This paper analyzes different experiences of space by which memory of Holocaust could be passed on. The Memorial for the murdered Jews of Europe in Berlin gives visitors the feeling of insecurity and overwhelms them with monumentality. For that reason it is criticized as reflecting the other side of German memory: The Third Reich’s megalomania and dream about power. The Hamburger memorial against fascism designed in 1986 by conceptual artists Jochen and Esther Gerz offers quite an opposite experience of space. A twelve-meter-high pillar has been established for visitors to sign on it. Once the area was covered by signature it was lowered into the ground till it completely disappeared. The intention of the artists was to put memory not into the monument but into people. Pozdrowienia z Alej Jerozolimskich (Greetings from the Jerusalem Avenue, 2002) by Joanna Rajkowska – a fifteen-meter tall artificial palm tree installed in the centre of Warsaw – is an attempt to infuse with Israel's scenery a Warsaw's street whose name and history sends the observer to the history of the Jews in Poland. In another work called Dotleniacz (Oxygenator, 2007) Rajkowska created an artificial lake with oxygen concentrators, gold fish, flowers and banks. Again, the installation was placed in a very meaningful place – Grzybowski Square – which is strongly connected with Jewish life in Poland as well as Polish anti-Semitism. The synagogue in Poznan was transformed during the Nazi occupation into a swimming pool which it has remained until the present day. This fact ( just like the building) seems to be invisible for most citizens. In 2003 Rafał Jakubowicz changed the fact by projecting a Hebrew inscription הייחש-תכירב (swimming pool) on the façade of the former synagogue. In Berek (The Game of Tag, 1999) by Artur Żmijewski a group of naked men and women of various age play tag. The artist filmed them in two rooms: in a symbolically neutral space and in a gas chamber of a former Nazi death camp. The film is an attempt at breaking the spell of this horrifying and paralysing space.

Poster pokazuje metody komunikacji z czytelnikiem stosowane w Bibliotece Uniwersyteckiej w Poznaniu w technologii mediów cyfrowych. Cyfrowe narzędzia komunikacji stały się bardzo pomocne, niemal niezbędne w pozyskiwaniu nowych czytelników, podtrzymywaniu i rozwijaniu współpracy w społeczności w sieci Web.2.0, zarówno tej globalnej, jak i lokalnej akademickiej. Strona WWW jako statyczna komunikacyjnie jest wspierana przez fora dyskusyjne, chaty, wideokonferencje, warsztaty informacyjne, które są prowadzone w czasie rzeczywistym. Twórczą siłę relacji społecznych z biblioteką rozwinęły interaktywne serwisy społecznościowe (Facebook) oraz komunikatory internetowe integrowane na platformie Ask a Librarian. Biblioteka stała się Biblioteką 2.0 ukierunkowaną na komunikację z czytelnikiem. Aktywne uczestnictwo i udział czytelników przy tworzeniu zasobów naukowych wdrożyliśmy w projekcie instytucjonalnego repozytorium - Adam Mickiewicz Repository (AMUR). Biblioteka zmienia się dla czytelników i z czytelnikami. Wykorzystywane platformy i serwisy społecznościowe dostarczają unikatowych danych o nowych potrzebach informacyjnych i oczekiwaniach docelowego Patrona 2.0, co skutkuje doskonaleniu usług istniejących i tworzeniu nowych. Biblioteka monitoruje usługi i potrzeby czytelników przez prowadzone badania społeczne. Technologie cyfrowe stosowane w komunikacji sprawiają, iż biblioteka staje się bliższa, bardziej dostępna, aby stać się w rezultacie partnerem dla stałych i nowych czytelników. Biblioteka Uniwersytecka w Poznaniu bierze udział w programach europejskich w zakresie katalogowania i digitalizacji zasobu biblioteki cyfrowej WBC, w zakresie wdrożenia nowych technologii i rozwiązań podnoszących jakość usług bibliotecznych, działalności kulturotwórczej (Poznańska Dyskusyjna Akademia Kominksu, deBiUty) i edukacji informacyjnej. Biblioteka Uniwersytecka w Poznaniu jest członkiem organizacji międzynarodowych: LIBER (Liga Europejskich Bibliotek Naukowych), IAML (Stowarzyszenie Bibliotek Muzycznych, Archiwów i Ośrodków Dokumentacji), CERL - Europejskie Konsorcjum Bibliotek Naukowych.

Heun Hans-Georg, Die Organisation und Ieitung der Arbeit mit audiovisuellen lehr- und Ißrnmitteln an der Humboldt-Universität zu Berlin und an anderen Hochschulen in der DDR (Organization and conducting of work with audiovidual aids at the Humboldt University and other schools of higher education in the German Democratic Republic), „Neodidagmata” XX, Poznan 1991, Adam Mickiewicz University Press, pp. 131-136. ISBN 83-232-0302-4. ISBN 0077-653X. Received: November 1987. Audiovisual aids have become now an indispensable help for teachers. The centre of audiovisual aids at the Humboldt University in Berlin performs the following tasks: a) production of audiovisual materials; b) technical service of classes and lectures and seminars and repairing of the equipment; c) information on new audiovisual aids and lending services; d) training of students and university teachers in operating audiovisual aids; e) studies on application of audiovisual aids in schools of higher education.

This paper presents an Invariant Information Local Sub-map Filter (IILSF) as a technique for consistent Simultaneous Localisation and Mapping (SLAM) in a large environment. It harnesses the benefits of sub-map technique to improve the consistency and efficiency of Extended Kalman Filter (EKF) based SLAM. The IILSF makes use of invariant information obtained from estimated locations of features in independent sub-maps, instead of incorporating every observation directly into the global map. Then the global map is updated at regular intervals. Applying this technique to the EKF based SLAM algorithm: (a) reduces the computational complexity of maintaining the global map estimates and (b) simplifies transformation complexities and data association ambiguities usually experienced in fusing sub-maps together. Simulation results show that the method was able to accurately fuse local map observations to generate an efficient and consistent global map, in addition to significantly reducing computational cost and data association ambiguities.

Manipulator motion planning is a task which relies heavily on the construction of a configuration space prior to path planning. However when fast real-time motion is needed, the full construction of the manipulator's high-dimensional configu-ration space can be too slow and expensive. Alternative planning methods, which avoid this full construction of the manipulator's configuration space are needed to solve this problem. Here, one such existing local planning method for manipulators based on configuration-sampling and subgoal-selection has been extended. Using a modified Artificial Potential Fields (APF) function, goal-configuration sampling and a novel subgoal selection method, it provides faster, more optimal paths than the previously proposed work. Simulation results show a decrease in both runtime and path lengths, along with a decrease in unexpected local minimum and crashing issues.
