Calculating differntial and integral
Case study - 5 pages - Mathematics
The Differential and Integral Calculus "is the mathematics of change" (Larson, 1998 p.85). It is one of the most traditional disciplines in educational sciences at the university, and that has best preserved its original structure. It is important, and think why the fact that, even today, with...
A continuous manufacturing processes to manage the outgoing quality
Thesis - 6 pages - Mathematics
When the production is continuous and the process is not under statistical control (i.e., p is the probability of a defective unit is constant) and at the same time it does not follow a scheme of total control, it is remarked that a dependent process will be more realistic than the existing...
Heuristic algorithms for scheduling of a batch processor for the automobile gear manufacturing environment
Thesis - 18 pages - Mathematics
In this paper we develop a mathematical model and propose six heuristic algorithms for scheduling jobs with incompatible job families, on a singe batch processor (BP). The motivation for this paper comes from the heat treatment operation in gear manufacturing process used to manufacture...
Evaluate semi-supervised classification with collaborative learning algorithm
Thesis - 5 pages - Mathematics
Conventional classification models are built based on supervised learning which invariably requires class labels of entities to be classified along with their description. Even the instance based classifiers require class labels of their training examples to predict the class labels of unknown...
A recursive algorithm for parameter optimization in support vector regression
Thesis - 3 pages - Mathematics
Parameter Optimization is the most crucial task during any model development. The task becomes challenging when the model involves multiple parameters with interrelationships among them. This work concentrates on parameter optimization for Support Vector Regression of atmospheric variables....
Performance evaluation of texture features with co-occurrence and Q-matrix
Thesis - 2 pages - Mathematics
The Present paper compares the texture features based on co-occurrence and the new Matrix-method called “Qmatrix”, which measures the similarities of grey levels. The problem addressed is to determine which features optimize classification rate. Such features may be used in image...
Weight adapted of k - nearest neighbor algorithm with genetic approach implementing over data classification
Thesis - 6 pages - Mathematics
The enormous flow of information in various fields of technology prompts for the development of novel Data Mining methodologies that can process and interprets large volumes of data to be classified to a specify category with high reliability. The problem with Data Classification is inconvenient...
The use of genetic algorithm for solving a long-term land allocation problem for optimal cropping plan in agricultural system
Case study - 15 pages - Mathematics
This paper presents how the genetic algorithms (GAs) can be used to the fuzzy goal programming (FGP) formulation of land allocation problems for optimal production of seasonal crops in agricultural system. In the proposed approach, utilization of total available land for cultivation, aspiration...
Review of LMS algorithm and its implementation on TMS320C6713 DSK platform
Thesis - 5 pages - Mathematics
In this paper, we illustrate the use of adaptive algorithms to time varying conditions on the linear filter. We explain the Least Mean Square Algorithm which is based upon the stochastic gradient algorithm. Using this algorithm in SIMULINK on windows platform, we demonstrate the use of LMS...
Signature recognition by the algorithm of string matching
Thesis - 4 pages - Mathematics
This method generates string for the given original signature. Basically by using this method each image gets converted into a string. So the original signature which is input to the method, a string can be constructed. Now if we rotate this signature by 0 to 360 degrees then we will get 360...
Use of regression method of estimation for estimating mean from incomplete sample
