Abstract: An SEIR epidemic model is investigated to ascertain the impact of exposed individuals at latent period (individuals who are infected but not yet infectious) on the transmission dynamics of measles. Mathematical analysis is carried out that completely determine the dynamics of the model. The impact of exposed individuals at latent period are discussed through the stability analysis and...
Background and Aims: Recognition and prevention of burnout an important role in promoting mental health and increasing the quality of services provided. This paper aims to prevent the occurrence of this problem, seeking to identify the effective factors on the burnout. Methods: Many studies have been carried out by researchers on staff burnout using a descriptive-analytical approach, but a m...
With the introduction of any given variable in random dynamic general equilibrium models, the behavioral functions of economic agents will change, and consequently the shocks to the economy show a different direction and response. One of the most important sectors in the dynamics of a countrychr('39')s economy is the housing sector and one of the main determinants of the stagnation and boom of ...
Despite the presence of 90% of double-fuel taxis (gasoline + CNG) in the urban taxi fleet, fuel consumption choices are more dependent on pricing policies and factors such as gasoline subsidies and quotas, and with the slightest change in fuel rates and quotas, use natural gas fuel. . Impact and challenge fuel management in the public transport fleet. The main purpose of this is to identify way...
This work is concerned with the analysis of vibro-impact responses observed in large-scale nonlinear geared systems. Emphasis laid on interactions between high-frequency internal excitation generated by meshing process, i.e. static transmission error and time-varying mesh stiffness, low-frequency external excitations. To this end, a three-dimensional finite element model pump equipped reverse s...
