how to uninstall/remove abaqus from Ubuntu What should I do to uninstall/remove Abaqus from Ubuntu 14.04 LTS?  I did not install abaqus by commmand "sudo apt-get ....", now I don't know how to remove it from ubuntu. I followed instruction as shown in the following . Could anyone help me to solve?
How do I install applications in Ubuntu? How can I install applications like Google Chrome on Ubuntu?  Are there any commands to install an application?    Index of answers:
I am a bit lost how one has deduced the formula for electric field with electric dipole because of some inconsistency between different sources. The  contains a delta function in the formula, but  gives only the formula without the delta function,  $$\bar{E} = -\nabla \phi = \frac{-p}{4\pi \epsilon_{0} r^{3}} ( \hat{e}_{z}-3\hat{u}_{r}(\hat{u}_{r} \cdot \hat{u}_{z}) ) $$  Is it intentionally left out?  My notes mention that the dipole is with a circular thing $P=Q d$ where $d$ is distance and $Q$ is charge.

Bounded operator that does not attain its norm What is a bounded operator on a Hilbert space that does not attain its norm? An example in $L^2$ or $l^2$ would be preferred.  All of the simple examples I have looked at (the identity operator, the shift operator) attain their respective norms. I have a cable as in the drawing. The black parts are insulators and the brown parts are copper, so there is a big copper cable and inside are two smaller copper cables. When the big copper cable is tied to ground I can use a time domain reflectometer (TDR) on the smaller cables to determine the length of the cable. What happens if the big copper cable is in use with a current running through it that is 1000 times bigger than the current running through the two smaller copper cables? Will I still be able to determine the length with a TDR? I think there shouldn't be a capacitance between the two smaller copper cables - but how am I then able to measure with it a TDR?

What would be the best way to calculate someone's age in years, months, and days in T-SQL (SQL Server 2000)?  The datediff function doesn't handle year boundaries well, plus getting the months and days separate will be a bear.  I know I can do it on the client side relatively easily, but I'd like to have it done in my . Laptop randomly waking up = Hibernate / Low Battery? In how many ways $5$ different rings can be worn on $4$ fingers ?   Although these is similar question here   But I want to answer it in different way which is like take $4$ fingers like $a,b,c,d$. Now $a$ can be filled in $5$ ways and so are others. So total ways are $5^4$ but answer is $4^5$. What is wrong in my reasoning? Which cases have I left out? Suppose that $n \ge 2$. How to prove that the set $\mathcal D \subset M_n(\mathbb R)$ of the diagonalizable real matrices is not dense in $M_n(\mathbb R)$? Ok guys, continuing my passage through edwards... here is the question... thanks for hints/solutions in advance:  Suppose $f(x,y,z)=0$ can be solved for each of the three variables $x,y,z$ as a differentiable function of the other two. Then prove that  $\displaystyle \frac{\partial x}{\partial y} \frac{\partial y}{\partial z} \frac{\partial z}{\partial x} = -1$  Verify this is the case for the ideal gas equation $pv =RT$ where (where $p,v,T$ are the three variables and $R$ is the constant). I am trying to grab the capital letters of a couple of words and wrap them in span tags. I am using  for extract and wrapping purposes, but it's not outputting anything.  preg_replace("/[A-Z]/", "&lt;span class=\"initial\"&gt;$1&lt;/span&gt;", $str) how to fix ioctl permissions denied error? I searched in lots of websites/forums but did not find a solution for this problem, and this site is last chance, this is problem: This problem have several other users too. my phone is Galaxy S7 Edge , exynos, Oreo 8.0 (Stock ROM), rooted with magisk latest version. root works well in other applications. In pentesting applications like csploit, Network Spoofer, WifiKill and others  root works well(grants permission)  but when start using options of app(for example, arp spoofing, network sniffer, MITM, etc) drops same error: [ERROR] Unable to retrieve local hardware address libnet ( ioctl: Permission denied ) what to do? Can this issue fixed? or exactly which permission is it?  Also one interesting thing, when I installed old version of WifiKill app it worked - killed wifi connection. If I replace my main panel, will I need to fit AFCIs? This question is about whether "circuits" can be grandfathered if the breaker or panel is changed but the circuit is otherwise not disturbed.   Code is NEC 2017.  My existing main panel has plenty of ampacity but few spaces, and thus, is totally full.  I have several potential paths for an upgrade.    One involves fitting a subpanel and moving 4 circuits (2 double-stuff breakers) there, and adding circuits there.    The other involves outright replacing the main with a very fine 60 space main panel.  No more space problems!  But what happens with AFCI and GFCI requirements? If this were a new house,  nearly all my circuits would require it, but I am grandfathered.  Will the  "new main" scenario void the grandfathering and require that nearly all circuits be upgraded to that protection?   Or can I just move over my old breakers and call it good? Normalising Constant for exponentiated function What would the normalising  constant be of the following, or atleast an approximation? I would like to avoid sampling.  $$f(\theta)=\exp(-k_1e^{-k_2\theta^2}-\theta^2)\qquad\theta\in(-\infty,\infty), \quad k_1,k_2&gt;0$$  In the event that its not possible, what would be a valid polynomial lower bound on $\log(f(\theta))$, that would take into account $k_1$  For anyone, who is interested, I end up with this expresssion because I place a Gaussian prior over (a squared exponential) kernel parameters, and trying to use variational bayes (hence, a lower bound). How to avoid the 'not properly formatted as code' alert I have an image with a woman, and I need to make an ad (size 260mmx125mm). I want to put the woman to the left side, but then right side becomes empty. So, how I should solve the problem? I have picked the color from image, but it is definitely different than in the actual picture.  Should I use the Clone Stamp Tool in Photoshop, or there is a better way to do this?  By the way, it will be used in print, so I need a good quality. Show that the operator norm is submultiplicative We had in our lecture on numerical analysis the following: Let $\mathrm{Lin}(X,Y)$ be the set of all linear maps $X\rightarrow Y$. Let $A\in\mathrm{Lin}(\mathbb R^l,\mathbb R^n)$ and $B\in\mathrm{Lin}(\mathbb R^n,\mathbb R^m)$ and $\|C\|_{op}:=\max_{\|x\|\leq1}\|C(x)\|$. Then our lecturer followed $\|A\circ B\|_{op}\leq\|A\|_{op}\cdot\|B\|_{op}$. So he didn't prove it and so I've tried it by my own. My attempt: $$\begin{aligned} \|A\circ B\|_{\mathrm{op}} &amp;= \max_{\|x\| &lt; 1}\|(A \circ B)(x)\| \\ &amp; \leq \max_{\|x\| &lt; 1} \|A\|_{\mathrm{op}} \|B(x)\| \\ &amp;= \|A\|_{\mathrm{op}} \max_{\|x\|\leq1}\|B(x)\|\\ &amp;= \|A\|_{\mathrm{op}}\|B\|_{\mathrm{op}} \end{aligned}$$ But this seems too easy. I am really interested in a nice proof so anybody could help? Thanks a lot! I've got this situation:  ./ ./myscript.sh ./arguments.txt ./test.sh   Inside myscript.sh, I have to run the file test.sh, passing to it the arguments contained inside arguments.txt.  myscript.sh is:  arguments=$(cat arguments.txt) source test.sh $arguments   This works well if if arguments.txt contains at most one argument:  firstargument    The substitution is:  ++ source test.sh 'firstargument'   But the problem is with two or more arguments. It does this:  ++ source test.sh 'firstargument secondargument'   Also, I don't know in advance the number of arguments inside arguments.txt. There can be zero or more.
