An image retrieval system is a computer system for browsing, searching and retrieving images from a large database of digital images. Given a textual query in traditional text based image retrieval (TBIR),relevant images are to be re ranked using visual features after the initial text based image search. In this paper, we propose a new bag based re ranking framework for large scale TBIR. We com...

A new concept of a high-frequency amplitude detector and demodulator for Giant-Magneto-Impedance (GMI) sensors is presented. This concept combines a half wave rectifier, with outstanding capabilities and high speed, and a feedback approach that ensures the amplitude detection with easily adjustable gain. The developed detector is capable of measuring high-frequency and very low amplitude signal...

در این پژوهش، تغییرات زمانی تپ‌های لیزری 2CO TEA که از اتاقکی حاوی گاز 6SF با فشار mbar 150-10 عبور می‌کند، شاریدگی‌های انرژی و فشارهای گازی مختلف بررسی شده است. نشان داده است برای هر شاریدگی، قطع معینی وجود دارد قطع، میخه تپ به طور کامل حذف می‌شود، درحالی دنباله دربرگیرنده کسر قابل توجهی اولیه آن است، برجامی‌ماند. شواهد تجربی برآمده داده‌های بیناب‌سنجی FTIR، گسست چندفوتونی مولکول‌های را پاسخگو...

Computer aided image analysis systems for radiographic inspection (X-ray or gamma ray) are among the most commonly used Non-destructive Evaluation (NDE) methods. The accuracy of these systems is very much depending on the selected features which are extracted from weld defect images. In this paper, we firstly introduce a computer aided image analysis system for X-ray image inspection and evalua...

A b s t r a c t T h e structural gene (/3GALA) coding for lysosomal t3-galactosidase-A (EC 3.2.1.23) has been assigned to human chromosome 3 using man-mouse somatic cell hybrids. Human t3-galactosidase-A was identified in cell hybrids with a species-specific antiserum to human liver/3-galactosidase-A. The antiserum precipitates fl-galactosidase-A from human tissues, cultured cells, and cell hyb...

Recent advances on the understanding of valid inequalities from the infinite group relaxation has opened the possibility of finding a computationally effective extension to GMI cuts. In this paper, we investigate the computational impact of using a subclass of minimally-valid inequalities from this relaxation on a wide set of instances.

Abstract. A new atmospheric ozone profile climatology has been constructed by combining daytime profiles from the Aura Microwave Limb Sounder (MLS) and Modern-Era Retrospective Analysis for Research Applications version 2 (MERRA-2) Global Modeling Initiative (GMI) model simulation (M2GMI). The MLS M2GMI are merged between 13 17 km (?159 88 hPa), with used stratospheric GMI primarily tropospheri...
