Wireless Sensor Network (WSN) is an attractive choice for a variety of applications as no wired infrastructure is needed. Other wireless networks are not as energy constrained as WSNs, because they may be plugged into the mains supply or equipped with batteries that are rechargeable and replaceable. Among others, one of the main sources of energy depletion in WSN is communications controlled by...

measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in irrigation and drainage project schemes. sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...

at present, the solutions to prevent bedsore include using various techniques for movement and displacement of patients, which is not  possible for some patients or dangerous for some of them while it also poses problems for health care providers. on the other hand, development of information technology in the health care system including application of wireless sensor networks (wsns) has led t...

In wireless sensor network (WSN) the use of mobile sink has been attracting more attention in recent times. Mobile sinks are more effective means of balancing load, reducing hotspot problem and elongating network lifetime. The sensor nodes in WSN have limited power supply, computational capability and storage and therefore for continuous data delivery reliability becomes high priority in these ...

Economic valuation of water is useful in the administration and management of water. Population growth and urbanization caused municipal water demand increase in Iran. Limited water resource supply and urban water network capacity raised complexity in water resources management. Present condition suggests using economic value of water as a criterion for allocating policies and feasibility study...

Pre and post-processing are crucial tasks in Knowledge Discovery in Databases (KDD). In this contribution we present an application to a data set from a real water supply network (WSN) in the town of Calarcá (Colombia), located in the so-called "Eje Cafetero" coffee region. We use traditional and well-known techniques of pre and post-processing with the aim of showing its importance in Data Min...

Abstract The aim of the present study was to evaluate presence microplastics in drinking water along a large distribution supply network. Tap collected situ at sampling cabinets using an in‐line procedure that provided representative sample with minimal risk external contamination and avoided transportation volumes laboratory. Microplastics > 50 μm were analysed via Fourier transform infrare...

This paper presents a design of 2.4 GHz low noise amplifier (LNA) for wireless sensor network (WSN) applications using CMOS 0.13 μm Silterra process. The proposed LNA employs a self-biased inverter to obtain high gain and able to operate at low supply voltage. The simulation results indicated that the proposed LNA achieves an input return loss (S11) of -37.7 dB, output return loss (S22) of -28....
