We present an intercomparison of several aerosol modules, sectional and modal, in a global 2-D model in order to differentiate their behavior for tropospheric and stratospheric applications. We model only binary sulfuric acidwater aerosols in this study. Three versions of the sectional model and three versions of the modal model are used to test the sensitivity of background aerosol mass and si...

According to the great importance of safety in aerospace industries, identification of dynamic parameters of related equipment by experimental tests in operating conditions has been in focus. Due to the existence of noise sources in these conditions the probability of fault occurrence may increases. This study investigates the effects of noise in the process of modal parameters identification b...

Objective: To test the effect of a 16-week multi-modal exercise program on neurocognitive and physical functioning and brain-derived neurotrophic factor (BDNF). Design: A single-blinded, parallel-group randomised controlled trial. Settings: University campus and community based halls. Subjects: Forty-nine women aged 65 and 75 years, with no cognitive impairment and not undertaking more than one...

The rapid development of multimodal transportation system prompts travellers to choose multiple transportation modes, such as private vehicles or taxi, transit (subways or buses), or park-and-ride combinations for urban trips. Traffic corridor is a major scenario that supports travellers to commute from suburban residential areas to central working areas. Studying their modal choice behaviour i...

Watching a speaker say words benefits subsequent auditory recognition of the same words. In this study, we tested whether hearing words also facilitates subsequent phonological processing from visual speech, and if so, whether speaker repetition influences the magnitude of this word repetition priming. We used long-term cross-modal repetition priming as a means to investigate the underlying lex...

This study develops a novel balancing method named as Low-Speed Holo-Balancing (LSHB), which can balance the flexible rotor without test run at high speeds. The principle of LSHB is mainly based on the holospectrum technique with following specialties. Firstly, the vibration response of rotor is described by three-dimensional holospectrum using multi-sensor fusion, instead of information from a...

the problem of crack identification in continuous beam like structures is considered. the cracks’ locations and their depths are identified by employing experimental modal test results performed on the structure. the cracks are modeled using generic elements to include the coupling effects between shear forces and bending moments at the crack section. in the identification procedure eigen- sens...

We study a modal logic of knowledge and action, focussing on test actions. Such knowledge-gathering actions increase the agents’ knowledge. We propose a semantics, and associate an axiomatics and a rewriting-based proof procedure.

The notions of meta-ontology enhance the ability to process knowledge in information systems; in particular, ontological property classification deals with the kinds of properties in taxonomic knowledge based on a philosophical analysis. The goal of this paper is to devise a reasoning mechanism to check the ontological and logical consistency of knowledge bases, which is important for reasoning...
