Software agents will personalize smart devices to act autonomously on behalf of their human owner. In dynamical electronic commerce environments, these agents could buy and sell goods and services from each other, without using a central market maker. From a system perspective, this creates a decentralized and continuously changing multi-agent system with the need for coordination of supply and...

A wide array of dynamic bandwidth allocation (DBA) mechanisms have recently been proposed for improving bandwidth utilization and reducing idle times and packets delays in passive optical networks (PONs). The DBA evaluation studies commonly assumed that the report message for communicating the bandwidth demands of the distributed optical network units (ONUs) to the central optical line terminal...

Data integration involves merging two or more schemas into a global schema based on the identification of common concepts, and also the set of different concepts that are mutually related by some semantic properties. Identifying semantic relationships that exist between a set of objects in one schema and a different set of objects in another schema is crucial to the integration process. Earlier...

Abstract Introduction One third of birthing parents experience insomnia symptoms during perinatal periods. Cognitive Behavioural Therapy for Insomnia (CBT-I) is effective insomnia. However, it unclear how adherence to and perceived usefulness individual CBT-I components predict treatment efficacy. Methods 76 nulliparous (age M±SD=33.07±3.10) with prenatal received from two randomised controlled...

Automated performance tuning of data management systems offer various benefits such as improved performance, declined administration costs, and reduced workloads to database administrators (DBAs). Currently, DBAs tune the performance of database systems with a little help from the database servers. In this paper, we propose a new technique for automated performance tuning of data management sys...

The purpose of this study was to compare the efficacy of individual and group cognitive behavioral therapy for insomnia (CBT-I) in outpatients with primary insomnia diagnosed by DSM-IV-TR. The participants were 20 individually treated (I-CBT-I) and 25 treated in a group therapy format (three to five patients per group) (G-CBT-I), which showed no significant difference regarding demographic vari...

Borderline personality disorder (BPD) has been associated with maladaptive cognitive processes including dysfunctional attitudes and a negative attribution style. Comorbid insomnia affects the course of multiple psychiatric disorders, and has been associated with the absence of recovery from BPD. Because dysfunctional beliefs and attitudes are common among patients with insomnia, the purpose of...

As an increasing amount of XML data is being exchanged between Web applications, reliable XML storage systems that make this data persistent and process it efficiently are becoming necessary. The flexibility of representation offered by XML raises challenging issues when storing XML data in relational or object systems. Major database vendors: IBM, Microsoft and Oracle provide a declarative map...

STUDY OBJECTIVES This study examines the relevance of self-reported morning and evening chronotypes in treatment-seeking insomniacs presenting to a tertiary sleep clinic setting. DESIGN Using a cross-sectional design, patients were categorized as morning, intermediate, and evening chronotypes based upon scores on the Morningness-Eveningness Composite Scale (MECS). Group comparisons were made ...
