The present study propose a smart tooled process based on an MDA approach for the design of ubiquitous applications taking into account context information in order to deliver high-added value services. We will present our platform-independent model (PIM) associated with a graphical modeling workshop (editor) which will allow us to instantiate in a graphical way in order to obtain PIM models, which will be transformed into PSM. We illustrate its implementation on a prototype application in a pervasive environment that tracks the movements of persons who have tested positive to anticipate COVID-19 contaminations.

In this paper, we prove that a class of differential system of degree nine is Liouville integrable by transforming it into a Bernoulli differential equation and we determine exactly its first integral. This allows us to show that this class admits an explicit non-algebraic limit cycle enclosing the origin, here a non-elementary singular point. For singularities, at infinity, this class does not possess singular points.

Quadrotors with rotating and extendable arms, are a new type of transformable drones, which are appeared more recently. According to the assigned paths or missions, they can adapt their variable geometries by folding or extending their arms using some mechanical mechanisms. These latter are based on motors and servomotors distributed in different ways on the quadrotor prototype. The goal of this manuscript is to design and apply a control strategy based on Gains Scheduling using a conventional Proportional Integral Derivative (PID) controller, where its variable gains are well determined for each aerial morphology. This strategy takes into account the variable dynamic of the proposed structure and calculates the quadrotor geometric changes.

Spasmodic Dysphonia (SD) is a neurological problem that involves the laryngeal muscles to malfunction. It is characterized by inappropriate contraction of the laryngeal muscles during speech. To distinguish healthy and pathological human voices, we used a variety of machine learning classifiers to conduct a side-by-side comparison for the detection of this vocal problem. Three commonly used classifiers, namely, knearest neighbors (KNN), Support Vector Machine (SVM), and Decision Tree (DT) were used in this study. Our study is based on the Saarbruecken Voice Database (SVD), a freely accessible German database that contains various samples, vowels, and sentences from normal and diseased voices. In this article, we solely used the sustained phonation of the vowel /a/ low pitch, and the DT algorithm yielded better classification accuracy of roughly 86.66 %.

Alzheimer's disease is progressive brain cell damage. This damage can be slowed down if the disease is detected at an early stage. Computer-Aided detection systems bring great help for this problem especially with the development of convolution neural networks. This work proposes an Alzheimer's disease diagnostic approach based on a segmentation technique and convolution neural networks. We segment an MRI brain image by a recursive thresholding process. This segmentation generates a set of output images witch simulate progressive brain degradation. Convolution neural networks capture this degradation and assign a value that indicates Alzheimer's disease stage.

The aim of the presented work is to compute sloshing frequencies. Two immiscible fluids of different densities are considered in a cylindrical tank. A rigid baffle is placed at the free surface of the upper fluid. The mathematical formulation is done by dividing the fluid domain into sub-domains. The mathematical formulation is done for each sub-domain to find the analytical solution in each sub-domain. The linear water wave theory is used to find the velocity potentials in each sub-domain. The effects of the fluid heights on the natural sloshing frequencies are studied. The findings are supported by relevant graphs.

Service discovery approaches, which reduce the cost of discovering services while also providing ease to users, are gaining popularity. Middleware for context-aware service discovery is necessary for more dynamic and useful service discovery. This study presents a new mobile agent-based paradigm for context-aware service discovery. We characterize the concept 'context' in two ways: one from the perspective of service requesters, such as devices, locations, preferences, and activities; and the other from the perspective of Web services, like protocols for service binding, networks, devices and platforms for service execution, and so on.
