发帖数: 39 | 1 我运行R的时候遇到这样的errror message:
Error: cannot allocate vector of size 375000 Kb
可是我查我的memory size 是：
memory.limit(size = NA)
[1] 1610612736
这么大的memory,怎么还不够呢？ |

发帖数: 792 | 2 没有使用STL的情况下，有如下程序：
int *array = new int(1000000);
if (array == 0) cout<<"insufficient memory"<
for (...) //赋值
array[i] = 随机数;
但是当i=33790后，就出现segmentation fault,
试过多次总是在33790后出错。如果array换成double
则改为在33790/2 = 16895后出错。显然和memory size
有关系。
既然array pointer没有返回空值，说明内存申请到了，但是
为什么出错呢？是系统heap size不够还是什么别的原因？
ulimit -a 显示stack size 为(kbytes -s) 10240， 而
33790×4没有10240k大啊？man ulimit说单位是1024byte，
也不知道ulimit -a中显示的到底是byte呢还是kbyte。
反正试过‘ulimit -s 很大的数’ 也没区别。
另外，如果用 int array[1M]的话，可以运行，但是到3M左右
就又是segmen |

发帖数: 6806 | 3 no you can not get the array size if the array is function parameter. T[]
will be automatically converted to T* for function parameters.
theoretically, the size of array is a part the type. int [5] and int [3] are
different types. therefore it is impossible to get the size information at
runtime, if you don't know it at compile time. |

另一篇说训练到后来不应该缩小learning rate而是应该增大batch size。

发帖数: 493 | 6 Assuming that you are still referring to amsbook.cls,
do you want to get rid of the small caps in the caption
or do you really want a bigger font size?
The font size for the captions used by amsbook.cls is
the LaTeX default of \normalsize (i.e., amsbook.cls
doesn't change the font size for captions). If you want
to change this to something bigger (I suggest you don't
because your caption text will end up larger than the
regular text), add the following to the style file in my
previous post:

发帖数: 1663 | 10 我得到过和你差不多的size，有时略大些，average size is 300-350bp
因为上sequencer之前要作size selection （切胶纯化，200-400bp左右），所以我觉
得把DNA打到300bp左右应该还是可以测序的。
你不放心的话，可以先找个positive control region 来测一下你的ChIP DNA.再上

发信站: The unknown SPACE (Wed Jul 10 13:45:43 2002) WWW-POST
'Limit' gives the limitation on the machine, not the running code's stack
size. The reason I wanna know that is because once I use another larger set of
input data, I got a bus error(not sure about it), while use smaller set of
input data, no problem at all, the code runs smoothly.
Thank you.

180nm的工艺，process feature size应该是180nm， 也就是最小栅长（L），是吗？那
么database unit (DBU), manufacturing grid, 以及snapping grid 相应地应该怎么
设置？看GDSII文件里DBU设置在0.001um，为什么这么小？feature size是不是就是指
版图里允许画的最小的尺寸，小于这个就通不过DRC了？比如说，180nm的工艺，无论是
W还是连线长度都必须是180nm的整倍数，snapping grid必须是feature size的整倍数
？如果画个200nm的金属线实际做出来是200nm还是180nm? |

发帖数: 533 | 17 没有做过SAXS的。做过相变中小角光散射的处理。权且抛砖引玉：
和你不同的是没有取向问题。要particle size的话算法是这样的，按照中心开始不同
半径统计光强，然后plot一个光强I-对半径r的关系。
散射光强其实就是你实际particle的密度函数的Fourier变换。所以r其实就是你的
particle domain size的倒数(其实严格来说r空间是你的lab coordination的inverse
space)。然后你的光强其实等价于你的概率密度。比如说你最强I的那个r值，就是你的
数均particle size
考虑到你这个里面还有取向，所以可能稍微会复杂一点。但是应该原理一样。算法其实
不难，用matlab就能很容易的实现。
可以参考一下Omar或者Kittle的solid state physics的书。 |

发帖数: 1403 | 19 谢乐公式在这个size是无效的。所以不可以用来估算。用XRay的话只能用SAX加上
TEM得到的颗粒形状信息来拟合。 话说回来已经这么小的size了，再精确又有多大
差别呢？ 气体吸附一样要预估颗粒形状，这个小size的颗粒很难做到形状一致，
所以。。。。。。相比而言还是TEM最精确

发帖数: 121 | 21 I would like to see your reference about the
definition of NA. This definition is a little bit different from the
conventional one, and it uses the minimum spot size of the beam in the
medium. The actual spot size can be obtained using Fourier transform formula
given a beam size, the converging angle and the refractive index of the
medium. |

You didn't say what you want to estimate and what your requirements are.
the only things you have said are useful: total sample 820000, and normal
assumption, and you want a sample size.
what if I told you sample size of 10? Is it ok?
但这个并不是我最关注的，因为不管求什么的分布（student score, GDP, or blood
pressure), 只要我样本基本符合正态分布，我都可以standardize整体数据来求
minimum sample size, 但我不知道该用什么公式以及已知变量来求。

I was asked a question about sample size and I forgot how to answer it.
Here it is: suppose we want to predict market share of 5 products, what is
the minimal sample size we need so that the error is less than 1%?
I have never worried about sample size since we have billions of records...
But since the boss asked, I need to worry about it now...
Can anyone help me? Is this called the power analysis?
Thanks a lot! |

mean.

the three discs it comes on. Disc one weighed in at 5.0GB, disc two 5.8 and

Japanese PS3 version, which packs a total of 39.4GB on on Blu-ray, (
according to Digital Foundry), it’s merely have the size. What are the
reasons? There’s no need to worry.

Nutraplanet typically has the best price on the 90 serving size for $45.9 |
