Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Performance of piezoelectric energy harvester with vortex- induced vibration and various bluff bodies Subject The topic of the resource Bluff body Energy harvester Piezoelectric Vortex Description An account of the resource Piezoelectric energy harvesters (PEHs) are a kind of energy harvester that generates electricity due to pressure or vibration. Vortex-induced vibration (VIV) is a method that utilized wind energy and bluff body to generate the vibration in PEH. The objective of this research was to study the output voltage that generates in different bluff bodies with various airflow velocities. Experimental and simulation have done in this study. Experimental used PEH that consists of piezoelectric bimorph and rectangular-trapezoid fin. Bluff bodies with various cross-sectional areas, namely rhombus, square, and triangle were set up in front of the PEH at a distance of 80 cm. The various air velocities are set up to 5, 7, and 9 m/s in the wind tunnel with a cross-section of 250 mm × 250 mm. The simulation used the finite element method in explore the fluid flow pattern. The rhombus cross-sectional bluff body can generate voltage with an average of 1.5 volts. It is more voltage generated than a square and triangle. A vortex is formed near the rhombus bluff body and generates pressure fluctuation in its wake region. This pressure fluctuation takes place until airflow hits and leads PEH to vibrate and generate the voltage.

Title A name given to the resource TELKOMNIKA Telecommunication, Computing, Electronics and Control One to many (new scheme for symmetric cryptography) Subject The topic of the resource Cryptanalyst One-to-many scheme Symmetric cryptography Description An account of the resource Symmetric cryptography will always produce the same ciphertext if the plaintext and the given key are the same repeatedly. This condition will make it easier for cryptanalysts to perform cryptanalysis. This research introduces a one-to-many cryptography scheme, which can produce different ciphertexts even if the input given is the same repeatedly. The one-to-many encryption scheme can produce several ciphertexts with differences of up to 50%. The avalanche effect test obtained an average of 52.20%, better than mod- ern cryptography Blowfish by 25.46% and 6% better than advanced encryption standard (AES). One-to-many can produce different n-ciphertexts, which will certainly make it more difficult for cryptanalysts to perform cryptanalysis and require n-times longer to break than other symmetric cryptography.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Performance improvements of a VLC system, in a V2X context, using a different multiplexing technique Subject The topic of the resource BER DS-OCDMA OOC V2V V2X Visible light communication WDM Description An account of the resource This paper scrutinizes visible light communication (VLC) employing hybrid optical time division multiplexing (OTDM) wavelength division multiplexing (WDM). It also demonstrates the simulation of VLC using the direct sequence optical code division multiple access (DS-OCDMA) system developed by OptiSystem-Matlab Co-simulation. The profits of WDM and OTDM capacities have been combined using two levels of freedom to build up of the system. The performances are demonstrated in the simulated findings of the bit error rate (BER) in relationship with the data rate and the number of users. First, the simulated results display the usefulness of the system. Then, the number of users has been significantly enhanced. Besides, the OCDMA functions by appointing a specific code to each user and could provide asynchronous and simultaneous access to numerous users. One drawback is multiple access interference (MAI). The use of very long code sequences is crucial in order to lessen this effect. Hence, very large bandwidths are essential. This study aims at demonstrating, through system simulation, the practicability of an all-optical conventional correlation receiver dedicated to a DS-OCDMA access network link. Again, OptiSystem has been used to realize our blocks.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Low-cost central monitor based personal computer with electrocardiogram and heart rate parameters via wireless XBee Pro Subject The topic of the resource Central monitor Electrocardiogram Heart rate Wireless XBee Pro Description An account of the resource Heart rate signals and electrocardiograms are crucial indicators of a person’s health, particularly for individuals in intensive care units (ICU). The goal of this study is to wirelessly use a central monitoring system to continually and in real-time monitor the electrocardiogram signal and heart rate. The result of this research is that a wireless system can transmit continuous, distant, and real-time electrocardiogram and heart rate readings. Two transmitters and two receivers were used to send the signal in real-time. Lead II was used to capture the electrocardiogram (ECG) data, which was then processed by a microprocessor to determine the heart rate in beats per minute. The XBee Pro wireless was then used to transmit the data to the monitor in the form of an electrocardiogram and heart rate signal. The results of the XBee wireless performance test with statistics for determining heart rate value revealed that there was no discernible difference in the average value at a distance of 8, 10, 25, and 30 meters (P-value > 0.05). According to the study’s findings, wireless transmission is feasible over a limited distance and in real-time. Hospitals can use a central monitor to implement this research.

Among these solutions, RISs are considered as hardware technology to improve performance of optical wireless communication systems. Performance evaluation of systems is affected by atmospheric attenuation, pointing errors and moderate to strong atmospheric turbulence channels for quadrature amplitude modulation (QAM) technique. Atmospheric turbulence channel from moderate to strong is modeled using gamma-gamma distribution. Several numerical results obtained the average symbol error rate (ASER) performance versus beam waist radius and signal to noise ratio for three value of pointing error displacement standard deviation. From the results, it is show that with RIS assisted can effectively improve the performance and link distance of the wireless communication systems.

Title A name given to the resource TELKOMNIKA Telecommunication Computing Electronics and Control Biomedical-named entity recognition using CUDA accelerated KNN algorithm Subject The topic of the resource BioNLP Graphics processing unit Machine learning Named entity recognition Natural language processing Description An account of the resource Biomedical named entity recognition (Bio-NER) is a highly complex and time-consuming research domain using natural language processing (NLP). It’s widely used in information retrieval, knowledge summarization, biomolecular event extraction, and discovery applications. This paper proposes a method for the recognition and classification of named entities in the biomedical domain using machine learning (ML) techniques. Support vector machine (SVM), decision trees (DT), K-nearest neighbor (KNN), and its kernel versions are used. However, recent advancements in programmable, massively parallel graphics processing units (GPU) hold promise in terms of increased computational capacity at a lower cost to address multi-dimensional data and time complexity. We implement a novel parallel version of KNN by porting the distance computation step on GPU using the compute unified device architecture (CUDA) and compare the performance of all the algorithms using the BioNLP/NLPBA 2004 corpus. Results demonstrate that CUDA-KNN takes full advantage of the GPU’s computational capacity and multi-leveled memory architecture, resulting in a 35× performance enhancement over the central processing unit (CPU). In a comparative study with existing research, the proposed model provides an option for a faster NER system for higher dimensionality and larger datasets as it offers balanced performance in terms of accuracy and speed-up, thus providing critical design insights into developing a robust BioNLP system.
