  • The following report was prepared immediately after the writer's return from the conference. It was written from the viewpoint of an engineer listening to experts in a field far separated from his own. Such judgments as may be found interspersed amongst the reports of individual papers are of an engineering nature, and are not to be construed, as being based upon other than an amateur’s knowledge of linguistic theory.

  • This paper presents an experimental preference tool des!gned, implemented and tested m the Eurotra pro)ect. The mechanism is based on preference rules which can either compare subtrees pairwise or single out a subtree on the basis of some specified constraints. Scoring permits combining the effects of various preference rules.

  • The third book of four-volume edition of “Solar Cells” is devoted to solar cells based on silicon wafers, i.e., the main material used in today's photovoltaics. Single-crystalline Si (c-Si) modules are among the most efficient but at the same time the most expensive since they require the highest purity silicon and involve a lot of stages of complicated processes in their manufacture. Polycrystalline silicon (mc-Si) cells are less expensive to produce solar cells but are less efficient.

  • One of the most fundamental question that an Engineer has to ask him/herself is what is how does it deform, and when does it break. Ultimately, it its the answer to those two questions which would provide us with not only a proper safety assesment of a structure, but also how to properly design it. Ironically, botht he ACI and the AISC codes are based on limit state design, yet practically all design analyses are linear and elastic.

  • For writers of technical books, there can be no better piece of advice. Around the time of writing the first edition – about a decade ago – there were very few monographs on this subject: today, there are possibly no less than 20. Based on critical inputs, this edition stands thoroughly revamped. New chapters on ventilator waveforms, airway humidification, and aerosol therapy in the ICU now find a place. Novel software-based modes of ventilation have been included. Ventilator-associated pneumonia has been separated into a new chapter.

  • In the latest years graphene based research has witnessed a tremendous explosion. This two dimensional ‘‘dream’’ material has come into the main spotlight of fundamental and applied research in diverse nano-science fields, but surprisingly rapidly, it has also attracted the interest of major stakeholders in the private sector.

  • Private real estate investment is a typical one-shot decision problem for personal investors due to the huge investment expense and the fear of substantial loss. There is only one outcome for a one-shot decision problem. The private real estate investment problem is analyzed within a one-shot decision framework. The procedure for a one-shot decision consists of two steps. In the first step, for each alternative, some states of nature, which are called focus points, are selected amongst all states of nature based on the attitudes of decision makers on uncertainty.

  • There are two general decision making strategies that judges use when evaluating a beer. In a top-down decision making strategy, the judge forms an overall impression about the quality of the beer, decides what overall score to assign that beer, and deducts points for each deficient characteristic of the beer based on the overall impression. The problem with this top-down approach to beer evaluation is that it is difficult to ensure that the points allocated to each subcategory (e.g.

  • HAVING STARTED WORK on mechanical translation, we arrived at the conclusion that both the lexical meaning and the morphological shape of the word can and should be utilized in analyzing the text, and that for purposes of translation it is impractical to omit the information which can be thus obtained. The utilization of the lexical meanings of words as well as of their contexts may also affect problems of coding. These questions are extremely important to automatic translation. We based our work on the following principles: 1.

  • Identifying background (context) information in scientific articles can help scholars understand major contributions in their research area more easily. In this paper, we propose a general framework based on probabilistic inference to extract such context information from scientific papers. We model the sentences in an article and their lexical similarities as a Markov Random Field tuned to detect the patterns that context data create, and employ a Belief Propagation mechanism to detect likely context sentences. ...

  • We present an efficient procedure for cost-based abduction, which is based on the idea of using chart parsers as proof procedures. We discuss in detail three features of our algorithm - - goal-driven bottom-up derivation, tabulation of the partial results, and agenda control mechanism - - and report the results of the preliminary experiments, which show how these features improve the computational efficiency of cost-based abduction.

  • 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 is dealing with formulation of photodegradable films based on polyethylenecassava starch blend using benzophenone/antraquinone or Fe(II) compound as photosensitive compound. Benzophenone, antraquinone and Fe(II) compound were synthesized in the laboratory and characterized by IR and NMR spectra. The films were obtained by extrusion-blowing method and showed good mechanical properties. They were exposed outdoor and indoor for photodegradability testing. It showed that after four months outdoor their tensile at break decreased 85% and elongation at break about 90%.

  • Relation extraction is the task of finding semantic relations between two entities from text. In this paper, we propose a novel feature-based Chinese relation extraction approach that explicitly defines and explores nine positional structures between two entities. We also suggest some correction and inference mechanisms based on relation hierarchy and co-reference information etc. The approach is effective when evaluated on the ACE 2005 Chinese data set.

  • This paper proposes a principled approach for analysis of semantic relations between constituents in compound nouns based on lexical semantic structure. One of the difficulties of compound noun analysis is that the mechanisms governing the decision system of semantic relations and the representation method of semantic relations associated with lexical and contextual meaning are not obvious.
