Magnetic levitation system with the advantages of non-contact, no friction and no wear can satisfy the requirement of high precision and high speed positioning. In this paper, magnetic levitation positioning stage which mainly consists of planar coil and HALBACH permanent magnet array and its control and driving system are designed. Magnetic levitation system is a highly nonlinear and strongly coupled complex system and its control performance can be influenced by the uncertainty and external disturbance. So exact feedback linearization method is used to realize exact linearization and decoupling, and a strategy of sliding mode control based on disturbance observer is proposed to compensate the uncertainty and external disturbance. Detailed proofs of observer's convergence property and system stability are derived. Both the simulation and experiment results verify the effectiveness of sliding mode control algorithm based on disturbance observer.

Consumers are becoming more demanding and due to a wide range of products in different markets, make demands that are more stringent on companies. The goal of this article was to study the main trends of branding and advertising on social networks to develop a new approach to brand promotion. Methodology. The quantitative and qualitative research design was used to determine the main trends in branding and advertising on social networks. The methodology included the following methods: 1) analysis of the relationship between brand value and brand content strategy, 2) content analysis of the content of companies in social networks on the example of 10 world-famous brands with the highest value. The results allowed forming the criteria of effective content and communication: simplicity of content and simplicity of communication, lack of direct advertising of products, emphasis on global socio-economic problems and social orientation, unobtrusive communication, content creativity, indirect information about the product or work, the history of the company's development through various tools. The main content strategies of brands are defined: storytelling strategy; strategy of informing about the history of the company's development; entertainment and information strategy; strategy of joint interaction with the audience through the involvement of wellknown influencers or users of products. The theoretical and practical value of the results is confirmed by the conceptualization of the main content strategies of world-famous brands, which are pioneers in new ways to build relationships with users through social networks. The research proposes to use a customer-oriented approach to brand promotion. This means studying consumer behavior and predicting possible changes in behavior, which determines the level of interaction with the brand, the content strategy of the brand, and its effectiveness.

This paper discusses an autonomous navigation system for urban environments. For the localization of the robot, EKF (Extended Kalman Filter) algorithm is used with odometry, angle sensor, and DGPS (Differential Global Positioning System) measurement. Especially in an urban environment, DGPS is often blocked by buildings and trees and the resulting inaccurate positioning prevents the robot from safe and reliable navigation. In addition to the global information from DGPS, the local information of the curb on the roadway is used to track a route when the global DGPS information is inaccurate. For this purpose, curb detection algorithm is developed and implemented in the developed navigation algorithm. Four different types of navigation strategies are developed and they are switched to adapt to different localization conditions according to the availability of DGPS and the existence of the curbs on the roadway. The experimental results show that the designed switching strategy improves the navigation performance adapting to the environment conditions.

This paper presents a satellite relative navigation strategy for formation flying, which chooses an appropriate navigation algorithm according to the operating environment. Not only global positioning system (GPS) measurements, but laser measurements can also be utilized to determine the relative positions of satellites. Laser data is used solely or together with GPS measurements. Numerical simulations were conducted to compare the relative navigation algorithm using only laser data and laser data combined with GPS data. If an accurate direction of laser pointing is estimated, the relative position of satellites can be determined using only laser measurements. If not, the combined algorithm has better performance, and is irrelevant to the precision of the relative angle data between two satellites in spherical coordinates. Within 10 km relative distance between satellites, relative navigation using double difference GPS data makes more precise relative position estimation results. If the simulation results are applied to the relative navigation strategy, the proper algorithm can be chosen, and the relative position of satellites can be estimated precisely in changing mission environments.

A decade has passed since the first generation of Genesis was launched in the U.S. with the plaque of Hyundai-Genesis. Genesis Motors was separated from Hyundai Motor in 2015, and has struggled to have the Genesis stand alone in the competitive U.S. luxury sedan market. The present case study aims to find challenges facing the Genesis, which Hyundai has positioned as a luxury sedan competing against conventional luxury brands such as BMW, Mercedes-Benz, and Lexus; evaluate Genesis Motors' strategic response to meet these challenges; and explore an alternative positioning strategy. Specifically, the present case study addresses barriers against the Genesis' market performance, by focusing on the obstacles rooted in the consumer perception as well as the obstacles that stem from the change in the U.S. automobile industry and the nascent network of the Genesis dealership. Genesis Motors' current strategies are evaluated, and an alternative strategy is explored that is largely based on the American consumers' perceptions of the Genesis vis-a-vis conventional luxury brands and outperforming midsize brands.

The purpose of this study is to investigate any differences in perception of fashion brand positioning between a manufacturer and a consumer. So this can provide theoretical suggestions for the development of brand positioning strategy for fashion brand. For this study, three brands, (MINE, TELEGRAPH, and MICHAA,) were selected by the criteria. The data were collected via a selfadministered questionnaire and analysed by the statistical method. The results of investigation were as follows: 1. The consumers had good attitudes in the order following: MINE, MICHAA, and TELEGRAPH in the factors1). In the case of purchasing the goods, the result of the research showed presented that the consumer had better attitudes than in the case of unpurchasing the goods. Contrary to our expectation, TELEGRAPH has the best attitude in personality, one of the factors. 2. In the image positioning map between the manufacturer and the consumer, the consumer had the same perception about the manufacturer. However, there is a gap on the degree of agreement for positioning map. In the case of purchasing the goods, the result of the research represents that the consumers are similar to the manufacturer in perception of the image positioning. 3. In the results of forming attitudes and recognizing brand by the consumer, there is a difference in brand positioning. The display and the shop appearance are very important means of attractions very to the consumers but salesmen‘s service or direct mail (DM) do not appeal to the consumer.

Recently the market environment surrounding business firms has been remarkably changed due to the increasing variety of consumption value and taste. On account of technological gap becoming narrower among business firms, the most important thing is for the soft value, such as that of emotional and subjective factors, in order for business firms to be able to create such strategic positioning, for which business firms should first look carefully into latent needs and values of the consumers. Since such products possessing those factors are able to supply the consumers with an appropriate value in attractive forms and meanings, new product development for the valuable products initiates a very important strategic action for securing the strategic positioning. The purpose of this paper is to study the strategic position and role of design in new product development strategy. Design has become the momentous competence of an enterprise in the most recent. Design performs its strategic role as a bridge between a business firm and the consumers. Consumers perceive value added by their purchase of products with attractive designs offered by business firms and, then, satisfy their emotional and subjective value with the products. This study, however, reviewed a new angle on the role of design as an implement for discovering consumers' latent needs and values which could be main factors for obtaining the strategic positioning. In other words, this study intended to suggest a new strategic role of design as value suppliers in new product development strategy for firms formulating and implementing their business strategies. For the new angle on the role of design, this study discussed a new approach of design strategy and intended to formulate its system first. And then, it suggested a general idea for strategic design analysis and its methodology, ethnography, as a strategic value creator. Finally, the suitability and usefulness of strategic design analysis for new product development strategy was discussed.
