A test fleet including 47 gasoline vehicles with 6 different technical types was organized, and the adaptability of these vehicles under China 6 standard was studied. By analyzing the performance of the vehicles tested in laboratory and in real-world, technical types that could simultaneously reconcile emission and fuel consumption performance were proposed. The results show that all vehicles were well performed under laboratory conditions, but in real-world conditions, 50% direct injection vehicles without GPF would fail the RDE test. On the other hand, vehicles with GPF had better performance, all of which passed the RDE tests even if the conformity factor decreased from 2.1 to 1. In addition, it is found that the fuel consumption of the DI vehicles were lower than that of the PFI vehicles. As the DI vehicles with GPF showed better performance on the balance of emission and fuel consumption, indicating that they may have better potentials to deal with the increasing tightened emission and fuel consumption standards at the same time.

The objective of the present research is evaluating the effect of the brand equity on the repurchase intention by mediation of the brand attractiveness and brand trust. The present research is applied and descriptive- survey. The population of this study include 188 staff of Iran insurance company in Hamedan city. The volume of sample considering the Morgan table equals to 127 people. The sampling method is simple random method. Data gathering tool is standard questionnaire. The conformity factor analysis method was used in order to validity examination. The Cronbach’s alpha was used for reliability evaluation LIZREL Software was used for date analysis of the structural equations modeling. the obtained results indicated that the brand equity, the brand attractiveness and brand trust have a positive and significant effect on the repurchase intention of Iran insurance company of Hamedan.

Abstract The current EURO 6c standard has introduced a limit on the number of solid particles for spark ignition engines equal to that for compression ignition engines (6x10e11). To meet the requirements, manufacturers install particulate filters in the exhaust systems of most new engines. The article presents the results of vehicle testing with this solution during the drive carried out in accordance with the RDE procedure. The measurement results, after taking into account the Conformity Factor in relation to the approval limits, confirmed the efficiency of aftertreatment system in terms of both gas and solid components.

The factorial validity of an Afrikaans translation of the Comrey Personality Scales, was investigated using a sample of 804 South African university students. Nine factors were extracted and rotated. Eight of the factors were clearly recognisable as the eight factors that comprise Comrey's 1970 taxonomy of personality traits. Coefficients of congruence indicated that seven of the factors were very similar to the factors obtained in the American normative sample. Loadings for The Social Conformity factor were not as high as expected, but this may have been due to the fact that the participants were nonvolunteers who may have been hesitant to reveal nonconforming attitudes and behaviors. These results lend additional support for the factorial validity of the traits in Comrey's taxonomy which have now been identified and replicated in several countries and languages.

Conformity factor, which is more rationally defined as the ratio of the area of contact to the active area of the flank of the mating teeth, is theoretically evaluated for Wildhaber-Novikov circular-arc gears, using Hertz’s theory of contact stress, without neglecting the effect of the difference in the profile radii of the pinion and wheel teeth, which is an important factor in fully-hardened gears. The variation of the conformity factor with the helix angle, pressure angle, ratio of the profile radii, module and the number of teeth follows closely the variation of load-carrying capacity per unit face-width of these gears and hence, from this study it is concluded that conformity factor is a more rational index on which the selection of the profile and material parameters should be based. This study of the conformity factor, for the particular profile geometry, indicates 7.5 to 15.0 deg as the suitable helix-angle range for achieving maximum load-carrying capacity per unit face-width.
