To investigate the drive-mode resonance frequency of a micromachined vibratory gyroscope (MVG), one needs to measure it accurately and efficiently. The conventional approach to measure the resonant frequency is by performing a sweep frequency test and spectrum analysis. The method is time-consuming and inconvenient because of the requirements of many test(More)
Inspired by the framework of Boyen, in this paper, an attribute-based signature (ABS) scheme from lattice assumption is proposed. In this attribute-based signature scheme, an entity’s attributes set corresponds to the concatenation of a lattice matrix with the sum of some random matrices, and the signature vector is generated by using the Preimage Sampling(More)
Recently, location-based services (LBSs) have been increasingly popular for people to experience new possibilities, for example, personalized point-of-interest (POI) recommendations that leverage on the overlapping of user trajectories to recommend POI collaboratively. POI recommendation is yet challenging as it suffers from the problems known for the(More)
Key-dependent message (KDM) security is an important security issue that has attracted much research in recent years. In this paper, we present a new construction of the symmetric encryption scheme in the the ideal cipher model (ICM); we prove that our scheme is KDM secure against active attacks with respect to arbitrary polynomialtime challenge functions.(More)
a r t i c l e i n f o JEL classification: C22 E44 F31 Keywords: Monetary shocks Asymmetric effects MSVAR–EGARCH In this paper, we study the effect of monetary shocks on the Chinese stock market over the period of 2005 to 2011 with the MSVAR–EGARCH model. The evidence suggests that Chinese monetary policies have significantly asymmetric effects on the stock(More)
High-accuracy railway track surveying is essential for railway construction and maintenance. The traditional approaches based on total station equipment are not efficient enough since high precision surveying frequently needs static measurements. This paper proposes a new filtering and smoothing algorithm based on the IMU/odometer and landmarks integration(More)
Based on the reference model of the multiplication removal quick second-order low-pass filter and state machine implementation through timing sequence instruction, the paper proposes the designing method of the state machine for multi-frequency point IIR low-pass digital filter. Thus, it sets to meet the requirements of multi-frequency and quick filtering(More)
