TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Similarity measurement on digital mammogram classification
Breast cancer is one of the dominant causes of death in the world.
Mammography is the standard for early detection of breast cancer.
In examining mammograms, the overall parenchyma pattern of the left and right breast was placed side by side for…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Application of a wireless apnea monitoring device for crisis alertness and sleep diagnosis
Over the past five decades, obstructive sleep apnea has been noted as a
prevalent symptom in adults with escalated health conditions like stroke, obesity, high blood pressure, cardiovascular complications and chronic kidney diseases; to mention but…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Secure transmission for uplink and downlink non-orthogonal multiple access system with imperfect channel state information
In this paper, we design a secure transmission scheme in uplink and downlink of non-orthogonal multiple access (NOMA) system. In this scenario, two pairs of base station-user can operate under the presence of eavesdropper. The relay plays an…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Brain tumor segmentation using multi-level Otsu thresholding and Chan-Vese active contour model
Research on brain tumor segmentation has been developed, ranging from threshold-based methods to the use of the deep learning algorithm. In this study, we proposed a region-based brain tumor segmentation method, namely the active contour model (ACM).…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Dorsal hand veins features extraction and recognition by correlation coefficient
One of the most convenient biometrics approaches for identifying a person is dorsal hand veins recognition. In recent years, the dorsal hand veins have acquired increasing attention because of its characteristics such as universal, unique, permanent,…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Statistical analysis for the pitch of mask-wearing Arabic speech
The study is a comparison between the statistical properties of pitch (F0) for mask-wearing speech and unmasked. The speakers are Arab, of different ages and genders. A robust algorithm for pitch tracking (RAPT) is used for estimating F0. The…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> A sink based data gathering technique by using clustering for wireless sensor networks
New advance and integrated technologies have changed the traditional
systems and convert these systems into more intelligent, feasible and cost effective systems. In all data communications domain, data gathering is one of the significant task…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Type-1 and type-2 fuzzy logic-based space vector modulation for two-level inverter fed induction motor
Two-level inverter control with type-1 and type-2 fuzzy logic-based space vector pulse-width modulation (PWM) method for induction motor drive (IMD) is presented in this paper. A new sampling time independent strategy with type-1 and type-2 fuzzy…

TELKOMNIKA Telecommunication, Computing, Electronics and Control <br /><br /> Automated brain tumor detection of MRI image based on hybrid image processing techniques
Primary challenges are the identification, segmentation, and extraction of the afflicted area from the scanning of magnetic resonance. However, it is a time-consuming and tiresome for clinical specialists. In this paper,
an automated brain tumor…
