The problem of defining robot behaviors to completely address a large and complex set of situations is very challenging. We present an approach for robot’s action selection in the robot soccer domain using Case-Based Reasoning techniques. A case represents a snapshot of the game at time t and the actions the robot should perform in that situation. We basically focus our work on the retrieval an...

Clustered distributed storage models real data centers where intraand cross-cluster repair bandwidths are different. In this paper, exact-repair minimum-storage-regenerating (MSR) codes achieving capacity of clustered distributed storage are designed. Focus is given on two cases: = 0 and = 1/(n−k), where is the ratio of the available crossand intra-cluster repair bandwidths, n is the total numb...

Patterned magnetic nanowires are extremely well suited for data storage and logic devices. They offer non-volatile storage, fast switching times, efficient operation and a bistable magnetic configuration that are convenient for representing digital information. Key to this is the high level of control that is possible over the position and behaviour of domain walls (DWs) in magnetic nanowires. ...

Storage-class memory (SCM) combines the benefits of a solidstate memory, such as high performance and robustness, with the archival capabilities and low cost of conventional hard-disk magnetic storage. Such a device would require a solid-state nonvolatile memory technology that could be manufactured at an extremely high effective areal density using some combination of sublithographic patternin...

With emerging storage-class memory (SCM) nearing commercialization, there is evidence that it will deliver the muchanticipated high density and access latencies within only a few factors of DRAM. Nevertheless, the latency-sensitive nature of in-memory services makes seamless integration of SCM in servers questionable. In this paper, we ask the question of how best to introduce SCM for such serv...

The study of distributed memory systems has produced a number of models which work well in limited domains. However, until recently, the application of such systems to realworld problems has been difficult because of storage limitations, and their inherent architectural (and for serial simulation, computational) complexity. Recent development of memories with unrestricted storage capacity and e...

The maintenance of data warehouses(DWs) is becoming an increasingly important topic due to the growing use, derivation and integration of digital information. Most previous work has dealt with one centralized data warehouse only. In this paper, we now focus on environments with multiple DWs that are possibly derived from other DWs. In such a large-scale environment, data updates from base sourc...

As the number and variety of files stored and accessed by a typical user has dramatically increased, existing file system structures have begun to fail as a mechanism for managing all of the information contained in those files. Many applications—email clients, multimedia management applications, and desktop search engines are examples— have been forced to develop their own richer metadata infr...

Recently researchers have studied various approaches on how to reduce energy consumption of server-class disk storage devices. Although many studies have claimed success, details of their experimental setups are either little documented or not designed to measure power consumption or performance of their systems simultaneously. This thesis describes a new framework that produces accurate result...

Data-protection class workloads, including backup and long-term retention of data, have seen a strong industry shift from tape-based platforms to disk-based systems. But the latter are traditionally designed to serve as primary storage and there has been little published analysis of the characteristics of backup workloads as they relate to the design of disk-based systems. In this paper, we pre...
