SIREn: Entity Retrieval System for the Web of Data

We present ongoing work on the Semantic Information Retrieval Engine (SIREn), an “entity retrieval system” specifically designed to meet the requirements of indexing and searching a large amount of semi-structured data, e.g. the entire Web of Data. SIREn supports efficient full text search with semi-structural queries and exhibits a concise index, constant time updates and inherits Information ...

Siren Song of Segmentation

The Siren Organ

Sirens evoke images of alarm, public service, war, and forthcoming air raid. Outside of the music of Edgard Varése ([8], [9]), sirens have rarely been framed as musical instruments. By connecting air hoses to spinning disks with evenly-spaced perforations, the siren timbre is translated musically. Polyphony gives our instrument an organ-like personality: keys are mapped to different frequencies...

Analysis of Emergency Department Queue System Performance: Simulation Approach Based on Experiment Design

Background: Simulation is an appropriate technique for analyzing and evaluating the dynamic behavior of complex systems. The present study aimed to develop an integrated model using a simulation approach based on designing experiments to analyze performance of the admission queue system of patients, who referred to the emergency department of the Modarres hospital. Methods: In this descriptive...

SIREN - A Network Infrastructure for Emergencies

In emergencies or disasters a key support factor for situation awareness, decision making and response is to provide a secure and dependable network infrastructure that aggregates connectivity over all available heterogeneous wireless broadband access technologies, including those employed for commercial network access. The infrastructure must be able to adapt to mission critical application re...
