Análise espacial e de vizinhança no melhoramento genético de plantas Neighborhood and spatial analysis in plant breeding

Pesquisa Agropecuária Brasileira, 2005
Três formas de análise espacial foram comparadas à análise do modelo linear Gauss-Markov normal em experimentos de Genética, tendo-se suposto os efeitos de progênies como aleatórios: médias móveis nos dados brutos (MM), médias móveis nos dados residuais (

A Maintenance Cost Study of Transformers Based on Markov Model Utilizing Frequency of Transition Approach

Energies, 2018
In this paper, a maintenance cost study of transformers based on the Markov Model (MM) utilizing the Health Index (HI) is presented. In total, 120 distribution transformers of oil type (33/11 kV and 30 MVA) are examined.

Range of 21st century ice mass changes in the Filchner-Ronne region of Antarctica

Journal of Glaciology, 2023
Increases in ocean temperatures in the Filchner Ronne region of Antarctica are likely to result in increased ice mass loss and sea level rise. We constrain projections of the 21st century sea level contribution of this region using process-based ice ...

Application of Markov Model to Estimate Individual Condition Parameters for Transformers

Energies, 2018
This paper presents a study to estimate individual condition parameters of the transformer population based on Markov Model (MM). The condition parameters under study were hydrogen (H2), methane (CH4), acetylene (C2H2), ethylene (C2H4), ethane (C2H6 ...

Automatic and Accurate Measurement of High Precision Thread Based on AA R2Unet and HMM

Nantong Daxue xuebao. Ziran kexue ban, 2021
The thread measurement methods based on machine vision are easily disturbed by the environment(e.g. dust,iron filings, oil stains, etc.), resulting in inaccurate measurement results. This paper improves the R2 Unet model by adding the Attention mechanism,

Comparisons of wave dynamics in Hodgkin-Huxley and Markov-state formalisms for the sodium (Na) channel in some mathematical models for human cardiac tissue

Physical Review Research, 2020
We compare and contrast the excitation properties of cardiac myocytes and cardiac tissue modeled by (a) a Hodgkin-Huxley-model (HHM) and (b) Markov-chain-model (MM) formalisms for the sodium (Na) ion channel.
