As a matter of fact, nowadays Due to the increasing rate of competition between companies and organizations, high level of customer and consumers’ expectations, increased cost of advertising and investment, the concept of "Brand Personality and all impressive factors affecting that concept", have been considered noticeably. This paper is determined to consider "Human personality" as the most important factors affecting brand personality. Hence, this study has an applied aim and follows an experimental method and its purpose is to identify the relationship between “Brand personality” and “Customer personality”. This designed research model is based on a mixture of Aaker's brand personality (1997) and Ekelund’s customer personality (2008). Content validity and structure of research questionnaires. In order to analyze data derived from questionnaires, proportional to statistical needs Statistical Package for the Social Sciences software (Smart PLS) is used. The hypothesizes of this study is about the existence of any significant relationships between “Customer personality” and “Brand personality”. In regard to the result of all data analysis, all of the hypothesizes except one is approved the main idea of this study. It means the way that people perceived brands is mainly based on the type of their opinions, beliefs and personalities.

In this paper a new systematic method for deriving the equation of motion of n-rigid robotic manipulators with revolute-prismatic joints is considered. The equation of motion for this robotic system is obtained based on Gibbs- Appell formulation. All the mathematical operations are done by only 3x3 and 3x1 matrices. Also, all dynamic characteristicsof a link are expressed in the same link local coordinate system. Based on the developed formulation, an algorithm is proposed that recursively and systematically derives the equation of motion. Finally, a computational simulation for a manipulator with three revolute-prismatic joints is presented to show the ability of this algorithm in deriving and solving high degree of freedom of robotic system.

The main purpose of this paper is to derive the inverse dynamic equation of motion of n-rigid robotic manipulator that mounted on a mobile platform, systematically. To avoid the Lagrange multipliers associated with the nonholonomic constraints the approach of Gibbs-Appell formulation in recursive form is adopted. For modeling the system completely and precisely the dynamic interactions between the manipulator and the mobile platform as well as both nonholonomic constraints associated with the no-slipping and the no-skidding conditions are also included. In order to reduce the computational complexity, all the mathematical operations are done by only 3×3 and 3×1 matrices. Also, all dynamic characteristics of a link are expressed in the same link local coordinate system. Finally, a computational simulation for a manipulator with five revolute joints that mounted on a mobile platform is presented to show the ability of this algorithm in generating the equation of motion of mobile robotic manipulators with high degree of freedom.

Background & Aim:: One of the problems in removable dentures is gradual color changes of the teeth. Which could results in patient dissatisfaction. This study designed to investigate the effect of without alcohol listerin mouth wash (Johnson & Johnson) on two types of composite resin teeth (YAMMAHACHI & APPLE).Material & Method: This experimental in-vitro study has been done on upper central incisor: 15 samples of artificial tooth APPLE (Ideal Makoo -Iran: A1, 17) and 15 samples of artificial tooth (yammahachi: A1, S8).Color measurements of teeth were performed by using spectrophotometer and recorded before immersion. Color change values were determined after 14 and 28 days. Color differences were characterized using the CIE lab color space. Statistical analysis was performed with T-Test for each dental group and eventually the PAIRED T-TEST was used for comparing the results of two groups.Results: This study performed on 30 spicies. color changes for YAMAHACHI and APPLE were equal to 1.60±0.83and 1.65 ±0.96 respectively (p<09) after 14days follow up -, color changes for YAMAHACHI and APPLE were equal to 1.99±0.86 and 2.32±0.94, respectively. (p<0.4) after 28 days follow up -color changes for YAMAHACHI was equal to 0.59±0.38 Between 14-28 follow up days -color changes for APPLE was equal to 1.00±0.47 (p<0.005) Between 14-28 follow up days Conclusion: It seems by time passes, color change of Apple artificial tooth is more than Yamahachi artificial tooth.

The purpose of this research was to analyze the effects of Apple-Samsung lawsuits on the two companies’ pricing and marketing strategies. This study was practical in nature and was considered a descriptive case-study research. To this end, legal cases between the two companies during 2011-2018 were investigated, and more specifically, 13 of them with public access during 2011-2012 were scrutinized. Furthermore, historical data of the two companies’ product prices and smartphone market penetration in the United States and other countries in the dispute were extracted. The main focus of this research was on utilizing the game theory concepts for modeling the litigations. First, a game of ‘ building a case against the competitor’ was identified followed by another game of ‘ infringing or not infringing the competitor’ s patent(s)’ . It has been shown that the latter was the source of another infinite recurring sequence of games that, according to the Forgiving Trigger Strategy, has led to the desired outcome for both companies. Perusing the financial outcomes of the lawsuits and heeding the fact that net profits of the two companies were negligible, other factors were identified including an increase in the market share and the prevention of price-wars over the creation of these lawsuits. In this regard, the goal of the two companies was to increase the customer lifetime value. Also, the reasons for stopping further prosecutions by the two companies were studied, and the question of why Apple never engaged in a direct legal dispute with Google itself– the creator of the Android operating system– was analyzed. Finally, some predictions were made about the likelihood of new patent wars.

The purpose of this study is to investigate the impact of innovative marketing on brand loyalty with the mediating role of customer satisfaction (Case study: Apple brand) using the model of Gupta et al. (6102) and Vera and Torrigio (6102). To investigate the study, a sample of 583 people was made available through the Telegram channel and Instagram pages. Data collection tool was a standard questionnaire with 62 questions whose validity and reliability were confirmed and distributed among the statistical population. Data analysis was performed using descriptive statistics and inferential statistics. At the level of statistics, descriptive indicators such as frequency and frequency percentage; At the level of inferential statistics from correlation methods, structural equation modeling, path analysis has been performed; For this purpose, SPSS and LISREL software were used. The results of the analysis indicate the positive and significant impact of innovative marketing on brand loyalty both directly and indirectly through customer satisfaction among Apple brand customers.
