Welcome to my unofficial notes and reports sharing page
#1.
Let me introduce myself:
I am Dr Jan Pajak. Details of my life, and
my professional accomplishements, are
outlined on a separate web page
about me (Dr Jan Pajak)
available from "Menu "1.
#2.
The goal of this web page:
The goal of this web site is to share my
unofficial lecture notes and research reports, together with a
collection of program samples which accompany these notes and
reports.
Hopefully, viewers can be
inspired by manners in which I solved various matters, while their
knowledge can somehow benefit from my work and teaching experience
encapsulated in this site. The site is also addressed to students
of subjects that I am currently teaching, to my former students
(in case they wish to have a quick reference to a topic, program,
diagram, or material, that I discussed with them during my classes),
to students of similar subjects from other educational institutions
- who may wish to have a look how another lecturer is addressing
a given topic, as well as to my professional colleagues - i.e. other
lecturers and teachers of similar subjects, that may wish to have
a look at "what" and "how" I am teaching. You are welcome to use
these notes, if you feel so, and please do not hesitate to let me
know if you find something in them that is outdated, imperfect, or
simply contains a human error.
A rather unique feature of sample programs
that are attached with my various lecture
notes, is that
they present solutions of almost the
same problems prepared in several different
programming languages. Therefore,
for example a problem of translation of
Arabic numbers into Roman numbers in my
various lecture notes is solved in JavaScript,
Java, C, PP C++, and OO C++ languages.
Similar is with many other programming
problems, e.g leap year verification,
Bubble Sort, calculators, etc.

On one of my field trips to check my
"blowpipe" hunting skills. Although the
use of blowpipes for hunting may appear
to be very primitive, actually it is a very
effective hunting technique. We must
remember that Orang Asli natives from
Malaysia (visible on the edge of this
photograph) tip their miniature darts with
the "curare" poison made from the Ipoh
tree. So animals hit with such darts die
instantly like have been struck by a
lightning. On the other hand, the meat
of animals killed by darts tipped in curare
is still edible (i.e. NOT poisonous).

How my unofficial lecture notes were prepared:
Practically I worked on them during my whole lecturing
career so-far. Especially the examples of programs
contained in these notes are collected over many years,
some originating from the very beginning of my teaching
career. The Tertiary Educational Institutions, in which
I lectured during the period of time when the gathering
of material which gradually eventuated in these notes,
include:
1. The
Technical University of Wroclaw,
Poland (where I was employed as a Polish equivalent to a
reader from English University System)
2. The
Canterbury University,
Christchurch, New Zealand (where I had opportunity to
work as a Post-Doctoral Fellow).
3. The
Southland Polytechnic,
Invercargill, New Zealand (where I had the pleasure to work
as a Senior Tutor in computing).
4. The
Otago University,
Dunedin, New Zealand (where I was a Senior Lecturer in
the Department of Quantitative and Computer Studies,
specialised in Software Engineering).
5. The
Eastern Mediterranean University,
Famagusta, Northern Cyprus (where I was an Associate Professor in
Computer Sciences, with specialisation in Software Engineering).
6. The
University Malaya,
Kuala Lumpur, Malaysia (where
I had a honor to work as an Associate Professor of Engineering).
7. The
University of Malaysia Sarawak,
Kuching, Borneo (where I could contribute my knowledge and experience
working as an Associate Professor of Engineering).
8. The
Aoraki Polytechnic,
Timaru, New Zealand (where I
was employed as a computing tutor).
9. The
Wellington Institute of Technology,
Wellington, New Zealand (which provided me with the opportunity
to utilise my experience and knowledge from the area
of computing by working as an "Academic Staff Member").
10. The
Ajou University,
Suwon,
South Korea,
(which provided me with the opportunity
to utilise my experience and background from the area
of Software Engineering by inviting me for a Visiting
Professorship).
In addition
to this, some information contained in my lecture notes
originates from as far as my employment in industry.
I actually was employed in two large factories, namely in:
11. Computer producing factory Mera-Elwro. (I worked
there as a scientific adviser in the Software Development Department.)
For example, all student projects concerning calculators
originate from this my employment, as one of tasks I helped to
solve over there was the production of a scientific calculator.
12. Bus and trucks producing factory named
Polmo-Jelcz.
(I worked there as a scientific consultant in the Production Technology Department.)
A lot of engineering teaching that I carried out on the Computer-Assisted
Design (CAD), but that are not addressed in these lecture notes,
were based on my work carried out in this bus and truck producing factory.
I would like to take this opportunity, and thank to all
these my countless colleagues and students, who contributed
somehow to the lecture notes that I am using in my teaching,
either by making available their own ideas, or by guiding,
advising, inspiring, commenting, criticising, or just
simply listening. Thank you all! In order to pass further
your willingness to share a knowledge, I am making available
here my lecture notes.
#4.
Programming languages that I lectured in various educational
institutions, and thus that could be addressed in my lecture notes:
Various lecture notes that I prepared
during my professional career, but
which not necessarily are presented
here, elaborated on the following
programming languages:
C for Procedural Programming (PP)
C++ for Procedural Programming (PP), and for Object
Oriented (OO) applications
COBOL for Procedural Programming (PP)
PASCAL for Procedural Programming (PP)
Delphi (in Object Oriented applications)
Java Applets (in web pages design)
JavaScript combined with HTML (as an initial course for scripting
of simple web pages, and also as part of advanced courses
in client-side and server-side scripting).
#5.
Computing subjects that I lectured, thus that impacted the content of my lecture notes:
The list of computer subjects that
I used to teach is quite a long.
It includes, amongst others, the following:
Software Engineering - this is my main specialisation area,
programming in various computer languages listed above in item #4,
fundamentals of computing (including program design
and development, logic charting, numbers systems, operating
systems, etc.),
web pages development (including
programming of web pages, web pages design
methodologies, samples of web pages, etc.)
web pages scripting (including
JavaScript, Java Applets, client-side
scripting, server-side scripting, and more).

My research:
My research have a multidisciplinary character.
For example, apart from research done in computing,
currently I also investigate a device for remote
detection of impending earthquakes and for giving
advanced earthquake warnings. This device is to
raise alarm a long time before an earthquake
is to strike.
Of course, a significant amount of my latest research
related to the area of computer science. In order to
name several topics that I researched from the area
of computer science, these included, amongst others:
(a)
The "all-in-one" idea. This is a new idea
in computing. (I believe that in the formulation
briefly explained and illustrated here - it is
my own idea.) It is based on a very old finding,
that for quantitative calculations which are
needed one time only, a good calculator is
incomparably more useful than a best programming
language. This is why shoppers bring calculators
with them to supermarkets, instead of using
their computers for calculating prices and
spending. I conceived this new idea around
21 May 2005, when in the course of my research,
which at that time I was completing at the
Wellington Institute of Technology,
I attempted to develop a virtual keyboard for an
universal use. I realised then, that it is possible to
design this virtual keyboard in such a manner,
that it obtains a processing power of a sophisticated
programming language, while simultaneously it
still maintains a simplicity of a calculator. I gave the
name "all-in-one" to this new idea of a software tool
for single-use quantitative calculations. Soon afterwards
I completed a first prototype, in which I implemented
practically this new idea. My intention was to develop
a kind of powerful calculator, the processing capability
of which would be equal of these from most sophisticated
programming languages. Unfortunately, just when I managed
to finish a second prototype of this super-powerful calculator,
and intended to subject it to testing and research,
on 22 July 2005 I was made redundant from the IT
position. (There was a rapid drop in IT student
numbers, which NZ experienced at the beginning of 2005.)
In such circumstances I could not carry out the development
of further improved prototypes. Therefore, at the moment
the practical implementation of this "all-in-one" idea still
has a lot to wish for, e.g. regarding the user-friendliness,
ergonomics, types of calculations it is able to carry out,
processing power, etc. However, it already demonstrates
quite well as to what this new computing idea of "all in one"
is about. You can see this second prototype for the
"all in one" idea at the web page listed in "Menu 1".
Of course, the huge potential of this new
idea "all in one" does NOT finish on making
it available to users via present computers.
After all, programming it into computers
must open possibilities to apply it also
in other areas. For example, it can be
implemented relatively easy on the
cellular telephones. After such
an implementation, each cellular phone
would work practically as a keyboard
in the "all in one" idea, linked in
a network with computers of a large
processing power. One does not need
an explanation as to how our life
would get improved, if users of all
cellular phones would rapidly receive
the calculation power equal to that
of the most powerful programming
language and computers, released
with the simplicity of operating
just an ordinary calculator.
(b)
Search engines. I was researching these
in my previous job. (I actually managed to
develop several prototypes of search engines,
and then investigate their properties.
But no engine of my design was implemented
commercially, as yet.)
(c)
Natural languages processing.
(d)
Thermal graph method for investigation of temperature distribution
(this method is a version of finite elements method).
(e)
A language for automatic programming (I actually was an
author of my own programming language called JAP - named
from the Polish "Język Automatycznego Programowania"
(i.e. the "Language of Automatic Programming"), which was
in use for several years at a number of Polish Universities.
