Abstract:

A new geophysical method was developed to satisfy a need for in-situ density measurements. Various situations, such as a gravity dam wall requires that density measurements should be done without damage to the structure. The sample volume should also not be that large in order to be sensitive enough for variations. This method measures the in-situ density of the weathered layer and other man made structures, using seismic waves in three directions. The seismic waves utilized are P-waves and S-waves. It is however surface waves that are treated like body waves because they do not separate at th

Abstract:

Laser Raman spectroscopy has been widely used for corrosion studies but it appeared that, in most of the cases, the sample under investigation was removed from the media in which it has been corroded prior the Raman investigation. The necessity of running 'ex situ' analysis was often due to the poor Raman response due to the absorption of the scattered light by the solution. A large number of studies have previously been conducted after increasing the amount of scattered light by using surface enhanced Raman spectroscopy. Unfortunately, removing the sample from the media in which it has been c

Abstract:

Environmentally-assisted cracking (EAC) phenomena affect the in-service behaviour of austenitic stainless steels in nuclear power plants. EAC includes such degradation phenomena as Stress Corrosion Cracking (SCC) and Corrosion Fatigue (CF). Factors affecting EAC include the material type, microstructure, environment, and stress. This is an important degradation issue for both current and Gen III+ light water reactors, particularly as nuclear power plant lifetimes are extended ( > 60 years). Thus, it is important to understand the behaviour of the alloys used in light water reactors, and phenom

Abstract:

In-situ 3-D shape measurements with submicron shape uncertainty of fast rotating objects in a cutting lathe are expected, which can be achieved by simultaneous distance and velocity measurements. Conventional tactile methods, coordinate measurement machines, only support ex-situ measurements. Optical measurement techniques such as triangulation and conoscopic holography offer only the distance, so that the absolute diameter cannot be retrieved directly. In comparison, laser Doppler distance sensors (P-LDD sensor) enable simultaneous and in-situ distance and velocity measurements for monitoring

Ce phénomène dit de liquéfaction ou perte de la résistance des sols, résulte de la montée de la pression interstitielle de l'eau lorsque les vibrations sismiques tendent à tasser les grains les uns contre les autres.

Abstract:

The majority of rolling bearings are made from steel due to its suitable mechanical properties. It has been demonstrated that hydrogen evolution from lubricated contacts significantly shortens the steel fatigue life. Significant efforts have been made so far to understand the mechanism of hydrogen-induced failure. However, the failure mechanism is complex and a conclusive theory has remained unknown. The main aim of this study is to develop a novel method, based on the modified Devanathan-Stachurski technique, to experimentally assess hydrogen intrusion into the steel. This new technique enabl

Previous research showed streambank kd and Ï c can vary by up to four orders of magnitude at a single site; therefore, it is essential to determine if the large range is due to natural variability in soil properties or errors due to the test method. The study objectives were to evaluate the repeatability of the JTD and determine how it compares to traditional flume studies. <p> To evaluate the repeatability, a total of 21 jet tests we

There has been increasing concern about the widespread occurrence and persistence of pesticides in the environment. Pesticides can transport among and between environmental compartments, causing pollution in water, soil and air, and posing potential risks to humans and the ecosystem. There is a need to study the fate and behaviour of pesticides in the environment. Over the last few decades passive sampling approaches have aroused attention in detecting pesticides, but they are still under development.

This work presents a novel technique to measure viscosity in-situ and in real time in engine component interfaces by means of an ultrasonic technique. Viscosity is a key parameter in the characterization of lubrication regime in engine parts because it can be related to friction in the contact, and to the lubricant film thickness. Ultrasound is a non-destructive and non-invasive technique that is based on the reflection of sound from interfaces. The reflection from a solid-air boundary can identify, for instance, the presence of a crack in a material, while reflection from a solid-liquid inter

The new technique involves resistance heating of samples, and collection of all evolved carbon as CO₂ between 500°C and 1500°C.

Thesis (Ph. D.)--Joint Program in Oceanography/Applied Ocean Science and Engineering (Massachusetts Institute of Technology, Dept. of Mechanical Engineering; and the Woods Hole Oceanographic Institution), 2007.<br>Includes bibliographical references.<br>Present-day expeditionary oceanography is beginning to shift from a focus on short-term ship and submersible deployments to an ocean observatory mode where long-term temporally-focused studies are feasible. As a result, a critical need for in situ chemical sensors is evolving. New sensors take a significant amount of time to develop; thus, the

Abstract:

Une instrumentation optique entièrement statique permettant le suivi in situ de la croissance d'oxydes fonctionnels par ablation laser pulsé, est présenté. Au travers de l'étude de deux système modèles, que sont la croissance de films minces de La₀. ₆₇Sr₀. ₃₃LMnO₃ sur des pseudo-substrats de SrTiO₃/Si et de couches minces de SrRuO₃ déposées sur des substrats de SrTiO₃ vicinaux, le dispositif proposé permet d'obtenir une précision de mesure sur les épaisseurs de l'ordre de la maille atomique (4Å), d'extraire les paramètres physiques de diffusion des espèces en surface (énergie d'activation de d

Abstract:

This work concerned the design and development of a miniature double torsion (DT) testing rig, for use inside the chamber of a scanning electron microscope, to perform in situ loading studies of brittle materials using the DT fracture mechanics specimen. The in situ performance of the system inside the SEM was highly satisfactory, while still providing free rotation of the attached stepper motor. Crack growth rates of down to 19nm/s were directly observed in PMMA specimens. It was concluded that the technique displayed merit in its ability to contribute to the knowledge base of slow cracking a
