This algorithm combines the nonsubsampled contourlet transform and the mathematical morphology. First, the source image is decomposed by the nonsubsampled contourlet transform into multi-scale and multi-directional subbands. Then the edges in the high-frequency and low-frequency sub-bands are respectively extracted by the dualthreshold modulus maxima method and the mathematical morphology operator. Finally, the edges from the high- frequency and low-frequency sub-bands are integrated to the edges of the source image, which are refined, and isolated points are excluded to achieve the edges of the source image. The simulation results show that the proposed algorithm can effectively suppress noise, eliminate pseudo-edges and overcome the adverse effects caused by uneven illumination to a certain extent. Compared with the traditional methods such as LoG, Sobel, and Carmy operators and the modulus maxima algorithm, the proposed method can maintain sufficient positioning accuracy and edge details, and it can also make an improvement in the completeness, smoothness and clearness of the outline.展开更多

And now the integration of the mathematical culture in the university teaching is the effective method to improve the timeliness of the teaching and the enthusiasm of the students, and it also can effectively alleviate the problem of the disconnection in the university mathematical teaching, with the successful implementation of the transition. The university mathematics has very high demands in the teaching contents, the teaching ideas and the teaching methods, so the reasonable integration of the mathematical culture into the university mathematics is very important. The mathematical culture in the teaching of college mathematics is discussed and analyzed in this paper.展开更多

More importantly, mathematical skills are necessary when successfully completing mathematics- and/or science-based degrees. Social sciences such as psychology and economics require statistical skills which also require knowledge of mathematics. Even business students, such as marketing and accounting students need the necessary mathematical skills to successfully complete their degrees at university. This paper suggests that student success in a core business subject is dependent on their mathematical aptitude, attitude, and type of secondary schooling whether government or non-government schools. There is urgency for universities to recognize that high failure rates are due to insufficient mathematics exposure in secondary schooling and remedial classes might not be enough. Specifying a minimum (maths, e.g., two units) requirement for entry and/or providing bridging programs to ensure students have the necessary basic mathematical skills would increase student success in quantitative units.展开更多

Algebra 11 (2001) 5033]. The algebra U =Uq(sl2) is obtained from Uq(sl2) by adjoining a collection of orthogonal idempotents 1λ,λ ∈ P, in which P is the weight lattice of Uq(sl2). Under such construction the algebra U is decomposed into a direct sum λ∈p 1λ,U1λ. We set the collection of λ∈ P as the objects of the category U, 1-morphisms from λ to λ′ are given by 1λ,U1λ, and 2-morphisms are constructed by some semilinear form defined on U. Hence we get a 2-category u from the algebra Uq(sl2).展开更多

Some transitioned from face-to-face instruction to online instruction. The aim of this study is to investigate the perceptions of both the instructors and the students as regards second language acquisition through online education at a rural university. The study was implemented in the context of teaching and learning English as a second language in an online education environment. The course material is based on The Net Languages Learning Platform, which is available at http://ide.yok.gov.tr/, and the course level is general English pre-elementary. Both quantitative and qualitative methods were used in this study. For quantitative data collection, a questionnaire was employed to understand the reasons for low student attendance on online courses. For qualitative research method, observation was carried out, and interviews are designed as data collection techniques. Purposive selection was used for selection of the participants. The findings revealed that online education needs to be modified. The students are eager to improve their second language competencies; however, they do not want to waste their time on an easy course level.展开更多

The Phase equilibrium constants and lumped mass transfer coefficients of sugar and reducing sugar adsorption on D1, D2 and D3 resins as well as the axial dispersion coefficients of the fluid through packed columns are determined by means of the pulse-response experiment technique with an inert substance as a tracer and the chromatography measuring technique. The elution curve calculated from these parameters is good agreement with the experimental elution curve. The sensitivity analysis of these parameters is carried out, and the ressult shows that the elation curves of chromatography separation are more sensitive to the variations Of the Phase equilibrium relationship than to the variation of the axial dispersion as well as the lumped mass transfer coefficients.展开更多

Curricula also advocate an approach that allows student to understand the concepts involved supported by dynamical computer tools. However, there is not much research work joining these paradigms. Therefore, a case study was developed, with 9th grade students (14-15 years old), to evaluate the impact of a creative approach to isometries and symmetries-friezes, rosaceas (rosettes) and wallpapers-centered in patterns (reproduction, continuation, completion, description and creation) and using Geometer's Sketchpad software to solve, mainly in pairs, and discuss, with the whole class, the challenging tasks proposed, involving the formulation of hypothesis, argumentation and justification of the reasoning. The statistical analysis of the quantifiable data and content analysis of the qualitative data, collecting trough enquiry, direct observation and documental analysis (involving questionnaires, field notes, logbook, pre-tests and post-test, other works of the students including those computer related, and internal documents of the school) enable to conclude positively regarding the main research question underlying the study. In fact, it led to the conclusion that the teaching strategy implemented has contributed to deepen the student's knowledge and skills on geometry, mathematical communication and autonomy as well as to develop a closer relation with the field of geometry itself. This article focuses on one of the cases studied. The pair was selected due to be representative of most students and due to their communication skills.展开更多

However, it is believed that undergraduate accounting students with majors in mathematics from pre-university institutes perform much better than those with arts or social sciences backgrounds. Therefore, this paper~ takes the mathematics perception level as well as pre-university's cumulative grade point averages (CGPAs) as the main indicators of efficiency and better performance of undergraduate accounting students. In order to test the hypotheses, a multiple regression analysis has been used. By choosing all undergraduate accounting candidates, who had been admitted for academic calendars of 2009-2010 in four different universities (one public, two semi-publics, and one private university) and testing their mathematics excellency, as well as extracting their CGPAs, the authors find that students' mathematical talents are high, and to a lower extent, the CGPAs will positively influence the performance in accounting courses.展开更多

Interviews and classroom observation were used to collect data. After coding and recoding of the audio data, the researcher found that College English teachers face the following difficulties: positioning of themselves, commitment to the course, students' expectation, the balance between language and content, and administrative support. Meanwhile, the experience of teaching content-based courses offered them an opportunity to increase their knowledge of the content, the learners, and educational values. Some implications for CBI (content-based instruction) in curriculum reform were put forward at the end of the paper.展开更多
