A method is proposed to invert displacement and tilt measurements from a single monitoring location to constrain the nature of a volcanic pressure source. Evolutionary strategy is applied to a sequence of Mogi solutions and the program is shown capable of distinguishing between depth and volume increment of the magma source, in addition to its 3-dimensional spatial coordinates. The mechanism is...

Previous research has shown that hills appear steeper to those who are fatigued, encumbered, of low physical fitness, elderly, or in declining health (Bhalla & Proffitt, 1999; Proffitt, Bhalla, Gossweiler, & Midgett, 1995). The prevailing interpretation of this research is that observers' perceptions of the environment are influenced by their capacity to navigate that environment. The current s...

Introduction: Lunar regolith breccias provide direct samples of the complicated, highly mixed nature of the Moon’s near-surface environment. By understanding their makeup it is hoped to be able to extrapolate to how large-scale remote-sensing datasets will detect geochemical information from a mixture of different lunar lithological terranes. Discussed here is an investigation into three lunar ...

Serological proteome analysis (SERPA) combines classical proteomic technology with effective separation of cellular protein extracts on two-dimensional gel electrophoresis, western blotting, and identification of the antigenic spot of interest by mass spectrometry. A critical point is related to the antigenic target characterization by mass spectrometry, which depends on the accuracy of the mat...

In this paper, an effective numerical method is introduced for the treatment of nonlinear two-dimensional Volterra-Fredholm integro-differential equations. Here, we use the so-called two-dimensional block-pulse functions.First, the two-dimensional block-pulse operational matrix of integration and differentiation has been presented. Then, by using this matrices, the nonlinear two-dimensional Vol...

Most research on ad-hoc wireless networks makes simplifying assumptions about radio propagation. The “Flat Earth” model of the world is surprisingly popular: all radios have circular range, have perfect coverage in that range, and travel on a two-dimensional plane. CMU’s ns-2 radio models are better but still fail to represent many aspects of realistic radio networks, including hills, obstacles...

This paper develops a method for analyzing the change of surface, a continuous function defined over the two-dimensional space. The surface change is represented by a scalar field in a spatio-temporal region. The region is divided into subregions called hills and waves which are based on the local form of the surface. They are both threedimensional tessellations of the spatio-temporal region, a...

Internal waves (IWs) generated by tidal flow over the seafloor play a critical role in ocean circulation and climate. We determine the dependence of the radiated IW power on topographic parameters in numerical simulations of tidal flow over two-dimensional random topographic profiles that have the spectrum of oceanic abyssal hills. The IW power increases as the horizontal spatial resolution sca...
