abstract: in this study an appropriate computational approach was presented for estimating the boiling temperatures of 41 different types of olefins and their derivatives. based on the guidelines of this approach, several structural indices related to the organic components were applied using graph theory. meanwhile, in addition to evaluating the relation between the boiling temperatures of ole...

In a multiple linear regression model, there are instances where one has to update the regression parameters. In such models as new data become available, by adding one row to the design matrix, the least-squares estimates for the parameters must be updated to reflect the impact of the new data. We will modify two existing methods of calculating regression coefficients in multiple linear regres...

In this study a new and robust procedure is presented to solve synthesis of isothermal reactor networks (RNs) which considers more than one objective function. This <span style="font-size: 9pt; color: #0...

The new wave of COVID-19 in Hong Kong, China was overwhelming again by “dynamic zero” strategy and non-pharmaceutical interventions (DZ-NPIs), which makes a time challenge to control the variant this epidemic. We describe Covid-19 Kong infected proportion population, cumulative confirmed cases, deaths current hospitalizations age group via statistical measure firstly, then establish series mode...

Driver safety priority is among the factors that affect sleepy driving behavior of truck drivers. The aim this paper to determine effect drivers' driver on with linear and non-linear models. Two hypotheses have been developed within scope research. sample area consists 399 Turkish Surveys were collected face online between January 2022 April 2022. has determined by simple random method. "Driver...
