How can we make website using HTML on Punjabi culture?

  1. You should have knowledge of HTML
  2. Or, you can use software where you'll need to drag and drop--you won't have to write HTML in this case.
  3. You need to have data on the Punjabi culture.

Explain Shearing and reflection as a technique of 2d transformation?

ShearingFor shear mapping (visually similar to slanting), there are two possibilities. For a shear parallel to the x axis has x' = x + ky and y' = y; the shear matrix, applied to column vectors, is:

A shear parallel to the y axis has x' = xand y' = y + kx, which has matrix form:

ReflectionTo reflect a vector about a line that goes through the origin, let be a vector in the direction of the line:

To reflect a point through a plane ax + by + cz = 0 (which goes through the origin), one can use , where is the 3x3 identity matrix and is the three-dimensional unit vector for the surface normal of the plane. If the L2 norm of a,b, and c is unity, the transformation matrix can be expressed as:

Note that these are particular cases of a Householder reflection in two and three dimensions. A reflection about a line or plane that does not go through the origin is not a linear transformation; it is an affine transformation.

Write a program parse using brute force technique of top down parsing?

#include<stdio.h>

#include<conio.h>

#include<iostream.h>

void main()

{

int a[30];

clrscr();

int min=10000,temp=0,i,lev,n,noofc,z;

printf("please enter how many number");

cin>>n;

for(i=0;i<n;i++)

a[i]=0;

cout<<"enter value of root";

cin>>a[0];

for(i=1;i<=n/2;i++)

{

cout<<"please enter no of child of parent with value"<<a[i-1]<<":";

cin>>noofc;

for(int j=1;j<=noofc;j++)

{z=(i)*2+j-2;

cout<<"please enter value of child";

cin>>a[z];

}

}

for(i=n-1;i>=n/2;i--)

{

temp=0;

for(int j=i+1;j>=1;j=j/2)

temp=temp+a[j-1];

if(temp<min)

min=temp;

cout<<"temp min is"<<temp<<"\n";

}

For a B tech computer science student which stream is best in MBA?

It all depends on student interest area, whether he wants to go in HR/Marketing/Finance and etc. In my opinion, it is better to go for M.tech OS MS,rahter then going for MBA.

M.tech provide variety of career options for students. MTech program in Computer Science & Engineering takes a unified approach to the design and analysis of computing structures across hardware/software, systems/applications, and theory/experiments.

a wide range of career options are available for m.tech (Cs) student such as:

Real-time and embedded systems / Information Security / Software Engineering

Connected Systems / Entertainment Systems / IT-assisted education / Computer applications in finance and commerce .

Which software is easy to use for building a concept map?

MINDJET MINDMANAGER IS A GOOD CHOICE Mindjet’s technology for dynamic, visual thinking captures, arranges and relates free-form information in a multi-dimensional space. It goes far beyond an everyday outline or the confines of a sheet of paper. In tech-speak, it’s software that brings thoughts and ideas to life on an intuitive, interactive dashboard. Some call it mind mapping. We call it common sense. This is not a new way of thinking. It’s just the first time you’ve been able to see it happen. In fact, we’re wired to work this way. Where the left and right brain play nice—merging logic and creativity to inform decisions, manage priorities and make things happen. Manage information, people and projects—all in one place. Individuals and teams can access, update and share knowledge in static and online environments. You can link and layer images, lists, notes, data, charts, and files in any format—Word, Excel, PowerPoint, PDFs, Web content and the like. You can even assign action items to team members, add icons to highlight key information, and alert others when an automatic update has occurred. It contains virtually every piece of pertinent information for any given project—all in one place. See clearly from any angle. More than a gathering place for thoughts and ideas, the power behind Mindjet is the ability to link and layer information—to build relationships between knowledge and insights from every member on your team. Step back and view the big picture or zoom in on the nitty-gritty details. From any perspective, it’s all about clarity. Take mapping to the max. Collaborate in real time over the Web. With a secure online environment and live Web conferencing, you can easily take mind mapping to another level. Collaborate across time zones with anyone, virtually anywhere. Multiple people can log on to share files, access remote hard drives, live chat and even work on the same maps at the same time. Input, updates and approvals happen instantaneously, right before your eyes. It makes meetings more effective, projects more efficient—and turns the clock back minutes and hours at a time. http://www.mindjet.com/

What is a scripted performance?

something that is planed out like who gonna win a match lik wwe idk if tna and roh is

How do you calculate switching capacity of a switch?

For example you have 24port switch capable of RxTx of 100mbps.

then switching capacity is

24x100= 2400 mbps Rx plus 24x100=2400 mbps Tx .

so a total of 4800mbps which is 4.8gbps.(non blocking architecture)

Rgds,

What are the limitations of finite automata?

The defining characteristic of FA is that they have only a finite number of states. Hence, a finite automata can only "count" (that is, maintain a counter, where different states correspond to different values of the counter) a finite number of input scenarios.

There is no finite automaton that recognizes these strings:

  • The set of binary strings consisting of an equal number of 1's and 0's
  • The set of strings over '(' and ')' that have "balanced" parentheses

The 'pumping lemma' can be used to prove that no such FA exists for these examples.

What is the difference between conventional and software engineering?

Where conventional engineers (chemical, mechanical, etc.) Will work with physical objects, soft ware engineers work with software.

What is the difference between an inductive low pass filter and a capacitive low pass filter?

Where you are measuring. A simple filter will be two elements - a capacitor or inductor and a resistor. A capacitor will tend to "trap" low frequencies. In the case of a lowpass filter made of a capacitor and resistor, the output voltage will be measured across the capacitor. Inductors are the opposite, so the output would be across the resistor.

How interrupts increase the performance of the CPU?

Without interrupts the software must be continuously polling all of the hardware I/O devices to determine their status. Interrupts allow the hardware I/O devices to inform the software when their status has actually changed, thus the software can briefly suspend what it was doing to check the status of the one specific hardware I/O device that sent the interrupt and take care of it then resume what it was doing. Without having to spend all that time polling devices whose status has not changed much less processor time is wasted, thus increasing average performance. Being able to begin handling the device as soon as its status changes instead of having to wait for the next time it is polled, increases realtime performance.

What is the full form of daa?

In a software security regulations context, DAA stands for Designated Accrediting Authority (as per DoDI 8510.01). This is synonymous with "designated approving authority" and "delegated accrediting authority" - terms which were used in prior DoD IA regulations.

There are obviously different definitions for the acronym in other contexts.

What is data view?

Is a logical description of some portion of database that is required by user to perform some task.

What is the advantage of JAD sessions?

JAD sessions enhances the requirement elicitation. It helps in knowing the expectations from the user regarding the software.

Where is the time control unit located on a 1986 Nissan 300ZX?

The Time Control Unit (TCU) is located on the right side above the passenger's right foot.

It's a pain to get to. It's up in the area wher the dash meets the right side. It's mounted in the right side panel/cavity in front of the door. It is not mounted to the firewall.

To get to it do the following:

  1. remove the glove compartment (not required but makes it much easier)
  2. remove the right side kick panel
  3. remove the ECU (REMOVE THE CAR'S BATTERY FIRST)
  4. remove the ECU wiring harness mounting bracket
  5. remove the heater blower

What next after BE Computer?

friend,

you should go for M.Tech after you BE, because this is your core stream or core line.so engineering is best option for your bright future

If you need more information about the admission process ,then check out the websites of some of these universities given below:- BITS , BHU , LOVELY PROFESSSIONAL UNIVERSTY , AMITY UNIVERSITY....etc...
