Extreme View

The secular poetry of Philippe Desportes (1546-1606) is most often characterized as précieux. One may wish to distinguish between préciosité as an historical phenomenon and précieux as a recurring literary tendency, and one may quarrel about the exact definition of the term, but when examples are needed none are any better than those chosen from the works of Desportes. This no one would deny, but when the extreme view is taken that Desportes is nothing but an insincere and clever versifier who crassly imitates Italian models and hawks his wares to the highest bidder, then one must protest.

The stock market is an essential sub-sector in the financial area. Both understanding and evaluating the mountains of collected stock data has become a challenge in relevant fields. Data visualisation techniques can offer a practical and engaging method to show the processed data in a meaningful way, with centrality measurements representing the significant variables in a network, through exploring the aspects of the exact definition of the metric. Here, in this study, we conducted an approach that combines data processing, graph visualisation and social network analysis methods, to develop deeper insights of complex stock data, with the ultimate aim of drawing the correct conclusions with the finalised graph models. We addressed the performance of centrality metrics methods such as betweenness, closeness, eigenvector, PageRank and weighted degree measurements, drawing comparisons between the experiments’ results and the actual top 300 shares in the Australian Stock Market. The outcomes showed consistent results. Although, in our experiments, the results of the top 300 stocks from those five centrality measurements’ rankings did not match the top 300 shares given by the ASX (Australian Securities Exchange) entirely, in which the weighted degree and PageRank metrics performed better than other three measurements such as betweenness, closeness and eigenvector. Potential reasons may include that we did not take into account the factor of stock’s market capitalisation in the methodology. This study only considers the stock price’s changing rates among every two shares and provides a relevant static pattern at this stage. Further research will include looking at cycles and symmetry in the stock market over chosen trading days, and these may assist stakeholder in grasping deep insights of those stocks.

The term ultimate resolution or resolving power is the very best performance that can be obtained from a scanning electron microscope (SEM) given the optimum instrumental conditions and sample. However, as it relates to SEM users, the conventional definitions of this figure are ambiguous. The numbers quoted for the resolution of an instrument are not only theoretically derived, but are also verified through the direct measurement of images on micrographs. However, the samples commonly used for this purpose are specifically optimized for the measurement of instrument resolution and are most often not typical of the sample used in practical applications.SEM RESOLUTION. Some instruments resolve better than others either due to engineering design or other reasons. There is no definitively accurate definition of how to quantify instrument resolution and its measurement in the SEM.

This paper is the second part of a two-part paper which introduces a general schema theory for genetic programming (GP) with subtree-swapping crossover (Part I (Poli and McPhee, 2003)). Like other recent GP schema theory results, the theory gives an exact formulation (rather than a lower bound) for the expected number of instances of a schema at the next generation. The theory is based on a Cartesian node reference system, introduced in Part I, and on the notion of a variable-arity hyperschema, introduced here, which generalises previous definitions of a schema. The theory includes two main theorems describing the propagation of GP schemata: a microscopic and a macroscopic schema theorem. The microscopic version is applicable to crossover operators which replace a subtree in one parent with a subtree from the other parent to produce the offspring. Therefore, this theorem is applicable to Koza's GP crossover with and without uniform selection of the crossover points, as well as one-point crossover, size-fair crossover, strongly-typed GP crossover, context-preserving crossover and many others. The macroscopic version is applicable to crossover operators in which the probability of selecting any two crossover points in the parents depends only on the parents' size and shape. In the paper we provide examples, we show how the theory can be specialised to specific crossover operators and we illustrate how it can be used to derive other general results. These include an exact definition of effective fitness and a size-evolution equation for GP with subtree-swapping crossover.

Abstract. We have designed an orthogonal curvilinear terrain-following coordinate (the orthogonal σ coordinate, or the OS coordinate) to reduce the advection errors in the classic σ coordinate. First, we rotate the basis vectors of the z coordinate in a specific way in order to obtain the orthogonal, terrain-following basis vectors of the OS coordinate, and then add a rotation parameter b to each rotation angle to create the smoother vertical levels of the OS coordinate with increasing height. Second, we solve the corresponding definition of each OS coordinate through its basis vectors; and then solve the 3-D coordinate surfaces of the OS coordinate numerically, therefore the computational grids created by the OS coordinate are not exactly orthogonal and its orthogonality is dependent on the accuracy of a numerical method. Third, through choosing a proper b, we can significantly smooth the vertical levels of the OS coordinate over a steep terrain, and, more importantly, we can create the orthogonal, terrain-following computational grids in the vertical through the orthogonal basis vectors of the OS coordinate, which can reduce the advection errors better than the corresponding hybrid σ coordinate. However, the convergence of the grid lines in the OS coordinate over orography restricts the time step and increases the numerical errors. We demonstrate the advantages and the drawbacks of the OS coordinate relative to the hybrid σ coordinate using two sets of 2-D linear advection experiments.

Since the emergence of digital hydraulic technology, it has achieved good results in intelligence, integration, energy saving, etc. After decades of development, and it has also attracted wide attention in the industry. However, for many years, the definition of digital hydraulic technology has differed between researchers, and there is no uniform definition. Such a situation affects the development of it to a certain extent. Therefore, this paper gives the exact definition of digital hydraulic technology based on a large number of researches on it. At the same time, the paper analyzes the research status and developmental process of the such a technology, and we forecast the development trend of it.

Consumers in Croatia only recently got the opportunity to buy exotic fruits and vegetables. Until now offer was limited to the already known species which could be found on the shelves for decades, and this types can generally be cultivated in Croatia (except bananas, pineapples and several types of citrus). The demand for exotic fruits and vegetables and its cultivation in Western Europe is growing, and this trend is coming to Croatia. In the study conducted for the city of Zadar the correlation of the interest in buying exotic fruit/vegetables and familiarity with the product, the exact definition of the product and the most significant characteristics of kiwano/sweet potatoes was explored. Regression analysis results showed that all three independent variables significantly predict purchase of both kiwano and sweet potatoes. Three segments of consumers with respect to their demographic characteristics were identified using cluster analysis. A more detailed analysis of these groups could serve future researchers in order to segment the market and determine the marketing approach to each of the segments.

The aim of this article is to fill the informative gap and to overcome those difficulties which arise in case of not having the adequate interpetation or exact definition of the English idioms in the Georgian dictionaries.This paper investigates some idiomatic expressions and observes how often they are used in the modern English publicist texts from “The Guardian”, “Fortune”, “The Scotsman”, “The Independent” etc. whether they have preserved their original meanings or obtained some other new senses and coloring. More than this, the goal is to research if there is an adequate translation or interpretation of those English idioms in the Georgian language bilingual dictionaries. If there is not any, then the objective is how to make their adequate Georgian equivalents and, as a result to compose a new mini-dictionary of idioms. The urgent need for etymological study of idioms is also stimulated by the fact that the phraseology condensates the complex interaction of the culture and psychology of people, national self-being and their unique metaphoric mentality The reaserch value is dectated by its outcome, namely, it will be the research not only of those idioms which have the adequate definitions in the Georgian dictionaries, but find out some cases of not having the right definition and in result to compile the mini be-lingual dictionary of idioms. It can be assumed, that it will make a siginificant contribution to the development of lexicography in Georgia.
