This paper provides an overview of the power, packaging, and cooling aspects of the IBM eServer z900 design. The semiconductor processor chips must be supported and protected in a mechanical structure that has to provide electrical interconnects while maintaining the chip junction temperature within specified limits. The mechanical structure should be able to withstand shock and vibrations duri...

Acoustical signals from mechanical systems reveal the operating conditions of mechanical components and thus benefit for machinery condition monitoring and fault diagnosis. However, the acoustical signals directly measured by the sensors in essential are the mixed signals of all the sources, and normally it is very difficult to be used for source identification or operating feature extraction. ...

the ip lookup process is a key bottleneck in routing due to the increase in routing table size, increasing traıc and migration to ipv6 addresses. the ip address lookup involves computation of the longest prefix matching (lpm), which existing solutions such as bsd radix tries, scale poorly when traıc in the router increases or when employed for ipv6 address lookups. in this paper, we describe a ...
