发帖数: 2123 | 1 The inverted yield curve has set off alarm bells that a recession may loom
around the corner. Historically, that's been a good bet, and recessions
almost always unleash bear markets for the Dow Jones, S&P 500 and Nasdaq.
But this yield-curve inversion, which may be short-lived, looks different.
While it raises some concern about the long-term economic outlook, the
recent inverted yield curve actually is welcome in the near term.

发帖数: 2123 | 2 For stock market investors, an inverted yield curve is a sign that equities
could peak before an economic recession hits. It also can be a precursor to
a bear market in stocks, where equities fall 20% or more from highs.
While an inverted yield curve has been a reliable indicator of slowing U.S.
economies, the timing of an upcoming recession has been uncertain.
Historically, prolonged "curve inversions" have usually preceded major
economic slowdowns by about a year.

发帖数: 83 | 5 inverter中width ratio是由switching point决定的吧，
也就是一般情况希望在输入为Vdd/2时，输出也为一半
此时经过pmos和nmos电流相同
beta_n/2*(Vsp-Vthn)^2=beta_p/2*(Vdd-Vsp-Vthp)^2;
Vsp = Vdd/2;
设Kpn=3Kpp,得Wp=3Wn
如果switching point不在中点，比如过高4/5Vdd，如果信号在Vdd，刚下降Vdd/5，
inverter已经工作，如果信号在GND，要让输入到达4/5Vdd，inverter才工作
baker的书有很好解释

4年的dell latitude D800， 最近开始罢工了，显示器变得很暗，基本什么看不见（模

今天中午拿学校的投影仪试的时候，奇怪的是当时显示器又没问题了。 但到了下午又
不能用了。 刚才找了个修电脑的问了一下，说是backlight/inverter要换了，要150块
钱。
大虾给点建议，是自己买配件diy修，还是干脆再买个新电脑得了。自己换现实不现实？
大概预算多少？ 值不值得修？
如果超过6，70的话，就不修了。

parallel indices and doclist pruning/merging?
I read a few materials: Introduction to Information retrieval, Larry Page
and Sergey's "anatomy of a search engine", and a paper :"Pruning Policies
for Two-Tiered Inverted Index
with Correctness Guarantee", which talks about pruning, but not about
parallel indices .

发帖数: 33 | 44 Most aircrafts use EmPower system, you need to purchase a special adaptor to
connect to the power and your cigarette lighter type inverter.
Note different airline uses different system, although EmPower is the most
popular one. AA uses cigarette lighter type of connector; some Singapore or
Northwest airline airbus have 110V AC connector.
You need to request the seat with power supply while checkin. To check power
supply location, you can go to http://www.seatguru.com
Good luck! |
