Magnetic flux leakage (MFL) testing is a widely used technology for detecting structural defects in industry, where new magnetic sensors can provide an enhanced detectability. We have fabricated and developed vortex tunnel junctions (MTJs) into MFL probe, by designing well-balanced gradiometer with base length of 4 cm. Such has exhibited field detectability 1.6nT/Hz at 1 kHz, superior common-mo...

In Case-Based Reasoning and in Machine Learning, an important concept is the similarity metric (or measure), a function which rates how similar two objects are, according to some criteria. We concentrate here on case-base queries – finding a case in a case-base which most resembles some probe case. Selecting what metrics are most appropriate is a key part of both designing, and using, a case-base.

When designing micro-scale tactile probes, a design trade-off must be made between the stiffness and flexibility of the probing element. The probe must be flexible enough to ensure sensitive parts are not damaged during contact, but it must be stiff enough to overcome attractive surface forces, ensure it is not excessively fragile, easily damaged or sensitive to inertial loads. To address the n...

BACKGROUND Fiber-based optical spectroscopy has been widely used for biomedical applications. However, the effect of probe-sample distance on the collection efficiency has not been well investigated. METHOD In this paper, we presented a theoretical model to maximize the illumination and collection efficiency in designing fiber optic probes for biomedical spectra measurement. This model was in...

in this study, a cylindrical bolling probe was developed and evaluated for measuring stress in soil under tire traffic. the probe consists of a silicon rubber head for sensing the soil stress, a pvc tube for transferring the liquid pressure, a digital pressure sensor and a syringe for filling the probe with water and adjusting the initial inclusion pressure. a tank with pressurized air was used...

Background A rapid, accurate, flexible and reliable diagnostic method may significantly decrease the costs of diagnosis and treatment. Designing an appropriate microarray chip reduces noises and probable biases in the final result. Objective The aim of this study was to design and construct a DNA Microarray Chip for a rapid detection and identification of 10 important bacterial agents. Meth...

XML itself does not support hypermedia, but the XLink standard has been defined to make XML usable for hypermedia. One of XLinks most interesting features is its support for external links and linkbases, which makes it possible to create links between resources without having to change the resources. In order to use these links, user agents must access linkbases and query them for relevant link...

the goal of this study was to compare the effect of heater probe thermocoagulation for massive bleeding of peptic ulcers with a control group. between march 1992 and august 1995 we used heater probe thermocoagulation endoscopically to treat 42 patients with active ugl bleeding or nonbleeding visible vessels at the base of ulcer craters within 2-3 hours of admission. we also selected 42 patients...
