Radio Frequency Identification (RFID) systems consist of Electric Tags, or transponders and RF tag readers, or transceivers. Auto-tags of the RFID system have the unique ID feature and are capable of carrying information, which adds the tags more capability of which could be read only or read/write. RFID systems are now being used by more and more organizations connected with management, tracing,...
Ecological footprint model is an important means for quantitative evaluation of eco-city, to get rid of the defect of general ecological footprint model; we proposed a modified model by using emergy theory. In the calculation of ecological carrying capacity, we added the carrying capacity of actual product output and virtual product supply based on the material input-output and people's initiative;...
Emergy analysis system was established for eco-campus, different types of emergy can be unified into a comparable value; through analysis, the range reflects the economic environment and emergy indicators. It combines socio-economic system with natural system to form comparable entity. Depending on the data of Tianjin Polytechnic University old campus, new campus and Tianjin University, emergy analysis...
This paper presents discrete wavelet transform (DWT) and short-time fourier transform (STFT) applications for different industrial applications. These two transforms have been compared in different fields, and their implementations are similar. The experiments and simulations show another aspect for both transforms in order to analyze the target information.
This paper presents a multi-loop control approach for dynamic modeling, self-balancing and position control of a ball robot (Ballbot) with inverse mouse-ball driving mechanism actuated by two independent brushless motors simultaneously. A completely non-decoupling dynamic model of the robot incorporating with viscous and static frictions is derived using Newtonian mechanics. Two multi-loop controllers...
In this study, a new alternating-pressure air cushion (APAC) is designed and fabricated to render, for pressure ulcer prevention, a sufficient rest for the skin tissue in contact with the user's body pressure. The APAC designed comprises six cylindrical air bags and conforms to human factors or ergonomics. The inflation/ deflation system adopts a microcontroller IC chip to drive the pump and four...
This article presents the implementation of a Shell for the development of Fuzzy Specialist Systems. This Shell is being developed using the C++ and Visual Prolog languages. It allows the creation of a group of fuzzy rules. The Visual Prolog language is being used for the implementation of the inference engine. The C ++ is being used for the development of user interface, which is the creation of...
Wireless networked control systems have begun to gain acceptance during the last decade, due to the increased flexibility and lower costs they promise to provide compared with wired installations. The pace of application has been held back, however, by the reluctance of industry to make the accommodations necessary to allow wireless paths to be incorporated safely in process control loops, thus limiting...
This paper presents the stability analysis for polynomial fuzzy systems by utilizing the equality constraints of sum-of-squares (SOS) Program. Recently, T-S fuzzy systems have been extended to polynomial fuzzy systems, in which the consequent parts could be polynomial sub-systems. Moreover, stability and stabilization analyses for polynomial fuzzy systems have been done based on polynomial Lyapunov...
This paper presents a novel design of visual servo control of a mobile manipulator for autonomous grasping of a target object. In this design, scale invariant feature transform (SIFT) algorithm is adopted to search and recognize the object to grasp. Random sample consensus (RANSAC) algorithm is used to remove outliers and find the refined homography matrix between database and current image. Robust...
Since 1978' reforming and opening up, the economy has been in transition in China which accelerated the institutional changing as well as economic structure reconstructing and upgrading. In this paper, we apply Multiple Linear Regression analysis the relationship between economic transition and varieties industry development in Beijing, Tianjin and Shanghai. The conclusion shows, in different scene,...
This paper investigates the issues of torque control strategies for light electric bike systems with human power assistance. The feature of this electric bike equipped with both usual electrical machine power and personal-dependent human power makes its operation distinct from other types of vehicle. To facilitate a reliable and smooth torque control design, a speculation of the human torque exerted...
PSR model is a multivariate method that allows evaluation of a network of relationships between manifest and latent variables. Given the interesting features of this method and world-wide used, it is quite surprising that the number of proper applications in regional ecological health assessment is limited. As a case study in Hangu District, Tianjin, China, the index system was set up by using the...
Advances in storage capacity means that digital cameras can store huge collections of digital photographs. Typically such images are given non-descriptive filenames names such as a unique identifier, often an integer. Consequently it is time-consuming and difficult to browse and retrieve images from large collections especially on small consumer electronics devices. A strategy for classifying images...
A real time V shape hand gesture recognition system by motion history template matching is proposed in this paper. Initially, user moves one of his/her hands in a specified region for template setup. Then, possible moving hand regions can be extracted by overlapping motion masks and skin color image. After noise removal of these regions, motion history template matching is used to recognize the V...
This paper describes the modeling and control of a flexible joint robot considering actuator saturation. We design a composite controller for a single flexible joint robot. This controller consists of a composite structure, with a PD controller on the fast dynamics and a PID controller on slow dynamics. Up to the present time, PID controller has been widely used to control industrial process loops...
In 2009, the U.S. News and World Report magazine named Mayo Clinic a best hospital for 20th straight year, and ranked number 2 in the Honor Roll. In this paper, the basic reason of success of Mayo Clinic is studied by use of the concept of systems ethics. The initial development of systems ethics in Taiwan is presented first. Then, a brief review of the history of Mayo Clinic is made. Finally, the...
Technology industry is changing in the current. Mechanical arm is widely used in industrial automation, minimally invasive surgery, complex and sophisticated products, even dangerous for the implementation of the tasks of human. Mechanical arm has brought great convenience in human life, and full of vast opportunities. This paper presents the design of an automatic and intelligent mechanical arm with...
This paper presents a decision support tool for the effectiveness of a Quality Management System (QMS) in a company. To develop this tool, a new approach PAHP based on the combination of the Pareto Optimality Concept (POC) and the Analytical Hierarchy Process (AHP). This approach is used to model and optimize the multi-objective function of real company which presents a major problem for controlling...
