Towards an Interaction-based Integration of MKM Services into End-User Applications

The Semantic Alliance (SAlly) Framework, first presented at MKM 2012, allows integration of Mathematical Knowledge Management services into typical applications and end-user workflows. From an architecture allowing invasion of spreadsheet programs, it grew into a middle-ware connecting spreadsheet, CAD, text and image processing environments with MKM services. The architecture presented in the original paper proved to be quite resilient as it is still used today with only minor changes. This paper explores extensibility challenges we have encountered in the process of developing new services and maintaining the plugins invading end-user applications. After an analysis of the underlying problems, I present an augmented version of the SAlly architecture that addresses these issues and opens new opportunities for document type agnostic MKM services.Comment: 14 pages, 7 figure

Применение метода контрольных возмущений для определения характерных узлов присоединения комплексной нагрузки при расчетах динамической устойчивости

Рассматривается влияние способа замещения комплексной нагрузки на характер электромеханических переходных процессов в электрических системах (ЭС) от действия больших возмущений. Показано, что установить общие рекомендации относительно способа замещения нагрузки в сложных ЭС затруднительно. Предлагается для опреде­ления характерных узлов нагрузки, оказывающих существенное влияние на характер динамического перехода, применять известный метод контрольных возмущений. Приводятся результаты сравнительных расчетов с использованием предлагаемой методики

Using Games to Create Language Resources: Successes and Limitations of the Approach

Abstract One of the more novel approaches to collaboratively creating language resources in recent years is to use online games to collect and validate data. The most significant challenges collaborative systems face are how to train users with the necessary expertise and how to encourage participation on a scale required to produce high quality data comparable with data produced by “traditional ” experts. In this chapter we provide a brief overview of collaborative creation and the different approaches that have been used to create language resources, before analysing games used for this purpose. We discuss some key issues in using a gaming approach, including task design, player motivation and data quality, and compare the costs of each approach in terms of development, distribution and ongoing administration. In conclusion, we summarise the benefits and limitations of using a gaming approach to resource creation and suggest key considerations for evaluating its utility in different research scenarios

Revision 1 Size and position of the healthy meniscus, and its Correlation with sex, height, weight, and bone area- a cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Meniscus extrusion or hypertrophy may occur in knee osteoarthritis (OA). However, currently no data are available on the position and size of the meniscus in asymptomatic men and women with normal meniscus integrity.</p> <p>Methods</p> <p>Three-dimensional coronal DESSwe MRIs were used to segment and quantitatively measure the size and position of the medial and lateral menisci, and their correlation with sex, height, weight, and tibial plateau area. 102 knees (40 male and 62 female) were drawn from the Osteoarthritis Initiative "non-exposed" reference cohort, including subjects without symptoms, radiographic signs, or risk factors for knee OA. Knees with MRI signs of meniscus lesions were excluded.</p> <p>Results</p> <p>The tibial plateau area was significantly larger (p < 0.001) in male knees than in female ones (+23% medially; +28% laterally), as was total meniscus surface area (p < 0.001, +20% medially; +26% laterally). Ipsi-compartimental tibial plateau area was more strongly correlated with total meniscus surface area in men (r = .72 medially; r = .62 laterally) and women (r = .67; r = .75) than contra-compartimental or total tibial plateau area, body height or weight. The ratio of meniscus versus tibial plateau area was similar between men and women (p = 0.22 medially; p = 0.72 laterally). Tibial coverage by the meniscus was similar between men and women (50% medially; 58% laterally), but "physiological" medial meniscal extrusion was greater in women (1.83 ± 1.06mm) than in men (1.24mm ± 1.18mm; p = 0.011).</p> <p>Conclusions</p> <p>These data suggest that meniscus surface area strongly scales with (ipsilateral) tibial plateau area across both sexes, and that tibial coverage by the meniscus is similar between men and women.</p

Geological and geomorphological features of landslides affecting the area of Cortina d'Ampezzo (Dolomites, Italy)

The paper shows the results of geological and geomorphological investigations recently carried out in the area of Cortina d'Ampezzo (Dolomites, Northern Italy). The study is part of European research projects aiming at the recognition and characterisation of mass movements. The stratigraphical and structural conditions of the study area greatly influenced slope evolution after the retreat of glaciers, favouring the development of large gravitational processes. The geological structure of the area is, in fact, characterised on the one hand by a repeated succession of pelitic rocks and dolomites and on the other hand by the wide presence of pelitic terms (even if largely covered by superficial deposits) in the lower part of the basin. Landslide deposits, which form most of the outcropping Quaternary deposits, have been grouped into "landslide units", in order to make easier the understanding of the complex slope evolution occurred since the Late-glacial period. A "landslide unit" has been defined in this paper as the association of landslide accumulations strictly connected in space and time: it can consist of a single main landslide and successive reactivations or of a superimposition of accumulations caused by repeated activations of a main scarp. The characteristics and distinctive aspects of landslide units are given. Several landslides have been radiocarbon dated. Age and borehole data contributed substantially to the reconstruction of the geomorphological evolution of the area. In particular, they have shown a number of landslides distributed in two main periods. The first ranges between 10,000 and 8,000 years B.P. when, after the retreat of the glaciers, rock walls no longer sustained by the ice masses became prone to landsliding, giving rise to several large-scale mass movements. These consist of rock slides and rock avalanches of considerable size detached from the steep rock walls surrounding Cortina d'Ampezzo. These events have left clear morphological evidence in the landscape, because of their magnitude and the characteristics of the rock masses involved (dolomites). The second period ranges between 5,000 and 4,000 years B.P. when smaller and slower landslides took place generally affecting the pelitic rocks of the lower part of the slopes. The concentration of landslides in this period is likely to be connected to the wetter climatic phase which occurred during the Upper Atlantic which made the slopes more prone to landsliding. At present the area of Cortina d'Ampezzo is still affected by active landslides which, owing to their potential risk for human activities, are monitored by means of automatic surveying systems
