An intelligent environment employing multiple vision sensors labeled with identification features is proposed. The union of the sensing ranges of these vision sensors covers a large unknown workspace where a mobile robot can proceed to explore. The goal of this research is to accomplish mobile robot localization and navigation based on such a calibration-free sensor network. Specifically, stati...
Genomewide Analysis of Carotenoid Cleavage Dioxygenases in Unicellular and Filamentous Cyanobacteria
Carotenoid cleavage dioxygenases (CCDs) are a group of enzymes that catalyze the oxidative cleavage steps from carotenoids to various carotenoid cleavage products. Some ccd genes have been identified and encoded enzymes functionally characterized in many higher plants, but little in cyanobacteria. We performed a comparative analysis of ccd sequences and explored their distribution, classificati...
Colony collapse disorder (CCD) is characterized by the unexplained losses of large numbers of adult worker bees (Apis mellifera) from apparently healthy colonies. Although infections, toxins, and other stressors have been associated with the onset of CCD, the pathogenesis of this disorder remains obscure. Recently, a proteomics study implicated a double-stranded DNA virus, invertebrate iridesce...
A complete lattice L is constructively completely distributive CCD L if the sup map de ned on down closed subobjects has a left adjoint It was known that in boolean toposes CCD L is equivalent to CCD L We show here that the latter property for all L su ciently for characterizes boolean toposes Research partially supported by grants from NSERC Canada Diagrams typeset using catmac Introduction Th...
آشکارساز سنتیلاتوری)سوسوزن( یک آشکارساز پرتو حالت جامد است که از یک بلور سوسوزن )فسفر( برای آشکارسازی پرتو و تولید پالسهای نوری استفاده میکند. نانو فسفرهای عناصر خاکی کمیاب به دلیل مزایایی، مثل بازدهی بالای لومینسانس توجه زیادی را به عنوان آشکارسازهای پرتو ایکس، ذرات سنگین از قبیل آلفا یا پروتون و نوترونها جلب کردهاند. در میان آنها، نانو فسفر اوکسی سولفید گادولینیوم دوپ شده با تربیوم gd2o2s:t...
Radial or pincushion distortion problem of the wide angle charge-coupled device (CCD) camera is an important issue in the image calibration in case of close-up photography of real scene. We designed the auto-extraction method of the warping points in the calibration algorithm of the image acquired by the wide angle CCD camera. Proposed method extracts the distortion point by the wide angle CCD ...
background and objectives: discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, congo red, by a fungal isolate, aspergillus niger hm11. materials and methods: centra...
During the maintenance period of a future fusion reactor power plant, called DEMOnstration Power Plant (DEMO), remotely handled casks are required to confine and handle DEMO in-vessel components during their transportation between active facility. In order limit dispersion activated dust, Contamination Control Door (CCD) is designed be placed at an interface separable containments (e.g., vacuum...
