A simple mathematical model of the scientific peer reviewing process is developed. Papers and reviewers are modeled as numerical vectors, respectively representing paper’s value among multiple quality dimensions, importance given to these dimensions by a reviewer. Computer simulations show that can reproduce various characteristics real-world paper decision process, in particular its propensity...

Whereas computer simulations involve no direct physical interaction between the machine they are run on and the physical systems they are used to investigate, they are often used as experiments and yield data about these systems. It is commonly argued that they do so because they are implemented on physical machines. We claim that physicality is not necessary for their representational and pred...

Computer modelling for evolutionary systems consists in: 1) to store in the memory the individual features of each member of a large population; and 2) to update the whole system repeatedly, as time goes by, according to some prescribed rules (reproduction, death, ageing, etc) where some degree of randomness is included through pseudo-random number sequences. Compared to direct observation of N...

The inconsistencies accompanied with material properties tipically cause the rise of delamination risk in composites made of different types of glass and crabon fibers. In this study, the delamination of a composite beam reinforced with a carbon layer under bending load is investigated. To this end, a small piece of a wind turbine blade root in the form of a heterogeneous laminated plate is sim...

The Rab1-Nielsen formulas are used to make predictions for solar pond operations for four locations situated in different solar insulation zones in Iran. The inputs to the computer program for determining the temperature variation at the bottom of the pond are the total insulation (corrected for cloudiness). ambient temperature, insolating layer thickness, convection layer thickness and load. T...

Enhanced oil recovery using nitrogen injection is a commonly applied method for pressure maintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction of a reservoir performance in the course of injection process; however, a detailed simulation might take up enormous computer processing time. In such cases, a simple statistical model may be a good approach to...
