Project Implementation assignment #2

Case Study – CTI

Example: Suppose that we are going to carry out a minor redesign of a portable telephone set and its associate packaging at Carrier Telephone Industries (Pvt) Ltd. Islamabad. We intend to test market this redesigned product and then revise it in the light of the test market results, finally presenting the results to the board of the company. The key question is:

How long will it take to complete this project?
Draw the Network diagram?
Calculate the minimum overall project completion time?

Solution: After much thought we have identified the following list of separate activities together with their associated completion times.

Number completion time (days)

1. Redesign product 6

2. Redesign packaging 2

3. Order and receive components for redesigned product 3

4. Order and receive material for redesigned packaging 2

5. Assemble product 4

6. Make up packaging 1

7. Package redesigned product 1

8. Test market redesigned product 6

9. Revise redesigned product 3

10. Revise redesigned packaging 1

11. Present results to the board of directors. 1____

Total Completion Time 30 days

Aside from the list of activities just mentioned, we must also prepare a list precedence relationships indicating activities which because of the logic of the situation, must be finished before other activities can start, i.e. in the list on the last page activity number 1 must be finished before activity number 3 can start. It is important to note that, we try to keep this list to a minimum by specifying only immediate relationship, i-e relationships involving activities that “occur near to each other in time”. Now we come up with the following list of immediate precedence relationship:

Activity Number Activity Number

1 Must be finished before 3 can start

2 4

3 5

4 6

5, 6 7

7 8

8 9

8 10

9, 10 11

Hence 24 days Is the minimum time needed to complete all the activities and hence is the minimum overall project completion time. Thus six days will be saved.

SAMSUNG A800 SECRET CODES

The universal unlock code is 2767637# do this with out your sim in

By default, the firmware (software) for x600 only receives java
apps and other applications like stuff by serial port.
but even for it, you have to enable the serial port, which also
causes
the closing of all other ports, even the IrDA too :-( ..

well, guess what, i have very good news for you,
do you know, you can increase the sound level,
the sound level for tones, speaker fone, etc,
can be increase even then if it is at max (level 4)

you still can do it,
just follows the instructions!

** HERE WE GO

Enter the following code:

#89998378#
(You'll be shown menu, then ...)

then go to:

"H/W test"

then go to:

"Audio Settings"

then go to:

"Melody Gain"

There will you see a number.
there are five (5) Melody Levels" of it.
(and currently, you are at level 1 and after
pressing the "save" button, you will move to
level 2 and so on .........................)

you have to change the values of all the levels.
and as the resultant, it will give increase the
melody sound!, your tones will more louder,
even more louder then the max. ringing volume.

the level wise numbers are: (as its my setting :-) )

Melody Level 1: 13

Melody Level 2: 17

Melody Level 3: 18

Melody Level 4: 25

Melody Level 5: 31

you even can make your own combinations of level wise
sounding numbers that can change the sound level!.

if your combination cause more louder sound level,
then mine,
then do share it with the group! ... :-)
meanwhile, try my figured-out combination!

CAUTION

if anything goes wrong,
then you can apply the master reset code,
that will NOT delete anything, ANYTHING from your
cell fone, but set each and eveything to its
default/standard setting ...
(likes, factory settings :-) )

the master reset code is:

#*7728#

#########################################
I take no responsibility of these codes are working or not,
or its effects on your cell fone
but i have tried these codes on my cell fone.
and i bet, nothing goes wrong,
but even then of my words, be carefull!,
#########################################

The code: #89998378#
as i regarded it a informative code,
will tell you each and everything about your cell fone.
and in the "H/W test",
there are lot of other Audio settings,
each of them having five (5) levels,
you can change the combination, but before doing anything,
do write the defult number sequence to some place so that
you'll be then able to invert it again! .. :-) ...

Then replace 6 by 0, it'll show 12 but it's OK
Press back until main screen
Then press key volume to minimum and let's try !!! no more sound

Learning

Q: Write a note on the theories of learning.

Definition of Learning:

Learning is a process we do all the time. We observe our sorroundings, experience the situation and gain knowledge and that knowledge change our behavior. Change in behavior indicate that learning has taken place. A generally accepted definition of learning is “ Learning is any relatively permanent change in behavior that occur as a result of experience”.

Theories of Learning:

Following are the two theories to explain the process of learning.

1) Classical conditioning.

2) Social learning.

1) Classical conditioning:

A conditioned response is learned by associating a conditioned stimulus (neutral) with an unconditioned stimulus (compelling), whereby the neutral stimulus becomes a conditioned response. It is a type of conditioning in which an individual responds to some stimulus that would not ordinarily produce such a response.

Experiment:

Classical conditioning grew out of experiments to teach dogs to salivate in response to the ringing of a bell, conducted in the early 1900s by Russian physiologist Ivan Pavlov. A simple surgical procedure allowed pavlov to measure accurately the amount of saliva secreted by a dog. When Pavlov presented the dog with a piece of meat, the dog displayed a noticeable increase in salivation. When Pavlov withheld the presentation of meat and merely rang a bell, the dog did not salivate. Then Pavlov proceeded to link the meat and the ringing of the bell. After repeatedly hearing the bell before getting food, the dog began salivate as soon as the bell rang. After a while, the dog would salivate merely at the sound of the bell, even if no food was offered. In this experiment we can review the key concepts of classical conditioning.

The meat was an unconditioned stimulus, it invariably caused the dog to react in a speacific way. The reaction that took place whenever the uncoditioned stimulus occurred was called the inconditioed response. The bell was an artificial stimulus, or what we call the conditioned stimulus. Although it was originally neutral, after the bell was paired with the meat, it eventually produced a response when presented alone.

2) Social Learning:

The learning that occurs by observation and direct experience is called social learning. Social learning theory is an extension of operant conditioning. The influence of the model is central to the social learning theory.

Process in Social Learning:

1) Attentional Processes:

People learn from a model only when they recognize and pay attention to its critical features. We tend to be most influenced by models that are attractive, repeatedly available, important to us, or similar to us in our estimation.

2) Retention Processes:

A model’s influence will depend on how well the individual remembers the model’s action after model is no longer readily available.

3) Motor Reproduction Processes:

After a person has seen a new behavior by observing the model, the watching must be converted to doing. This process then demonstrates that the individual can perform the modeled activities.

4) Reinforcement Processes:

Individual will be motivated to exhibit the modeled behavior if positive incentives or rewards are provided. Behavior that are positively reinforced will given more attention, learned better, and performed more often
