A good automated testing tool could reduce as much as possible the manual work done by testers. In order to improve the traditional record-replay approach and reduce the effort that the testers spending on writing test scripts, we propose an approach that generates the Android application test scripts based on accessibility service without connecting to a computer. This approach simulates user input...
A smart home system can provide better services to assist users if it knows what user activities will occur beforehand. Early research in activity prediction has indicated that the result of prediction is unique, but the accuracy remains unsatisfactory if only one result is considered. To solve this problem, this paper proposes a method of leveraging multiple models. In this work, we use a Bayesian...
A hybrid course curriculum design and implementation based on CDIO approach to engineering education is presented. The course is “fundamentals of electric circuit” for undergraduates of electrical engineering and automation program. The relation of the university motto is analyzed and mapped to CDIO directly. The curriculum design conducts CDIO ideas to classroom teaching, lab experiment and other...
This paper presents realization of positioning based on DTMB (Digital Television Terrestrial Multimedia Broadcasting) and GPS (Global Positioning System) in urban or indoor environment by means of a Software Defined Radio (SDR). DTMB signal's unique feature in super-frame is analyzed and a new correlation method without generating local PN sequence is proposed. Double delta correlator and Kalman filter...
Customer satisfaction is an fatal part applied in the consistent self-improvement of an organization. It is usually regarded as the most reliable and effective feedback system to make enterprises understand customers' expectation and preference accurately. This paper reviews the convention satisfaction studies firstly, then suggests the assessment structure of convention customer satisfaction. Based...
This paper describes our work on developing a language-independent technique for discovery of implicit knowledge about patents from multilingual patent information sources. Traditional techniques of multi- and cross-language patent retrieval are mostly based on the process of translation. One major problem of those is that it is difficult to find related patents produced from other countries in a...
Recommender systems can help people to find interesting things and they are widely used in electronic commerce. Collaborative filtering technique has been proved to be one of the most successful techniques in recommender systems. The main problems of collaborative filtering are about prediction accuracy, response time, data sparsity and scalability. To solve some of these problems, this paper presented...
