I am struggling with this equation:
\begin{equation}\label{planewave}
\begin{aligned}
\textbf{E} \quad & = \quad \textbf{u}_{1} E_{0} e^{i(wt-\textbf{k\cdot r})} \\[5pt]
\end{aligned}
\end{equation}
Somehow it's not compiling even though I don't se any obvious error in the bracketing!
Thanks for the help!
Fixed! Posting here in case it can be useful to anyone in the future! :)

Comparing two xml files in soapui using groovy with XMLUnit2, Have some weird cases which are different in both files, but are acceptable. So have to ignore/skip those.
ResXML1:
<alpha:Errors>
<alpha:Error ShortText="SHiff" Type="11">Generic error occured.</alpha:Error>
<alpha:Error ShortText="SHiff" Type="12">Generic error occured.</alpha:Error>
</alpha:Errors>
<ShiftAttributes>
<ShiftAttribute ShiftAttributeCode="41"/>
<ShiftAttribute ShiftAttributeCode="17"/>
</ShiftAttributes>
<alpha:PriceInfo AgeQualifyingCode="10" Amount="19999.00" DiscountTypes="3" AMZAmount="225.00" NetAmount="19999.00" MCH="1" ValueAddAmount="150.00"/>
ResXML2:
<alpha:Warnings>
<alpha:Warning ShortText="SHiff" Type="11">Generic error occurred.</alpha:Warning>
</alpha:Warnings>
<ShiftAttributes>
<ShiftAttribute ShiftAttributeCode="17"/>
<ShiftAttribute ShiftAttributeCode="41"/>
</ShiftAttributes>
<alpha:PriceInfo AgeQualifyingCode="10" Amount="19999.0" DiscountTypes="3" AMZAmount="225.0" NetAmount="19999.0" MCH="1" ValueAddAmount="150.0"/>
If anyone have any idea, please help me in below conditions.
1) How to ignore child attribute order? tried different nodematchers(byXpath, byNameandText etc..), but no luck.
<ShiftAttribute ShiftAttributeCode="41"/>
<ShiftAttribute ShiftAttributeCode="17"/>
2) How to ignore decimal value, 100.0 & 100.00. Tried to use BigDecimalElementDifferenceEvaluator, but cannot able to complete in soapui. If we have any easy method please help me?
Found solution for first part of the above question
diff = DiffBuilder.compare(ResXML1).withTest(ResXML2)
.withNodeMatcher(
new DefaultNodeMatcher(
ElementSelectors.conditionalBuilder()
.whenElementIsNamed("ShiftAttribute")
.thenUse( ElementSelectors.byNameAndAttributes("ShiftAttributeCode"))
.elseUse(ElementSelectors.byName)
.build()
)
).build();
I was wondering today about how finding a specific value on a plot and drawing the right line that goes with. I used to do that on an old chart library, and I was wondering that perhaps this functionnality exist but I don't know how to find it.
The result should look like this: https://miro.medium.com/max/1070/1*Ckhi9soE9Lx2lIf9tPVLMQ.png
To provide some context, I'm doing a PCA over my data, and I would like to point out some thresholds at 97.5, 99 and 99.5% of explained cumuled variance.
Have a great day!
EDIT:
See Answer
As solved by ImportanceOfBeingErnest, here is the code:
whole_pca = PCA().fit(np.array(inputs['Scale'].tolist()))
cumul = np.cumsum(np.round(whole_pca.explained_variance_ratio_, decimals=3)*100)
over_95 = np.argmax(cumul>95)
over_99 = np.argmax(cumul>99)
over_995 = np.argmax(cumul>99.5)
plt.plot(cumul)
plt.plot([0,over_95,over_95], [95,95,0])
plt.plot([0,over_99,over_99], [99,99,0])
plt.plot([0,over_995,over_995], [99.5,99.5,0])
plt.xlim(left=0)
plt.ylim(bottom=80)
plt.ylabel('% Variance Explained')
plt.xlabel('# of Features')
plt.title('PCA Analysis')
Result in:
Thank you!
Hi I cannot find this anywhere and it seems so easy.
I am trying to get All the Features under specific Epic with Alteryx.
I am using this to get them all, but I want to make more precise.
https://rally1.rallydev.com/slm/webservice/v2.0/portfolioitem/feature?pagesize=2000
https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=https://rally1.rallydev.com/slm/webservice/v2.0/workspace/....
Can anyone help please?
Got another solution but it is still not perfect:
First I am getting SubEpics
https://rally1.rallydev.com/slm/webservice/v2.0/portfolioitem/subepic?pagesize=2000&&start=1&query=(Parent.FormattedID = E101)
And then Features:
https://rally1.rallydev.com/slm/webservice/v2.0/portfolioitem/feature?pagesize=2000&query=(((Parent.FormattedID = SE104) OR (Parent.FormattedID = SE101)) OR ((Parent.FormattedID = 102) OR (Parent.FormattedID = 103)))
OK! Correct answer for Feature is :) Got it with help from SAGI GABAY from CA:
https://rally1.rallydev.com/slm/webservice/v2.0/portfolioitem/feature?pagesize=2000&&start=1&query=(Parent.Parent.FormattedID
= E101)
I have also asked about the User Stories level and going this way (Parent.Parent.Parent.FormattedID) doesn't work anymore but you can do this:
https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?pagesize=2000&&start=1&query=(Feature.Parent.FormattedID = SE101)
I am working with the Rally/Excel plug-in and setting up queries/filters for our various delivery teams. One of the teams is named "Agency / L&C". The & is causing me all sorts of problems that I cannot seem to get past. The current filter is:
((Release.Name = "2013 November") AND (Project.Name = "Agency / L&C"))
When I execute the query I get this error:
Query failed due to errors:
Could not parse: Cannot parse expression "((Release.Name = "2013 November") AND (Project.Name = "Agency / L" as a query
I have tried several things, ' before and after, '' before and after, %, " and \ and nothing seems to be making it register the & as text.
Thanks for the help
This is an educated guess but I would think the problem arises from the ampersand not being escaped before the request is made to the to the API. You might try changing it to "%26" (the HTML code for "&") and see what you get.
I have some complex queries in my plugin which require me to use the ->query() and not the ->find() methods.
I couldn't understand how to sanitize the raw sql so I guessed someone here can guide me.
So the first step is to include the App:import("sanitize"); before the declaration of the class.
Now let's say I have this :
$query = $this->Mytable->query("SELECT * FROM mytable WHERE " . $WHERECLAUSE . ";");
Can some one help me out in sanitizing my query as i got completely lost in the cookbook.
Thanks for your help, it is very much appreciated.
Use this: Sanitize::clean($query, $options)
Sanitize::clean is used for values / whole arrays such as $this->data.
$WHERECLAUSE = Sanitize::clean($whereclause, array('escape'));
$query = $this->Mytable->query("SELECT * FROM mytable WHERE " . $WHERECLAUSE . ";");
That'll do the trick. array('escape') is used for SQL statements.
