EEE-2213: Suggestion, Math Syllabus & Lecture Note

1.  Download 3 Dark Lamp Method lecture note from here.

2. Math Syllabus: 
                         Alternator:                   37.1 to 37.10

                                                                  37.34 to 37.38
                     
                         Induction Motor:        34.1 to 34.11
                                                                   34.26 to 34.28

             
3.  Suggestion: Emphasize on questions of Midterm-1 and Midterm-2. Also give special attention to questions I mentioned as important ones in class. Given below are some of the topics you should study for the finals. 
Note: This is not a suggestion for A+, for doing good in exam you'll have to study all the topics in the syllabus.

• Alternator:  Basic Principle, 3-dark lamp method of synchronization,  Zero Power Factor Method or Potier Method
• Induction Motor: Induction Motor Principle, Starting Torque, Condition for Maximum Starting Torque, Effect of Change in Supply Voltage on Starting Torque, Torque under Running Conditions,  Relation between Torque and Slip

Computer Networks: Sample Question for Midterm-2

Try solving the Packet Tracer Activity. You will need Packet Tracer to open the file (check the bottom of the post for download link).

- There will be two windows: a large one (contains the network topology) and a small window.

1. In the first (small) window, enter your name. Email not needed. Then click OK.

CSE-3114/ CSE-3116: Basic Router Configuration via CLI

Today we are going to explore some basic Router configuration commands. We shall use Packet Tracer for this purpose. If you don't have it already, check this post: Computer Networks Introduction. 
Those of you need a little more familiarization with Packet Tracer, check this post.

Steps to follow:

1.  Open Packet Tracer and place a Router in the workspace. Use a 'Generic' model.

Basic LAN Configuration - Practice Topology

Download the Cisco Packet Tracer file (.pkt) and configure the Laptops and Desktops so that they all can communicate with each other.

Download .pkt file

Rules:

1. Use your assigned IP address given in class.
2. Find  (a) Network address,  (b) Broadcast address,  (c) Total number of users,  (d) First user's IP address and  (e) Last user's IP address.
3. After the completion of configuration, use ping command to check connectivity.
4. Save the file and send it to me via Email (nsadat@live.com)   or   Facebook.

How to proceed:

1. Connect the Desktops and Laptops with appropriate cables with the switch. Use FastEthernet ports.

Welcome to students of EEE-2213 (Energy Conversion-2)

Dear students, welcome to my blog. Here you will find the necessary course materials (PDFs, Suggestions, Exam schedules, Results etc.) required for EEE-2213.

Given below is the syllabus of this course. We shall start with the 'Alternators' part.

• Alternators: Construction, Theory of operation. Armature windings, Alternator regulation, Armature Reaction and reactance. Two Reaction Analysis, Transient condition of Alternator. Losses and efficiency, Synchronising and load sharing of alternator.

Special Suggestion for Digital Communication (EEE-3217)

Study the following questions:

1. Detection Error Probability (Last Slide, Last Question)
 Download from here  Communication Slides


2. Example 1.1, 3.3, 3.4 from B. Scalar  (pictures are given below OR you can read from PDF)

1.1

Understanding HDB (High Density Bipolar) Coding

High-Density Bipolar or HDB Coding is used mainly for Bandwidth compression. Using this coding system, we eliminate a large number of consecutive zeros and replace them with certain codes.

Here, HDB3 and HDB4 will be discussed.  Follow each step and you should have no problems understanding the process.

Bit pattern:   10100001100000100000101

Step 1: For HDB3, (3+1)=4 zeros and for HDB4, (4+1)=5 zeros will be replaced with code.
