Alignment-free sequence comparison methods can compute the similarity between a large number of sequences much faster than methods that depend on sequence alignment. We propose a new alignment-free sequence comparison method, called K2, based on the non-parametric Kendall statistic. Compared with the state-of-the-art alignment-free comparison methods (e.g., D2, D2*, D2sh, and Chisquare(χ2) statistic),...
This paper describes a work-in-progress to identify and categorize metaphorical language use in a large corpus of historical German novels. An unsupervised learning method is utilized to detect metaphorical expressions and underlying conceptual metaphors. Furthermore, an extension is proposed that allows for the analysis of diachronic developments of modeled metaphor types. A corpus ranging from the...
In geosteering drilling technology, the transmission of information measured by near-bit sensor has always been a problem. Downhole drilling tool is a very complex medium for sonic transmission. This paper takes geosteering drilling tool as the study object, and puts forward a method of short distance transmission, which is based on sonic wave transmission theory. The experiment testing the drilling...
With the rapid development and popularization of the Smartphone and mobile internet technology, Social Networking Service (SNS) has become extremely in favour over recent years. As we all known, one of the most world famous SNS, which we called Facebook, was once launched by Mark Zuckerberg and his college roommates in Harvard University. Although all platforms seem to emphasize the relationship properties...
Using the cone theory, the existence of fixed point for a class of nonlinear operators in Banach space are discussed, and new results on these operators are obtained. An application to the Hammerstein integral equations is given. The results presented here improve and generalize some known results.
Visualization experiments were conducted in a positive pressure system to investigate the starting process characteristics of the absorber sphere pneumatic conveying. The ambient air was used as the source gas. The absorber sphere was replaced by the glass sphere. Spouted spheres flow was observed at the early stage of the starting process. With the increase of feeder inlet gas flow rate with time...
In this paper, we discuss the moment problem of g-frames in Hilbert spaces. Firstly, we give the definition of moment problem which is based on operators, and discuss the necessary and sufficient conditions of the existence of its solution. Secondly, we discuss its best approximative solution by orthogonal projection when it has no exact solution.
Accurate measurement of air flow is important for safe and economical operation of power plant. The straight tube before and behind measurement instrument usually can not meet the demands because of the design and installation condition, which affect the measurement accuracy. Flow field, Pressure and velocity distribution of airflow duct with Fairing device is studied in this paper. The optimization...
The study aims to exam if there were significant differences among urban and rural elementary schools in the implementation of ICT education. The study focused on information technology curriculum. A questionnaire according to three dimensions (learning, instruction, surroundings of learning) was the measurement tool for the study. The target population was all 5th grade schools students from three...
Based on the project-learning and the constructivist learning theory, an experimental project teaching mode is proposed with the help of computer network technologies. It offers the students an autonomous and open-ended learning platform, as well as an independent study and teaching management combined environment. This mode stimulates the students' learning enthusiasm, improves their comprehensive...
Bootloader is a piece of code that runs before any operating system running. It is mainly to initialize hardware, boot the system, download programs into RAM, and so on. U-Boot is one of the most common and powerful Bootloader. Based on S3C2440 SOC, the paper analyzes the U-Boot start-up procedure, and introduces the method that presenting a command menu to select the command for the development board.
This The results, based on the methods of literature analysis, measurement comparison, sample survey, and practice in work, indicate that honesty and credit education of university students is a comprehensive process involving in the interplay between knowledge, emotion, conscious and behavior. Universities should set up a reasonable permanent mechanism for honesty and credit education of students,...
In this paper, A new model of interval Fuzzy cooperative games with Choquet integral form is given. The interval imputation and its monotonicity are studied in detail. When the interval fuzzy cooperative games with Choquet integral form are fuzzy convex, the form of the interval Shapley value is shown. Furthermore, the improved Shapley value was introduced in to the game. It has some values for the...
Enterprises have become increasingly dependent on online social network to carry out beneficial e-business model and achieve better performance. This paper aims to explain and demonstrate how an online social network environment where enterprise cooperative behaviors and interaction structures coevolve influence enterprise business model. By constructing components model of enterprise business model...
In recent years, global food, energy and environmental issues become increasingly prominent. Expansion of urban sprawl results in the “City Syndrome”, such as high population, industrial concentration, serious pollution and “heat island” effect escalation. It also brought a large number of species extinction, global environmental pollution and global climate change. China is in the stage of rapid...
Considering the poor accuracy of extension theory using in fault diagnosis field, a method of combining rough set and extension theory is presented. The method use historical test data firstly to construct the attribute sets and decision-making sets for fault diagnosis, then using rough sets reduce the attribute sets, and calculating the important degree of each condition attribute for decision-making...
The subjective evaluation of chassis handling and comfort, tuning activities and methods are introduced in this paper. Also the chassis tuning necessity and solution planning of tuning sample are described. Moreover, the main factors to adversely affect chassis handling and comfort are discussed. The chassis tuning can be performed by a combination of simulation and theoretical analysis.
As the acquaintance with the safety of structure is improved, the structure health monitoring play a more important role, in which damage identification is a key problem. In this paper, for reinforced concrete beams, β index and η index based on flexibility matrix are proposed to detect damage. Two RC beams with a span of 7m are tested and the proposed indexes are used to identify damages.
Nowadays the urbanization is accelerating, the water environment problem increasingly serious, especially the flood disaster, groundwater resources development and protection problems, seriously hindering the healthy and sustainable development of the city. This paper is based on the flood geological record which is since palaeoloxodon, put forward the view of urban flood control planning and construction,...
The article described the method of tool-angle virtual measurement under the environment of SolidWorks, which has the advantage of lower invest and preciser measurement. And this method has a high practical value which can be used to show the process before actual tests in practice and staff training in enterprise.
