Abstract SRAM bit fail maps (BFM) are routinely collected during earlier phases of yield ramping, providing a rich source of information for IC failure and deformation learning. In this paper, we present an automated approach to analyzing BFM data efficiently. We also demonstrate the usability of our analysis framework using real BFM test data from a large, modern SRAM test vehicle.

Fossil echinoderms are a rich source of information concerning biotic interactions. In this study we analyzed the premortem encrustation of the highly specialized Middle Devonian rugose coralsAspasmophyllum crinophilumand ?“Adradosia” sp. on camerate crinoid stems.Aspasmophylluminfested living crinoid stems by sclerenchymal outgrowth that formed a skeletal ring but ?“Adradosia” sp. encrusted the stems rapidly, without building a ring. These coral-crinoid biocoenoses indicate a settlement advantage for the rugose corals within densely populated communities of the lower Givetian. The corals could be interpreted as large epizoozoans that benefited as secondary tierers reaching relatively high tiering levels. It also suggests the ability for the affected crinoids to repel the coral by overgrowing the corallite with a local increased stereomic growth. Because the crinoid axial canals are not penetrated, the corals cannot be considered as predators or parasites of crinoids. Therefore, the described biocoenosis is interpreted as commensalism. The speciesA. crinophilumis redescribed, and a neotype is defined, because of the loss of the initial types. Two types of ichnofossils can be attributed to the premortem encrustation of both corals. They are described asOstiocavichnusn. ichnogen. and are attributed to the stereomic response of the infested hosts. These swellings are characterized as either elliptical (Ostiocavichnus ovalisn. ichnogen. n. ichnosp. due to the assumed reaction ofA. crinophilum) or subcircular concavities (O. rotundatusn. ichnogen. n. ichnosp. due to the reaction of ?“Adradosiasp.”).

Industrial manufacturing processes often show multiple operating modes, where different modes present different regularities, so real-time monitor and analyzing the quality state stability is an important way to ensure product quality. This paper proposes a state-driven fluctuation space model for quality stability analysis for multimode manufacturing process. First, the whole process is divided into many sub-processes and the multimode formation mechanism is analyzed to form the stability analysis framework. Then each single-mode quality state fluctuation space model is built based on multi-kernel support vector data description method to determine the max effective fluctuation border of the process state. For the current process state, the deep neural network (DNN) is adopted to extract process state features automatically and recognize the mode type. Thus appropriate quality stable fluctuation space model is selected to monitor and analyze the process stability state. Finally, a case study is performed to evaluate the feasibility of proposed stability analysis method, and the result reveals that the method shows good effect for analyzing the process stability in manufacturing process.

Source Of Information

A learner corpus (LC) is widely known as a rich source of information regarding the use of expressions and the errors made by students in their productions. In fact, we, as teachers, can profit from the compilation of their tasks so as to analyze in detail their way of writing. However, the mere compilation of texts does not guarantee a successful exploitation, as more steps than saving texts must be involved in the whole process. Therefore, it seems essential to follow a protocolized methodology of compilation. In this paper we propose five phases for compiling a LC containing texts from the spontaneous written productions from undergraduate and postgraduate students. The outcomes thrown with the LC exploitation will reveal the errors in students’ productions regarding the use of plural, comparative and superlative in adjectives and also other fails detected in the tagging phase, most of which are due to students’ misuses.

John James Audubon's five-volume Ornithological biography (1831–1839), published as the textual companion to The birds of America (1827–1838), remains a rich source of information about North America's avifauna. Issued separately from the prints for both practical and economic reasons, this classic but often forgotten work contained individual biographical accounts of each species shown in the illustrations, based upon the naturalist's decades of field observations. The demands associated with the publication and marketing of the prints compelled Audubon to wait until the end of 1830 before he began to write it, just as the first volume of 100 plates was being completed. Assisted throughout the endeavour by Scottish ornithologist William MacGillivray, who edited Audubon's manuscripts and provided scientific descriptions of each species, the naturalist published the first volume in 1831 in both Edinburgh and Philadelphia, the latter to secure the US copyright. A second Philadelphia edition appeared in 1832. Succeeding volumes were published in Edinburgh in 1834, 1835, 1838, and 1839, following the completion of each of the remaining three volumes of plates. An American edition of the second volume was published in 1835, but almost three-quarters of the copies were destroyed in a Boston fire. With sales of the last three volumes lagging, significantly fewer than 750 complete sets were ever sold.

The pulsations of white dwarf stars are potentially a rich source of information about white dwarf structural properties. Extracting and applying this information to improve our knowledge of white dwarf interiors requires measuring individual eigenperiods in a complex power spectrum, and identifying the character of the eigenmodes they represent. This review will summarize observational progress in these areas for the ZZ Ceti pulsators.

In order to have more accurate analysis about the eruption period of gas eruption under a coal mine system, fractal geometry theory was introduced. Based on field test data, a novel R / S analysis method was used to calculate the Hurst parameter, which determined the persistence correlation of the gas system, and eruption period was calculated subsequently. The period was used by the coal mine factory to arrange the manufacturing process and for three years no accident about gas eruption under the coal mine was reported.

The stories of neonatal care are a rich source of information, going beyond the typical clinical article to convey the meaning of nursing in this special environment. During its run, the Turning Points column in Neonatal Network® gave nurses, doctors, and family members affected by the NICU an outlet to share their stories with others. The brief overview of the columns’ contents provided in this article displays the wide variety of patient cases, workplace issues, and family situations encountered by neonatal nurses.

Abstract Archdeacon Paul of Aleppo of Damascus accompanied the Patriarch Macarios of Antioch, in Moldavia, Wallachia, Dobrogea for nearly seven years (1652-1659), just in time considered one of the coldest during the Little Ice Age, Maunder Minimum namely (1645-1715). His journey is recorded in his travel diary, written in Arabic and translated into Romanian in 1900. Romanian historians were particularly concerned with the information provided by the passenger about the towns, monasteries, and farmhouses, aspects of daily life, customs, habits and Romanian economy countries. But Paul of Aleppo describe and climate issues, particularly cold winters with frost Danube, snowy, storm at sea, rain, floods, etc. It is a very rich source of information in this area, so far little taken into consideration, showing that the Little Ice Age was also evident in Eastern Europe.
