This paper proposes a robust TV advertisement search based on audio fingerprinting in real environments. To obtain prominent audio peak pairs against different types of distortions, an adaptive thresholding method based on a median filter and peak-picking update is applied. Using the prominent audio peak-pair hashing, the proposed audio fingerprinting algorithm improves the robustness of the TV advertisement...
In opto-mechatronic systems using electric signals to drive motion control systems integrated with optical components, the driving signal may include the unwanted frequency band, such as resonant frequencies and noise frequencies. It can affect the accuracy and the repeatability of final opto-mechatronic system, and finally results into serious damage to the system due to resonance phenomenon of the...
We explore methods for effectively extracting information from clinical narratives, which are captured in a public health consulting phone service called HealthLink. The currently available data consists of dialogues constructed by nurses while consulting patients on the phone. Since the data are interviews transcribed by nurses during phone conversations, they include a significant volume and variety...
In this paper, we proposed a new approach for image clustering to address the adverse effects of noise presented in the images. In particular, the concept of information gain has been incorporated into classical fuzzy c-means (FCM) algorithm in order to develop a robust clustering method. FCM is associated with high sensitivity to noise and produces non-homogenous clustering. To induce robustness...

In the lithium-ion batteries for an electric-drive vehicle, the cell balancing is required to enhance life time of batteries and to guarantee safety. In the vehicle-to-grid (V2G) system, batteries of electric-drive vehicle are more frequently charged or discharged, which increases probability of cell imbalance. Therefore, battery management system (BMS) with efficient cell balancing operation is necessary...
We demonstrate a cost effective broadcast signal transmission in a WDM-PON by using directly modulated mutually injected Fabry-Pérot laser diodes (MI F-P LDs) as a low noise broadband light source (BLS). This novel WDM source enables to transmit the 1.25-Gb/s/channel with 100 GHz channel spacing.
We investigate a filtering effect and its mitigation method in a WDM-PON based on ASE injection seeding. The pre-filter has optimum bandwidth as a function of the injection power for mitigation of the RIN degradation.
A harmonic noise frequency filtering (HNFF) LC voltage-controlled oscillator (VCO) is fabricated using asymmetric inductance tank (AIT) in InGaP/GaAs heterojunction bipolar transistor (HBT) monolithic microwave integrated circuit (MMIC) technology. In order to optimize phase noise, the AIT and HNFF techniques are presented. The proposed VCO exhibited the phase noise of −117.3 dBc/Hz and −129.96 dBc/Hz...

A versatile 30V analog CMOS process in a 0.18 μm technology node has been developed by using cost-effective and modular fashion. To reduce the thermal budget deep NWELL isolation is formed after CMOS well formation. The drain-extended (DE) CMOS from 7V to 30V shows very competitive trade-off performance between the breakdown voltage and the specific on-resistance. In addition, low 1/f noise of 5V...

In this paper, we propose clipping scheme and equalizer as methods to reduce the effects of impulsive noise and channel attenuation in power line communication (PLC) system. Clipping is cutting off amplitude of the received signal over threshold level without its phase change and the equalizer compensates effects of PLC channel. The performance is evaluated in terms of bit error rate (BER). From simulation...

In this paper, a new adaptive vector filtering method with low computational complexity for image sensor applications is presented. The alternation between the ASDDF and the AVMF in the dependence on the order-statistics theory reduces the computational complexity. In addition, the proposed method provides excellent detection of noisy pixels and removes both chromatic and achromatic noisy pixels.

This research proposes new system which finds the music by using Query-by-humming (QBH). For finding a stored music, the features of humming data are selected by using G.729 feature extractor. We normalize the extracted features by using mean-shifting, median filtering, average filtering and min-max scaling methods. Then the corresponding music is matched based on dynamic time warping (DTW) algorithm...
