Research ArticleOpen accessIn the abstractKey Exchange Protocol in Elliptic Curve Cryptography with No Public PointK. Kaabneh, H. Al-BdourIn recent years some cryptographic algorithms have gained popularity due to properties that make them suitable for use in constrained environment like mobile information appliances, where computing resources and power availability are limited. One of these cryptosystems is Elliptic curve which requires less computational power, memory and communication bandwidth compared to other cryptosystem. This makes the elliptic curve cryptography to … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,067 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIntensity Position Modulation for Free-Space Laser Communication SystemF. Faghihi, A. JangjooIn this study a novel analog modulation-demodulation technique for free-space laser communication system called Intensity Position Modulation (IPM) is carried out. According to TEM00 mode of a laser beam and by linear fitting on the Gaussian function as an approximation, the variation of the linear part on the reverse biased pn photodiode produced various currents. Our simulated results show fine … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,601 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRetrieving Information from the Invisible Web Using Mobile AgentsFabien-Kenzo Sato, Samuel Pierre, Roch H. GlithoThis study proposes a model of information retrieval on the invisible Web by using the mobile agent paradigm. The developed architecture uses the power of a search engine to provide a list of sites of the invisible Web which are likely to be relevant and launches a dynamic search on these sites, thanks to mobile agents. To compare and experiment … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,839 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesigning of Child Growth Chart Based on Multi-Response Local Polynomial ModelingNur Chamidah, I. Nyoman Budiantara, Sony Sunaryo, Ismaini ZainProblem statements: Anthropometry measures used to measure physical children growth are not onlyweight but also height and head circumference. In this study we develop the estimation of multi-response localpolynomial regression and apply it to design growth chart for children up to five years old based on three responsevariables i.e., weight, height and head circumference. Approach: Based on local polynomial estimator, … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 4 Sep 2012 · 7,506 accessesView PDF Cite
