The increasing need for efficient vehicle diagnostics and performance optimization has led to advancements in On-Board Diagnostics (O.B.D) systems, particularly the O.B.D-2 protocol. This study investigates the real-time monitoring capabilities of O.B.D-2 for assessing engine load under various driving conditions. Three different vehicles were exam...

The transportation sector has a significant impact on climate change, as it is responsible for 20% of the global greenhouse gas (GHG) emissions. This paper evaluates the role of electric vehicles (EVs) in achieving Europe's ambitious target of carbon neutrality by 2050. The limitations of internal combustion engines (ICEs) along with the recent adv...

The adoption of electric vehicles (EVs) has emerged as a significant measure to reduce greenhouse gas emissions and promote cleaner transportation towards the goal of decreasing temperature increase over 0.5°C by 2050. The evolution of battery technology allows for massive exploitation of EVs as they require low maintenance and have over 200% highe...

Manual intravenous (IV) monitoring delays, put patients at risk, as the reaction time of nursing staff can be critical to the patient’s health. The widespread use of LoRa networks today is a reality. The deployment of devices and applications based on LoRa networks in healthcare environments, such as hospital facilities, is of great interest and ca...

Water quality is crucial for public health, especially in areas with water scarcity, such as remote islands. Although reliable measuring devices are available, on-site manual testing, such as in water tanks, is still necessary. In order to determine the quality of drinking water, a set of measurements should be carried out automatically, at regular...

Air quality directly affects the health of humans. The health implications of poor air quality are recognized by professionals and the public alike and these concerns have driven both the proliferation of formal sensor networks, but also low-cost sensors which can be used in the home. The advancement of technology in recent years has also led to th...

Air quality is a subject of study, particularly in densely populated areas, as it has been shown to affect human health and the local ecosystem. In recent years, with the rapid development of technology, low-cost sensors have emerged, with many people interested in the quality of the air in their area turning to the procurement of such sensors as t...

Nowadays, the study of air quality has become an increasingly prominent field of research, particularly in large urban centers, given its significant impact on human health. In many countries, government departments and research centers use official high-cost scientific instruments to monitor air quality in their regions. Meanwhile, concerned citiz...

Ιn this work an integrated heart rate and SpO2 monitoring system is presented. A portable device was created with the aim of sending the measurement data, in real time, to a central in...

Air pollution, which is mainly caused by industrialization, intensive transportation, and the heating of buildings, is one of the most important problems in large cities because it seriously harms the health and the quality of life of their citizens. This is why air quality is monitored not only by governmental organizations and official research i...

Lithium-ion batteries are utilized everywhere from electronic equipment, smartphones and laptops to electric vehicles; however, certain disadvantages are inherited including high-cost and low-temperature range, caused by high currents. In this paper, a compact and low-cost battery management system is presented which can measure the voltage and cur...

As the use and development of Internet of Things is very popular nowadays, one of the most widespread ways of exchanging data from such arrangements is the use of the LoRa network. One of the advantages offered by this technology is the ability to provide low power consumption as well as wide wireless coverage in an area. Although in research, ther...

With the exponential development of MEMS (Micro-Electromechanical Systems) in the last decade, emphasis has been placed on the construction of IoT devices in conjunction with an appropriate information system to assist citizens in various fields (transportation, trade, etc.). More specifically, in the health sector,, there are specific IoT devices...

The continuously growing human activity in large and densely populated cities pollutes air and consequently puts public health in danger. This is why air quality monitoring is necessary in all urban environments. However, the creation of dense air monitoring networks is extremely costly because it requires the usage of a great number of air monitor...

Concentration of particulate matter constitutes a major, environmental problem affecting human health especially in urban areas. Although research centers and government agencies have air quality monitoring systems installed, their limited number prevents the spatiotemporal analysis in urban areas. EU funds research projects to engage citizens for...

The air quality, especially in cities, is an important factor that affects life quality and health. Despite the continuously growing trend to monitor the air quality the challenge to collect reliable data is still on the table. Particulate matter, Nitrogen Dioxide and Ozone concentrations constitute some of the most widely measured quantities in or...

Nowadays, air quality is an important factor that affect life quality, especially in big cities. Concern about the air citizens breathe is of increasing interest since it has impact on their health. For this reason, there is a movement of citizens who want to actively participate in air quality measurements. An affordable solution is the use of low...

The risk of theft of goods is certainly an important source of negative influence in human psychology. This article focuses on the development of a scheme that, despite its low cost, acts as a smart antitheft system that achieves small property detection. Specifically, an Internet of Things (IoT)-based participatory platform was developed in order...

The aim of this study is to present the development-and field evaluation-of an IT platform for the monitoring and recording of atmospheric conditions in urban environments, mainly through a wireless network of sensor-based air quality monitoring systems that can supplement existing infrastructures.

Among the various non-destructive geophysical methods applied for detecting subsurface imperfections and for determining the composition of the Earth’s crust, the electromagnetic (utilized via Ground Penetrating Radar - GPR) is, perhaps, the one with the highest potential for tracking structures of limited dimensions [1, 2]. The present study attem...

Pressure Stimulated Currents (PSCs) are emitted while brittle materials of high electrical resistivity are subjected to mechanical loading. The PSCs are related to the generation of cracks and the consequent evolution of cracks’ network in the bulk of the specimen. In the experimental protocol described here cement-mortar beams of rectangular cross...
