The paper presents the e-learning project and the work until now developed for extending the features of the Italian remote laboratory "G. Savastano" to the academic circles of East Europe, Western Balkan and Mediterranean area. In particular, in the framework of the project "Italian-Croatian remote laboratory distributed on geographic network", the Italian-Croatian collaboration is highlighted. The proposed approach follows EU efforts to implement internal lifelong learning program and influence educational systems of EU partners and neighbor Countries while helping them to overcome problems with their own educational systems and lack of resources. Developed experiments, included in the remote laboratory, give the possibility of achieving practical experience on several fields, while multilingual approach gives the access to such facility to the students coming from different countries. Moreover, the idea of interactively controlled transfer of knowledge and experience offers new opportunities to the remote experiments enabling them to be executed without supervising necessity

A vibration-type ultrasonic vibrator works as an ultrasonic motor when it is pressed slantwise against the surface of an object. In our previous paper we made a trail robot hand with three fingers that each works as an ultrasonic motor. This robot hand can simultaneously grasp a cylindrical body and rotate it about its axis. High torque is obtained when an optimum contact force is used for the ultrasonic motor. We propose a detection method to measure the grasping force of the robot hand by the change in the amplitude of vibration. It was confirmed that the vibration amplitude detected by a piezo-element on the vibrator was decreased almost linearly with increase in the grasping force of robot hand. The grasping force affects very little change in the resonance frequency of the vibrator in comparison with the temperature by its self-vibration.

A safe road-crossing system is very important to improve the mobility of blind people. In this paper, an image-based real-time novel approach is proposed for detecting a zebra crossing and also measuring its length. Detection is achieved through bipolarity-based segmentation along with projective invariant-based recognition and then measurement of length is performed from the number of stripes in the segmented area. Experimental results demonstrate the effectiveness of the proposed technique. © 2005 SICE.

Ship hull form module is the main module in ship design. The problem of creating fair ship hull surface is of major importance in computer Aided Ship Design environment. The fairness of these surfaces is generally considered a subjective notion depending on the judgment of the designers (e.g. visually pleasing, devoid of unnecessary bumps or wiggles, satisfying certain continuity requirements). One of the restriction in ship hull design is that the existing details of a ship design on paper or a ship that already been constructed physically couldn't be reconstructed accurately and concisely in a ship hull design software. This problem can take on many different characteristics, depending on the goal of the reconstruction, the origin of the offset, and tools or methods available to tackle the job. All of these must be taken into account in developing the best approach to solving the problem in the most efficient manner. In this research, the implementation of NURBS method is used because it brings the most convincing results. © 2005 IEEE.

Pedestrian crossings are oangerous places for a visually impaired person to cross safely. This paper describes a simple method for the detection of the location of a pedestrian crossing as well as measurement of its length to enhance the safety and mobility of blind people while crossing a road. A crossing is characterized by zebra pattern i.e. by evenly spaced white stripes on a usual black road surface. Detection of the crossing location as well as measurement of its length is done using this criterion from the image captured by a single camera. The method at first checks for the existence of a crossing;if there exists a crossing then it goes to measure the crossing length. Experimental results on a large number of street scenes with and without crossings demonstrate the effectiveness of the proposed technique. © 2005 IEEE.

This paper presents an improved nonlinear dynamic modeling and control of a proton exchange membrane (PEM) fuel cell stack power system for vehicle applications. The PEM fuel cell system considered includes a fuel tank, supply manifold, cooler and humidifier, fuel cell stack, as well as return manifold. The hydrogen and oxygen have been considered as fuels. The dynamic behavior of the flow path and stack is mainly described with three fundamental equations of mass conservation, nozzle flow, and continuity of isentropic flow. An improved empirical model is employed for the fuel cell system and have been simulated using MATLAB/Simulink. Simulation result shows that the stack pressure and flow rate affects the stack performance in terms of output voltage and currents. Thus, it is crucial to find an optimal control strategy for the pressure that facilitates a control of the output power according to power demand of a load. A new control strategy has been proposed and simulated in conjunction with the fuel cell stack and system models for vehicle applications

This paper describes the effects of specimen size and temperature on viscoelastic properties of microscale SU-8 polymers at intermediate temperatures. Two different types of uniaxial tensile testers examine glassy/rubbery moduli, fracture strain and relaxation modulus of SU-8 polymer specimens. The average glassy modulus at R.T. is 3.5 GPa, which decreases with temperature elevations up to 573 K irrespective of specimen size. Yield stress and fracture strain, however, exhibit the size and temperature dependencies. Besides, we have constructed the master curves of relaxation modulus for micro/milliscale SU-8 polymer specimens. The master curve of microscale SU-8 polymers is in good agreement with that of milliscale polymers, which indicates that the apparent activation energy is independent of the size. The master curves approximated using a Prony series would be widely used to conduct viscoelastic finite element analysis, leading to reliable design of SU-8 micro-components.
