This paper proposed a novel method to enhance mammogram images used in detecting early signs of breast cancer. The proposed method uses a three level pyramid decomposition scheme that applies the squeeze box filter (SBF) instead of low-pass filtering. A previously proposed non-linear local enhancement technique is applied to the difference images to contrast enhance the structural details of a mammogram...
HP has recently made its plans to develop an ultrahigh-resolution seismic sensing solution public. This solution is being developed with Royal Dutch Shell Corporation for oil and gas exploration. Central to delivering this system is HP's new single axis seismic grade MEMS accelerometer. The HP device uses both bulk micromachining methods and standard thin film technologies as well as HP's new three...
In semiconductor manufacturing processes, mixed-products are usually fabricated on the same set of process tool with different recipes. Run-to-run controllers which based on the exponential weighted moving average (EWMA) statistic are probably the most frequently used in industry for the quality control of certain semiconductor manufacturing process steps. However, for mixed-product drifting process,...
Charge Coupled Devices (CCDs) have been successfully used in several high energy physics experiments over the past two decades. Their high spatial resolution and thin sensitive layers make them an excellent tool for studying shortlived particles. The Linear Collider Flavour Identification (LCFI) Collaboration has been developing Column-Parallel CCDs for the vertex detector of a future Linear Collider...
Sb-heterostructure backward diodes have proven to be a strong contender for millimeter-wave direct detection applications, primarily due to their high sensitivity, low noise and high frequency response. It has been shown that thinning the AlSb barrier thickness (from 32 A to 11 A) greatly reduced the junction resistance (Rj) and thus the associated Johnson noise. However this lowered the curvature...
The state of the art in millimeter-wave detection and imaging using Sb-heterostructure detectors has been advanced recently with demonstration of excellent low-noise performance through the use of very thin (< 15 Aring) tunnel barriers. This reduction in tunnel barrier thickness improves the noise by reducing the thermal noise associated with the junction resistance, Rj. However, the thinner barrier...
