Selected Problems of Sensitivity and Reliability of a Jack-Up Platform

Polish Maritime Research, 2018
The paper deals with sensitivity and reliability applications to numerical studies of an off-shore platform model. Structural parameters and sea conditions are referred to the Baltic jack-up drilling platform. The sudy aims at the influence of particular

SAR Image Invariant Feature Extraction by Anisotropic Diffusion and Multi-Gray Level Simplified PCNN

IEEE Access, 2019
Besides the target in synthetic aperture radar (SAR) image, the structural information remained in speckle and shadow is also very important when we extract the invariant feature of SAR image.

Full-length human cytomegalovirus terminase pUL89 adopts a two-domain structure specific for DNA packaging.

PLoS Pathogens, 2019
A key step in replication of human cytomegalovirus (HCMV) in the host cell is the generation and packaging of unit-length genomes into preformed capsids. The enzymes involved in this process are the terminases.

Invariants for Non-Hierarchical Object Structures

Electronic Notes in Theoretical Computer Science, 2008
AbstractWe present a Hoare-style specification and verification approach for invariants in sequential OO programs. It allows invariants over non-hierarchical object structures, in which update patterns that span several objects and methods occur frequently.

A Comprehensive Comparative Study of Quick Invariant Signature (QIS), Dynamic Time Warping (DTW), and Hybrid QIS + DTW for Time Series Analysis

Mathematics
This study presents a comprehensive evaluation of the quick invariant signature (QIS), dynamic time warping (DTW), and a novel hybrid QIS + DTW approach for time series analysis.

An invariant property of a structured population

Genetical Research, 1971
SUMMARYConsidering a single mutant gene in a geographically subdivided finite population, it is shown that the average number of heterozygotes, due to this gene, that appear in the population before fixation or loss of this gene is equal to twice the total population number. This is invariant under the geographical structure of the population.

Structural Invariants

This paper provides a principled account of why dimensionless invariants must arise in any admissible representation of a closure-first relational ontology. In the Coherence-Relational Blockworld (cRBW) framework, reality is identified with a single globally admissible relational structure, while representations introduce arbitrary descriptive elements

Geometric criticality in scale-invariant networks

Physical Review Research
Dimension in physical systems determines universal properties at criticality. Yet, the impact of structural perturbations on dimensionality remains largely unexplored.

Invariants of structures

We give a categorification of the notion of a mathematical structure originally given by Bourbaki in their set theory textbook. We show that any isomorphism-invariant property of a finite structure can be computed by counting the number of isomorphic copies of small substructures it contains.
