The so-called ‘least squares regression’ for mathematical modelling is a widely used technique. It’s so common that one might think nothing could be improved to the algorithm anymore. But it can. By searching the ‘least squares’ not just in the vertical direction The first test results are very promising, and especially for power functions, often used in biomedical sciences, the conclusions you make from your data can change dramatically. Fermat prime exist up to1050.
数学建模中所谓的“最小二乘回归”是一种广泛使用的技术。它是如此普遍,以至于人们可能会认为算法已经没有什么可以改进的了。但它可以。通过搜索“最小二乘”,而不仅仅是在垂直方向上,第一个测试结果非常有希望,特别是对于经常用于生物医学科学的幂函数,您从数据中得出的结论可能会发生巨大变化。费马素数存在到1050。

Abstract. In this research the inverse Stefan problem in spherical model where heat flux has to be determined is considered. This work is continuing of our research in electrical engineering that when heat flux passes through one material to the another material at the point where they contact heat distribution process takes the place. At free boundary α (t) contact spot starts to boiling and at β (t) stars to melting and there appear two phase: liquid phase and solid phase. Our aim to calculate temperature in liquid and solid phase, then find heat flux entering into contact spot. The exact solution of problem represented in linear combination of series for radial heat polynomials and integral error functions. The recurrent formulas for determine unknown coefficients are represented. The effectiveness of method is checked by test problem and approximate problem in which exact solution and approximate solution of heat flux is compared. The coefficients of heat at liquid and solid phases and heat flux are found. The heat flux equation is checked by testing problem by using Mathcad program.Key words: Stefan problem, radial heat polynomials, Faa-di Bruno, collocation method.
摘要本文研究了球面模型中需要确定热流密度的反Stefan问题。这项工作是我们在电气工程方面的研究的继续,当热流通过一种材料到另一种材料时,在它们接触的地方,热量分布过程发生了变化。在自由边界α (t)处接触点开始沸腾,在β (t)处接触点开始熔化,出现液相和固相两相。我们的目的是计算液相和固相的温度,从而求出进入接触点的热流密度。径向热多项式与误差积分函数线性组合问题的精确解。给出了确定未知系数的递推公式。通过测试问题和近似问题,比较了热流密度的精确解和近似解,验证了方法的有效性。求得了液固两相的热系数和热流密度。利用Mathcad程序通过测试问题对热流方程进行了验证。关键词:Stefan问题,径向热多项式,Faa-di Bruno,配置法

Formative assessment is ideal for improving teaching and learning processes. However, little is practiced systematically and a traditional approach still persists in many educational institutions that value the product rather than the process. The objective of this study is to determine the evaluative process associated with multiple intelligences in high school students from an Educational Unit in the city of Manta. Methodologically, this research project is of a mixed type with a qualitative-quantitative approach since it obtains real data that evaluates the results. To collect the information, information from primary sources will be used and will be carried out through a survey via Google to teachers and secondary information will be taken from accredited sources of virtual libraries, indexed magazines, and other academic Google publications. The results will be processed using statistical methods that will allow their analysis and interpretation. As a result of it, a set of formative evaluation activities underlying the pedagogical practice of the teacher was obtained, assessing the general process of formative evaluation of learning included in the teaching-learning processes. The process is useful for conducting a conscious and systematic formative assessment.
形成性评估是改善教与学过程的理想方法。然而,很少有系统的实践,许多教育机构仍然坚持传统的方法,重视产品而不是过程。本研究的目的在于确定曼塔市某教育单位中学生多元智能的评估过程。在方法上,本研究项目是一种混合类型的定性和定量方法,因为它获得了评估结果的真实数据。为了收集信息,将使用来自主要来源的信息,并将通过谷歌对教师进行调查,次要信息将从虚拟图书馆,索引杂志和其他学术谷歌出版物的认可来源中获取。结果将使用统计方法进行处理,以便对其进行分析和解释。因此,我们获得了一套形成性评价活动,这些活动是教师教学实践的基础,评估了教学过程中学习的形成性评价的一般过程。这个过程对于进行有意识和系统的形成性评估是有用的。
