The Descartes Query Language (DQL) enables to query the performance of a system using adapters to various solution approaches. Thereby, DQL is a realization of the vision of Declarative Performance Engineering (DPE) which decouples the description of user concerns (performance questions and goals) from the task of selecting and applying a specific solution approach. While model-based approaches...

In this paper a new query answering system is presented for querying knowledge bases in the Semantic Web. The implementation follows the DAML+OIL Query Language Abstract Speci cation (DQL) and supports acyclic conjunctive queries. The system uses a Description Logic (DL) reasoner to answer the queries and the conjunctive queries are transformed into DL retrieval or boolean queries. After the in...

A novel type of 2-(un)substituted phenyl-2,3-dihydroquinazolin-4(1H)-one (DQL) derivatives were designed and synthesized to study the impact of halogen substituents on interactions between DQL and human serum albumin (HSA) by comparison methodology. The interactions between DQL and HSA were studied by fluorescence spectroscopy. The intrinsic fluorescence of human serum albumin was quenched by D...

This poster describes the DQL language : a new XML data manipulation language. DQL is an extension of OQL for the manipulation of tree-like and forest-like data. It integrates XPath location paths and provides us with the classical SQL operators and some specific tree transformation operators. The first version of DQL has been implemented in Java using the DOM and the SAX API’s.

The economic impact of anthelmintic resistance was investigated in lambs by comparing productivity parameters in groups of animals treated either with a highly effective anthelmintic, or an anthelmintic to which three species of resistant worms were known to be present. Ten farmlets, each stocked with 30 lambs, were rotationally grazed for 5 months, with monthly treatments of either albendazole...

INTRODUCTION The aim of the study was to develop a Polish version of the Diabetes Quality of Life Brief Clinical Inventory (DQL-BCI) and to perform validating evaluation of selected psychometric aspects. MATERIAL AND METHODS The translation process was performed in accordance with generally accepted international principles of translation and cultural adaptation of measurement tools. Two hund...

Research in NMR has focused largely on the idea of representing knowledge about the world via rules that are generally true but can be defeated. Even if relational databases are nowadays the main tool for storing very large sets of data, the approach of using non-monotonic formalisms as relational database query languages has been investigated to a much smaller extent. In this work we propose a...

Multipath TCP (MPTCP) has emerged as a facilitator for harnessing and pooling available bandwidth in wireless/wireline communication networks data centers. Existing implementations of MPTCP such as, Linked Increase Algorithm (LIA), Opportunistic LIA (OLIA) BAlanced LInked Adaptation (BALIA) include separate algorithms congestion control packet scheduling, with pre-selected parameters. We propos...

The Palladio Bench is a tool to model, simulate and analyze Palladio Component Model (PCM) instances. However, for the Palladio Bench, no single interface to automate experiments or Application Programming Interface (API) to trigger the simulation of PCM instances and to extract performance prediction results is available. The Descartes Query Language (DQL) is a novel approach of a declarative ...
