"Mining Bibliographic Data" - Using Author's Publication History for a Brighter Reviewing Future within Conference Management Systems

2014

International Journal on Advances in Intelligent Systems, Vol.7 (2014), 3 & 4, pp. 609-619

Organizing and managing a conference is a cumbersome and time consuming task. Electronic conference management systems support reviewers, conference chairs and the International Programme Committee members (IPC) in managing the huge amount of submissions. These systems implement the complete workflow of scientific conferences. One of the most time consuming tasks within a conference is the assignment of IPC members to the submissions. Finding the best-suited person for reviewing a paper strongly depends on the expertise of the IPC member. There are already various approaches like "bidding" or "topic matching". However, these approaches allocate a considerable amount of resources on the IPC member side. This article introduces how the workflow of a conference looks like and what the challenges for an electronic conference management are. It will take a close look on the latest version of the Eurographics Submission and Review Management system (SRMv2). Finally, it will introduce an extension of SRMv2 called the Paper Rating and IPC Matching Tool (PRIMA), which reduces the workload for both - IPC members and chairs - to support and improve the assignment process.

3D-Registrierung zum Soll-Ist-Vergleich auf Basis unterschiedlicher Geometriedateiformate

2014

Paul, Lothar (Ed.) et al.: 3D-NordOst 2014 : 17. Anwendungsbezogener Workshop zur Erfassung, Modellierung, Verarbeitung und Auswertung von 3D-Daten. Berlin: GFaI, 2014, pp. 43-52

Anwendungsbezogener Workshop zur Erfassung, Modellierung, Verarbeitung und Auswertung von 3D-Daten (3D-NordOst) <17, 2014, Berlin, Germany>

Der Soll-Ist-Vergleich ist eine notwendige Maßnahme zur Sicherung der Qualität gefertigter Bauteile. Zur Automatisierung des Soll-Ist-Vergleiches sind eine einheitliche Repräsentation der Geometrie und eine robuste 3D-Registrierung notwendig. In diesem Beitrag wird eine Methode zur 3D-Registrierung auf Basis verschiedener Geometriedateiformate großer technischer Objekte vorgestellt. Ausgehend von einem Laserscan (Ist-Modell) und einem CAD-Format (Soll-Modell) wird eine einheitliche Dreiecksrepräsentation generiert. Anhand der einheitlichen Repräsentation, dem weitverbreiteten STL-Format, wird eine dreistufige 3D-Registrierung vorgenommen. In der ersten Stufe werden aus den Dreiecken geeignete Punkte generiert. In der zweiten Stufe werden die Punktwolken anhand von lokalen Merkmalen grob vorregistriert und in der letzten und dritten Stufe diese genau aufeinander registriert. Durch die Anbindung der Funktionalität an eine CAD/CAM Software, wie bspw. DCAM, ergeben sich eine einfach handhabbare 3D-Registrierung und eine Basis für einen anschließenden Soll-Ist-Vergleich.

A Benchmarking Model for Sensors in Smart Environments

2014

Aarts, Emile (Ed.) et al.: Ambient Intelligence : European Conference, AmI 2014. Berlin, Heidelberg, New York: Springer, 2014. (Lecture Notes in Computer Science (LNCS) 8850), pp. 242-257

European Conference on Ambient Intelligence (AmI) <11, 2014, Eindhoven, The Netherlands>

In smart environments, developers can choose from a large variety of sensors supporting their use case that have specific advantages or disadvantages. In this work we present a benchmarking model that allows estimating the utility of a sensor technology for a use case by calculating a single score, based on a weighting factor for applications and a set of sensor features. This set takes into account the complexity of smart environment systems that are comprised of multiple subsystems and applied in non-static environments. We show how the model can be used to find a suitable sensor for a use case and the inverse option to find suitable use cases for a given set of sensors. Additionally, extensions are presented that normalize differently rated systems and compensate for central tendency bias. The model is verified by estimating technology popularity using a frequency analysis of associated search terms in two scientific databases.

A Gesture-Based Door Control Using Capacitive Sensors

2014

Streitz, Norbert (Ed.) et al.: Distributed, Ambient, and Pervasive Interactions : DAPI 2014. Berlin, Heidelberg, New York: Springer, 2014. (Lecture Notes in Computer Science (LNCS) 8530), pp. 207-216

In public places sanitary conditions are always of concern, particularly of surfaces that are touched by a multitude of persons, such as door handles in rest rooms. Similar issues also arise in medical facilities. Doors that open based on presence are common in environments such as shopping malls; however they are not suited for sensitive areas, such as toilet stalls. Capacitive proximity sensors detect the presence of the human body over a distance and can be unobtrusively applied in order to enable hidden gesture-based interfaces that work without touch. In this paper we present a concept for a gesture controlled automated door based on this sensor technology. We introduce the underlying technology and present the concept and electronic components used in detail. Novel interaction patterns and data processing methods allow to open, close, lock and unlock the door using simple gestures. A prototype device has been created and evaluated in a user study.

A Modular Architecture for a Driving Simulator Based on the FDMU Approach

2014

IJIDeM - International Journal on Interactive Design and Manufacturing, Vol.8 (2014), 2, pp. 139-150; First published online: 09 March 2013

The present paper describes the development of a modular and easily configurable simulation platform for ground vehicles. This platform should be usable for the implementation of driving simulators employed both in training purposes and in vehicle components testing. In particular, the paper presents a first architectural model for the implementation of a simulation platform based on the Functional Digital Mock-Up (FDMU) approach. This platform will allow engineers to implement different kinds of simulators that integrate both physical and virtual components, thus achieving the possibility to quickly reconfigure the architecture depending on the hardware and software used and on specific test case needs. The platform has been tested by developing a case study that integrates a motion platform, some I/O devices and a simple dynamic ground vehicle model implemented in OpenModelica.

A New Connection Space for Low-Dimensional Spectral Color Management

2014

Segovia, Maria V. Ortiz (Ed.) et al.: Measuring, Modeling, and Reproducing Material Appearance. Bellingham: SPIE Press, 2014. (Proceedings of SPIE 9018), 90180E-1 - 90180E-6

Multi- or hyper-spectral pixels are usually represented as vectors with high dimensionality. For many applications, not all of these dimensions are actually necessary, and a few values are enough to measure and/or process the pixel with a very good accuracy. In this work, we introduce a new strategy to reduce the dimensionality of spectral images ranging in the visible wavelengths, for purposes of color management. We define a new Interim Connection Space (ICS) that contains only five dimensions, and show that it has numerous advantages over state-of-the-art ICS such as LabPQR. In particular, it allows for a better spectral reconstruction accuracy.

A p-Multigrid Algorithm using Cubic Finite Elements for Efficient Deformation Simulation

2014

Bender, Jan (Ed.) et al.: VRIPHYS 14: 11th Workshop in Virtual Reality Interactions and Physical Simulations. Goslar: Eurographics Association, 2014, pp. 49-58

International Workshop in Virtual Reality Interaction and Physical Simulations (VRIPHYS) <11, 2014, Bremen, Germany>

We present a novel p-multigrid method for efficient simulation of co-rotational elasticity with higher-order finite elements. In contrast to other multigrid methods proposed for volumetric deformation, the resolution hierarchy is realized by varying polynomial degrees on a tetrahedral mesh. We demonstrate the efficiency of our approach and compare it to commonly used direct sparse solvers and preconditioned conjugate gradient methods. As the polynomial representation is defined w.r.t. the same mesh, the update of the matrix hierarchy necessary for co-rotational elasticity can be computed efficiently. We introduce the use of cubic finite elements for volumetric deformation and investigate different combinations of polynomial degrees for the hierarchy. We analyze the applicability of cubic finite elements for deformation simulation by comparing analytical results in a static scenario and demonstrate our algorithm in dynamic simulations with quadratic and cubic elements. Applying our method to quadratic and cubic finite elements results in speed up of up to a factor of 7 for solving the linear system.

A Scalable Rendering Framework for Generative 3D Content

2014

Polys, Nicholas F. (General Chair) et al.: Proceedings Web3D 2014 : 19th International Conference on 3D Web Technology. New York: ACM, 2014, pp. 81-87

Delivering high quality 3D content through a web browser is still a challenge especially when intellectual property (IP) protection is necessary. Thus, the transfer of 3D modeling information to a client should be avoided. In our work we present a solution to this problem by introducing a server-side rendering framework. Only images are transferred to the client, the actual 3D content is not delivered. By providing simple proxy geometry it is still possible to provide direct interaction on the client. Our framework incorporates the Generative Modeling Language (GML) for the description and rendering of generative content. It is then possible to not only interact with the 3D content, but to modify the actual shape within the possibilities of the generative content. By introducing a control layer and encapsulating processing and rendering of the generative content in a so called GML Rendering Unit (GRU) it is possible to provide a scalable rendering framework.

A Survey of Direction-Preserving Layout Strategies

2014

Gutierrez, Diego (Ed.): Proceedings of the 30th Spring Conference on Computer Graphics : SCCG 2014. New York: ACM, 2014, pp. 21-28

In this paper we analyze different layout algorithms that preserve relative directions in geo-referenced networks. This is an important criterion for many sensor networks such as the electric grid and other supply networks, because it enables the user to match the geographic setting with the drawing on the screen. Even today, the layouts of these networks are often created manually. This is due to the requirement that these layouts must respect geographic references but should still be easy to read and understand. The range of available automatic algorithms spans from general graph layouts over schematic maps to semi-realistic drawings. At first sight, schematics seem to be a promising compromise between geographic correctness and readability. The former property exploits the mental map of the user while the latter makes it easier for the user to learn about the network structure. We investigate different algorithms for such maps together with different visualization techniques. In particular, the group of octi-linear layouts is prominent in handcrafted subway maps. These algorithms have been used extensively to generate drawings for subway maps. Also known as Metro Map layouts, only horizontal, vertical and diagonal directions are allowed. This increases flexibility and makes the resulting layout look similar to the well-known subway maps of large cities. The key difference to general graph layout algorithms is that geographic relations are respected in terms of relative directions. However, it is not clear, whether this metaphor can be transferred from metro maps to other domains. We discuss applicability of these different approaches for geo-based networks in general with the electric grid as a use-case scenario
