o The assignment is copied

Objectives
Objective of this assignment is to make students able to understand the following concepts,
o Recursive Definition of a language
o Regular Expression
o Finite Automata

Question No.1

RECURSIVE DEFINITION
a. Give recursive definition of language defined over alphabet Σ = {a, b}, having all strings STARTING WITH aa OR ENDING WITH bb
b. Give recursive definition of language defined over alphabet Σ = {a, b}, having all strings MULTIPLE OF 2
c. Give recursive definition of language defined over alphabet Σ = {a, b}, having all strings NOT ENDING with aa or bb
d. Give recursive definition of language defined over alphabet Σ = {a, b}, NOT HAVING ab at any place.
e. Give recursive definition of ODD PALINDROME (PALINDROME WITH
ODD STRINGS ONLY) defined over alphabet Σ = {a, b}

Question No.2
REGAULAR EXPRESSIONS
Give Regular Expression for each of the following language defined over alphabet Σ = {a, b}
a. Language having all strings STARTING AND ENDING WITH ab
b. Language of strings NOT having bb OR aa at any place
c. Language of all strings NOT HAVING aab in start
d. Language of all strings NOT HAVING aab in end
e. Language of all strings HAVING count of b’s multiple of 2 [No restriction on count of a]

Question No.3
FINITE AUTOMATA
Give Finite Automata for each of the following language defined over alphabet Σ = {a, b}
a. Language having all strings with alternating a’s and b’s , some example strings are ababab… or bababa…
b. Language having all strings NOT containing aa at any place
c. Language of all strings NOT STARTING with bb
d. Language of all strings STARTING WITH bba
e. Language having all strings NOT having even no of a’s and b’s

Important Note:
While attempting any question always remember the following points:
o Where OR is used in the description of a language it means that expressions on both sides of ‘OR’ are parts of the language.
o Where NOT is used in the description of the language it means that language includes all strings except described in the ‘NOT’ condition, for example language NOT starting with a, means all strings not having a in the start (you have to evaluate yourself what kinds of strings are these).

Assignment Uploading Instructions:
o Upload single word file having solutions for all parts as well as chart images.
o You can crop and compress images in the word file by double clicking on an image and selecting compress all images option to decrease file size before uploading it.

Total Quality Management

The quality of products and services can be measured by their dimensions. Measuring the quality of services and products helps us to understand the concepts of product and service dimensions. Quality is multidimensional so, Product and service quality have a number of dimensions which determine how customer requirements are achieved.

Therefore as being TQM student it is essential for me that I consider the entire dimension that may be important to satisfy my requirements. These are as follows:

Product quality has two dimensions.
Physical dimension measures the tangible product itself and includes such things like length, weight, and temperature etc.
Performance dimension measures how well a product works and includes such things like speed and capacity.

Performance dimensions are more difficult to measure and obtain when compared it to physical dimensions. Like product quality, service quality also has several dimensions.

 Responsiveness refers to the reaction time of the service.
Assurance refers to the level of certainty that a customer has concerning the quality of the service provided.
Tangibles refer to a service's look or feel.
 Empathy being able to understand the needs of the customer as an individual and meet the special requirements of the customer
Reliability refers to the dependability of the service providers and their ability to keep their promises.

Case no. 01
Solution:
I will recommend him/her for considering the following criteria about the quality of cell phone of two different brands available in the market:

 Support of all GSM frequencies by Cell phone providers in operation locally in the entire country
 Steady reception and signal coverage
 Enough Betray capacity, good standby timing and long talk time
 Compatibility of GSM-SIM provided by different cellular companies in the area
 Storage capacity to store call history and text data
 Attractive caller tunes and good multimedia support
 Enough extended memory that should be fixed for audio files or other type of media like pictures, video clips, games etc.
 Good camera and good picture quality if available in the phone package.
 Easy to use.
 Soft keypad.
 Support after sale service.

Case no. 02
Solution:
I will consider the following quality determinates between two bus services;
 Availability of bus stop near home.
 Number of bus stops and distance between these bus stops.
 Service frequency.
 Reliability of bus services that come regularly on schedule
 Availability of shelter and benches at the bus stops.
 Clean less of bus seats, interior and windows
 Cost affordability
 Overcrowding in buses.
