Research ArticleOpen accessEvery word in the titleNetwork Data Envelopment Analysis Model for Estimating Efficiency and Productivity in UniversitiesMohammad Mahallati Rayeni, Faranak Hosseinzadeh SaljooghiProblem statement: The aim of this study was to compute disaggregate performance measures of universities. The traditional models for Data Envelopment Analysis (DEA) type performance measurement are based on thinking about production as a "black box". Inputs are transformed in this box into outputs. One of the drawbacks of these models is the neglect of linking activities. Approach: Network DEA … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,880 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficiency Decomposition with Enhancing Russell Measure in Data Envelopment AnalysisTien-Hui Chen, Chiao-Pin Bao, Chi-Ming Huang, I-Chiang WangProblem statement: Most studies about the application of Data Envelopment Analysis (DEA) follow the concept of radial and non-radial efficiency measures. Because of some difficulties with the measure of weights, Russell measure utilizes the mean of all input/output efficiency measurements as the efficiency score of a specific business unit. However, this may render bias. Approach: This study provided a reasonable … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,051 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of the Prospects for Developing Storage and Processing Complexes for Multiformat Media DataVladimir Zhanovich Kuklin, Islam Alexandrovich Alexandrov, Alexander Alexandrovich Umyskov, Abas Khasanovich LampezhevA distinctive feature of multifunctional systems for supporting multimedia services on a single platform is the heterogeneity of incoming streams and requests, which requires optimization of resource use under physical constraints. In this regard, it is relevant to develop promising proposals for the functional structure and technical characteristics of complexes for storing and processing multi-format media data, which was the … …Journal of Computer Science, Vol. 18, Issue 12 · 6 Dec 2022 · 5,577 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE LINEAR PROGRAMMING APPROACH ON A-P SUPER-EFFICIENCY DATA ENVELOPMENT ANALYSIS MODEL OF INFEASIBILITY OF SOLVING MODELChiao-Ping Bao, Chen-Hu Jeng, Ching-Chung Guey, Chien-Liang LinThe traditional CCR or BCC model in DEA for DMU assessment often come out with multiple efficiency units, which cause problems in rank ordering. Therefore, we intended to improve level of discrimination among Decision Making Units (DMUs). The present study thus seeks to solve the above-mentioned problems of discrimination and infeasible solutions in A-P super-efficient mode by proposing a feasible … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 3 Feb 2014 · 6,839 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Big Data Football Club Market Value Using K-Means and Linear Regression Mining MethodsJohanes Fernandes Andry, Riama Sibarani, Vlavio Nathanael YeftaFootball clubs store a lot of data about their players, squad, transfer market, and market value, so big data is needed to process this data. This data can be analyzed to gain insight into the club's market value. Changes in player performance, age, and squad size can be analyzed using statistical methods. These digital data will provide information about the … …Journal of Computer Science, Vol. 19, Issue 2 · 10 Feb 2023 · 5,991 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Data Mining Driven Framework for Image-Based Crop Stress Analysis Using IPCA, FP-Growth, ConvLSTM, and Sequential ModelsA. Josephine, A. SubhashiniDetecting crop stress before it becomes serious has a major impact on the food supply. It helps in avoiding the loss of crops, increases productivity and helps farmers to practice precision farming. Most technologies today are designed specifically to either detect crop stress or to predict how well the crop will grow. Many of the technologies do not combine the … …Journal of Computer Science, Vol. 22, Issue 8 · 21 Aug 2026 · 922 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleData Warehouse Design to Support Social Media Analysis in a Big Data EnvironmentCarlos Roberto Valêncio, Luis Marcello Moraes Silva, William Tenório et al.The volume of generated and stored data from social media has increased in the last decade. Therefore, analyzing and understanding this kind of data can offer relevant information in different contexts and can assist researchers and companies in the decision-making process. However, the data are scattered in a large volume, come from different sources, with different formats and are rapidly … …Journal of Computer Science, Vol. 16, Issue 2 · 20 Feb 2020 · 8,223 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of Data Mining Classifiers on Sunflower Edible Oil Bleaching Process: A Comprehensive Comparative AnalysisÖmer Nedim Kenger, Eren ÖzceylanSunflower oil is widely used as edible oil. It is commonly extracted by solvent extraction method from the sunflower seed. After extraction, crude sunflower oil is obtained. Crude sunflower oil has some undesirable impurities and dark colors. These impurities and dark colors require removal. The bleaching process is applied to remove the color.
