Innovative Engine
'Innovative Engine' provides a column for NEC researchers, developers of innovative technologies discovered at NEC Central Laboratories, to introduce their work. At the end of each column there is a message from the researchers themselves. It is our hope that these messages will deepen interest in science and technology.
Speech Recognition
May.12, 2008
A number of products and solutions that use speech as an interface are appearing on the market enabling users to convert speech to text and to automatically retrieve information using speech as an alternative to text input. We introduce speech recognition technologies that provide "behind-the-scenes" support of these products.
Quality degradation analysis for large-scale networks
May.24, 2007
NEC Laboratories started to develop technologies related to "quality degradation locating for large-scale networks" over two years ago in response to society needs and the rapid introduction of VoIP equipment within enterprises. These technologies are expected to be able to quickly locate the point at which the quality of an application degrades on a large-scale network. They are thus valuable tools for recovery from network faults.
Bioplastics for Electronic Equipment
Sep.2, 2010 (4th edition)
Dr. Masatoshi Iji offers an introduction to high-safety petroleum-based flame-retardant plastics, which were the first kind environment-friendly plastics NEC worked on in the course of its development work. He then proceeds with a detailed presentation on the effort NEC has been making in recent years to develop bioplastics that are even more environment-friendly.
Quantum Computer
Aug.8, 2007 (2nd edition)
To find the prime factors of a 300-digit number, even a supercomputer would need about 10 million years. For a quantum computer, this task would take only several tens of seconds. Jaw-Shen Tsai and Yasunobu Nakamura describe the potential of quantum computers and the basic principals behind their operation.
Carbon Nanotube
Sep.25, 2007 (4th edition)
"Carbon nanotube" was discovered in 1991 by Sumio Iijima, a senior research fellow at NEC (then Chief Researcher at NEC's Fundamental Research Laboratories). NEC is conducting research and development targeting next-generation transistors using carbon nanotubes.
