The paper introduces a "lazy" Data Mining technology, which models students' learning characteristics by considering real data instead of deriving ("guessing") their characteristics explicitly. In former work, the authors developed a modeling system for university learning processes, which aims at evaluating and refining university curricula to reach an optimal learning success...
To support development processes for nanodevices, we want to utilize the information related to experiments from nanodevice development research papers. In this paper, we propose a new guideline for constructing a tagged corpus of nanodevice development papers to achieve this goal. We also propose the use of a corpus construction support tool. To speed up the construction process, we propose an approach...
A new Physical Unclonable Function (PUF) technology is proposed. The technology is targeting the implementation of a highly secure unclonable electromechanical device. The resulting system includes a physical unit providing identification properties mutually-dependent on both microelectronic and mechanical components. The technology is based on combining very high frequency wave propagation, scattering...
In order to ensure shipping enterprises' operating profit, the period of shipping operating evaluation and decision are usually understood as a key. This article applies the financial evaluation indicators of shipping operating management process to analysis the relationship between income and expenditure of shipping operation, moreover, the article combines shipping operating data of shipping enterprises...
There is many need and trial to find problem as one of processes for business and marketing. TRIZ-OTSM insists that a complex problematic situation is not a set composed of individual problems, but a network of problems according to their relationship. To find problem we analyzed two samples in informal and formal domains like Movie and Education. A sequence of finding problem is designing information...
Lifelong learning is matter to knowledge society and Academic Recommendation is necessary to feed learners with the relevant and personalized contents. E-commerce recommendation system has made great successful in book suggestion, like Amazon. But these techniques are still not adapted to academic domain. Our study has found 4 factors, including learner's academic intention, social network, learning...
The present study investigates Chinese EFL (English as a Foreign Language) learners' intonation pattern of exclamatory sentences. The results show that both Chinese EFL learners and English RP speakers (Received Pronunciation) adopt a falling (H*L) tone of a sentence to realize the exclamatory intonation. However, before the last H*L in an intonational phrase, a rising tone and the pitch contour enlargement...
The extraction and analysis of useful information from old document images is very important into cultural heritage preservation. In advanced research, where the goal is to separate the foreground (in general, text) from the background, image restoration and pattern classification techniques are used. Most of these methods consist of classifying the pixels based on their gray-scale value. In this...
The paper proposes a method of social tension detection and intention recognition based on natural language analysis of social networks, forums, blogs and news comments. Our approach combines natural language syntax and semantics analysis with statistical processing to identify possible indicators of social tension. The universal components of our method incorporate the general laws of natural language,...
We observed the level of lowering blood pressure (BP) and heart rate (HR) of SHR by total falconoid from Jumi. We used SHR models, intervene them by total falconoid from Jumi, and rats were divided into SHR control groups, nifedipine control group, total falconoid high dose groups, total falconoid medium dose groups and total falconoid low dose groups. We observed the level of Bp and HR by non-invasive...
This paper analyzes the method and techniques of extracting material information from engineer drawings and establishing product structure. In order to deal with the materials which don't have material code in the drawing, we build a statistics model based on materials being collected. We can gather the material list by making a medium template, and then integrate the CAD and ERP system with the information...
Acupuncture is an important component in traditional Chinese medicine. It is efficient in dealing with some diseases, esp. periarthritis of shoulder. In this paper, focused on periarthritis of shoulder, we mined the data set of literature with data slicing algorithm. Acupoints are calculated on two dimensions. The one-dimension calculates the frequencies of acupuncture points existed in literature...
Web data mining is a burgeoning technique of data analysis. This paper illustrates the relative theory of web data mining, points out the application feasibility of web data mining technology in the formulation of book purchase plans, and proposes book purchase strategy based on web data mining.
An important question is how to determine if a person is exhibiting suicidal tendencies in behavior, speech, or writing. This paper demonstrates a method of analyzing written material to determine whether or not a person is suicidal. The method involves an analysis of word frequencies that are used in a fuzzy cognitive map. The fuzzy cognitive map determines if there are suicidal tendencies. The method...
Foodborne pathogens such as Salmonella can cause gastrointestinal illness if they are ingested with uncooked foods such as salad. Foods such as salad pose a greater risk because they are consumed raw and have been the source of major outbreaks of disease from fresh produce. SipA, one of Salmonella's effectors, is an actin-binding protein that is required for its efficient entry into host cells. We...
Using data mining's decision tree classification, DBSCN cluster analysis, and K-nearest neighbor algorithm realizes the information mining of natural gas pipeline leak, and alse uncovers the objective laws behind the natural gas pipeline transmission, intrinsically linking to the each parameter and development trend. We could reduce the risk of accidents and economic losses, in order to control the...
With analysis on the current research status, this article studies on the dynamic subsidence principles of overburden rock strata during coal mining based on similar material simulation test. Close ranged industrial photogram metric system was introduced to collect data. After coordinate transformation, matching and model amendment, dynamic subsidence curves which can be used to analyze the continuity...
Debris flow has features of sudden outbreak and strong destruction. This article applies the rough set among the debris flow hazard assessment, through the attribute reduction, value reduction, extraction of decision rules, get the result of debris flow hazard assessment. Experiments show that this method is simple, efficient.
Equivalent Material Model is used to simulate the strata and ground surface movement which is caused by coal resources extraction from underground. This paper analyses the research status of deformation monitoring on equivalent material model, proposes a solution of monitoring the model. In the paper, photographic surveying of industry is use to monitor the movements of the target points which are...
The form-noticing language learners show in the language output and feedback is the key to improving the quality of output. While form-noticing has been increasingly researched by many language teachers, effects of proficiency and sex and its impact on subsequent learning in the context of EFL writing have not been fully investigated through data mining. This study examined EFL students' English vocabulary...
