In this paper we propose a postprocessing technique for a spectrogram diffusion based harmonic/percussion decomposition algorithm. The proposed technique removes harmonic instrument leakages in the percussion enhanced outputs of the baseline algorithm. The technique uses median filtering and an adaptive detection of percussive segments in subbands followed by piecewise signal reconstruction usi...

Tungsten inert gas (TIG) welding, also called as gas tungsten welding 1. (a) Schematic of TIG welding Process (b) Variety of tungsten electrodes. The activated TIG (ATIG) welding process mainly focuses on increasing the depth of penetration and the reduction in the width of weld bead has not been paid. Tungsten inert gas welding, TIG is widely applied in manufacturing process for different The ...

Gas tungsten arc welding (GTAW) or Tungsten inert gas welding (TIG) is one of the widely used techniques for joining ferrous and non-ferrous metal.Gas tungsten arc welding process,consist of non-consumable tungsten electrode which is used to provide the arc for welding. During the welding cycle a shield of inert gas expels the air from the welding area and prevents oxidation of the electrode, w...

This paper provides a general introduction to welding fundamentals (section 2) followed by sections on a few selected welding processes that have had significant developments or improvements over the last few years. The processes that are discussed are friction welding (section 3), hot plate welding (section 4), ultrasonic welding (section 5), laser/IR welding (section 6), RF welding (section 7...

Automatic extraction of semantic music content descriptors has traditionally focused on melodic, rhythmic and harmonic aspects. In the present paper, we will present several music content descriptors that are related to percussion instrumentation. The “percussion index” estimates the amount of percussion that can be found in a music audio file and yields a (numerical or categorical) value that ...

This paper presents a method for voice percussion recognition and its application to drum pattern retrieval. Recognition of voice percussion (verbalized expression of drum sound by voice) requires an approach that is different from existing methods. Individual differences in both vocal characteristics and the kinds of verbal expressions used add further complication to the task. The approach ta...
