In this paper, a preliminary implementation of a system monitoring the fetus’s heart rate (FHR) has been designed and implemented as a mobile wearable measuring system with remote sensing specifically developed on Node MCU ESP8266 (ESP). In particular, the proposed system uses sensors for heart rate, humidity, temperature, and a transceiver module....

Background: Currently, there is a vast number of electronic and mobile devices which serve for self-evaluation purposes. Specifically, wearable technology has been vastly developed in the last years in conjunction with the usage of mobile phones’ applications for the convenience of their users. In the context of the aforementioned, a proper segment...

Currently, hospitals and health care sectors employ low-cost Internet of Things based remote health monitoring systems and labs in order to collect a subject's or patients’ real-time data. Such a process can be helpful for the early detection of a healthy newborn life and of critical importance for the survival of these lives. In this article, a pr...

Many works have been conducted relevant to rainfall measurements, while the first relevant ones were based on the power loss estimation function from wireless links located back to the early 1940s. It is notable, though, that this innovative idea conduced to many theoretical models correlating the signal attenuation to the rainfall intensity. This...

Green residences are known for their innovative character towards living conditions and low energy emissions. Their reduced ecological footprints design is not only limited to aforementioned but also include the construction of better environmental spaces and conditions even through transforming conventional buildings. Moreover, the psychological f...

Throughout the history of e-learning, the people with disabilities had to face a lot of omissions relevant to every aspect of their learning procedure [1]. These problems ranged from improper web designed pages to the improper way of confronting these types of our fellow citizens. This research takes into consideration the need for radical changes...

In the modern era of vast communication and information dissemination the need for radical security measures must be addressed. Specifically, as the Internet has a tremendous influence on people and especially on younger ones, new threats are added to existing ones such as the Blue Whale phenomenon [1]. The latter is continuously growing with the c...

Robots as well-known are complex machines constituted of artificial parts and digital logic structures. Two key points need special attention in order an artificial humanoid to be finely developed. Firstly, the artificial structure must resemble to a human not only in the figure but moreover in expressed movements accomplishing a body language very...

- Real-time emerging applications are largely delay-sensitive - In this context, Shannon's ergodic capacity cannot account for the transmission delay of the system. - The effective capacity (EC) is an alternative metric that quantifies the system performance under QoS limitation. - EC can be interpreted as the maximum constant arrival rate that a w...

The effective capacity (EC) has been recently proposed as an alternative performance metric to the conventional Shannon’s ergodic capacity. This important metric takes into account the delay constraints imposed by a specific application and their impact on system performance. In this paper, we present novel analytical results on the effective capac...
