The objectives of this paper are to design an inexpensive optical sensor and present the technique for measuring total suspended particulates (TSP) concentrations in air samples. The designed sensor was based on the transmitted properties of particles in air samples. It used LED's as sources and a phototransistor as detector. The detected signals were displayed in terms of the output voltage readings...
The contribution of this paper is the development of a nonlinear position controller for a quadrotor VTOL aircraft using feedback linearization with dynamic extension. The developed controller completely decouples and linearizes the nonlinear dynamical model of the aircraft. The use of dynamic extension has resulted into a fourteenth dimensional controller for the the twelve dimensional state system...
A planar reconfigurable microstrip antenna is proposed by using RF MEMS switches. The proposed antenna structure comprises a center patch antenna known as driven patch and two adjacent microstrip patches defined as wing patches. Cantilever MEMS bridges are introduced to provide to operate antenna either 21.73 GHz or 23.6 GHz depending on the position of the MEMS switches. The design is performed by...
Past work on face detection has emphasized the issues of feature extraction and classification, however, less attention has been given on the critical issue of feature selection. We consider the problem of face and non-face classification from frontal facial images using feature selection and neural networks. We argue that feature selection is an important issue in face and non-face classification...
The improvement in the development of lighting system has not considered eye blinking activity as a parameter to activate the system. In addition, the use of eye blink extracted from EEG signal has not been investigated. This study examines a suitable eye activity for activating home lighting system and then detects the occurrence of this activity from EEG signals. Two types of eye activity were analysed;...
In this paper, we introduce an interactive whiteboard system using image processing and computer vision techniques. This system is more portable than other similar interactive systems, because the system only needs a computer, laser pointer and a camera to communicate with the user. Using a standard laser pointer, user can send his/her commands to the whiteboard, and the system tracks the light and...
As a good mechatronics application, robicle(robotic vehicle) is described in this paper. Robicle(robotic vehicle) is a synergetic integration of robotic intelligence and vehicular mobility. As examples of robicle technology, vision based robicle and magnet based robicle are described. Also, the experimental setups of vision based robicle and magnet based robicle are described.

As the number of field devices in manufacturing systems grows and the functions of the system need to be more intelligent, these devices need to exchange the rapidly increasing amount of data among them. Implementing Ethernet even at the lowest level is suitable for a better interface and offer advantages of direct access of information and equipment diagnostic. This paper proposes the integration...
This paper employs a strategy based on hardware-in-the-loop (HIL) concept to control 3-phase induction motor on-line. The strategy in this work is divided into 3 stages: on-line identification, off-line controller design, and on-line control. The scope of this paper is limited to the controller part and therefore addresses the last two stages of the strategy. The implementation of the strategy was...
This paper highlights the development of online signature verification system using support vector machine (SVM) and VBTablet 2.0 to verify the input signature by comparing database. This may take place by signing directly on to a digitizing tablet by using stylus which is connected to the universal serial bus (USB) port of computer. Owing to the fact that each individual has its own way of presenting...
The gain of SVC depends upon the type of reactive power load for optimum performance. As the load and input wind power conditions are variable, the gain setting of SVC needs to be adjusted or tuned. In this paper, an ANN based approach has been used to tune the gain parameters of the SVC controller over a wide range of load characteristics. The multi-layer feed-forward ANN tool with the error back-propagation...
This paper describes the industrial training programs for Mechatronics engineering student at Sultan Qaboos University. It presents the objectives of the national and international training programs and discusses the importance of such programs in the development of students ability to gain the required practical experience to prepare them for the market before their graduation. Surveys were conducted...
This paper presents a fuzzy logic controller tuned by genetic algorithm (GA) for path planning near the optimal time to avoid obstacles in unknown environments. A GA is applied to modify the input and output membership functions of the fuzzy controller. A Matlab application, Kiks II, is used to simulate a Khepera II robot. Also, this approach is implemented by Khepera II robot. It is also shown that...
This paper describes the effect of implementing a learning system based on emotional behaviors on intelligent soccer robots. The physiological structure of the robot designed with emotional method, so that the robot has human kind feelings such as happiness, sadness, anger, fear and etc. The players make strategic decision and act variously according to the game situations like: the game result, time...
IAT has adopted a Career-Technical Education program in direct response to the UAE needs of well-prepared Emirati scientists, engineers, and technicians who can rise to the challenges of the 21st century. The IAT curriculum is designed to maintain a balance between a rigorous core of academic subjects that develop the knowledge and skills necessary for students to transition into postsecondary education,...
In this paper we explain the basics of our work in devising a Deminer robot with image processing feedback line. It is an educational project that can be regarded as a guide for those who are willing to start using image processing in their mobile robot projects.

In this paper, we investigate the problem of designing Hfrinfin filter for a class of linear descriptor systems which can be realized in practice. It is established that the solution to the filtering problem can be cast in the format of linear matrix inequalities (LMIs). An important special cases is provided. A numerical example is worked out to illustrate the theoretical developments.
