Autism Spectrum Disorder is a multi-parametric disorder affecting people and specially children. It is important to detect autistic children as soon as possible to conduct adequate treatment. In this paper we develop a skin conductance device capable of measuring the galvanic skin conductance and help diagnosing autistic children from the first weeks after their born. As skin conductance is directly...
Melanoma is one type of skin cancer that usually develops from prolonged exposure to UV light. The latter triggers mutations that lead skin cells to multiply rapidly and form malignant tumors. If not cured, Melanoma can result in one's death. Hence, an early detection of this deadly cancer is important to prevent it. Certain lesion characteristics such as Asymmetry, Border, Color and Diameter segmentation...
the noisy and complex nature of many biological signals such as the electroencephalogram (EEG) has long constituted a major challenge in terms of analysis and prediction for single and multivariate problems. Nonlinear signal modeling, despite its widespread applicability, often shows limited success whenever the signal is contaminated with noise or is time varying in nature. We herein introduce a...
Falling is a serious issue among old aged population; it leads to severe injuries and consequences. Inability to move after a fall means that the subject cannot ask for help by himself, which increases the percentage of fall-induced injuries significantly. The objective of this paper is to design and to implement a fall detection and alert system for the elderly persons. It aims to facilitate the...
Low capacity, bulky size and wiring limitations of the conventional wireless multi-channel electroencephalography (EEG) system restrict its use as brain neuromonitoring system. To reduce such restriction, this paper proposes an EEG system based on multi-input multi-output (MIMO) technique and polar coded data. In the proposed system, all the channels are sent and received simultaneously, while the...
Pattern recognition control applied on surface electromyography (EMG) from the extrinsic hand muscles has shown great promise for the control of powered prosthetics for transradial amputees. The use of limb prostheses is essential for maintaining personal independence and a more effective inclusion in society. However, due to their poor control, imposed by the reduced accuracy of hand movement classification,...
Sleep Apnea is a potentially serious sleep disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. It is classified into 3 main types: Obstructive sleep apnea, Central sleep apnea, and Complex sleep apnea syndrome. Obstructive sleep apnea (OSA) represents 80% of the apnea cases which makes it the most common type. Polysomnography is the current traditional method...
Determination of seizure origin is often challenging due to the rapid speed at which electrical activity propagates throughout the brain. The Directed Transfer Function (DTF) has been proposed and validated as a quantitative approach to determine the flow of seizure activity. In this work, outflow and inflow features are extracted from the DTF matrix and used as inputs to a Kmeans unsupervised clustering...
The human activity recognition is widely used for human behavior prediction especially for dependent people. This is achieved to provide safety, health monitoring, and well being of this population at home. In this paper, the problem of human activity recognition is reformulated as joint segmentation of multidimensional time series. The hidden Markov model regression (HMMR) is used to perform unsupervised...
The SSDL (Secondary Standard Dosimetry Laboratory) at the LAEC (Lebanese Atomic Energy Commission) has different calibration methods for various types of dosimeters used in industrial, military and medical fields. The calibration is performed using different beams of X- rays (low and medium energy) and Gamma radiation delivered by a Cesium 137 source. The SSDL laboratory in charge of calibration services...
the use of packaging material in biomedical sensors is a required criterion to achieve certain properties; the most important one is biocompatibility. Response time of biomedical sensors is highly dependent on the sensor's specifications in addition to the type of packaging materials. Compensation of the time delay in the sensor's response due to the packaging material requires detailed mathematical...
The EHG signals are recorded using a multichannel system positioned on the woman's abdomen for the simultaneous recording of 16 channels of EHG. Several studies calculated the features related to EHG propagation by studying the coupling between all possible channels (bivariate analysis). Using all the possible features extracted to characterize propagation, from all possible combinations of channels,...
Locked-in syndrome is known to be a condition in which a patient loses the ability to control nearly all voluntary muscles in the body except for the eye. In today's world, healthcare facilities have the means and equipment necessary to help such patients and take care of their needs, which includes medical care and patient comfort. However, such dedicated professional services are not commonly provided...
Human activity can serve as an identifier of subject health, behavioral patterns, and personal preferences. With the sudden splurge in mobile and wearable devices, activity data has become more readily available to design useful applications that enhance the users' everyday lives without any obtrusive intervention. This paper focuses on the use of a system identification approach to characterize human...
Articular cartilage is a stratified tissue with distinct layers expressing different protein types/amounts and having different cell morphologies. Research on articular cartilage has shown that compression, hydrostatic pressure, and hypoxic conditions tend to give the articular cartilage the properties of the middle and bottom layers of the natural tissue, while surface motion and normoxic conditions...
With the tremendous Internet proliferation, people started to utilize it in their daily life activities. Electronic health (eHealth) is a promising strategy for delivering health care services over the Internet where patients can interact with their health professionals through videoconference sessions to obtain health advices and follow-up information on their health conditions, and exchange views...
Before few decades disabled persons were not able to perform daily tasks such as turning the light on, making a phone call, and even controlling the TV. Disability was an obstacle therefore disabled individuals needed daily monitoring and service. With the evolution of computation power and the progress in neuronal studies, modern technology and science managed to overcome the human disability for...
This paper aims to present a universal mask that enables all adult patients to use it. This mask has a universal size and head gear. It has many options; from among we list the embedded SpO2 and EEG electrode connections. This mask enables also the input of oxygen, nebulizer, air CPAP and medication. A mechanical switch is used to select between air CPAP and nebulizer.
We describe an experimental and educational tool based on the design and development of a robotic arm controlled by EMG surface signals, captured at the biceps brachii muscle and digitally processed. We present the hardware design for the biosignal pre-processing and describe the post-processing and the microcontroller for three servomotors. The design has been used in classroom to promote and integrate...
