Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control A bandwidth reconfigurable antenna for devices in low UWB-applications Subject The topic of the resource Band notched E-shaped slot PIN diode Switchable frequency Ultra-wideband Description An account of the resource A reconfigurable simple design planar antenna for ultra-wideband applications is proposed, with E-shaped slot contained four narrow vertical slots that has the capacity of switching using four PIN diodes with a ground plan and a microstrip power line. An additional circularly polarized (CP) band is obtained by changing the on/off states of the PIN diodes. Moreover, the four PIN diodes are attached in the middle of the E-shape slot and used to switch the radiation flow of the patch. For validation, a patch antenna design is offered, based on a distinctive situation analysis. The antenna offers the low-ultra-wideband (UWB) frequencies band. Therefore, the switch of the operating states of PIN diodes gives us a good bandwidth re-configurability. In addition, with this flexible configuration we achieve a good -10 dB bandwidths with the ability to change the bandwith ranges from narrow-band 2.3 GHz to wide-band 3.1 GHz. Also, we achieve a large band for 3 dB AR is 2.57 GHz.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control A novel Ethernet based processing system for remote source harmonic detection Subject The topic of the resource Embedded design techniques Ethernet FFT Harmonic distortion Lightweight IP Description An account of the resource This work is carried out to objectively establish a new method to detect harmonics and measure the total harmonic distortion (THD) in a remote source, such as a high voltage transformer. The proposed approach utilized embedded design techniques to construct an embedded processor system with Ethernet intellectual property core to acquire data from a remote harmonics source. The designed system has several notable merits, namely, it is portable that can be applied in the work field, and it avoids workers from being subject to a hazard high voltage shock as well as its simplicity and high accuracy. The harmonics detection and analysis are achieved by inserting a microcontroller system near the high voltage transformer to acquire the necessary data and transmit it to a remote embedded processor system that is used to detect and analyze the harmonics. The microcontroller and the processor systems are connected by a wide-area network (WAN) through Ethernet and transmission control protocol/internet protocol (TCP/IP) protocols. The processor system is accommodated to perform 128 points fast Fourier transform for harmonics detection. Matlab simulations are used to validate the results. It is found that the results match very accurately the simulation results with an error of less than 0.02%. Creator An entity primarily responsible for making the resource Mazin R. Khalil, Laith A.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control A survey on security and policy aspects of blockchain technology Subject The topic of the resource Bitcoin Cryptocurrency Digital mining Encryption Initial coin offerings Description An account of the resource This survey talks about the problem of security and privacy in the blockchain ecosystem which is currently a hot issue in the blockchain community. The survey intended to study this problem by considering different types of attacks in the blockchain network with respect to algorithms presented. After a preliminary literature review it seems that some focus has been given to study the first use case while, to the best of my knowledge, the second use case requires more attention when blockchain is applied to study it. The research is also interested in exploring the link between these two use cases to study the overall data ownership preserving accountable system which will be a novel contribution of this work. However, due to the subsequent government mandated secrecy around the implementation of data encryption standard (DES), and the distrust of the academic community because of this, a movement was spawned that put a premium on individual privacy and decentralized control. This movement brought together the top minds in encryption and spawned the technology we know of as blockchain today. This survey explores the genesis of encryption, its early adoption, and the government meddling which eventually spawned a movement which gave birth to the ideas behind blockchain.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Aircraft pitch control design using LQG controller based on genetic algorithm Subject The topic of the resource Aircraft Autopilot Genetic algorithm Longitudinal plane LQG controller Pitch control Description An account of the resource Designing a robust aircraft control system used to achieve a good tracking performance and stable dynamic behavior against working disturbances problem has attracted attention of control engineers. In this paper, a pitch angle control system for aircraft is designed utilizing liner quadratic Gaussian (LQG) optimal controller technique with a numerical tuning algorithm method in the longitudinal plane through cruising stage. Main design approach of LQG controller includes obtaining best weighting matrices values using trial and error method that consumes effort and takes more time, in addition, there is no guarantees to obtain optimum values for weighting matrices elements. In this research, genetic algorithm (GA) is used to optimize the state and control weighting matrices and determine best values for their elements. The proposed traditional and optimized LQG pitch controller schemes are implemented utilizing Matlab simulation tool and their performance are presented and compared based on transient and steady state performance parameters. The simulation results reveal the ability of the optimized GA_LQG controller to reject the effect of the noises in the aircraft system dynamic and achieve a good and stable tracking performance compared with that of the conventional LQG pitch control system.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control An optimum design of high sensitivity PMMA-coated FBG sensor for temperature measurement Subject The topic of the resource FBG coating FEM Optical sensor Sensitivity Description An account of the resource Fiber Bragg grating (FBG) with silica material has limitations in measuring mechanical quantities such as strain and temperature, this happens because silica fibers are easy to break at higher transverse or axial strains. This deficiency can be overcome in several ways, one of which is by coating the silica FBG with a coating material made of metal or polymer. In this research, the FBG sensor has been designed by poly methyl methacrylate (PMMA)-coated FBG and silica. The finite element method (FEM) is used to analyze the electric field distribution on the surface of PMMA coated FBG with a coating thickness of 20 μm. Furthermore, the sensitivity of each coated FBG as a temperature sensor was measured in the range of 25 °C to 85 °C using coupled mode theory (CMT). From the design and analysis of coated FBG, it was found that FBG coated with PMMA material had the highest sensitivity of 395.73pm/°C. However, the FBG sensor coated with silica material has a sensitivity of 13.73 pm/°C. the shift obtained is also linear along with the temperature of 25 °C to 85 °C.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control BBO tuned PI controller for the stability of TCP networks Subject The topic of the resource AQM BBO algorithm Congestion PI Controller TCP networks Description An account of the resource The congestion is the most important issue that effects on the performance of data transition over internet networks. One of the important techniques developed is active queue management (AQM) that prepares an efficient congestion control by reducing losing packets, queue size, and energy consumption. Therefore, AQM technique deemed as a base of many congestion control algorithms schemes. This work suggested the using of proportional integral (PI) controller as an AQM and then use an optimized control system such as biogeography-based optimization (BBO) with PI controller as (BBO-PI). The optimal control (BBO-PI) is characterized by access to design and fine-tuning of defining the shapes of the optimal parameters of PI controller. The BBO algorithm was implemented by using the mathematical system model by M-file/Matlab and Simulink. The simulation results showed the best performance for the transmission control protocol (TCP) network when compared the system with using the PI controller and using optimal control (BBO-PI), the ratio of enhancing the system with using of BBO-PI better than using a PI controller only in terms of rising time is 1.11, settling time is 2.85 and overshooting is 85%. Therefore, the proposed method was very fast and required few iterations.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Design and manufacturing of iris waveguide filters for satellite communication Subject The topic of the resource Bandwide Filter Insertion loss Rectangular waveguide iris Description An account of the resource We propose in this paper, two bandpass filters in waveguide technology having rectangular symmetrical discontinuities with a half-radius r, designed and operating respectively in the X-Band (9−11.5) GHz and C-Band (3.5−5.5) GHz. These filters consists of eight irises placed symmetrically respectively on standard rectangular waveguides WR90 and WR229 in which resonant irises are inserted. These irises are used to couple the sections very strongly in this filter, which allows the bandwidth to be increased and the matching to be controlled. The comparison between the numerical and electromagnetic results, which we obtained for the filters, constitutes a means of validation of computer simulation technology (CST) environment and Mician for the design of the other circuit elements in the various frequency bands. We observed excellent consistency between the simulation curves and those of the measurements.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Driving cycle development methods: case study in Malaysia Subject The topic of the resource Driving cycle Emissions Fuel consumption Hybrid Electric Vehicle Micro-trip Description An account of the resource Over the years, many models have been created to estimate pollution inventories and fuel usage. These models can be divided into two types: travel-based and fuel-based. One of the most used travel-based models for estimating emission inventories is driving cycles. It can be used for a variety of different things, such as establishing pollution regulations, traffic control, and calculating journey time. For these goals, researchers have previously attempted to use easily available, well-established driving cycles. In many ways, however, the local environment differs greatly from that of the driving cycle’s genesis. As a result, these cycles’ applications have failed to provide high-quality results. This research aims to analyse the various approaches utilised for driving cycle construction in various locations of Malaysia under varied operational situations.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Enhance iris segmentation method for person recognition based on image processing techniques Subject The topic of the resource Biometrics Canny edge detection Hough transform Iris recognition Iris segmentation Description An account of the resource The limitation of traditional iris recognition systems to process iris images captured in unconstraint environments is a breakthrough. Automatic iris recognition has to face unpredictable variations of iris images in real-world applications. For example, the most challenging problems are related to the severe noise effects that are inherent to these unconstrained iris recognition systems, varying illumination, obstruction of the upper or lower eyelids, the eyelash overlap with the iris region, specular highlights on pupils which come from a spot of light during captured the image, and decentralization of iris image which caused by the person’s gaze. Iris segmentation is one of the most important processes in iris recognition. Due to the different types of noise in the eye image, the segmentation result may be erroneous. To solve this problem, this paper develops an efficient iris segmentation algorithm using image processing techniques. Firstly, the outer boundary segmentation of the iris problem is solved. Then the pupil boundary is detected. Testes are done on the Chinese Academy of Sciences’ Institute of Automation (CASIA) database. Experimental results indicate that the proposed algorithm is efficient and effective in terms of iris segmentation and reduction of time processing. The accuracy results for both datasets (CASIA-V1 and V4) are 100% and 99.16 respectively. Creator An entity primarily responsible for making the resource Israa A. Hassan, Suhad A.
