Возможность управления качеством продукции, улучшение эксплуатационных характеристик, адгезии, износостойкости являются приоритетными направлениями в лакокрасочной промышленности. Один из способов влияния на качество лакокрасочных материалов (ЛКМ) – введение высокодисперсных добавок (ВДД) в полимерную основу. В работе осуществлялся подбор ВДД и способ их введения в краску с целью улучшения ее износостойкости, что важно при использовании, например, для дорожной разметки. Было изучено влияние трех типов ВДД: электровзрывного оксида алюминия, ультрадисперсных алмазов детонационного синтеза и оксида алюминия – глинозема (техногенные отходы Ачинского глиноземного комбината). Наибольший интерес в качестве высокодисперсной добавки для улучшения износостойкости полученных композитов представляет электровзрывной оксид алюминия. Установлено, что введение 0,05 масс. % взрывного Al2O3 позволяет увеличить износостойкость в лабораторных условиях на 25 % при сохранении других эксплуатационных характеристик в пределах требования нормативных документов. The ability to manage product quality, improve performance, adhesion, and wear resistance are priorities in the paint and varnish industry. One of the ways to influence the quality of paint and varnish materials (LCM) is the introduction of highly dispersed additives (HDA) into the polymer base. In the work, the selection of HDA and the method of its introduction into the paint was carried out in order to improve its wear resistance, which is important when used, for example, for road markings. The influence of three types of HDA was studied: electroexplosive aluminum oxide, ultrafine diamonds of detonation synthesis, and aluminum oxide-alumina (technogenic waste of the Achinsk alumina combine). Electroexplosive aluminum oxide is of the greatest interest as a highly dispersed additive for improving the wear resistance of the obtained composites. It was found that the introduction of 0.05 wt. % explosive Al2O3 allows you to increase the wear resistance in the laboratory by 30% while maintaining other properties.

Human resources are a valuable asset in the company, the Information System Multi Level Marketing (MLM) and good product quality will improve performance Member. This study aims to prove that the effect of the partial and simultaneous variable Information System Multi Level Marketing (MLM) (X1) and Product Quality (X2) to the Member-performance variable (Y) on PT Melia Sehat Sejahtera in Batam. The analysis used in this research is multiple linear regression analysis that has the objective to determine the magnitude of the regression coefficients which will show the level of influence of independent variables on the dependent variable. T test results showed that the variable Information System Multi Level Marketing (MLM) (X1) significantly affects the performance Member (Y) and Product Quality variable (X2) significantly affects the performance Member (Y). The test results show that F Information System Multi Level Marketing (MLM) (X1) and Product Quality (X2) the simultaneous effect against Member Performance (Y).

And Performance

A recent series of experiments suggests that fostering superstitions can substantially improve performance on a variety of motor and cognitive tasks ( Damisch, Stoberock, & Mussweiler, 2010 ). We conducted two high-powered and precise replications of one of these experiments, examining if telling participants they had a lucky golf ball could improve their performance on a 10-shot golf task relative to controls. We found that the effect of superstition on performance is elusive: Participants told they had a lucky ball performed almost identically to controls. Our failure to replicate the target study was not due to lack of impact, lack of statistical power, differences in task difficulty, nor differences in participant belief in luck. A meta-analysis indicates significant heterogeneity in the effect of superstition on performance. This could be due to an unknown moderator, but no effect was observed among the studies with the strongest research designs (e.g., high power, a priori sampling plan).

AbstractA Bayesian decision support system was developed for the diagnosis of rheumatic disorders. Knowledge in this system is represented as evidential weights of findings. Simple weights were calculated as the logarithm of likelihood ratios on the basis of 1,000 consecutive patients from a rheumatological clinic. The effect of various methods to improve performance of the system by modification of the weights was studied. Three methods had a mathematical basis; a fourth consisted of weights adapted by a human expert, which allowed inclusion of diagnostic rules such as defined in widely accepted criteria sets. The system’s performance was measured in a test population of 570 different cases from the same clinic and compared with predictions of diagnostic outcome made by rheumatologists. The weights from a human expert gave optimal results (sensitivity 65% and specificity 96%), that were close to the physicians’ predictions (sensitivity 64% and specificity 98%). The methods to measure the performance of the various models used in this study emphasize sensitivity, specificity and the use of receiver operating characteristics.
