While the commonly applied effort measure is based on analyst behaviour for one firm, our measure considers analyst behaviour for all covered firms. Our general effort measure captures additional information about analyst effort and thus can identify accurate forecasts. We emphasise the importance of investigating analyst behaviour in a larger context and argue that analysts who generally devote substantial forecast effort are also likely to devote substantial effort to a specific firm, even if this effort might not be captured by a firm-specific measure. Empirical results reveal that analysts who devote higher general forecast effort issue more accurate forecasts. Additional investigations show that analysts' career prospects improve with higher general forecast effort. Our measure improves on existing methods as it has higher explanatory power regarding differences in forecast accuracy than the commonly applied effort measure. Additionally, it can address research questions that cannot be examined with a firm-specific measure. It provides a simple but comprehensive way to identify accurate analysts.}, language = {en} } @article{KleinesZiemonsZwoll1998, author = {Kleines, H. and Ziemons, Karl and Zwoll, K.}, title = {Experiences with ATM in a multivendor pilot system at Forschungszentrum J{\"u}lich}, series = {IEEE Transactions on Nuclear Science}, volume = {45}, journal = {IEEE Transactions on Nuclear Science}, number = {4}, issn = {0018-9499}, pages = {1867 -- 1871}, year = {1998}, abstract = {The ATM technology for high speed serial transmission provides a new quality of communication by introducing novel features in a LAN environment, especially support of real time communication, of both LAN and WAN communication and of multimedia streams.

Its discretization via the boundary element collocation method in combination with the algorithm by Beyn yields highly accurate results both for the first non-zero eigenvalue and its corresponding eigenfunction which is due to superconvergence. Additionally, it can be shown numerically that the ratio between the maximal/minimal value inside the domain and its maximal/minimal value on the boundary can be larger than 1 + 10- 3.

A large image repository is obtained from about 50,000 m sewers to represent the high variability of real world sewer systems. Automatic image processing combines Canny edge detection, Hough transform for straight lines and cost minimization using Dijkstra's shortest path algorithm. Assuming that flow lines are mostly smoothly connected horizontal structures, piecewise flow line delineation is reduced to a process of selecting adjacent line candidates. Costs are derived from the gap between adjacent candidates and their reliability. A single parameter α enables simple control of the algorithm. The detected flow line may precisely follow the segmented edges (α = 0.0) or minimize gaps at joints (α = 1.0). Both, manual and ground truth-based analysis indicate that α = 0.8 is optimal and independent of the sewer's material. The algorithm forms an essential step to further automation of sewer inspection.}, language = {en} } @inproceedings{KirschMatareFerreinetal.2020, author = {Kirsch, Maximilian and Matar{\´e}, Victor and Ferrein, Alexander and Schiffer, Stefan}, title = {Integrating golog++ and ROS for Practical and Portable High-level Control}, series = {Proceedings of the 12th International Conference on Agents and Artificial Intelligence - Volume 2}, booktitle = {Proceedings of the 12th International Conference on Agents and Artificial Intelligence - Volume 2}, publisher = {SciTePress}, address = {Set{\´u}bal, Portugal}, doi = {10.5220/0008984406920699}, pages = {692 -- 699}, year = {2020}, abstract = {The field of Cognitive Robotics aims at intelligent decision making of autonomous robots. It has matured over the last 25 or so years quite a bit. That is, a number of high-level control languages and architectures have emerged from the field. One concern in this regard is the action language GOLOG. GOLOG has been used in a rather large number of applications as a high-level control language ranging from intelligent service robots to soccer robots. For the lower level robot software, the Robot Operating System (ROS) has been around for more than a decade now and it has developed into the standard middleware for robot applications. ROS provides a large number of packages for standard tasks in robotics like localisation, navigation, and object recognition. Interestingly enough, only little work within ROS has gone into the high-level control of robots. In this paper, we describe our approach to marry the GOLOG action language with ROS. In particular, we present our architecture on inte grating golog++, which is based on the GOLOG dialect Readylog, with the Robot Operating System. With an example application on the Pepper service robot, we show how primitive actions can be easily mapped to the ROS ActionLib framework and present our control architecture in detail.}, language = {en} } @inproceedings{KirschMarcher2010, author = {Kirsch, Ansgar and Marcher, Thomas}, title = {Numerical prediction of time-dependent rock swelling based on an example of a major tunnel project in Ontario/Canada}, series = {Numerical methods in geotechnical engineering : (NUMGE 2010) : proceedings of the seventh European Conference on Numerical Methods in Geotechnical Engineering, Trondheim, Norway, 2 - 4 June 2010 / ed. by Thomas Benz ...}, booktitle = {Numerical methods in geotechnical engineering : (NUMGE 2010) : proceedings of the seventh European Conference on Numerical Methods in Geotechnical Engineering, Trondheim, Norway, 2 - 4 June 2010 / ed. by Thomas Benz ...}, publisher = {Taylor and Francis}, address = {London}, organization = {European Conference on Numerical Methods in Geotechnical Engineering <7, 2010, Trondheim>}, isbn = {978-0-415-59239-0}, pages = {297 -- 302}, year = {2010}, language = {en} } @inproceedings{KirschFelberMarcheretal.2014, author = {Kirsch, Ansgar and Felber, W. and Marcher, Thomas and Fuchs, W.}, title = {Geotechnical challenges during design and construction of a ski resort in Azerbaijan}, series = {Geotechnics of roads and railways : proceedings of the 15th Danube - European Conference on Geotechnical Engineering : 9-11 September 2014, Vienna, Austria}, booktitle = {Geotechnics of roads and railways : proceedings of the 15th Danube - European Conference on Geotechnical Engineering : 9-11 September 2014, Vienna, Austria}, publisher = {{\"O}IAV - {\"O}sterreichischer Ingenieur- und Architekten-Verein}, address = {Wien}, organization = {Danube - European Conference on Geotechnical Engineering <15, 2014, Wien>}, isbn = {978-3-902593-01-6}, pages = {757 -- 762}, year = {2014}, language = {en} }
