Problems in simultaneous graph drawing involve the layout of several graphs on a shared vertex set. This paper describes a Graph Simultaneous Embedding Tool, GraphSET, designed to allow the investigation of a wide range of embedding problems. GraphSET can be used in the study of several variants of simultaneous embedding including simultaneous geometric embedding, simultaneous embedding with fi...

Some e-shops present product attributes in structured form, but many others use the textual description only. Attributes of products are essential in automated product deduplication. We suggest methods for automated extraction of attributes and their values from product descriptions to a structural form. The structural data extracted from other e-shops are used as background knowledge.

We study the simultaneous embeddability of a pair of partitions of the same underlying set into disjoint blocks. Each element of the set is mapped to a point in the plane and each block of either of the two partitions is mapped to a region that contains exactly those points that belong to the elements in the block and that is bounded by a simple closed curve. We establish three main classes of ...

This note is a resume of Jerry Hausman’s Nake course at the NAKE workshop in Den Haag, The Netherlands in June 2002. It presents an intuitive framework in which the impact of weak/invalid instruments on properties of di¤erent estimators can be analyzed while also suggesting a test to detect the presence of weak/invalid instruments.

a close study of the conduct of a translator or an interpreter indicates that there are a large number of factors which can play a significant role in their success or failure in their profession. the present paper is intended to probe into a number of these factors which appear to have a rather more important role in the profession of interpreters. it is accepted though, by the majority of the...

in the recent years, renewable energy sources are an important component of world energy consumption. gdp is one of the main measures of a country’s economic activity. most of the studies examine the impact of renewable energy consumption on gdp with single equation model and the others use dynamic panel data. since the granger causality analysis’s findings of this paper establish bidirectional...

objective(s): the energy resolution of a cadmium-zinc-telluride (czt) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional anger type detector which is 10%. also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. in this study, we used a semiconductor detector and examined the ef...

rapid and accurate identification of microorganisms have a significant impact on strategies and fish health management programs. hence, in this study a duplex pcr assay based on the 16s rrna gene for simultaneous detection of aeromonas hydrophila rticc 1032 and escherichia coli rticc 2325 from pure cultures, and challenged fish tissues was performed and their results were compared with the resu...

abstract scaling methods, which are based on similar media theory, are used to simplify the statistic description of soil spatial variations. to simulate the water flow in heterogeneous soils, simultaneous scaling of soil hydraulic functions, including soil water retention and unsaturated hydraulic conductivity functions, is highly desirable. in the similar media theory, the simultaneous scalin...

abstract the aim of this research was to investigate the enthalpy variations of iranian flat breads during storage in room temperature and determining relationship between enthalpy and amount of staling development. for this purpose, the major iranian breads including barbari, taftoon, lavash and sangak beside baguette, were prepared using standard ingredients, specific recipe, and under contro...
