The experiment of integrated mobile technologies used for deep hydrocarbon accumulation prospecting and geophysical mapping at the West Antarctic bottom structures

open access: yesГеофизический журнал, 2017
The data obtained confirm earlier assumption about possible existence of large accumulations of oil and gas hydrates in this part of the West Antarctica. Their formation in the structures of passive continental margin of the Antarctic Peninsula occurred

Stratigraphic Model of East Biak Based on Magnetotelluric Data

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
Biak Island is thought to have originated from the Australian Continental passive margin in the Mesozoic. This passive margin underwent tectonic collision to form the bedrock of Biak Island during the Paleogene.

Temperature characterisation of an optically-interrogated Rogowski coil [PDF]

open access: yes, 2014
An investigation into the performance of an optically-interrogated Rogowski coil over temperatures up to 80 °C is presented. Preliminary thermal tests reveal that the sensor response is temperature-dependent and the measurement errors are increased at ...

Active Nearest-Neighbor Learning in Metric Spaces

open access: yes, 2017
We propose a pool-based non-parametric active learning algorithm for general metric spaces, called MArgin Regularized Metric Active Nearest Neighbor (MARMANN), which outputs a nearest-neighbor classifier.

Active classification with comparison queries

open access: yes, 2017
We study an extension of active learning in which the learning algorithm may ask the annotator to compare the distances of two examples from the boundary of their label-class. For example, in a recommendation system application (say for restaurants), the

CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY OF THE S’ADDE LIMESTONE (MT. ALBO, OROSEI GULF): INSIGHTS INTO THE MIDDLE-LATE JURASSIC EASTERN SARDINIA PASSIVE MARGIN EVOLUTION

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2012
Calcareous nannofossil biostratigraphy has been performed on tree sections cropping out in Eastern Sardinia (Orosei Gulf, Mt. Albo). Calcareous nannofossils are rare to few and poorly to moderately preserved.

Insight private equity : [Version 18 June 2013] [PDF]

open access: yes, 2013
We are able to shed light on the black box of restructuring tools private equity investors use to improve the operational performance of their portfolio companies. By building on previous work considering performance evaluation of PE backed companies, we

Noise-adaptive Margin-based Active Learning and Lower Bounds under Tsybakov Noise Condition [PDF]

open access: yes, 2015
We present a simple noise-robust margin-based active learning algorithm to find homogeneous (passing the origin) linear separators and analyze its error convergence when labels are corrupted by noise.

Adaptivity to Noise Parameters in Nonparametric Active Learning

open access: yes, 2017
This work addresses various open questions in the theory of active learning for nonparametric classification. Our contributions are both statistical and algorithmic: -We establish new minimax-rates for active learning under common \textit{noise ...

Passive margins through earth history [PDF]

open access: yesEarth-Science Reviews, 2008
Abstract Passive margins have existed somewhere on Earth almost continually since 2740 Ma. They were abundant at 1900–1890, 610–520, and 150–0 Ma, scarce at ca. 2445–2300, 1600–1000, and 300–275 Ma, and absent before ca. 3000 Ma and at 1740–1600. The fluctuations in abundance of passive margins track the first-order fluctuations of the independently ...
