OBJECTIVE To examine the effect of Seventh-day Adventist (SDA) membership on 'immunity' to the secular effects of changes in BMI. DESIGN Three independent, cross-sectional, screening surveys conducted by Sydney Adventist Hospital in 1976, 1986 and 1988 and a survey conducted among residents of Melbourne in 2006. SUBJECTS Two hundred and fifty-two SDA and 464 non-SDA in 1976; 166 SDA and 291...
Traditional speech enhancement algorithms consider speech detection and estimation process independently. The simultaneous detection and estimation approach (SDA) combines both detection and estimation processes to reduce the effects due to missed detection. SDA is based on an estimator which minimizes bayesian risk with the aid of minimum mean square error (MMSE) estimator. The MMSE estimator ...
This paper presents an innovative approach to model validation for a structure with significant parameter variations. Model uncertainty of the structural dynamics is quantified with the use of a singular value decomposition technique to extract the principal components of parameter change, and an interval model is generated to represent the system with parameter uncertainty. The coordinate vect...
Proper orthogonal decomposition is a statistical pattern analysis technique for "nding the dominant structures, called the proper orthogonal modes, in an ensemble of spatially distributed data. While the proper orthogonal modes are obtained through a statistical formulation, they can be physically interpreted in the "eld of structural dynamics. The purpose of this paper is thus to provide some ...
Over the last decades, Morocco has been facing increasingly severe water scarcity. To quantify use in Morocco, we refer to footprint (WF) concept, including both direct and indirect use. WF considered covers internal exported virtual (VW). We used input-output structural decomposition analysis (SDA) quantitatively analyze drivers of changes Morocco’s sectoral from 1995 2015. The mechanisms gove...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
This study developed and validated a new measure to assess the death anxiety (i.e., Scale of Death Anxiety, SDA) on an individual's somatic, cognitive, emotional, and behavioral reactions from a symptomatic perspective in Chinese youth samples. Following a systematic process, a four-factor structure of the SDA was identified through principle components analysis and confirmatory factor analysis...
With frequent climate change related disaster shocks and a huge burden of refugees from neighbor country’s conflict, Bangladesh needs to formulate effective strategies support its most prospective sectors for ensuring sustainable development. This paper aims at disentangling the process economic growth in identify some accelerating sectors, which could achieve constant with proper policy suppor...
Turkey’s CO2 emissions have been steadily increasing since the 1990s. Determining influences of socioeconomic factors behind this increase can help identify which sectors and what types policies should be prioritized to go into action. This paper identifies main contributors change within five-year intervals during 1990-2015 by adopting Structural Decomposition Analysis (SDA) method. The result...
Household consumption has become an important field of carbon dioxide emissions. Urban–rural disparity in the household emissions (HCEs) residents and their influencing factors are relevant to HCE reduction. Taking Fujian as study area, LMDI SDA models were used analyze effects for direct (DHCEs) indirect (IHCEs) urban rural from 2006 2018. The HCEs continue rise, approximately 65% IHCEs 2017, ...
