Der Artikel gibt einen Überblick über den Stand der Diskussion und der Entwicklung des Open Access an den Hochschulen. Ein besonderer Schwer- punkt liegt auf der Darstellung des Ausbaus der institutionellen Repositorien und des Umgangs mit Open-Access-Zeitschriften sowie in der kurzen Beschreibung der Informationsplattform open-access.net.In einem Ausblick werden die Schritte benannt, die in der nahen Zukunft von den Hochschulbibliotheken und den beteiligten Akteuren gegangen werden müssen, um das Zugriffsrecht auf wissenschaftliche Publikationen zu erhalten.Wed Oct 29 14:07:38 CET 2008Information zwischen Kultur und Marktwirtschaftt413-432Open Access – die Revolution im wissenschaftlichen Publizieren?2004Open_Access wismasys0809 Die Zunahme der wissenschaftlichen Disziplinen, die weiterhin stark ansteigende Literaturproduktion und die Zeitschriftenkrise der Bibliotheken haben die Akteure veranlasst nach neuen Modellen für die Publikation wissenschaftlicher Ergebnisse zu suchen. Unter dem Begriff von Open Access verbergen sich dabei eine ganze Reihe verschiedener Modelle. Die Spannbreite reicht dabei von einfachen institutionellen Dokumentenservern bis zum vollständig redigierten E-Journal, von der low budget Version bis zum kommerziellen Open Access Produkt. Der Vortrag zeigt als Synthese das Open Access Modell der Zentralbibliothek im Forschungszentrum Jülich, das erfolgreiche Publikationssysteme nicht ignoriert und dennoch die Idee der freien Zugänglichkeit zu Informationen umsetzt.Thu Oct 02 13:14:42 CEST 2008AugustDer freie (kostenlose) Zugang zu Publikationen aus Wissenschaft und Bildung im Internet über Open Access (OA): Schwerpunkt Landwirtschaft2008e-journals openaccess oa open-access-zeitschriften open_access open-access-journals Freier und kostenloser Zugang zum Wissen der Welt für alle? Erhalten wir dieses im Internetzeitalter nicht ohnehin unkompliziert und umfassend, wenn wir eine Suchmaschine, zumeist Google, einsetzen? Überhaupt wächst die Anzahl der indexierten Webseiten der Marktführer Google, Yahoo, MSN exponentiell an und erreicht im Fall von Google bereits eine mehrstellige Zahl in Milliardenhöhe1. Wozu sich also mit weiteren Phänomenen und Entwicklungen im Bereich des Wissensmanagements beschäftigen, wenn Suchmaschinen wie Google mit gigantischem Aufwand ständig weiterentwickelt werden, um die Suche noch einfacher zu gestalten und die Suchergebnisse noch näher an die vermeintlichen Benutzererfordernisse anzupassen ?Tue Sep 09 11:50:50 CEST 2008Journal of Virtual Reality and Broadcasting18Fitting 3D morphable models using implicit representations42007non-rigid_registration 2007 implicit_surface_representations Digital_Peer_Publishing DiPP Peer_Reviewed 4.2007 Journal_of_Virtual_Reality_and_Broadcasting [BV07] JVRB computer_graphics Open_Access 3D_Morphable_Models 4(2007)18 We consider the problem of approximating the 3D scan of a real object through an affine combination of examples. Common approaches depend either on the explicit estimation of point-to-point correspondences or on 2-dimensional projections of the target mesh; both present drawbacks. We follow an approach similar to [IF03] by representing the target via an implicit function, whose values at the vertices of the approximation are used to define a robust cost function. The problem is approached in two steps, by approximating first a coarse implicit representation of the whole target, and then finer, local ones; the local approximations are then merged together with a Poisson-based method. We report the results of applying our method on a subset of 3D scans from the Face Recognition Grand Challenge v.1.0.Tue Aug 12 16:49:39 CEST 2008Journal of Virtual Reality and BroadcastingJune{\tt urn:nbn:de:0009-6-13308,}, ISSN 1860-20374RFIDice - Augmenting Tabletop Dice with RFID52008[HL08] RFID 5.2008 Dice PerGames2007 Unobtrusive_Input_Devices DiPP Peer_Reviewed Tabletop 5(2008)4 Ubiquitous_Computing Journal_of_Virtual_Reality_and_Broadcasting JVRB Digital_Peer_Publishing_Initiative Open_Access Pervasive_Gaming Game_Design Digital_Peer_Publishing_License Augmented dice allow players of tabletop games to have the result of a roll be automatically recorded by a computer, e.g., for supporting strategy games. We have built a set of three augmented-dice-prototypes based on radio frequency identification (RFID) technology, which allows us to build robust, cheap, and small augmented dice. Using a corresponding readout infrastructure and a sample application, we have evaluated our approach and show its advantages over other dice augmentation methods discussed in the literature.Tue Aug 12 16:46:48 CEST 2008Journal of Virtual Reality and BroadcastingJuly{\tt urn:nbn:de:0009-6-14197,}, ISSN 1860-20375Multi-Mode Tensor Representation of Motion Data520082008 5.2008 [KTMW08] DPPL DiPP Peer_Reviewed 5(2008)5 Motion_Data Journal_of_Virtual_Reality_and_Broadcasting JVRB Digital_Peer_Publishing_Initiative Open_Access Motion_Capture Digital_Peer_Publishing_License MoCaDa In this paper, we investigate how a multilinear model can be used to represent human motion data. Based on technical modes (referring to degrees of freedom and number of frames) and natural modes that typically appear in the context of a motion capture session (referring to actor, style, and repetition), the motion data is encoded in form of a high-order tensor. This tensor is then reduced by using N-mode singular value decomposition. Our experiments show that the reduced model approximates the original motion better then previously introduced PCA-based approaches. Furthermore, we discuss how the tensor representation may be used as a valuable tool for the synthesis of new motions.Tue Jul 08 11:37:04 CEST 2008PLoS Biology5Citation Advantage of Open Access Articles42006citation_impact open_access Tue Jul 08 11:34:56 CEST 2008Learned PublishingJanuary295--100In a paperless world a new role for academic libraries: providing open access182005open_access Academic libraries should be considered research tools, co-evolving with technology. The Internet has changed the way science is communicated and hence also the role of libraries. It has made it possible for researchers to provide open access (OA) (i.e.toll-free, full-text, online access,web-wide) to their peer-reviewed journal articles in two different ways: (i) by publishing in them in OA journals, and (ii) by publishing them in non-OA journals but also self-archiving them intheir institutional OA archives. Librarians are researchers' best allies in both of these strategies.Examples of these strategies are described. We conclude that an official mandate for OA provision is necessary to accelerate its growth and thereby the growth of research usage and impact worldwide.Tue Jul 08 11:32:17 CEST 2008First Monday10A critical theory of open access: Libraries and electronic publishing.122007open_access Tue Jul 08 11:31:24 CEST 2008ELPUBconf/elpub/2008178-186Global annual volume of peer reviewed scholarly articles and the share available via different Open Access options.2008open_access Tue Jul 08 11:29:47 CEST 2008Research Evaluation2127-132Constructing experimental indicators for open access documents152006open_access The ongoing paradigm change in the scholarly publication system makes it necessary to construct alternative evaluation criteria/metrics which appropriately take into account the unique characteristics of electronic publications and other research output in digital formats. Today, major parts of scholarly open access (OA) publications and the self-archiving area are not well covered in traditional citation and indexing databases. The growing share and importance of freely accessible research output demands new approaches/metrics for measuring and evaluating these new types of scientific publication. We propose a simple quantitative method which establishes indicators by measuring the access/ download pattern of OA documents and other web entities of a single web server. The experimental indicators are constructed, based on standard local web usage data. This new type of web-based indicator is developed to model the specific demand for better study/evaluation of the accessibility, visibility and interlinking of open accessible documents. We conclude that escience will need new stable e-indicators.Mon Jul 07 15:45:28 CEST 2008Research Evaluation2127-132Constructing experimental indicators for open access documents152006nutzung open_access gelesen logfile_analyse indikatoren The ongoing paradigm change in the scholarly publication system makes it necessary to construct alternative evaluation criteria/metrics which appropriately take into account the unique characteristics of electronic publications and other research output in digital formats.

But, a computer animation is not only a numerical simulation based on classical mechanics since it follows a precise story-line. One common way to define aims in an animation is to add geometric constraints. There are several methods to manage these constraints within a physically-based framework. In this paper, we present an algorithm for constraints handling based on Lagrange multipliers. After few remarks on the equations of motion that we use, we present a first algorithm proposed by Platt. We show with a simple example that this method is not reliable. Our contribution consists in improving this algorithm to provide an efficient and robust method to handle simultaneous active constraints.Fri Feb 29 09:05:41 CET 2008Journal of Virtual Reality and BroadcastingFebruary{\tt urn:nbn:de:0009-6-12799,}, ISSN 1860-203718Fitting 3D morphable models using implicit representations42007non-rigid_registration 2007 implicit_surface_representations Digital_Peer_Publishing DiPP Peer_Reviewed 4.2007 Journal_of_Virtual_Reality_and_Broadcasting [BV07] JVRB computer_graphics Open_Access 3D_Morphable_Models 4(2007)18 We consider the problem of approximating the 3D scan of a real object through an affine combination of examples.

For a believable appearance, consistent lighting of the virtual objects is required. We present an augmented reality system that displays virtual objects with consistent illumination and shadows in the image of a simple webcam. We use two high dynamic range video cameras with fisheye lenses permanently recording the environment illumination. A sampling algorithm selects a few bright parts in one of the wide angle images and the corresponding points in the second camera image. The 3D position can then be calculated using epipolar geometry. Finally, the selected point lights are used in a multipass algorithm to draw the virtual object with shadows. To validate our approach, we compare the appearance and shadows of the synthetic objects with real objects.Wed Feb 06 16:48:38 CET 2008Journal of Virtual Reality and BroadcastingJanuary{\tt urn:nbn:de:0009-6-12754,}, ISSN 1860-203714Augmenting a Laser Pointer with a Diffraction Grating for Monoscopic 6DOF Detection42007Interaction DiPP Peer_Reviewed 4.2007 Journal_of_Virtual_Reality_and_Broadcasting 4(2007)14 6DOF_Detection JVRB Digital_Peer_Publishing_Initiative Open_Access Laser_Pointer Digital_Peer_Publishing_License [LB07] Virtual_Environments This article illustrates the detection of 6 degrees of freedom (DOF) for Virtual Environment interactions using a modified simple laser pointer device and a camera. The laser pointer is combined with a diffraction grating to project a unique laser grid onto the projection planes used in projection-based immersive VR setups. The distortion of the projected grid is used to calculate the translational and rotational degrees of freedom required for human-computer interaction purposes.Mon Jan 21 01:45:07 CET 2008IMS Bulletin4-5{IMS Journals on arXiv}33 Issue 62004Dept_Statistics_Berkeley Dept_Mathematics_Berkeley author_Pitman__Jim open_access scholarly_communication Mon Jan 21 01:43:38 CET 2008PreprintA strategy for open access to society publications2004Dept_Statistics_Berkeley Dept_Mathematics_Berkeley author_Pitman__Jim open_access scholarly_communication Scholarly societies are typically non-profit organizations which seek a stable and sustainable balance between two basic long term objectives: on the one hand to promote and develop a particular field of knowledge by widespread dissemination of high quality publications in that field, and on the other hand to sustain themselves as organizations and support various other beneficial activities besides publication. As chair of the publications committee of one such society, the Institute of Mathematical Statistics (IMS), I am looking for ways to achieve this balance, and seeking advice from others with the same intent.Sat Jan 05 14:12:06 CET 2008Washington, D.
