We present Nodeinfo, an unsupervised algorithm for anomaly detection in system logs. We demonstrate Nodeinfo’s effectiveness on data from four of the world’s most powerful supercomputers: using logs r...
Coniform-shape tool for splitting of wooden logs
fracture mechanics wedge splitting test fracture energy
2015/5/18
The article deals with design of a coniform tool with rotary motion for splitting of logs. The tool is proposed using a fracture mechanics theory. The approach of energy balance during crack growth in...
Comparison of Chemical Compositions of Shiitake（Lentinus edodes（Berk.）Sing）Cultivated on Logs and Sawdust Substrate
shiitake log sawdust substrate proximate composition
2009/5/31
Sawdust and logs for shiitake cultivation were prepared from the same wood. Shiitake mushrooms were cultivated on the logs and on the sawdust substrate using the same mushroom seed. The proximate comp...
Comparison of Chemical Compositions of Maitake（Grifola frondosa（Fr.）S. F. Gray）Cultivated on Logs and Sawdust Substrate
Maitake mushroom log sawdust substrate
2009/5/31
Maitake mushroom was cultivated on logs and in sawdust substrate. Comparisons of proximate compositions, content of free amino acid, 5′-nucleotides and vitamin D2 were conducted. Effects of the log an...
Comparison of Wood Properties of Hinoki（Chamaecyparis obtusa）Small Diameter Logs Collected from Different Tree Ages and Heights
hinoki basic density pilodyn penetration compression strength
2009/3/6
To effectively utilize small diameter logs as a civil engineering material, the wood properties of such logs of hinoki (Chamaecyparis obtusa Endl.) were investigated by determining density of air-dri...
Influence of External Log Quality on the Presence of Knots on Sawn Faces in Sawing Medium Diameter Sugi Logs

We investigated the influence of external log quality on the presence of knots on the sawn faces through the sawing tests of medium diameter, normal quality sugi (Cryptomeria japonica D. Don) log.Whe...
Use of the Pilodyn for Estimating Basic Density and Its Applicability to Density-based Classifying of Cryptomeria japonica Green Logs
Pilodyn basic density log classification green condition Cryptomeria japonica
2009/3/6
We used a Pilodyn for estimating basic density in the green condition for the purpose of classifying logs of Cryptomeria japonica D. Don based on their density. The relationships between Pilodyn pene...
Web-Logs中连续频繁访问路径的快速挖掘算法
Web-Logs 访问路径 快速挖掘算法
2009/2/17
研究了如何从WebLogs中高效挖掘出连续频繁访问路径，提出了一种快速有效的OBMine算法。该算法借助于访问路径树进行挖掘，只需扫描一次数据库，且通过构建频繁1项集pi的HBP树，能一次性挖掘出以pi为后缀的频繁访问路径，简化了挖掘过程，实验表明在执行效率上要优于WAP算法。
