This paper presents the recent development of a next-generation wireless smart sensor (WSS) platform to enable a more accurate, inexpensive, and greatly simplified method of instrumenting structures for structural health monitoring.
Complexity relates to the intricacy of financial instrument structure, and to the composition of assets and liabilities on the balance sheet.
The instrument will be mounted behind a 1.5 m class telescope, passively cooled to 50 K, with the instrument structure and optics passively cooled to ∼ 45 K. EChO will be placed in a grand halo orbit around L2.
The instrument structure was strengthened with exploratory factor analysis, which explained 65% (sample of patients) or 57% (sample of nurses) of the variance in antecedents, 75% or 74% of the variance in activities, and 60% or 56% of the variance in the consequences of advocacy.
Because the actual instrument structure is fixed and it is hard to be changed, such as T R 1 spacing and R 1 R 2 spacing, the transmitting frequency can be easily adjusted.
Because data from the items was ordinal, the search for instrument structure employed polychoric correlations.
Instrument structure, reliability (Cronbach's a) and construct validity (convergent, discriminative, concurrent and known-groups) were assessed.
Item selection and instrument structure were based on previously published instruments used to assess the quality of full manuscripts in therapeutic trials and epidemiological research [ 11, 13- 15].
Although the instrument structure is similar with those in the Western countries, items in the HKECDS also tap culturally-sensitive expectations in each domain.
These items were subjected to Expectation Maximisation Estimation using SPSS Missing Values procedure [ 17]. Figure 1 reports the instrument structure and results of the SEM analysis.
