OZ is a distance learning environment far lectures, seminaries, and exercises in computer science at Humboldt-Universit}', where "OZ" nieans distributed in space (ortsverteilt) and independent of tirne (zeitversetzt). The facus is on computer-"exercises", which has certain implications on the technical setiip: the back channel is very important and the teacher's presentation as well as the študent's computer screens is visible on both places. Different modes ofuse are possible. Two rooms at
more &raquo; ... erent campuses ofthe university are connected by the universities interna! high-bandwidth, btit non-reserved, TCP/IP-connection. Each one is eguipped with two data projectors, where one is used as white board mirroring the teacher's or a študent's computer screen, while the other shows the teacher and the opposite room inhabitants. Each room has its own control computer that is also used far video or audio streaming. By the iise of\vireless connected laptops a comfartable degree offreedom far teachers and students is achieved. Despite this, we use low-cost hardware and standard software wherever possible. The audio-taped lectures are combined with the screen materials, moslly PowerPoint slides enhanced with QuickTime media, so that lectures as well as other stored materials are accessible via Internet. After more than two years of thorough experimenls the installalion has reached now a state where it is relatively stable, so that it is transferred nowfor regular use in our teaching activities There is a growing expectation from distance learners Ihat their learning and teaching environment will be on-line. Limitations on bandwidth to the home has so far constrained the richness of such environments. A hybrid solution to this problem combines the immediacy of the Internet with the versatility ofDVD Technology. This versatility allows the disc-based material to be integrated with web based material or used off-line as a self-contained learning environment Ali content which is not Computer dependant such as audio-visual material, can be viewedwith a domestic DVDplayerfrom the same DVD disc. As part ofthe Virtual University of Finland, the Connet framework offers undergraduate courses in Cognitive Science. The studies are rnainly organized as vveb-based courses or collaborative študent projects. In the basic studies component, a študent completes four one credit methodology courses and chooses a related assignment worth three credits for one of them. One of the methodology courses is entitled Networks in Learning Organization. It will be delivered entirely on the web, and it also will serve as a pilot course to help design other methodology courses. This paper v/ill first briefly discuss the theoretical foundations of learning organizations and organizational learning. Then, we will review the role of networks as the technological foundation of a learning organization and continue by discussing the use of educational technology to support organizational learning and learn about it. Finally, we will describe the structure and the methods ofthe course and present topics that form the starting point far the discourse within the lnformatica25 (2001) 165-171 165 Programming (seven credits). Instruction is almost entirely given over the Web. The students folloM' a schedule given in the web sile, learn the related chapters from their textbooks, and return the exercises by strict deadlines. The students live as far as a hiindred kilometers a\vayfrom the university, and their local high schools have not been able to hire any gualifiedprogramming teachers. Wefound a solution to this problem by organizing on-line teachers at the university to answer students' guestions, and assigning tutors, who had hardly any experience in programming, to encourage the students al the local schools. To intensif' the learning outcomes, we are planning to use three different learning tools in the web-based course environment: Excel, Jeliot and BlueJ. Each of them can be usedfor understanding a given program visually. In particular, the environments serve as virtual laboratories for real problems: the students can study their o\vn programs. At the Universit}' of Joensuu, the course slarted in August 2000. Out of the 80 enrolled students, more than 65 were active after the first three months. Altogether, the course will last for 16 months. Students' activity and commitment to their studies indicate that the approach chosen to teach programming has proved to be efficient. The U. W.B. has developed an information and database syslem, supporting the internal Credit Accumulation and Transfer System (CA TS). The syslem primarily supports an on-line študent registration to courses within the framework of the existing limetable, and fiirther provides a support for designing and filing study programmes, timetables, študent records, agenda of admission and alumni etc. We give a survey of basic features ofthe system and ofthe history ofits development and we present basic rules ofthe internal CA TS that have to be followed by eveiy instilution that wants to adopt the system. The system has been already installed at 5 furlher Universities in the Czech Republic. Building a data warehouse for a large decentralized university such as the University of Ljubljana is an attractive challenge, but also a risky and demanding task. Experience has shown that projects attempting to integrate data are especially vulnerable to data quality issues. Therefore, before embarking on a data warehouse initiative a thorough quality assessment ofthe source data is necessaij. We describe how the assessment criteria based on the Total Qiiality data Management Methodology were adapted to our specific needs and used to determine the quality of študent records data at two member institutions, viz. the Faculty of Computer and Information Science, and the Faculty of Electrical Engineering. The most important results of the assessment are described and proposals are given for further activities. The assessment has shown that the študent records data at the Faculty of Computer and Information Science and Faculty of Electrical Engineering are good enough to be used as source for the global warehouse at the imiversity level after some data cleansing takes plače. Additionally, special attention must be devoted to the integration ofsuch data that are replicated at many individual departments (viz. employees, subjects taught, and students). Therefore, we propose that a unique coding schemefor ali employees, students, and subjects taught be defined in thefirst step ofthe data warehouse design, and an ongoing data quality management process is established clearly defining the roles and responsibilities ofall personnel involved. We describe a high performance/low priče "computer cluster" named Beowulf Cluster. This kind of device was initially developed by T. Sterling and D. Becker (N.A.S.A) and it is a kind of cluster built primarily out of commodity hardware components, running an OSS (Open Source Software) operating system like Linux or FreeBSD, interconnected by a private high-speed network, dedicated to running high-performance computing tasks. We will show several advantages ofsuch a device, among them we can mention very high performance-price ratio, easy scalability, recyclingpossibilities ofthe hardware components and guarantee of iisability/upgradeability in the medium and long-term future. Ali these advantages make it specially suitable for the university environment and, thus, we make a description about the implementation of a Beowulf Cluster using commodity eguipment dedicated to run highperformance computing tasks at our imiversity focusing on the different areas of application of this device that range from prodiiction of high quality multimedia content to applications in numerical simidation in engineering. JVilh today's widespread availability of networked multimedia potenlials embedded in an infrastructure of qualitative siiperior kind the distribution ofprofessionally slyled multimedia streams hasfallen in the realm ofpossibility. This paper presents a prolotypic environment -both model and runtime systemfor procešsing composite media streams variably composed of midtimedia data objects. The system consists ofan intelligent media database, a IVeb-authoring tool, a time directed presentation stream and is based on a hypermedia data model ofreusable object components. The plug-in free runtime system is designed as a pure JA VA implemenlation. Further educational applications of oiir architecture are presented, as well. The FEIDHE project aims at spečijying what it will take to implement a puhlic key infrastructure (PKI) based Identification system with smart cards in Finnish higher education. Main drivers of the project are data security, flexible use of electronic resources over the network and the national PKI initiative FINEID (Finnish Electronic Identification). The project is looking far a way to manage Identification and authentication when accessing electronic resources and services over networks. [4] James M. Boyle, Terence J. Harmer, and Victor L.

We consider main properdes of a neural field whose state is determined by a vector of some topological space (such as Banach or Hilbert ones). Dynamics of the field (tirne evolution of its state) is associated with information processing and mental phenomena. We formulate the learning problem for neural fields and offer several solutions that are generalizations of learning algorithms proposed for neural networks before. The state vector of a neural field is represented in a form like in quantum theories, which gives a clue to a kind of supersymmetry, viz symmetry between bosonic and fermionic modes ofexcitation ofthe neural field. An evolution equation for a field function is suggested. A minimal architecture ofa cognitive system is proposed which comprises perceptual, lexical and semantic subsystems. It is suggested to treat the meaning of a piece of information as a code associated with a settled field function produced by a semantic neural network. Mobile agents can be regarded as software components which can move from bost to bost to perform computations. Research over tbe past balf-decade bas found the mobile agent paradigm to be useful for many applications. This paper aims to show the broad applicability of mobile agents for enterprise dis tributed applications. It first provides an overview of mobile agent usage in three types of enterprise applications: intra-organizational, inter-organizational and customer-to-business, with focus on data management, distributed parallel processing, computer-supported collaborative work, virtual enterprises, and customer-facing systems. Tben, we discuss issues and future work. We match a template depicting a "bullflag" 60-day price behavior to closing prices ofthe New Vork Stock Exchange Composite Index to detect biiying opportunities at a 20 trading day horizon. The results ofthe experiment indicate that the technique is capable ofachieving results which are superior to those attained by random choice. Statistical results are significant. The paper constitutes evidence that the stock markets are not efficient. A digital neural net\vork architecture is presented \vhich is based on three-dimensional massively parallel opto-electronic circuits. A suitable optical interconnect syslem and the structure ofthe reguired electronic circuits is specified. For this system general formulas for the performance of such a neural network architecture are determined. A parameter study using current technological limitations and timing values from electronic implementation is carried out. Based on this analysis it is shown that this novel type of neuro-architecture that is using 3D massively parallel opto-electronic circuits shows performance rates ofup to one magnititde higher Ihan systems using digital neurochips based onfully electronic implementation.
