As the technology is moving towards the world of wireless systems, the concept of inductive power transfer between galvanically isolated coils is becoming significant for low power application. The main advantages are its minimum influence of external atmospheric factors, smooth supply of power to moving systems, least maintenance and ruggedness. In general, the system should be designed in such a way that the received power at the load should not be less than the minimum required power up to a certain distance between coils. This paper proposes the implementation of two different power...

A significant amount of research and development work has been initiated by several research groups in the recent years to tackle the issue of water monitoring. Wireless sensor network (WSN) is predominantly used for water monitoring application. Depending on the application constraints and performance required, different implementations are considered for the development of wireless sensor nodes for water monitoring applications. Some are based on microcontroller, digital signal processor (DSP), application-specific integrated circuit (ASIC), field programmable gate array (FPGA),...

The purpose of this work is to study and analyze the data associated with the marine traffic operations and to estimate the resulting noxious substances emissions to find a solution for potential pollution reduction. The obtained results provide useful information to assess the cost-effectiveness of possible strategies (such as shore-site electricity) for bringing pollutants down, in order to reach a wealth based on environmental preservation.

Wireless sensor systems can help to improve or to expand instrumentation for environmental monitoring systems. A mechanical converter solution will be proposed to convert energy using the Kármán vortex street within lotic water. Within the system design process the focus of this contribution will be in the investigation of the mechanical coupling of turbulences and a mechanical energy converter.

In order to improve the routine of water quality monitoring and reduce the risk of accidental or deliberate contaminations, this paper presents, the development of low cost and durable on-line water quality system includes multi-parameter sensors, acquisition card, communication system and another accessories. These sensors can be installed across water distribution networks within an interface to control the continuous flow and pressure of the large volume water samples (rivers, lakes). The flow water is made through a channel which is designed on one side of this interface. In our system,...

The Wireless Sensors Networks (WSN) technology has spread rapidly into different fields and sectors, agriculture is one of them. WSNs for agriculture are used for their cost effectiveness to improve the productivity, profitability and sustainability of the whole farming system. This work focus on the design and implementation of an intelligent, low cost and fully automated irrigation system which will be able to provide full time monitoring. The system is composed of different types of nodes. Each node consists of a TelosB mote and adequate sensors and actuators. In addition, a gateway unit...

Control and measurement of electrical activities of brain, with implantable devices and systems, have been becoming topics of key interest in physiological measurements even in micro and nanotechnology issues. Implantable devices under the scalp and out of the brain are subject to delicate design and construction. This paper presents a thermal analysis of a designed case for recording signals for EEG applications. The paper also illustrates the materials used for this purpose. The thermal analysis has been performed using Comsol Environment.

Brain activity source localization is an important issue related to origins of neurological epilepsy disorders which reveal oneself by specific EEG activity. Epilepto-surgery treatment is based on complete removing or disconnecting of epilepsy bearing which is responsible for seizure. However precise localization of epileptogenic tissue partly depends on an accurate localization sources of seizure activity or/and inter-ictal specific activity. In this work the DOA (Direction of Arrival) estimation method Multiple Signal Classification (MUSIC) is used to locate distinct sources of specific...

Electroencephalography (EEG) is a well established methodology to record the electrical activity of the brain. We can be interested in monitoring the cerebral electrical activity for different purposes: studying the cognitive activity, interfacing the brain with the machine, extracting diagnostic information, etc. Artifacts are unwelcome signals, generated by electromagnetic sources not related to cerebral activity, that may overlap to the EEG signals and affect their processing. Whatever the goal of EEG processing, a preprocessing step consisting in artifact removal is normally required....

In this paper, an assessment tool based on smartphone to evaluate disease severity in patients with Parkinson’s disease is proposed. Parkinson’s disease is a pathology widely spread in middle aged and aged individuals of any sex. It is a debilitating and degenerative disorder affecting the central nervous system. Distinctive symptoms are movement-related such as rigidity, slowness of movement and shaking. Further symptoms could be even cause of behavioural problems such as dementia. Today, the disease severity assessment is performed by means of simple visual examination or by using specific...
