Reducing simulator sickness with perceptual camera control

Hu, Ping ; Sun, Qi ; Didyk, Piotr ; Wei, Li-Yi ; Kaufman, Arie E.

In: ACM transactions on graphics, 2020, vol. 38, no. 6, p. 15 p

Virtual-reality provides an immersive environment but can induce cybersickness due to the discrepancy between visual and vestibular cues. To avoid this problem, the movement of the virtual camera needs to match the motion of the user in the real world. Unfortunately, this is usually difficult due to the mismatch between the size of the virtual environments and the space available to the users...

3D models related to the publication: New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of the early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: MorphoMuseuM, 2020, vol. 6, no. 3, p. e116

The present 3D Dataset contains two 3D models described in Tissier et al. ( the only known complete mandible of the early-branching rhinocerotoid Epiaceratherium magnum Uhlig, 1999, and a hypothetical reconstruction of the complete archetypic skull of Epiaceratherium Heissig, 1969, created by merging three cranial parts from three distinct Epiaceratherium...

Cranial osteology of the early cretaceous turtle Pleurosternon bullockii (paracryptodira: pleurosternidae)

Evers, Serjoscha W. ; Rollot, Yann ; Joyce, Walter G.

In: PeerJ, 2020, vol. 8, p. e9454

Pleurosternon bullockii is a turtle from the Early Cretaceous of Europe known from numerous postcranial remains. Only one skull has so far been referred to the species. Pleurosternon bullockii belongs to a group of turtles called pleurosternids, which is thought to include several poorly known taxa from the Late Jurassic and Early Cretaceous of Europe and North America. Pleurosternids and...

FJProf : profiling fork/join applications on the Java virtual machine

Rosales, Eduardo ; Rosà, Andrea ; Binder, Walter

An efficient fork/join application should maximize parallelism while minimizing overheads, and maximize locality while minimizing contention. However, there is no unique optimal implementation that best resolves such tradeoffs and failing in balancing them may lead to fork/join applications suffering from several issues (e.g., suboptimal forking, load imbalance, excessive synchronization),...

Analysis and optimization of task granularity on the Java virtual machine

Rosà, Andrea ; Binder, Walter (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO008.

Task granularity, i.e., the amount of work performed by parallel tasks, is a key performance attribute of parallel applications. On the one hand, fine-grained tasks (i.e., small tasks carrying out few computations) may introduce considerable parallelization overheads. On the other hand, coarse-grained tasks (i.e., large tasks performing substantial computations) may not fully utilize the...

A description of the skull of eubaena cephalica (hay, 1904) and new insights into the cranial circulation and innervation of baenid turtles

Rollot, Yann ; Lyson, Tyler R. ; Joyce, Walter G.

In: Journal of Vertebrate Paleontology, 2018, vol. 38, no. 3, p. e1474886

The internal carotid system has played an important role in the systematics of fossil turtles, including baenids. A new, almost perfectly preserved specimen of Eubaena cephalica provides an opportunity to explore for the first time the cranial circulation and innervation of this taxon using CT (computed tomography) scans. We here document that the skull possesses a well-developed, branching...
