Dina ruler

Dina  •  Annual report  2001

Introduction

The year 2001 was the second in a three-year working period with a reduced budget and focus on the following core activities: As an extraordinary event, Dina organised a round table discussion on teaching informatics to biologists. The discussion took place on Sep. 24 and had approx. 35 participants; it is briefly reviewed elsewhere in this report.

By the end of 2001, the funding from the PIFT programme under the Danish Research Councils, which began in 1991, had finally expired. Most of the programme was reported on in the printed publication "Dina 1991 - 1999" and in the Dina Report "Dina 1991 - 1999: Publications". In 2001 the only major Dina activities financed by PIFT were the last year of two PhD projects in Aalborg/Foulum.

Today actual project activities in Dina, as a rule, take place outside the field of Dina's own budget and responsibility. However, from time to time the network will coordinate applications for the funding of new projects - an activity which will typically involve the management and the appropriate IT coordinators.

Below follows the detailed report, ending with the plans for 2002.

The board

Two board meetings took place on April 18, 2001 at FSL, Hørsholm and on Dec. 18, 2001 at AAU, Aalborg. A third meeting via VideoLink, scheduled for Sept. 14, 2001 and with the unique purposeoof discussing a draft for an application from Dina to FUR, the Danish National Programme for Research Schools, was called off when it turned out that all members of the board were in favour of the proposed application which was therefore sustained.

Important items on the agenda of the April meeting included the election of a chairman and vice chairman of the board; revision of the priority research areas; plans for a round table discussion on biology and informatics; and evaluation of the annual meeting in March 2001. Leif Herløv was elected as the new chairman and Søren Aggergaard Mikkelsen as the new vice chairman; the two thus exchanged roles. Generally the board approved the continuation of the priority areas; in particular that the activity in the area "Information Technology and Agricultural Engineering" is gradually being transferred to the new network DaNet. The planned round table discussion and the annual meeting practice were also approved.

At the December meeting, the board discussed the above-mentioned priority research area and the cooperation with DaNet; representatives of DaNet were invited to join the meeting. Besides this, the board evaluated the activities of 2001 and adopted the plans and budget for 2002.

The management

The management still consists of Mogens Flensted-Jensen (head) and Iver Thysen (deputy head); Academic secretary: Poul Einer Hansen; Secretary: Carina Jensen; Webmaster: Thomas Iversen.

The main contribution of the management group in 2001 has been to support the core activities, in particular: the annual meeting; the Dina workshops; and the research school. Quite an effort also went into organising the round table discussion on September 24 on Informatics for biologists.

Finally DinaNews 2 was edited in January, the annual report for 2000 was ready in April, and the website has been maintained regularly.

The Network Committee

The Dina Network Committee consists of representatives from Dina member institutions and the management. The Network Committee meets 2-4 times per year; the IT coordinators and the research school experts are invited to the meetings.

In 2001 the Network Committee met twice: on March 11 via VideoLink, and on August 27 at KVL. The main topic for both meetings was a discussion with the IT coordinators about the work done within the Priority Research Areas. Minor changes of the foci and titles of Priority Research Areas were recommended. The future status of the Priority Research Area "Information Technology and Agricultural Engineering" and Dina's cooperation with DaNet remain to be solved in 2002.

The Network Committee also discussed Dina Research School and the Annual Meeting. Besides this, many practical issues were solved in an informal way within or outside the agenda of the Network Committee meetings.

The Network Committee is a co-ordinating body: it assists the Dina management in preparing material, data and recommendations for the board; it carries out the general planning of annual meetings and workshops; and it coordinates large project applications, typically by appointing an ad hoc committee.

The Network Committee is of major significance to Dina=s work. In an informal way, the committee maintains the solidarity and the cooperation that was established in the period where Dina was developed on the basis of shared project grants.

The Annual Meeting

As in 2000, Dina organised its annual meeting in cooperation with DSIJ, Danish Society for Informatics in Agriculture, but this year a third partner entered the group of organisers, viz. DaNet, Danish Agricultural Network in Engineering and Technology. The organisers wanted to add a substantial contribution to the ongoing discussion of agricultural engineering: how will this discipline at university level be able to cope with the trend towards ever larger, more complicated and more expensive machinery? And: where is the borderline to be drawn between traditional technology and IT, in a specifically agricultural context?

Scheduled to last for two half days, the annual meeting took place on March 1-2 at the Scanticon Center in Rebild, North Jutland. Among a total of 96 participants, 4 came from Norway, 3 from Sweden, 2 from Finland and 2 from Iceland.

The aim of the meeting, which was held in Danish, was to look at the situation within information and technology intensive agriculture: at I & T for people, I & T for animals, I & T in machinery, and how they interact through datanets.

On the first day, three invited speakers (Thomas Nejsum Madsen, Danske Slagterier, Prof. Simon Blackmore, KVL and Prof. Tomas Nordfjell, FSL) described the state of the art in data collection, monitoring, and automated control and management, be it in the forest, the field or the stall. Based on tangible experience, the lectures pinpointed the actual situation of I & T in agriculture, in Denmark and internationally. The following parallel sessions included: (1) Field and forest: data collection and monitoring, (2) Field and forest: automated machinery, (3) Management of livestock. In the evening, Susanne Sander, Landbo Nord gave a good old-fashioned lecture on 'social perspectives' : where does the fact that life in the countryside has, over a few decades, changed into something that looks like computer controlled big industry, leave people working in agriculture?

On the second day there were lectures on technological perspectives. The Head of Dept. Svend Holme Sørensen, Siemens, spoke about modern datanets; Prof. Mogens Blanke, DTU, about the security and autonomy of technical systems; and Assoc. Prof. Kristian G. Olesen, AAU, about advanced electronic agents and services. The common concluding debate was initiated by Erik Steen Kristensen, Research Center for Ecological Agriculture; he addressed the question of how new technology is used on the conditions of nature. The three parallel debates from the first day were combined; and finally Gitte Meyer, KVL's Center for Bioethics and Risk Evaluation, gave a talk on how to achieve animal welfare through technology.

The meeting was presided over by Anders P. Ravn, Dina Aalborg. Ellen Juel Christensen, Dina FSL, and Erik Jørgensen, Dina DJF represented Dina in the organising committee which deserves much credit for an arrangement that was well planned and implemented.

The Dina Research School

Head: Anders Ringgaard Kristensen. Experts attached to the school: Per Grove Thomsen, Peter Sestoft and Henrik Stryhn (until August 2001).

During 2001, the research school organised the following events:

Workshop on Optimisation, Koldkærgård Landboskole, 26-27 April. Due to a low number of applicants the workshop was cancelled.

Nordic summer school: Geographical Information and Spatial Analysis in Agriculture, ås Campus, Norway, 18-28 June.

Background: The usage of computer based Geographical Information Systems (GIS) has been rapidly increasing, also within agriculture. The possibilities of getting hold of data has been vastly improved during the last decade, through remote sensing by satellites, by improved air surveillance methods, by seismic measurements and by ground measurements with the aid of GPS-technology, to mention just a few. However, there are considerable challenges in organising, storing and processing all this data such that reliable and acceptable results are achieved with a reasonable consumption of computing resources. Available models and methods approach this problem in different ways, and based on different assumptions. Recently there has been an increased interest in GIS that can handle the time dimension in addition to the traditional spatial dimension.

Goal of the summer school: Participants should understand the possibilities and limitations in using GIS as a tool for scientific research within agriculture, forestry, area planning and environmental issues; they should achieve a deeper knowledge of the models and methods used in the analysis of geographical data and the fundamental assumptions behind them; and they should acquire a better basis for planning scientific investigations, choosing between different methods and judging the results with regard to credibility and accuracy.

Main themes: The participants were invited to join the ScanGIS'2001 conference, which took place during the course. The summer school had 25 participants of which 7 were Danish PhD students. The Norwegian contact person of the research school, Gerhard Skagestein, was responsible for the scientific contents together with Geir-Harald Strand. The international guest lecturer was Professor Margaret A. Oliver from England. Further information, including the programme and evaluation by participants, may be found at the web address http://www.dina.dk/phd/s/s4/.

Workshop on Visualisation and Data Mining, Tune Landboskole, December 6-7. An essential part of scientific work nowadays consists of acquiring insight from either a vast amount of data collected from experiments, or computations involving long sequences of numbers. The numbers will often be available in various data-formats and specially designed tools are necessary in order to extract information from the numbers.

The workshop introduced some of the popular techniques that are available to the scientists for obtaining a high level of insight from very large amounts of data. Visualisation is part of everyday life: we look at weather maps on TV and are entertained by the graphics in computer games - examples are plenty. In science, visualisation is however relatively new. New technology has made it everyday life for scientists to present their results in pictures and graphs. Pictures bring insight into the nature of processes, and the changes of states in a dynamical system may be animated to identify new relationships between system components; the old-fashioned tables of endless numbers are outdated in today's scientific world. - The workshop gave a state-of-the-art introduction to Visualisation and Data Mining, incorporating a brief hands-on experience with modern tools from the industry.

The workshop had 29 participants including 9 PhD students from Norway, Sweden and Finland. Per Grove Thomsen, together with Per Bruun Brockhoff, were responsible for the scientific content of the workshop. Further information, including the programme, may be found at the web address http://www.dina.dk/phd/w/w9/.

The Nordic research training network, NINA. The Dina Research School is coordinator of a Nordic network (NINA, Nordic Informatics Network in the Agricultural Sciences) financed by NorFA. A network meeting was held at Hotel Scanticon Comwell, Rebild Bakker, 28 Feb. - 1 March, where the future summer schools of the network were discussed together with other activities. Further information, including the programme, may be found at the web address http://www.dina.dk/phd/nina/m3/. The annual summer school is the main activity of the network, but in addition funds are available for participation in workshops, symposia and courses in the other countries. In 2001 trips to the following events have been paid for by the network:

Priority research areas

Spatial Statistics in Agriculture
IT Coordinators: Rasmus Waagepetersen and Morten Larsen.
The main effort in 2001 was the organisation of a Nordic workshop on spatial statistics in agriculture and forestry. The workshop took place at KVL on 1 Nov. 2001 and had participants from Sweden, Finland and Denmark. It covered a broad range of topics within the area of spatial statistics and a wide selection of applications in agriculture and forestry, including yield measurement, precision field management and forest modelling, as well as more theoretical or research oriented contributions. There was very good in-depth discussion, and the broad theme led to the participation of some groups we had not previously seen at our workshops.

For more details, including the programme, list of participants and abstracts, see the website for the priority area: http://www.dina.kvl.dk/~ml/dina/itcoord/ under "Previous events".

Information Technology and Agricultural Engineering
IT Coordinator: Anders P. Ravn.
During 2001, DaNet (Danish Agricultural Network in Engineering and Technology), see http://www.agrsci.dk/jbt/danet, has expanded and now includes partners from LR and several industries as listed on the home page. DaNet is still a very informal organisation and, in particular, its affiliation with Dina has required some discussion. Currently, it looks like DaNet has to maintain its existence as an independent network, because hard core engineering and the machine industry has only marginal interest in most Dina activities. However, it is the intention to work closely together, for instance with the annual meeting, in matters of research schools and research policy. A key activity for DaNet in 2001 was to organize broad meetings around the themes of the Digital Farm, the Digital Pigstall, and the Digital Cowhouse. The meetings took place in February and March and resulted in continued activity around project proposals up to the November call for project proposals. Now that the projects have been evaluated, DaNet may try to coordinate what is left, in order for the research action to give a general lift to the area.

Internet-based Advisory Systems in Agriculture IT Coordinators: Jens Peter Hansen and Ellen Juel Nielsen.
The 2001 contribution focused on a seminar with the theme "How can the Internet supplement - maybe entirely replace - traditional advisory service in agriculture?" The seminar took place on 30 Aug. 2001 at The Danish Agricultural Advisory Centre, Skejby and had 60 participants. The purpose of the seminar was to exchange ideas about fruitful ways to benefit from the use of the Internet in relation to advisory services. Presentations focused on how to exploit the Internet seen from a business and organisational point of view. There were presentations from a private company, from local advisory centres and from The Danish Agricultural Advisory Centre. The presentations and the following discussion clearly indicated that the use of the Internet is an important competitive parameter in attracting customers and servicing these. A more technical presentation showed how tasks in relation to Internet applications can be shared between advisor and farmer; how video can support on-line advising; how to utilise the Internet to gather data for decentralised interactive bench marking; and how organisations can improve their knowledge sharing via the Internet.

Most of the presentations can be seen at http://www.lr.dk/dina/internetraadgivning/html/seminar2001.html

Model-based Decision Support Systems in Agriculture IT Coordinators: Erik Jørgensen, Alllan Leck Jensen and Nils Toft.
A major activity in 2001 was to organise one of the sessions at the Dina/DSIJ/DaNet annual meeting. The session focused on two points-of-view: 1) Are existing technology and methodology used adequately? - and 2) Can current technology and methodology fulfil the expectation of the end-users? Participants covered a wide range of expertise. The session started with stimulating introductions from various speakers, and the resulting debate touched on a wide range of the essential items in adapting technology within agriculture.

As a follow-up to this discussion, a further workshop concerning sequential monitoring systems was planned to be held in late autumn, but it became necessary to postpone it to the spring of 2002. At the EUNITA meeting in Montpellier, a session concerning Sequential Decisions was organised, and it is expected to be followed up by a symposium in Toulouse in autumn 2002, with a French, Spanish and Danish organising committee.

Activities also comprised project applications in areas such as expert systems concerning tail biting, vision monitoring of weight, and other decision support applications.

As already mentioned, the workshop on sequential monitoring will be held in March 2002.

Bioinformatics and Quantitative Genetics
IT Coordinators: Mogens Sandø Lund, Gunter Backes and Henrik Christensen.
The workshop "Biodiversity investigated by phylogenetic methods" took place on 16 Nov. 2001 at Research Center Risø, and it was attended by 17 Danish scientists. Seven presentations covered the phylogenetic investigation of bacteria and higher plants mainly based on molecular traits such as DNA sequences, transposable elements, DNA-fingerprints and the degree of DNA-hybridisation, but chemical characters were also considered.

Projects and activity reports

This section gives an account of what has happened to a number of specific projects and Dina members during the year. The order of the reports is random and we have not attempted to standardise their form, or their size.

Combination of remote sensing data for invention and health surveillance of a forest
Project workers: Mats Rudemo (contractually liable) and Morten Larsen.
This three-year project is funded by the Danish research councils within the program "ESA Følgeforskning" (ESA derived research) and is carried out in cooperation with FSL. The purpose is to develop tools of analysis for combining panchromatic high resolution aerial photographs and multispectral, 1 to 4 metre resolution satellite images, aiming at inventory and monitoring of a mixed forest. Two FSL sample plots in Jutland which had been selected for the project were photographed from the air in the summer of 2001 and some initial rectification of this data has been done. Ikonos imagery from approximately the same period was supposed to have been acquired, but Space Imaging Inc. has been unable to supply the requested scenes, so the acquisition of actual satellite images has been postponed until May 2002. Meanwhile the colour infrared images from the photo campaign will be used to simulate satellite images. Ground truth data from the two plots has been supplied from FSL and has been validated and corrected at KVL.

Continued development of the Daisy model
Project workers: Søren Hansen and Per Abrahamsen.
The Daisy code has been ported to the Linux platform and provided with additional "default values". The model has been extended with new logging facilities, making possible the logging of water and nitrogen balances. The model has also been extended to simulate field carbon balances and this new development has been validated in connection with the project "Remote Sensing Based Crop Simulation and Soil-Vegetation-Atmosphere-Transport Modelling". - The main plant growth model has been extended at the following points: Activity report from Søren Hansen
Charlotte Tofteng's PhD project, on the effect of macropores on the transportation processes in the root zone, was abandoned in 2000. However, at that time it was agreed that some of the obtained results should be published in an international journal. The result of this effort is the article Tofteng et al. (2002).

Activity report from Jesper Møller
Ole Fredslund Christensen's PhD thesis on geostatistics and Markov chain Monte Carlo methods was submitted in September 2001 and defended in December 2001. The thesis consists of five papers and a manual for software implementation. One article (co-authored by Peter Diggle and Paulo Riberio Jr., Lancaster University) concerns the analysis of spatial data using the transformed Gaussian model, where the methods are used to analyse rainy weather. The four remaining articles (two co-authored by Rasmus Waagepetersen and Jesper Møller; one by Rasmus Waagepetersen; and one written by OFC alone) deal with generalised linear mixed models for the analysis of spatial data. Methods for Bayesian inference and maximum likelihood using Markov chain Monte Carlo algorithms are investigated, and the convergence properties of the algorithms are studied. Two applications of the models are considered: spatial mapping of weed intensities using information available from the previous year; and prediction of radionuclide concentrations on a Pacific island. The work is supplemented by well-documented software, which is a fruitful contribution to the applicability of the models. OFC 's scientific results have been presented at national and international scientific meetings. He has also acted as a teacher at an European Summer School. - Since Sept. 2001, Ole Fredslund Christensen has been employed as a Post-Doc research associate at Department of Mathematics and Statistics, Lancaster University.

Frede Aakmann Tøgersen's PhD project on spatial statistics in the agricultural sciences, scheduled to terminate in the fall of 2001, has been delayed. Thesis submission is now scheduled for the spring of 2002. In 2001 Frede Aakmann Tøgersen and Rasmus Waagepetersen studied spatial deconvolution of yield metre data. The proposed methodology has an application in precision agriculture. Due to some inherent numerical difficulties of the methods studied, the project on spatial deconvolution has still not been completed, but some intermediate results will be presented in a research paper as part of the PhD project. The goal is to complete the work on spatial deconvolution during 2002 by submitting a revised version of the research paper to an international statistical journal. Besides this, Frede Aakmann Tøgersen has started to work with spatial process models (kriging), where the covariate information has not been measured in the same places as the response variable. This too aims at an application in precision agriculture. The scientific results of Frede Aakmann Tøgersen have been presented at national and international scientific meetings.

Activity report from Anders Ringgaard Kristensen
Michael Höhle, PhD project. The subject of the project is: Temporal influence diagrammes in pig production. In 2001, MH finished his PhD courses at KVL and DTU, but there has also been time for research considerations, as reflected in a paper entitled "Computing bounds on expected utilities for optimal policies based on limited information", co-authored by Dennis Nilsson. The paper has been submitted for publication in a journal.

Thomas Nejsum Madsen, PhD project. In 2001, TNM submitted and defended his PhD thesis "Tools for monitoring growing pigs". Together with B.K. Pedersen he presented part of the work at a conference in Spain in a paper entitled "Modelo de instalaciones y controles que aseguren la trazabilidad en la producción porcina".

A new project, in cooperation between Anders Ringgaard Kristensen and Per Abrahamsen. Research project: Model based decision support in pig production. In a collaboration between the Herd Management Group (Anders Ringgaard Kristensen, Michael Höhle, Thomas Algot Søllested, Per Abrahamsen, Thomas Nejsum Madsen and Dennis Nilsson) at the Dept. of Animal Science and Animal Health, KVL, the Dept. of Agricultural Systems (Erik Jørgensen), DJF, and Aalborg University (Dennis Nilsson), the following results have been achieved:

Balance sheet 2001 and budget 2002

Within the PIFT programme the Danish Research Councils have contributed 1.2 million DKR, which have contributed primarily the last year of two PhD students in Aalborg and Foulum (cf. Jesper Møllers report) and one year postdoc (cf. Anders Ringgaard Kristensens report).

See APPENDIX for a provisory balance sheet for Dina for 2001 and a proposed budget for 2002.
