Your paper starts:
Judo Ron 74 - Defying Newton’s third law of action-reaction
The first principle of judo being “Seiryoku Zenyo” or the intelligent use of energy was crafted by
Jigoro Kano after considering an older expression used in Ju Jutsu which read “Ju Yoku go o
Seisu and which can be translated to “softness controls hardness” i
The founder of Judo explained his interpretation of the “JU” principle with the use of some
units of power or energy that reads along the following lines: When facing an opponent
possessing a power of 10 who is about to strike and if you only have a power value of 7 to face
him, you are sure to be overcome if you try to resist on equal footing. However, if one is able to
adjust, adapt or pull back, he will be able to momentarily deflect the impact produced in the
direction of the attack. Soon thereafter, if one combines the incoming force with his own, then,
it will be possible to overcome the attack, make the aggressor lose his balance and defeat him
with the application of a selected technique. This is somewhat a simple statement, yet, it
encloses many physical factors worth studying.

I'll let someone else tackle that.
Later in the paper there is a graphic as below and the explanation below that:
能柔制剛
Technique overcomes power
。。。。。
I have no idea what sources you found, but the above four character saying is out of sequence, and the translation / explanation is not correct. While the best translation is always subject to discussion because of the complex, multiple meanings of Chinese characters, I hold it should read:
柔能制剛
The quality of flexibility/softness overcomes stiffness/hardness
but while there are many more, the terms 'technique' and 'power' do not appear. In Japanese, it is usually rendered 柔よく剛を制す.
My avatar is actually an extract from an ancient text of the relative portion, the Upper or High Strategy (上略) of the Three Strategies of Huang Shi Gong's Three Strategies (Master Yellow Stone's Three Strategies - simplified and traditional Chinese: 黄石公三略 pinyin: Huáng Shígōng Sān Lüè), considered one of the oldest recorded tactical theory guides.
There was a lot of information about this in the old forum; it might be useful to track it down if possible.
