Bayesian Belief Network (BBN)-based advisory system development for steam generator replacement project management
… relevant experts, the Bayesian Belief Network (BBN) approach was selected to model the steam generator replacement proj ect management problem, where the situation holds inherently large uncertainty and complexities, since it has a superior ability to treat complexities, uncertainty management, …

Bayesian belief networks to integrate monitoring evidence of water distribution system contamination
A Bayesian belief network (BBN) methodology is proposed for combining evidence to better characterize contamination events and reduce false positive sensor detections in drinking water distribution systems. A BBN is developed that integrates sensor data with other validating evidence of …

UAS Risk Analysis using Bayesian Belief Networks: An Application to the VirginiaTech ESPAARO
… (FTA) method to a Bayesian Belief Network (BBN) model. FTA is demonstrated to be a special case of BBN and BBN can allow for more complex interactions between nodes than is allowed by FTA. A model can be investigated to determine the components to which failure is most sensitive and allow …

Primordial Nucleosynthesis in the New Age of Cosmology: Determining Uncertainties, Examining Concordance, and Probing New Physics
Big bang nucleosynthesis (BBN) has long played a key role in the standard cosmology. BBN accurately predicts the primordial light element abundances of deuterium, helium and lithium. The general concordance between the predicted and observed light element abundances provides a direct probe of the …

An expert-based Bayesian investigation of greenhouse gas emission reduction options for German passenger vehicles until 2030
… of twelve central variables within the BBN - battery energy, fuel and electricity consumption, relative costs, and sales shares of the vehicle types - have been quantified by experts from German car manufacturers in a second series of interviews. For each of the seven second-round …

Indirect 2H(d,p)3H and 2H(d,n)3He fusion reactions measurement at energies relevant for Big Bang Nucleosynthesis
… and 2H(d,n)3He in the Big Bang Nucleosynthesis (BBN) astrophysical scenario. In the beginning is presented this phase of the early universe and why the BBN model is still fine tuned with new results coming from observations and laboratory measurements. This model (if BBN is considered standard) …

Advanced monitoring and advice integrating a comprehensive sensor network for improved operational availability
… system employs a Bayesian Belief Network (BBN) as a high level reasoning tool for incorporating inherent uncertainty for use in probabilistic inference. It is demonstrated that a rule-based knowledge representation is simply a special case of a general BBN by showing how the general BBN can …

Assisting minority micro-entrepreneurship : evaluation of a proposed model for Brazilians in Massachusetts
… proposed plan by the Brazilian Business Network (BBN) is then critiqued. BBN was found to have many strengths, and the basis for its plan was sound, but the plan itself needed substantial development. The final recommendations include: further specific research on the target population to confirm …

Development of Failure and Consequence Analysis Frameworks for Natural Gas Transmission Pipeline
… Modeling (ISM) and Bayesian Belief Network (BBN) are integrated to analyze the failure causes and influences of natural gas transmission pipeline. After that, to identify the consequence of the natural gas transmission pipeline failure, the potential threat zone simulation is performed using …

Targeting the bombesin subtype 2 receptor for the diagnosis and treatment of metastatic prostate cancer
… with high affinity to the bombesin peptide (BBN), stimulating agonist mediated receptor-peptide internalization into the cancer cell. Accordingly, targeting the BB2r with radioisotopes conjugated to BBN represents a promising method for diagnostic and therapeutic radiopharmaceutical …

Synthesis of Single Isomer Trisubstituted Olefins from beta-chloro-alpha-iodo-alpha, beta-Unsaturated Esters and Alkynyl Esters
… esters cross-couple with 9-alkyl-9-BBN to produce single isomer trisubstituted olefins using palladium-catalyzed Suzuki-Miyaura cross-coupling reaction. This methodology can be further expanded to introduce various alkyl groups at the beta-position. The mechanism is somewhat unusual …

Synthesis of New Alkyn-1-ylsilanes. 1,1-Organoboration, 1,2-Hydroboration
… prepared by reacting dialkyn-1-ylsilanes with 9-BBN at 353-373 K. In a first step, alkenyl(alkyn-1-yl)silanes are formed as a result of intermolecular 1,2-hydroboration followed by intramolecular 1,1-vinylboration at the same temperature to afford 1-silacyclobutene derivatives. The first …
