  • Nowaday in the ubiquitous environment, the real-time remote control and monitoring technology for power grids or a similar system provides service as a sharable and independent of time-location for various contents to get from sensors or cameras of the system. In this paper, we introduce the real-time monitor and control system for photovoltaic system to evaluate the system performance and to keep the maintenance by using IMS (Internet Management System). To prove the pragmatic use of IMS, we applied the IMS in water management system. We designed feasibly to control on remote site by web-browser. It guarantees a continuity of real-time information transferring by IMS.

  • RIA(Rich Internet Application) has the best User Interface and easy way to use. It is used in many Application System and Web Application. This Paper introduces a RIA technology for Implementation of u-Hospital Application. This System uses a history of customers in the hospital and question about diseases, so we can improve the satisfaction of service. This paper shows that the u-Hospital System using RIA is more fast and easy than HTML application. Because RIA has special features that data can be obtained from server without reloading entire page and every user interaction does not require web server response. The proposed technology can improve the efficient u-Hospital System because it can be extended to ubiquitous mobile application.

  • Ubiquitous implementation of indoor location-based technology is recognized that one of the important elements of the technology. Specifically, the hospital management of patients, the silver-town management, the implementation of the smart home for the indoors rather than outdoors in a range of broadband users for location-aware technology is needed. This paper in wireless devices with an indoor location awareness shows about the system's technical design and implementation. Location-based technology for wireless LAN users aware of the strength of radio signals (Received Signal Strength Indication, RSSI) using trilateration. Topographic mapping system will be implemented wireless devices and servers, Access Point (AP), which is the system's development and testing throughout the physical environment to determine the potential for real-life applications.

  • ularly, a points of view Health-care system, it can reduce costs and efforts in order to management of patients. However, Health-care system keep a level of service for person and extends of hospital inner parts system. Although the rate of an addict grow by alcoholic but it is difficult to manage and diagnosis because of patient data gathering. Therefore in this thesis, it is proposed to patient data gathering and monitering method in u-zone. It can collect patient data by pulse, temperature and acceleration sensor and it can diagnosis correct based on emotion change data.

  • In a Ubiquitous sensor network environment, the sensor node is in general small and low price, and operating with power limited battery. The reliable TCP/IP protocol is used for transmitting sensed data from the sensor node. A new method was proposed in order to overcome the limitation of small embedded memory, but it is difficult to use for the case of frame error. In this paper, a new algorithm is proposed to manage the receiving frame error or loss, and it is appropriate to the sensor network to send sensed data periodically.

  • There are many free applications that need users to sign up before they can use the applications nowadays. It is difficult to choose a suitable password for your account. If the password is too complicated, then it is hard to remember it. However, it is easy to be intruded by other users if we use a very simple password. Therefore, biometric-based approach is one of the solutions to solve the issue. The biometric-based approach includes keystroke dynamics on keyboard, mice, or mobile devices, gait analysis and many more. The approach can integrate with any appropriate machine learning algorithm to learn a user typing behavior for authentication system. Preprocessing phase is one the important role to increase the performance of the algorithm. In this paper, we have proposed ensemble-by-session (EBS) method which to operate the preprocessing phase before the training phase. EBS distributes the dataset into multiple sub-datasets based on the session. In other words, we split the dataset into session by session instead of assemble them all into one dataset. If a session is considered as one day, then the sub-dataset has all the information on the particular day. Each sub-dataset will have different information for different day. The sub-datasets are then trained by a machine learning algorithm. From the experimental result, we have shown the improvement of the performance for each base algorithm after the preprocessing phase.

  • According to the ubiquitous usage of smartphone, so many smartphone applications have been developed, and especially data communications and position measurement technologies without additional equipments have been developed using acoustic signal. But there is a limitation to select the frequency of the acoustic signal due to the smartphone hardware, and there is non-linearity in the electronic circuits in a sound generation devices, the audible sound generated from the speaker is not avoidable. And it causes critical difficulty to the commercial system deployment. In this paper, a simulation technique to calculate the power of the audible acoustic signal by human is applied to several types of acoustic signals to evaluate the loudness. These could be referred when the acoustic communications or positioning systems are designed, for the purposed of inaudible sounding to human.
