In this paper, at first, we introduce $alpha_{mu}$-admissible, $Z_mu$-contraction and  $N_{mu}$-contraction via simulation functions. We prove some new fixed point theorems for defined class of contractions   via $alpha$-admissible simulation mappings, as well. Our results  can be viewed as extension of the corresponding results in this area.  Moreover, some examples and an application to funct...

application of agent based model in simulation of stakeholder’s behavior is slightly a new method for modeling of complicated systems that include autonomous agents interacting with each other. recent numerical achievements have made the applications of agent based models possible in various fields. these applications range from modeling of human progress and destruction of past civilizations t...

background: the aim of this study is to develop a new ergonomics chisel based on user centered design approach and to evaluate the effectiveness for reducing awkward posture using catia software for simulation analysis. methods: respondents were selected using purposive sampling – age 18 – 49 years old, men, experience using chisel (>1 month). a set of questionnaire were used to interview worke...

   Self-heating leads to a temperature rise of the laser diode and limits the output power and efficiency due to increased loss and decreased differential gain. To control device self-heating, it is required to design the laser structure with a low optical loss, while the heat flux must spread out of the device efficiently. In this study, a new asymmetric waveguide design is proposed and th...

in order to estimate doa of coherent sources, shirvani moghaddam and keshavarz nasab proposed a method based on uniform linear array configuration that first determines the number of noncoherent sources and then estimates the doa of coherent signals in each group. for estimating doas close to the array endfire, ula does not perform well. as the main goal of this investigation, using the propose...

due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. this paper employs modified petri nets (mpn) to model theses subsystems and makes it simple to analyze them. in this method, first, the continuous transfer function is converted to a discrete transfer function and then, by mpn, system is modeled and analyzed. all...
