Lifting method through the use of hydraulic jacks, can adjust column elevation of the structure in order to eliminate the stress burden caused by differential settlement , as well as recover the structure¡¦s initial state and force to avoid the form reconstructing caused by different over-settlement, save construction cost and reduce environmental impact, and so the life cycle of the building be able to last. The study based on ¡§The computer control system of hydraulic jacks¡¨, ¡§The repair method of settlement of floating roof tank¡¨, and the other technologies, which developed by lifting method development department, set up by the case company, has matured day by day to seek permanent development strategy through the utilization of the innovative lifting method in structure on reclaimed land or tanks, shop buildings, and structures which have different settlement problems, and so on, enable to last the life cycle of the building. This study consists of the information collection of lifting technology development through the literature of innovative technology and management strategy and interview of the owner and the decision-making manager of the case company, that total sum of person-time is 21, with the theme of the technical development of lifting method, the extension of market, and the internationalization. Making industry S.W.O.T analysis can not only find out the lifting development business of the case company but also the strategic direction, core competitiveness, the development direction, the permanent strategy to maintain the annual growth of the rate of marginal balance. According to research, the case company need to become a international company in order to maintain the annual growth of 20¢H of the operational goal. Taking Taiwan as the technical development center, the case company uses the local manpower and constructional material of the group¡¦s subsidiaries in overseas footholds to lower the quote cost and enhance the competitiveness, so that the case company can move toward internationalization gradually. Besides, to be competitive in lifting industry, the case company must be customer oriented, which means to design the unique custom-made lifting method for the customer¡¦s demand. Contenting customer¡¦s demand with cost, industry safety and time is the most important strategy to retain long-term competitiveness advantage. In strategic growth oriented, to be the top lifting company all over the world after one decade, the case company has to enhance core competitiveness of lifting method, including project management, project control, structural design capacity, computer control hydraulic jacks system development capabilities, and technical capabilities lifting. Meanwhile, the case company has to develop continuously new technologies and methods, combine with the group¡¦s subsidiaries to establish overseas footholds to extend the overseas market, train staff to obtain the international certificate and learn the second language, and makes the product and service different from other companies.

Artifacts are signals that manifest in the EEG signal but do not come from the brain but from other sources such as flickering, electrical noise, muscle movements, breathing, and heartbeat. The proposed algorithm makes use of concepts and knowledge in the field of signal processing, such as signal energy, zero crossings, and block processing, to correctly classify the aforementioned artifact signals. The algorithm showed a 90% detection accuracy when evaluated in independent ten-second registers in which the gestural events of interest were induced, then the samples were processed, and the detection was performed. The detection and identification of these devices can be used as commands in a brain–computer interface (BCI) of various applications, such as games, control systems of some type of hardware of special benefit for disabled people, such as a chair wheel, a robot or mechanical arm, a computer pointer control interface, an Internet of things (IoT) control or some communication system. / Revisión por pares
