This paper applies the artificial fish swarm algorithm (AFSA) to fuzzy clustering. An improved AFSA with adaptive Visual and adaptive step is proposed. AFSA enhances the performance of the fuzzy C-Means (FCM) algorithm. A computational experiment shows that AFSA improved FCM out performs both the conventional FCM algorithm and the Genetic Algorithm (GA)(More)
This article explains the design of an infrared-based human-machine interface using low cost components and infrared distance measuring sensors. This interface is targeted for people suffering from reduced mobility as well as specific professionals operating in constraining situations. This design allows using simple head movements to perform basic computer(More)
We present a comparative study of different Fiber-Wireless networks with regards to their applications, architecture, hardware complexity, development costs, offered services and allocated bandwidths. While spectral resources and high data-rates are incessantly requested, these radio over fiber (RoF) networks have been proposed to overcome limitation in(More)
Over the past decade there has been significant rising of the use of Voice-over-Internet-Protocol (VoIP) to reduce communication costs. This paper describes a VoIP based solution designed for the use over a campus environment taking in consideration context and architecture of computer networks: Local Area Network, Personal Area Network, Campus Area(More)
This paper applies a method to use the access log data to audit websites. It studies website auditing by (1) proposing a new fuzzy clustering algorithm that combines standard Fuzzy C-Means and the Artificial Fish Swarm Algorithm; (2) presenting a new measurement index for similarities between user sessions; and (3) providing an experiment on the execution(More)
In this paper, a new alignment method based on the particle swarm optimization (PSO) technique is presented. The PSO algorithm is used for locating the optimal coupling position with the highest optical power with three-degrees of freedom alignment. This algorithm gives an interesting results without a need to go thru the complex mathematical modeling of(More)
VoIP is replacing traditional telephony system over PSTN as a more affordable communication tool on account of convergence of networks. Meanwhile, security issue brings more attention and becomes more important. SIP is based on text message. This makes the protocol easy to implement but also creates opportunity for hackers to steal or modify the messages.(More)
Our global objective is to profit from the technology offered by the computer and/or Internet without being constrained by sitting in front of a computer. As an example of application, we present a method to use Voice over IP (VoIP) computer software remotely. This method targets mainly the population with reduced mobility or the population unfamiliar with(More)
In this paper, an optical fiber alignment system based on the particle swarm optimization (PSO) technique is developed and presented. The PSO algorithm is used for locating the optimal coupling position with the highest optical power with two-degrees of freedom alignment. This algorithm yields interesting results without a need to go through the complex(More)
The capacity of optical communication systems is rising exponentially in order to follow the rapidly increasing demand for data traffic. Limitations due to dispersion and non-linearity in the optical fiber become more stringent for higher bit rates. For the first time, to the best of our knowledge, this document illustrates a new optical technique to post(More)
