This paper describes an approach to monitoring events on a large number of servers and workstations. While modern UNIX systems are capable of logging a variety of information concerning the health and status of their hardware and operating system software, they are generally not configured to do so. Even when this information is logged, it is often hidden in places that are either not monitored...

Groundwater transport in crystalline rocks follows pathways along fractured zones because of low primary porosity and permeability such formations. Fractured systems encompass an imbricated set joints fractures with different lengths, apertures orientations resulting complex permeable heterogeneous groundwater properties. Geophysical well logging has proved effectiveness detecting depth levels ...

Deterministic execution of parallel applications can be enforced by logging speculative memory accesses and restoring saved state in the event of a conflict. However, logging all accesses has a prohibitive overhead. We propose three techniques to reduce logging in an always-on transactional memory system. The first, Threaded Section Analysis, statically determines when only a single thread is r...

We have implemented the Grand Unified Logging Project, GULP, a flexible aggregation system for authentication log data. The system merges disparate logs stored across various servers into a single format according to an XML schema. This single format is logged to a database and queried via a web interface. The strength of this system lies in the ability to correlate information across multiple ...

In a case study a University class undertook a translation from Swedish to English in a keystroke logging environment and then replayed their translations in pairs while discussing their thought processes when undertaking the translations, and why they made particular choices and changes to their translations. Computer keystroke logging coupled with peer-based intervention assisted the students...

Understanding the causes underlying changes in species diversity is a fundamental pursuit of ecology. Animal species richness and composition often change with decreased forest structural complexity associated with logging. Yet differences in latitude and forest type may strongly influence how species diversity responds to logging. We performed a meta-analysis of logging effects on local specie...

We have proposed n-GLL+PL+stg method in order to make the parallel directory structure, Fat-Btree, reliable. The n-GLL+PL+stg combines a staggered data allocation, global logging, and physiological logging. In this paper, we discuss a case in which neighbor-WAL protocol is applied to the Fat-Btree so that the performance of the transaction processing can be improved without reducing its high re...

Throughout human history, slow-renewal biological resource populations have been predictably overexploited, often to the point of economic extinction. We assess whether and how this has occurred with timber resources in the Brazilian Amazon. The asynchronous advance of industrial-scale logging frontiers has left regional-scale forest landscapes with varying histories of logging. Initial harvest...
