Abstract

In foam extrusion, material density is the most significant factor affecting the product cost and therefore the profitability of the manufacturing process. A reduction in the density of extruded parts reduces the raw material cost and therefore increases its profitability. On the other hand, a reduction in foam density degrades the mechanical properties and geometrical accuracy of extruded parts. Therefore, a critical balance has always to be achieved in order to minimize the material cost while maintaining adequate strength and acc ....etc

Abstract:
Ultrasound Identification is a Real Time Locating System (RTLS) is used to automatically track and identify the location of objects using simple inexpensive nodes (badges/tags) attached to or embedded in objects and devices which then transmit an ultrasound signal to communicate their location to microphone sensors.Ultrasound-based IPS is considered a better alternative to passive Radio-frequency identification (pRFID) in complex indoor environments (such as hospitals), where radio waves may reflect off of metallic or ceramic object ....etc

OBJECTIVE:
In order to prevent thrombogenesis in the artifical heart, a prototype ultrasound thrombolysis system is developed.
Thrombus formation in artificial hearts remains a key risk factor in the death of patients. So, the system is assumed to work continously, dissolving micro thrombi before they can grow.
The purpose of this study is to develop the system that can be mounted in the artificial heart.

Introduction:
Patients requi ....etc

ABSTRACT
This paper presents a new measure of heart rate variability (HRV) that can be estimated using Doppler ultrasound techniques and is robust to variations in the angle of incidence of the ultrasound beam and the measurement noise. This measure employs the multiple signal characterization (MUSIC) algorithm which is a high-resolution method for estimating the frequencies of sinusoidal signals embedded in white noise from short-duration measurements. We show that the product of the square root of the estimated signal-to-noise ratio ....etc

POTENTIAL OF PIEZO ELECTRIC ECOFLOOR FOR GENERATION OF ELECTRIC POWER


The need to generate electricity is the demand for today’s life because of the fact that even if the planet doubles the amount of solar and wind power available, there would still be a shortage of clean electricity. Comparison of different forms of commercial power generation by use of the fuel cycle methods developed in European studies shows that the health burdens are extreme in areas where power stations (base ....etc

by using smart sensors (which following pricipal of Piezo electricity) we can make electricity here in this project we will place smart sensors in the high dense roads (such as traffic jam places in some cities) as this sensors convert static energy of vehicles into power and this can be used for lightning the streets and so on.and similarly by using smartsensors we can extend its application for vehicle tracking, navigation and so on.Using the same smart sensors we need to place those by making 8slots in the wheel of goods train (since indianr ....etc
