For a user who is unfamiliar with a target domain, the first step to conduct an exploratory search task is to go over a learning phrase, which means to learn from the search results to acquire basic domain knowledge. Since lots of search results could be returned by a search engine, and usually...

A mean flow acoustic engine based on the aerodynamic effects converts wind energy and fluid energy in pipelines into acoustic energy which can be used to drive thermoacoustic refrigerators and transducers without any mechanical moving parts. A mean flow acoustic engine with the resonator tube...

A thermoacoustic compressor is capable of converting an alternating gas flow to a direct one with a large pumping rate on the basis of the pressure oscillation nature of thermoacoustic engines and the flow rectification effect of check valves. Theoretical calculations are first carried out to...

Purpose: The purpose of this paper is to measure the degree of interdisciplinary collaboration in Big Data research based on the co-occurrences of subject categories using Stirling’s diversity index and specialization index. Design/methodology/approach: Interdisciplinarity was measured...

This paper investigates the changing roles played by liquidity constraint and uncertainty in accounting for the dynamism of Chinese household consumption behaviour. Starting from the Euler equation-based model of Robert Hall, a framework encompassing an array of consumption models is developed...
