The paper gives a number of SAM examples, demonstrating the authoring of simple animated vir- tual 3D scenarios.}}, author = {{Geiger, Christian and Lehrenfeld, Georg and Müller, Wolfgang}}, booktitle = {{Proceedings of the Annual Conference for the Computer Human Interaction}}, title = {{{Authoring Communicating Agents in Virtual Environments}}}, year = {{1998}}, } @inproceedings{38427, author = {{Sandel, D and Hinz, S and Yoshida-Dierolf, M and Graser, J and Noé, Reinhold and Beresnev, L and Weyrauch, T and Haase, W}}, booktitle = {{24TH EUROPEAN CONFERENCE ON OPTICAL COMMUNICATION, VOL 1-3: VOL 1: REGULAR AND INVITED PAPERS; VOL 2: TUTORIALS AND SYMPOSIUM PAPERS; VOL 3: POSTDEADLINE PAPERS}}, isbn = {{84-89900-14-0}}, pages = {{555--556}}, title = {{{10-Gb/s PMD compensation using deformed-helical ferroelectric liquid crystals}}}, year = {{1998}}, } @article{38412, author = {{Noé, Reinhold and Sandel, D and Yoshida-Dierolf, M and Hinz, S and Glingener, C and Scheerer, C and Schopflin, A and Fischer, G}}, issn = {{0013-5194}}, journal = {{ELECTRONICS LETTERS}}, number = {{25}}, pages = {{2421--2422}}, title = {{{Polarisation mode dispersion compensation at 20Gbit/s with fibre-based distributed equaliser}}}, doi = {{10.1049/el:19981670}}, volume = {{34}}, year = {{1998}}, } @article{38336, author = {{Sandel, D and Yoshida-Dierolf, M and Noé, Reinhold and Schopflin, A and Gottwald, E and Fischer, G}}, issn = {{0013-5194}}, journal = {{ELECTRONICS LETTERS}}, number = {{23}}, pages = {{2258--2259}}, title = {{{Automatic polarisation mode dispersion compensation in 40Gbit/s optical transmission system}}}, doi = {{10.1049/el:19981526}}, volume = {{34}}, year = {{1998}}, } @article{38344, author = {{Sandel, D and Noé, Reinhold and Heise, G and Borchert, B}}, issn = {{0733-8724}}, journal = {{JOURNAL OF LIGHTWAVE TECHNOLOGY}}, number = {{12}}, pages = {{2435--2442}}, title = {{{Optical network analysis and longitudinal structure characterization of fiber Bragg grating}}}, doi = {{10.1109/50.736631}}, volume = {{16}}, year = {{1998}}, } @article{38286, author = {{Sandel, D and Yoshida-Dierolf, M and Noé, Reinhold and Schopflin, A and Gottwald, E and Fischer, G}}, issn = {{0013-5194}}, journal = {{ELECTRONICS LETTERS}}, number = {{23}}, pages = {{2258--2259}}, title = {{{Automatic polarisation mode dispersion compensation in 40Gbit/s optical transmission system}}}, doi = {{10.1049/el:19981526}}, volume = {{34}}, year = {{1998}}, } @article{38294, author = {{Sandel, D and Noé, Reinhold and Heise, G and Borchert, B}}, issn = {{0733-8724}}, journal = {{JOURNAL OF LIGHTWAVE TECHNOLOGY}}, number = {{12}}, pages = {{2435--2442}}, title = {{{Optical network analysis and longitudinal structure characterization of fiber Bragg grating}}}, doi = {{10.1109/50.736631}}, volume = {{16}}, year = {{1998}}, } @inproceedings{39493, abstract = {{This article presents the animated visual 3D programming language SAM (Solid Agents in Motion) for parallel systems specification and animation. A SAM program is a set of interacting agents synchronously exchanging messages. The agent's behaviour is specified by means of production rules with a condition and a sequence of actions each. Actions are linearly ordered and execute when matching a rule. In SAM, main syntactic objects like agents, rules, and messages are 3D. These objects can have an abstract and a concrete, solid 3D presentation. While the abstract representation is for programming and debugging, the concrete representation is for animated 3D end-user presentations. After outlining the concepts of SAM this article gives two programming examples of 3D micro worlds and an overview of the programming environment.}}, author = {{Geiger, Christian and Müller, Wolfgang and Rosenbach, W.}}, booktitle = {{Proceedings of the IEEE Symposium on Visual Languages}}, isbn = {{0-8186-8712-6}}, keywords = {{Animation, Computer languages, Solids, Concrete, Application software, Virtual reality, Programming profession, Switches, Visualization, Debugging}}, location = {{Halifax, Canada}}, title = {{{SAM - An Animated 3D Programming Language}}}, doi = {{10.1109/VL.1998.706167}}, year = {{1998}}, } @inproceedings{38446, author = {{Noé, Reinhold and Sandel, D and Yoshida-Dierolf, M and Hinz, S and Glingener, C and Scheerer, C and Schopflin, A and Fischer, G}}, booktitle = {{24TH EUROPEAN CONFERENCE ON OPTICAL COMMUNICATION, VOL 1-3: VOL 1: REGULAR AND INVITED PAPERS; VOL 2: TUTORIALS AND SYMPOSIUM PAPERS; VOL 3: POSTDEADLINE PAPERS}}, isbn = {{84-89900-14-0}}, pages = {{B157--B159}}, title = {{{Fiber-based distributed PMD compensation at 20 Gb/s}}}, year = {{1998}}, } @article{43343, abstract = {{In his Comment on our work Glutsch raises, on the basis of a calculation for a dimerized three-dimensional superlattice, four points: (1) odd-parity excitons do not contribute to optical absorption, (2) there are no forbidden single-particle transitions, (3) there is a coupling of the e1-hh2 exciton (called ¯X in Ref. 1) to the underlying e1-hh1 continuum that leads to a Fano resonance, and (4) the extension of the exciton wave function is infinite in an all space directions rather than having a small extension.
