In recent years, the number of devices, applications and services based on a wireless connectivity has grown exponentially resulting in deep changes in our ways of living. New concepts such as the Internet of Things (IoT) associated with the connectivity of sensors and machines will amplify this phenomenon. The term “wireless” refers primarily to radio frequencies (30KHz to 300GHz), the main challenge is the saturation of the spectrum electromagnetic. In this paper, we give a survey of the most significant issues Li-Fi (Light Fidelity) systems that operate at short ranges. We consider the challenging issues facing these systems: link design and system requirements, transmitter and receiver structures, challenges and possible techniques to mitigate the impairments in these systems, applications in medicine and open research issues. In Li-Fi, the data are transmitted in several bit-streams flickering of the LED bulb and decoded on the receiver side. This happens in the form of a binary transmission of data, where ‘0’ is the LED in its ‘off-state’ and ‘1’ is the LED in its ‘on-state’ [1]. We use this concept to transmit data (audio signal) to demonstrate the use-cases and the possible impact it can have in the ever growing field of communication.

In this paper, a new stochastic search strategy inspired by the Grey Wolf optimization theory is proposed for feature subset selection. Grey Wolf optimization algorithm (GWO) is a new metaheuristic optimization technique. Its principle is to reproduce the behavior of grey wolves in nature to hunt in a cooperative way. In this work, we have used the Grey Wolf optimizer and Genetic algorithm to select the most relevant features in a dataset. Then we have proposed a new Genetic Grey Wolf optimization algorithm. In our proposed strategy, feature selection algorithm is formulated as an optimization problem that searches an optimum with less number of features in a feature space and a good accuracy. The goal of our study is to achieve a balance between the classification accuracy and the size of the feature subsets selected. Our proposed approach has been evaluated on 10 standard datasets taken from UCI repository and validated on 02 big datasets used in literature. The experimental results show the superiority of GWO algorithm in classification performance and dimensionality reduction.

Various biomedical great challenges facing our society and the world can be addressed by interfacing biology and medicine with micro and nanoscale technologies. Knowledge and practices in the health field are constantly changing due to new and emerging technologies. These changes improve the quality of diagnosis and care for patients. However, this abundance of innovations is not necessarily easy to follow for all. Thanks to microsystems, medicine knew made remarkable inroads through innovative electronic application to the micrometer scale. This miniaturization has improved diagnosis and treatment of diseases by ultra-miniaturized medical devices. Our work is clearly positioned in this field. Here, we proposed a design suited to trapping of exudate and the release of the active particles for wound healing. The response of our micro-actuator is analyzed quantitatively by implementing a finite element model with the Comsol Multiphysics software, and by modeling the piezoelectric response. This microdevice is composed of two concentric reservoirs combined with piezoelectric micro-actuators. The first reservoir is used for the aspiration of exudate. The second is used for the injection of a drug. On these reservoirs, we superimpose piezoelectric micro actuators for pumping the exudate and the drug injection.

In this talk an introduction to unmanned aerial vehicles will be made, detailing their operation, main uses, and main research challenges. Next, different applications and systems developed in our research group will be discussed, showing how wireless communications can be used to achieve advanced features such as swarm creation and collision avoidance.Regarding collision avoidance, the Mission Based Collision Avoidance Protocol (MBCAP) is presented. MBCAP is a novel UAV collision avoidance protocol applicable to all types of multicopters flying autonomously. It relies on wireless communications in order to detect nearby UAVs, and to negotiate the procedure to avoid any potential collision. Experiments show that MBCAP is very effective at impeding collisions, while introducing a flight time overhead that is typically in the range from 15 to 40 seconds.Concerning swarm creation, the Mission-based UAV Swarm Coordination Protocol (MUSCOP) is presented. It allows multiple UAVs to perfectly coordinate their flight when performing planned missions. Experimental results show that the proposed protocol is able to achieve a high degree of swarm cohesion independently of the swarm formation adopted, being resilient to channel losses, and introducing a low synchronization time overhead.

This paper presents the development of a versatile software framework enabling the multiform and seamless evaluation of distributed systems: from fast and flexible simulation to actual system execution. The OpenStack datacenter resource management infrastructure is considered as the main entry point of the proposed framework. Since the technological bridge between OpenStack and systems in production already exists, we propose a similar bridge to the popular SimGrid distributed system simulator. This way, actual system resources, and abstract SimGrid system models can be managed uniformly from the OpenStack environment. This paves the way to the multiform design exploration of distributed systems.

Smartphones, particularly iPhone, can be relevant instruments for researchers because they are widely used around the world in multiple domains of applications such as animal behavior. iPhone are readily available on the market, contain many sensors and require no hardware development. They are equipped with high performance inertial measurement units (IMU) and absolute positioning systems analyzing user’s movements, but they can easily be diverted to analyze likewise the behaviors of domestic animals such as cattle. Using smartphones to study animal behavior requires the improvement of the autonomy to allow the acquisition of many variables at a high frequency over long periods of time on a large number of individuals for their further processing through various models and decision-making tools. Indeed, storing, treating data at the iPhone level with an optimal consumption of energy to maximize battery life was achieved by using edge computing on the iPhone. This processing reduced the size of the raw data by 42% on average by eliminating redundancies. The decrease in sampling frequency, the selection of the most important variables and postponing calculations to the cloud allowed also an increase in battery life by reducing of amount of data to transmit. In all these use cases, the lambda architectures were used to ingest streaming time series data from the Internet of Things. Cattle, farm animals’ behavior consumes relevant data from Inertial Measurement Unit (IMU) transmitted or locally stored on the device. Data are discharged offline and then ingested by batch processing of the Lambda Architecture.

INTRODUCTION: Systematic errors of up to 20mm and more have been reported in determining the center of pressure (COP) with force plates [1]. Experimentally these errors are determined by applying a point load to the force plate at a defined point and comparing the true coordinates of this point with the coordinates calculated from the signals of the force plate. The correction formulas given in the literature use polynomial approximations based on these measurements [4]. From analytical models it is known that the errors are due to the statically overdetermined configuration [3]. In this paper it will be shown that only with certain restrictions can these correction formulas be applied to distributed loads. The general construction of a force plate consists of a stiff plate resting on four posts (Fig. 1). In each of the four posts (i=1...4) there are tri-axial force transducers measuring compressive and tensile forces Fi z , in the z direction, as well as shearing forces Fi x , and Fi y , in the x and y directions respectively. From these
