Asymmetry, Zero Morphology and Tractability

چکیده
We present a theory of grammar based on asymmetrical relations, the Strict Asymmetry Theory, and we provide evidence form Indo-European and non Indo-European languages to show that argument structure restrictions on morphological composition follow in a principled way from the theory. We describe and implement a bottom-up parser for morphological selection in the Strict Asymmetry framework. Core lexical properties including argument structure and derivational affix selection are encoded in a uniform mechanism. We consider the computational implications of three different implementations. In particular, we examine the effect on bottom-up parsing from varying the Specifier-Head-Complement order. We provide computational motivation for the logical separation of overt and covert affixation.

On the numerical solution of integral equations of the fourth kind with higher index: differentiability and tractability index-3
In this paper, we consider a particular class of integral equations of the fourth kind and show that tractability and differentiability index of the given system are 3. Tractability and dierentiability index are introduced based on the-smoothing property of a Volterra integral operator and index reduction procedure, respectively. Using the notion of index, we give sucient conditions for the exi...
متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
متن کاملUniform Weak Tractability of Multivariate Problems
In this dissertation we introduce a new notion of tractability which is called uniform weak tractability. We give necessary and sufficient conditions on uniform weak tractability of homogeneous linear tensor product problems in the worst case, average case and randomized settings. We then turn to the study of approximation problems defined over spaces of functions with varying regularity with r...
متن کاملTractability properties of the weighted star discrepancy
Tractability properties of various notions of discrepancy have been intensively studied in the last decade. In this paper we consider the so-called weighted star discrepancy which was introduced by Sloan and Woźniakowski. We show that under a very mild condition on the weights one can obtain tractability with s-exponent zero (s is the dimension of the point set). In the case of product weights ...
متن کاملModeling the Effects of Geometric Asymmetry on Aero-heating of the Ablative Noses
noses by using the equivalent axisymmetric body (EAB) theory. This Code has been developed by researchers and the results of it have been validated by the various flight tests results. In the case of non-zero angle of attack or asymmetric surface ablation for each meriodinal plane, the equivalent meriodinal plane (EMP) is created for any meriodinal plane. The combinations of these planes consti...
