Retrorectal Schwannomas: Atypical Presentation and Controversial Surgical Management

Wided Trimech, Farouk Ennaceur, Hiba Ben Hassine, Hanen Zneti, Faouzi Noomen, Khadija Zouari, Paola De Nardi
2021 Case Reports in Surgery  
Schwannomas also known as neurilemomas are benign tumors. Retrorectal schwannomas are extremely rare, accounting for 1 to 5% of all schwannomas. They are mostly asymptomatic but may present with symptoms such as pelvic pain, back pain, lower extremities pain, or constipation. Physical examination is often poor. Imaging (CT, MRI) and fine needle biopsy can often help orient the diagnosis. The treatment of choice is monoblock resection of the mass. The prognosis is good. Recurrence has been

We performed a surgical resection and the histological examination was consistent with the diagnosis of benign (ancient) schwannoma.

Lyapunov-Based Dynamic Neural Network for Adaptive Control of Complex Systems

Farouk Zouari, Kamel Ben Saad, Mohamed Benrejeb
2012 Journal of Software Engineering and Applications  
In this paper, an adaptive neuro-control structure for complex dynamic system is proposed. A recurrent Neural Network is trained-off-line to learn the inverse dynamics of the system from the observation of the input-output data. The direct adaptive approach is performed after the training process is achieved. A Lyapunov-Base training algorithm is proposed and used to adjust on-line the network weights so that the neural model output follows the desired one. The simulation results obtained verify the effectiveness of the proposed control method.

Adaptive Internal Model Control of a DC Motor Drive System Using Dynamic Neural Network

Farouk Zouari
2012 Journal of Software Engineering and Applications  
This work concerns the study of problems relating to the adaptive internal model control of DC motor in both cases conventional and neural. The most important aspects of design building blocks of adaptive internal model control are the choice of architectures, learning algorithms, and examples of learning. The choice of parametric adaptation algorithm for updating elements of the conventional adaptive internal model control shows limitations. To overcome these limitations, we chose the

The results of this latest control showed compensation for disturbance, good trajectory tracking performance and system stability. 169 adaptive internal model control systems is developed in Section 5.A comparative study between these two control schemes is illustrated in Section 6 and a conclusion is drawn in Section 7. Description of DC Motor A DC motor can be used in a variety of industrial applications [29] . The type DC motor is characterized by the following equations [30]: The electrical equation: with 0 1   

Robust Adaptive Control for a Class of Nonlinear Systems Using the Backstepping Method

Farouk Zouari, Kamel Ben Saad, Mohamed Benrejeb
2013 International Journal of Advanced Robotic Systems  
This paper develops a robust adaptive control for a class of nonlinear systems using the backstepping method. The proposed robust adaptive control is a recursive method based on the Lyapunov synthesis approach. It ensures that, for any initial conditions, all the signals of the closed-loop system are regularly bounded and the tracking errors converge to zero. The results are illustrated with simulation examples.

Neurofibromatosis Type I and Stromal Tumor with a Multiple Digestive Localization

Amina Chaka, Farouk Ennaceur, Mohamed Amine Tormen, Ibtissem Korbi, Faouzi Noomen, Khadija Zouari, Mario Ganau
2021 Case Reports in Surgery  
Neurofibromatosis type I (NF1) is also known as von Recklinghausen disease. It is a genetic disorder that affects the growth and development of nerve cell tissue, which is characterized by a multisystem disorder and an increased risk for cancer. The incidence of gastroduodenal stromal tumor during Recklinghausen disease can reach 35% in autopsies and 5% in clinical cases. In our case, the diagnosis of neurofibromatosis type I was made in a middle-aged women initially diagnosed with a pancreaticoduodenal tumor.

Output-Feedback Controller Based Projective Lag-Synchronization of Uncertain Chaotic Systems in the Presence of Input Nonlinearities

Abdesselem Boulkroune, Sarah Hamel, Farouk Zouari, Abdelkrim Boukabou, Asier Ibeas
2017 Mathematical Problems in Engineering  
This paper solves the problem of projective lag-synchronization based on output-feedback control for chaotic drive-response systems with input dead-zone and sector nonlinearities. This class of the drive-response systems is assumed in Brunovsky form but with unavailable states and unknown dynamics. To effectively deal with both dead-zone and sector nonlinearities, the proposed controller is designed in a variable-structure framework. To online learn the uncertain dynamics, adaptive fuzzy

To prove the stability of the overall closed-loop system (controller, observer, and drive-response system) and to design the adaptation laws, a Lyapunov theory and strictly positive real (SPR) approach are exploited. Finally, three academic examples are given to show the effectiveness of this proposed lag-synchronization scheme.
