The paper presents the novel HF-GEN method for determining the characteristics of Electrical Appliance (EA) operating in the end-user environment. The method includes a measurement system that uses a pulse signal generator to improve the quality of EA identification. Its structure and the principles of operation are presented. A method for determining the characteristics of the current signals’ transients using the cross-correlation is described. Its result is the appliance signature with a set of features characterizing its state of operation. The quality of the obtained signature is evaluated in the standard classification task with the aim of identifying the particular appliance’s state based on the analysis of features by three independent algorithms. Experimental results for 15 EAs categories show the usefulness of the proposed approach.

Very Low Frequency

Teknologi akustik saat ini banyak digunakan untuk keperluan sarana navigasi, komunikasi, dan pendeteksian. Sinyal akustik dapat dideteksi dan dihasilkan oleh perangkat transducer electroacoustic. Perangkat untuk mengubah energi akustik menjadi energi listrik disebut hydrophones atau received transducer, dan untuk mengubah energi elektrik menjadi energi akustik disebut proyektor atau transmit transducer. Dalam penelitian ini dilakukan perancangan dan realisasi transmitter (Tx) sinyal akustik pada very low frequency (VLF) band untuk bawah air, terdiri dari pulse signal generator, power amplifier, dan transmit transducer. Berdasarkan hasil pengukuran dan pengujian transmitter (Tx): Tx mampu membangkitkan sinyal suara (gelombang akustik) pada rentang frekuensi 12.67 s.d 33.68 kHz; tanpa pelindung anti air mampu memancarkan gelombang akustik (suara) pada rentang frekuensi 13.16 s.d 21.38 kHz, dengan pelindung anti air mampu memancarkan gelombang akustik (suara) pada rentang frekuensi 12.69 s.d 20.75 kHz, dan mampu memancarkan gelombang akustik (suara) di dalam air pada rentang frekuensi 13.10 s.d 18.91 kHz.

AbstractIt is suggested that the outbursts of Periodic Comet Schwassmann-Wachmann 1 are triggered by impacts of interplanetary boulders on the surface of the comet’s nucleus. The existence of a cloud of such boulders in interplanetary space was predicted by Harwit (1967). We have used the hypothesis to calculate the characteristics of the outbursts – such as their mean rate, optically important dimensions of ejected debris, expansion velocity of the ejecta, maximum diameter of the expanding cloud before it fades out, and the magnitude of the accompanying orbital impulse – and found them reasonably consistent with observations, if the solid constituent of the comet is assumed in the form of a porous matrix of lowstrength meteoric material. A Monte Carlo method was applied to simulate the distributions of impacts, their directions and impact velocities.
