ANAC 2017: Repeated Multilateral Negotiation League

The Automated Negotiating Agents Competition (ANAC) is annually organized competition to facilitate the research on automated negotiation. This paper presents the ANAC 2017 Repeated Multilateral Negotiation League. As human negotiators do, agents are supposed to learn from their previous negotiations and improve their negotiation skills over...

ANAC 2018: Repeated Multilateral Negotiation League

This is an extension from a selected paper from JSAI2019. There are a number of research challenges in the field of Automated Negotiation. The Ninth International Automated Negotiating Agent Competition encourages participants to develop effective negotiating agents, which can negotiate with multiple opponents more than once. This paper...

The Challenge of Negotiation in the Game of Diplomacy

The game of Diplomacy has been used as a test case for complex automated negotiations for a long time, but to date very few successful negotiation algorithms have been implemented for this game. We have therefore decided to include a Diplomacy tournament within the annual Automated Negotiating Agents Competition (ANAC). In this paper we...

Turbulence statistics of turbulent boundary layer flow following injection of drag-reducing surfactant solution

To investigate streamwise variations of turbulence statistics in the wide range of the drag reduction ratio for the zero-pressure-gradient turbulent boundary layer flow due to the injection of drag-reducing nonionic surfactant solutions, we performed the laser-Doppler velocimetry (LDV) measurement at a new experimental apparatus with the larger...

Schnelle Rasterkraftmikroskopie durch moderne Regelungstechnik und mechatronische Systemintegration

In atomic force microscopy (AFM) high-performance and high precision control of the scanning-system is crucial. At high imaging speeds the dynamic behaviour of the scanner may cause imaging artefacts limiting the maximum imaging rate. This contribution discusses recent improvements for faster imaging by utilizing modern mechatronic and control...

Cavitation patterns on a plano-convex hydrofoil in a high-speed cryogenic cavitation tunnel

Multidisciplinary design optimization of wing shape with nacelle and pylon

A Multidisciplinary Design Optimization (MDO) system for a wing with nacelle and pylon is developed. The present MDO system is based on the integration of Computational Fluid Dynamics (CFD) codes and NASTRAN based an aeroelastic-structural interface code. The Kriging model is employed to save the computational time of objective function...

Automatic parallelization of finite element CFD code using HPC middleware

Computational fluid analysis requires huge amounts of computational resources. However, for the usual developer, parallelization is difficult as it requires special programming skills. In this study, the “HPC Middleware” is employed, which supports parallelization and optimizations for easily developing parallel code. The parallel efficiency of...

Efficient Domain Decomposition Method for Acoustic Scattering in Multi-Layered Media

The time-harmonic acoustic scattering in multi-layered media is modeled with an inhomogeneous Helmholtz equation for the pressure field. For example, such problems result from acoustic geological surveys. The exterior problem is truncated into a rectangle and an absorbing boundary condition is posed on its boundaries. A low-order finite...

Process for treating nitrogen oxide-containing gas using a cerium zeolite

The invention relates to a process for treating nitrogen oxide-containing gas substantially having a temperature in the range of 300-560 DEG C, for instance exhaust gases of gas engines or off-gases of power plants, in which the gas is passed over a cerium-containing zeolite catalyst in the presence of substantially an excess of a NH-containing...
