IELTS Practice Test
IELTS stands for International English Language
Testing System It is a test of English language skills
designed for students who want to study in the
medium of English either at university, college or
secondary school.
There are two versions of the test: the Academic
Module and the General Training (GT) Module.
Students wishing to study at postgraduate or
undergraduate level should take the Academic
Module. The General Training Module is designed for
those candidates who plan to undertake training or
secondary school education. The General Training
Module is also used in Australia and New Zealand to
assess the language skills of incoming migrants.
Candidates must decide in advance which of the two
modules they wish to sit as the results are not
interchangeable.
Students sit the Listening, Reading and Writing
papers in that order on one day. The Speaking Test
may be held up to two days later, though normally it
is taken on the same day, after the Writing Test.
A computerised version of the Listening, Reading and
Writing Tests will be available at some IELTS centres
but the paper-based version of IELTS will always be
offered and is the standard format.
Overview of the test
The test is in four parts reflecting the four basic
language skills:
• Listening taken by all candidates
• Reading Academic or General Training
• Writing Academic or General Training
• Speaking taken by all candidates
Results
Performance is rated on a scale of 1-9. Candidates
receive a Test Report Form which shows their overall
performance reported as a single band score as well
as the individual scores they received for each part of
the test.

Practical Troubleshooting Of Electrical Equipment And Control Circuits
Practical Troubleshooting Of Electrical Equipment And
Control Circuits
There is a large gap between the theory of electron flow, magnetic fields and that of troubleshooting
electrical equipment and control circuits in the plant. In this book, we try to avoid or at least minimize
discussions on the theory and instead focus on showing you how to troubleshoot electrical equipment
and control circuits. The book helps to increase your knowledge and skills in improving equipment
productivity whilst reducing maintenance costs. Reading this book will help you identify, prevent and
fix common electrical equipment and control circuits. The focus is ‘outside the box’. The emphasis is
on practical issues that go beyond typical electrical theory and focus on providing those that attend
with the necessary toolbox of skills in solving electrical problems, ranging from control circuits to
motors and variable speed drives.
This book focuses on the main issues of troubleshooting electrical equipment and control circuits of
today to enable you to walk onto your plant or facility to troubleshoot and fix problems as quickly as
possible. This is not an advanced book but one aimed at the fundamentals of troubleshooting systems.
The book is very practical in its approach to troubleshooting and the examples you will be shown are
applicable to any facility.
We would hope that you will gain the following knowledge from this book:
• Diagnose electrical problems ‘right-first-time’
• Minimize the expensive trial and error troubleshooting approach
• Reduce unexpected downtime on electrical motors and other equipment
• Improve plant safety
• Learn specific techniques to troubleshoot equipment and control circuits
• Analyze equipment problems
• Determine causes of equipment failure
• Troubleshoot electrical equipment and control circuits.
Typical people who will find this book useful include:
• Plant Electricians
• Mechanical Engineers
• Production Operators and Supervisors
• Utilities Maintenance Personnel
• Plant Engineers.

Handbook of IPv4 to IPv6 Transition: Methodologies for Institutional and Corpora
In 2005, the U.S. Government Accountability Office recommended that all agencies begin planning a coherent transition to IPv6. IPv6 will solve the problem of limited IP addresses and improve internetworking capabilities. This promising protocol is gaining momentum and it is only a matter of time before the transition will have to occur globally. The problem is that during the three-to-six year transition period, IPv6 and its predecessor, IPv4, will have to successfully coexist in order to ensure service continuity.
Not only federal agencies, but corporations and institutions must start planning the transition to IPv6 now to maintain the operation, security, and interoperability of their networks.
The implementation of IPv6 is essential to the continued growth of the internet and the development of new applications. The Handbook of IPv4 to IPv6 Transition Methodologies provides a wealth of best practices and procedures that will help corporations plan and implement a smooth transition to IPv6.
