from:"Santanu"

Dear Nils,
   Thank you so much for your comments.
I consider Matrix E=[I,M1], where I is identity matrix.
Then reduction of E took 100 seconds. Hence I am not
going any advantage.

Regards,
Santanu

Re: [sage-devel] Unimodular transformation matrix of LLL algorithm

Dear Martin,
Thank you so much. It works!
Can we make it faster?
It took 17 seconds for my problem but
M1.LLL() took only 3 seconds. Of course I understand we
are calculating extra matrix U.

Thanks again for your help.

Regards,
Santanu

[sage-devel] Unimodular transformation matrix of LLL algorithm

Dear all,
   I have a matrix M1 with integer entries with 90 rows and 6 columns.
After applying LLL algorithm of M1, I get M2=M1.LLL(). I want to get
corresponding unimodular transformation matrix T such that
T*M1=M2. We can find T by
T=M2*M1.pseudoinverse() or T== M1.solve_left(M2), but determinant of T
becomes 0 i.e.,  T.det()=0.
I want T.det()=1.

Best regards,
Santanu

[sage-support] Reduction over Ideal

2020-08-05 Thread Santanu Sarkar

Dear all,
Consider ideal I= over the binary field GF(2).
Then (x2).reduce(I) gives x2. I want it to be x0*x1.
In fact , I want this kind of reduction always should give quadratic
polynomial
(I know that this is possible for my problems).

[Wien] Band structure calculation

2019-12-09 Thread Santanu Pathak

  In an calculation with PBE xc, energy values are coming without any
warning and the error files are generating but are completely empty.
Whereas band structure calculation is being interrupted due to lapw1 error,
shown in follow.

LAPW1 - Error
0.140u 0.015s 0:00.15 100.0%0+0k 0+5136io 0pf+0w


1. Why these empty error files are generated at all?
2. How can band structure be calculated in this case?

Thank you.

*Santanu *

Regarding array

2019-08-12 Thread Santanu

While exploring nim, I came to know that you cannot create an array during 
dynamically. The size of the array must be known at compile time. There are a 
few work around as i have found in the previous thread i ask or one can use 
static[int] while using array within a function or object. Why was the array 
designed this way in nim? Most major static language can create dynamically. Is 
seq the answer to this problem? I am assuming seq is like a Array in java or 
vector in c++ where the memory doubles after hitting a certain threshold. What 
is the performance difference between array and seq?

One more question ... How do i pass a matrix to function?


proc (mat: var openArray[seq[int]]) = discard


Run

This is working for a 2d seq, but if the rank increases it will be quite 
cumbersome. Is there a more elegant way to pass matrix to a function?

[gmx-users] cmap error while making tpr file from dcd file

2019-06-13 Thread Santanu Santra

hey users,
While I'm trying to calculate some properties in gromacs
from dcd files (NAMD), I followed the protocol in generating xtc file from
vmd by loading psf and pdb files, and by grompp engine using a similar mdp
file equivalent to my NAMD configuration file, I got CMAP error as
follows:::
===
ERROR 1 [file xxx_350k.top, line 2163]:
  Unknown cmap torsion between atoms 8 10 12 27 29
==
And this is the first line in CMAP category of my xtc file, so I believe
it's unable to read CMAP part. Any kind of suggestion is highly appreciated
which can help me to get rid of the error or to generate tpr file from dcd
(NAMD) files.

Thanks in advance
Regards

Santanu Santra

 So, there will be a single generator for a place. But here it is

[sage-support] How to define variables over integer

2019-05-08 Thread Santanu Sarkar

I know how to define variables over BooleanPolynomialRing.
This is as follows.

n=4
V=BooleanPolynomialRing(n+1,['z%d'%(i) for i in range(n+1)] )
V.inject_variables()

Can we define similar code over integers (ZZ) or rationals (QQ)?
Also I want to store variables in an array like Z=[z0,z1,z2,z3]
but it should be automatic. I will change only n.

Re: [Wien] WARNING in CHARGED CELL calculation

I am calculating energy and hyperfine parameters for oxide. I have
performed a neutral cell calculation and then due to performing, made the
required changes in input files (1. Removed 1 electron, therefore reduced
:NE by 1 in .in2c file, and 2.  Edited 1st line in .inm file by BROYD
-1.0   YES). For one particular structure of the oxide, the charged cell
calculation shows no warning and DOS calculation is meaningful. But any
calculation with very little change in atomic positions is showing WARNING
in energy and message in .scf file is following:

:WARN  :CHARGED CELL with  -1.000
an energy correction like C Q**2/(L eps) is not included

error in the scf run and DOS, band structure, optical properties are being
studied. But after following all the steps for Electron Density plot, *a
message 'DIR WRONG'* is coming in *x lapw5* as below.

[image: image.png]
Therefore electron density plot is not formed as shown below.

How can this problem be solved? Kindly let me know if any further detail is
needed about the scf run or structure for solving the problem. Thank you.

Re: Nim VS Code autocompletion

2019-02-19 Thread Santanu

Thanks guys for your help, solved the problem. Apparently while installing the 
compiler manually something must have gone wrong with koch tools. Although nim 
was added to the path, but nimble and nimsuggest was not. Did a fresh install 
using chooseNim and now works fine.

Nim VS Code autocompletion

2019-02-19 Thread Santanu

Hi, Completely new to nim. I install nim on my arch Linux machine using "" sudo 
pacman -S nim", works fine, install the nim package in vs code, still works 
like gem; gives useful snippet of info for each proc. But the version of nim in 
the repository is 0.18.0, so couldn't install any third party library like 
jester. Uninstall it, download the binaries for the latest version from the 
official website also nimble. Installed it with the direction given, added path 
to .bachrc. Works fine, But no code completion now in vs code. I think the path 
to nimsuggest in not added. Tried to add the dir of nimsuggest inside 
nim-0.19.4 to path. Does not work. Plz Help!

[gmx-users] Bad contact error for gromacs 5.0.4 but running in 4.6.5

2018-09-04 Thread Santanu Santra

hi all,
   I have two sets of solutions containing solute 0.5 M and 2M in
water. While I was simulating 2 M solution this was running successfully
without error in gromacs 4.6.5 version but getting error in gromacs 5.0.4
version with the same input gro file and same mdp file.

The error in gromacs 5.0.4 is :

Polak-Ribiere Conjugate Gradients:
   Tolerance (Fmax)   =  1.0e+03
   Number of steps=  500
   F-max =  9.56087e+02 on atom 432
   F-Norm=  1.37462e+02

step -1: Water molecule starting at atom 1236 can not be settled.
Check for bad contacts and/or reduce the timestep if appropriate.

WARNING: Listed nonbonded interaction between particles 1121 and 1135
at distance 2.693 which is larger than the table limit 2.000 nm.

This is likely either a 1,4 interaction, or a listed interaction inside
a smaller molecule you are decoupling during a free energy calculation.
Since interactions at distances beyond the table cannot be computed,
they are skipped until they are inside the table limit again. You will
only see this message once, even if it occurs for several interactions.

IMPORTANT: This should not happen in a stable simulation, so there is
probably something wrong with your system. Only change the table-extension
distance in the mdp file if you are really sure that is the reason.

[gmx-users] gmx convert-tpr tool is not found but tpbconv_mpi is present in gromacs 5.0.4

2018-07-06 Thread Santanu Santra

Hi all,
 I have installed gromacs 5.0.4 in a parallel cluster. While I was
serching for gmx convert-tpr tool to extend my simulation that has been run
previously upto 15 ns (I want to continue the simulation upto 100 ns).
According to gromacs documentation tpbconv_mpi tool is removed from gromacs
5.0. version and this is replaced by gmx convert-tpr tool. But in my
bin directory there is nothing in the name of  gmx convert-tpr or in
similar name, but I found tpbconv_mpi . I also tried with that tool to
extend but it is showing error .

I tried the command==
tpbconv_mpi -s md_nvt -o md_nvt_25.tpr -extend 1

I got 
GROMACS:  gmx tpbconv, VERSION 5.0.4
Executable:   /opt/gromacs-5.0.4/bin/gmx_mpi
Library dir:  /opt/gromacs-5.0.4/share/gromacs/top
Command line:
  tpbconv_mpi -s md_nvt -o md_nvt_25.tpr -extend 1

This tool has been removed from Gromacs 5.0. Please see
  http://www.gromacs.org/Documentation/How-tos/Tool_Changes_for_5.0
for ideas how to perform the same tasks with the new tools.
===

I am confused with two contrary statements.
(1) If tpbconv_mpi tool is removed from gromacs 5.0.X version, then how it
is present in my bin directory and also it is not working
(2) why  gmx convert-tpr tool is absent in my bin directory. As all other
tools are available in my bin directory.


Any help or suggestion is highly accepted. Thanks in advance.

how to pass constant parameter to Init() function of UDAF

2017-08-14 Thread Santanu Chatterjee

I am trying to develop a UDAF which takes three parameters. SQL syntax
would look like this :

select myudaf(col1, 1, 100) from mytab;

Here col1 is from table mytab and of type numeric (double/int etc.). The
other two parameters are constants. The third parameter determines memory
allocation for intermediate results. Therefore, I need to access it from
Init() function. Here is how I developed my update and init functions :

void myUDAFInit(FunctionContext *ctx, StringVal *dst);
void myUDAFUpdate(FunctionContext *ctx, const DoubleVal& d, const IntVal&,
const IntVal&, StringVal* result);

Also, I am defining my UDAF like this :

create aggregate function myUDAF(double, int, int) returns... ;

However, when I try to access function arguments in my Init() function, it
says the arguments are non-constant. Is there a different way to define
constant arguments?

Thanks in Advance.

GWT DataGrid background colour for rows

2017-05-30 Thread Santanu Banerjee

I am trying to apply background colour to some rows dynamically based on 
some program logic, but I can see that the colour is disspearing on any 
further row selection.
I used two approaches to change the colour.
1) baseGrid.getRowElement(i).getCells().getItem(0).addClassName();
2)TableCellElement cell = 
grid.getRowElement(i).getCells().getItem(colIndex); 
cell.getStyle().setProperty("background", "#DD");

Could you please suggest any alternative ways I can do it. so that the 
background colour of the rows do not change on any further row selection?

Thanks,
Santanu

[akka-user] Using Akka for Data Synchronization Use Case

2017-05-07 Thread Santanu Dey

*Please suggest if Akka can be used for the following use case:*


I have to run an application for two different user groups one from the 
Intranet and another from the Internet. 

The company policy requires me to run this applications from two different 
hosting sites 

Each site would contain its own DB, App and Web server resources. 

However the application copy on either side should be consistent with 
respect to data. 

Only communication between these two layers are allowed via a message 
queue. 

*Questions*

   1. Can Akka be used on both sides application layer to solve the data 
   consistency problem on either copies of the application?
   2. Can Akka make use of the message queue for communicating between the 
   hosting site A to hosting site B?

Thanks

[polymer-dev] Re: How to distinguish between structural changes to array made in parent element vs property changes to an item of array made in child element observer?

2017-03-04 Thread Santanu Basu

I could also see the log output being reasonable.  But that gets at the 
question behind the question, which is this:  How can I observe a change 
caused by an actual edit of an item of the list, and not a reassignment of 
the data objects to the element instances that is causes by things like 
unshift, sort, or filter?  That distinction is really what I'm interested 
in.

[polymer-dev] How to distinguish between structural changes to array made in parent element vs property changes to an item of array made in child element observer?

2017-03-04 Thread Santanu Basu

I have posted this in another form on SO 
(http://stackoverflow.com/questions/42565640/how-to-distinguish-between-structural-changes-to-array-made-in-parent-element-vs)
 
and in the 2.0-preview branch slack channel, but I know they are heads down 
with the upcoming release, so hopefully somewhere in the broader group here 
will have insight to share.

The TL;DR question: how many times should the observer, defined in 
editor-element.html log to console for the following sample code: 
https://plnkr.co/edit/iTZqM4GwpASEqQgtRGEk?  I would have expected 4, but 
it actually happens 6 times.

More details: the elements are a list element which, using dom-repeat, 
renders a list of todos, and each todo is rendered by an instance of an 
editor element.  The data is a list of todo objects, each of which has a 
primitive property called description.  First, two todo objects are pushed 
onto the list.  Then the first todo object's description property is 
edited.  Then a third todo object is unshifted (not pushed) onto the list. 
 The data binding is defined two way between the items inside the 
dom-repeat of the list element and the todo property of the editor element. 
 In other words, the binding is made at the object, not the property.  The 
editor element defines an observer on "todo.description", printing a 
message to the console each time an observation is made.

[sage-support] Lattice reduction over polynomial lattice

Dear all,
   I have polynomial lattice over a finite field. So each component of the
vectors v_1, v_2, v_3 are polynomials over a finite field say F_11. Hence
v_1=(f_1(x), f_2(x), f_3(x)),  v_2=(g_1(x), g_2(x), g_3(x)) and
v_3=(h_1(x), h_2(x), h_3(x)). Here norm is the maximum degree of each
 component. Does there exist LLL algorithm for this lattice in Sage?

[j-nsp] Measure transit traffic to specific destination

2016-12-29 Thread Santanu Mandal

Dear all,
I want to measure traffic bandwidth consuming for a specific destination IP
from My Orzanization. Say how much is bandwidth is consumed for destination
x.x.x.x out of total bandwidth in my ISP link.

I have configured S-flow, but there I can see total amount of traffic
transfered over a period of time. But My concern is, data transfer rate
confumed for this destination, not tootal amount of data.

It would be gratfull if you can suggest a tool for this purpose or how to
approach to achive this.



Thanking you
 in advance

Hello Peter. Thank you for this new feature, I surely test this very soon from 
nightly build.

Regarding selecting multiple rows, custom bead extending which bead or adding a 
new bead you're referring to?

Description: 
(This issue once discussed in Apache mailing-list at: 
http://apache-flex-users.246.n4.nabble.com/Updating-className-td12217i20.html)

*Requirement*
Updating UI components' styles at runtime. If possible, updating their 
_className_ property at runtime and see it's effect without refreshing browser.

*What we have*
Updating _className_ property to any component do not works.

*Workaround*
Using _BindableCSSStyle_ to update any given style at runtime and see it's 
effect.

*Result*
_BindableCSSStyle_ API not able to update all it's properties at runtime. 
Furthermore, it only shown partially working in SWF, HTML version completely 
broken.

*Expected*
Class able to change all it's public properties at runtime in both HTML and SWF 
run.


h3. Observation 
As suggested in mailing-list (link given above), _BindableCSSStyle_ used in 
*FlexJSStore* example project that supplied within SDK bundle, in 
{{/flexjs/FlexJSStore/productsView/ProductCatalogThumbnail.mxml}} page. I 
tested, it does updates "border" property to a component at runtime. 

It does not updates all other properties at rumtime though (in SWF, HTML 
version do not works at all), i.e. backgroundColor.

I tested with a simple example, by modifying the "ProductCatalogThumbnail.mxml 
file only:

{code}






   

...
private function rollOverHandler(event:MouseEvent):void
{
borderStyles.borderColor = "#ff";
borderStyles.backgroundColor = "#00";
//style["dropShadowEnabled"] = true;
buttons.visible = true;
}

Setting up _backgroundColor_ property in _rollOverHandler()_ never worked, as 
an example.

Description: 
(This issue once discussed in Apache mailing-list at: 
http://apache-flex-users.246.n4.nabble.com/Updating-className-td12217i20.html)

*Requirement*
Updating UI components' styles at runtime. If possible, updating their 
_className_ property at runtime and see it's effect without refreshing browser.

*What we have*
Updating _className_ property to any component do not works.

*Workaround*

effect.

*Result*
_BindableCSSStyle_ API not able to update all it's properties at runtime. 
Furthermore, it only shown partially working in SWF, HTML version completely 
broken.


h3. Observation 
As suggested in mailing-list (link given above), _BindableCSSStyle_ used in 
*FlexJSStore* example project that supplied within SDK bundle, in 
{{/flexjs/FlexJSStore/productsView/ProductCatalogThumbnail.mxml}} page. I 
tested, it does updates "border" property to a component at runtime. 

It does not updates all other properties at rumtime though (in SWF, HTML 
version do not works at all), i.e. backgroundColor.

I tested with a simple example, by modifying the "ProductCatalogThumbnail.mxml 
file only:

{code}

   

...
private function rollOverHandler(event:MouseEvent):void
{
borderStyles.borderColor = "#ff";
borderStyles.backgroundColor = "#00";
//style["dropShadowEnabled"] = true;
buttons.visible = true;
} 
{code}

Setting up _backgroundColor_ property in _rollOverHandler()_ never worked, as 
an example.

[jira] [Created] (FLEX-35215) [FlexJS] Responsive VerticalColumnLayout

Santanu Karar created FLEX-35215:


 Summary: [FlexJS] Responsive VerticalColumnLayout
 Key: FLEX-35215
 URL: https://issues.apache.org/jira/browse/FLEX-35215
 Project: Apache Flex
  Issue Type: Improvement
Affects Versions: Apache FlexJS 0.8.0
Reporter: Santanu Karar


*Requirement*
It'd be great if columns wrapped as rows if browser resized, at runtime.

*Present state*
A simple code as following creates 2 columns with fixed widths. 
{code}












{code}
We change the VerticalColumnLayout's _numColumns_ property change only once 
while starting the application but runtime.

*Expectation*
When browser resized, if it's visible width became less than 500px (per above 
code example), the second column came down below the first column, to form as a 
row of item.

At present {{DataGrid.selectedIndex}} is a read-only property. We probably need

Hello Alex,

I've updated the patch file, sorry for the trouble. 

Yes, after adding that default property metadata, I did build it's 'swc' and 
tested locally. This worked fine after that addition. I noticed I thrown by the 
said error when my MXML implementation was almost empty even:
{code}
http://ns.adobe.com/mxml/2009;
xmlns:js="library://ns.apache.org/flexjs/basic">

{code}

I'm not sure about what binding expression problem you've noticed, though.

Description: 
(I've took the _DataGrid_ example that supplied within the nightly build of 
0.8.0 FlexJS SDK bundle, and I tried all my tests in that project only)

h3.Requirement

Binding is a strong feature in Flex technology. As an user I also do expect 
that FlexJS will also empowers us with the same strength developing projects. 
While testing _DataGrid_ example that supplies within SDK bundle, I noticed 
that pay-as-you-go view only available but no actual run-time data binding (as 
far I tested); which is the strength that I was talking about. Is run-time 
data-binding (by any _beads_ or any other way) to DataGrid component is at all 
available yet? 

In the following tests I tried to update one row object's (_Product_) one 
particular field (_image_) value, to see it's change in row renderer, at 
run-time. 
I also tried to add or delete an item to it's _dataProvider_ collection to see 
their changes in DataGrid UI.

h3.Actual Result

Run-time data update to collection list not affecting to DataGrid UI.

h3.How I Tested

I've attached the source ZIP that supplied within SDK bundle and I modified few 
codes to test my requirement.

The example consists of a DataGrid, and few buttons as follows:
- Replace Array - replace the entire model with a new Array
- Update Entry - Update the image for the first entry
- Add Entry - Add a new entry to the end of the list
- Remove Entry - Remove the first entry
- Refresh - this recreates the array and saves it to the model. This forces the 
DataGrid to update by the same method as Replace Array

"Replace Array" and "Refresh" worked fine. "Refresh" is a possible workaround 
for data update to grid UI, but it is inefficient for a real application. The 
other buttons did not cause DataGrid UI to update. The places which I've 
changed as follows. 

*Product.as*
{code}
// since I was trying to update one field at least to DataGrid UI, I added 
get/set methods to the _image_ field
private var _image:String;

[Bindable(event="imageChanged")]
public function get image():String
{
return _image;
}

public function set image(value:String):void
{
if (value != _image)
{
_image = value;
dispatchEvent(new Event("imageChanged"));
}
}
{code}

*MyInitialView.mxml*
{code}
// Replacing or recreating the collection list
private function replaceArray():void
{   
// Only this part worked when SimpleBinding used rather than 
ConstantBinding
ProductsModel(applicationModel).productList = new ArrayList([new 
Product("ps220","Weejets",35,190,"assets/smallorangerect.jpg")]);

writeStatus();
}

// Update an entry to the collection
private function updateEntry():void
{
// This part not working or updating to DataGrid UI either
/*ProductsModel(applicationModel).productList.source[1] = tmp;
ProductsModel(applicationModel).dispatchEvent(new 
Event("propertyChange"));*/

// This part not working or updating to DataGrid UI
var tmp:Product = 
ProductsModel(applicationModel).productList.getItemAt(0) as Product;
tmp.image = "Modified Text";

writeStatus();  
}

// Adding an item to the collection list
private function addEntry():void
{
// Add a new entry to the list
idCounter++;
ProductsModel(applicationModel).productList.addItem(new 
Product("product" + idCounter, "Added" + idCounter, 35, 190, 
"assets/smallorangerect.jpg"));

writeStatus();
}

// Removing an item from the collection list
private function removeEntry():void
{
// remove the first item
ProductsModel(applicationModel).productList.removeItemAt(0);

writeStatus();
}

// Refreshing the collection to datagrid
private function refresh():void
{
// force an update setting the model to the same value it already has.  
See replaceArray()

// this was insufficient to trigger the update:
// ProductsModel(applicationModel).productList = 
ProductsModel(applicationModel).productList;

// Since there was NO refresh logic to ArrayList or DataGrid component, 
we only do a brute refresh to the list
var oldArray:ArrayList = ProductsModel(applicationModel).productList;
var newArray:ArrayList = new ArrayList();
var index:int;
for (index = 0; index < oldArray.length; index++) {
newArray.addItem(oldArray.getItemAt(in

Description: 
(I've took the _DataGrid_ example that supplied within the nightly build of 
0.8.0 FlexJS SDK bundle, and I tried all my tests in that project only)

h3.Requirement

Binding is a strong feature in Flex technology. As an user I also do expect 
that FlexJS will also empowers us with the same strength developing projects. 
While testing _DataGrid_ example that supplies within SDK bundle, I noticed 
that pay-as-you-go view only available but no actual run-time data binding (as 
far I tested); which is the strength that I was talking about. Is run-time 
data-binding (by any _beads_ or any other way) to DataGrid component is at all 
available yet? 

In the following tests I tried to update one row object's (_Product_) one 
particular field (_image_) value, to see it's change in row renderer, at 
run-time. 
I also tried to add or delete an item to it's _dataProvider_ collection to see 
their changes in DataGrid UI.

h3.Actual Result

Run-time data update to collection list not affecting to DataGrid UI.

h3.How I Tested

I've attached the source ZIP that supplied within SDK bundle and I modified few 
codes to test my requirement. The places which I've changed as follows. 

*Product.as*
{code}
// since I was trying to update one field at least to DataGrid UI, I added 
get/set methods to the _image_ field
private var _image:String;

[Bindable(event="imageChanged")]
public function get image():String
{
return _image;
}

public function set image(value:String):void
{
if (value != _image)
{
_image = value;
dispatchEvent(new Event("imageChanged"));
}
}
{code}

*MyInitialView.mxml*
{code}
// Upon a button click I tried to change collection data at run-time to make 
effect in DataGrid UI
private function onButtonClicked():void
{
// 1. This part not working or updating to DataGrid UI
/*var tmp:Product = 
ProductsModel(applicationModel).productList.getItemAt(1) as Product;
tmp.image = "Modified Text";*/

// 2. This part not working or updating to DataGrid UI either
/*ProductsModel(applicationModel).productList.source[1] = tmp;
ProductsModel(applicationModel).dispatchEvent(new 
Event("propertyChange"));*/

// 3. Only this part worked when *SimpleBinding used instead of 
ConstantBinding*
ProductsModel(applicationModel).productList = new ArrayList([new 
Product("ps220","Weejets",35,190,"assets/smallorangerect.jpg")]);
}

...

// DataGrid ConstantBinding bead replaced with SimpleBinding



...
{code}

I also created a new MXML based _DataItemRenderer_ component to see if binding 
is working anyway: *ProductItemRendererMXML.mxml*; But it didn't worked either. 

I discussed this at dev mailing-list 
(http://apache-flex-development.247.n4.nabble.com/Why-same-files-exists-in-multiple-places-td56983.html)
 where Alex suggested that a chain of specific beads usage may help this 
feature, but he wasn't sure if such beads already developed or not. 

Is there any such beads or procedure already available, or, in-development?
