The aim of the development is a cardiograph unit that will produce daily monitoring of the patient, the processing of the data and their transmission over the wireless channel. The module detects characteristic points using digital filter unit, which can determine the state of the cardiovascular system.
More than forty million people in the world are epilepsy sufferers. Epilepsy is a neurological disease. That is characterized by the presence of seizures in which the patient has convulsions, among other symptoms, that can cause damage, and even lead him to death. For this reason, it is important to develop systems for allowing early detections. Additionally, the cost of this kind of devices is usually...

The color-word Stroop paradigm is a neuropsychological test often employed for the evaluation of the cognitive processing when a conflict between different attributes of the same visual stimulus is present. In clinical environments, the standard practice for the Stroop test administration is still based on paper supports and stopwatches. Thus, the aim of the present pilot study was to investigate...
Emerging environmental related problems have greater impact on technical, scientific, social and economical fields, which is why this issue needs attention. On a global scale this issue are being sort out using satellite based instruments. This paper discusses a monitoring system which gives information about environmental conditions on a more local level, the implementation area are categorize by...
In a WSN, sink-node gathers data from surrounding nodes and sends it to outside world via a gateway. Therefore, its location information is important to both attacker and network operator. The former can launch attacks on a sink-node to steal information or damage it, while the latter must hide its location to ensure data's safety, and physical protection. Providing sink-node location information...
Effective and efficient management of water resources is becoming unprecedentedly more important nowadays due to the increasing demand from a growing population, increasing standards of living and changing supply due to climate change. Water monitoring technology has directly contributed to the effectiveness of water resource management. Traditional water measurement method, mostly done in laboratory,...
Gas leakage accident occurs frequently due to the aging of pipeline and the third-party interference. To ensure safety during the gas pipeline emergency-repair, it's necessary to detect the gas concentration in the working place. In this paper, a WSN-based monitoring system for gas emergency repairing is proposed. The monitoring system is composed of the wireless nodes and the terminal software. The...
