1. INTRODUCTION
The geotechnical engineers design foundations and other structures on the soil after investigation of the type of soil, its characteristics and its extent. If the soil is good at shallow depth below the ground surface, shallow foundation such as footings and rafts, are generally most economical. However if the soil just below the ground surface is not good but a strong stratum exist at a great depth, deep foundations, such as piles, wells and caissons are required. Deep foundations are quite expensive and a ....etc

Vibration Transmission from Road Surface Features Vehicle Measurement and Detection

by
Timothy J. Gordon
Zevi Bareket


1. Introduction
The purpose of the project was to investigate which sensor outputs strongly correlate with road surface features, for the purpose of reliable discrimination between different types of road feature. The intention was to reliably identify the vibration characteristics associated with rumble strips at the road edge, and discriminate these special features from other roa ....etc

Laser Micro-Patterning by Means of Optical Fibers with Micro-grinded Lens End Faces



Introduction

Nano-patterning of polymer surface has found a wide range of applications including biotechnology, where holes in the size of hundreds nm can influence the growth and differentiation of relatively large living cells . Instead of the e-beam patterning technique used in the Ref. 1, we ap-plied direct writing by laser-light. In our previous papers , we have demonstrated that th ....etc

ppt on natural fibers in concrete

Concrete is the most widely used construction material in the world and steel reinforcement is always required to meet tensile strength and ductility demands of concrete structures. The production of concrete and reinforced concrete structures creates lots of environmental issues associated with the significant release of CO2 and other greenhouse gases. In addition, the corrosion of steel reinforcement is one of the major challenges that current civil engineers are facing. In the United States, the upgrading o ....etc

xperimental results on ?ber micro-buckling of continuous glass-?ber reinforced hollow-cored recycled plastic extrusions under creep tests are introduced. The full size specimens with dimensions in 2:5 3:5 42 in:3 were submerged in warm water at a temperature of 125 F when they were under a four-point bending creep test. The results show that the micro-buckling of the embedded glass-?ber roving occurs along 90% the length of the specimen on the upper inner surface (compressive side) and mainly during the time between 5 and 100 h from the init ....etc

Chapter 1
INTRODUCTION
Twelve to fifteen percentages of transformer failures are caused by winding deformations provoked by the high electrodynamics forces appearing during short circuits. These geometric vibrations lead to an increase of the winding vibration and, consequently, to an increase of the solid insulation mechanical fatigue. In this way, the isolation can be degraded and short circuit between turns will appear. On the other hand the change in the distance among the conductor implies a change in the serie ....etc
