Latent heat release associated with tropical deep convective activity is investigated as a source for migrating (sun-synchronous) diurnal and semidiurnal tidal oscillations in the 80±150-km height region. Satellite-based cloud brightness temperature measurements made between 1988 and 1994 and averaged into 3-h bins are used to determine the annualand longitude-average local-time distribution of...

The article is devoted to the problems of axiology of spaces. The aim of the article is to demonstrate that a physical space is the arena of a certain struggle of values. Their materialisation and realisation in the world of real things result from the human understanding, response and approach towards values. The differences in perception of values determine a great number of spatial decisions...

This paper presents a theoretical approach to implementation of the “Multi-realization of nonlinear MIMO systems”. This method aims to find state-variable realization for a set of systems, sharing as many parameters as possible. In this paper a special nonlinear multi-realization problem, namely the multi-realization of feedback linearizable nonlinear systems is considered and an algorithm for ...

In this paper, we present the LMI conditions to characterize the strictly bounded realness of the state-space realization of the solution to the bi-tangential rational interpolation problem, i.e., they give the solution to the bitangential Nevanlinna-Pick interpolation problem [13], [3]. The bi-tangential Nevanlinna-Pick interpolation problem is the generalization of the classical interpolation...

Smooth curves and surfaces can be characterized as minimizers of squared curvature bending energies subject to constraints. In the univariate case with an isometry (length) constraint this leads classic non-linear splines. For surfaces, is too rigid a instead one asks for Willmore (squared mean curvature) energy conformality constraint. We present efficient algorithm (conformally) constrained u...

Optimal recursive decomposition (or DR-planning) is crucial for analyzing, designing, solving or finding realizations of geometric constraint sytems. While the optimal DR-planning problem is NP-hard even for general 2D bar-joint constraint systems, we describe an O(n) algorithm for a broad class of constraint systems that are isostatic or underconstrained. The algorithm achieves optimality by u...

Hartle’s generalized quantum mechanics in the sum-over-histories formalism is used to describe a nonabelian gauge theory. Predictions are made for certain alternatives, with particular attention given to coarse-grainings involving the constraint. In this way, the theory is compared to other quantum-mechanical descriptions of gauge theories in which the constraints are imposed by hand. The vanis...

A unfied theory of four-dimensional gravity together with the standard model is presented, with supersymmetry breaking of M-theory at a TeV. Masses of the known particles are derived. The cosmological constant is quantum generated to the observed value. Quantum corrections to the classical compactification are analyzed, and the scenario is stable.

This paper examines the assumption that Australian English vowel variation within urban centres is restricted to broadness variation and is a consequence of socioeconomic rather than regional factors. The acoustic structure of vowel realisations for subjects across three different regions in Sydney is compared to shed some light on the theory of regional uniformity. 95 adolescent female speaker...

Previous research on the tone system of Yucatec Maya provides contradictory accounts which this paper intends to do away with, disentangling tonal and intonational effects. The first part presents the mere realisation of lexical high and low tones, the only tonal distinction we identify for Yucatec Maya. Second, we claim that in Yucatec Maya no interaction exists between intonation and lexical ...
