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.

Abstract

Implementation of the PageRank algorithm to rank web generally only contain static and dynamic pages, with the rapid url users then needed an algorithm for calculating web rankings. In determining the ranking of a web, links incoming and outgoing links are also random surfer model is one decisive factor in determining the ranking of a web. Implementation of PageRank on MATLAB formed on a program in the m-file.

Abstract

The effect of social networking on business marketing strategies becomes inevitable. Taking a step back, we try to combine and analyze the effect on new product development and then propose a model for designing product deployment through social networks. We construct the issue of preferred stock (Kohli and Krishnamurti 1987), which is a common combinatorial optimization problem used as one of the methods for analyzing aggregated data analysis by marketers to identify products with the largest market share, and showing how to combine social networking securities in the issue of stock options .

Abstract

Granting scholarships to students aims to assist students in conducting lectures. Distribution of scholarships conducted by Muslim University Nusantara Al-Washliyah to help underprivileged or underachievers during their study The problem aims to choose some best alternative based on some attributes (criteria) used. In order to make decisions on fuzzy issues can be used Fuzzy Multiple AttributeDecision Making (FMADM). In this research modeling using Unified Modeling Language (UML) in FMADM with TOPSIS method and Weighted Product to select candidates of scholarship recipients.

Abstract

Queue is one of the phenomena that occur in everyday activities experienced by everyone. As a result of this queue many people turn to other places to avoid a queue and get more leverage. The purpose of this study is to study the performance of the queue system by modeling a single queue simulation. From the analysis of distribution test calculation will be obtained by queuing model. The measured system parameters are expected average speed velocity, average service speed expectation, chance of busy period, probability of all patient service in system, expectation of queue length, expectation of waiting time in system, and waiting expectation in queue.Keywords: distribution test, queuing model, and system parameters

Abstract

Research on zeolite processing as a reinforcement material is done to utilize natural resources in North Sumatera Province. Zeolite processing is so nanometer-sized by using a ballmill. Activation of zeolite is done by heating 1050 C for 10 minutes. The resulting zeolite particle size is 290 nanometers. It is obtained from 80 grams of zeolite measuring 1700 nanometers to 15 grams measuring 290 nanometers for 34 hours of grinding process in the ballmill.
