Cost-Efficient Open Source Desktop Size Radial Stretching System With Force Sensor

A Low Cost/Low Power Open Source Sensor System for Automated Tuberculosis Drug Susceptibility Testing

In this research an open source, low power sensor node was developed to check the growth of mycobacteria in a culture bottle with a nitrate reductase assay method for a drug susceptibility test. The sensor system reports the temperature and color sensor output frequency change of the culture bottle when the device is triggered. After the culture process is finished, a nitrite ion detecting solu...

A Low Cost Three-directional Force Sensor

In this work a low cost sensor has been developed to measure three-directional forces. The theory, design and sensor construction details are presented. It was constructed by using commercial strain gauges. Finite element method was adopted to optimize the structure dimensions, and improve the sensitivity of force sensor by distributing the sensing stress on the maximum strain positions. A hard...

Open Acquisition: Combining Open Source Software Development with System Acquisition

This study explores and develops concepts leading to the combination of best practices from open source software development (OSSD) projects with emerging capabilities for virtual system acquisition. Virtual system acquisition is an evolving approach to demonstrate significant improvements in reducing the cost and cycle time for acquiring software-intensive systems, while improving their qualit...

The Equivalent Force System of a Monopole Source in a Fluid-filled Open Borehole

The elastodynamic body-wave field outside a fluid-filled open borehole due to a monopole source in the fluid, is reduced to the radiation-field due to a suitable equivalent force system (EFS) in the absence of the borehole, consisting of a monopole plus a vertical dipole. Theoretical seismograms of the EFS displacements in the solid are shown to be in excellent agreement with those obtained fro...
