Abstract(J)筆者らは、マイクロホンで測定したエンジン放射音から、ノッキング音と筒内圧力に重畳したノッキング成分を推定する深層学習モデルを開発し、このモデルを用いたノッキング検知手法を提案してきた。本報ではノッキング音の大きさの評価を目的とし、エンジン放射音からノッキング音を分離する改良モデルを提案する。

Abstract(E)The deep learning model we developed estimates knocking sound pressure and knocking component superimposed on in-cylinder pressure from engine radiation noise measured by a microphone. This model obtains the time frequency mask and frequency response from many pair data of engine radiation noise and in-cylinder pressure. The time frequency mask extracts the knocking sound from engine radiation noise. The frequency response converts the extracted knocking sound into the knocking component superimposed on in-cylinder pressure. We propose an improved model to separate the knocking sound from the engine radiated sound in order to evaluate the magnitude of the knocking sound.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
