Normal language user’s word-association intuition (e.g. drunken – stagger) raises questions about the mental lexicon organization and its application for natural language processing tasks. We present an automatic contextually related words (contexonym) organizing model (ACOM) that reflects this intuition, giving one of the possible answers to this question. Trained on large corpora, the model (...

Algorithms for tracking concept drift are important for many applications. We present a general method based on the Weighted Majority algorithm for using any on-line learner for concept drift. Dynamic Weighted Majority (dwm) maintains an ensemble of base learners, predicts using a weighted-majority vote of these “experts”, and dynamically creates and deletes experts in response to changes in pe...

This report contains a description of a large three-stage ~ompressnr whloh has been designed fnr detail thrco dimensional flow investlgat~ons. Particular attention has been pad to the accuracy of measurement on the ng and it 1s shown that the mzin errors are due to the unsteady nature of the flow and to speed fluctuations. Both of these factors are, however, consderably less than those nomm.Uy ...

Lateral InGaAs quantum dot molecules (QDMs) formed by partial-cap and regrowth technique exhibit two ground-state (GS) peaks controllable via the thicknesses of InAs seed quantum dots (x), GaAs cap (y), and InAs regrowth (z). By adjusting x/y/z in a stacked QDM bilayer, the GS peaks from the two layers can be offset to straddle, stagger, or join up with each other, resulting in multi-GS or broa...

This paper presents a GaAs-based Ka-band low noise amplifier (LNA) with gain flatness enhancement. Active device optimization and inductive degeneration techniques were employed to obtain figure (NF) good input/output return loss. In order achieve flat response over wide bandwidth, the stagger tuning technique was utilized. The proposed LNA implemented by 0.15 μm GaAs pHEMT process, chip area i...

statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...

the normal carrying angle in shiraz population was measured on the basis of sex and age. the right elbow angle of 4266 cases was examined from birth to 30 years old. this study found the carrying angle in 2540 females to be 7.20 (range 2-19) and in 1726 males to be 6.40 (range 2-11), a 0.80 difference. a significant difference (p= 0.05) was found in relation to age. there is a gradual increase ...
