Recent work has shown the potential for lights to act as simple, yet expressive signaling mechanisms for use in a variety of human-robot applications. However, the wide range of robot shapes and sizes makes it difficult for researchers to quickly prototype and evaluate different light configurations and signal designs. In this work, we present the design of ModLight, a modular research tool consisting of a set of low cost light blocks that can be easily reconfigured to fit a myriad of robots and applications. ModLight also provides researchers, designers, and students with open-source software tools that enable them to visually design new signals and easily integrate them into existing systems. This work also serves to motivate the need for further research in developing light behaviors for use in human-robot interaction. Towards this goal, we present our design rationale including a brief analysis of the signaling needs of several robots and applications. © 2017 IEEE.

In computer vision a reliable recognition and classification of objects is an essential milestone on the way to autonomous scene understanding. In particular, keypoint detection is an essential prerequisite towards its successful implementation. The aim of keypoint algorithms is the identification of such areas within 2-D or 3-D representations of objects which have a particularly high saliency and which are as unambiguous as possible. While keypoints are widely used in the 2-D domain, their 3-D counterparts are more rare in practice. One of the reasons often consists in their long computation *** present a highly parallelizable algorithm for 3-D keypoint detection which can be implemented on modern GPUs for fast execution. In addition to its speed, the algorithm is characterized by a high robustness against rotations and translations of the objects and a moderate robustness against *** evaluate our approach in a direct comparison with state-of-the-art keypoint detection algorithms in terms of repeatability and computation time. © Springer International Publishing Switzerland 2016.

The average portfolio structure of institutional investors is shown to have properties which account for transaction costs in an optimal way. This implies that financial institutions unknowingly display collective rationality, or Wisdom of the Crowd. Individual deviations from the rational benchmark are ample, which illustrates that system-wide rationality does not need nearly rational individuals. Finally we discuss the importance of accounting for constraints when assessing the presence of Wisdom of the Crowd. Copyright © 2017, The Authors. All rights reserved.

For annual field crops, the early development phase is crucial in establishing potential crop yield and thus to achieve high yield. Despite its importance, this phase is often neglected in current crop models that focus on later stages and on how plants produce biomass and allocate it to the different organs after emergence. Modeling stand establishment requires assessing accurately enough the conditions of the seedbed, the top 10 cm of the soil profile that serve as growing medium for germinating seeds and plantlets, which drive early development. In this zone, atmospheric conditions generate intense energy and water fluxes, results of biophysical phenomena at the soil-atmosphere interface, and consequently rapid and dramatic changes in temperature and water content that are not yet completely understood. Thus, our goal is to propose a modeling approach to improve the estimation of emergence timing by a simulation of the dynamics of seedbed temperature in response to a few standard meteorological factors that can be routinely acquired: global radiation, air temperature, relative humidity, wind speed and precipitation. The use of these five meteorological factors will allow an easier deployment and use of this model at large scale. We developed a soil model that uses the energy balance approach for the soil surface and a system of coupled partial differential equations for heat and water diffusion in the soil. We made the assumption of a homogeneous soil, without vegetation or residue cover. Our results show that this model is able to capture temporal and spatial variations of the soil temperature and the soil water content. Moreover, this model provides the most critical input data for models predicting the dynamics of emergence. Using data of maize (Zea Mays L.), we evaluate three thermal time models with respectively one, two and three parameters to predict the timing to 50 % of emergence and show that the model with one parameter corresponds to more heat-toleran

The International Agency for Research on Cancer classifies radiofrequency (RF) electromagnetic emissions of cell phones as possibly carcinogenic to humans [1] and suggests the use of hands-free devices such as earphones to reduce direct exposure of the brain to such emissions. In this paper, we present the design of a mobile application that exploits persuasive principles to encourage the use of earphones during cell phone calls. We propose different notifications and visualizations aimed at informing the user about her behavior with respect to earphone use and discuss the results of a user study that was aimed at investigating aspects such as understandability, emotional impact, and perceived usefulness of the proposed solutions. Results of the study are used to inform the design of the application. To the best of our knowledge, this is the first investigation of persuasive technologies applied to the reduction of user's exposure to cell phone RF emissions. © 2014 Springer International Publishing.

Parameterized Algorithmics for Computational Social Choice:Nine Research Challenges

Tsinghua science and Technology 2014年第4期19卷 358-373页

Computational Social Choice is an interdisciplinary research area involving Economics, Political science,and Social science on the one side, and mathematics and computer science（including Artificial Intelligence and Multiagent Systems） on the other side. Typical computational problems studied in this field include the vulnerability of voting procedures against attacks, or preference aggregation in multi-agent systems. Parameterized Algorithmics is a subfield of Theoretical computer science seeking to exploit meaningful problem-specific parameters in order to identify tractable special cases of in general computationally hard problems. In this paper, we propose nine of our favorite research challenges concerning the parameterized complexity of problems appearing in this context. This work is dedicated to Jianer Chen, one of the strongest problem solvers in the history of parameterized algorithmics,on the occasion of his 60 th birthday.
