The growing demand for complex and minimally invasive surgical interventions is driving the search for ways to use computer-based information technology as a link between the pre-operative plan and the tools utilized by the surgeon. Computers, used in conjunction with advanced surgical assist devices, will fundamentally alter the way that are procedures are carried out in 21st Century operating...

Application console logs are a ubiquitous tool for diagnosing system failures and anomalies. While several techniques exist to interpret logs, describing and assessing log quality remains relatively unexplored. In this paper, we describe an abstract graphical representation of console logs called the identifier graph and a visualization based on this representation. Our representation breaks lo...

harvesting of timber using ground based machinery is still a common practice around the world. track and road building, and movement of machinery during harvesting operations cause soil disturbance. therefore the aim of this study was to investigate the change in soil properties after logging operation on skid trails (2 years and 7 years after logging) and compare disturbed soil properties with...

Most database systems use ARIES-like logging and recovery scheme to recover from failures and guarantee transactional consistency. ARIES relies on the Write-Ahead Logging (WAL) protocol which requires that log records be written durably prior to the corresponding data changes. In order to enforce WAL, database systems rely on the write-through capability of the storage media. While SCSI disks t...

The current energy saving technologies rely on conventional data logging systems, where the current methods in retrieving the energy data is not convenient, and the cost of the data logging systems is high. The Automatic energy Meter Reading (AMR) technology is network-based applications used by electric/energy companies to increase performance and reliability of their energy meter reading and ...

Background: Software developers insert log statements in the source code to record program execution information. However, optimizing the number of log statements in the source code is challenging. Machine learning based within-project logging prediction tools, proposed in previous studies, may not be suitable for new or small software projects. As these software projects do not have sufficient...

This paper presents region-based storage management schemes, which support the efficient implementation of checkpointing and message logging for fault tolerant mobile computing systems. In the proposed schemes, a recovery manager assigned for a group of cells takes care of the recovery for the mobile hosts within the region. As a result, the recovery information of a mobile host, which may be d...

An important set of challenges emerge as the High Performance Computing (HPC) community aims to reach extreme scale. Resilience and energy consumption are two of those challenges. Extreme-scale machines are expected to have a high failure frequency. This is an inevitable consequence of the mismatch between two trends. The number of components assembled in supercomputers grows exponentially. How...

Logging user interactions is fundamental to capturing and subsequently analysing behaviours in the context of web-based Interactive Information Retrieval (IIR). However, logging often implemented within experimental apparatus a piecemeal fashion, leading incomplete or noisy data. To address these issues, we present LogUI framework. We use (now ubiquitous) contemporary web technologies provide a...
