The need to improve learning outcomes in class VII students of Al Washliyah Middle School, then a model is sought that encourages like mathematics, motivate learn independently, and encourage have curiosity, involve active learning, both mentally , physical, or social. Therefore teacher must be able understand the cognitive style students. This because ability people processing information each...

Mathematics, the only subject, which is used in every sphere of our lives. However, it can’t be learnt overnight. Understanding and practicing mathematics regularly helps to make a firm base. Though it is a fascinating subject, but a very large fraction of students find the subject creepy. Such problems may crop up as a result of improper guidance in their initial stages. This paper is an attem...

The paper studies the use of discriminative techniques for a telephone based isolated digit recognizer with respect to a reduced system complexity. The combination of Linear Discriminant Analysis (LDA) and Minimum Error Classication (MEC) training provides improved system performance at reduced costs for the training process and for the application. Experiments are performed on an isolated digi...

Using the techniques of reverse mathematics, we characterize subsets X ⊆ [0, 1] in terms of the strength of HB(X), the Heine-Borel Theorem for the subset. We introduce W(X), formalizing the notion that the Heine-Borel Theorem for X is weak, and S(X), formalizing the notion that the theorem is strong. Using these, we can prove the following three results: RCA0 `W(X)→ HB(X), RCA0 ` S(X)→ (HB(X)→W...

Intracellular transport in eukarya is attributed to motor proteins that transduce chemical energy into directed mechanical energy. This suggests that, in nonequilibrium systems, fluctuations may be oriented or organized to do work. Here we seek to understand how this is manifested by quantitative mathematical portrayals of these systems. 1991 Mathematics Subject Classification. 34D23,35K50,92C3...

China Abstract In this article, we investigate the existence of infinitely many periodic solutions for some nonautonomous second-order differential systems with p(t)-Laplacian. Some multiplicity results are obtained using critical point theory. 2...

We give a new proof of the complete integrability of the geodesic flow on the ellipsoid (in Euclidean, spherical or hyperbolic space). The proof is based on the construction of a metric on the ellipsoid whose non-parameterized geodesics coincide with those of the standard metric. This new metric is induced by the hyperbolic metric inside the ellipsoid (Klein’s model). Mathematics Subject Classi...

It is rare to succeed in getting mathematics into ordinary conversation without meeting all kinds of reservations. In order to raise public awareness of mathematics effectively, it is necessary to modify such attitudes. In this paper, we point to some possible topics for general mathematical conversation. 2000 Mathematics Subject Classification: 00A05, 00A80, 97B20.

Computer-assisted methods have become very important in analyzing biosequence data. However, most of the current methods are limited to nding motifs only. Genes can be regulated in many ways, including combinations of regulatory elements. This research is aimed at combinatorial motif analysis and hypothesis generation. A genome-wide gene expression analysis demonstrated the value of the studies...

Using the techniques of reverse mathematics, we analyze the logical strength of statements similar to trichotomy and dichotomy for sequences of reals. Capitalizing on the connection between sequential statements and constructivity, we find computable restrictions of the statements for sequences and constructive restrictions of the original principles. 2010 Mathematics Subject Classification 03B...
