Question:
“Film is considered by many to be an important art form; films entertain, educate, enlighten and inspire audiences. Suggest any six ways/techniques through which Pakistani Film Industry can revive.”
..............
Solution:

1- Cinema is the backbone of the film industry and the government should provide more facilities for the development of film business.

2- Producers has to produce quality films and cinema owners must respond positively to the producers so that those who have closed their cinemas, reopen and continue their businesses.

3- Welfare funds should be established for the welfare of artists.

4- Prominent showbiz personalities must be involved in the board for the betterment of film industry.Positive Environment and Culture should be provided to Film Industry because it is a need of time.

5- Minister has to play his vital role for revival of film industry on top priority basis which is going to be closed. 

6- We need to exploit talent of our youth as they have great potential but they lack resources, opportunities and encouragement. They can produce quality work if patronized.There are a couple of channels that have not paid their workers’ salaries for months; we should fight against such injustices.

In this way Pakistan film industry can be revive.

With the name of Almighty, dears we’re to discuss the calculus application in the field of our practical life.

First me have to say that “Calculus” is that branch which deals with the integral calculus e.g. calculation area under the curve and the deferential calculus that deals with the motion calculation, and that all are the part of our practical life. Calculus is deeply integrated with the physical science and such as physics and Bio science, so now we can say that it is more important in every aspects of life some of them we’ll here discuss.

It is found in computer science, statistics, and engineering; in economics, business, and medicine. Modern developments such as architecture, aviation, and other technologies all make use of what calculus can offer. Graph visualization are also based on that, we can easily graph the function with the help of it. Finding average of function one example is the path of an airplane. Using calculus you can calculate its average cruising altitude, velocity and acceleration.

So at the end that branch cover a lot of area of our practical life to overcome them we’d have good knowledge of it.

..........................
Another:


"Why do we study calculus,write its at least three applications"

Graded Moderate Discussion will be open on Calculus is Latin for stone, and the ancient Romans used stones for counting and arithmetic. In its most basic sense, calculus is just that a form of counting. After advanced algebra and geometry, it is the next step in higher mathematics, and is used for solving complex problems that regular mathematics cannot complete. 

Calculus is the mathematics of change, of calculating problems that are continually evolving. This is possible by breaking such problems into infinitesimal steps, solving each of those steps, and adding all the results. Rather than doing each step individually, calculus allows these computations to be done simultaneously.

Calculus is useful for solving non-linear equations. For example, say you were looking for the area inside a flat rectangle.

Calculus is deeply integrated in every branch of the physical sciences, such as physics and biology. It is found in computer science, statistics, and engineering; in economics, business, and medicine. Modern developments such as architecture, aviation, and other technologies all make use of what calculus can offer. This page is designed to out line some of the applications of calculus and give you some idea of why calculus is so important and useful. 

Calculus can give us a generalized method of finding the slope of a curve. The slope of a line is fairly elementary, using some basic algebra it can be found. Although we do have standard methods to calculate the area of some shapes, calculus allows us to do much more. A function can represent many things. One example is the path of an airplane. Using calculus you can calculate its average cruising altitude, velocity and acceleration.

Windows Foundation Classes for Java (WFC) provides a framework of Java packages that support components targeted for the Microsoft Windows operating system and the Dynamic HTML object model. WFC is tightly integrated with the Microsoft Visual J++™ development environment and provides a full set of Windows controls written in Java. Building a Java application for Windows is made much easier by this tight integration and the support of features such as IntelliSense, the Forms Designer, the Application Wizard, and the Object Browser. While these Visual J++ features put you well on your way to creating applications, you'll probably want to understand the structure and logic behind the packages and classes that make up WFC.

The purpose of this section is to provide a conceptual framework for the WFC packages and classes and to explain some of the fundamental WFC models. Many of the packages exist as infrastructure for the component model and can be ignored by developers focusing on using the WFC controls. Other packages are most easily accessed from the Visual J++ Forms Designer. When you start exploring the WFC library, you'll want to know which packages and classes are important for your particular application.

.................

First thing about Windows - it is a multi-tasking environment. That means that it can actually run more than one program at one time, giving you higher efficiency. You'll need to process code for each program simultaneously, which is no easy feat. So, the makers of Windows created a system where each program was like a procedure - code was run only when the system requested for it. This meant that they needed to create a whole new system for Windows, containing the API (Application Program Interface). Code was in the form of 'events'. Only when an event occurs will code be run. Now you know why Delphi makes you type code that way!

* WFC Packages provides a high-level overview of the main packages that make up WFC.
* Working with WFC Visual Components describes the controls, forms, and graphical objects in WFC, which include the following subtopics:
o Windows Visual Components
o Dynamic HTML Visual Components
* Handling Events in WFC describes the use of delegates for handling events.
* Localizing Your Application describes the Visual J++ and WFC support and methodology for localizing your project in various languages.
* Using WFC Application Services describes some of the core application features and includes the following subtopics:
o Starting and Quitting an Application
o Handling Application Events
o Accessing System Information
o Performing Clipboard and Drag-and-Drop Operations
* Using Java Threads with WFC describes the threading model for WFC and includes the following subtopics:
o Mixing Java and Win32 Threading Models
o Creating and Exiting a Thread
o Using Thread Storage
o Working with Thread Exceptions

Construct a real world business problem and then apply simple linear regression analysis.
....
Question:-
Suppose that 4 randomly chosen plots were treated with various level of fertilizer in the following yield of corn:-
Fertilizer(kg/Acre) X 100 200 400 500
Production(Bushels/Acre) Y 70 70 80 100

Estimate the Linear Regression of production Y on fertilizer X.

Solution:-
X Y XY X2
100 70 7000 10000
200 70 14000 40000
400 80 32000 160000
500 100 5000 250000
Ã¥ = 1200 Ã¥ = 320 Ã¥ =103000 Ã¥ = 460000 

Byx = n̴XY Р̴X̴Y / n̴X2 - (̴X) 2

Byx = 4(103000)-((1200)(320)) / 4(460000)-(1200) 2 

Byx = 0.07 
ayx = y - Byx X 

= ((Ã¥Y/n) – ((0.07) (Ã¥X/n))

=(320/4) – (0.07)(1200/4)

= 59

y = 59 + 0.07 X is required regression equation.
.................
Following is the detail of investment made and profit gained in a business by an investor for the last 5 years. Calculate simple linear regression y = a + bx
Profit (y) Investment(x)
100 1800
200 1600
300 3000
400 2500
500 1200

Solution:
Let y = a + bx be the simple linear regression where ‘b’ is the slope of regression line and ‘a’ is y-intercept.
y x x2 xy
100 1800 3240000 180000
200 1600 2560000 320000
300 3000 9000000 900000
400 2500 6250000 1000000
500 1200 1440000 600000
sum of y = 1500 sum of x = 10100 sum of x2 = 22490000 sum of xy = 3000000
mean y = sum of y/n = 1500/5 = 300
And
Mean x = sum of x/n = 10100/5 = 2020
As we know that
b = (n . sum of xy - sum of x . sum of y) / n . sum of x2 - (sum of x)(sum of x)
b = [5(3000000)-(10100)(1500)] / [5(22490000)-(10100)(10100)]
b = -0.000146
now
a = mean of y - b . mean of x
a = 300 - (-0.000146)(2020)
a = 300 + 0.296349
a = 300.296
Now regression line y on x is
y = 300.296-0.000146X

Indexing improve our search efficiently but slow down data manipulation operations why? Justify the statement.

Tons of data, complex calculations, busy forms, and even network traffic impact a database’s performance. Your first line of defense against poor performance is a good design that includes appropriate indexes. An index is an underlying structure that determines how Access stores and retrieves data. By default, Access applies an index as follows:

To a primary key field.
To a foreign key if the relationship in question enforces referential integrity.
Access allows only 32 indexes on a single table, which frankly, is more than adequate for most of us. That number includes the indexes that Access sets automatically to primary and foreign key fields (see above). Adding a second index won’t hurt anything, but both will count toward the 32 limit.

You must index non-primary key fields yourself, and that’s where some folks get into trouble: Users fail to apply them or users apply them incorrectly. The following guidelines should help you decide whether a specific index is appropriate:

Don’t index just because you can.
Don’t index tables with little data.
Don’t index just to sort data.
Don’t index just to catch duplicate values during data entry.
Index a field when the data is mostly unique—in other words, there are more different entries than duplicates.
Index a field if you plan to search or sort against the field frequently.
The key to efficient indexing is to remember that an index should improve performance. Don’t apply an index for any other reason than performance. There are better ways to sort and validate data.

On the down side, applying an index to improve performance in one area almost always slows things down in another. For instance, an index might speed up a sort or search, but it will almost always slow down data entry. That’s because Access refers to the index and sorts the index accordingly every time you update the indexed field. Make sure the trade-off is a worthy one. Simply ask yourself whether users will sort and search more than they enter and edit data or vice versa.
....................
When data is manipulated, the indexes have to be updated. This slows down data manipulation.

Answer:-
Search engine indexing collects, parses, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and computer science. An alternate name for the process in the context of search engines designed to find web pages on the Internet is Web indexing. So doing all this operation indexes have to be updated which causes slow manipulation. Because this operation causes the index to be modified and requires additional updating of each index on that table, SQ L has to internally maintain the “pointers” to the inserted rows in the actual data file, each index potentially adds an alternative access path for a query for the optimizer to consider, which increases the compilation time.

“Total Quality Management (MGT 510)”
This is to inform you that Graded Discussion Board (GDB) has been opened according to the following schedule:

Schedule
Opening Date and Time January 26, 2011 At 12:01 A.M. (Mid-Night)
Closing Date and Time January 27, 2011 At 11:59 P.M. (Mid-Night

Note: No extra or bonus/grace period is available for attempting GBD.

Discussion Question

“Total Quality costs reduce the overall cost of the organization. Costs such as prevention, appraisal and failure costs are incurred to improve quality and reduce costs (of loosing customers etc) rather than to increase cost. Discuss with an example in Pakistan’s business sector.” 
.....................
Solution:


In the old paradigm, managers define quality in terms of meeting specifications. Quality is assured by weeding out the “bad” products before they are shipped to customers. Managers make tradeoffs among quality, cost, and scheduling under the assumption that relationships among these outcomes are fixed.

By contrast, in the new paradigm, managers recognize that product quality is only one component of customer value, and managers seek synergies among quality, cost, and schedule, not just tradeoffs. For example, improving quality by reducing variation in outputs reduces defects, reduces costs, and makes performance to schedule more predictable. Further, quality is more broadly defined than just product quality. Quality applies to every aspect of the organization. It must be managed into processes and systems, and not jut inspected into products. Systems’ thinking included to think of all interdependent parts of the system into one whole.

Juran maintains that the Japanese experience leaves little doubt as to the significance of the return on quality training in competitive advantage, reduced failure costs, higher productivity, smaller inventories, and better delivery performance.

Most human error is caused by lack of attention rather than lack of knowledge. Lack of attention is created when we assume that error is inevitable. If we consider this condition carefully and pledge ourselves to make a constant conscious effort to do our jobs right the first time, we will take a giant step toward eliminating the waste of rework, scrap, and repair that increases cost and reduces individual opportunity.

Total quality costs are the sum of the above costs to produce a product or to deliver a service. This represents the difference between the actual cost of a product or service and what the reduced cost would be if there were no possibility of substandard service, failure of products or defects in their manufacture. The measure of revenue saved by producing the right product the first time and every time will actually be the return one gets by implementing the system of quality.

Hence we need to learn that quality system is an investment which ultimately reduces the total cost of production or working as we have to consider every effort of ours financially accountable to make quality a business case.

Quality is a continuous journey and hence not a destination.
