INEQUALITY AND PUBLIC POLICY: THEORETICAL INVESTIGATIONS Caution is required, however, in
generalizing from this chapters results to choice markets that do not link school assignment
to residential location. Under Tiebout choice, parents may have to give up desired
neighborhood amenitiesviews, parks, air quality, or characteristics of neighborsto obtain
a more effective school.
This paper presents empirical studies and closely corresponding theoretical models of the performance of a chart parser exhaustively parsing the Penn Treebank with the Treebank’s own CFG grammar. We show how performance is dramatically affected by rule representation and tree transformations, but little by top-down vs. bottom-up strategies.

A natural next step in the evolution of constraint-based grammar formalisms from rewriting formalisms is to abstract fully away from the details of the grammar mechanism--to express syntactic theories purely in terms of the properties of the class of structures they license.
Model-theoretic semantics provides a computationally attractive means of representing the semantics of natural language. However, the models used in this formalism are static and are usually infinite. Dynamic models are incomplete models that include only the information needed for an application and to which information can be added. Dynamic models are basically approximations of larger conventional models, but differ is several interesting ways. The difference discussed here is the possibility of inconsistent information being included in the model. ...
We analyze estimation methods for DataOriented Parsing, as well as the theoretical criteria used to evaluate them. We show that all current estimation methods are inconsistent in the “weight-distribution test”, and argue that these results force us to rethink both the methods proposed and the criteria used.
We use multiple views for cross-domain document classiﬁcation. The main idea is to strengthen the views’ consistency for target data with source training data by identifying the correlations of domain-speciﬁc features from different domains. We present an Information-theoretic Multi-view Adaptation Model (IMAM) based on a multi-way clustering scheme, where word and link clusters can draw together seemingly unrelated domain-speciﬁc features from both sides and iteratively boost the consistency between document clusterings based on word and link views. ...
We present a game-theoretic model of bargaining over a metaphor in the context of political communication, ﬁnd its equilibrium, and use it to rationalize observed linguistic behavior. We argue that game theory is well suited for modeling discourse as a dynamic resulting from a number of conﬂicting pressures, and suggest applications of interest to computational linguists.
Model-theoretic pragmatics is an attempt to provide a formal description of the pragmatics of natural language as effects arising from using model-theoretic semantics in a dynamic environment. The pragmatic phenomena considered here have been variously labeled ~resupposition [I] and eonven¢ional implicature . The models used in traditional model-theoretic semantics provide a complete and static representation of knowledge about the world, llowever, this is not the environment in which language is used. ...
Research purpose: Clarifying theoretical issues and practice of the theoretical thought development of the commissars of the Vietnam People's Army; on that basis, to propose basic solutions of theoretical thought development of the commissars in order to meet the requirements, responsibilities and assigned tasks.
Computational fluid dynamics (CFD) is concerned with the efficient numerical solution of the partial differential equations that describe fluid dynamics. CFD techniques are commonly used in the many areas of engineering where fluid behavior is an important factor. Traditional fields of application include aerospace and automotive design, and more recently, bioengineering and consumer and medical electronics.
Research purpose: The thesis clarifies fundamental theoretical matters and the real situation of the education and training to the development of hight-quality human resources; recommends a number of directions and solutions to bring into full play the role of education and training in the development of hight-quality human resources in Vietnam at present.

The second edition of "Model Predictive Control" provides a thorough introduction to theoretical and practical aspects of the most commonly used MPC strategies. It bridges the gap between the powerful but often abstract techniques of control researchers and the more empirical approach of practitioners. The book demonstrates that a powerful technique does not always require complex control algorithms. Many new exercises and examples have also been added throughout.
In the early 19th century, the French mathematician Jean-Baptiste Fourier states that:
Any periodic waveform can be expressed as the sum of sine waves with frequencies at integer or
harmonic multiples of the fundamental frequency of the waveform and with appropriate maximum
amplitudes and phases.
Theoretical analysis and computational modeling are important tools for
characterizing what nervous systems do, determining how they function,
and understanding why they operate in particular ways. Neuroscience
encompasses approaches ranging from molecular and cellular studies to
human psychophysics and psychology. Theoretical neuroscience encourages
cross-talk among these sub-disciplines by constructing compact representations
of what has been learned, building bridges between different
levels of description, and identifying unifying concepts and principles.
Understanding and quantitative describing of marine ecosystems requires an integration
of physics, chemistry and biology. The coupling between physics, which
regulates for example nutrient availability and the physical position of many organisms
is particularly important and thus cannot be described by biology alone.
Therefore the appropriate basis for theoretical investigations of marine systems are
coupled models, which integrate physical, chemical and biological interactions.
The book "Polycrystalline Materials - Theoretical and Practical Aspects" is focused on contemporary investigations of plastic deformation, strength and grain-scale approaches, methods of synthesis, structurals, properties, and application of some polycrystalline materials. It is intended for students, post-graduate students, and scientists in the field of polycrystalline materials.
