The work examines the nature of digital interfaces for musical expression through the use of multiple sensors, the data from which is used to generate and control multiple musical parameters in software. This enables levels of expression and diversity not generally available using conventional electronic interfaces, the latter frequently being limited to the direct control of a limited number o...

We have been developing an automated detection algorithm for masses on mammograms. There were the cases of missed detections, in most of which the masses existed around thick-mammarygland region or near chest-wall region. The purpose of this study is to develop an algorithm for detecting such masses based on a sector-shape mass-pattern model. After applying the new technique along with our prev...

We report on a novel design of an on-chip optical temperature sensor based on a Mach-Zehnder interferometer configuration where the two arms consist of hybrid waveguides providing opposite temperature-dependent phase changes to enhance the temperature sensitivity of the sensor. The sensitivity of the fabricated sensor with silicon/polymer hybrid waveguides is measured to be 172 pm/°C, which is ...

This paper, split into Parts I and II, reviews recent innovations in circuit design that have accelerated the miniaturization of sensor nodes.

In particular, Part I introduces analog circuit techniques and sensor interfaces for miniatu...

This paper deals with the design of multi-axis force (also known as force/torque) sensors, as considered within the framework of optimal design theory. Optimal design procedures consist of nding the combination of design variables that extremizes some optimality criterion: provided a suitable mathematical formulation of the problem, solutions can be e ciently obtained through currently availabl...

Measuring PCO2 (partial pressure of carbon dioxide) in an organ can enable early detection of ischemia. However, there are few clinical applicable solutions for measuring PCO2. Based upon the requirement for clinical applications, a conductivity based PCO2 sensor is proposed. A conductivity based PCO2 sensor measures conductance in an aqueous solution separated from the measured object by a gas...
