Streamlining Design With Real World Vibration AnalysisSOLIDWORKS
Mechanical designers often use vibration simulation as a timesaving and cost-efficient alternative to the traditional approach of building, testing, modifying, and retesting their designs. By identifying the factors that influence the response to a dynamic load in a computer model, designers have the data needed to make the right improvements before they even cut a single piece of metal. In addition to greatly decreasing the number of actual prototypes required, vibration analysis also significantly reduces the costs involved.

Short-term load forecasting with using multiple linear regression IJECEIAES
In this paper short term load forecasting (STLF) is done with using multiple linear regression (MLR). A day ahead load forecasting is obtained in this paper. Regression coefficients were found out with the help of method of least square estimation. Load in electrical power system is dependent on temperature, due point and seasons and also load has correlation to the previous load consumption (Historical data). So the input variables are temperature, due point, load of prior day, hours, and load of prior week. To validate the model or check the accuracy of the model mean absolute percentage error is used and R squared is checked which is shown in result section. Using day ahead forecasted data weekly forecast is also obtained.
In these case studies, the answers of the cases are derived out. These slides will enable you to get full understanding of the marketing and trading Concept.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

15. Average Rate of Change
The easiest example for the average rate of change is speed. Speed is
simply distance covered by a body in a particular amount of time. The
formula for speed is:
Speed = Distance Covered/Total Time Taken
16. Let’s say a body movies in a straight line from a point A
to a point B. Point A is 100 Kilometers away and Point B
is 150 Kilometers away, then the distance that the body
has covered comes out to be 150 – 100 = 50 km. Suppose,
the body was at Point A at 04:30 PM and reached Point B
at 08:30 PM. The time taken by the body to cover the
distance comes out to be 4 hours. Hence, if we want to
calculate the average rate of change of distance with
respect to time, then it simply comes out to be 50/4 i.e.
12.5 km per hour.
Another very good example of average rate of change is
when you find the slope of a line. The slope of a line is
nothing but the change in Y coordinates with respect to
the change is the X coordinates. If a line crosses two
points with coordinates (x1, y1) = (2, 2) and (x2, y2) = (3,
0), then the slope of the line is (y2-y1)/(x2-x1) = (0-2) /
(3-2) = -2/1. Hence, the average rate of change in the Y
coordinates with respect to the X coordinates a.k.a. the
slope of the line is -2.
17. Practical Applications of the Average
Rate of Change
As described before, average rate of change is used to measure the speed of
an object undergoing motion. An advanced level of the formula is used in
various astronomical equations pertaining to rocket science and space travel.
The equation is used to measure the rate of a chemical reaction in chemistry.
This application of average rate of change is very useful in Chemical
Engineering Calculations.
The formula is used in various behavioral calculations relating to
management and the human psyche.
A good application in real life can be found in predicting your electricity bill.
If you have an idea of the average rate in which electricity is consumed in
your household, then you can predict your electricity bill for a month. These
fundamentals are used in various devices that help you monitor your
electricity bill.
18. Instantaneous Velocity
Suppose we drop a tomato from the top of a 100 foot building and time
its fall.
How long did it take for the tomato to drop 100 feet? (2.5 seconds)
How far did the tomato fall during the first second? (100 – 84 = 16 feet)
How far did the tomato fall during the last second? (64 – 0 = 64 feet)
19. Maxima and Minima of functions
A real-valued function f defined on a domain X has
a global (or absolute) maximum point at x∗ if f(x∗) ≥ f(x) for all x in X.
Similarly, the function has a global (or absolute) minimum
point at x∗ if f(x∗) ≤ f(x) for all x in X. The value of the function at a
maximum point is called the maximum value of the function and the
value of the function at a minimum point is called the minimum value of
the function.
20. Applications in real life and business
of Maxima and Minima of functions
Maxima and minima pop up all over the place in our daily lives. They can be
found anywhere we are interested in the highest and/or lowest value of
a given system; if you look hard enough, you can probably find them just
about anywhere! Here are just a few examples of where you
A meteorologist creates a model that predicts temperature variance with
respect to time. The absolute maximum and minimum of this function over
any 24-hour period are the forecasted high and low temperatures, as
later reported on The Weather Channel or the evening news.
The director of a theme park works with a model of total revenue as a
function of admission price. The location of the absolute maximum of this
function represents the ideal admission price.
21. An actuary works with functions that represent the probability of various negative events occurring. The
local minima of these functions correspond to lucrative markets for his/her insurance company – low-risk,
high-reward ventures.
It is used in Chemistry. We have used the maxima of wave function and radial probability distribution
functions to determine where an electron is most likely to be found in any given orbital.
A NASA engineer working on the next generation space shuttle studies a function that computes the
pressure acting on the shuttle at a given altitude. The absolute maximum of this function represents the
pressure that the shuttle must be designed to sustain.
22. Anti-derivatives: the Indefinite Integral
Antiderivatives are related to definite integrals through the fundamental
theorem of calculus: the definite integral of a function over an interval is
equal to the difference between the values of an antiderivative evaluated
at the endpoints of the interval.
23. Applications in real life and business
in Anti-derivative: Indefinite Integral
To determine the rate of a chemical reaction and to determine some
necessary information of Radioactive decay reaction.
Electric Charges have a force between them that varies depending on the
amount of charge and the distance between the charges. We use
integration to calculate the work done when charges are separated.
24. To calculate the center of mass, center of gravity and mass moment of inertia of vehicles, satellites, a
tower and basically every other building or structure which you can imagine.
To calculate the velocity and trajectory of a satellite while placing it an orbit like at exactly which point you
need to give how much thrust to get the desired trajectory.
To study of the spread of infectious disease — relies heavily on calculus. It can be used to determine how
far and fast a disease is spreading, where it may have originated from and how to best treat it.
25. Area and Definite Integral
The area of a flat, or plane figure is the number of unit squares that can
be contained within it. The unit square is usually some standard unit, like
a square meter, a square foot, or a square inch.
26. Applications in real life and business in
Area and Definite
Parking lots are sized depending on the area of the associated building.
Building lobbies are designed to provide enough area for the people who
will be passing through, and lingering.
Airports are designed to provide enough area for the planes to get to the
gates without bumping in to each other.
Ports and docks are designed so ships can be tied up without bumping
into each other.
27. Consumers and Producers Surplus
When supply and demand are equal the economy is said to be at
equilibrium. At this point (point (P⋆,Q⋆)), the allocation of goods is most
efficient because the amount of goods being supplied is exactly the same
as the amount of goods being demanded. At the equilibrium price
suppliers are selling all the goods that they have produced and
consumers are getting all the goods that they are demanding.
28. Applications in real life and business
in Consumers and Producers Surplus
Coffee is a good example of a product because it is essentially the same across all
producers. However, depending on where it is sold, the price of a cup of coffee can
vary widely. Starbucks can charge more than McDonald’s for a cup of coffee because
coffee drinkers have strong preferences regarding where they buy their coffee drinks
and what they believe is a reasonable price for a cup of coffee. The difference
between the lowest available price for a cup of coffee and the highest price is the
producer surplus.
The sky is dumping freezing rain, it’s 11:30 at night, and you’re standing on a street
corner 15 miles from home. You open your Uber app and see that the trip is going to
cost you roughly Rs.50, as prices are surging 200 percent above normal. But you
summon the car anyways. In fact, you might not have hesitated to go as high as
Rs.100, just to get dry in that comprising moment. Economists would call that Rs.50
difference—between what you pay and what you’re willing to pay—a “consumer
surplus.” They see it as a hard representation of Uber’s value and utility to you, as if
you’ve pocketed Rs.50 in benefits on an otherwise wet and miserable day.
29. Many people appreciate Mercedes automobiles for their styling, mechanical performance and status
appeal. Those who favor owning a Mercedes will pay what they must to have the car of their choice.
The manufacturer of Mercedes automobiles tries to produce the exact number of high-end, mid-price
and low-end autos to meet consumer demand for cars at those price levels. Consumers who can't
afford a new Mercedes at the lowest price level or who want the top of the line but can't pay the price
can always buy their favored Mercedes in the used car market. So, the price of a Mercedes, whether
new or used, is set by the price the buyer will pay relative to the price the seller will charge. This sets
up a situation where buyers and sellers often negotiate final transaction prices, which are based on
the seller's supply of cars in relation to the buyer's desire to buy or demand for the product.
30. CONCLUSION
Whether you aspire to study sociology, psychology, physics, biology or
even economics, math is held in high regard, and you will be called
on solve various maths problems, as part of your work.
Many students and adults never think to use the maths they have learnt, or
are still learning in their everyday lives. In this, they are wrong for many
reasons!
First of all, as we will see, mathematics is present in many aspects of your
daily life, from a trip to the bank, to cooking and even doing DIY.
