SpringerBriefs in Applied Sciences
and Technology
SpringerBriefs present concise summaries of cutting-edge research and practical
applications across a wide spectrum of fields. Featuring compact volumes of 50 to
125 pages, the series covers a range of content from professional to academic.
Typical publications can be:
. A timely report of state-of-the art methods
. An introduction to or a manual for the application of mathematical or computer
techniques
. A bridge between new research results, as published in journal articles
. A snapshot of a hot or emerging topic
. An in-depth case study
. A presentation of core concepts that students must understand in order to make
independent contributions
SpringerBriefs are characterized by fast, global electronic dissemination, standard
publishing contracts, standardized manuscript preparation and formatting guidelines,
and expedited production schedules.
On the one hand, SpringerBriefs in Applied Sciences and Technology are
devoted to the publication of fundamentals and applications within the different
classical engineering disciplines as well as in interdisciplinary fields that recently
emerged between these areas. On the other hand, as the boundary separating funda-
mental research and applied technology is more and more dissolving, this series
is particularly open to trans-disciplinary topics between fundamental science and
engineering.

Preface and Acknowledgements
This book, a maiden edition, is packed with several years of classroom teaching
and research activities of a seasoned tutor of research techniques in engineering. Its
goals are to assist in dealing with the required generic and soft skills to successfully
conduct research and technology development by undergraduate and graduate engi-
neering students or for a successful research and technology development career in
academia and industry. Research in the engineering field requires a set of specific
skills, distinctively unalike in approach to other scientific communities. The archival
literature or bibliographic databases that might be beneficial for literature searching
and review differ, and the challenge of choosing to publish the research findings as
a patent, journal or conference paper is a dilemma most research technique books,
typically do not consider.
Notwithstanding the engineering discipline or research topic, the tasks ahead of
any researcher undertaking engineering research include the necessity to choose a
researchable topic; state the problem statement; identify the aim and objectives of
the study; plan and design an appropriate methodology; collect, collate, and analyse
findings; and write a well-written report. Though engineering research projects
often demand hi-tech, sophisticated techniques, and typically, computing and statis-
tical knowledge. It is entirely possible to carry out a meaningful research project
without the expertise in computing and statistical knowledge. Moreover, conducting
a research project is best learnt by doing it; however, numerous efforts and goodwill
might be wasted and dissipated due to lack of adequate planning and design of the
project.
Engineering research, typically conducted in the academia or industries, are
industry-driven and their deliverables are, thus bound by timelines and driven
by customers’ requirements, in particular, for research carried out in research or
industry laboratories. Also, engineering research demands some cautious ways and
manners of response to reviewers’ criticisms of submitted conference or journal
paper manuscripts, or criticisms of submitted project reports by project supervisors,
examiners, or lab managers in academia or industry. So, regarding these, tips are
provided.

viii PrefaceandAcknowledgements
In this book, the technique of concentrating on the research project by stating the
research problem and phrasing research questions, the art of using libraries, creating
an effective literature search strategy and review, developing a research plan, and
writing a project report and its presentations, coupled with specialised or focused
aspects, associated with a stream of engineering, such as the use of commercial
software for modelling and simulations, and citation management, were all discussed.
I have been encouraged throughout the writing of the book chapters by the interest
of former and present undergraduate and graduate students, colleagues, friends, and
associates. I am, in particular, grateful to Mr. Abdul Wahab Lawal, an educationist,
poet and editor who proofread and commented on the drafts of all the chapters, and
other colleagues who have encouraged and provided insights during the writing and
production processes.

About This Book
This book entitled Research Techniques: Qualitative, Quantitative and Mixed
Methods Approaches for Engineers provides a hands-on guide towards conducting
state-of-the-art engineering research. It gives pragmatic, step-by-step instructions
that covered every stage in engineering research, from choosing a topic through to
the presentation of research outcomes. The topics covered include the introduction
and basic concepts of engineering research; research problem and questions; use of
libraries, literature search and review; developing a research plan; and project report
writing and presentations. This book, written in particular for engineers across all
engineering disciplines, is ideal for undergraduate and graduate students; first-time
or beginner researchers and academics intending to launch their research studies and
careers; and would be of service as a reference resource to researchers, and those in
the academia and industry.
The unique features of this book are its provision of unique engineering perspec-
tives; discussion of research planning and implementation tools for engineering
researchers, provision of pragmatic, step-by-step instructions for conducting engi-
neering research; presentation of generic and soft skills required for impact; and
offer of outstanding service as a reference resource to researchers and those in the
academia and industry.
