In the twenty-first century, cities face a lot of turmoil. The City Prosperity model, presented by United Nations Human Settlements Program (UN-Habitat) in 2012, offers a new approach to urban flourishing and sustainability, and it is looking for a fundamental solution to improve the quality of life. This article focuses on measuring the quality of life in the Narmak neighborhood of Tehran bas...
One of the most widely used propellants is nitrocellulose (NC) based on propellant, which is divided into three general groups including single base propellant (SBP), double base propellant (DBP), and triple base propellant (TBP). In this paper, the life time of three types of NC-based propellants has been examined by using the vacuum stability test (VST). In this method, kinetic equations have...
Background: Nurses are responsible for maintaining and improving the health and quality of life of patients. Therefore, it is important to assess the quality of life of nurses in order to improve it. Quality of life is affected by many variables and among them burnout, perceived social support and psychological hardiness are the leading ones. This study aimed at predicting the quality of ...
artificial neural network is one of the most robust and reliable methods in online prediction of nonlinear incidents in machining. tool flank wear as a tool life criterion is an important task which is needed to be predicted during machining processes to establish an online tool life estimation system. in this study, an artificial neural network model was developed to predict the tool wear and ...
this study tries to codify a proper mathematical model which can be predict the costs of repair and maintaining the tractors as precisely as possible for three common models of tractors in shahid beheshti cultivation firm in andimeshk-ahvaz road of dezfoul. studied tractors include: newhland tm155 tractor which is chosen from the most perfect file of 10 tractor machines and jandier tractor-3140...

Abstract: Interest rate is assumed for the constant in some insurance references. They include the calculation of spouse allied scheme insurance premium and reserve and calculation of family combined insurance premium under the constant interest rate.Interest randomness in life insurance has received considerable attention in recent literatures on actuarial theory and its applications. In order...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
