Online social networks (OSNs) suffer from the creation of fake accounts that introduce fake product reviews, malware and spam. Existing defenses focus on using the social graph structure to isolate fakes. However, our work shows that Sybils could befriend a large number of real users, invalidating the assumption behind social-graph-based detection. In this(More)
Biochips have been an advanced technology for biomedical applications since the end of the 20th century. Optical detection systems have been a very important tool in biochip analysis. Microscopes are often inadequate for high resolution and big view-area detection of microarray chips, thus some new optical instruments are required. In this work, a novel(More)
In the fast evolving wireless communication system, Software Defined Radio (SDR) has emerged as a feasible solution to overcome the compatibility issue of various communication standards. There is a pressing need to have stable, low-cost, open platforms to support the configurable and standard (restriction) free architecture. The goal of SDR perfectly(More)
Hyperthermia is a type of cancer treatment in which body tissue is exposed to high temperatures. Research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues. In the clinical application of hyperthermia, three methods can be distinguished: local, regional and whole-body hyperthermia. Hyperthermia(More)
This paper enhances the author's previous work with adding memory and other methods to SOFM recognition system to speed up the process and improve the accuracy of the automatically recognition. The focus of this research is the various M-ary QAM and PSK modulated signal formats subjected to data contamination by noise and fading. Distinguish from other(More)
There are facts suggesting that the changes of excitability of neurons and conductance of synapses are responsible for learning and memory. In accordance with the idea, the author proposed a neuronal network model of associative memory, which can learn conditioned reflexes repeatedly together with its adaptive properties, without much interference with the(More)
A high-frequency and micro-amplitude vibration based micromanipulator is proposed, which is composed of a micro-motion parallel mechanism having three pure translational degrees of freedom and a micro-vibration unit having one degree of freedom. The micro-vibration unit is fixed on movable platform of the parallel mechanism, and an glass operational needle(More)
DigiraI Video Broadcasting for Handhelds (DVB-H) is the latest DVB standardfrom the DVB Group targeting handheld, battery powered devices such as mobjle telephones, PDAs(Persona1 Digital Assistants). etc. DVB-H enables IP data services including low definition TV services to be received on battery powered handheld terminals. Time Division Multiplexing (TOM,(More)
This paper studies the feasibility of using UML in software defined radio (SDR). The contributions of the study are in three areas: 1) SDR is used as an example to elaborate the UML for hardware software co-design in embedded communication system. A hybrid UML design approach for the SDR open architecture, SCA, is elaborated in the paper. 2) Some compiler(More)
