发帖数: 7 | 2 Both the C# samples take a component as iiput parameter.
First sample:
public void SetComponent(Component component)
or second sample:
public Decorator(LibraryItem libraryItem)
There is no need to construct the component in the decorator. By definition
a decorator adds additional behavior to the component *object*, not the
class. So a decorator should always reference the constructed component.
There is no need for a decorator constructor that constructs the component. |

Tiny transistor breaks new limits
Thursday, 18 October, 2001, 14:03 GMT 15:03 UK
Bell Labs also built the first ever transistor in 1947
Scientists in the US may have paved the way towards working molecular
computers.
A group of researchers at Bell Labs have made tiny functioning transistors a
million times smaller than a grain of sand.
Making large quantities of the tiny components should be straightforward
because they self-assemble.

PCA做的事情是,比如找出r(比如,用来做volatility smile的常用r=3)个component,
which 能够最大化的描述原来的covariance.且这r个component mutually independent
.. 而每个component是原来的X1,...,X10的weighted sum.
那么,如果你的数据是10个股票500天的log return,那么你可以算出它们的sample

From the self-diagnose perspective, we can consider a kind of self-awareness:
the trace/log of interactions between components. In an autonomic computing
field, each component is an autonomic part, and exposes well-defined interface
to the outside of the world. In this world, only interaction(input/output or
stimulus/response) makes a component knows itself. For example, the component
