in many manufacturing processes, the quality of a product is characterized by a non-linear relationship between a dependent variable and one or more independent variables. using nonlinear regression for monitoring nonlinear profiles have been proposed in the literature of profile monitoring which is faced with two problems 1) the distribution of regression coefficients in small samples is unkno...

Statistical process control is an excellent quality assurance tool to improve the quality of manufacture and ultimately scores on end-customer satisfaction. SPC uses process monitoring charts to record the key quality characteristics (KQCs) of the component in manufacture. This paper elaborates on one such KQC of the manufacturing of a connecting rod of an internal combustion engine. Here th...

A simple and rapid vortex assisted ionic liquid based liquid-liquid microextraction technique (VALLME) was proposed for preconcentration of trace levels of cadmium. According to this method, the extraction solvent was dispersed into the aqueous samples by the assistance of vortex agitator. Cadmium preconcentration was mediated by chelation with the 8-hydroxyquinoline (oxine) reagent and an IL, ...

results all doses of g. vitellinum extract induced anti-nociception activity during the first and second phases of the formalin test. the extract showed a significant (p < 0.05) dose-related inhibition during the first phase compared to the control group. in the second phase of the formalin test, the extract showed analgesic activity comparable to the effect of morphine. in pre-treatment with n...

abstract profile monitoring in statistical quality control has attracted attention of many researchers recently. a profile is a function between response variables and one or more independent variables. there have been only a limited number of researches on monitoring multivariate profiles. indeed, monitoring correlated multivariate profiles is a new subject in the fileld of statistical process...

Objective.To determine the expediency of spleen–preserving operations performance for its injury due to gun–shot thoraco–abdominal and abdominal woundings.&#x0D; Materials methods. Of 51wounded persons with penetrating woundings splenic injuries 8 (15.7%) were operated on II level medical help delivery, while ІІІ – 43 (84.3%). wounded persons, in 35 (81.4%) splenectomy was performed, (18.6%) or...
