With the increase in automation and use of computer control in machine tools, the number of cutting tools per machining setup is on the increase. On one hand, such multi-tool setups offer the advantages of reduced down-time and cost of production and require less space and in-process inventory, and on the other hand, require proper tool management for economic operations. A number of strategies...

State machine replication is a common approach for building fault-tolerant services. A Replicated State Machine (RSM) typically uses a consensus protocol such as Paxos [1] to decide on the order of updates and thus keep replicas consistent. Using Paxos, the RSM can continue to process new requests, as long as more than half of the replicas remain operational. If this bound is violated, however,...

Assessment of Machine Learning Approaches to Predict in-Hospital Mortality in Patients Underwent Prosthetic Heart Valve Replacement Surgery

Classifier ensembles is an active area of research within the machine learning community. One of the most successful techniques is bagging, where an algorithm (typically a decision tree inducer) is applied over several different training sets, obtained applying sampling with replacement to the original database. In this paper we define a framework where sampling with and without replacement can...

As streaming media over the Internet becomes popular, caching proxy has become increasingly important. Nowadays, caching proxy has turned into a standard technique, which is widely deployed on the Internet to reduce client-perceived delay and network traffic. In this paper, we propose a cluster-based streaming caching proxy architecture in which the local network has a number of independent cac...

abstract background: esophageal replacement is indicated in certain circumstances including long gap esophageal atresia, severe strictures due to gastro-esophageal reflux (ger) and caustic burns. we analyzed our results of 18 patients who underwent esophageal replacement in our university hospital. methods: we reviewed esophageal replacements carried out in our department between june 1996 and ...

COMA machine is similar to that in a traditional shared memory machine, there are a few aspects that differentiate the AMs from the cache memory in traditional cache-coherent multiprocessors [8]. One important aspect unique to COMA is that the backing store of the AMs in a COMA machine is disks of secondary storage. So, unlike a traditional multiprocessor cache, write-back to the backing store ...
