1. Sense data is the direct result from
people’s sensation such as sound, color, harnesses and so on. Russell used
these terms to check whether the physical object, which is separated from
human’s sensation, independently exists and find what the real subject’s nature
is exactly like.
2. Proposition is the description of
objects in logicism. It is the statement answered by ‘True’ or ‘False’ and all
about object. One proposition can be stated in different way.
Statement of fact is in declarative sentence
in utterance. Not only word, statement can be in form of picture, formula and
so on. One statement of fact must be based on the other.
Propositions, statement of facts and verbal
expression has many differences. Usually one verbal expression can be constructed
by many propositions or statement of facts. About the subject of statement,
proposition and statement, what ever the subject changed, the meaning of
statement or proposition is stable. However, it will always changed when
different people use the same verbal expressions.
3. The thing that own specific
characteristics can be concerned as definite description, which Russell called
it 'the so-and-so'. When we get knowledge of things by definite description, we
may at the same time get something about the truth. Although we don’t know 'the
so-and-so', we know his or her existence.
Definite description is of high value
because it allows people get to know something without the help of truths that
is hard to find.
4. Chapter 13 is about how we can know what
is true and what is false.
Russell’s definition of knowledge is
something that is validly deduced when basing on known premises. During that
procedure, valid logical connexion as well as the ultimate premises should be self-evident.
Also the coherence can often work as a criterion. When dealing with complex
fact, people should treat it as a whole without desperate it into different
parts.
Chapter 14 describes metaphysics is not the
truth. When acquainting something, people do not need its relation and when
acquainting something’s relationship, people do not need to know all relations and
its nature. Secondly, about all existent knowledge, it is limited by what
people can get to know but not what comes from experience. Finally, when facing
different theories people should not deny them totally but find the correct
part.
I found a high quality research that is
also related to media technology named Unequal Protection of Video Data
According to Slice Relevance. It was published in 2011 and its 2010 SCI impact
factor is 2.60.
The authors devoted to create method on protecting
the video data more efficiently according to various net conditions as well as
the video importance. Precisely, they use procedure to firstly classify net
environments and the degree of importance that affect video quality to
different extents. Then algorithms are created respectively to replay video
with different but graceful degradation of the video quality, which forms the hierarchy.
The train of thought in this paper is clear
to follow. The main algorithm of Unequal Protection named Proposed Concealment
Driven Slice Reordering Algorithm is showed and the authors stated several
impact factor. Later, they use experimental ways on different kinds of
non-progressive video stream to put theory into practice. The subsequent researches are described at
last.
It is of profound meaning for this research.
As the number of source of video online is increasing overwhelmingly and the
quality is quite different, it is necessary to enhance the tolerance of
transiting video through Internet by prolife the efficiency.
