Navigation has added interactivity in nowadays multimedia applications which support effective accessing to objects of various formats and presentation requirements. Storage issues need to be reconsidered for the new type of navigational multimedia applications, in order to improve system’s performance. This paper addresses the problem of multimedia data storage towards improving data accessibi...

The properties of hierarchical solid acid materials have been explored combining experimental catalysis findings, neutron scattering and positron lifetime spectroscopy to understand the multi-porous nature these materials.

Multimedia data storage is a critical issue in large scale applications. This paper proposes a frequency based multimedia data representation model which effectively guides data storage and elevation among the secondary and tertiary storage levels. Multimedia data are stored on the tertiary storage level and (based on certain popularity criteria) they are elevated on secondary level towards imp...

Public transit plays a key role in shaping the transportation structure of large and fast growing cities. To cope with high population and employment density, such cities usually resort to multi-modal transit services, such as rail, BRT and bus. These modes are strategically connected to form an effective transit network. Among the transit modes, bus stops need to be properly deployed to mainta...

Predicting novel cleavage sites for HIV-1 protease in non-viral proteins is a difficult task because of the scarcity of previous cleavage data on proteins in a native state. We introduce a three-level hierarchical classifier which combines information from experimentally verified short oligopeptides, secondary structure and solvent accessibility information from prediction servers to predict po...

BACKGROUND Access to varied, healthy and inexpensive foods is an important public health concern that has been widely documented. Consequently, there is an increasing interest in identifying food deserts, that is, socially deprived areas within cities that have poor access to food retailers. In this paper we propose a methodology based on three measures of accessibility to supermarkets calculat...

Aiming at the current imperfect hierarchical diagnosis and treatment system unreasonable spatial distribution of medical facilities. This article introduces 2SFCA model improved by Gaussian distance decay function multiple stage radius to evaluate accessibility facilities in Wuhan. The results indicate that: firstly, compared with traditional model, is more sensitive identification accessibilit...

A facile approach to functionalize carbon nanofibers [CNFs] with nanostructured polyaniline was developed via in situ mechanochemical polymerization of polyaniline in the presence of chemically treated CNFs. The nanostructured polyaniline grafting on the CNF was mainly in a form of branched nanofibers as well as rough nanolayers. The good dispersibility and processability of the hybrid nanocomp...

MOTIVATION A recently developed DNaseI assay has given us our first genome-wide view of chromatin structure. In addition to cataloging DNaseI hypersensitive sites, these data allows us to more completely characterize overall features of chromatin accessibility. We employed a Bayesian hierarchical change-point model (CPM), a generalization of a hidden Markov Model (HMM), to characterize tiled mi...
