Simulasi Penggunaan Frekuensi Milimeter Wave Untuk Akses Komunikasi Jaringn 5G Indoor

Milimeter Wave (mmWave) is a solution to overcome of frequency limitations in 5G technology implementations using high frequency carrier domain. This research discusses about mmWave frequency selection for 5G technology using empirical methods for indoor propagation model. Several mmWave frequencies are simulated on indoor office environment. Based on simulation with Indoor Hotspot (InH) placed...

Risk - based Maintenance Optimization for Transmission Equipment

This paper describes a new maintenance selection and scheduling approach for bulk transmission equipment that is based on the cumulative long-term risk caused by failure of each piece of equipment. This approach not only accounts for equipment failure probability and equipment damage, as do reliability centered maintenance (RCM) approaches, but it also accounts for the outage consequence in ter...

Precision Ultrasonic Wave Measurements With Simple Equipment

We describe the design and construction of a relatively simple, inexpensive laser interferometer system for accurate measurements of ultrasonic surface displacement waveforms in reasonably friendly environments. We show how analysis of a single waveform can provide both the calibration constant required for absolute measurements and an estimate of the uncertainty of these measurements. We demon...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
