Variable fixing is an important technique when solving combinatorial optimization problems. Unique profitable variable values are detected with respect to the objective function and to the constraint structure of the problem. Relying on that specific structure, effective variable fixing algorithms (VFAs) are only suited for the problems they have been designed for. Frequently, new combinatorial...

Information Retrieval (IR) and Answer Extraction are often designed as isolated or loosely connected components in Question Answering (QA), with repeated overengineering on IR, and not necessarily performance gain for QA. We propose to tightly integrate them by coupling automatically learned features for answer extraction to a shallow-structured IR model. Our method is very quick to implement, ...

This study presents a designing process for refurbishing of a 32 MW rotor-generator damaged coupling. The reason of rotor damage was being hit by the quivers of an explosion. The original coupling was union with the rotor formed after a machining process on a mono block forged rotor. In some areas imposed damages caused the breaking off and detachment of some parts in the coupling flange. Becau...

Visual data-mining strategy lies in tightly coupling the visualizations and analytical processes into one data-mining tool that takes advantage of the strengths from multiple sources. This paper presents concrete cooperation between automatic algorithms, interactive algorithms and visualization tools. The first kind of cooperation is an interactive decision tree algorithm called CIAD+. It allow...

We investigated age-related changes in electroencephalographic (EEG) coupling of theta-, alpha-, and beta-frequency bands during bottom-up and top-down attention. Arrays were presented with either automatic "pop-out" (bottom-up) or effortful "search" (top-down) behavior to younger and older participants. The phase-locking value was used to estimate coupling strength between scalp recordings. Be...

Purpose: The aim of the current study was to investigate the effectiveness of schema therapy and mindfulness based cognitive therapy on the rate of using negative automatic thoughts in women with major depression in Mashhad. Participants were 36 depressed women clients, randomly selected and randomly designated to 3 groups (two experimental group and control group). Materials and method: This s...

800x600   introduction:  many items are needed for dressing including sterile dressing set, antiseptic and washing solutions, leucoplast tape, waste bin for infectious garbage, waste bin for noninfectious garbage, safe disposal trash for sharp cutting instruments, bedpan and sometimes drugs. all the items are laid out on a simple wheeled trolley. the multiplicity of items together with problems...

An automatic artificial intelligence (AI)-driven design procedure for mutual coupling reduction and a novel isolator are proposed frequency reconfigurable antenna array. The process is driven expedited by the parallel surrogate model-assisted differential evolution synthesis (PSADEA) method. array element can switch its operation between 2.5 GHz ISM band 3.4 WiMAX band. By introducing isolator,...

Web site summarization, which identifies the essential content covered in a given Web site, plays an important role in Web information management. However, straightforward summarization of an entire Web site with diverse content may lead to a summary heavily biased to the dominant topics covered in the target Web site. In this paper, we propose a two-stage framework for effective summarization ...
