i'm working on my Final university Project , and my time is too short
the project is about Wireless sensor network and i have to simulate one of the recent papers about it.
most of the coding is done but i have a simple problem about linked list(i use matlab and import java libraries into it for using linked list)
okay
here is some explanation
i have a queue/list that every time head of the list is checked that is it the goal or not
if its not a goal it deletes the first item and gets the second one which is actualy the first one in the list
problem occurs when my list has only 1 item and its not goal so code delete the first item , AFTER that
code tries to get the first item which is null and empty thats when Error happens ,
my goal is after checking/searching all the list if it was successful turn flagg=1 if not flagg=0
while temp ~= goal;
for K=1:size(G,1)
if temp == G(K,1)
q.add(G(K,2))
end
end
if (~q.isEmpty())
q.removeFirst();
temp=q.getFirst();
else
flagg=1
end
end
Thanks.

I´m trying to set a connection with a conditional on the temperature, to represent a temperature-sensible charging pipe that works inside a stratified heat storage tank, with the following for loop reading the several volumes of the tank,
`for i in 2:nSeg loop
if (sensor_T_inflow.T > vol[i].T) and (sensor_T_inflow.T < vol[i-1].T) then
connect(feedPort, vol[i].ports[3])
annotation (Line(points={{-50,-60},{6,-60},{6,
-16},{16,-16}}, color={0,127,255}));
end if;
end for;`
However I get the errors such as this one for the volume 2:
Failed to expand block containing connect:
if (sensor_T_inflow.T > vol[2].T and sensor_T_inflow.T < vol[1].T) then connect(feedPort, vol[2].ports[3]); end if;
The model contained invalid connect statements.
Check aborted.
This might have a silly solution but I checked the names of all my elements and their temperature properties and they match with this code snippet, and I confirmed the error comes specially from the if conditional. Here is my model If you could take a look at it.
I tried commenting out the conditional and the check was succesful, only that I have a misbalance of about 40 variables to equations. If you got any advice on how to solve those misbalances I´d be much grateful as well.
Thanks a lot in advance.
The connect-statements may not depend on time-varying variables.
(The technical statement is first in the list in https://specification.modelica.org/master/connectors-and-connections.html#restrictions-of-connections-and-connectors )
A solution would be to turn that into an array of valve-components, and have them controlled in a similar way.

Hi fellow nerds.
I'm trying to make the current column (most recent interaction date with client) display the max values (most recent dates) from ContactLog!b:b (dates of all recorded interactions), when the client name in ContactLog!A:A matches to the client name in current row column A.
After many days of trying, I've found several formulas to successfully achieve this result for the current cell only.
=MAXIFS(ContactLog!B:B, ContactLog!A:A, A:A)
=MAX(FILTER(ContactLog!B4:B, ContactLog!A4:A=VLOOKUP(A2, ContactLog!A4:B, 1, FALSE)))
=MAX(QUERY(ContactLog!A4:B, ""SELECT B WHERE A = '""&VLOOKUP(A2, ContactLog!A4:B, 1, FALSE)&""'"", 0))
=IF(COUNTIF(ContactLog!A:A, A2),MAX(FILTER(ContactLog!B:B, ContactLog!A:A = A2)),"")
But none of these seem to work with arrayformula, to spread to the entire column. I'd like this result to apply automatically to the entire column (wherever column A is not blank).
It's displaying the correct max value for the first cell (in which the formula is written), and I could drag the formula down, but not spreading automatically as an array.
I've tried using =match with =filter, but that keeps running into mismatched range row sizes. (I've previously solved that by using filter within a filter, but can't figure that out here).
[I have a similar issue for the nearby columns also, "most recent interaction method", and "reminders & goals". The formula there is:
=INDEX(ContactLog!C:C, MATCH(MAX(IF(ContactLog!A:A=A2, IF(ContactLog!B:B=MAX(IF(ContactLog!A:A=A2, ContactLog!B:B)), ROW(ContactLog!B:B)))), ROW(ContactLog!B:B), 0))
And
=IFERROR(CONCATENATE(JOIN(" • ",FILTER(ContactLog!D:D,ContactLog!A:A=A2, ContactLog!D:D<>"")),IF(INDEX(ContactLog!D:D,MAX(IF(ContactLog!A:A=A2,ROW(ContactLog!D:D))))="","","")),"")
They both work great, but I can't get them to work with arrayformula...]
What am I missing?
You can do something like this with BYROW, that allows you to expand your formula through the column and be calculated "row by row". Using your first option:
=BYROW(A:A, LAMBDA (each,IF(each="","",MAXIFS(ContactLog!B:B, ContactLog!A:A, each))))
I'm trying to test the model (model.bin) i've made with fastText on a test file (test.txt). In this test file, i have 135 labelised data. I'm expecting from fastText to test my model on this number of example, but instead, it only test it over 1 example. Where does come from this problem ?
I've already tried to do such a thing with another model and another testing file and all worked nicely.
this is how I test my model. model_baby.bin is the model, and test.data.txt is my testing file.
./fasttext test model_baby.bin test.data.txt
N 1
P#1 1
R#1 0.0164
Number of examples: 1
And here is an extract from my testing file
__label__4.0 I love the fact you can hide your stuff. Only down is that the straps to hold it at midpoint and bottom could be better designed for your car. It's got plenty of room which is great. __label__5.0 This hid our ipad wonderfully. Especially for those quick stops where we all had jump out and use the restroom. It zipped, folded and held all our stuff for the kids in the back seat. __label__3.0
As i have more than 1 labelised example in my testing file, I expect the output "Number of examples: " to be at least more than 1 but the actual one is "1"
From the official documentation (https://fasttext.cc/docs/en/supervised-tutorial.html): Each line of the text file contains a list of labels, followed by the corresponding document. All the labels start by the __label__ prefix, which is how fastText recognize what is a label or what is a word.
I don't understand very much your extract. I think it should be like this:
__label__4.0 I love the fact you can hide your stuff. Only down is that the straps to hold it at midpoint and bottom could be better designed for your car. It's got plenty of room which is great.
__label__5.0 This hid our ipad wonderfully. Especially for those quick stops where we all had jump out and use the restroom. It zipped, folded and held all our stuff for the kids in the back seat.
__label__3.0 ...
I have created this workflow by copying a workflow(macro) I recorded from our company system in the hope to relieve me from heavy data entry work. However, when I play the workflow, it failed to select the right row on a list(grid). Instead, it always selects the first row no matter what row I designate. I don't know which programming language the system uses. It was saved using the .P extension. Here is a part that caused the problem. The third last sentence (SELECT_ROW("2")) was not properly executed.
SELECT_TAB("po-proc-tabpage-1").
SET_FIELD("scr-po-num","02.6430").
SELECT_TAB("NONE").
CHOOSE_BUTTON("button-edit").
CHOOSE_BUTTON("button-items").
GET_DIALOG("poitment.p","poitment-004").
SELECT_GRID("br-item").
RESET_GRID_SORT().
SELECT_ROW("2").
CHOOSE_BUTTON("badd-charges").
GET_DIALOG("poitmchg.p","poitmchg-004").
Thanks in advance for any comments.
I am trying to create some joblets in Talend that will speed up some processes.
I have an input from a MSSQLInput, the results are then sorted and filtered a little. Then I have a tMemorizeRows and a tJavaFlex, the purpose of this is to memorize the rows in a column to preform a count. The count is based on a customer ID, once the the id changes the count starts back to 1 and the proccess begine again and continues to the end. I have refactored this as a joblet but it does not work, the error is:
ID_tMemorizeRows_1 cannot be resolved to a variable
I have a tJavaFlex which starts with
int counte = 1;
The Main code is
if(ID_tMemorizeRows_1[0].equals(ID_tMemorizeRows_1[1]))
{
counte = counte + 1;
}
else
{
counte = 1;
}
context.Enqnum = counte;
The Enqnum variable and is created correctly and added into a tMaps component.
Does anyone know why this is happening, one person told me it is because when you move something to a joblet it gets a new/different name so it has to be specifically called in the Java, if this is the case how do I find the name out?
Thank you
Rich
I do have a resolution. I have tried to add images however my reputation is not high enough.
When using joblets we know that Talend essentially recycles the code used in the joblet by inserting it into the code for the main job.
This is the joblet I have created, i know it works because I have refactored it to a joblet instead of building it from sctatch. What its doing is simply memorises row 0 and row 1 in an ordered data set, the java performs a count and the tMap appends the result to the job (as Mentioned above).
(I will try it inser image in my question, I do not have enough reputation point to insert it into a question).
When the job is run it runs fine. But problems occur when I want to reuse the same joblet in another part of the job. What Talend does is it assigns names within the source code to each component depending on the name of the joblet.
For example, if the Joblet was called ThisJob, then tMemorizeRows_1 would be called ThisJob_1_tMemorizeRows_1.
The row within the component (in this example ReferenceID) would renamed as:
ReferenceID_ThisJob_1_tMemorizeRows_1.
But when you add a second joblet to your job it gives it a new name, eg ThisJob_2. This name will be different depending on how much you have been altering your job before you add the second joblet. Therefore the number within the name will depend on this activity.
If you add the joblet into your job immediately then the joblet would be called ThisJob_2, if you have added 5 other components before you add it in then the joblet is likely to be called ThisJob_6 etc. (I'm not 100% sure how talend renames components)
When you add a joblet, You can see the name of the joblet on the joblet component, this then reverts back the the original joblet name when you create any links/joins to other components.
Its also important that each component within the code is assigned to a variable called currentComponent.
Resolution
What I did was used the Java code to split the name using the code below. This way I can get the current name of the of the joblet and use this name in my Java.
String string = currentComponent;
String[] parts = string.split("_");
String part1 = parts[0];
String part2 = parts[1];
String joblet = part1+'_'+part2;
String newrow = "ReferenceID_"+joblet+"_tMemorizeRows_1";
I hope this makes sense.
Thanks
