The thesis researches and builds an entity search technique based on implicit semantic relations using clustering methods to improve search efficiency. Apply context-aware techniques, build an vertical search engine that applies context-aware in its own knowledge base domain (aviation data). Propose to measure combinatorial similarity in the contextual query suggestion problem to improve the quality of suggestion.

Trong bối cảnh đổi mới giáo dục ở Việt Nam hiện nay, vấn đề đào tạo các giáo viên có đủ kiến thức, kĩ năng và năng lực sư phạm là hết sức quan trọng. Nghiên cứu này làm rõ mô hình Kiến thức toán để dạy học đã được phát triển bởi các nhà nghiên cứu từ trường Đại học Michigan, Hoa Kỳ (Ball, Thames, & Phelps, 2008). Từ đó đề xuất quy trình để nâng cao và đánh giá các loại kiến thức này cho sinh viên ngành sư phạm toán trong các cơ sở đào tạo giáo viên ở Việt Nam.

Econometrics (economic measure) can be defined as a social science in which economic and mathematical knowledge are co-present in the analysis of economic phenomena. Knowledge already taught in secondary mathematics education must be transformed into tools for modeling phenomena of economic in reality. In this paper, we are going to explain the difficulties of students when they have to mobilize the two objects of knowledge: The slope of the straight line and the logarithms.

The control properties of biochemical pathways can be described by control coefficients and elasticities, as defined in the framework of metabolic control analysis. The determination of these parameters using the traditional metabolic control analysis relationships is, however, lim-ited by experimental difficulties (e.g. realizing and meas-uring small changes in biological systems) and lack of appropriate mathematical procedures (e.g. when the more practical large changes are made).

In this paper we improve an earlier result by Bukhgeim and Uhlmann [1], by showing that in dimension n ≥ 3, the knowledge of the Cauchy data for the Schr¨dinger equation measured on possibly very small subsets of the o boundary determines uniquely the potential. We follow the general strategy of [1] but use a richer set of solutions to the Dirichlet problem. This implies a similar result for the problem of Electrical Impedance Tomography which consists in determining the conductivity of a body by making voltage and current measurements at the boundary. ...

Digital signal processing has revolutionized the storage and transmission of audio and video signals as well as still images, in consumer electronics and in more scientific settings (such as medical imaging). The main advantage of digital signal processing is its robustness: although all the operations have to be implemented with, of necessity, not quite ideal hardware, the a priori knowledge that all correct outcomes must lie in a very restricted set of well-separated numbers makes it possible to recover them by rounding off appropriately. ...

Researches on deductive database systems are not new ones, but propose of data model allowing manipulating data and knowledge on a particular framework is not easy but interesting goal. The paper aims at a model for knowledge in educational and training environment, beside of a presenting the achievement in the existing systems concerning knowledge. Certain data manipulation techniques for knowledge acquisition are proposed in the model, as knowledge discovering techniques in deductive database systems. ...

In 1991, David Gale and Raphael Robinson, building on explorations carried out by Michael Somos in the 1980s, introduced a three-parameter family of rational recurrence relations, each of which (with suitable initial conditions) appeared to give rise to a sequence of integers, even though a priori the recurrence might produce non-integral rational numbers. Throughout the '90s, proofs of integrality were known only for individual special cases. In the early '00s, Sergey Fomin and Andrei Zelevinsky proved Gale and Robinson's integrality conjecture.

Spectral extrema for graphs: the Zarankiewicz problem L´szl´ Babai∗ a o Barry Guiduli†Submitted: Jul 12, 2007; Accepted: Sep 21, 2009; Published: Sep 25, 2009 Abstract Let G be a graph on n vertices with spectral radius λ (this is the largest eigenvalue of the adjacency matrix of G). We show that if G does not contain the complete bipartite graph Kt,s as a subgraph, where 2 t s, then λ (s − 1)1/t + o(1) n1−1/t for fixed t and s while n → ∞. Asymptotically, this bound matches the K˝v´rio a Tur´n-S´s upper bound on the average degree of G...
