Question# 01:
Scenario
In today’s era of intelligence and mobility where every thing is shifted on mobile like mobile commerce, and mobile computing. Suppose you are working as DBA in a multinational company which works on mobile system and your company decided to change the database structure to embedded database, and as a DBA you suggest your company to used SQLite. State the reasons by which you will convince your company seniors to use SQL Lite?

Solution:
SQLite is file based and embeddable relational database management system. As it is lite and due to its support to relational database management system it is best to use in mobile applications. So, SQLite is very appropriate to construct an embedded database system. It is light database, and it is direct file system engine that uses SQL syntax, also doesn’t require a special database server or anything.
Similarly, SQLite can easily adjust with the requirements of embedded system as it has small core, open source and database is a file which is very easy to apprehend the copy, move and cross platform sharing of database files. Now a days, SQLite use is increasing in embedded systems due to its advantages. SQLite will be more widely used in the embedded field, such as the remote control, intelligent mobile terminal, information appliances control, home medical equipment, mobile devices etc. In a multiplatform architecture SQLite having wide scope.

Question # 02: Write any ten situations in which using SQLite will give best results?

Solution:

Embedded devices or applications Replacement for ad hoc disk files Stand-in for an enterprise database during testing or demos Multi-user applications Data analysis Application file format Server-side database Data transfer format Cache for enterprise data Internal or temporary database Websites File archive/ data container Education and Training Experimental SQL language extensions

1 User is asked to enter name.
2 User is asked to enter number of dependent with range (0-5).
3 User is asked to enter status i.e. (Permanent or Probation).
4 User is asked to enter Salary.
5 User is asked to enter Duration at Job (in years):
o <1
o 1-2
o 2-4
o 4-7
o >7
6 User is asked how much loan is required.

Criteria:
 Loan can be given if and only if a person is on Permanent job for more than 1 years.
 Minimum salary from which a loan can be given is 35,000 per month for a person having no
dependent. Minimum salary requirement increases by 20,000 per dependent.
 If years of services is from 1 to 2 years, then max loan amount can be up to 6 salaries.
 If years of services is from 2 to 4 years, then max loan amount can be up to 8 salaries.
 If years of services is from 4 to 7 years, then max loan amount can be up to 10 salaries.
 If years of services is from 7 to 10 years, then max loan amount can be up to 12 salaries.
 If years of services is more than 10 years, then max loan amount can be up to 24 salaries.
 Add 13% interest on the approved loan amount. This amount will be payable within 8 years’
time i.e. 96 months.
 If the money to lend is more than the lend amount, then calculate the difference and show it
properly.
 For unsuccessful Loan Application: Show Message: “CUSTOMER NAME, your lend
application has not been successful this time”.
 For Successful Loan Application: Show Message: “Congratulations CUSTOMER NAME, your
lend application is successful this time. Your monthly installment will be ______ Amount
Payable for 96 months”.

Q1. Show that the following pairs of regular expressions define the same language over the alphabet

L = {p, q}.

(i) (pq)p and p(qp)
(ii) (p* + q)* and (p + q)*
(iii) (p* + q*)* and (p + q)*
[15 marks = 5*3]

Solution:
(i) (pq)p and p(qp) represents same language.
Both will never generate pp’s and both are starting and ending with p

(ii) (p* +q)* (p+q)*
(p*)+ q p* + q*
p* + q* p* + q*
Both are all strings possible in L = {p,q}

(iii) (p* +q*)* (p+q)*
(p*)* + (q*)*
p* + q*
(p + q)* Language with all strings

Q2. Write a regular expression for the following language over the alphabet L = {x, y} such that it accepts all strings in which the letter y is never tripled. This means that no word contains the substring yyy. [5 marks]

Solution:

The required R.E will be
(˄ + y + yy) (x + xy + xyy)*

Discuss which plant transformation method works best for plant transformation and why?

This natural ability to alter the plant’s genetic makeup was the foundation of plant transformation using Agrobacterium. Currently, Agrobacterium-mediated transformation is the most commonly used method for plant genetic engineering because of relatively high efficiency.

Similarities and differences between “camouflage and Mimicry”.

Camouflage is the ability of animals to blend with the environment using the coloration and patterns while mimicry is the ability of organisms to resemble another organism. This is the main difference between camouflage and mimicry. Both camouflage and mimicry help in the protection or predation.

@zaasmi said in BT604 GDB 1 Solution and Discussion:

What is Fermentation? What are the Key factors relating to improve the economic efficiency of Fermentation process?

The third situation is when the substrate is available in solid form, such as is the case with many organic residues, and it is economically advantageous to use it in this form rather than processing it for use in SLF. There are three main considerations here. First, additional costs are usually incurred in preprocessing the solid material into a form that is suitable for use in a liquid medium. Preprocessing for an SSF process is simpler, as it typically requires only a simple grinding to produce particles of an appropriate size. Second, the capital investment required for SLF bioreactors is higher than that required for SSF bioreactors. Third, large amounts of water need to be added in order to prepare a medium for a traditional SLF process. After the fermentation, the product is recovered from the fermentation broth and the spent broth then needs to be treated before disposal or recycling. Water additions are minimized in SSF and downstream processing is less costly. The ideal situation is when the fermented solid material can be used directly in the application for which it is intended, without the need for prior extraction of the product. One example of this is the production of fermented solids that contain enzymes. After a simple air drying to facilitate storage, these fermented solids can be added directly to an aqueous or organic reaction medium, to catalyze hydrolysis or synthesis reactions, respectively. In fact, SSF is a highly promising technology for application in biorefineries for processing plant biomass; in these biorefineries, many inputs and intermediates are in solid form and can be processed into value-added products using SSF.

write down in detail at least four major problems that teacher face during teaching english???

Disturbed Environment of the Class:

Environment matter most in learning and teaching the English language. Mostly the English teachers faced the environmental problem in teaching the English language.

The disturbing environment of the classroom distracts the teachers and affect the teaching of the English language.

A suitable and comfortable environment is the basic need of teaching the English language.

If the environment is not suitable and comfortable for the teachers then it ruins all the teaching and learning process of the English language.

A positive and comfortable learning environment is very essential for teaching the English language.

Mostly the teachers faced such kind of disturbing environment in teaching the English language.

Limited Teaching Resources:

Not only the English language, Teaching anything mostly depends on the resources.

Mostly the teachers faced this kind of problem, the resources which are essential for delivering the lectures of the English language to the students for effective learning are not provided to them.

It became very difficult for the teachers to teach without the resources essential for the lectures.

The resources include the speakers, mike, projectors, computer system and other kinds of digital devices.

It makes the overall lecture and environment interesting and effective for the students and helps them in learning the English language.

A Large Number of Students in the Classroom:

A large number of students in the classroom produce a lot of disturbance and stress for the teachers because teaching a large number of students the teachers have to do more effort and hardworking.
The problems caused by a large number of students are given below:

Disturbed the teacher by making noises.
Difficult to manage the class students.
Engaging crowded students in learning is very difficult.
The learning resources are not available for all the students.
These are some problems that arise in a crowded class.

Wrong Syllabus to be Teach:

The syllabus is a kind of content that the teachers follow what to teach to the students. Syllabus plays a very important role in teaching the English language and also in other subjects.

Syllabus helps the teachers to prepare the important factors of the course and organized the overall course to teach to the students step by step.

Mostly the teachers faced this problem in teaching the English language. The wrong syllabus is given to them to teach the students the English language.

The teachers teach the wrong syllabus will make negative impressions on the students, and by this, the students cannot learn and speak the English language.

Limited Time for Lecture to Teach:

Time is the most important thing in learning the English language. It takes time for the teachers to observe their students and teach them at their level. The time of the class is very less for the teachers to teach the English language.

This one of the most difficult tasks for the teachers to teach in less time.

This is probably not possible for the teachers to complete the topics of their lectures in less time, which is not enough.

Students Hijack Lessons:

Students hijack the lessons. Mostly the students are not interested in learning the English language. They hijack the lessons and do other kinds of activities and the English learning process defeated.

The English language teachers always count the students because he cannot go further in the course if the students are missing.

Students Disturbed the Class:

Sometimes the students get bored and try to do other activities during the lectures which disturbed the teachers during teaching the English language.

They try to speak to the other students during the lectures which disturbed the teachers a lot.

Some students come late for the lecture. They enter in the class during the lecture it disturbed the teacher.

The disturbance is the biggest problem mostly the teachers faced in teaching the English language. It defeated all the learning process of learning the English language.

Using Other Languages in the Classrooms:

Speaking other languages or speaking in the native language is the most noticeable issue faced by English teachers.

For the students, it’s very easy to speak in their native language or other languages which they can speak easily instead of the English language.

It’s very frustrating for the students trying to speak the language and think the words and sentences to speak which they didn’t know.

It’s very easy for them to communicate in their native language or the language they already have experience with.

This is the most common and big problem faced by the English teachers in teaching the English language to the students in which the English language is not their native language.

Student Depends on a Teacher:

Another noticeable problem faced by the teachers is the students completely depend on the teachers. They didn’t try to learn and speak themselves.
Those students every time look to the teachers for helping them in learning and giving them the correct answers.

They didn’t try to make words and correct sentences in speaking the English language.

By this problem, the students didn’t learn the technical terms and conditions of how using different kinds of tenses and words of the English language in speaking.

Students Bored and not Interested in Learning English Language:

Students getting bored and not interest in learning the English language is also a problem faced by teachers.

Sometimes the students are not interested in learning and attending the lectures of the English language. Then they try to do other activities.

Sometimes They disturbed the teachers by talking to the others and doing other non-sense activities during the lecture.

Difficult to Managed the Class:

In the English learning academies, it can be found that mostly the students in the English classes belong to different backgrounds.

Mostly the students in English learning classes belong to the rural areas. Where there is no scope of learning the English language. it’s very difficult for them to learn the English language.

Mostly they are unable to learn the English language. Some of them have the capabilities of learning the English language.

Then it becomes very difficult for the teachers to manage the class and keep all the class going in the same way.

Suppose that if you’ve ever tried to login to your online bank account and find that not all of your savings are being accounted for, it could be an indication that you’ve been targeted by cyber criminal. Although there are several ways that cyber criminals could have gotten your account data, there’s a fair chance you’ve accidentally come across a phishing website in the past, misinterpreting the login page of your online bank. Enlist all possible security measures to protect your online banking account from cyber criminals.

Respond as if the network has already been breached. Adopting this mindset forces the IT team to prioritize the most business-critical parts of the network and use network segmentation as a strategy. When done correctly, network segmentation, achieved through the creation of network zones, limits the ability for a hacker to move laterally across a compromised network. Network segmentation requires continual updates and configurations, but it can mean the difference between a hacker getting only as far as an employee’s infected computer and helping themselves to the bank’s ATM systems. Implement an enterprise-wide security policy. A well-defined security policy serves as a crucial road map for any bank IT team to maintain a truly adaptive security architecture. It’s what helps the people tasked with protecting the bank’s systems determine the best way for the network to operate with minimal risk. Additionally, the security policy should take into consideration all regulatory and enterprise compliance requirements and how to apply timely patches to maintain compliance. Security policy enforcement. It’s one thing to have a security policy that defines how the IT platform behaves and another to actually validate that it is being enforced across your network. Doing the former but not the latter might allow you to comply with some regulations, but it won’t make your network safer. Organizations must constantly monitor their network for changes to configurations and ensure that these changes are approved and compliant with policy. It’s a collaborative effort across the enterprise—network operations, security operations, and the CIO.
