We present the implementation and validation of the techniques used to efficiently evaluate parametric and perturbative theoretical uncertainties in matrix-element plus parton-shower simulations within the Sherpa eventgenerator framework. By tracing the full αs and PDF dependences, including the parton-shower component, as well as the fixed-order scale uncertainties, we compute variational even...
Free access to the articles is becoming more popular since it gives thousands of researchers access to millions of publications resulting in higher visibility and receiving much more citations, which often times might be the ultimate goal. For this reason, authors may seek a way to make the papers easily accessible to other researchers via uploading the full text to their personal website and/o...
Numerical optimization of an inverted-bow trimaran is carried out through three simulation-based design (SBD) frameworks. Different positions the trimaran’s side hull are investigated based on a computational fluid dynamics solver using non-dominated sorting genetic algorithm-III (NSGA-III), simultaneous hybrid exploration that robust, progressive and adaptive (SHERPA) response surface (RS) mul...
The Himalayan Sherpas, a human population of Tibetan descent, are highly adapted to life in the hypobaric hypoxia of high altitude. Mechanisms involving enhanced tissue oxygen delivery in comparison to Lowlander populations have been postulated to play a role in such adaptation. Whether differences in tissue oxygen utilization (i.e., metabolic adaptation) underpin this adaptation is not known, ...
Some results highlighting the status of a new version of a cluster fragmentation model for the Monte Carlo event generator Sherpa are presented. In its present version this model is capable of simulating e + e − annihilation events into light-quark and gluon jets. We compare results for different multiplicity and momentum distributions to available SLD and LEP data as well as to results obtaine...
زمینه و هدف : خطاهای انسانی نقش قابل ملاحظه ای را در بروز حوادث صنعتی دارند. یکی از عملیات های مهم مستعد خطای انسانی در معادن، عملیات آتش باری می باشد. به همین منظور هدف از این مطالعه شناسایی و ارزیابی ریسک خطاهای انسانی درعملیات آتش باری یک معدن سنگ آهن می باشد. روش بررسی : مطالعه ی حاضر، مطالعه مورد پژوهی از نوع پژوهش کیفی می باشد که به منظور شناسایی و ارزیابی خطای انسانی شغل آتش باری در یک...
I discuss the use of quantitative, qualitative, and collaborative methods to document and operationalize Indigenous ecological knowledge, using case studies from the Nepalese Himalaya and Great Basin. Both case studies applied results to natural and cultural resource management and interpretation for the public. These approaches attempt to reposition the interview subjects to serve as active co...
