Откат групповых политик

Если вы накосячили с групповыми политиками так, что они не могут автоматически применить новую версию или откатиться к локальному варианту — закешированные политики можно найти в реестре

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\

Так же локальные файлы политик можно найти в %windir%\system32\GroupPolicy и %windir%\system32\GroupPolicyUser

You Must Manually Run PSCONFIG after Installing SharePoint 2010 Patches — The Official SBS Blog — Site Home — TechNet Blogs

Помогает, если у вас «Не удалось подключиться к службе поиска».

 

In order to update the SharePoint databases, you must manually run the PSconfig utility. To run the utility:

1. Open an Administrative command prompt.

2. Change directory to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN

3. Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures

Note: The Companyweb site will be inaccessible while the command is running. It is best to run the command after business hours. T

ГрафиКон’2012 :: 22-я Международная Конференция по Компьютерной Графике и Машинному Зрению 1-5 Октября в МГУ

ГрафиКон’2012 :: 22-я Международная Конференция по Компьютерной Графике и Машинному Зрению 1-5 Октября в МГУ

Call for participation

GraphiCon is a leading international conference on Computer Graphics, Computer Vision, Image and Video processing in Russia. The 22nd event will be hosted by Lomonosov Moscow State University on October 1-5, 2012.

GraphiCon is a single track meeting with oral and poster presentations and will include several keynote presentations and tutorials to be announced soon. GraphiCon’2012 will also include Young Scientist School and three workshops – Biometry, Medical Image Processing and Visualization.

Authors are invited to submit papers presenting previously unpublished work directly related to the key subjects of the conference. Submitted papers will be reviewed based on the criteria originality, soundness, presentation, and empirical evaluation. All papers will be doubly blind reviewed, normally by three members of the program committee. Papers can be submitted in English or Russian.

Extended versions of selected papers from the conference will be published in a special issue of LNCS Transactions on Computational Science.

2.2 Computing Caustics

Snell’s Law is not easy to code with this formulation, because it only imposes one restriction, making the computation of the refracted ray nontrivial. Assuming that the incident, transmitted, and surface normal rays are co-planar, a variety of coder-friendly formulas can be used, such as the one in Foley et al. 1996:

 \vec T = \vec N \left ( \frac{\eta_1}{\eta_2}\left( \vec E \cdot \vec N\right) \pm \sqrt {1+\left(\frac{\eta_1}{\eta_2}\right)^2\left(\left( \vec E \cdot \vec N \right )^2 -1 \right)}\right) + \frac{\eta_1}{\eta_2} \vec E

Here T is the transmitted ray, N is the surface normal, E is the incident ray, and \eta_1, \eta_2 are the indices of refraction.
