On the Use of Underspecified Data-Type Semantics for Type Safety in Low-Level Code

open access: yes, 2012
In recent projects on operating-system verification, C and C++ data types are often formalized using a semantics that does not fully specify the precise byte encoding of objects.

Instantaneous identification of Bouc-Wen-type hysteretic systems from seismic response data [PDF]

open access: yes, 2007
This paper presents a technique for identification of non-linear hysteretic systems subjected to non-stationary loading. In the numerical simulations, a Bouc-Wen model was chosen for its ability to represent the properties of a wide class of real ...

AlgaTerra Information System: Types data and data types [PDF]

open access: yesProceedings of the 1st Central European Diatom Meeting 2007, 2007
AlgaTerra is an information system for micro algal biodiversity (Jahn & Kusber 2007) which has been online since 2004. The database is a concept based implementation of the Berlin Model, developed at the BGBM, Berlin. The basic data have been researched within a joint project of five German research groups between 2001 and 2005 (R.

Improving Automatic Content Type Identification from a Data Set [PDF]

open access: yes, 2017
Data file layout inference refers to building the structure and determining the metadata of a text file. The text files dealt within this research are personal information records that have a consistent structure. Traditionally, if the layout structure

MissForest - nonparametric missing value imputation for mixed-type data

open access: yes, 2011
Modern data acquisition based on high-throughput technology is often facing the problem of missing data. Algorithms commonly used in the analysis of such large-scale data often depend on a complete set.

A Type Language for Calendars [PDF]

open access: yes, 2005
Time and calendars play an important role in databases, on the Semantic Web, as well as in mobile computing. Temporal data and calendars require (specific) modeling and processing tools.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

An inverse problem of Calderon type with partial data [PDF]

open access: yes, 2011
A generalized variant of the Calder\'on problem from electrical impedance tomography with partial data for anisotropic Lipschitz conductivities is considered in an arbitrary space dimension $n \geq 2$.

WFPC2 Images of the Central Regions of Early-Type Galaxies - I. The Data [PDF]

open access: yes, 2001
We present high resolution R-band images of the central regions of 67 early-type galaxies obtained with the Wide Field and Planetary Camera 2 (WFPC2) aboard the Hubble Space Telescope (HST).

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
