Abstract:
Transducers for high-power sonars, an important tool for undersea exploration and monitoring, may be required to work in deep water where pressures are higher than several tens of MPa. In contrast with the piezoelectric devices commonly used as high-power sonars for seabed resource exploration, electroactive polymers offer the benefits of high coupling efficiency, low cost, and the ability to form large area skins or other devices. One question about the use of electroactive polymers for sonar has been their ability to withsta ....etc

The Challenge

-Portland’s Bureau of Water Supply provides water to Burlington, just northwest of the city.
-A few residences in the higher elevations of Burlington have experienced very low water pressures, prompting the Bureau to ask the students to investigate possible solutions.

Problem Definition

•Low water pressures:
–Are an inconvenience
–Violate Oregon State standards
–Are a potential health risk
•Investigate:
–Reasons for low pressures
–Potential Soluti ....etc

Among all the substances in the universe, water holds unique incomparable positions. Much more than being a major source of energy, it is the primary cause of all life on earth. Also non-traditional and industrial applications of water such as hydraulic transportation of coal and minerals in slurry form, dredging, sprinkler irrigation, cooling and refrigeration etc. are gradually increasing. So much so that availability of water plays primary role in location of an industry today over all other considerations.

Electroactive Polymer “Artificial Muscle” Operable in Ultra-High Hydrostatic Pressure Environment
ABSTRACT—
Transducers for high-power sonars, an important tool for undersea exploration and monitoring, may be required to work in deep water where pressures are higher than several tens of MPa.
In contrast with the piezoelectric devices commonly used as highpower sonars for seabed resource exploration, electroactive polymers offer the benefits of high coupling efficiency, low cost, and the ability to form ....etc

Abstract—

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components’ voltage ratings and energy volumes of passive components of the proposed converter are greatly reduce ....etc

INTRODUCTION-CONCRETE
 The word concrete comes from the Latin word concretus (meaning compact or condensed), the past participle of concresco, from com- (together) and cresco (to grow).
 Concrete is a construction material composed of cement ,coarse aggregate , plus a fine aggregate such as sand, water, and chemical admixtures.
ORIGIN OF HPC AND UHPC
 Environmental aspects
 The necessity to decrease the amount of CO2 in atmosphere.
