]]>Thanks for your quick and positive response. I am happy to see your reply. It would be really great thing to connect the IndustryAcademia relationship and feel the gap between Industry and Academic. It will be really a very good platform for young minds. In near future, I will send some more students at your organization definitely and would be happy to invite you in our department for some guest lectures and collaborations to grow together.
Thank you once again for your support.
Looking forward for some kind of collaborations and IndustryAcademia relationship.
Thanks & Regards,

I’ve created a connected graph with 7 nodes and 8 edges. The edges are undirected and unweighted. Distance between two nodes will be measured based on the number of edges separating two vertices. I use the adjacency list to represent the above graph. An effective/elegant method for implementing adjacency lists in Python is using dictionaries. The keys of the dictionary represent nodes, the values have a list of neighbours.
The following screen shot represents representation of the above graph and output shows the result of running Breadth First Search (BFS) algorithm. Can you explain the output? Can you write program in Python ?
Send your suggestions and comments to mehtaashwin@vissicomp.in
Best answer will be rewarded.

We can set up a matrix for any sequence of transformations as a composite transformation matrix by calculating the matrix product of the individual transformations. Forming products of transformation matrices is often referred to as a concatenation, or composition, of matrices.
Translation:
If two successive translation vectors (tx1, ty1 ) and (tx2, ty2) are applied to a coordinate position P, the final transformed location P’ is calculated as
P’= T (tx2, ty2) * {T (tx1,ty1) * P}
= {T (tx2, ty2) * T(tx1,ty1)} * P
where P and P’ are represented as homogeneouscoordinate column vectors. We can verify this result by calculating the matrix product for the two associative groupings Also, the composite transformation matrix for this sequence of translation is
T (tx2,ty2) * T(tx1,ty1) = T( tx1+tx2 , ty1+ty2)
which demonstrates that two successive translation are additive.
Rotation:
Two successive rotations applied to point P produce the transformed position
P’ = R(θ_{2}) *{R(θ_{1}) *P}
P’= {R(θ_{2}) * R(θ_{1})} * P
By multiplying the two rotation matrices, we can verify that two successive rotations are addictive.
R(θ_{2})* R(θ_{1}) = R(θ_{1 + }θ_{2})
so that the final rotated coordinates can be calculated with the composite rotation matrix as
P’=R(θ_{1 }+ θ_{2}) * P
Scaling:
Concatenating transformation matrices for two successive scaling operations produces the following composite scaling matrix:
The resulting matrix in this case indicates that successive scaling operations are multiplicative. That is, if we were to triple the size of an object twice in succession, the final size would be nine times that of the original.
General FixedPoint Scaling
Above figure illustrates a transformation sequence to produce scaling with respect to a selected fixed position (x_{f} , y_{f}) using a scaling function that can only scale relative to the coordinate origin.
Concatenating the matrices for these three operations produces the required scaling matrix:
The transformation is automatically generated on systems that provide a scale function that accepts coordinates for the fixed point.
General Scaling Directions
Parameters s1 and s2 scale objects along the x and y directions. We can scale an object in other directions by rotating the object to align the desired scaling directions with the coordinate axes before applying the scaling transformation.
To accomplish the scaling without changing the orientation of the object, we first perform a rotation so that the directions for s, and s2 coincide with the x and y axes, respectively. Then the scaling transformation is applied, followed by an opposite rotation to return points to their original orientations.
The composite matrix resulting from the product of these three transformations is
Concatenation Properties
Matrix multiplication is associative. For any three matrices, A, B, and C, the matrix product A *B *C can be performed by first multiplying A and B or by first multiplying B and C:
A*B*C= (A*B)*C = A*(B*C)
Therefore, we can evaluate matrix products using either a lefttoright or a right to left associative grouping. On the other hand, transformation products may not be commutative: The matrix product A. B is not equal to B – A, in general. This means that if we want to translate and rotate an object, we must be careful about the order in which the composite matrix is evaluated . For some special cases, such as a sequence of transformations all of the same kind, the multiplication of transformation matrices is commutative. As an example, two successive rotations could be performed in either order and the final position would be the same. This commutative property holds also for two successive translations or two successive scaling. Another commutative pair of operations is rotation and uniform scaling (s_{x },s_{y}).
OTHER TRANSFORMATIONS
Basic transformations such as translation, rotation, and scaling are included in most graphics packages. Some packages provide a few additional transformations that are useful in certain applications. Two such transformations are reflection and shear.
Reflection
A reflection is a transformation that produces a mirror image of an object. The mirror image for a twodimensional reflection is generated relative to an axis of reflection by rotating the object 180″ about the reflection axis.
Reflection about the line y = 0, the x axis, is accomplished with the transformation matrix
A reflection about the y axis flips x coordinates while keeping y coordinates the same. The matrix for this transformation is
Reflection about origin
We flip both the x and y coordinates of a point by reflecting relative to an axis that is perpendicular to the xy plane and that passes through the coordinate origin. This transformation, referred to as a reflection relative to the coordinate origin, has the matrix representation
Reflection axis as the diagonal line y = x
If we chose the reflection axis as the diagonal line y = x (Fig. 520), the reflection matrix is
Reflection about the diagonal y = x
To obtain a transformation matrix for reflection about the diagonal y = x, we could concatenate matrices for the transformation sequence:
Reflections about any line y = mx _{ }+ b in the xy plane can be accomplished with a combination of translaterotatereflect transformations. In general, we first translate the Line so that it passes through the origin. Then we can rotate the line onto one of the coordinate axes and reflect about that axis. Finally, we restore the line to its original position with the inverse rotation and translation transformations.
Shear
A transformation that slants the shape of the object is called shear transformation. Two common shearing transformations are used.
X shear
The X shear preserves the y coordinates, but changes the x values which causes vertical lines to tilt right or left.
Any real number can be assigned to the shear parameter sh_{x}. A coordinate position (x, y) is then shifted horizontally by an amount proportional to its distance (y value) from the x axis (y = 0). Setting sh_{x} to 2, for example, changes the square in Fig. 523 into a parallelogram. Negative values for sh_{x} shift coordinate positions to the left. We can generate xdirection shears relative to other reference lines with
Y Shear
The y shear preserves the x coordinates, but changes the y values which causes horizontal lines to transform into lines which slope up or down.
A ydirection shear relative to the line x = x_{ref} is generated with the transformation matrix

]]>Python is one of the most commonly used programming languages. For the past five years, Python has held the number one position as the “most popular coding language.”
Python owes a great deal of its flexibility to the many programming environments and frameworks that make the development of specific applications quick and easy.
For example, web developers can turn to frameworks like Django or Flask, which let you focus on writing the app or site rather than get bogged down by tedious legwork.
DJANGO, A HIGHLEVEL PYTHON WEB FRAMEWORK, IS FLATOUT AMAZING.
The ability to use Django is perhaps one of the biggest advantages of learning Python.
The Django framework lets you model your domain and code classes.
Now you can focus your efforts on your user interface.
Update admin.py file with following line of code:
Admin.site.site_header=’text you want to change in header of the admin site’
Or
Change url.py file:
Admin.site.site_header=”header text”
