The whole face economical downfall throughout their lives, including Taiwan where consumers are struggling with the drastic skyrocketing price tags of products and their never-increase incomes. Nowadays, there are more and more brands in which have similar line, and thus relying on the quality itself doesn't seem ra-tional enough to stay on top of the business world. So it all depends on the consumers...
The driving system is gradually improving with the development of technology, especially for the passive safety system. However, according to the statistics of traffic accidents in Department of statistics, Ministry of Transportation and Communications R.O.C. (MOTC), there are 274,042 traffic accidents in average in the past five years. Among them, the total amount of accidents in category A1 has...
In this paper we propose and evaluate an auction-based resource allocation mechanism in a cloud-based radio access network (C-RAN), where the spectrum is managed by several mobile virtual network operators (MVNOs) and the physical resource is owned by the C-RAN operator. Technically, our approach consists of two coupled auctions in a hierarchical way: the lower-level auction between end users and...
In this paper we report how we improve our Chinese grammar error detection system. We focus on the recognition of word selection error, which is the hardest error type defined in 2015 NLP-TEA shared task CGED. Four major error types was defined in CGED shared task, including redundant word error, missing word error, word selection error and word disorder error. Based on the conditional random fields...
This paper proposes a new wearable eye-gaze tracking system with a single webcam mounted on the glasses. First, the region of interest (ROI) of eye is extracted by skin detection and eyelid removing. Then Hough circle detection is used to search the candidate of circles in the eye's ROI and applied to determine the status of opening or closing of eye. Based on the circle detection, the eye center...
Spectrum-based fault localization aims to find the program statements that contain faults, according to the dynamic information of executing program. We propose a spectra-based fault localization method with test case reduction, which removes redundant test cases in fault localization. Experiments show that new method requires fewer test cases to obtain the better fault localization results.
Developing intuitive interface to control humanoid robots with high degrees-of-freedom (DOF) in real-time remains as an essential issue. Since most humanoid robots have at least sixteen DOF, achieving real-time performance in controlling humanoid robot posture is hard to accomplish. This paper proposes a method to calculate joint angles of humanoid robots according to human's joint locations tracked...
Sensing falsification is a key security problem in cooperative spectrum sensing for cognitive radio networks. Most previous approaches assume that malicious users only cheat in their sensing reports following a predefined rule. However, some malicious users usually act intelligently to strategically adjust their malicious behavior according to their objectives and the network's defense schemes. The...
With the evolution of computer science technology the concept of clouds are kept booming. The management of a large number of computer and peripheral equipment becomes an important issue. For centrally managing such a large number of computers and peripheral equipment scattered in many longdistance locations, the IP-based peripheral equipment is presented in the market today. The smart automatic management...
Design pattern is an effective way to describe software architecture. But with the increasing size and complexity of the software, it is difficult to recognize design patterns are used in software. In order to comprehend and maintain software system, a lot of detecting design pattern algorithms were proposed. In this paper, we proposed an algorithm to discovery design patterns more efficient by automatic...
Low-rate denial-of-service attack is a novel category of attacks that are based on exploiting the adaptive behavior exhibited by several network and system protocols. This attack through periodically non-suspicious low-rate attack pulsing, to reduce the performance of the victims. Based on the simulation of low-rate denial-of-service on NS2 platform, we analyze the defense performance of queue management...
This paper provides a novel framework for semantic representation of Chinese news based on conceptual network which is described hierarchically in three layers. we first define the structure of independent concept that is the basic element of the framework. Then the domain specific semantic unit called knowledge node is illustrated. Finally, the knowledge tree which gives a well formed semantic hierarchy...
This paper presents an improvement to ordinary voice filters that are unable to remove low frequency noise. This problem occurs because their filter parameters are over tuned, thereby destroying the speech characteristics. The proposed scheme combines NLMS, Fuzzy logic and Kalman filtering to restrain the background noise and keep the speech characteristics. This scheme is called the Normalized Fuzzy...
