Abstract

An intrusion detection system is a device or software application that monitors network or system activities for malicious activities and produces reports to a management station. Three-tier accelerometer sensors are used to detect intrusion ships. Spatial and temporal correlations of an intrusion are monitored to increase detection reliability. The ocean and ship generated waves are differentiated by signal processing and cooperative signal processing techniques. This is done based on their specific different energy spectrums. Traditional ship detection methods can monitor a large area but cost a more. This method can be cheaper. Moreover, the satellites cannot complete real-time monitoring. The schemes with Wireless Sensor Networks (WSN) are cheaper and can be deployed almost everywhere we want. Power management is a very important factor in wireless sensor networks.
A wireless sensor node is usually battery operated and therefore energy constrained. The sensor node is not activating by any intrusions and the event status is taken as sleep state. At this situation, extra energy can be gained by shut down the sensor node to maximize its lifetime. This process can be done by an Instantaneous Power Saving Method (ISPM). To maximize the battery life, event-driven power consumption is critical. Based on instantaneous processing requirement, we adapt the processor’s operating voltage and frequency dynamically. Due to this, this research performs energy saving in wireless sensor networks.

Abstract

This paper gives an impression of sensor network and its technology and fields of application of sensor networks. It reflects in aspect selected fields of application that have high probability. However studies clearly guess an overall strong positive effect in smart buildings, smart industrial applications as well as precision agriculture and agricultural, consequences for the arena of smart conveyance are diversified due to recoil effects [1]. As significance, demand for transference and thus the consumption of properties both increase which can lead to an overall negative effect.

Abstract

A prospective, controlled trial was conducted to assess the effect of early physical therapy intervention on low birth weight infants during the first six months of life. A cohort of 100 low birth weight (LBW) infants who got admitted in neonatal intensive care unit (NICU) and referral newborn (RNB) of Raja Muthiah Medical College and hospital(RMMC&H) were included prospectively. Infants who received regular early physiotherapy intervention were assigned as interventional group (EI) & infants who were advised but did not turn up for early intervention as comparison group (NEI).The Amiel-Tison neurologic examination and Denver developmental screening test (DDST) were used and results were compared. Results: Better performance of infants was found in EI group in neurological and developmental domains. Conclusion: The data suggest significant benefit of the use of EI program over NEI in LBW infants.
