Abstract

Abstract. The effect of social networking on business marketing strategies becomes inevitable. Taking a step backward, we seek to combine and analyze such effects on new product development and then propose a model for designing product deployment through social networks. We construct a share of choice problem (Kohli and Krishnamurti, 1987), which is a combinatorial optimization problem used generally as one method to analyze conjoint analysis data by marketers to identify products with the largest market share and show how to combine social network effects in a share of choice problem.Keywords: Social Networks, Genetic Algorithm, Marketing.

Abstract

Study on the energy of a graph becomes a topic of great interest. One is the detour energy which is the sum of the absolute values of all eigenvalue of the detour matrix of a graph. Graphs obtained from a group also became a study that attracted the attention of many researchers. This article discusses the subgroup graph for several normal subgroups of dihedral groups. The discussion focused on the detour energy of complement of subgroup graph of dihedral group

Abstract

The geometry concept has been developed rapidly, one of them is about fractal geometry. In fractal geometry concept, it has been discussed about shapes which have fractal dimension characteristics. In fractal geometry concept, it would resulted in a look like irregular shape. But if it had been observed closer, it would found a regular shape. Self-similarity is a characteristic in fractal geometry when diferent magnifications was found. In fractal concept, a pattern would be obtained from a function itteration by an infinite repetition. One of fractal geometry application is in batik design fabrications. This idea based on equality dimension, that is both of them is in fractal dimension. In fractal geometry, it will result in a specific design by itterated function using Wolframs a program.

Abstract

This paper aimed to basic mathematical skills based to the studying approach. To this subject pre detection is a need. One way ANOVA analyzing will show the significant of basic mathematical skill of students by giving different studying approach. Hence, there is correlation within basic mathematical skill to studying approach. Teachers should be able measure basic mathematical by designing model supporting understanding level, critical thinking ability made concept. The sample consisted of all the second semester of mathematical students by random sampling. Approaches and Study Skills Inventory for Students (ASSIST) is used to studying approach, Bayesian Information Criterion (BIC) is used to create group classification. Two Step Cluster Analysis Method divided into three approaches (Strategies, Surface, Deep)

Abstract

Statistical pattern recognition is a system that aims to classify a number of objects to a number of categories or classes. Given a data matrix A, A = {Π1, Π2,…, Πk} where Πi consist of ni point data of ith class then patterns in each classes can classify and separate distance of within and between-class in datasets. In this paper, Symmetric Two-Dimensional Linear Discriminant Analysis proposed to maximize the between-class scatter matrices (Sb) and minimize the within-class scatter matrices (Sw), and can recognition the symmetric capital letter by hand writing such as A, B, C, D, E, H, I, K, M, O, S, U, V, W and Y by using ADL2-D algorithm.
