An effective structure based image completion framework is provided in this article. The proposed technique uses a nonlinear second order hyperbolic partial differential equation (PDE) - based model that is based on a properly constructed edge-stopping function and an image mask corresponding to the inpainting zone. The hyperbolic model is then discretized using a consistent explicit finite difference-based...

Meal consumption brings to several consequences on the sympathetic and parasympathetic activation of the autonomic nervous system. Furthermore, olfactory sensitivity decreases at satiation with respect to hunger. However, no research was conducted on the effect of odors on the sympathovagal balance before and after meal. Here, 31 healthy volunteers (16 males, age 31.8±6.7 years) were measured Electrocardiographic...

This paper presents simulations of controlled hypothermia for the human head in view of improving the hypothermia process. We study the effect of head parameters, such as thickness of each region of the head (scalp, bone, gray matter, and white matter) heat generation rate, and blood perfusion rate, and the Peltier element cooling temperature on the behavior of the overall head cooling through induced...
chapter
Several situations require the reliability of hand grasp in different relative positions of the shoulder-elbow system, like handling control elements of working equipment, sporting devices for athletes or rehabilitation supports for temporary or permanently lower limbs impaired people. Therefore the paper presents an experimental method of determining the variation of both anatomical and physiological...
chapter
As fingers represent the main executive instrument that assisted human evolution by performing various activities, starting with work and fight for survival, the flawless functioning of their grip and motion capacity should be a major preoccupation for researchers in biomechanics and ergonomics areas. More and more robotics becomes involved in rehabilitation issues requiring accurate information regarding...
chapter
Wearable systems that aim to monitor human posture are becoming more and more popular due to the technology breakthroughs that allow for lighter, easier to use and nonintrusive devices. However, the use of any device can decline over time if it's not comfortable or affects the user, either physically or psychologically. This study shortly presents an equipment for spine posture monitoring that uses...

The work of this paper is done within the context of European Project E! 9770 i-Light, which aims at developing intelligent systems based on smart luminaries for building monitoring. The work presented in this paper extends the work from i-Light project towards a smart guiding system for buildings. The system is based on the use of smart luminaries and drones. One of the main targets of such a system...
chapter
The paper proposes a modern solution to sustain data communication in an e-Health framework and also the design principles for an e-Health Interoperability Platform for Health Information Systems support. Additionally, the paper presents a mediating service mechanism used to map and convert the context-specific data exchanged between the different parties that are communicating and a dedicated interface...
chapter
The paper presents a number of research challenges for medical data storing into Health Information Systems (HIS), such as complex-data modeling features, advanced classification structures, integration of very complex data, and demonstrates how this area may benefit from the functionality offered by data warehousing. In addition it is presented a case study that configures a data warehouse developed...

The effect slot positions and dimensions have on the size of the ablation zone, reflected power and highest temperature reached by microwave antennas in a hepatic tissue phantom is analyzed with COMSOL Multiphysics. Two antenna configurations are analyzed, coaxial double slot and single slot with choke while taking into account antenna heating.

Medical decision-making can be a difficult task even for human experts. They can be helped by some automatic tools that are developed to offer suggestions when a decision has to be made. The system presented here uses artificial neural networks (ANN) in order to make predictions regarding the risk of Cerebrovascular Accident (CVA). The aim of this paper is to show that these intelligent (but artificial)...
chapter
Telemedicine or medical information exchanging from one site to another via electronic communication to improve a patient's health status offers new ways to deliver care, allows a remote diagnostic or a treatment plan. There is an increased trend towards the development of telemedicine because it is widely looked as a resource with the potential to revolutionize access to care. Major areas where telemedicine...

In the context of demographic ageing the Ambient Assisted Living is a priority approach in healthcare for elderly, with health monitoring (HM) as a central activity. The Cloud-IoT architecture integrates cloud computing and Internet of Things technologies to highlight the advantages derived from their complementarities. The sensing service is aimed at improving the sensor data accessibility and usage...
chapter
We describe the results of an experiment for which we used decisional tree analysis to find a relationship between multiple single nucleotide polymorphisms (SNPs) and a scored health outcome based on a given dataset. We used Gini Index and Minimum Description Length (MDL) to optimize the accuracy of predicting the scored health outcome using SNPs as input variables. Decision tree models were generated...

Introduction: Analyzing social media, insights about how products or services are perceived and used by customers can bring useful information. The aim of this study was to develop and validate 4 self-administered questionnaires to be used in the assessment of how consumers, healthcare professionals, medical students and healthcare providers use social media to retrieve health-related information...
