  • Abstract: In this note, we provided an improved way of constructing a LyapunovKrasovskii functional for a linear time delay system. This technique is based on the reformulation of the original system and a discretization scheme of the delay. A hierarchy of Linear Matrix Inequality based results with increasing number of variables is given and is proved to have convergence properties in terms of conservatism reduction.

  • Nanoscience has emerged to become one of the most exciting areas of research today and has attracted the imagination of a large body of students, scientists, and engineers. The various kinds of nanomaterials that one normally deals with are the zero-dimensional nanocrystals, one-dimensional nanowires and nanotubes, and two-dimensional nanofilms and nanowalls. Of these, one of the earliest research investigations pertains to nanocrystals. It is truly remarkable that Michael Faraday made nanocrystals of gold and other metals in solution way back in 1857.

  • Relation Decomposition and Insufficiency of Normal Forms (cont.): Attribute preservation condition: Each attribute in R will appear in at least one relation schema Ri in the decomposition so that no attributes are “lost”. Another goal of decomposition is to have each individual relation Ri in the decomposition D be in BCNF or 3NF. Additional properties of decomposition are needed to prevent from generating spurious tuples

  • Intellectual Property (IP) is society’s recognition of intellectual efforts. It is a monopoly granted in exchange for the contribution of intellectual creations to the society. It is an intangible property. The use of IP by a third party does not deprive the owner of his right of enjoyment. As such, an IP right is a right to restrain others from using that right. The extent of this right is dependent upon the scope of the ability granted by the law to restrain its use. The wider the scope given, the greater the monopoly an...

  • Previous studies of data-driven dependency parsing have shown that the distribution of parsing errors are correlated with theoretical properties of the models used for learning and inference. In this paper, we show how these results can be exploited to improve parsing accuracy by integrating a graph-based and a transition-based model.

  • Syntactic theories based on the concept of dependency have a long tradition. Tesni` re (Tesni` re, e e 1959) was the first who systematically described the sentence structure in terms of binary relations between words (dependencies), which form a dependency tree (D-tree for short). D-tree itself does not presume a linear order on words. However, any its surface realization projects some linear order relation (called also precedence).

  • In Information Retrieval (IR) in general and Question Answering (QA) in particular, queries and relevant textual content often significantly differ in their properties and are therefore difficult to relate with traditional IR methods, e.g. key-word matching. In this paper we describe an algorithm that addresses this problem, but rather than looking at it on a term matching/term reformulation level, we focus on the syntactic differences between questions and relevant text passages.

  • This work is concerned with the development of instruments for GB parsing. An alternative to the well known indexation system of (Chomsky, 1981) will be proposed and then used to formalize the view of Binding Theory in terms of the generation of constraints on the referential properties of the NPs of a sentence. Finally the problems of verification and satisfiability of BT will be addressed within the proposed framework.

  • Polymers present a class of materials that play a role of importance growing in catalysis. Polymeric catalysts based on polypropylene-polyacrylic acid (PP-APA) were prepared by the two methods: co-polymerization in the presence of transition metal ions (Cu(II), Fe(III), Co(II), Mn(II)…) and soaking method. Their catalytic activity was determined by oxidation reactions of ions S2- and hydroquinone by molecular oxygen in normal condition.

  • Information Extraction (IE) is a fundamental technology for NLP. Previous methods for IE were relying on co-occurrence relations, soft patterns and properties of the target (for example, syntactic role), which result in problems of handling paraphrasing and alignment of instances. Our system ARE (Anchor and Relation) is based on the dependency relation model and tackles these problems by unifying entities according to their dependency relations, which we found to provide more invariant relations between entities in many cases. ...

  • Building on work detecting errors in dependency annotation, we set out to correct local dependency errors. To do this, we outline the properties of annotation errors that make the task challenging and their existence problematic for learning. For the task, we define a feature-based model that explicitly accounts for non-relations between words, and then use ambiguities from one model to constrain a second, more relaxed model. In this way, we are successfully able to correct many errors, in a way which is potentially applicable to dependency parsing more generally. ...

When you have read this chapter, you will: understand why dependability and security are usually more important than the functional characteristics of a software system; understand the four principal dimensions of dependability, namely availability, reliability, safety, and security; be aware of the specialized terminology that is used when discussing security and dependability;...

  • Mechanical properties of film coats Michael E.Aulton SUMMARY This chapter discusses the need for a film coat to possess the correct mechanical properties. One of the requirements of a film coat is that it should provide adequate protection to the dosage form. The capacity of the film coat to afford physical protection depends to a large extent on its mechanical characteristics. After considering those desirable properties, the chapter explains how to assess such properties. It also explains the need for a standardized approach to film preparation prior to testing.

  • In this section, the hydrodynamics of a dual fluidized beds has been discussed using the almost similar system as described in (Loffler et al. 2003; Kaiser et al., 2003) except the mechanism for the solids transfer between the vessels. Loop seal device has been used in the studies described in (Loffler et al. 2003; Kaiser et al., 2003). In the current study, two L- valves, in place of loop seals, have been installed between the coupled reactors. The L-valves absorb a part of pressure that is built up due to static head of solids in the downcomer. Depending upon the pressure...

  • Stable laws { also called -stable or Levy-stable { are a rich family of probability distributions that allow skewness and heavy tails and have many interesting mathematical properties. They appear in the context of the Generalized Central Limit Theorem which states that the only possible non-trivial limit of normalized sums of independent identically distributed variables is -stable. The Standard Central Limit Theorem states that the limit of normalized sums of independent identically distributed terms with nite variance is Gaussian ( -stable with = 2).
