Resumen

This dissertation describes the development of atomic force microscope cantilevers as surface stress sensors for monitoring surface processes at the solid-liquid interface. Micromechanical bending-beams are highly sensitive stress sensors; stress changes as small as 10<SUP>-4</SUP>Nm<SUP>-1</SUP> can be detected using this type of bending-beam, whereas typical stress changes associated with monolayer processes are 0.1-1Nm<SUP>-1</SUP>. As well as offering high sensitivity, micromechanical cantilevers have a fast response time (0.5ms in liquids) which means they are ideally suited for fast st

Approved for public release; distribution is unlimited.<br>An instrumented spar buoy, Met-on-a-Stick (MOAS), was designed, deployed, and validated for measuring the air sea interface processes at multiple levels. This system was deployed in June 2010 off the coast of California, and January and February 2011 in Monterey Bay. The system provides mean measurements of wind, temperature, and humidity at multiple levels within 3 m above the sea surface and measurements of sea surface temperature at three levels below ocean surface. It is small enough to be deployed and retrieved by two people.

Resumen

Low-frequency noise has been measured on commercial power MOSFETs. These devices, fabricated with the VDMOS structure, exhibit a 1/f type noise spectrum. The interface state density obtained from noise measurements was compared with that obtained from the subthreshold-slope method. Reasonable agreement was found between the two measurements. The radiation effects on the noise power spectral density were also investigated. The results indicated that the noise can be attributed to the generation of interface traps near the Si-SiO₂ interface. The level of interface traps generated by radiation wa

Resumen

The effects of high field stress on interface trap densities (Dit in MOS transistors are compared using three methods: charge-pumping, subthreshold swing and 1/f noise. The experimental MOS devices subjected to high field stress originated from two wafer lots processed with different concentrations of copper in the buffered oxide etchant. For the charge-pumping and subthreshold methods, no dependency is found on stress current polarity, wafer lot or transistor type (n- or p-channel). These two methods yield similar Dit values.

Resumen

Robot manipulators are considered as the key element in flexible manufacturing systems. Nonetheless, for a successful accomplishment of robot integration, the robots need to be accurate. The leading source of inaccuracy is the mismatch between the prediction made by the robot controller and the actual system. This work presents techniques for identification of actual kinematic parameters and pose accuracy compensation using a laser-based 3-D measurement system. In identification stage, both direct search and gradient methods are utilized. A computer simulation of the identification is performe

Resumen

Droplet Interface Bilayers (DIBs) have a number of attributes that distinguish them from conventional artificial lipid bilayers. In particular, the ability to manipulate bilayers mechanically is explored in this thesis. Directed bilayer area changes are used to make precise measurements of the specific capacitance of DIBs and to control the two dimensional concentration of a membrane protein reconstituted in the bilayer.

Resumen

To improve optical measurements, which are degraded by optical distortions, wavefront correction systems can be used. Generally, these systems evaluate a guide star in transmission. The guide star emits wellknown wavefronts, which sample the distortion by propagating through it. The system is able to directly measure the distortion and correct it. There are setups, where it is not possible to generate a guide star behind the distortion. Here, we consider a liquid jet with a radially open surface.

Conventional ISAM films are fabricated by alternately immersing a substrate into oppositely-charged polyelectrolyte solutions. The polyelectrolytes bind electrostatically to the oppositely-charged substrate, and thus reverse the charge of the substrate. The charge reversal limits the amount of adsorbed material and prim

Resumen

Dans le domaine photovoltaïque, les performances des cellules solaires sont impactées par deux problématiques majeures : les pertes par réflexion et les pertes par recombinaisons. Le premier objectif de ce travail est de diminuer la réflexion de la lumière à la surface du silicium en utilisant une couche antireflet de nitrure de silicium. Cette dernière est réalisée par pulvérisation cathodique magnétron en utilisant des gaz non toxiques (Ar, N2). Le deuxième objectif de cette étude est la passivation des centres de recombinaison au niveau de l'interface couche antireflet/silicium. Pour cela,

Resumen

Air voids are known to be sites for the initiation of corrosion in reinforcing steel bar in concrete structures. The development of suitable non-destructive methods for measuring the void content at the reinforcing steel/concrete interface would therefore provide a predictive measure of the susceptibility of a structure to future reinforcing steel corrosion, and also allow the concrete composition to be adjusted during subsequent pouring. Of particular interest here are air voids from 1 to 10 mm in size. Normal hardened concrete contains from 1 - 2 % air voids by volume. A literature survey of

Resumen

The origin of this project was the problem of foot ulceration in the diabetic patient. Whilst the principal cause of the susceptibility to foot ulceration in patients with this pathology, and others such as leprosy, is abnormal physiology, there is no doubt the mechanical forces that are applied to the foot surface are a major factor. Currently several devices are available to measure the perpendicular forces at the foot-shoe interface (ie. the "pressure" distribution). However the full assessment of tri-axial forces at this interface has largely eluded quantification despite the fact that it

Resumen

Interconnects in power module result in thermal interfaces. The thermal interfaces degrade under thermal cycling, or chemical loading. Moreover, the reliability of thermal interfaces can be especially problematic when the interconnecting area is large, which increases its predisposition to generate defects (voids, delamination, or nonuniform quality) during processing. In order to improve the quality of the bonding process, as well as to be able to accurately assess interface reliability, it would be desirable to have a simple, reliable, and nondestructive measurement technique that would prod

Resumen

The magnitudes and relative pressure distributions transmitted to the crosstie-ballast interface of railroad track significantly influences the subsequent behavior and performance of the overall track structure. If the track structure is not properly designed to distribute the heavy-axle loads of freight cars and locomotives, deficiencies and inherent failures of the crossties, ballast, or underlying support layers can occur, requiring substantial and frequent maintenance activities to achieve requisite track geometrical standards. Incorporating an understanding of the pressure distribution at

Resumen

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>This article presents a measurement system based on the RS-485 interface. The presented system is an alternative solution for distributed measurement systems, which cannot be built using IEEE-488 interface due to distance limitation between elements of the system. The RS-485 interface is a base for communication between measurement instruments and uses a Master-Slave protocol to exchange data between them. One dedicated master device, usually a PC, controls all sl
