DESCRIPTION OF \u3ci\u3eHAKKA\u3c/i\u3e, A NEW GENUS OF JUMPING SPIDER (ARANEAE, SALTICIDAE) FROM HAWAII AND EAST ASIA [PDF]

open access: yes, 2001
We describe a new genus for a jumping spider that was originally placed in the large genus Menemerus Simon 1868, from which the new genus is clearly different. They were later reclassified as Icius, then as Pseudicius, and still later as Salticus.

Reconfiguring Independent Sets in Claw-Free Graphs [PDF]

open access: yes, 2014
We present a polynomial-time algorithm that, given two independent sets in a claw-free graph $G$, decides whether one can be transformed into the other by a sequence of elementary steps.

Analysis of Landing in Ski Jumping by Means of Inertial Sensors and Force Insoles

open access: yesProceedings, 2018
Landing and its preparation are important phases for performance and safety of ski jumpers. A correct ski positioning could influence the jump length as also the cushioning effect of the aerodynamic forces that permits the reduction of landing impacts ...

xLength: Predicting Expected Ski Jump Length Shortly after Take-Off Using Deep Learning

open access: yesSensors, 2022
With tracking systems becoming more widespread in sports research and regular training and competitions, more data are available for sports analytics and performance prediction. We analyzed 2523 ski jumps from 205 athletes on five venues. For every jump,

A leap into the future: Towards an augmented reality learning environment in ski-jumping

open access: yesCurrent Issues in Sport Science
Introduction Professional sports are fiercely competitive. In ski jumping, for example, even small changes in take-off and flight can make a decisive difference between victory and defeat (Elfmark et al., 2022).
