Can someone rectify this. Thanks in advance.  \textbf{Sub interval 1:}($t_{o}-t_{1}$)\\\ This sub-interval starts when D1 and D4 are Forward biased, so in this sub-interval D1-D4 and D6-D7 are conducting Bridge voltages $V_{h1}$, $V_{h2}$ and primary current $i_{r1}$ is as shown in waveform. This sub-interval ends when current is commuted from D6-D7 to S6-S7and from D1-D4 to S1-S4. Hence for ZVS operation of S1 and S4, primary current \fbox{ $i_{r}(t_{0})&lt;0$}.\\

What are Unity's keyboard and mouse shortcuts? In Unity, are there any pre-defined shortcuts, e.g. to open the dash or unhide the launcher? Word or expression for a constituent that perfectly exemplifies the whole Suppose that  (1990) is considered appalling, but you can't put your finger on exactly why, mainly because there are a plethora of reasons, most of which you lack the training/education/expertise to comment in-depth on (e.g. the writing, directing, editing etc.), so you use what you consider to be a disastrous moment/scene as an example, and think "this pretty much sums it up", for example , what would you call a scene like that? A single word or expression is satisfactory.  As an example:     "The Godfather 3 is so bad, for so many reasons, but here is a ______ that perfectly represents everything wrong with the movie."   An expression is also acceptable, and the example I gave is flexible (doesn't have to be structured as it is in the example). Software needed to scrape data from graph Anybody have any experience with software (preferably free, preferably open source) that will take an image of data plotted on cartesian coordinates (a standard, everyday plot) and extract the coordinates of the points plotted on the graph?  Essentially, this is a data-mining problem and a reverse data-visualization problem. Why are badges on per-site-metas separate? Badges earned on per-site meta sites are separate from the main site, but reputation is carried over from the main site (because you don't earn any on Meta).   I perfectly understand keeping the rep the way it is (meta votes are too subjective to integrate them with rep) but the badge split seems odd to me.  Multiple badges are in fact impossible on Meta; Mortarboard, Bounty related badges. In addition badges in general are much harder to earn due to the lower amount of users and content; badges like Great Answer are nearly impossible.   As a result of this, most users on Meta end up with the easy 5-10 bronze badges for basic participation on Meta and not much else; stuff like Supporter and Critic that are hard not to get.   I understand the want to drive more people to meta, so perhaps badges are separate to institute a reward system; however this doesn't seem to work well since Meta badges (mostly) don't appear on the main site. This in combination of the 0 rep gain makes Meta feel almost not real. It also makes part of your progress (badges) on the main site invisible on Meta, and vise versa.  IMO the badges should be the same on both Meta and main site, but more Meta-oriented badges should be added to encourage use of Meta. This way Meta badges feel "real" instead of "Meta".  Is there an official reason for per site metas having separate badges? Redirect parent window from an iframe action What JavaScript do I need to use to redirect a parent window from an iframe?

(udisks-error-quark, 0) resolv.conf not working properly with Ethernet in Ubuntu I have a Lenovo X200 laptop on which I am running Ubuntu 9.10. Recently, (I assume after some updating, but I really don't know) my ethernet port stopped working under Linux. A more tech/linux-savvy friend of mine was able to temporarily fix the problem by manually editing the resolv.conf file with the DNS servers he found through his connection. However, after rebooting, the problem came back and now I am looking for a more permanent solution. How to install Python 3.6? I'd like to install the latest Python, which is 3.6 at the time of this post. However, the repository is saying that Python 3.4.2 is the newest version.  I've tried:   $ sudo apt-get update $ sudo apt-get install python3  python3 is already the newest version.  $ python -V  Python 3.4.2   To upgrade to Python 3.6 on my Windows workstation, I simply downloaded an exe, clicked "next" a few times, and it's done. What's the proper and officially accepted procedure to install Python 3.6 on Debian Jessie? Bibtex true unsort Using continuous color band for raster legend in QGIS composer legend? I'm looking for a way to insert continuous colour legend for a raster layer.  I managed to create discrete symbols with values along the bar, but I would like to have a continuous bar with some values on the bar, similar to the old plugin "One-Band Raster", that it doesn't work with the QGIS version higher than 1.7  I tried to set in properties->style, where I selected the  Render Type "Singleband pseudocolor" and see the "generate new color ramp" box.  I tried both "Continuous" or "Equal interval". However, in the Composer the legend always is displayed with discrete symbols.  Is there any way that can make QGIS Composer to display a nice continuous band for a raster layer? What Happened to The Latex Symbols In the Libreoffice-Texmaths Equation Editor?

Copy Physics To Multiple Objects Using the cell fracture addon, I created many objects from my mesh. I want to have a rigid body physics on all of them. How would I copy one of the fractured pieces physics to all the pieces? I tired ctrl L and the copy attributes addon, but none of them have the option. Any help is great. I had always kind of wondered why we didn't see interference in things like windows -- we were taught that the condition is that the thickness of the film/slab/medium just has to be an integral number of wavelengths, $d=m\lambda$. My logic was, if visible light has wavelengths ~400-780nm, any window pane has got to be an integral number of wavelengths (or close to integral) for some of the wavelengths in the visible.  For example, if a window is, $6mm = 6\times10^6nm$ thick, then you should see interference for wavelengths (and some range around them) 200nm, 250nm, 300nm, 400nm, 500nm, 600nm... Because 6mm is an integral number of each of those.  Obviously that would be really annoying and isn't the case. I found  (warning: PDF) source that seems to explain it and I was wondering if what they're saying is sound. On the 10th page (p171 for them), it says that the reason we don't see this interference is that no window is that smooth, it has a variance in the thickness of at least several wavelengths, so the interference effect is effectively average out among all those thicknesses, which usually gets rid of it. They do the math and show that.  Is that the reason?  If so, that leads me to two questions: Could we, if we were really careful and used something like MBE, make a glass window with that sort of accuracy, and then see interference effects in the optical range? I know that quartz crystal monitors can easily give you nanometer accuracy for evaporators and sputterers, but they also have pretty limited growth rates.  My second question is, then, do we see interference effects in glass windows with electromagnetic radiation of a comparable wavelength, like microwaves?  Thanks! Take the square $[0,1]^2$ we take $n$ random lines through the square. You can choose random lines by choosing a point on one of the sides of the squares and randomly choosing a different point on any of the other three sides and then drawing a line connecting them.   What is the probability that after $n$ of these random lines the largest region is greater than or equal to $0.5$?  Any tips or cases help, thanks. Automatically updating column in feature class when another column is changed? I have a feature class in a file geodatabase and it contains a field called [curing] in short integer type and another field called [IsPopulated] in short integer as well.  What I want to achieve is to make [IsPopulated] automatically populated with "0" or "1" depending on whether the [curing] column is filled with a numeric value.  "Field Calculator" does not help as it's just a one-off operation and NOT automatic. Just for curiosity, sometimes while installing software throught apt-get install software_name the terminal prompt me for a confirmation "type Yes or No", but not allways.  I dont mean the sudo password prompt, but the message "Will be downloaded and configrated XXX Kb, continue?" (or something similar)  Why? Show a,b,c congruences when $a^2+b^2=c^2$ i would like to know how to prove that if $a^2+b^2=c^2$ then   a) $3|a$ or $3|b$  b) $5|a$ or $5|b$ or $5|c$  c) $4|a$ or $4|b$   Also that $a^2+b^2+c^2+1$ can't be divisible by 8  Thank you very much!
