The time required for recovery from a failure is heavily influenced by hardware setup and workload characteristics. In bad but still realistic cases, the recovery required during restart can take hours. For a database system based on write-ahead logging, we performed a qualitative study of how hardware and software configurations affect the behavior of the database and, consequently, how this b...

In this position paper, we propose to investigate novel technologies for evaluating information visualization systems: physiological sensing. We review existing technologies and describe how advances in physiological sensing open a novel perspective for the evaluation of information visualization systems.

Animal-mediated seed dispersal is important for sustaining biological diversity in forest ecosystems, particularly in the tropics. Forest fragmentation, hunting, and selective logging modify forests in myriad ways and their effects on animal-mediated seed dispersal have been examined in many case studies. However, the overall effects of different types of human disturbance on animal-mediated se...

With a gigabyte of memory priced at less than $2,000, the main-memory DBMS (MMDBMS) is emerging as an economically viable alternative to the disk-resident DBMS (DRDBMS) in many problem domains. The MMDBMS can show significantly higher performance than the DRDBMS by reducing disk accesses to the sequential form of log writing and the occasional checkpointing. Upon the system crash, the recovery ...

The porosity of a zone can be estimated either from a single “porosity log” (sonic, density, neutron, or magnetic resonance log) or a combination of porosity logs, in order to correct for variable lithology effects in complex reservoirs. In the carbonates, mineral mixtures are primarily drawn from calcite, dolomite, and quartz (either as sand grains or as chert); anhydrite and gypsum may also o...

Fehlmann and King introduce bio-logging techniques to track free-living animals.
