1 Introduction Oracle Database has matured over many years, and current releases support a rich set of features that greatly expand database functionality and improve performance. Fortunately, increased functionality has not led to greater complexity – each new major release of Oracle Database has featured fewer tunables thanks to automatic tuning of database instances. Management of the System...

Complex sleep behaviors (CSBs) are often associated with hypnotics use. This study aimed to investigate the prevalence and correlates of CSBs among individuals who were taking flunitrazepam from psychiatric outpatient clinics. A total of 268 participants who were administered flunitrazepam for at least 3 months were enrolled from psychiatric outpatient clinics from June 2011 to May 2012. The o...

Over the past 30 years, several large integral facilities have been utilized in order to understand transient behavior in nuclear power plants. The main objective of these integral facilities was to enhance our physical understanding of transient phenomena during LOCA or non-LOCA transients. An integral database was also used as a basis for the development and verification of thermal hydraulic ...

One of the most challenging tasks for the database administrator is physically designing the database (by selecting design features such as indexes, materialized views, and partitions) to attain optimal performance for a given workload. These features, however, impose storage and maintenance overhead on the database, thus requiring precise selection to balance the performance and the overhead. ...

In this paper we discuss advances in self-tuning database systems over the past decade, based on our experience in the AutoAdmin project at Microsoft Research. This paper primarily focuses on the problem of automated physical database design. We also highlight other areas where research on self-tuning database technology has made significant progress. We conclude with our thoughts on opportunit...

We have reviewed the literature on the performance of high efficiency particulate air (HEPA) filters under normal and abnormal conditions to establish criteria for calculating the efficiency of HEPA fitters in a DOE nonreactor nuclear facility during and after a Design Basis Accident (DBA). The literature review included the performance of new filters and parameters that may cause deterioration...
