Data were collected from all related agencies. The results of this research have showed that executive process of forensic science is used to investigate the crime in three southern border provinces that can be divided the operations into three main issues as following: crime scene examination, evidence testing, autopsy in case of crime scene, and factors which affect forensic work for using in criminal investigation in three southern border provinces of police practitioners. They should have the knowledge about forensic science, commitment, bravery, and cunning work.展开更多

The proposed method involves the mathematical programming techniques to seek the regression coefficients for the calibration model calculation. It is based on the optimization theory used for finding the extremum of the objective function in the given domain of a vector space and employs the method of the complementarity problems solving. The MPM algorithm is described in detail. The MPM was tested on an InfraLUM FT-10 NIR analyzer of Lumex company with samples of dry milk (for fat), corn (for protein) and rye flour (for moisture). The obtained results show that the MPM can be used for constructing multivariate calibrations with the qualitative characteristics superior over those of the classical PCR and PLS methods of analysis.展开更多
