How do I Convert Units of Area & Volume Square Feet to Square Yards? 
by Janne Lammi in Home & Garden 

Square feet and square yards are units that measure the area of a flat
surface. A square foot is an exact square that measures one foot on all
four sides, while a square yard measures one yard on all four sides. There
are three feet in every yard, and nine square feet in every square yard.
Use this information to convert the measurements or try the automatic
square yards to square feet converter i


Select smaller square matrices along the diagonal inside a big square matrix in R 
by Russia in Programming Languages 

First of all, if the title of my question is not clear, please go ahead
and edit it! So suppose I have a square matrix. ex = outer(1:4, 2:5, "+") colnames(ex) = paste(rep(c("Subj1",
"Subj2"), each=2), "_", rep("Factor1", each=2), ".",
rep(c("A", "B")), sep="") rownames(ex) = paste(rep(c("Subj1",
"Subj2"), each=2), "_",

How to draw an unfilled square on top of a stream video using a mouse and track the object enclosed in the square automatically in C#? 
by Enar in C & C++ & C# 

I am making an object tracking application. I have used Emgucv 2.1.0.0
to load a video file to a picturebox. I have also taken the
video stream from a web camera. Now, I want to draw an
unfilled square on the video stream using a mouse and then track the object
enclosed by the unfilled square as the video continues to
stream. This is what people ha


How to Find the Square Root of a Number That Doesn't Have a Perfect Square 
by Tom Berthon in Education 

The square root of a number multiplied by itself yields that number. Some
numbers are perfect squares such as 25 (five times five) and 100 (10 times
10). Other numbers are not perfect squares. Although the easiest way to
find the square roots of these numbers is by using a calculator, you may
not always have one nearby when you need it. In these cases, you can figure
the square root yourself by us

How to draw a square on a video and track the object enclosed by the square 
by frozentundra123456 in Programming Languages 

I am doing a Final Year Project to track an object(human) by drawing a
square around a human in a video. I am doing this project in C#
.NET. I asked in a forum about this and they said to use GDI+
and mouse handling (which I have no clue about). Do I have to
do segmentation and then identify the region where the square was drawn, splitting the video to frames perhap

How to Convert Square Inches Per Linear Foot to Square Feet 
by Ingoschi in Hobbies, Games & Toys 

A linear measurement is a measurement taken in a straight line, and a
square measurement is the length multiplied by the width. Many DIY products
and home improvement items are sold in square feet. Items such as carpet,
lino, wood and beading are commonly sold per square foot. Work out the
square footage of an area before ordering the items. Square measurements
are also used on building sites and

How to enumerate unique paths reaching top right (h8) square starting from bottom left (a1) square of a chess board given some move rules? 
by Dmitry in Programming Languages 

I was asked a few weeks ago, to find all the different and unique ways
to reach the top right of a chess board, with x, y > 3, starting from (0,
0), knowing that you can only increase x and y by +1. I still
haven't been able to find algorithms that would explain how to navigate
over a chessboard, so I was wondering if you guys had anything to recommend
? In other words :

How to Measure the Square Feet of Carpet to Square Yards 
by Pseudoics in Home & Garden 

As you measure a room for carpet, the process often requires math formulas
to determine the measurements you need. Multiplying the length and width of
a space will determine the area of the space you wish to carpet. The
process may be more challenging with the conversion of feet to yards. To
calculate the square yards of carpet needed, measure and determine the
square foot area first and then con

How to Convert 1600 Square Feet to Square Meters 
by dantino in Education 

Areas are measured in square units. For many basic geometric shapes, from
triangles to squares to rectangles, multiplying the measurement of one
dimension by that of another dimension calculates its area. For example,
for a rectangle with a length of 6 inches and a width of 3 inches, multiply
the length and width together to determine the area, 18 square inches.
Square feet and square meters are b

How to Convert Square Meters to Square Feet With a Calculator 
by acacio in Education 

Conversion from meter to feet is as simple as knowing that 1 meter =
3.2808399 feet and multiplying the number of meters by 3.2808399. Dealing
with squares is a little trickier. A square is a number (the root number)
times itself. A meter times a meter equals a square meter, so 3 meters x 3
meters = 9 square meters. Converting from square meters to square feet
requires working backward and then fo
