Web is a growing source of information. Web users surf web for different purpose. Some users surf the web to work, some for fun, students surf it for study purpose and particular users for financial information. These users visit dozen to twenty websites where they can find interesting information. Web portal is a special kind of dataintensive website that collects information from different so...

In the paper, an algorithm is proposed for improving the data association in robot visual Simultaneous Localization and Mapping (SLAM). The detection of speeded-up robust feature (SURF) is employed in the algorithm to provide a robust description for image features as well as a better representation of landmarks in the map of a visual SLAM system. Meanwhile, a likelihood-based tracking window a...

In this paper, the bee colony algorithm is used for optimizing features which have been extracted from UAV’s digital camera by SURF algorithm. To do that, the local map is stored in UAV memory before flight. During flight, images will be captured by a digital camera and the features in successive image will be extracted using SURF algorithm because SURF algorithm is considered highly insensitiv...

Recently spatio-temporal local features have been proposed as image features to recognize events or human actions in videos. In this paper, we propose yet another local spatio-temporal feature based on the SURF detector, which is a lightweight local feature. Our method consists of two parts: extracting visual features and extracting motion features. First, we select candidate points based on th...

As the pixel information of depth image is derived from the distance information, when implementing SURF algorithm with KINECT sensor for static sign language recognition, there can be some mismatched pairs in palm area. This paper proposes a feature point selection algorithm, by filtering the SURF feature points step by step based on the number of feature points within adaptive radius r and th...

Nonsense-mediated decay (NMD) is a surveillance mechanism that degrades aberrant mRNAs. A complex comprising SMG1, UPF1, and the translation termination factors eRF1 and eRF3 (SURF) is assembled in the vicinity of a premature termination codon. Subsequently, an interaction with UPF2, UPF3b, and the exon junction complex induces the formation of the decay-inducing complex (DECID) and triggers NM...

A new source-based radiometry beamline was recently constructed at the Synchrotron Ultraviolet Radiation Facility (SURF III). The goal of this beamline is to establish a national source standard with a wide spectral range from the far ultraviolet to the infrared by using the calculability of SURF III. The new beamline is a straight-through white-light beamline with few, if any, optical componen...

Inflatable Rescue Boats (IRBs) are utilised by the Surf Life Saving Association (SLSA) in Australia to perform rescue operations and in regional competitions between surf clubs. These activities have resulted in a number of serious foot and ankle injuries which reflect the high impact of this activity in heavy and unpredictable surf. We have retrospectively reviewed 12 significant injuries rela...

still remember that brief moment that revealed the astonishment of everyone in the audience. Andrew Cleland had just concluded his talk at the conference ‘Quantum Optics of Nanoand Micromechanical Systems’, which was held last July in Bad Honnef, Germany. He had taken us all by surprise. Andrew’s talk had begun as a review of recent results of his and John Martinis’ team — they had achieved an ...
