Adaptative vital signs monitoring system based on the early warning score approach in smart hospital context

Imen Ben Ida, Moez Balti, Sondès Chaabane, Abderrazak Jemai

Changes in vital signs are an important indicator of physiological decline and provide opportunities for early recognition and intervention. The collected vital signs data can be evaluated using several approaches such as the Early warning score (EWS) approach to predict the risk level of patients…

Evaluation of risk factors for fall in elderly using Bayesian networks: A case study

Gulshan Sihag, Véronique Delcroix, Emmanuelle Grislin-Le Strugeon, Xavier Siebert, Sylvain Piechowiak, Cédric Gaxatte, François Puisieux

Background: Falls in the elderly are the number one cause of traumatic death in this population. Prevention of falls requires to evaluate which risk factors for fall are present for a person on the basis of available health information. Our objective is to predict the presence or the absence of 12…

Generating new classes of fixed-time stable systems with predefined upper bound for the settling time

Rodrigo Aldana-Lopez, David Gomez-Gutierrez, Esteban Jiménez-Rodríguez, Juan Diego Sanchez-Torres, Michael Defoort

This paper aims to provide a methodology for generating autonomous and non-autonomous systems with a fixed-time stable equilibrium point where an Upper Bound of the Settling Time (UBST) is set a priori as a parameter of the system. Furthermore, some conditions for such an upper bound to be the…

Scheduling trucks and storage operations in a multiple-door cross-docking terminal considering multiple storage zones

Tarik Chargui, Abdelghani Bekrar, Mohamed Reghioui, Damien Trentesaux

Cross-docking is a logistics process in which products are unloaded through receiving docks and then transferred to shipping docks with almost no storage in between. In this paper, a mixed integer linear programming model (MILP) is proposed to optimise the scheduling, storage, assignment and…

CO2 reduction in a common rail direct injection engine using the combined effect of low carbon biofuels, hydrogen and a post combustion carbon capture system

Edwin Geo Varuvel, Shanmugam Thiyagarajan, Ankit Sonthalia, T. Prakash, Sary Awad, Fethi Aloui, Arivalagan Pugazhendhi

The transportation sector is a major emitter of carbon dioxide emissions. It is a known fact that carbon dioxide is the cause of global warming which has resulted in extreme weather conditions as well as climate change. In this study a combination of different methods of expediting the CO2 emission…

Contribution of Achilles tendon mechanical properties to torque steadiness in persons with transfemoral amputation

Anis Toumi, Rowan Smart, Dimitri Elie, Jennifer Bassement, Sebastien Leteneur, Emilie Simoneau-Buessinger, Jennifer Jakobi

Background: How Achilles tendon mechanics and plantar flexion strength and torque steadiness are altered in the intact leg of persons with trauma-related amputation is unknown. Understanding Achilles tendon mechanics following amputation will further inform rehabilitation approaches to enhance…

Approach for CAD model reconstruction basing on 3D points insertion and surface approximation

Aicha Ben Makhlouf, Nessrine Elloumi, Borhen Louhichi, Dominique Deneux

Reverse engineering (RE) consists in the reconstruction of a geometric model of a 3D object from a set of points, a mesh or a 3D triangulation. This model is a combination of geometric primitives (cylinders, planes, spheres, etc.) and complex surfaces (B-Spline, NURBS…) defined by parameters that…

Experimental analysis to reduce CO2 and other emissions of CRDI CI engine using low viscous biofuels

Edwin Geo Varuvel, Guillaume Fol, Fethi Aloui, Shanmugam Thiyagarajan, M. Jerome Stanley, Ankit Sonthalia, Kathirvel Brindhadevi, C. G. Saravanan

It is the need of the hour to quell the enormous demand of fossil fuels by extending the horizon towards Low Viscous Biofuels. An experimental investigation was carried out to study the performance of the diesel engine, its combustion behaviour and emission aspects while operating it with biofuels…

A scalable dynamic parking allocation framework

Marko Mladenovic, Thierry Delot, Gilbert Laporte, Christophe Wilbaut

Cities suffer from high traffic c ongestion of which one of the main causes is the unorganized pursuit for available parking. Apart from traffic congestion, the blind search for a parking slot causes financial and environmental losses. We consider a general parking allocation scenario in which the…
