Device to device(D2D) communication exploits the proximity between mobile devices to allow direct communication. Doing so offers advantages which include less energy consumption, hop gain, reduced load on the base station among others. For instances where the channel between the D2D devices does not allow for efficient direct communication, a suitably selected idle mobile device can act as a relay...
Today many users with their smart mobile devices enjoy the benefits of broadband Internet services. This is primarily enabled by pushing computing, control, data storage and processing into the cloud. However, the cloud encounters growing limitations, such as reduced latency, high mobility, high scalability and real-time execution in order to meet the computing and intelligent networking demands for...
This paper presents an idea of using an Electronically Steerable Parasitic Antenna Radiator (ESPAR) for jamming suppression in IEEE 802.11b networks. Jamming (intentional interference) attacks are known to be effective and easy to perform, which may impose connectivity problems in applications concerning Internet of Things (IoT). In our paper, theoretical considerations are presented and the results...
In this paper, we overview current products available on the market, patents, and state-of-the-art of research for cloud solutions based on wearable ECG biosensors. Building a medical cloud that uses such sensors motivates us for a 24h healthcare monitoring service. Furthermore, we identify several challenges, which have to be solved to enable a complete solution for a generic medical cloud capable...
Today there exist many different types of smart assistants and devices, such as virtual assistants, smartphones and wearables, which have a purpose to coordinate and optimize the daily activities of the people worldwide. The smart assistants' focus is mainly on basic human needs, e.g. browsing, scheduling, navigating and other similar activities. However, not many smart assistants are concerned with...
The exam statistics are crucial for instructors to better assess the exam metrics, e.g., exam duration. However, one statistic, time spent on each question by each student, is not available or difficult to obtain by human observation. In this work, we propose a smart exam system that obtains such statistics and sends data to a web application for further processing by using an internet-of-things based...
In this paper, we present a new loT-based health monitoring approach in which collected medical sensor data is sent to an analysis module via low-cost, low-power and secure communication links provided by a LoRaWAN network infrastructure. We mainly focus on monitoring blood pressure, glucose and temperature in rural areas where cellular network coverage is either absent or does not allow data transmission...
eHealth technology can bring a variety of benefits to patients, caregivers, and health institutions, by facilitating improved healthcare services through the utilization of Information and Communication Technologies (ICTs). The forthcoming generation of healthcare services will require advances in computing and Wireless Sensor Networks (WSNs) in order to leverage truly intelligent and adaptive features...
This paper presents a high resolution method for analyzing of electrophysiological activities using Matrix Pencil Method (MPM). This approach identifies measured signal from nerves to better understanding the functional organization of neuronal ensembles that form the peripheral nerves or the cerebral cortex. Matrix Pencil Method which is used to extract original signals and benefits from minimum...
The paper shows the results of experiments performed at cultures of the anterior pituitary gland cells of domestic pig (Sus scrofa domestica) in vitro. The cells were subjected to the influence of electromagnetic field of extremely low frequencies (60 and 120 Hz) by two hours. We analyzed the cell cycle progression and the metabolic activity. The analysis of the viability and the cell cycle was performed...
In clinical applications, peripheral nerve stimulation is usually delivered by means of commercial devices. The main use of these devices is Transcranial Magnetic Stimulation, in fact the coils are designed for a good stimulation of brain. The purpose of this paper is to design a new coil for magnetic stimulation of nerves, which allows a deep stimulation but, at the same time, characterized by high...
Through the lifetime, a person might stumble upon diseases many of which may be deadly. In order to save the person's life, doctors will prescribe many medicines that may help cure the person. To make stuff easier technology has introduced many new ways to facilitate the struggle that the person may undergo. One of the new ways introduced is an application that makes it easier for cancer and heart...
In this paper we present a review of gait analysis methods used for medical applications. First of all, we introduce a system of real-time gait acquisition. Next, three ways of gait data representation: trajectories, Euler angles and medical angles are described along with the most promising methods of gait analysis based on those representations like gait indices, Dynamic Time Warping, manifold methods...
Minimizing the level of harmful factors in the workplace is one of the basic tasks in maintaining industrial safety, including health care and work comfort. In this view systematic monitoring of harmful factors level by performing reliable measurements in the workplace is crucial. The method of measuring electromagnetic field (PEM) levels in the workplace of particular machines and devices is standardized...
This article describes functionalities and specific features of the “DICOM Network” informational system that provides possibility to collect, process, archive, distribute and visualize data in DICOM format. Presented technical and architecture details and proved the benefits for end users to use the system for secure access to DICOM investigations. DICOM format and protocols described in the article...
Deep learning has become the state-of-the-art in the area of biomedical imaging, leading to a large boost in performance that approaches human levels. Medical microwave imaging is an emerging technology that has great potential especially in the area of breast cancer diagnosis. Moreover, the obtained backscatter signals have also been shown to be a good basis for differentiating malignant and benign...
Cyber-physical system studies request revolutionary methods to identify the vulnerability of the system in order to develop risk assessment and countermeasures and consequently reduce the vulnerabilities. One possible approach to analyze cyber-physical system vulnerability is to study their topology and therefore to quantify the interdependencies on the physical side and on the cyber side. This paper...
