Research ArticleOpen accessIn the author namesThermo-Acoustic Water Analyzer in Hydrocarbon Emulsions with Kalman FilterMohammad A. Al-Khedher, Tariq M. Younes, Mohammad A.K. AliaProblem statement: Water detection in hydrocarbon emulsions represents a serious challenge in petroleum production industry. The elemenation of measurment noises is also desired. Approach: In this study, a systematic and an applicable method of water detection in hydrocarbon emulsion is achieved using thermoacoustic effect. A Kalman filter is applied to correct measurement errors and to improve accuracy. Results: The study … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 6 Mar 2012 · 7,316 accessesView PDFCite
Research ArticleOpen accessIn the author namesGroup Re-keying Protocol Based on Modular Polynomial Arithmetic Over Galois Field GF(2n)Sundaram Sudha, Azman Samsudin, Mohammad Ahmad AliaProblem statement: In this study we propose a group re-keying protocol based on modular polynomial arithmetic over Galois Field GF(2n). Common secure group communications requires encryption/decryption for group re-keying process, especially when a group member is leaving the group. Approach: This study proposes secret keys multiplication protocol based on modular polynomial arithmetic (SKMP), which eliminates the need for the encryption/decryption … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,165 accessesView PDFCite
Research ArticleOpen accessIn the author namesFractal (Mandelbrot and Julia) Zero-Knowledge Proof of IdentityMohammad Ahmad Alia, Azman Bin SamsudinWe proposed a new zero-knowledge proof of identity protocol based on Mandelbrot and Julia Fractal sets. The Fractal based zero-knowledge protocol was possible because of the intrinsic connection between the Mandelbrot and Julia Fractal sets. In the proposed protocol, the private key was used as an input parameter for Mandelbrot Fractal function to generate the corresponding public key. Julia Fractal … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the author namesA New Digital Signature Scheme Based on Mandelbrot and Julia Fractal SetsMohammad Ahmad Alia, Azman Bin SamsudinThis paper describes a new cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Having fractal based digital signature scheme is possible due to the strong connection between the Mandelbrot and Julia fractal sets. The link between the two fractal sets used for the conversion of the private key to the public key. Mandelbrot fractal function takes the … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the author namesCustom Design of an Analogue Input Digital Output Interface Card for Small Size PLCsMohammad A.K. AliaThis paper describes the design and implementation of an interface card (IC) with analogue input and digital output, designed for use with small size PLCs, which do not support interface features. The absence of generic I/O interface modules due to the differences in PLCs design and software, validates the importance of such work. The IC costs about one third of … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,442 accessesView PDFCite
Research ArticleOpen accessIn the author namesUsing PLC for Custom-design of a PID/PWM Program to Control a Heater TemperatureMohammad A.K. AliaThis is a practical approach to control a continuous-time process variable (temperature) using a discrete controller (PLC) and a custom-designed software control algorithm and hardware interface, in a closed-loop system. Unlike the conventionally known technique of transforming a digital control action into a proportional analogue one by a D/A converter followed by power amplifier, the control action was formed internally … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,662 accessesView PDFCite
Research ArticleOpen accessIn the author namesInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Role of a Combination of Autogenous Fresh Bone Marrow and Omental Free Graft in the Cervical Esophageal Wound Healing in DogsOmid Azari, Mohammad Mahdi Molaei, Reza Kheirandish, Sara Hamzeh AliabadProblem statement: Esophageal surgery is associated with greater wound healing problems than surgery on other portion of the alimentary tract. Omentum and fresh bone marrow are rich source of angiogenic factors that promote the growth of blood vessels into wound tissue. The aim of this study was evaluation of the effects of a combination of autogenous fresh bone marrow and … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,770 accessesView PDFCite
