On recent years, the educational paradigm of electrical and computer engineering has undergone a significant transformation with the advent and the exploitation of computer and communication technologies. Such transformation was necessitated in order to harmonize the learning process with the needs of the daily life. As a result, E-learning has been adopted and has added two major aspects to the learning process: 1) Interactivity;owing to the integration of simulation and multimedia technologies. 2) Ubiquity;owing to the integration of synchronous and asynchronous communication tools, and remote laboratories. Thereby, thanks to E-learning students incentives toward learning have increased. There is no doubt that practical sessions have an intrinsic role in electrical and computer engineering education;they augment the learning outcomes by strengthening the understanding of scientific concepts and theories. However, cost and administration burdens have hindered the adoption of practical sessions in engineering education until the appearance of remote laboratories. Remote laboratories have tackled these concerns by bringing practical sessions online and providing workbenches unconstrained by neither geographical nor time considerations. For these reasons, remote laboratories have proliferated among many universities and institutes around the world to be adopted in most of the disciplines of electrical and computer engineering curricula. A study carried out by the authors deduced that most of the developed remote laboratories around the world are based on common prototypes that are subsets of a common architecture, which is going to be the main topic of this paper. The paper reports on the common prototypes of today's remote laboratories for electrical and computer engineering education and addresses the most outstanding developments for the multidisciplinary applications that are based on such prototypes. These applications encompass embedded systems (e.g. Programmabl

This paper investigates the problem of stability for a class of linear uncertain Markovian jump systems over networks via the delta operator approach. The sensor-to-controller random network-induced delay and arbitrary packet losses are considered for mode-dependent time delays. That is, a Markov process is used to model the time-varying delays which are dependent on the system mode. Based on the Lyapunov-Krasovskii functional in the delta domain, a new sufficient condition for the solvability of the stability problem is presented in terms of linear matrix inequalities. A numerical example is given to illustrate the effectiveness of the techniques developed. © Springer Science+Business Media, LLC 2011.

The rotation matrix estimation problem is a keypoint for mobile robot localization, navigation, and control. Based on the quaternion theory and the epipolar geometry, an extended Kalman filter (EKF) algorithm is proposed to estimate the rotation matrix by using a single-axis gyroscope and the image points correspondence from a monocular camera. The experimental results show that the precision of mobile robot s yaw angle estimated by the proposed EKF algorithm is much better than the results given by the image-only and gyroscope-only method, which demonstrates that our method is a preferable way to estimate the rotation for the autonomous mobile robot applications.

We develop an effective method for improving the segmentation result based on the Multi-Stencils Fast Marching method (MSFM). In MSFM, the gradient information of the image plays a vital role for calculating edges. It is straightforward to obtain the edge of good quality images;however, MSFM may not have robust edge maps available for images with spurious edges. Thus, a special multi-direction circumscribed circle filter is proposed to calculate the image gradient information which is then used in the MSFM. Using the new gradient information, better image contours can be obtained with MSFM. The size of the radius used in our circle filter is constant even the standard deviation of zero-mean Gaussian noise changes while the parameters of mean filter and Canny filter for gradient computation have to be correctly selected according to different noisy images. Our proposed method shows that it is effective through the experiments of image segmentation. © 2012 ACM.

Cloud computing is defined as a pool of virtualized computer resources deployed and scaled-out quickly through the rapid provisioning of virtual or physical machines. Virtual machine services offered by cloud utility providers led to the creation of the ecosystem of cloud services as they enable customers to use computing resources based on the dynamic behaviour of the application and of the computer resource used. As the control system approach is more and more accepted by the computer research communities the perspective of implementing an adaptive resource provisioning and optimization looked attractive enough for investing efforts and human resources to move it from the theory benches to experimental implementations.

The dynamic nature of a system gives rise to dynamical features of epidemic spreading, such as oscillation and bistability. In this paper, by studying the epidemic spreading in growing networks, in which susceptible nodes may adaptively break the connections with infected ones yet avoid being isolated, we reveal a phenomenon, epidemic reemergence, where the number of infected nodes is incubated at a low level for a long time and then erupts for a short time. The process may repeat several times before the infection finally vanishes. Simulation results show that all three factors, namely the network growth, the connection breaking, and the isolation avoidance, are necessary for epidemic reemergence to happen. We present a simple theoretical analysis to explain the process of reemergence in detail. Our study may offer some useful insights, helping explain the phenomenon of repeated epidemic explosions.

Taken it into consideration that human has a great deal of experiences and knowledge of hand postures, if these operating skills of postures are applied to HCI, the simple and convenient human-computer interface can be expected. In fact, tracking, recognition and interaction based on 3D freehand are a part of the cores in our virtual assembly system, but it is a challenging task to track 3D freehand in real-time because of high dimensionality of 3D full hand model. A novel framework for 3D freehand tracking is put forward in this paper. Firstly, we model and investigate this problem under our virtual assembly system (VAS), so as to decrease the arbitrariness and complexity of this issue. Secondly, we put emphasis on building cognitive and behavioral model (CBM) for users in VAS. Thirdly, we research on the way to track 3D freehand based on CBM. The main contributions of this paper are that we propose a new CBM, TPTM model, provide a way to connect users and computer for effective interaction, and present a real-time freehand tracking algorithm. Based on TPTM model, the prediction, the number of particles, the way and scope of sampling, are optimized. TPTM model not only explain behavioral characteristics for users but also can effectively guide the design of freehand tracking algorithm. TPTM model also provides a data structure that can facilitate the implementation of the tracking algorithm. Our experimental results show that the proposed approach raises the quality of each sampled particle or avoid sampling "poor" particles which appear with low probability in each frame, and it tracks 3D freehand in real-time with high accuracy. The number of the drawn particles is reduced up to 5 and the tracking speed increase up to 81 ms per frame. © 2012 Springer-Verlag.

Electromagnetic flow meters based on the principles of Faraday's laws of induction have been used successfully in many industries. In order to achieve velocity profile measurements in single phase and multiphase flows with non-uniform velocity profiles, a novel Imaging Electromagnetic Flow meter (IEF) has been developed which is described in this paper. The novel electromagnetic flow meter uses a microcontroller as the processing core to achieve the function of driving the uniform magnetic field, acquiring voltage signals with electronic system, matrix inversion calculation and result display. The work undertaken in the paper demonstrates that an imaging electromagnetic flow meter for liquid velocity profile measurement is an instrument that is highly suited for control via a microcontroller.

Lesion segmentation plays an important role in medical image processing and analysis. There exist several successful dynamic programming (DP) based segmentation methods for general images. In those methods, the gradient is used as an important factor in the cost function to attract the contours to the boundaries. Since medical images have their characteristics such as low contrast, blurred edges and high noises, the gradient operator cannot work well enough to achieve a satisfactory performance for boundary detection. We define the local intra-class variance and combine it with the dynamic programming method to replace the traditional gradient operation. Experiments on synthetic and X-ray images are carried out and the results are compared with Canny and fast multilevel fuzzy edge detection (FMFED) algorithms. It is demonstrated that the proposed method performs better on medical images with low contrast, blurred edges and high noises. In addition, 483 regions of interest of mammograms randomly extracted from DDSM of the University of South Florida are used to compare our proposed method with the plane-fitting and dynamic programming method (PFDP), and the normalized cut segmentation method (Ncut). The results demonstrate that our method is more accurate and robust than PFDP and Ncut. © 2012 ACM.
