Reconstructing PASCAL VOC [PDF]

2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
We address the problem of populating object category detection datasets with dense, per-object 3D reconstructions, bootstrapped from class labels, ground truth figure-ground segmentations and a small set of keypoint annotations. Our proposed algorithm first estimates camera viewpoint using rigid structure-from-motion, then reconstructs object shapes by

Open-Circuit Voltage (VOC) Enhancement in TiO2-Based DSSCs: Incorporation of ZnO Nanoflowers and Au Nanoparticles

ACS Omega, 2020
An important reason for the relatively low efficiency of dye-sensitized solar cells (DSSCs) is the low open-circuit voltage (VOC) of about 0.7 V for a standard solar cell with a dye that has an absorption onset at 1.6 eV.

The purpose shapes the vocative: Prosodic realisation of Colombian Spanish vocatives [PDF]

Journal of the International Phonetic Association, 2018
The question of whether intonation contours directly signal meaning is an old one. We revisit this question using vocatives in Colombian Spanish (Bogotá). We recorded speakers' productions in three pragmatic conditions – greeting, confirmation-seeking, and reprimand – and compared proper names (vocatives) to situation-specific one-word utterances, such

Tracking Short-Range Attraction and Oviposition of European Grapevine Moths Affected by Volatile Organic Compounds in a Four-Chamber Olfactometer

Insects, 2020
The identification of volatile organic compounds (VOCs) leading to short-range attraction and oviposition of the European grapevine moth Lobesia botrana and European grape berry moth Eupoecilia ambiguella (Lepidoptera: Tortricidae) is crucial in order to
