This study intends to examine the relationship of Brand image, Brand attachment, low price, past experience, and attitude on consumer purchase intentions in the context of counterfeit mobile phones in Pakistan. A sample of 153 students with the help of a questionnaire ISSN 2161-7104 2014 www.macrothink.org/jpag 2 containing 28 statements related beliefs about counterfeited mobiles was taken. The data were analyzed using linear regression using SPSS. The findings support the significant influence of past experience and low price on attitude towards counterfeit mobile phones. Positive association between past experience, Low price and attitude towards counterfeit mobile phones were found and there is also a positive association of attitude with young consumer's purchase intentions. Strangely, low price was not significant in influencing the purchase intentions. Brand image and Brand attachment were also found no significant in influencing purchase intention of customer. For both practitioners and academics, the findings of this study hold important implications. The paper guides the policy makers and academics about the main predictors of consumer's attitude towards counterfeit mobile phones.

In this work, a novel application of Active Magnetic Bearing (AMB) is proposed to integrate AMB in the Magnetically Coupled Thruster (MCT) assembly for underwater application. In this study, a 2-Degree-Of-Freedom (DOF) AMB is developed and investigated for the MCT of an Unmanned Underwater Vehicle (UUV). The paper presents the detailed electro-mechanical modeling of the in-house developed AMB system. The intractable problem of rotor suspension and rotation with opposing pairs of electromagnets is considered. A Linear Quadratic Gaussian (LQG) controller is designed and analyzed in the frequency domain for the stabilization of the open-loop unstable AMB for MCT. The performance specifications of the controller, such as reference tracking and disturbance rejection are achieved and evaluated through real-time implementation of the controller. The compensator also performed reasonably well during the dynamic operations, i.e., when the rotor-propeller assembly was spun at 1500 rpm. This rotor speed is needed to generate a thrust of 40–45 N and up to 1 m/s forward velocity, which is necessary to propel the UUV under consideration. By deploying AMB in MCT assembly, it is anticipated that problems associated with the conventional directly coupled thruster operating in harsh underwater environment, such as water ingress into electronics compartment, rusting, lubrication, and vibrations would be eliminated.
Due to combination of factors, such as environmental concerns, high oil prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world. Use of Gasoline as an alternative fuel in Gasoline engine is becoming a need, looking at the scarcity of petroleum fuels in near future. This paper investigates the influence of compression ratio and ethanol-gasoline blending to find the effects on four-stroke SI engine performance. In this research, air cooled engine having compression ratio of 9.1 & 9.7 is used. Fuel blend E50 is used in the study and engine operated at a speed range of 600-1100 rpm. Maximum power was obtained for E50 fuel at a compression ratio of 9.1, while, a minimum fuel consumption rate was obtained at a compression ratio of 9.7. This clearly depicts that as compression ratio increases, fuel consumption rate decreases considerably. Further, experimental results showed that comparing several blends, 50% ethanol is cost and power effective for the four-stroke SI engine.
