Die Vorteile gegenüber traditionellen Technologien wie beispielsweise LCD-Displays bestehen zum einen in niedrigeren Herstellungskosten (niedrigere Produktionskosten und geringere Materialkosten) und einem geringeren Gewicht. Zum anderen entsteht eine bessere Lesbarkeit, da sich Reflexion, Kontrast und mögliche Betrachtungswinkel verbessern bzw. vergrößern. Diese Potenziale können bei Anzeigetafeln, Computerdisplays und mobilen Endgeräten ausgeschöpft werden. Mit der Eigenschaft, fast beliebige Materialien als Trägermedium zu verwenden, öffnet sich auch die Anwendungsmöglichkeit des biegsamen, elektronischen Mediums für Zeitungen und Zeitschriften.

The special feature of our approach is that it allows an interactive navigation in very large scenes (30 GB/400 million polygons in our benchmark scenes) that cannot be stored in main memory, but only on a local or remote hard disk. Furthermore, it allows interactive rendering of substantially more complex scenes by instantiating objects.\r\n\r\nFor the computation of an approximate image of the scene, a sampling technique is used. In the preprocessing, a so-called sample tree is built whose nodes contain randomly selected polygons from the scene. This tree only uses space that is linear in the number of polygons. In order to produce an image of the scene, the tree is traversed and polygons stored in the visited nodes are rendered. During the interactive walkthrough, parts of the sample tree are loaded from local or remote hard disk.\r\n\r\nWe implemented our algorithm in a prototypical walkthrough system. Analysis and experiments show that the quality of our images is comparable to images computed by the conventional z-buffer algorithm regardless of the scene topology."}],"publication":"Proceedings of the ACM symposium on Virtual reality software and technology  - VRST '02","type":"conference","doi":"10.1145/585740.585764","title":"The randomized sample tree: a data structure for interactive walkthroughs in externally stored virtual environments","date_created":"2020-04-09T10:10:36Z","author":[{"first_name":"Jan","last_name":"Klein","full_name":"Klein, Jan"},{"first_name":"Jens","last_name":"Krokowski","full_name":"Krokowski, Jens"},{"first_name":"Matthias","full_name":"Fischer, Matthias","id":"146","last_name":"Fischer"},{"first_name":"Michael","last_name":"Wand","full_name":"Wand, Michael"},{"full_name":"Wanka, Rolf","last_name":"Wanka","first_name":"Rolf"},{"first_name":"Friedhelm","last_name":"Meyer auf der Heide","id":"15523","full_name":"Meyer auf der Heide, Friedhelm"}],"date_updated":"2022-01-06T06:52:51Z","citation":{"chicago":"Klein, Jan, Jens Krokowski, Matthias Fischer, Michael Wand, Rolf Wanka, and Friedhelm Meyer auf der Heide. “The Randomized Sample Tree: A Data Structure for Interactive Walkthroughs in Externally Stored Virtual Environments.” In <i>Proceedings of the ACM Symposium on Virtual Reality Software and Technology  - VRST ’02</i>, 2002. <a href=\"https://doi.org/10.1145/585740.585764\">https://doi.org/10.1145/585740.585764</a>.","ieee":"J.

This paper summarizes our key efforts to build a large vocabulary continuous speech recognition system for the heterogenous BN task without inducing undesired complexity and computational resources. These key efforts included: - automatic segmentation of the audio signal into speech utterances; - efficient one-pass trigram decoding using look-ahead techniques; - optimal log-linear interpolation of a variety of acoustic and language models using discriminative model combination (DMC); - handling short-range and weak longer-range correlations in natural speech and language by the use of phrases and of distance-language models; - improving the acoustic modeling by a robust feature extraction, channel normalization, adaptation techniques as well as automatic script selection and verification. The starting point of the system development was the Philips 64k-NAB word-internal triphone trigram system. On the speaker-independent but microphone-dependent NAB-task (transcription of read newspaper texts) we obtained a word error rate of about 10\\%. Now, at the conclusion of the system development, we have arrived at Philips at an DMC-interpolated phrase-based crossword-pentaphone 4-gram system. This system transcribes BN data with an overall word error rate of about 17\\%."}],"status":"public"},{"language":[{"iso":"eng"}],"_id":"11731","department":[{"_id":"54"}],"user_id":"44006","abstract":[{"lang":"eng","text":"Currently the future satellite navigation system Galileo and the third generation mobile communications system UMTS are on their way to the market in Europe. cdma2000 is under development in the USA and, furthermore, a new civil GPS signal in L2 band and the new frequency band L5 are added. In a hybrid receiver for satellite navigation and mobile radio communications, the possibility of an additional usage of the mobile radio signals for navigation purposes could also be a remedy to one problem of satellite navigation systems, which is the reduced location accuracy inside of buildings and urban canyons. A hybrid receiver with two fully separated receiver branches would lead to an increased bill of material and to increased power consumption in the receiver. This paper, therefore, introduces a hybrid receiver capable of evaluating Galileo/GPS as well as UMTS/cdma2000 signals with reduced computational efforts.

The receivers treat the reflected paths also reaching the receiver antenna as disturbance which has to be suppressed. Multipath affects the tracking accuracy by resulting in a degeneration of the S-curve of the DLL (delay locked loop). Nowadays the future European systems GALILEO and GPSIIF/III with two new signals are on the way to the market and it is time to think about new receiver structures. Therefore we investigated if it is possible to use multipath for navigation constructively.","lang":"eng"}]},{"_id":"11808","user_id":"44006","department":[{"_id":"54"}],"language":[{"iso":"eng"}],"type":"conference","publication":"International Symposium on Location Based Services for Cellular Users (LOCELLUS 2002)","abstract":[{"text":"Current location methods for cellular communication systems TOA and E-OTD exploit time delays and time differences of various base station signals measured in a mobile phone to determine its location. These methods assume line-of-sight (LOS) connections to all utilized base stations. Since mobile radio channels are mainly characterized by scattered propagation paths and non-line-of-sight (NLOS) propagation, bias errors occur when measured time delays and time differences are utilized in position calculation algorithms. In this paper, the distribution of the time error due to NLOS propagation is estimated based on the channel model proposed in [1]. In combination with actual channel measurements in [2] the NLOS time error and its probability distribution function is estimated. With this information being determined for each received signal, position calculation algorithms can utilize the reliability information to enhance positioning accuracy. [1] L. J. Greenstein, V.
