In this paper we present FeynRules, a new Mathematica package that facilitates the implementation of new particle physics models. After the user implements the basic model information (e.g. particle content, parameters and Lagrangian), FeynRules derives the Feynman rules and stores them in a generic form suitable for translation to any Feynman diagram calculation program. The model can then be ...
FeynRules is a Mathematica-based package which addresses the implementation of particle physics models, which are given in the form of a list of fields, parameters and a Lagrangian, into high-energy physics tools. It calculates the underlying Feynman rules and outputs them to a form appropriate for various programs such as CalcHep, FeynArts, MadGraph, Sherpa and Whizard. Since the original vers...
In this work, we propose a multimodal interaction framework for robust human-multirobot communication in outdoor environments. In these scenarios, several human or environmental factors can cause errors, noise and wrong interpretations of the commands. The main goal of this work is to improve the robustness of human-robot interaction systems in similar situations. In particular, we propose a mu...
MCgrid is a software package that provides access to the APPLgrid interpolation tool for Monte Carlo event generator codes, allowing for fast and flexible variations of scales, coupling parameters and PDFs in cutting edge leadingandnext-to-leading-orderQCDcalculations. This is achievedbyproviding additional tools to the Rivet analysis system for the construction of MCgrid enhanced Rivet analyse...
Background and aims: human errors are of the most important causes of accidents in medical professions which impose exorbitant costs to the societies. Therefore, the present research was carried out in order to identify and evaluate human errors, using SHERPA technique, among physicians and nurses in emergency unit of one of the hospitals in Semnan. Method: In this qualitative and cross-section...
زمینه و هدف: علّت اکثر حوادث بزرگ دنیا خطای انسانی شناخته شده است. از این رو جهت کاهش خطاهای انسانی در ارزیابی و مدیریت ریسک نیاز جداگانهای به ارزیابی ریسک ناشی از خطای انسانی وجود دارد که این نیاز میتواند با استفاده از آنالیز قابلیت اطمینان انسانی تامین گردد. در صنعت بهداشت و درمان، هر ساله بیماران زیادی توسط خطاهای پزشکی جان خود را از دست میدهند. خطاهای درمانی مشکلی جهانی ...
Background and Aim: Today in many work environments, such as nuclear, military and chemical industries, human errors may result in disasters. Accidents in different parts of the world bear evidence to this examples are the Chernobyl disaster (1986), the Three Mile Island accident (1974), and the Flixborough explosion (1974). Thus, identification of human error, especially in complex and intrica...
We consider the problem of Bayesian inference in the family of probabilistic models implicitly defined by stochastic generative models of data. In scientific fields ranging from population biology to cosmology, low-level mechanistic components are composed to create complex generative models. These models lead to intractable likelihoods and are typically non-differentiable, which poses challeng...
We describe a framework to develop, implement and validate any perturbative Lagrangian-based particle physics model for further theoretical, phenomenological and experimental studies. The starting point is FeynRules, a Mathematica package that allows to generate Feynman rules for any Lagrangian and then, through dedicated interfaces, automatically pass the corresponding relevant information to ...
