Japanese scientists have developed a statistical program that could enable portable baby-monitoring devices to determine whether infant cries mean a baby is sleepy, hungry, needs a change, or is in pain. Tomomasa Nagashima and colleagues at the Muroran Institute of Technology used a sound pattern recognition strategy to analyze infants’ crying patterns. The team analyzed the frequency of cries and the power function of the audio spectrum to classify different types of crying. Nagashima and colleagues were able to correlate the different recorded audio spectra with the emotional state of a baby as confirmed by the parents. Recordings of a crying baby with a painful genetic disorder helped the researchers differentiate the cries of babies who are in pain. They were able to achieve a 100 percent success rate in classifying pained cries and normal cries via their technique.

The flagging attraction of science, technology, engineering, and math (STEM) professions to young women is partly attributed to the geek factor, or the perception of such careers as uncool, socially isolating, and primarily geared toward males. The National Center for Women & Information Technology estimates that about 17 percent of high school girls take advanced computer science placement exams, which represents the lowest percentage of females among all such tests. Meanwhile, the number of women earning computer science degrees fell from 37 percent in 1985 to 18 percent in 2008. AT&T Labs researcher Amanda Stent says that “a movement to reclaim the notion of ‘geek’ ” is underway to reverse this trend, and she is a member of a group dedicated to encourage more young women to become passionate about science and technology. Stent stresses that engineers, technologists, and scientists often work in groups and invent community-building, societally beneficial products.

The Partnership for Advanced Computing in Europe’s work package for future petaflop computer technologies beyond 2010 recently assessed 12 prototypes for next-generation computer architectures. The evaluation included full systems, system components, software prototypes, and several research activities. For example, CINES and LRZ jointly evaluated a hybrid system containing both thin and fat nodes and compute accelerators within a shared file system. NCF assessed a system of ClearSpeed/PetaPath accelerator boards together with the ClearSpeed programming language. CEA looked at the performance of graphics processing units (GPUs) using CAPS hybrid multicore parallel programming. The CSC studied the maturity of OpenCL and performance improvements for multi-GPU programming on NVIDIA Tesla and AMD Firestream cards. CSCS evaluated the PGAS programming model using the Cray Compiler Environment for UPC and CAF. And EPCC evaluated the HARWEST Compiling Environment for developing programs on the FPGA-based Maxwell supercomputer.
