Customer satisfaction is one of the major objective of the organizations because satisfaction leads the customers to be loyal and this can be source of competitive edge for the organization. Therefore, this study is designed to investigate the mediating role of customer satisfaction between service quality and brand loyalty, corporate image and brand loyalty, perceived value and brand loyalty in the four distinct service sectors of Pakistan i.e. hospitals, educations, banks and hotels. The data were collected by using nonprobability sampling and snowball sampling from the students for determining educational sectors results and customers of other sectors to examine their results. The total 500 questionnaires distributed to respondents from which 440 (88%) were usable and able for testing. The results indicate that service quality, corporate image and perceived value are the key drivers in enhancing brand loyalty when customer satisfaction mediated in their relationship. The findings confirm the mediating role of customer satisfaction in the relationship of service quality and brand loyalty, corporate image and brand loyalty, perceived value and brand loyalty.

PurposeThis research attempts to empirically expand the Aaker's consumer based brand equity model in hybrid business firms by incorporating after sales service as a new dimension. Exploring and understanding the drivers of consumer based brand equity in a hybrid business context will help in building industry specific competitive barriers and generating brand wealth.Design/methodology/approachThe data were collected from Pakistani adults using a structured questionnaire based on established scales. Convenience sampling was used to gather data from 205 respondents across the major cities of Pakistan. To test the proposed research model the data were analyzed using confirmatory factor analysis.FindingsThe results support the proposed five‐factor model of consumer based brand equity for the automotive industry. The results support the notion that after sales service is related but is a separate dimension of consumer based brand equity in the automotive sector.Research limitations/implicationsThis proposed CBBE model was tested in the automotive sector of Pakistan. However, the automotive industry is special in the sense that it builds brands at dual level. This study only investigates consumer based brand equity at marque level. Future studies can expand on this work by investigating consumer based brand equity both at marque and model levels.Practical implicationsThe establishment of after sale services as a separate but independent dimension of consumer based brand equity for the hybrid business organizations provides a fresh reminder regarding the possibilities of new sources for building brand equity. Managers can focus on delivering excellent after sale services to build and enhance the equity of their brands in hybrid business organizations.Originality/valueThis study expands Aaker's brand equity model by empirically establishing after sales service as a fifth dimension for the firms operating on hybrid business model.

Friction stir welding (FSW) is one of the primary fabrication techniques for joining different components, and it has become popular, especially in aluminum alloy structures for marine applications. The welded joint with the friction stir process greatly depends on the process parameters, i.e., feed rate, rotational speed, and pin profile of the tool. In the current study, plates of aluminum 5451 alloy were joined by the FSW technique, and the Taguchi method was used to find the process parameters at an optimal level. The maximum value of tensile strength, i.e., 160.6907 MPa, was achieved using optimum welding conditions of a tool rotation speed of 1400, a feed rate of 18 mm/min, and the tool pin with threads. The maximum value of hardness, i.e., 81.056 HV, was achieved using optimum conditions of 1200 tool rotational speed and a feed rate of 18 mm/min with a tool pin profile having threads. In addition, the contribution in terms of the percentage of each input parameter was found by the analysis of variance (ANOVA). The ANOVA results revealed that the pin profile of the tool has the maximum contribution of 67.77% and 62.42% in achieving the optimum value of tensile strength and hardness, respectively. The study also investigated the joint efficiency of the friction stir welded joint, hardness at the weld zone, and metallography on FSW samples at the optimized level. The effectiveness and reliability of FSW joints for shipping industry applications can be observed by joint efficiency. That was investigated at optimum conditions, and it comes out to be 80.5%.

In this study, the ballistic impact behavior of auxetic sandwich composite human body armor was analyzed using finite element analysis. The auxetic core of the armor was composed of discrete re-entrant unit cells. The sandwich armor structure consisted of a front panel of aluminum alloy (Al 7075-T6), UHMWPE (sandwich core), and a back facet of silicon carbide (SiC) bonded together with epoxy resin. Numerical simulations were run on Explicit Dynamics/Autodyne 3-D code. Various projectile velocities with the same boundary conditions were used to predict the auxetic armor response. These results were compared with those of conventional monolithic body armor. The results showed improved indentation resistance with the auxetic armor. Deformation in auxetic armor was observed greater for each of the cases when compared to the monolithic armor, due to higher energy absorption. The elastic energy dissipation results in the lower indentation in an auxetic armor. The armor can be used safely up to 400 m/s; being used at higher velocities significantly reduced the threat level. Conversely, the conventional monolithic modal does not allow the projectile to pass through at a velocity below 300 m/s; however, the back face becomes severely damaged at 200 m/s. At a velocity of 400 m/s, the front facet of auxetic armor was destroyed; however, the back facet was completely safe, while the monolithic panel did not withstand this velocity and was completely damaged. The results are encouraging in terms of resistance offered by the newly adopted auxetic armor compared to conventional monolithic armor.
