The Forward and inverse kinematics of the robot is the connection of mechanical system motion and control system. There is no closed form solution for inverse kinematics of 6 DOF robots currently. The method of numerical iterative algorithm is used usually, but which is hard to ensure the requirement of real-time and accuracy. Considering the application and characteristic of cobot, we designed the...
Today, technology is enabling change in most of our lives. Also, crucial for most of these changes, are software startups whose contributions have led to the creation of a global market, jobs, and some help in fighting the "brain drain" pertaining in most developing countries. However, there is not enough academic literature to guide practitioners on how to leverage the collaborative potentials...
This study aims to develop a judgement approach for estimating potential customer demand in the O2O e-commerce environment. The taxonomy used is mainly methodology, and we design it as five steps to explore the topic. According to test results, we identified five types of combinations regarding feedback behaviour in dual channels of the O2O environment. We further analyse the relationships between...
The Routing applications are popular in Wireless Sensor Networks (WSNs). For a practical monitoring environment, the monitoring events may be varied, and so do the data sinks. Most of known applications deal with the monitoring without varied data. The varied event and different sinks are regarded as different monitoring systems. We propose a distributed mechanism to arrange the routing for transmitting...
In this study, the electrospinning machine with a remote control function was developed to fabricate the polymeric nanofiber mesh for tissue engineering application. The electrospinning machine composites of the three axises control system, stage controller with high-voltage bias power supply and remote control model. The conditions of fabricated nanofiber mesh, such as dimensions, geometries and...
In this paper, a cascade architecture of fuzzy controllers for nonlinear inverted pendulum pulley system is proposed to solve both angle and position regulation problem. In this architecture, the pendulum angle and the pulley position can be decoupled from the control force, and the angle and position controllers connected in series are designed independently. The fuzzy rule number and variable classification...
With the advance of information technology, video on the web (such as, Youtube) had been a common and convenient channel for learning by students. But the characteristics of transient information in videos are easy to impose a high cognitive load to students, especially for elementary school students. Because video is not a single text or a single image, which has rich colors and complex scenarios...
Rice Planthopper (RPH) infestation in paddy field is a serious disaster in Asia every year. Finding RPHs based on image processing is an important thing before RPHs growth. We propose a region of interest (ROI) method to detect RPHs clearly. First, get rectangle ROI in HSV space and do color analysis. By using decision tree algorithm, classify analytic data to get binary image of RPHs. The results...
Blended learning is a combination of multiple different instructional modalities, teaching methods and e-learning to develop a new learning model suitable for teaching in class. In this study, a teaching strategy for architectural design education is developed based on the theories of knowledge conversion and blended learning. This strategy is composed of offline teaching activities and teaching/learning...
Outdoor sports equipment without maintenance usually caused injury to users. This paper proposes to design an App notification system combine with IoT to monitor the equipment status. We converted our action signal into frequency domain for analysis. But the useless signal might decline classifier efficiency. Therefore we propose an empirical support vector machine (SVM) to reduce the useless signal...
In this study, titanium oxide (TiO2) photocatalyst film were prepared by liquid phase deposition (LPD) using a deposition solution of boric acid (H3BO3) and ammonium hexafluoro-titanate [(NH4)2TiF6]. The LPD-TiO2 films were deposited on Si substrate, and soaked in the methylene blue solution under UV irradiation at room temperature. The dye decolorization efficiency was improved with the high annealing...
In recent years, due to the advance of new technologies, the idea about intelligent tutoring system (ITS) has achieved many successes. The quality of the employed semantic space is a crucial element for establishing an ideal ITS. How accurate the student's responses can be identified and how precise the teaching content can be distributed all depend on the characteristics of the semantic space. A...
A Minor Incident is a personal creation of animated short film that reflects upon the essence of human integration. Through the comparison and combination of individual differences in existential values, this film investigates the essence of group integration. Interactions among various ethnic and cultural groups in Taiwan are presented with a metaphorical story where personification is applied in...
The purposes of this article are to examine the effect of payer vs. partial payers on consumer complaint behavior when encountering service failure and the mediating role of consumers' embarrassment avoidance in the relationship between payer vs. partial payers and complaint intentions. The results demonstrate that paying customers behave higher complaint intentions when they are alone than when in...
This paper presents an adaptive band-based super-resolution (SR) algorithm based on discrete wavelet transform (DWT). The original video sequence is divided into high-resolution key frames (KFs) and low-resolution non-key frames (NKFs). In general, DWT separates each frame (including key and upsampled non-key frames) into four bands (LL, LH, HL, and HH). With constructing conditional SR algorithm,...
In this study, we synthesized grafted polymers comprising a mesogenic aromatic polyester and side photochromic spiropyran fragments. Through π-π interaction between the aromatic rings in the polyesters, the extended polyester main chains form a layered structure. The space released between the layers preserves the photochromism of the spiropyrans. Through the structure changes in the spiropyrans under...
In robot teleoperation system, human operates and respond rely on what the video screen displays. However, unavoidable delays, such as network transmission, cause asynchronous communication between human and robot and further result in human operation errors, such as redundant or duplicate operations or even wrong commands. Different from users in large-scale industry, users in daily life may not...
This study presents an application of Iterative Learning Control Theory (ILC) for synchronization between two chaotic systems with output signal error. The iterative learning law illustrates the relationship between (i-1)-th iterative error output of drive-response system and iterative (i-th) input of response system. The error convergent describes the path response system tracking the trajectory...
Representational state transfer (REST) is the current design standard for Web Application Programmable Interfaces (Web APIs or APIs). Unfortunately, existing Web API search engines allow for only keyword or tag-based searches for RESTful services without considering advanced functionality, such as contextual recommendation or visualization. In this paper, we propose a novel approach, referred to as...
