The CogALex-V Shared Task on the Corpus-Based Identification of Semantic Relations
No full textThe shared task of the 5th Workshop on Cognitive Aspects of the Lexicon (CogALex-V) aims
at providing a common benchmark for testing current corpus-based methods for the identifica-
tion of lexical semantic relations (
synonymy
,
antonymy
,
hypernymy
,
part-whole meronymy
) and
at gaining a better understanding of their respective strengths and weaknesses. The shared task
uses a challenging dataset extracted from EVALution 1.0 (Santus et al., 2015b), which contains
word pairs holding the above-mentioned relations as well as semantically unrelated control items
(
random
). The task is split into two subtasks: (i) identification of related word pairs vs. unre-
lated ones; (ii) classification of the word pairs according to their semantic relation. This paper
describes the subtasks, the dataset, the evaluation metrics, the seven participating systems and
their results. The best performing system in subtask 1 is GHHH (

Inverse determination of the fatigue Strain Energy Density control radius for conventionally and additively manufactured rounded V-notches
No full textThe Strain Energy Density (SED) fatigue criterion is based on a material control radius. The value of this length is therefore required for an accurate assessment of the fatigue strength of any, especially severely, notched components. The singularity-based control radius is initially obtained by considering the hypothetical perfectly sharp V-notched specimen. The effect of the notch radius on the inverse search is then investigated with numerical simulations, and a new analytical procedure is introduced for the determination of the (actual) control radius. This procedure is applied to the experimental data of three metal alloys with different load ratios and manufacturing conditions
Proposal for Tip Relief Modification to reduce Noise in Spur Gears and sensitivity to meshing conditions
No full textIn the paper a new Tip Relief Profile Modification for spur Gears is presented. The topography here proposed is a classical linear profile modification with a parabolic fillet (Linear- Parabolic modification).
The parabolic fillet extension is treated as a parameter and its effect investigated.
The proposed topography is able to take advantages from both Linear, and Parabolic tip relief. The evolution from Linear to Parabolic is discussed in terms of Peak to Peak Transmission Error. Anomalous contact conditions due to particular tip relief modification are reported, and maps are obtained in order to find optimum tip relief by taking into account contact conditions boundaries too
A method to define profile modification of spur gear and minimize the transmission error

The topography proposed here is a classical linear profile modification with a parabolic fillet (linear-parabolic modification). The parabolic fillet extension is treated as a parameter and its effect investigated.
The proposed topography combines advantages from both linear and parabolic tip relief. The evolution from linear to parabolic is discussed in terms of peak-to-peak transmission error. Anomalous contact conditions due to particular tip relief modifications are reported,and maps are obtained in order to find optimum tip relief by taking into account contact condition boundaries
