Mass multimedia data with geographical information (geo-multimedia) are collected and stored on the Internet due to wide application of location-based services (LBS). How find high-level semantic relationship between geo-multimedia construct efficient index is crucial for large-scale retrieval. To combat this challenge, paper proposes a deep cross-modal hashing framework retrieval, termed as Tr...

How do we automatically find patterns and mine data in large multimedia databases, to make these databases useful and accessible? We focus on two problems: (1) mining “uni-modal patterns” that summarize the characteristics of a data modality, and (2) mining “cross-modal correlations” among multiple modalities. Uni-modal patterns such as “news videos have static scenes and speech-like sounds”, a...

ABSTRACT This paper is organized as follows. In Section 2, we formulate the proposed UMPC method for modeling nonstationary and multi-modal data. Both MPC and UPC are shown to be special cases of the proposed UMPC model. We apply UMPC to error concealment in Section 3. The experiment results in Section 4 show the performance of UMPC for error concealment over conventional methods. We then concl...

the nonlinear static procedures (nsps) proposed by design codes do not lead to reliable results especially for tall buildings. they generally provide inconsistent estimates of inelastic seismic demands, especially for the top floors due to their inabilities in considering the higher modes effects. in this paper, a new enhanced pushover procedure is proposed which is based on the envelope of the...

In this paper, we consider the influence of trust on the assimilation of acquired information into an agent’s belief. By use of modal logic, we semantically and axiomatically characterize the relationship among belief, information acquisition and trust. The belief and information acquisition operators are respectively represented by KD45 and KD normal modalities, whereas trust is denoted by a m...

In this paper, we investigate a scheme in which the bandwidth-distance product of a multimode fiber is extended, so that it can nearly support the transmission rate of singlemode systems. Some pioneering work suggest that limited mode launch may improve the system performance by reducing the modal dispersion and increasing the system bandwidth. The scheme investigated in this paper is based on ...

In this paper we introduce global and local announcement logic (GLAL), a dynamic epistemic logic with two distinct announcement operators – [φ ]A and [φ ] − A indexed to a subset A of the set Ag of all agents – for global and local announcements respectively. The boundary case [φ ]Ag corresponds to the public announcement of φ , as known from the literature. Unlike standard public announcements...
