We evaluate the stellar energy-loss rates [Formula: see text] due to production of neutrino pair in 3-3-1 models. The energy loss rate is evaluated for different values which a parameter used define charge operator 331 show that contribution dipole moment small compared new natural gauge boson text]. correction with Standard Model and do not exceed 14% highest Of all models, model give relative...
The main purpose of this study is to identify the determinants of banking crisis loss, the variables of policy framework especially, for 12 sample countries over the period 1980-2019. Accordingly, we extracted pre-crisis and post-crisis trends from countries' real GDPs and then calculated output loss for the crisis year and three years afterwards. In the following, we used the Poisson quasi-max...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
abstract optimal management of water and nutrient could consider as effective on farm method to reduce pollution because agriculture is none point pollution. in this research, an optimal model was presented to reduce nitrate loss in furrow fertigation. the optimal model contains four simulation models for predicting runoff, deep percolation, nitrate concentration in runoff and nitrate concentra...
risk management is one of the most important aspects of project management that identifies, assesses and responds to project risks. although many papers have been published in project risk response, presented tools and methods are poor. hence, in this paper, we present an optimization model to respond project risk that seeks to optimize two key criteria of project: cost and time. the proposed m...
many factors affect yield loss in wheat harvesting with a grain combine harvester and there is no mathematical model to describe the behavior of this complex system. thus in this study, a fuzzy logic controller (flc) was designed, implemented and tested for the automatic settings of cylinder speed, concave clearance, fan speed and forward speed of a model 955 john deere combine. first, the mech...
