I am trying to make a table that is similar to this:  ...and failing. Here is my code:  \documentclass[a4paper]{article}  \usepackage[english]{babel} \usepackage[utf8x]{inputenc} \usepackage{graphicx} \usepackage{wrapfig} \usepackage{lipsum} \usepackage{multirow}  \begin{document} \begin{table}[h] \caption{This is a caption} \centering % centering table \begin{tabular}{|l| p{5cm} | p{5cm} | c|}  \hline  Domain &amp; Sub-domain &amp; Use case &amp;Suitable \\ \hline % inserts single-line Metering &amp; Water, Electricity or Gas distribution &amp; Collect daily or bi-             hourly water, electricity and gas usage data. &amp; Yes \\ \hline \multirow{9}{2cm}{Infrastructure networks} &amp; Water \&amp; Gas transportation &amp;      Water and Gas infrastructure network surveillance (alarm, metering parameters) &amp; Yes\\   &amp; Power Grid &amp; Electricity transport status monitoring and command/control &amp; Yes \\  &amp; Power Grid &amp; Command and control &amp; Yes \\  &amp; Traffic monitoring &amp; Traffic light functionality monitoring, traffic level      monitoring, &amp; Yes \\ &amp; Traffic shaping &amp; emergency gate status control, traffic lights control &amp;     Potentially \\ \hline  \multirow{7}{3cm}{Environmental \&amp; Smart City} &amp; Pipelines &amp; Collect data on     Metrics (temperature, pressure), alarms, leakage, vibration &amp; yes \\ &amp; Waste and Drains management               &amp; Collect data on levels                                            &amp; yes \\ &amp; Atmospheric Noise-Pollution monitoring    &amp; Collect data on humidity,     noise, temperature,$CO_2$,CO, etc. &amp; yes \\ &amp; Public Lighting Monitoring &amp; Bulb monitoring &amp; yes \\ &amp; Parking management &amp; Availability monitoring &amp; yes \\ \hline  \end{tabular} \end{table} \end{document}   Which creates this:  It's fairly close to what I want, but I can't find a way to make the horizontall lines appear wher they should. \hline creates lines that span the first row too.  Any help would be much appreciated.
In a table, how can I draw a horizontal line that goes only through some of the cells? I mean a line like the one in the Foo and in the Bar area of this table:  +----+-----+ |Foo |1 |2 | |    |1 |2 | |    +--+--+ |    |1 |2 | |    |1 |2 | +----+-----+ |Bar |1 |2 | |    |1 |2 | |    +--+--+ |    |1 |2 | |    |1 |2 | +----+--+--+
Why Listen to Music, why not Listening Music A solid sphere has charge $q$ and radius $R$. Find the potential at a point a distance $r$ from the center of the sphere where $r&gt;R$, using infinity as the reference point.  My attempt:  From Gauss' theorem we may deduce that $\displaystyle\mathbf{E}=\frac{1}{4\pi\epsilon_0}\frac{q}{r'^2}\hat{\mathbf{r}}$ where $r'$ is the distance of an arbitrary point from the center of the sphere provided $r'&gt;R$.  $V=-\int_\infty^\mathbf{r}\mathbf{E}\cdot d\mathbf{l}$  My question: What is $d\mathbf{l}$? Since we are traversing in the direction opposite to $\hat{\mathbf{r}}$, I think it should be $-dr'\hat{\mathbf{r}}$. But when I use it to find $V$, I get a sign error. Please help!

Ubuntu 12.04 boots to TTY1 Alrighty, I have perused the threads already in existence and am finding none of them seem to have the exact combination of variables I've got going.

How can I enable multiple users login at a time in remote system? Recently we bought dedicated server with Windows Server 2012 Standard.It's allowing 2 people at a time.So I want to allow more people at a time.  How can I do this? We were trying to come up with an easy way to generate a rational number in between two existing rational numbers with a fairly low numerator and denominator (the way we were doing this earlier was to find the average of the two rationals, but that results in a denominator of up to $c * d$. Does this inequality hold for all values of $a, b, c, d$? Amazon RDS I/O requests - 1 query = 1 billable I/O? I have an InnoDB database that I'd like to migrate onto Amazon RDS.

Let $X$ be adapted integrand, for which we know that $E[\int_0^T X_s^2 \, ds]&lt; \infty $. Let $0≤s&lt;t≤T$ and we have some $W∈F_s$ ($F_s$ is $\sigma$-algebra) and we know $E[\int_s^t W^2X_u^2 \, du]&lt;\infty$. I have to show  that $\int_s^t W X_u \, dB_u=W \int_s^t X_u dBu$.  I know that for simple integrands this follows from definition. We also know that for $X$ there exists sequence of elementary integrands $X^n$ such that $E[ \int_0^t (X^n_u-X_u)^2 \, du]$ converges to $0$, when $n \to \infty$. From this one can see that it also holds $E[ (\int_0^t (X^n_u-X_u) \, dB_u)^2]$. I wonder if I can show that it  holds $E[ |(\int_s^t W (X^n_u-X_u) \, dB_u)|] \to 0$ as $n \to \infty$ . (I think I should use Cauchy- Schwarz inequality: $E(XY)^2 \leq E(X^2)E(Y^2)$, but not sure where. If I could show this convergence in $L^1$, it would be enough for my proof. If I rewrite it as $E[E[|(\int_s^t W(X^n_u-X_u) \, dB_u)|  \mid F_s]]$ I don't know if I can put $W$ out of integral. Would it be correct? Any help would be really very appreciated. Thanks.

Why are more powerful tools using higher voltage? AFAIK each of the world leading cordless power tools manufacturers produces several "product lines" of cordless power tools with different voltages. For example, Bosch currently produces tools with Li-Ion batteries with 10,7V, 14,4V, 18V and 36V output and the higher the voltage the more powerful a tool is.  Now those tools are powered by batteries that are assembled from cells with lower voltage (something like 3,7 volts for Li-Ion cells I guess) and cells are connected in sequence until the target voltage is reached.  They could instead connect cells in parallel. They would have the same voltage, but higher current and that would again yield higher power.  Why do they choose higher voltage over same voltage and higher current to get higher power in electric tools? How to test if these two samples are from the same distribution?
