Electrical and Electronics Engineers Inc., 2022) Dakhil,Y.H.; Ozbek,M.E.; Al-Kaseem,B.R.
    Network security is becoming a key problem in data communication via the Internet. Classifying the incoming packets on network devices is one of the ways that increases network se-curity. Packet header classification is a major strategy for secure networking and connectivity. An intrusion detection system (IDS) is necessary for network devices to protect the network's traffic. Packet classification is a mechanism used by Internet services and security tools to examine each incoming packet against predetermined rules. This paper introduces a new algorithm for packet header classification based on a field-programmable gate array (FPGA) using the finite state machine (FSM) technique. The introduced algorithm compares each header field of an incoming packet to a predefined rule stored in a block read-only memory (ROM) of the FPGA chip to identify matches and then executes certain snort rules to classify them. The selected FPGA platform in this work exhibited high processing speed, particularly in digital system design. The presented algorithm was written using Verilog programming language and executed in Xilinx Vivado 18.2 software. The final program was uploaded to the Artix-7 FPGA development board. The simulation results demonstrated that the developed algorithm successfully classified the incoming packets as required with a maximum throughput that reached 100 Mbps. © 2022 IEEE.

    Robust and Adaptive Control Design of a Drilling Rig During the Operating Modes
    (Sage Publications Ltd, 2019) Sadeghi, Amir Nobahar; Arikan, Kutluk Bilge; Ozbek, Mehmet Efe; Baranoglu, Besim; Nobahar Sadeghi, Amir
    Oil well drilling towers have different operating modes during a real operation, like drilling, tripping, and reaming. Each mode involves certain external disturbances and uncertainties. In this study, using the nonlinear model for the modes of the operation, robust and/or adaptive control systems are designed based on the models. These control strategies include five types of controllers: cascaded proportional-integral-derivative, active disturbance rejection controller, loop shaping, feedback error learning, and sliding mode controller. The study presents the design process of these controllers and evaluates the performances of the proposed control systems to track the reference signal and reject the uncertain forces including the parametric uncertainties and the external disturbances. This comparison is based on the mathematical performance measures and energy consumption. In addition, three architectures are presented to control the weight on bit during drilling process, and also to maintain a preset constant weight on bit, two control approaches are designed and presented.

    Modelling and Controlling of Drill String Stick Slip Vibrations in an Oil Well Drilling Rig
    (Elsevier, 2022) Sadeghi, Amir Noabahar; Arikan, Kutluk Bilge; Ozbek, Mehmet Efe; Noabahar Sadeghi, Amir
    Mitigating of drill string vibrations, plays a distinctive role in increase of rate of penetration and consequently decrease of the operation costs, prevent of severe damages to drill string and bit, increase of drilling operation quality and safety, and enhance the performances of the controllers. This study deals with modelling and controlling of drill string vibrations with focus on stick slip vibrations in vertical wells. The approach taken to subdivide the drill string into smaller torsional sections and model the complete system dynamically and employ the extracted torsional model to model the stick slip vibrations mathematically. To mitigate and or active control of stick slip vibrations, three architectures are developed and proposed, manipulation of the rotational speed, manipulation of the weight on bit, and increasing of the damping in the bottom of the drill string. The performance of each strategy is analysed individually as well as relative to each other, using a mathematical measure when the drill string length is divided into smaller torsional sections. By the aid of the simulations and mathematical measures, it is shown that manipulation of rotational speeds at the surface may not be an effective solution to reduce the stick slip vibrations, however manipulation of weight on bit and increasing of damping at the bottom of string can be two effective solutions to mitigate these kinds of vibrations. As a general conclusion, it is proved that the manipulation of bottom side drilling parameters is more effective than the manipulation of surface drilling parameters.
