In this paper we describe a method of audio chord estimation than does not rely on any machine learning technique. We calculate a beat-synchronized spectrogram with high time and frequency resolution. The sequence of chroma vectors (CRP features based on constant-Q transform) obtained from spectrogram is smoothed using self-similarity matrix before the actual chord recognition. Binary chord tem...

An in-orbit experiment was launched to evaluate the performance of the spaceborne high precision fiber optic gyroscopes (FOG). The three-axis in-orbit data of the FOG were analyzed using wavelet analysis method. Features of low frequency period terms and glitch noise were demonstrated. In addition, a method to extract the random noise from the in-orbit data is proposed based on the first-order ...

To alleviate the enhanced frequency, duration, and intensity of drought as a consequence global warming, admixing drought-sensitive European beech (Fagus sylvatica L.) with deep rooting silver fir (Abies alba Mill.) has been proposed. However, information on performance admixtures seedlings these tree species at limited water availability so far not reported. In present study, we investigated s...

Wheat growth, development and yield are severely affected by a wide range of abiotic stresses, salt stress is vital increasing stress. Salicylic acid (SA) phenolic phytohormone involved in plant physiological processes. Hence, we have conducted an experiment to explore the roles exogenous SA mitigating two wheat genotypes. There were eight treatments comprising (i) control, (ii) 0.5 mM SA, (iii...

Plant-arbuscular mycorrhizal (AM) fungi association is one of the oldest symbiotic relationships between organisms. This relationship may be more important under stress conditions such as drought and can help host plant tolerate drought. study was conducted in 2016 2017 at Agricultural Research Farm Razi University, Kermanshah, Iran to evaluate effect AM (AMF) inoculation (with either Funnelifo...

This study was conducted in order to investigate the effect of drought stress and Azomite fertilizer on some physiological traits of two tomato (Lycopersicon esculentum M.) cultivars (izmir and Izabella). A randomized complete design with factorial arrangement with three replications was used. Treatments consisted of three levels of irrigation including FC (control), FC (mild drought stress), a...

Drought is one of the most harmful abiotic stresses in arid and semiarid regions, so, field experiments were performed to examine biochar impact (15 or 20 t ha−1) on soil properties, physiological, morphological, yield barley under drought conditions. Our results displayed that caused a remarkable decrease stem height leaf area. Additionally, relative water contents (RWC%), chlorophyll b concen...
