Giving a Sense: A Pilot Study in Concept Annotation from Multiple Resources

We present a pilot study of a web-based annotation of words with senses. The annotated senses come from several knowledge bases and sense inventories. The study is the first step in a planned larger annotation of grounding and should allow us to select a subset of the sense sources that cover any given text reasonably well and show an acceptable level of inter-annotator agreement

TectoMT – a deep-­linguistic core of the combined Chimera MT system

Chimera is a machine translation system that combines the TectoMT deep-linguistic core with phrase-based MT system Moses. For English–Czech pair it also uses the Depfix post-correction system. All the components run on Unix/Linux platform and are open source (available from Perl repository CPAN and the LINDAT/CLARIN repository). The main website is https://ufal.mff.cuni.cz/tectomt. The development is currently supported by the QTLeap 7th FP project (http://qtleap.eu)

Dictionary-based Domain Adaptation of MT Systems without Retraining

We describe our submission to the IT-domain translation task of WMT 2016. We perform domain adaptation with dictionary data on already trained MT systems with no further retraining. We apply our approach to two conceptually different systems developed within the QTLeap project: TectoMT and Moses, as well as Chimera, their combination. In all settings, our method improves the translation quality. Moreover, the basic variant of our approach is applicable to any MT system, including a black-box one

FEASIBILITY OF TYPE OF DEEP-WATER TECHNOLOGIES FOR THE EXTRACTION OF MARINE FERRO-MANGANESE NODULES

The conditions for the occurrence of near bottom minerals presented in the form of sulphides (the Logachev deposit) and ferro-manganese nodules (The conditions for the occurrence of benthic minerals presented in the form of sulphides (the Logachev deposit) and ferro-manganese nodules (FMN) are considered. An analysis of the structures and parameters of various means of collecting and transporting sulphides and iron ore from the bottom to the surface is given, and the possibility of effectively using vessel lifting on a cable-rope is indicated. Structural schemes for collecting FMN and sulphides in the form of containers on a cable, equipped with manipulators with gripping devices of a disc, drum or clamshell type, are proposed. In them, the capture of rock pieces or FMN is carried out by creating a vacuum in the collectors of the executive bodies and attracting to them pieces of rock or FMN by a pressure drop of water inside and outside the reservoir. It was given the approximate parameters of the mining system. So, for a cable-rope made of kevlar with a diameter of 50 mm, the capacity can be 200-400 thousand tons per year for one installation with different specific mass concentration of FMN per 1 m2) are considered

Modern Mathematical Forecast Methods of Maintenance and Support Conditions for Mining Tunnel

The research focuses on mathematical methods of mining pressure forecast to develop rational support patterns for mining tunnels and to ensure safety of mining operations. The purpose of research is to develop the methodology of applying advanced calculation methods and software solutions based on neural networks to reduce dispersion of factors influencing stability of mining tunnels, as well as to define rational parameters of mining tunnel support. The authors review the algorithm of geomechanical process examination, which is divided into several stages. First of all, it is proposed to use cluster analysis to examine location conditions of man-made outcrops, which allows to divide all the diversity of existing conditions for mining tunnel construction. Cluster analysis first allows to reduce the dispersion of factors that influence the stability of mining tunnels in various clusters, and then to determine rational parameters of tunnel support in each cluster. After the problem of cluster analysis is solved, it is proposed to use software programs that allow to study geomechanical processes in each cluster. At this stage, both standard methods (normative techniques, numerical modelling, analogies use, etc.) and the most advanced methods – neural networks – can be applied. Described algorithm of solving geomechanical problems, which utilizes advanced numerical methods and a software package based on neural networks, ensures an individual approach to estimation of mining pressure under varying conditions of man-made outcrop location in the rock mass

Влияние фрикционной перемешивающей обработки на микроструктуру и механические характеристики латуни марки Л63

В работе производилось исследование микроструктуры и механических свойств латуни марки Л63 после фрикционной перемешивающей обработки. Показано, что с увеличением количества проходов инструмента, размер зерна в зоне перемешивания уменьшаются за счет высоких пластических деформаций, что приводит к образованию мелкозернистой структуры. Микротвердость сплава Л63 в зоне перемешивания увеличивается на величину до 30% по сравнению с основным металлом. Предел прочности не существенно зависит от количества проходов инструментом вдоль линии обработки, в то время как предел текучести увеличивается на величину до 29%

Роль молекулярно-генетических методов определения Т-и В-клеточной клональности в диагностике злокачественныхлимфом кожи

The article presents the data on the studies contributing to improving the differential diagnostics of T-cell and B-cell cutaneous lymphomas including large-plaque parapsoriasis and T-cell and B-cell cutaneous pseudolymphomas as well as frequency of their transformation into malignant cutaneous lymphomas. There was a study of 101 patients using the polymerase chain reaction method to determine the T-cell and B-cell lymphocyte clonality by genes of g and chains in the T-cell receptor and immunoglobulin heavy chain genes. Monoclonality was determined in 40 of 46 cases in patients with T-cell cutaneous lymphomas and in three of four cases in patients with B-cell cutaneous lymphomas. Monoclonality was revealed in one of 14 cases of large-plaque parapsoriasis and one of two cases of T-cell cutaneous pseudolymphoma. In all of the 24 cases of chronic benign dermatoses, five cases of small-plaque parapsoriasis and ten skin tissue samples obtained from healthy donors, polyclonal lymphocytes were revealed. So, the obtained results make it possible to consider the method to be an important addition in the field of diagnosing lymphoproliferative skin diseases.Приведены данные об исследованиях, способствующих совершенствованию дифференциальной диагностики Т- и В-клеточных лимфом кожи, в том числе с крупнобляшечным парапсориазом, Т- и В-клеточными псевдолимфомами кожи, а также о частоте их трансформации в злокачественные лимфомы кожи. У 101 пациента проведено обследование методом полимеразной цепной реакции с целью определения Т- и В-клеточной клональности лимфоцитов по генам g- и -цепей Т-клеточного рецептора и генам тяжелой цепи иммуноглобулина. У пациентов с Т-клеточными лимфомами кожи моноклональность определялась в 40 из 46 случаев, с В-клеточными лимфомами кожи - в 3 из 4 случаев. Также моноклональность была выявлена в 1 из 14 случаев крупнобляшечного парапсориазам и в 1 из 2 случаев Т-клеточной псевдолимфомы кожи. Во всех 24 случаях хронических доброкачественных дерматозов, 5 случаях мелкобляшечного парапсориаза и 10 биоптатах кожи от здоровых доноров была выявлена поликлональность лимфоцитов. Таким образом, полученные результаты позволяют считать данный метод важным дополнением в диагностике лимфопролиферативных заболеваний кожи

On the possibility of reducing man-made burden on benthic biotic communities when mining solid minerals using technical means of various designs

The paper analyses features of the species composition and diversity of biotic communities living within the ferromanganese nodule fields (the Clarion-Clipperton field), cobalt-manganese crusts (the Magellan Seamounts) and deep-sea polymetallic sulphides (the Ashadze-1, Ashadze-2, Logatchev and Krasnov fields) in the Russian exploration areas of the Pacific and Atlantic Oceans. Prospects of mining solid minerals of the world’s oceans with the least possible damage to the marine ecosystems are considered that cover formation of the sediment plumes and roiling of significant volumes of water as a result of collecting the minerals as well as conservation of the hydrothermal fauna and microbiota, including in the impact zone of high temperature hydrothermal vents. Different concepts and layout options for deep-water mining complexes (the Indian and Japanese concepts as well as those of the Nautilus Minerals and Saint Petersburg Mining University) are examined with respect to their operational efficiency. The main types of mechanisms that are part of the complexes are identified and assessed based on the defined priorities that include the ecological aspect, i.e. the impact on the seabed environment; manufacturing and operating costs; and specific energy consumption, i.e. the technical and economic indicators. The presented morphological analysis gave grounds to justify the layout of a deep-sea minerals collecting unit, i.e. a device with suction chambers and a grip arm walking gear, selected based on the environmental key priority. Pilot experimental studies of physical and mechanical properties of cobalt-manganese crust samples were performed through application of bilateral axial force using spherical balls (indenters) and producing a rock strength passport to assess further results of the experimental studies. Experimental destructive tests of the cobalt-manganese crust by impact and cutting were carried out to determine the impact load and axial cutting force required for implementation of the collecting system that uses a clamshell-type effector with a built-in impactor
