There appears to be a preference for pesticide sprayed onto plants deposited in larger quantities at leaf tips than other parts of plants. However, there is no clear experimental evidence explain this phenomenon. Based on previous studies, the possible mechanisms phenomenon include aerodynamics, microstructure surface and elasticity. Three experiments were carried out an attempt explore main fa...

this paper studies the dynamic behavior of price elasticity and its effects on the overall profit. although price elasticity has a significant effect on sales, its dynamics have not been examined so far in pricing models. in this paper, a simple pricing model is suggested in which, price elasticity is considered dynamic. the suggested pricing model is concerned with a monopolist that its object...

One of the major challenges in cloud computing is to simplify the monitoring and control of elasticity. On the one hand, the user should be able to specify complex elasticity requirements in a simple way and to monitor and analyze elasticity behavior based on his/her requirements. On the other hand, supporting tools for controlling and monitoring elasticity must be able to capture and control c...

We consider general homogeneous Agmon-Douglis-Nirenberg elliptic systems with constant coefficients complemented by the same set of boundary conditions on both sides of a crack in a two-dimensional domain. We prove that the singular functions expressed in polar coordinates (r; ) near the crack tip all have the form r 12+k'( ) with k 0 integer, with the possible exception of a finite number of s...

Conditions for which strain-based and stress-based failure criteria are mathematically equivalent in elastic media are explored by expressing the criteria in the spectral eigenspace of the elasticity tensor. For scalar-valued quadratic criteria that are homogeneous functions of degree one, stressbased and strain-based criteria are most likely to be mathematically equivalent when the criteria’s ...

Lundbaek et al. estimated the ratio of the volume of the lipid and the decane annulus VH to the aqueous volume VA as VH/VA ≈ 0.001. The hydrocarbon/aqueous partition coefficient K gives the ratio of concentration of bioflavinoid in hydrocarbon cH to its aqueous concentration cA as cH/cA=K. Therefore, the ratio of the amount of bioflavinoid in the hydrocarbon region BH to the amount in the aqueo...

 County-level housing net worth shock: We cannot make the exact county-level housing net worth shock used in our analysis publicly available given restrictions in our agreements with Equifax and CoreLogic. However, we can make a CBSA-level data set available that replaces Equifax debt with county-level debt from the Federal Reserve Bank of New York, and replaces CoreLogic house price growth fr...

This paper uses a general equilibrium model to study the source and reward of asymmetric volatility or skewness of market returns in an exchange economy. In particular, the dividend growth rate is modeled as a stochastic volatility process and the representative agent is characterized by Epstein-Zin preferences. The equilibrium equity premium, risk-free rate, and asymmetric volatility (measured...

Compositional data, containing relative information, occur regularly inmany disciplines and practical situations. Multivariate statistics methods including regression analysis have been adopted to model compositional data, but the existing research is still scattered and fragmented. This paper contributes to modeling the linear regression relationship for compositional data as both dependent an...

The present study examines the degree to which income distribution affects the ability of economic growth to reduce poverty, based on 1990s data for a sample of rural and urban sectors of African economies. Using the basic needs approach, an analysis-ofcovariance model is derived and estimated, with the headcount, gap and squared gap poverty ratios serving as the respective dependent variables ...
