Ambient Assistive Living (AAL) applications allow elderly people to maintain a healthy life style and live longer in their homes. In this paper we describe a platform that combine physical exercises, health monitoring with a reminder component implemented as a multimodal interface adapted to elderly needs for maintaining a healthy lifestyle for elderly people.
We are using life-size mannequins within an education subjects, e.g. “Medical devices” for a demonstration of basic principles of modern clinical devices such as mechanical lung ventilator. Limitation of many simulators is uniformity of its outputs for same input parameters. This paper describes variability of the vital signs of the mannequin when the same scenario was used for different base patients...
In order to assess the wearing of polyethylene with high molecular density in knee prosthesis due to friction processes, a mathematical model of the forces at work has been developed.
Transient elastography has been the mostly well established technique to be used for the assessment of hepatic stiffness. So far, it has the strongest body of evidence. It is known as a user-friendly procedure, requiring only a short procedure time, and offering immediate results and high patient acceptance rates. Nevertheless it is characterized by a series of technical and clinical biases. Our study...
Infantile hemangiomas (IH) are a type of benign vascular tumors that appear within the first 5 months of life. The assessment of lesion size and its evolution in time is done manually by the physician, using a ruler, and this measurement is not very accurate. This paper presents a method for automatic measurement of the IH size. The work is divided in two parts: automatic computation of the size of...
A novel similarity metric is proposed here for evaluating the performance of various image denoising and restoration techniques. A testing methodology implying four types of noise contamination on medical images has been used to determine a vital threshold used in the computation of the proposed similarity index. The results are described along with values for known similarity indices. Graphical representations...
Background: Evaluating patients' satisfaction after endoscopic retrograde cholangiopancreatography (ERCP) isn't yet one of the professional state of the art practices. The multimedia informed consent may be a way in which to improve communication with the patient and therefore overall patient satisfaction. The aim of our study was to evaluate patients' satisfaction and to establish a link to patients'...
Touch input requires precise eye-hand coordination skills to be effective and efficient. In this work, we address touch input from the new perspective of understanding human vision and eye-hand coordination mechanisms in the fields of neurobiology and psychology, and we highlight implications of neurobiological and neurocognitive approaches of human vision for touch target acquisition on mobile devices...
The development of dental nanomaterials with antibacterial properties represents a new step against antibacterial resistance, but there are concerns regarding the efficacy of the antibacterial effects of nanoparticles when mixing them with other materials or when using them for surface coating materials. The objective of this review article is to summarize the experimental data regarding the antibacterial...
Congenital Heart Disease (CHD), the most common form of congenital anomaly, affects nearly 1% of newborns and potentially dramatically increases neonatal mortality.
Introduction. The priority directions in pediatric otorhinolaryngology are development of diagnostic criteria in chronic tonsillitis in children and argumentation of complex conservative therapy tactics to preserve palatine tonsils as important organs in local and general immunity.
Biochemistry analyzers are medical equipment which help to diagnose the state of our health very fast and the assays that are run are very accessible. A biochemical profile is a set of assays that evaluates the functions of internal organs, the enzymes that participate in reactions in our body and the level of electrolytes, which adjust the main vital functions. In order to obtain the best evaluation...
This paper deals with some research outcomes in the field of FES&BCI based rehabilitation equipment, specifically, hybrid exoskeleton&FES&BCI systems. The novelty of the proposed FES&exoskeleton systems is the balanced control between FES, voluntary motion induced by the user and the exoskeleton trajectory guidance. The upper limb exoskeleton&FES hybrid EXOSLIM system has been...
This paper presents some theoretical and experimental physio-pathological aspects of certain behaviors on patient bipodal posture. In the first part of paper, aspects of ocular physio-pathology are presented in relation to the level and form of impaired visual function of the patient. Experimental structure and the evaluation are issues presented in the second part of the paper. Experimental structure...
Control and monitoring of asthma progress is highly important for patient's quality of life and healthcare management. Emerging tools for self-management of various chronic diseases have the potential to support personalized patient guidance. This work presents the design aspects of the myAirCoach decision support system, with focus on the assessment of three machine learning approaches as support...
The paper presents a study in vitro concerning the deviation from sphericity of some components of total hip prosthesis (acetabular cups and femoral heads). Prosthesis have been tested on an experimental stand, on which were simulated the loads and movements from coxo-femoral articulation. Deviation from sphericity was determined in accordance with ASTM standards and specifications from the ISO on...
The aim of our study was to evaluate the effectiveness of tympanostomy tube insertion in comparison with other modalities of treatment in children with chronic otitis media with effusion (COME) and recurrent acute otitis media (RAOM). Children with RAOM and COME were assigned to three subgroups with different modalities of treatment and examined during 1 year. Physical and acoustical characteristics...
In this paper we present experiments made on an extension of a well-known simple global color criterion and we present the results obtained in iris recognition on two known iris databases, UBIRIS and UPOL. All tests were done for three different color spaces, RGB, HSV and LAB, and two discriminative classifiers, k-NN (k - Nearest Neighborhood) and SVM (Support Vector Machine) were used in our experiments...
The paper presents the design and construction of an experimental stand for in vitro testing of total hip and knee prosthetics. It is composed of a pneumatic circuit (two pneumatic cylinders, a rack-piston oscillating motor), an electric circuit (an electric motor of 24 V DC, a power source, a command and control circuit), a device for cycles number counting, sensors for acceleration, rotational speed...
