Propagation effects of model-calculated probability values in Bayesian networks [PDF]

open access: yes, 2015
Probabilistic causal interaction models have become quite popular among Bayesian-network engineers as elicitation of all probabilities required often proves the main bottleneck in building a real-world network with domain experts.

Terraform Sustainability Assessment Framework for Bioregenerative Life Support Systems

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In this perspective paper, we raise attention to the lack of methods or data to measure claims of sustainability for bioregenerative life support system designs and propose a method for quantifying sustainability.

Hybrid control systems [Elektronisk resurs]

open access: yes, 2004
Most practical control systems involve both analogue and logic components. Hybrid control system is a generic term for such systems, where the continuous and the discrete dynamics are interacting.

Wheat Space Odyssey: “From Seed to Seed”. Kernel Morphology

open access: yesLife, 2019
The long-term autonomous existence of man in extraterrestrial conditions is associated with the need to cultivate plants—the only affordable and effective means for both providing oxygen and CO2 utilization, and providing one of the most habitual ...

Cross-sectional use of barcode of life data system and GenBank as DNA barcoding databases for the advancement of museomics

open access: yesFrontiers in Ecology and Evolution, 2022
Museomics is an approach to the DNA sequencing of museum specimens that can generate both biodiversity and sequence information. In this study, we surveyed both the biodiversity information-based database BOLD (Barcode of Life System) and the sequence ...

Concise representations and construction algorithms for semi-graphoid independency models [PDF]

open access: yes, 2017
The conditional independencies from a joint probability distribution constitute a model which is closed under the semi-graphoid properties of independency. These models typically are exponentially large in size and cannot be feasibly enumerated.

Optimum conceptual design for the life support systems of manned spacecraft

open access: yesCogent Engineering, 2020
The problem of the optimal design of the life support systems of manned spacecraft is studied in this paper. The aim is to select components of all relevant subsystems to minimize the mass and power consumption and maximize the total technology readiness

Integrated Pest Management Protocols for Space-Based Bioregenerative Life Support Systems

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Human missions to the Moon and Mars will necessarily increase in both duration and complexity over the coming decades. In the past, short-term missions to low-Earth orbit (LEO) or the Moon (e.g., Apollo) utilized physiochemical life support systems for ...
