We study a 1D transport equation with nonlocal velocity and show the formation of singularities in ﬁnite time for a generic family of initial data. By adding a diﬀusion term the ﬁnite time singularity is prevented and the solutions exist globally in time. 1. Introduction In this paper we study the nature of the solutions to the following class of equations (1.1)
Human cystatin C (HCC) is a family 2 cystatin inhibitor of papain-like
(C1) and legumain-related (C13) cysteine proteases. In pathophysiological
processes, the nature of which is not understood, HCC is codeposited in
the amyloid plaques of Alzheimer’s disease or Down’s syndrome.
We have attempted to explain the concepts which have been used and
developed to model the stochastic dynamics of natural and biological systems.
While the theory of stochastic differential equations and stochastic processes
provide an attractive framework with an intuitive appeal to many problems
with naturally induced variations, the solutions to such models are an active
area of research, which is in its infancy. Therefore, this book should provide
a large number of areas to research further.

We demonstrate a system for ﬂexible querying against text that has been annotated with the results of NLP processing. The system supports self-overlapping and parallel layers, integration of syntactic and ontological hierarchies, ﬂexibility in the format of returned results, and tight integration with SQL. We present a query language and its use on examples taken from the NLP literature.
The paper begins by defining a class of distributed memory machines which have useful properties as retrieval and filtering devices. These memory mechanisms store large numbers of associations on a single composite vector. They provide a natural format for encoding the syntactic and semantic constraints associated with linguistic elements. A computational architecture for parsing natural language is proposed which utillses the retrieval and associative features of these devices.
This paper describes Subcat-LMF, an ISOLMF compliant lexicon representation format featuring a uniform representation of subcategorization frames (SCFs) for the two languages English and German. Subcat-LMF is able to represent SCFs at a very ﬁne-grained level. We utilized SubcatLMF to standardize lexicons with largescale SCF information: the English VerbNet and two German lexicons, i.e., a subset of IMSlex and GermaNet verbs. To evaluate our LMF-model, we performed a crosslingual comparison of SCF coverage and overlap for the standardized versions of the English and German lexicons.
The current state-of-the-art in statistical machine translation (SMT) suffers from issues of sparsity and inadequate modeling power when translating into morphologically rich languages. We model both inﬂection and word-formation for the task of translating into German. We translate from English words to an underspeciﬁed German representation and then use linearchain CRFs to predict the fully speciﬁed German representation. We show that improved modeling of inﬂection and wordformation leads to improved SMT. ...
INKA is a natural language interface to facilitate knowledge acquisition during expert system development for electronic instrument trouble-thooting. The expert system design methodology develops a domain definition, called GLIB, in the form of a semantic grammar. This grammar format enables GLIB to be used with the INGLISH interface, which constrains users to create statements within a subset of English. Incremental patting in INGLISH allows immediate remedial information to be generated if a user deviates from the sublanguage.
In smaller regions such as the Carpathian Basin (located in Eastern/Central Europe), 50 km
horizontal resolution may still not be appropriate to describe the meso-scale processes (e.g.,
cloud formation and convective precipitation). For this purpose on a national level several
RCMs have been adapted with finer resolution (25 and 10 km). Here, results from two of the
adapted RCMs for Hungary are analyzed, namely, models PRECIS and RegCM.
In this paper, first, data and models from PRUDENCE, PRECIS and RegCM are presented.
The manner in which paint films are formed is determining for many of the key
properties of a paint film. This is the reason why paints are often classified according
to their film formation principles.
Due to the success of the first edition of
The Engineering Handbook
published in 1995 I am pleased to
provide the second edition ten years later fully updated and expanded.
The purpose of
The Engineering Handbook, Second Edition
is to provide in a single volume a ready
reference for the practicing engineer in industry, government, and academia. The book in its comprehensive
format is divided into 30 sections which encompass the field of engineering and includes 19
brand new chapters and 131 fully updated contributions.
The world’s climate is changing, and it will continue to change throughout the 21st century and beyond. Rising temperatures, new precipitation patterns, and other changes are already affecting many aspects of human society and the natural world. Climate change is transforming ecosystems at extraordinary rates and scales.
The aim of the study was to investigate the crystallization kinetics and solidification
behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification
behaviour in near-equilibrium and non-equilibrium cooling conditions was studied.
The eutectic and peritectic reactions were found to exist in the solidification
sequence of the alloy. The bulk metallic glass formation was achieved by using two
methods: quenching from the liquid state and quenching from the semi-state.
In the a-posteriori (post-hoc, natural or market defined) approach of market segmen-
tation, market segments are identified by forming groups of consumers that are inter-
nally homogeneous and externally heterogeneous along a set of measured consumer
characteristics ( segmentation variables). That is, a-posteriori market segments are
based on responses of consumers that are available only after a survey has been con-
Chemical precipitation and complexation are primarily important for the inorganic species.
The formation of coordination complexes is typical behaviour of transition metals, which
provide the cation or central atom. Ligands include common inorganic anions such as Cl
as well as organic molecules such as amino acids. Such
complexation may facilitate the transport of metals.
Biodegradation is a reaction process mediated by microbial activity (a biotic reaction).
Where the possibilities of a man reached the end, especially from the point of view of
technical solutions, the nature took over and formed our environment according to its
needs. Nowadays technical and engineering activities have a significantly greater
impact on the natural laws and rules once considered as changeless. Nonetheless we
have been approaching the same pattern that we followed in the past – we get inspired
by the nature.
The imagination is questionable (Daily, 1997; Dasgupta, 2000b). In any event, we should
be sceptical of a theory which places such enormous burden on an experience not much more
than two hundred years old (Fogel, 1994; Johnson, 2000). Extrapolation into the past is a
sobering exercise: over the long haul of history (some five thousand years), economic growth
even in the currently-rich countries was for most of the time not much above zero.
This report has five chapters: Chapter 1 outlines its contents; Chapter 2 describes the institutional framework for environmental protection in Vietnam; Chapter 3 focuses on the social environment; Chapter 4 discusses the natural environment in the study area; and Chapter 5 assesses the environmental aspects for the feasibility studies. For the social environment context, the resettlement issue is analyzed in Chapter 4. The environmental impact assessment (EIA) was prepared in a different format.
