In this article, a new algorithm that takes the truth vector of a 5-valued function as its input and proceeds to generate all of the function’s fixed polarity Reed-Muller (FPRM) spectral coefficient vectors one by one in a certain sequence is presented. The experimental results for this algorithm are compared with other methods and it was found that it is more efficient than other methods for s...

The research reported in this paper presents a new idea of the storage structure of sparse matrices. This structure is used in the multi-option solver of linear equation systems with unsymmetrical sparse coefficient matrices. The new solver is compared comprehensively with the analogous (identical numerical method used) solver of the classical type. The tests of new solver have been performed o...

Lie point symmetry analysis is performed for an unsteady nonlinear heat diffusion problem modeling thermal energy storage in a medium with a temperature-dependent power law thermal conductivity and subjected to a convective heat transfer to the surrounding environment at the boundary through a variable heat transfer coefficient. Large symmetry groups are admitted even for special choices of the...

the potential of vis-ir (400–1100 nm) transmittance method to assess the internal quality (freshness) of intact chicken egg during storage at a temperature of 307 oc and 25% 4 relative humidity was investigated. one hundred chicken egg samples were used for measuring its freshness and spectral collection during egg storage times (up to 30 days). two correlation models between haugh unit (hu) an...

objectives: almond (prunus amygdalus) hull and shell are agricultural by-products that are a source of phenolic compounds.the processing of almond produce shell and hull, accounts for more than 50% by dry weight of the almond fruits. recently, more studies have focused on the influence of storage conditions and postharvest handling on the nutritional quality of fruits, especially the antioxidan...

Modeling of regulating system of large pumped storage power station with long pipeline and parameters optimization in transient processes are studied in this paper. According to the actual parameters of a certain pumped storage power station, MATLAB/Simulink toolbox is utilized for modeling and simulation of its subsystems. Friction resistance coefficient and water elasticity are taken into con...
