Multistep processing is commonly used for nearest neighbor (NN) and similarity search in applications involving high-dimensional data and/or costly distance computations. Today, many such applications require a proof of result correctness. In this setting, clients issue NN queries to a server that maintains a database signed by a trusted authority. The(More)
Recently, with the fast development of sensing and wireless communication technology, wireless sensor networks (WSNs) have been applied to monitor the physical world. A WSN consists of a set of sensor nodes, which are small sensing devices with limited computational resources able to communicate with each other located in their radio range. Network(More)
Phishing is a popular technique to thieve user's authentication information, especially password. The key issue is that it is difficult for user to distinguish fake login user interface (LUI) from normal LUI. This paper introduces a novel method to anti-phish by smart device. In our method, a smart device pre-stores feature information of LUI. Before(More)
In this paper, we propose an image-based collision detection optimization algorithm in order to meet the high requirements of real-time and accuracy in the increasingly complex collision detection environment. The algorithm can deal with arbitrary model and will make efficient use of the GPU on the basis of RECODE and RAPID algorithm. In this paper, the(More)
An actinomyce (S07) isolated from a cyst of Heterodera filipjevi was characterised as Streptomyces anulatus by morphological, physiological and biochemical criteria and 16S rRNA analysis. The biocontrol potential of S07 was evaluated against both Heterodera avenae and H. filipjevi. After an initial assay of S07 culture filtrates on egg hatch in vitro and(More)
The Collared Scops Owl (Otus bakkamoena) is not sexually dimorphic, which makes it difficult to discriminate between sexes. Hence, it is difficult to establish a breeding and conservation program. This study report, the identification of a novel random amplified polymorphic DNA (RAPD) marker for sexing the species O. bakkamoena. A novel 1,307-bp(More)
In a wireless sensor network (WSN), each sensor monitors environmental parameters, and reports its readings to a base station, possibly through other nodes. A sensor works in cycles, in each of which it stays active for a fixed duration, and then sleeps until the next cycle. The frequency of such cycles determines the portion of time that a sensor is(More)
