Research ArticleOpen accessEvery word in the titleDeveloping an Effective Churn Prediction Model for Telecommunications: Enhancing Customer Retention through Advanced Machine Learning TechniquesAshu Goyal, Anuj Gupta, Sharad Kumar et al.Customer churn poses a significant challenge for the telecommunications sector, resulting in substantial revenue losses and increased customer acquisition costs. This research creates an efficient churn prediction model that combines state-of-the-art machine learning with ensemble learning to maximize customer retention. With the IBM Telco Customer Churn dataset, several baseline models, including Gradient Boosting, AdaBoost, Logistic Regression, Random Forest, and Support … …Journal of Computer Science, Vol. 22, Issue 1 · 3 Feb 2026 · 3,164 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHorizontal Cooperation Practices in Internet-based Higher Education, Computational Logistics and TelecommunicationsJesica de Arma, Thanasis Daradoumis, Anastasios A. Economides, Angel A. JuanGlobalization and advances in information and communication technologies have boosted the use of Horizontal Cooperation (HC) practices in many industry sectors. In the current international market, these ‘alliances’ become especially relevant for small and medium organizations, which are forced to compete with large-scale corporations. This paper analyzes benefits and challenges of HC practices in three service sectors that are critical … …Journal of Computer Science, Vol. 15, Issue 1 · 31 Jan 2019 · 7,421 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegration of Quantum Cryptography through Satellite Networks TransmissionSkander Aris, Abderraouf Messai, Malek Benslama et al.Problem statement: The security of the telecommunications satellite has become a crucial issue. The telecommunications can be set using the classical cryptography. But this so-called classical cryptography provides cryptographic security. This means that security is based on the difficulty of some mathematics problems. On the other hand, quantum cryptography provides security without conditions based on the law of quantum physics. … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the keywordsScheme for ISDN/DECT Wireless Internetworking and VerificationMaher Dababneh, Ibrahim QatawnehA novel scheme to access the basic rate service of the Integrated Service Digital Network (ISDN) using the Digital Enhanced Cordless Telephone (DECT) radio interface standard is presented. The S-interface in the ISDN reference configuration has been used for the ISDN interface and the unprotected class 0 transmissions are used for the DECT interface. The design of a state of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThai Speech Coding Based On Conjugate-Structure Algebraic Code Excited Linear Prediction AlgorithmSuphattharachai ChomphanProblem statement: In mobile communication, speech coding aims at compressing the speech with lowest bitrate and highest quality for standard languages such as English, German and French. As for other languages with different uttering styles, the encoded speech quality is not guaranteed at the same bitrate. The appropriate evaluation should be performed to develop the speech quality by applying some … …Journal of Computer Science, Vol. 7, Issue 1 · 14 Jan 2011 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLow Cost Test Bench to Assess Energy Efficiency of Communications Network EquipmentLuiz Henrique Biazotto, Alexandre de Assis Mota, Lia Toledo Moreira MotaCommunication network Quality of Service (QoS) degradation can lead to the consumption of additional energy to exchange information than that needed in normal conditions. If such behavior is known, network management can be more efficient and accurate, permitting to control more efficiently the energy consumption in telecommunication equipments. This study describes a test bench that can simultaneously measure the QoS … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 6,678 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCache Management for Concurrent Transaction Execution in Mobile Wireless EnvironmentJ.C. Miraclin Joyce Pamila, K. ThanushkodiProblem statement: Improvement in mobile communication technology and increased capability of mobile devices has made transaction processing possible with mobile devices. Transactions access services provided by the data server connected to the packet data network. Direct data access may overload the network and server. Data items are cached to improve data availability. The cache should be managed and maintained effectively … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,809 accessesView PDFCite
