想起我去年9月也是weekday super twilight, at callippe preserve.
hole 1- 5 only 1 ok drive at #1, 其他基本driver 打不起来。
后来 #6 par 3 打了一个pure PW, 之后 driver 一直straight bomb。当时已经准备放弃driver, 没怎么刻意调整
可能pw, short iron helps with groove swing.
长干不容易帮助建立那种impact 时club head sqaure 的感觉。

10 vs. 25 celsius deg
driver carry 差大约10 yard.
10 yard for each 15 celsius deg.
如果driver 能70% 以上能有250+ carry 有不太偏的话, 打一般性的local course,
简直是different ball game.
如果一直有 "swing hard" 的话, 距离还是会提高, suddenly but over a long
period of time.
不需要swing hard each shot, 最佳的模式是保留一些max out full swing, say once or
twice a week. 10-20% full swing try max out power.
这对身体恢复和保持swing power都帮助。
我还是倾向于swing 用力, 身体太放松容易get sloppy, 失去sqaure club face 的
feeling, 保持身体适度的tension, 太强或太弱对我效果都不好。
用力主要是保持posture 稳定,lower... 阅读全帖

Nicklause Swing:
http://www.youtube.com/watch?feature=endscreen&NR=1&v=a1dRdpt5Q
从这个video可以看出Jack Nicklause和很多pro挥杆的差别。他down swing刚开始时
lag没有增加。如果看Ben Hogan的挥杆会发现他down swing开始时杆身滞后导致lag增
加,大部分pro都是这样的。而nicklause从一开始就是抡(throw)的动作,有人管这叫
early release. Mike Austin是这种swing的代表人物.我从初学时学Ben Hogan到后来
改成学Mike Austin完全是自己摸索。我觉得传统的swing中timing的要求较高,因为
impact时手腕flip很大,一旦timing不好容易hook或push.后来发现了mike austin的
throw的方法觉得很有道理。这种方法swing plane很陡,杆面一直保持sqaure,impact
时不需手腕flip,提高了稳定性。这种打法打的也很远,austin是long drive

来自主题: Golf版 - 讨论一个技术问题
我最近还有一简单的体会就是强调眼看的是两腿的重心位置而不是球, 越长的杆儿越
靠球后。这样可以强化torso rotate 帮助杆头sqaure 而不是刻意手上加动作。
shaking 的问题暂时解决。 其实道理早就知道, 可是我没去强调就全走了样。

A 'word square' is an NxN arrangement of letters which forms words
horizontally and vertically, such as these 5x5 examples:
heart
ember
abuse
resin
trend
Read a dictionary containing 5-letter words then print all
valid 5x5 word squares which can be made from those words.
A square is valid if it contains only words from the dictionary.

my 2 cents. don't know if it is rite.
1, the magnitude of the fundamental freq component of a squre wave has a pi/
2 relationship with the amplitude of the square wave, which means higher
conversion gain for square wave LO.
2, in current switching mixer like gilbert cell, sine LO will result in more
noise since the both of RF differential pair maybe on at some time so they
are not degenerated by the tail current source transistor controlled by the
LO. for sqaure wave LO, all the time, only one t... 阅读全帖

E{ Y(n) } can also use the pdf of (Y1, ..., Yn), and Y(n) is a function of (
Y1, ..., Yn). It's the change of variable theorem that you can find in most
Real Analysis books that guarantees this.
It's like if Xi IID~ N(0,1), say T = X1^2 + X2^2 + ... + Xn^2
E(T) can be calculated by both the normal density and chi-sqaure density.

X_t = F_t * X_t-1 + R.
Y_t = H_t * X_t
What's the best way for finding the online parameter?

A brute force solution. Let M be the length of minimum segment,
X be the first point, Y be the second.
Then M=min{X,Y,|Y-X|,1-X,1-Y}.
We can find the cdf and pdf of M by computing
P(M>t)=P(X>t,Y>t,|Y-X|>t,1-X>t,1-Y>t)
=1-6t+9t^2 (This can be obtained by drawing the lines of the constraints on
the unit sqaure)
and the pdf of M is simply 6-18t.
Taking expectation by integration, we get E(M)=1/9.

For most cases, what is the typical way to present the reuslt of a
regression analysis?
(1) Mostly, only present the value of R square. It is rare to present the
adjusted R square for most cases.
(2) Only present the adjusted R square. It is at least not worse than
presenting R square.
(3) Present R sqaure and adjusted R square. In most cases, both of them are
required.

来自主题: _GoldenrainClub版 - 湾区高价房开始放量下跌了(zz)

跟全国各地一样,湾区高价房在五月份的成交量也显著增加。这对买卖双方都是好
消息。卖方的房子终于有人买了,买方也终于看到房价更趋于“合理”了。
比如,Cupertino五月份共卖出36栋,比前几个月一个季度还多。除了有两栋有些
Overbid外,其余成交价都比出价低,平均低10%左右。其中有几个降得很Impressive:
一个出价1175K, 以848K成交。
一个出价1278K, 以1062K成交。
一个出价1300K, 以970K成交。
一个出价1848K, 以1450K成交。
曾经看过一个要价1190K的五年新的、2200 Sqaure Feet的推倒重建的房子,比市面上
同地区的要价1300K到1400K的房子各方面都好很多,感觉一定会有很多人抢着去
Overbid,结果也只是以 1170K成交。既然这个房才卖1170K,附近那些要价1400K,又
老又小的60年老房应该没办法卖了。
