Research ArticleOpen accessIn the abstractDelay Analysis and System Capacity Control for Mobile WiMAX Relay NetworksAnas F. Bayan, Tat-Chee Wan, Sureswaran RamadassProblem statement: WiMAX relay is an emerging cost effective wireless last mile solution for rural and urban broadband Internet access. Approach: One of the key concerns of WiMAX operators is how many users they can support for an access area where the number of users and the amount of data that can be delivered to the end user depends on … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Fully Coupled Approach for Evaluation of Wellbore Stability in Hydrocarbon ReservoirsVera RoccaProblem statement: When a well is drilled in a hydrocarbon reservoir, the original thermodynamic conditions are altered, the natural stresses are redistributed and a stress concentration occurs around the hole. The alteration of the original equilibrium can lead to wellbore damage, sometimes to its complete collapse. Loss of time associated with stability problems is estimated to account for 12-15% of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,559 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow to Guide and Assess Risk Reduction using Risk Characterization IndicatorsPeter Borgen Sørensen, Rainer Brüggemann, Marianne Thomsen et al.Problem statement: The risk level predictions in risk assessment often suffer from uncertainties and may, thus, overlook some adverse effects. This problem can be reduced by using risk reduction strategies that continuously guide activities toward lowest possible risk. Approach: This study suggested a method to guide and assess such risk reduction strategies using multi-indicator risk characterization. It was a challenge … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractRe-quantization Codebook Using FingerprintZ. F. Muhsen, M. A. Dababna, A. A. NsourRe-quantization is a key technology for reducing the bit rate of compressed data. The reduction of the bit rate and in certain cases may result in signal quality degradation. Techniques need to be deployed to enhance the signal quality based on optimization techniques. The proposed scheme constructed an optimal re-quantization codebook in an iterative manner for a given original quantization … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Quality of Homeland Security and Health Care Systems: The Texas Rangers InitiativeEldo E. Frezza, Maurizio Chiriva-InternatiHealthcare facilities are an essential component of an emergency response system in case of nuclear, biological or chemical attack, but at the present time, are poorly prepared for an incident. Key elements of the healthcare facility response plan include prompt recognition of the incident, staff and facility protection, patient decontamination and triage, medical therapy, and coordination with external emergency response … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtensive Analysis on Images Encryption using Hybrid Elliptic Curve Cryptosystem and Hill CipherSaniah Sulaiman, Zurina Mohd HanapiThe advancement of communication technology helps individual to share images through an Internet. However, the sharing through insecure channels may expose the images to certain attacks that will compromise their confidentiality. Image encryption is one of the methods used to protect against the confidentiality threat. A Hill Cipher has been applied in image encryption because of its simple operation and … …Journal of Computer Science, Vol. 17, Issue 3 · 2 Apr 2021 · 6,615 accessesView PDFCite
