  • 1-DimArray Counting same elements (0,1)

    - by Chris
    Hello, I have a 1-dim array that fills up a table of 40 random elements (all the values are either 0 or 1). So i wanne "count" the largest row of the values net to each otherto each other.. Meaning for example : 111100101 = the longest row would be 1111 (= 4 elements of the same kind closest to each other). So 011100 would result in the longest row being 3 elements (3 x 1). My problem i have no idea how to check upon the "next element" and check if its a 0 or 1. Like the first would be 1111 (count 4) but the next would be a 0 value = meaning i have to stop counting. My idea was placing this value (4) in a other array (example: 111100101) , and place the value of the 1's back on zero. And start the process all over again. To find the largest value i have made a other method that checks up the biggest value in the array that keeps track of the count of 0's 1's, this is not the problem. But i cannot find a way to fill the array tabelLdr up. (having all the values of the group of elements of the same kind (being 0 or 1). In the code below i have 2 if's and offcourse it will never go into the second if (to check if the next value in the array is != then its current state (being 0 or 1) Best Regards. public void BerekenDeelrij(byte[] tabel, byte[] tabelLdr) { byte LdrNul = 0, Ldréén = 0; //byte teller = 0; for (byte i = 0; i < tabel.Length; i++) { if (tabel[i] == 0) { LdrNul++; //this 2nd if cleary does not work, but i have no idea how to implend this sort of idea in my program. if (tabel[i] == 1) //if value != 0 then the total value gets put in the second array tabelLdr, { tabelLdr[i] = LdrNul; LdrNul = 0; } } if (tabel[i] == 1) { Ldréén++; if (tabel[i] == 0) { tabelLdr[i] = Ldréén; Ldréén = 0; } } }/*for*/ }

  • Best neural network for certain type of pattern analysis?

    - by fred basset
    Hi All, I'm working on a system that will send telemetry data on machine operation back to a central server for analysis. One of the machine parameters we're measuring is motor current drawn vs time. After an operation is finished we plan to send back an array of currents vs time to the server. A successful operation would have a pattern like a trapezoid, problematic operations would have a pattern completely different, more like a large spike in values. Can anyone recommend a type of neural network that would be good at classifying these 1D vectors of current values into a pass/fail type output? Thanks, Fred

  • simple query Delete records in a table based on count logic

    - by user1905941
    a table with a pk and status column which is having values as 'Y','N','NULL' Query: get the count of records with status column as 'Y', if this count exceeds 1% of total count of records then dont delete , else delete the records in the table. i tried like this Declare v_count Number; v_count1 Number; BEGIN v_count := select count(*) from temp; v_count1 := select count(*) from temp where status = 'Y' ; v_count := v_count + ((0.1) * (v_count)) if (v_count1 > v_count) { insert into temp1 values(pk,status) } else { Delete from temp ; } END;

  • Make a simulation using python

    - by user3727759
    I am new to programming and using python. What I am trying to do is create a simulation of a thermostat system by using python. Is there a way to create a program that I can input data, for example temperature and humidity values and then have python constantly plotting the data as I enter the values. This is to simulate a device gathering data and sending it to this program and having it being plotted. I have found ways to plot data by using matplotlib but I have not been able to find a way that I can input the data and have the plot upgrade constantly. Thanks any advise is appreciated.

  • files get uploaded just before they get cancelled

    - by user1763986
    Got a little situation here where I am trying to cancel a file's upload. What I have done is stated that if the user clicks on the "Cancel" button, then it will simply remove the iframe so that it does not go to the page where it uploads the files into the server and inserts data into the database. Now this works fine if the user clicks on the "Cancel" button in quickish time the problem I have realised though is that if the user clicks on the "Cancel" button very late, it sometimes doesn't remove the iframe in time meaning that the file has just been uploaded just before the user has clicked on the "Cancel" button. So my question is that is there a way that if the file does somehow get uploaded before the user clicks on the "Cancel" button, that it deletes the data in the database and removes the file from the server? Below is the image upload form: <form action="imageupload.php" method="post" enctype="multipart/form-data" target="upload_target_image" onsubmit="return imageClickHandler(this);" class="imageuploadform" > <p class="imagef1_upload_process" align="center"> Loading...<br/> <img src="Images/loader.gif" /> </p> <p class="imagef1_upload_form" align="center"> <br/> <span class="imagemsg"></span> <label>Image File: <input name="fileImage" type="file" class="fileImage" /></label><br/> <br/> <label class="imagelbl"><input type="submit" name="submitImageBtn" class="sbtnimage" value="Upload" /></label> </p> <p class="imagef1_cancel" align="center"> <input type="reset" name="imageCancel" class="imageCancel" value="Cancel" /> </p> <iframe class="upload_target_image" name="upload_target_image" src="#" style="width:0px;height:0px;border:0px;solid;#fff;"></iframe> </form> Below is the jquery function which controls the "Cancel" button: $(imageuploadform).find(".imageCancel").on("click", function(event) { $('.upload_target_image').get(0).contentwindow $("iframe[name='upload_target_image']").attr("src", "javascript:'<html></html>'"); return stopImageUpload(2); }); Below is the php code where it uploads the files and inserts the data into the database. The form above posts to this php page "imageupload.php": <body> <?php include('connect.php'); session_start(); $result = 0; //uploads file move_uploaded_file($_FILES["fileImage"]["tmp_name"], "ImageFiles/" . $_FILES["fileImage"]["name"]); $result = 1; //set up the INSERT SQL query command to insert the name of the image file into the "Image" Table $imagesql = "INSERT INTO Image (ImageFile) VALUES (?)"; //prepare the above SQL statement if (!$insert = $mysqli->prepare($imagesql)) { // Handle errors with prepare operation here } //bind the parameters (these are the values that will be inserted) $insert->bind_param("s",$img); //Assign the variable of the name of the file uploaded $img = 'ImageFiles/'.$_FILES['fileImage']['name']; //execute INSERT query $insert->execute(); if ($insert->errno) { // Handle query error here } //close INSERT query $insert->close(); //Retrieve the ImageId of the last uploded file $lastID = $mysqli->insert_id; //Insert into Image_Question Table (be using last retrieved Image id in order to do this) $imagequestionsql = "INSERT INTO Image_Question (ImageId, SessionId, QuestionId) VALUES (?, ?, ?)"; //prepare the above SQL statement if (!$insertimagequestion = $mysqli->prepare($imagequestionsql)) { // Handle errors with prepare operation here echo "Prepare statement err imagequestion"; } //Retrieve the question number $qnum = (int)$_POST['numimage']; //bind the parameters (these are the values that will be inserted) $insertimagequestion->bind_param("isi",$lastID, 'Exam', $qnum); //execute INSERT query $insertimagequestion->execute(); if ($insertimagequestion->errno) { // Handle query error here } //close INSERT query $insertimagequestion->close(); ?> <!--Javascript which will output the message depending on the status of the upload (successful, failed or cancelled)--> <script> window.top.stopImageUpload(<?php echo $result; ?>, '<?php echo $_FILES['fileImage']['name'] ?>'); </script> </body> UPDATE: Below is the php code "cancelimage.php" where I want to delete the cancelled file from the server and delete the record from the database. It is set up but not finished, can somebody finish it off so I can retrieve the name of the file and it's id using $_SESSION? <?php // connect to the database include('connect.php'); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); die(); } //remove file from server unlink("ImageFiles/...."); //need to retrieve file name here where the ... line is //DELETE query statement where it will delete cancelled file from both Image and Image Question Table $imagedeletesql = " DELETE img, img_q FROM Image AS img LEFT JOIN Image_Question AS img_q ON img_q.ImageId = img.ImageId WHERE img.ImageFile = ?"; //prepare delete query if (!$delete = $mysqli->prepare($imagedeletesql)) { // Handle errors with prepare operation here } //Dont pass data directly to bind_param store it in a variable $delete->bind_param("s",$img); //execute DELETE query $delete->execute(); if ($delete->errno) { // Handle query error here } //close query $delete->close(); ?> Can you please provide an sample code in your answer to make it easier for me. Thank you

  • Possible to add hook as android fetches XML-strings?

    - by user247245
    I'm on my first week with android and would appreciate any insight if it's possible to hook or override the default behaviour when an android application reads their values from the resource-files to the shown layouts. What I want is to over time be able to add new/updated strings OTA and store locally and then on launch of application load new values instead of the ones in the default /res. Ideally i guess, would be an override of setContentView. Files holding updates will be in same xml-format as those in /res. (Please, no advices in other ways to do this. Just need to know if it's at all possible, without hacking the SDK) regards, /t

  • mysql result for pagination

    - by Reteras Remus
    The query is: SELECT * FROM `news` ORDER BY `id` LIMIT ($curr_page * 5), ( ($curr_page * 5) + 5 ) Where $curr_page is a php variable which is getting a value from $_GET['page'] I want to make a pagination (5 news on each page), but I don't know why the mysql is returning me extra values. On the first page the result ok: $curr_page = 0 The query would be: SELECT * FROM `news` ORDER BY `id` LIMIT 0, 5 But on the second page, the result from the query is adding extra news, 10 instead of 5. The query on the second page: SELECT * FROM `news` ORDER BY `id` LIMIT 5, 10 Whats wrong? Why the result has 10 values instead of 5? Thank you!

  • Does Java have "properties" that work the same way properties work in C# (see the body of my text)?

    - by tyrone302
    In C#, you can use properties to make a data field publicly accessible (allowing the user to directly access it), and yet retain the ability to perform data validation on those directly-accessed fields. Doese Java have something similar? For Instance, suppose there exists a C# class with the following implementation(see below): public class newInt{ public newInt(){...} public int x{ get{ return this.x } set{ this.x = isValid(value) } } } private static int isValid(int value){...} This definition in the class allows the user to "naturally" use the data field 'x' when retrieving values from it and assigning values to it. Below is how it would be used in main. public class Test{ public static void main(String[] args){ newInt a = new newInt(); a.x = 50; int b = a.x; } } The question is... can java do this as well? if so, what is it called?

  • ASP.net PreInit() Vs Init()

    - by ASP.netBeginner
    From local forum i understood that PreInit can be used to handle the following PreInit() >Master pages can be called dynamically >Themes can be set dynamically >Programatically add controls to controls collection and i read Init() is for Init() In this event, we can read the controls properties (set at design time). We cannot read control values changed by the user because that changed value will get loaded after LoadPostData() event fires. Question I am not getting the point "We cannot read control values changed by the user".Where do users change the value of control?.Example would help me to understand the point.

  • SQL Server dynamic pivot table

    In SQL Server, I have two tables TableA and TableB, based on these I need to generate a report which is kind of very complex and after doing some research I come to a conclusion that I have to go with SQL Pivot table but I dont have any idea about the SQL Pivot feature so, can anyone please help me on this. Please see the details below: Create table TableA ( ProjectID INT NOT NULL, ControlID INT NOT NULL, ControlCode Varchar(2) NOT NULL, ControlPoint Decimal NULL, ControlScore Decimal NULL, ControlValue Varchar(50) ) Sample Data ------------- ProjectID | ControlID | ControlCode | ControlPoint | ControlScore | ControlValue P001 1 A 30.44 65 Invalid P001 2 C 45.30 85 Valid Create table TableB ( ControlID INT NOT NULL, ControlChildID INT NOT NULL, ControlChildValue Varchar(200) NULL ) Sample Data ------------ ControlID | ControlChildID | ControlChildValue 1 100 Yes 1 101 No 1 102 NA 1 103 Others 2 104 Yes 2 105 SomeValue Output should be in a single row for a given ProjectID with all its Control values first & followed by child control values (based on the ControlCode (i.e.) ControlCode_Child (1, 2, 3...) and it should look like this

  • how-to initialize 'const std::vector<T>' like a c array

    - by vscharf
    Is there an elegant way to create and initialize a const std::vector<const T> like const T a[] = { ... } to a fixed (and small) number of values? I need to call a function frequently which expects a vector<T>, but these values will never change in my case. In principle I thought of something like namespace { const std::vector<const T> v(??); } since v won't be used outside of this compilation unit.

  • Outer select column value in joined subquery?

    - by Michael DePetrillo
    Is it possible to use a column value from an outer select within a joined subquery? SELECT table1.id, table2.cnt FROM table1 LEFT JOIN (SELECT COUNT(*) as `cnt` FROM table2 where table2.lt > table1.lt and table2.rt < table1.rt) as table2 ON 1; This results in "Unknown column 'table1.lt' in 'where clause'". Here is the db dump. CREATE TABLE IF NOT EXISTS `table1` ( `id` int(1) NOT NULL, `lt` int(1) NOT NULL, `rt` int(4) NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1; CREATE TABLE IF NOT EXISTS `table2` ( `id` int(1) NOT NULL, `lt` int(1) NOT NULL, `rt` int(4) NOT NULL) ENGINE=MyISAM DEFAULT CHARSET=latin1; INSERT INTO `table1` (`id`, `lt`, `rt`) VALUES (1, 1, 4); INSERT INTO `table2` (`id`, `lt`, `rt`) VALUES (2, 2, 3);

  • Good Design for Initialization of Static Array

    - by jplot
    I have a question regarding good design in C++. I have a class A, and all objects of this class use an integer array of constant values (they should share the same array, as their values are constant). The array needs to be computed (just once) before any object A. I thought about having another class B which contains the integer array as a static member, an init() method which would fill this array according to some formula and a static boolean flag initialized (if this variable if true then the init() method would do nothing), but I'm not sure this is the best way to solve my design issue. So my question is, what would be a good design/way to accomplish this ? Thanks in advance.

  • Using jquery, what is the simplest function to post some json data and process a returned json respo

    - by Chris Boesch
    When users click on an element in my webpage, I would like to call a javascript function that reads the values of a few text boxes on the page, wraps their contents as json where the keys are the ids for the text boxes and the values are the contents of each text box, and then posts the resulting json to a url. I would then like the same function to expect back a json response and call another javascript function with the returned json data. Question: What is the best way to write the javascript function to create a json structure from html elements, post the json with jquery, and call another javascript function with the resulting json response from the server?

  • PHP String to Float

    - by John
    I am not familiar with PHP at all and had a quick question. I have 2 variables @pricePerUnit and @invoicedUnits. Here's the code that is setting these to values: $InvoicedUnits = ((string) $InvoiceLineItem->InvoicedUnits); $pricePerUnit = ((string) $InvoiceLineItem->PricePerUnit); If I output this, I get the correct values. Lets say 5000 invoiced units and 1.00 for price. Now, I need to show the total amount spent. When I multiply these two together it doesn't work (as expected, these are strings). But I have no clue how to parse/cast/convert variables in PHP. What should I do?

  • Looking for some help working with premultiplied alpha

    - by user315142
    I am trying to update a source image with the contents of multiple destination images. From what I can tell using premultiplied alpha is the way to go with this, but I think I am doing something wrong (function below). the image I am starting with is initialized with all ARGB values set to 0. When I run the function once the resulting image looks great, but when I start compositing on any others all the pixels that have alpha information get really messed up. Does anyone know if I am doing something glaringly wrong or if there is something extra I need to do to modify the color values? void CompositeImage(unsigned char *src, unsigned char *dest, int srcW, int srcH){ int w = srcW; int h = srcH; int px0; int px1; int px2; int px3; int inverseAlpha; int r; int g; int b; int a; int y; int x; for (y = 0; y < h; y++) { for (x= 0; x< w*4; x+=4) { // pixel number px0 = (y*w*4) + x; px1 = (y*w*4) + (x+1); px2 = (y*w*4) + (x+2); px3 = (y*w*4) + (x+3); inverseAlpha = 1 - src[px3]; // create new values r = src[px0] + inverseAlpha * dest[px0]; g = src[px1] + inverseAlpha * dest[px1]; b = src[px2] + inverseAlpha * dest[px2]; a = src[px3] + inverseAlpha * dest[px3]; // update destination image dest[px0] = r; dest[px1] = g; dest[px2] = b; dest[px3] = a; } } }

  • How to display a border-bottom only if table cells are not empty (CSS)

    - by Polarpro
    Hey there, I've got a Filemaker calculation that generates an HTML page with several tables. If the calculation results in values for certain fields the result would be <table> <tr><td>Example value 1</td></tr> <tr><td>Example value 2</td></tr> ... </table> If the calculation finds no values to be displayed, the result would simply be <table> </table> In the first case, I want to the table to display a border at the bottom (or any other horizontal line); in the second case, I don't want to display a border at the bottom. I cannot find a way to get this done using a CSS... Thanks in adavance :-)

  • Number 0 is not saving to database as a prefix in SQL Server of CHAR data type column

    - by gmhk
    I am trying to insert an value as '019393' into a table with a CHAR(10) column. It is inserting only '19393' into the database I am implementing this feature in a stored procedure, doing some manipulation like incrementing that number by 15 and saving it back with '0' as the prefix I am using SQL Server database Note: I tried CASTING that value as VARCHAR before saving to the database, but even that did not get the solution Code SELECT @fromBSB = fromBSB, @toBSB = toBSB, @type = Type FROM [dbo].[tbl_REF_SpecialBSBRanges] WHERE CAST(@inputFromBSB AS INT) BETWEEN fromBSB AND toBSB SET @RETURNVALUE = @fromBSB IF(@fromBSB = @inputFromBSB) BEGIN PRINT 'Starting Number is Equal'; DELETE FROM tbl_REF_SpecialBSBRanges WHERE Type = @type AND fromBSB = @fromBSB AND toBSB = @toBSB INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@type, CAST('0' + @fromBSB + 1 AS CHAR), @toBSB) INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@inputBSBName, @inputFromBSB, @inputToBSB) END

  • Complex SQL queries (DELETE)?

    - by Joe
    Hello all, I'm working with three tables, and for simplicity's sake let's call them table A, B, and C. Both tables A and B have a column called id, as well as one other column, Aattribute and Battribute, respectively. Column c also has an id column, and two other columns which hold values for A.id and B.id. Now, in my code, I have easy access to values for both Aattribute and Battribute, and want to delete the row at C, so effectively I want to do something like this: DELETE FROM C WHERE aid=(SELECT id FROM A WHERE Aattribute='myvalue') AND bid=(SELECT id FROM B WHERE Battribute='myothervalue') But this obviously doesn't work. Is there any way to make a single complex query, or do I have to run three queries, where I first get the value of A.id using a SELECT with 'myvalue', then the same for B.id, then use those in the final query? [Edit: it's not letting me comment, so in response to the first comment on this: I tried the above query and it did not work, I figured it just wasn't syntactically correct. Using MS Access, for what it's worth. ]

  • Query to select from two different tables

    - by ryan
    I would like to select from two tables and display my result using this query: CREATE TABLE Buy_Table ( buy_id int identity primary key, user_id int, amount decimal (18,2) ); go INSERT INTO Buy_Table (user_id, amount) VALUES ('1', 10), ('1', 8), ('1', 20), ('3', 1), ('2', 2); go CREATE TABLE Sell_Table ( sell_id int identity primary key, user_id int, amount decimal (18,2) ); go INSERT INTO Sell_Table (user_id, amount) VALUES ('1', 10), ('1', 8), ('1', 20), ('3', 3), ('2', 3); go select [user_id], 'Buy' as [Type], buy_id as [ID], amount from Buy_Table union all select [user_id], 'Sell', sell_id, amount from Sell_Table order by [user_id], [ID], [Type] However the above query will return each row of the user_id like this I want to display my result to something like this in a grid: Can this be done in query itself rather manipulating the grid?

  • Multiple sessions or one?

    - by user1314285
    I am using a security token for a form, the form is dynamically built depending on selection through jquery. So the form is called quite a lot and different tokens created every-time. So.. if the same user calls the form 3 times the session would be rewritten? Would it help at all to check if the token exists and not create one unless its empty? or perhaps someone knows of a good way to work with form tokens? If 3 users are on then the token is created 3 times with different values, right? If I check for the token and 3 users are on then the session is created 3 times with the same values?

  • Prove 2^sqrt(log(n))= O(n^a)

    - by user1830621
    I posted a question similar to this earlier, although it seemed like it was much easier. I know the underlying principle of Big-O notation says that to prove that 2^sqrt(log(n)) is O(n^a), there must exist a positive value c for which c(n^a) = 2^sqrt(log(n)) for all values n = N. c*n^a >= 2^sqrt(log(n)) c >= 2^sqrt(log(n)) / n^a This number will always be positive so long as n 0. I suppose I could make N = 1 just to be safe. c = 2^sqrt(log(n)) / n^a N = 1 c*n^a = 2^sqrt(log(n) <= 2^log(n) for all values of n >= 1 Now, I know this is incorrect, because I could just as easily claim that the function 2^sqrt(log(n)) is O(n)...

  • writing terminal output to file

    - by user1551817
    On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!
