	1. Secure Data Aggregation for Internet of Things

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Internet of Things has received more and more attention, due to a wide range of potential applications. In this paper, we propose a secure data aggregation framework for the Internet of Things. It is based on fully homomorphic encryption. It is a form of encryption where any specific algebraic operation performed on the plaintext is equivalent to the same algebraic operation performed on the ciphertext.

	Abstract:At the basis of the adaptive lifting wavelet transform, a method was proposed for solving the problem of noise suppression of the wire rope damage signals. A wavelet with damage property was constructed via lifting scheme, that is,the adaptive update-filter and the adaptive predict-filter were designed using the statistics information of the wire rope damage signals. And the compromise algorithm between software-threshold and hard-threshold was used in the threshold processing. The traditional wavelet and the above proposed transform are applied in de-noising of the practical acquisition of wire rope damage signal. The contrast experiments show that the noise elimination with the improved lifting scheme is better than that achieved by traditional wavelet transform. Moreover, this presented scheme retains the effective information in the break signals and greatly improves the design flexibility and the process speed.

	3. Building Inspection in Diagnostic Engineering

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Diagnostic engineering involves diagnosis of faults, examination and interpretation of defects, investigation of malfunctions, introduction and operation of condition monitoring – and numerous related activities. Diagnostic engineers require knowledge of many disciplines and an understanding of the operating principles of machine, instruments, controls; of strengths and functional capabilities. In particular, professional diagnostic skills are needed to compare the behaviour of a contraption when ‘in health’ with what it does when in ‘distress’. Then, the diagnostic engineer can do something to improve less-favorable condition.
