Quality Driven: Automotive Display Testing

Instrumentation, information, navigation and entertainment systems have moved to fully graphical, touch-enhanced displays, and customers expect the quality of these displays to be on par with that of their consumer electronics. Makers of in-vehicle displays must keep pace with improvements in display quality, increasing screen sizes, and higher resolutions. Quality inspection of these displays faces a unique set of challenges. They will be viewed in widely varied lighting and must withstand harsh environmental conditions. Detection of subtle flaws that could worsen as a result of these circumstances is critical to ensuring a high quality display throughout the lifespan of the vehicle.

Achieving Reliable Inline Measurements in Production Environments

One of the most important changes in metrology in the past few decades has been the development of portable measuring devices. This has brought inspection right to the production line, as close to the part as possible. The change—sparked by the development of portable measuring arms and the emergence of laser trackers—has turned conventional industry inspection methods completely upside down.

Can algorithms create a pop-music hit?

This week's Question: Sony Computer Science Laboratory (CSL) in Paris is developing a system of algorithms which can create songs that cater to the user's taste, based on styles adapted from existing music. Starting with a sheet-music database of more than 13,000 existing songs, users choose several titles with the sound or feel that they would like the new song to incorporate.

Python Interface to T-Matrix Scattering Computations (PyTMatrix)

PyTMatrix is a Python interface to a T-matrix numerical scattering computation code originally developed at NASA GISS (Goddard Institute for Space Studies). It integrates into the NumPy/SciPy scientific framework. The software provides streamlined access to numerical T-matrix computations directly from the Python programming language. It retains the original numerical core written in Fortran 77, thus combining the flexibility of Python and the numerical performance of Fortran. It also provides tools for post-processing the output by integrating over various particle size and orientation distributions.

System and Method for Space Utilization Optimization and Visualization

The program uses a standard Web browser to allow for visualization of an entire organization down to individual rooms.NASA’s Langley Research Center has developed a space-allocation and planning software system to allow for more effective and efficient facility usage. It also provides a customizable strategy for organizing personnel and project teams to maximize productivity and synergies among employees. Cost-reduction solutions are suggested based on organizational input constraints related to the facility. The program uses a standard Web browser to allow for visualization of an entire organization down to individual rooms. The planning tool is based on algorithms that were developed using ArcGIS software and Visual Basic codes, which enable evaluation of different space-management scenarios in real time.

Reducing Sensor and Readout Circuitry Noise in Digital Domain Using Reference Pixels

One of the main heritage tools used in scientific and engineering data spectrum analysis is the Fourier Integral Transform and its high-performance digital equivalent — the Fast Fourier Transform (FFT). The Fourier view of nonlinear mechanics that has existed for a long time and the associated FFT carry strong a-priori assumptions about the source data, such as linearity and being stationary. Natural phenomena measurements are essentially nonlinear and nonstationary.
