I was born on 13th of March in 1951, exactly 5 years before the great flood catastrophe in the very same small town of Baja and surroundings along the left bank of river Danube southern Hungary, just a few miles away from what is the Serbian border since 1918. Till the age of my 16 we lived - just a stone throw from Red Bridge collapsed by the river ice of the Danube in 1956 on my fifth birthday and named after the red bricks it had been built out of - in dusty downtown between the synagogue and the Serbian church representing the multi ethnic origins and cultural roots of our town. Both were rarely but still used then by the few survived - commemorating to the ancestors who contributed a lot to shape social life, growth and development of the depopulated small town after the Turkish occupation. Baja with a population of 50.ooo located in the heart of wheat and grain area of Bácska at the crossroads of Central Europe's main river and the southern railway crossing over Danube in today's Hungary. In the time of waterways before the railway, the town itself deserved a high commercial reputation and therefore was as large as Pest, the non hilly part of the later Budapest.
Just less than a year after the revolution of 1956 was broken down by rumbling
Russian tanks, from the age of 6 I started the elementary school of local teachers'
training college which school all my children have been going to ever since. My elder
daughter Éva finished in 1990, younger Janka in 2002 and the only boy Bence is still there visiting fifth grade.
Higher classes I continued at/in downtown's
boys' school. Maths became my favorite subject, we counted a lot but I also loved drawing and wanted to be a cartoonist. With continuing at local grammar school
Béla the 3rd, this future disappeared. Remembering the teachers as an
ex-schoolboy, being Primus inter Pares is József Hegedüs, the math tutor. Without his
fruitful but sometimes feared activities, there would have been stick around more dumb and dull chaps in town and some of the/numerous university departments the world over would have been poorer and emptier nowadays.
Our class left Baja's prime educational institute in 1969.
The second half of the sixties in Hungary deserves a few words as well. An ease of firm communist political grip on society and rock, beat and pop music creeping from the West and the sudden availability of new coming technical gadgets of entertainment along with a moderate ease of traveling abroad, and motor bikes and later even cars on sale again like before the war! That was the back water effect of the revolution and the time and consequences of Kennedy's politics of cultural containment. Along with BBC World Service, much jammed short wave stations of Radio Free Europe and Voice of America were much more credited than lying media of local government despite the fact that in their 1956 broadcasts under and after Russian crack down they inspired West's help thus encouraging armed revolutionary resistance of mainly militarily untrained students and workers rousing unrealistic expectations and causing many more loss of lives. Anyhow the sixties were a prickling, mutinous, exciting sparkling time here as well.
After finishing secondary I applied for admission to the Budapest Technical Institute then as known as Technical University of Budapest (BME), I spent the years from 1969 to 1974 there. As a fruitful consequence of meeting my professor Pál Rózsa I was an active member of math's student scientific circle. My mathematical modeling approach was appreciated in several subjects. Along a good deal of beneficial head start, my first encounter with rigorous engineering preciseness - based on heavy load of arithmetical calculations and design drawings regular at technical educational institutions - was not exempt from controversy especially regarding quantity. This conflict have been resolved by showing up of the Computer in my life.
Fortunately first period of computers did not miss me (came not too late to meet me) and so I became a slave of programming in Algol and assembly languages and not that of drudgery on reeling/winding counting machines. Having started nowadays I shouldn't do any hand drawing either. Computer soon take over power, however. Becoming some sort of addicted to, I was not able to live without, and I also made a living from it right away. During the last two years at the university I programmed several rather small scale applications solving real technical problems, and that was the time when - following dr István Zsuffa's needs - I started the development of numerical tasks of reservoir sizing by Moran's model, fruits of which we later published in the USA and still is my highest ranking publication and application in hydrology ever since.
Soon at the university I was taken by smartness and elegancy of recursion and by the importance and effectiveness of numerical methods. Cross iteration of Bernoulli's equation of pressure loss while satisfying Kirhoff's rules proved to be a heavy task with hand run mechanical calculators so I gave up my virginity and turned to the computer to produce my first ever program in Algol 60. I should pass the results to my late educator in water supply, Bozóky Szeszich who also used machines for larger networks. His program was 10-20 page long while I deduct the iteration task into a matrix simmetric in absolute values resulting in a program of a half page in any high level language. At the next - then usually hand made - iteration of stream flow water level - nowadays referred to as one dimensional, a characteristic mentioning of which wasn't necessary back then - those of us interested more were encouraged to use computers and I did. First I did for one stream then - based solely on the recursive definition of the factorial function mentioned in every book - I altered the routine with a single line of recursion and it solved the problem for whole stream network tree as well. The whole simplicity and functionality lied partly in the preparation of the data needed e.g. according to the sequence of routing of the network tree in advance. There were then more computer able people among water related department staff noteworthy the freshly graduated Péter Bakonyi in hydraulics and István Ijjas with high tech irrigation modeling programs with strong dynamic and linear programming of operational research resulting in investment and operational cost cuts with wide spread/range applications in agriculture. Prof V. Nagy and prof Ijjas felt the coming age of computing and just lunched a subject for the some 60 yearly graduating in water related subjects to develop a programming task. Then I had a busy time with lots of consultation with my fellow students.
After graduation I started to work as an application developer, software engineer and system administrator - even if that not existed as a rank or position in that time - practically I was the right hand of dr István Zsuffa - later from a little after the first free elections in 1990 till 1996 head of Department of Water Management, Faculty of Civil Engineering at BME in Budapest. In 1974 we set up the computer center of Baja - the very first one in 100 km distance - dealing mainly with water management applications.
Just after my MSc graduation in civil engineering - when I started to work at local water office in my home town Baja - I entered Bolyai Institute of Mathematics in Szeged the small city of 100ooo on river Tisza and at the university where vitamin C(*) was discovered. Although it coincided with the peak of goulash communism(*) people were not allowed to visit a second higher education institute as a full time student so I started on correspondence course (two days each fortnight) together with roughly 40 ambitious people graduating earlier mainly as engineers, teachers and economists. After the six years of curriculum I was the solely to graduate out of them. Well that was a time when universities were not paid after the number of enrolling and graduating students and although I suspected that the very last student was saved by the teachers I got to know later they were not paid for correspondence classes at all. They were simply strict and I was the only one who survived. In 1969 leaving grammar school - for my free political speech - I was in some ways forced not to go to Szeged University, Party member teachers wanted not risking my becoming a teacher and this deep coded early experience together with the excellence of the lecturers - never met that level at BME except the sole professor Pál Rózsa - kept me endure the hardships of the six years.
Alongside deepening my theoretical knowledge in maths, my restarted mathematical training beneficially and usefully complemented to my prior experience especially regarding numerical methods and theoretical fragments of computational sciences. Curriculum of programming theories proved to be very useful later. I earned my second MSc degree as applied mathematician and - I can't interpret better than - software engineer in 1980.
From 1974 to 1995 I worked for my first work place where we established the first computer center in Baja region and one of the first ones in water management branch of government organizations. By dr Zsuffa's move to Budapest, from 1978 to 1986 I was in charge of the whole IT team.
Baja computer center's impact on the region was impulse. Since the very early stage we followed the „open gates” concept and as a consequence local professionals and those motivated began their acquaintance with information technology at/on our machine(s). In summers lots of local students of far away colleges and universities frequented us for their practical trainings and many graduatings from all over Hungary arrived to prepare their theses in both informatics and civil engineering in my office. Despite the fact that red tape husk/layer protected or covered computers those days, we were famous for our openness. Many later decision makers and researchers of different IT institutions and high tech companies trace back to our former practicing students and thesis preparing graduates. Even nowadays they have often helped us with solution findings for local IT problems. Width the advent and spreading of PCs, time has gone over centralized computer centers and in the very meantime water related government branch has also got slimmer and slimmer in consequent waves of rationalizations. From 1991 Baja computer center ceased to exist any longer, its effect lives on in virtual activity of Baja region however. (see http://www.sugovica.hu/CEU/) Then I worked as a consultant, most actively in preliminary decision support regarding nation wide IT issues in water management.
I learned English on an office course between 1982-1984. Based on my learning experience and knowledge and practice in computer language compiler programming from 1983 to 1987 I set up, organized and lead a team of linguistic university lecturers(*) and computer programmers to develop computer aided language teaching on microcomputers. There were several projects going on within the team and especially fruitful was translation teaching package for Hungarians into English, German and French which won the main award of educational software of the year 1987 issued by John von Neumann Computer Society of Hungary at the then prestigious Micro'87 Computer Show in Budapest. The development was going on and the subsequent royalties contributed the main part of my income for the five forthcoming years. There is wide spread software piracy in Hungary and police and courts not acting efficiently only in cases richest companies of the world involved… So we were forced to leave the market by piracy and there has been no such educational tool in the past decade especially not one costing eleven human years of development.
Far less profitable but from „scientific” point of view, our practical engineering handbook based entirely on Moran's 1956 model's assumptions was more important, however. The book covers my contribution to continuing the applications of earlier small scale and mainly calculator based methods of dr Zsuffa's former encounter with Moran's reservoir model. We finalized our mini computer based earlier Algol and later Fortran programs with Zsuffa's hydrological introduction and lots of data and results of former real world engineering examples accompanied with a short, concise model description and behavior examination we did with the indispensable help of dr. Pál Rózsa, my much admired former math professor.
The example of clearing the model of random demand showed the way of cooperation we did. By having enough good results in modeling reservoirs meeting non random demand, - based entirely on basic combinatorics - dr Zsuffa knocked together a transition matrix of a presumably Markov chain process. This do-it-yourself way of first approach could have been a reliable ground for computation from the point of view of an average engineering user in order to have a quick fix of the problem and to get away with the much needed results. But not in our case. Then there were the advantage of disadvantage. Setting up the model in that way needed vast amount of additional computational power. That's the way how most engineers that time requested - and even today have requested - ever bigger computers for longer runtime. Along with the later spread of computer games that was and still is the motor behind the revolutionary IT innovations. But being behind the iron curtain and not on the favorable part of the COCOM technology „barricade”, we were confined to think twice before one more US dollar was spent on computer hardware in our five year plan economy based on stationing troops of a worker paradise.
We should decrease the amount of computation either by reducing the cases to investigate and somehow deduct one case's derivative residuum from an other case's computed results or by clearing the model and finding a numerically favorable composition of matrices to work with. And like in nursery rhyme „This little pig went to the market this (other) little pig etc…” I transferred the problem to professor Rózsa who in a good deal of work factorized the matrix of complicated structure and made some adjustments thus invented how could have we double the speed or half the variants to be investigated. Having a glance on his factorization I found out the real depth of structure of the model and was ashamed that without this factorization of the combinatorical composition I had not had invented the simplicity of  the duality of matrices representing random input discharges and subsequent random water demands. Thus vital adjustment led to my proposal on  how to decrease the amount of series of eliminations into one single matrix inversion belonging to the maximum capacity that is instead of Σn³, all this solved by a byproduct of an O(n³) modified algorithm of preliminary design of surface reservoirs where lots of different capacities and dam sections should be considered in cases of both random water demand and/or power plants as well.
 Decomposition of the year into months at the end of the month of maximum demand in instationary model fastened the algorithm a lot. The number of possible year end variants decreasing drastically. Chasing the eigenvalues of multiplied monthly transition matrices the number of multiplication/divisions decreased a lot. Thus halving the size of the yearly product matrix and its elimination the necessary number of instructions to be executed is on the 4th to 5th power of size which means 16 to 32 times of speeding up of the algorithm, which - based on Intel cofounder Moore's rule of doubling the speed and capacity of computers each two years period - means log2(16) to log2(32) gaining that particular from four to five years advance or quite reasonably cost cut for the same task.
Investigations of the real behavior of reservoir and the boundary of results deriving from calculations based on subsequent and simultaneous consumptions. I found  the relation between the two models and deduct one from the other, thus proving the two way equivalence of the duality.
What a loss of not having good cooperation between able people of complementary professional areas shows the fate of the virtually same assumptions by a moscowite hydrologist. Savarensky was living probably just a few blocks away from Markov the math genius. Had they encounter on this calculation the model could not bear Moran's name then. But the Georgian boss with moustache somehow managed this favor to Moran in his way.
I really enjoyed the modeling of reservoirs especially the tricky questions of water power plants very much. The trick laid in how to eliminate the disadvantageous effect of separated sequence of input discharges and output water demand of original Moran's model in case of electric power generation or  consider the power production simultaneous with random water input? I made lots of computer programs from the basic modeling to forming algorithms and numerical analysis for different wide ranging areas of not only water management and hydrology - including linguistics - and even as an educator a great lot of fool proof teaching of numerical and mathematical areas, but the modification for simultaneous power production of Moran's model's assumptions and its proving is my deepest contribution to hydrology in general.
The whole business of putting the extended Moran's model into a - by today's standards - poor computer of a very small capacity of 32kBytes was very demanding and required a true understanding of the behavior of the models and resulting algorithms. Finally just for fun and for the sake of presentation as an engineering example for my BSc students, I put the calculation of starting from a given reservoir state into a then available 4kByte Sharp pocket computer with reduced instruction set Basic language in 1983.
In dr Zsuffa coauthor's absence, the finalization of the English version of the book proved to be a never tried non easy task for me and even preparation of the printing happened to be my first desktop publishing experience. A little less than five years after the 1982 invitation for the book by professor Vujica Yevjevich, Water Resources Publication, Colorado, USA published the handbook under the title „Reservoir Sizing by Transition Probabilities” with two diskettes of data and Fortran programs in 1987. Soon after an invitation by WMO Dr. István Zsuffa and I held a seminar in Athens February 1988.
After my English course of 24 weeks in two and a half years and successful test afterwards I was sent to or called for international conferences, first to HYDROCAD in 1986 where I held three lectures/presentation. My connections with universities and development institutes abroad came into built by the new ease of travel between 1989 -1994. I was in connection with computing department at City University of London where I paid a short visit on my own in 1990 and saw the first machine vision laboratory in my life. Back then I was 8 years behind the invention of a simple, low powered shape recognition algorithm which later I developed for ice flow investigation. During the same trip on assignment of Polymed (Zürich, CH) I spent a few days as a software consultant in Baden-Baden, Germany. Then I had already been in acquaintance of MYCIN, the US medical expert system for about five years, while at the company producing medical software in Schwarzwald they had never heard of it. On the other hand medical decision makers in southern Hungary receiving information about it had no previous experience in rule based computing, whereas I had reinvented symbol programming as early as in my first half year of programming as a student at the university when I started writing programs operating on polynomials and have founded several good solutions eg. for getting polynomial approximation for distribution functions. The symbol programming and the gap in my head between using and understanding high level languages and writing machine language programs made me extremely receptive towards system and logical programming and expert systems, my first encounters with PROLOG, CDL, LISP and SMALLTALK dates back as early as 1975-1976.
In autumn 1990 during his guest lecturing at Pisa University professor Rózsa invited me for a short exchange of experience visit. Along my first encounter with world famous leaning tower of Pisa that was my first hands on pass through an Apple Macintosh more suitable for educational purposes than then emerging PCs. My professor had seen our earlier joint envision on math teaching development ideas to come true in Wolfram Research's Mathematica package which I use since the soon after arrival of Windows based implementation in 1992. No need for boring parametrical deduction when programming any longer.
My publications came out in periodical and event connected publications. I held around 10 lectures organized by Hungarian Hydrological Society . As a local computer activist and member of John von Neumann Computer Society of Hungary there were countless lectures, presentations and some sort of short curses for local companies and institutions for interested professionals in town and neighboring villages. As a sort of publication, with my language teaching and other programs I have been out on the market for many years and beside presentations, shows and exhibitions this brought me useful marketing experiences.
My higher education activities covered technical mathematics, modeling of engineering problems and information technology from the very beginning. I performed my first official educational task at Institute of Continuing Engineering Education at BME/BUTE just in the year after graduation 1974-75 teaching computer modeling of water related problems. Later I involved into teaching hydrology and computing at local technical college for water and environment and took part in their research activities for several departments and ensured computing assistance since they had no computer at the college for many years. In joint projects we developed methodology and software for nation wide applications including one of the two significant forecasting methods for river Danube.
Between 1989 and 1993 following my proposal for changes in curriculum regarding maths and computing I was the lecturer of mathematics in the third semester. That was a very exciting task for me and by fulfilling my introductory ideas for the beginning of change, extending basic areas to be taught were successfully elevating the founding of technical subjects up to the level of the first half of twentieth century. Unfortunately with a sudden change in curriculum this development was discontinued and BScs of the XXIst century are educated based on fruits of the XIXth century again. From 1996 to 1999 at the technical faculty of Baja College I held hands-on education in different subjects for the group specialized in informatics. From 2000 my intention is to promote the founding of an agricultural faculty here in Baja.
So what I can advise to young and able people: deal a lot more with founding your PR and take more actively part in what is called today scientific life. On the other hand do not hesitate to build new things, models and follow your initial ideas, even without reading libraryfull of books since in a reciting hungry world really fresh new ideas nearly always had no traces in the past. Reading books sometimes good for not to reinvent and helps what not to do. But sometimes not reading is advantage in order to knock together things not existed before . We in the formerly closed East had thus this "advantage" of not being able to reach international scientific resources. Some, or even most of us were not very much encouraged to buy and read global papers - thus we could in some cases find new ideas more easily but it was sometimes the pure pleasure of producing and inventing and were not able to reap the fruits of even a world wide application. And that was specially true for those who had good teachers raised before tyranny had arrived from where the Sun is rising.
In contrast to memorizing, rebuilding old models and even ideas is very important like constructing triangles. It is the way where one can learn most. Then compare the rebuild in correctness and theoretical and computational efficiency . Anyway conscious human(ity) could not rely sorely on encrypted software packages, this is blocking scientific development. One pay for off the shelf software and by opening disclosure found saying … buyers entitled no responsibility in any aspects… No one knows how interesting it is to build a whole GIS based DTM digital terrain model except those who have built one. And in building even a non efficient but correct package entitle you to be able to select and use from those on the market!
Taking part in civil engineering and linguistic projects is very interesting. (This latter may seem to be at first unusual for a technician but is obvious since we all speak some languages, and are expert of at least one of them…) It is very much inspiring to feel at least a bit of respiration from the air of an age when the world had been not as interdependent as it is today and some polyhistors had still existed…
My civil engineering activities, scientific and educational pursuits stretch on the whole hemisphere from well controlled late East Germany to Algeria, West Germany to Sweden, France at UNESCO to the Netherlands and Portugal. Outside the soon enlarging European Union members and would be members like Slovakia and Croatia it was Mongolia where I spent the longest water power related stay. Most prestigious course I held was in Grecee for WMO. My reservoir and power plant hydrological design software has been used on wide range of problem solving from water power, irrigation, urban water supply, flood control to nature conservation for wetland preservation geographically from Europe to Nigeria, Korea, Algeria and Mongolia.
Especially in its initial part and first years during the decade starting in 1989 I took part in Dutch - Hungarian Joint Project on Revitalization of Old Danube River Branches in Gemenc (Danube-Drava) Nature Reserve Area. Around 1990 over 3 years I served occasionally as an advisor and interpreter on his trip from Regensburg to Black Sea for captain Jacque Cousteau and his staff mostly in Gemenc area and on the long research trip on ADUVIZIG's (Baja Water Office) icebreaker used as a rented research vessel when making film and scientific work on Rhine - Danube, rivers connecting Europe.
I had been involved in networking cameras checking ice on Danube from as early as nearly thirty years ago. The first - black&white analog - camera was set up at the very same position as webcam http://danube.sugovica.hu by ADUVIZIG Baja Water Office in winter 1974/75, when I - as a newcommer - served István Zsuffa, the initiator. Getting information on new networking cameras with built in webserver I investigated technical details and proposed with the reappearance of ice which had been disappearing from Danube at Baja for many years now. The old analog black and white worked on a closed cable network while the new Axis type 2120 Swedish make delivers colorful picture on the internet for everyone interested. Despite technological superiority of today's cameras the old one surpassed the new one in many aspects: using target built analog circuits it produced perspectivically undistorted picture delivering real time ice cover rate. Well, in analog components Nature knows physics better than sophisticated digital equipments. Today's easy to use preprogrammed integrated electronics especially with its overhelming complexity hide information and measuring points which was first glance available for developers in analogue age. Despite the non-transparency of operating systems and integrated components by nowadays - with the ease of remote storage, postprocessing or real time moving detection spiced with shape recognition - ice yield and water discharge estimation will soon be widespread. Hopefully we (will) have some contribution especially in speed and computing efficiency.
This case shows again the importance of rebuilding models since human(ity) could not depend on hidden non transparently programmed unverifiable algorithms. That is why so important the spread of open source software especially when it comes to engineering applications where designer could not bear responsibility when using a program package he/she is unable to trace all aspects of investigating and verifying the whole computation. On the other hand there is a chance - as one of our former colleague's case shows - when someone could use open source public domain for commercial use even pretending himself special expert of the area. We should trade that price for the sake of development and remote education since such non compliant persons will reveal themselfs by their rampant non ability of enhancement in their products.
In the spring of 1996 I extended my formerly part time and supplementary activities within LinguaSoft - developing software in linguistic and technical applications - with hardware merchandise. After a year of getting useful commercial and marketing experience, I took on a position in nearby village of Sükösd commended by a head hunter company for international clients. I managed the regional fulfillment company for the Czech, Hungarian and Slovakian branches of Scandinavian media and telecommunication group - dealing also with electronic commerce - and listed under the name MTGNY (Modern Time Group) on New York's Stock Exchange. Fulfilling marketing and commercial activities in Central Europe of TV Shop Europe AB Malmö Sweden was our task. I was also in charge of optimizing cost and staff from my very beginning, I should readjust the level of efficiency and transparency of Hungarian branch to that of within the group in a euroconform manner. On the base of equal performance and load, 80% of cost and 64% staff cuts were achieved with an increased level of quality and less red tape within the company branch. The three and a half year I spent there proved to be useful for my experience regarding export/import marketing and media issues, I was most impressed by the working method of the - by Hungarian traditional business standard - small and capable staff in an international business organization based on information technology. Based on remote job entry - by sitting to the desk in our virtual office in either Helsinki or Prague or Budapest or Malmö - I could right away work equivalently anywhere. Spread of VPN was still years ahead then. I have been aspiring eversince to spread my experience in the applied IT, QC, telecom and multimedia methods in my local environment in a wider spacial, professional and social context.
From 1999 I have returned to local IT scene. Following my proposal we have started to shape internet presence of town Baja which was given into the hands of two of my former trainees and me. People are given, technology and equipment is at hand. All we need now is intense extension of local content and fresh updates. The civic initiative drew nationwide attention (www.sugovica.hu/CEU/). Besides lively virtual forums and open portal system we - in a small town in Hungary - had given email addresses to our local students and pupils months before it was announced as a goal by French government and PTT post service.
Now as a frequent subject of reorganization before I leave my profession presumably for ever at a very willing to do age let me summarize in listed point the achievements what I think I have contributed as a civil engineer to my profession. The following points could not be listed here in case I hadn't meet my first boss professor Zsuffa and my teachers and colleagues I dare to name them above Most appreciated honorable acknowledgement was in his book review by professor MacMahon from Melbourne university - where from Moran's model originate - citing some of my ideas.
