In molecular biology, phenotypes are often described using complex semantics and diverse biomedical expressions, thereby facilitating the development of named entity recognition (NER). Here, we propose a novel approach of recognizing plant phenotypes by cascading word embedding to sentence embedding with a class label enhancement. We utilized a word embedding method to find high-frequency phenotypes...
Industry 4.0 can make a factory smart by applying intelligent information processing approaches, communication systems, future-oriented techniques, and more. However, the high complexity, automation, and flexibility of an intelligent factory bring new challenges to reliability and safety. Industrial big data generated by multisource sensors, intercommunication within the system and external-related...
The paper presents results of studying the quality of extracting information from vibrating objects. A capability of getting information from vibrating objects situated at an arbitrary angle to the observer is investigated. Reliable extracting information from the test object situated within an angle of +/− 50 degrees relative to the plane perpendicular to an observer is demonstrated. A possibility...
Nowadays Micro-blog as a widely used medium platform, its diverse features meet the people's information, interpersonal information and other aspects of the new requirements. There are many research articles which explore and study the Micro-blogs, especially the English micro-blogging, i.e., twitter. However, Chinese micro-blog service starts rather late and a few research is about its data and characteristics...
Against the defect that the traditional computer network security management system processes a mass of data with low efficiency and accuracy, a novel network security management model based on data mining is proposed in this paper. It makes use of multi-source data collection strategy to acquisition and integrate the relevant data of different security products, and takes advantage of data mining...
According to the foreign research, small and medium-sized high-tech enterprises growth influence factors are get. Based on the large questionnaire investigation and using comparison analysis method, main factors that influence the growth of Dalian small and medium-sized high-tech enterprises is discussed. Through research, high-speed growth small and medium-sized high-tech enterprises and low-speed...
In this paper, based on the Lebesgue measure of level cutsets and the membership degree of an element in level cut-sets, we introduce the concept of level creditability of fuzzy numbers, present a necessary and sufficient condition of level creditability being equal to 1 for each ?? ?? [0,1], and then consider the basic properties (such as continuity, monotonicity etc.) of level creditability and...
A scheme that ATPG-based technique for reducing shift and capture power during scan testing is presented without any influence on fault coverage. This paper presents an X-filling approach called adjacent backtracing fill (AB-fill). After AB-fill approach for at-speed scan testing, all of test patterns have assigned as partially-specified values with a small number of don't care bits (x) as in test...
In this paper, a novel multifocus image fusion method based on region selection is proposed. The basic idea is to select sharply focused regions from source images and to combine them together to reconstruct the resultant image. Region Acutance as a kind of superior sharpness criterion is introduced here for region segmentation. In view of the inevitably errors of selection, morphological operations...
Agriculture is a pillar of industry and a key component of economy and society in most if not all of the countries of the world. Management of Technology (MOT), an emergent body of knowledge and techniques, can be effectively applied to improve economic efficiency of agriculture and develop a more harmonious relationship between agriculture and environment. MOT models, having found successful applications...
Let G(V, E) be a simple graph,k (1 les k les Delta + 1) is a positive integer, f is a mapping from V(G) upsi E(G) to {1, 2,..., k} such that foralluu, uw isin E(G), v ne w, f(uv) ne f(uw); foralluv isin E(G), if d(u) = d(v)then C(u) = C(v); we say that f is the adjacent vertex reducible edge-total coloring of G. The maximum number of k is called the adjacent vertex reducible edge-total chromatic number...
We present a new (differential) entropy estimator where the maximum entropy bound is used to approximate the entropy given the observations, and is computed using a numerical procedure. The resulting accurate estimate for the entropy is used to derive a new algorithm to perform independent component analysis (ICA). The new algorithm, ICA by entropy bound minimization (ICA-EBM), adopts a line search...
Lucene is currently and has been for a few years, the most popular free Java full-text retrieval library. Firstly, this article analyzes Lucence system structure, indexing mechanism, searching mechanism; secondly, it studies the sorting technology and how to adjust indexing performance; finally, the article presents a new retrieval sorting algorithm.
The paper proposes a novel method to determine sentence similarities. First two compared sentences are parsed by shallow-parsing and all noun phrases, verb phrases and preposition phrases of each sentence are extracted. Then the similarity between each kind of phrases is calculated based on a semantic vector method. The overall sentence similarity is defined as a combination of semantic similarities...
Geographic concept is spatial objects on or near the surface of the earth and they are typically complex. Semantic relation is an important problem in the description of concept. Attribute method is widely used to realize concepts' semantic representation in a great many subjects. According to the definition of geographic concept, we use ontology property to describe geographic concept instead of...
Based on the operating characteristics of pump load, the hydraulic speed regulation is widely used in the high-power pump load to realize the speed regulation and energy saving. This paper analyzes the energy saving features of the currently-adopted hydraulic speed regulation method in the high-power pump load and the inevitable power loss problems. According to the fundamental features of differential...
The multi-constraint conditions, including the entrance examination for college, the region and the dormitory classification and so on, were analyzed and studied enough by assigning management dormitory reasonably. A new backtracking algorithm based on matrix storage was proposed, and the realization detail of the algorithm was discussed. Further, the complexity of the algorithm was analyzed. The...
One key factor towards the success of software and service is the standardization of service protocols/languages and the interoperability among them. While SOAP (Simple Object Access Protocol) is one such protocol for service message, its heavy performance overhead is often a big concern, as compared to the light-weighted REST (Representational State Transfer) and HTTP protocols. In this paper, we...
In this study, large-area W18O49 pencil-like nanostructure arrays can be grown on silicon substrate by multi-step thermal evaporation process is demonstrated. A side view scanning electron micrograph of a typical W18O49 pencil-like nanostructure arrays (a) and the enlarged SEM image (b) of a nanotip, as well as their typical SAEDS spectrum (c) and typical XRD spectrum (d) is shown. The samples of...
