A Computational Model for Multi-level Quadratically Constrained Quadratic Optimization under Fully Fuzzy Environment
Fully fuzzy quadratic programming became emerge naturally in numerous real-world applications. Therefore, an effective model based on the bound and decomposition method and the separable programming method is proposed in this paper for solving Fully Fuzzy Multi-Level Quadratically Constrained Quadratic Programming (FFMLQCQP) problem, where the objective function and the constraints are quadratic, also all the coefficients and variables of both ...

Architecting Decision Support System for Allocating Budget at Egyptian Universities
The main objective of this study is to optimize the budget allocation process for various organizational units in the university. For that, university budget allocation system based on multi-level quadratic optimization model is suggested. The objective function of the proposed system is to minimize the sum of the quadratic deviations of each allocation from its lower and upper limits. The ... Read more

Using Image Mining Techniques For Optimizing The Treatment Methods Of Lung Cancer
Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. Lung cancer is the most critical reason for death, but there is a big chance for the patient to be cured if he or she is correctly diagnosed in early stage of his or her case. Medical chest images are considered the most widely used and ... Read more

An Interactive Model for Multi-Level Large Scale Quadratic Programming Problem Having Factorized Objective Function

2016 | Keywords bisection method, quadratic programming, large scale problem, multilevel programming, Decomposition algorithm,
An Interactive Model for Multi-Level Large Scale Quadratic Programming Problem Having Factorized Objective Function
The motivation behind this paper is to propose a new approach to reformulate the objective function based on the decomposition algorithm in an interactive model for finding the optimal solution to Multi-Level Large Scale Quadratic Programming Problem (MLLSQPP), in which the objective function can be factorized into two single linear objective functions and has block angular structure of the constraints. ...

TEXT MINING SYSTEM FOR FINDING AND PREDICTING GENES FROM BIOMEDICAL DOCUMENTS

2010 | Keywords text mining, biomedical literatures,
TEXT MINING SYSTEM FOR FINDING AND PREDICTING GENES FROM BIOMEDICAL DOCUMENTS
The number of biomedical literatures is growing rapidly; most of these literatures are available online in an unstructured textual format, such as in the PubMed online system which is a tremendously rich information source. Reading every available article is a time-consuming task in addition to the fact that researchers have to face information overload problem, and that the coverage of ... Read more
