Universal keyboard for mobile learning
Based on analysis of disadvantages of currently used keyboards and methods of keyboard input teaching the requirements to the touch keyboard of a new type are formulated. Free of the deficiencies noted keyboard is proposed, with the changed method of character input. Instead of correlating input characters with certain areas of the screen it is supposed to relate symbols with certain kinds of gestures. This change made it possible to make a universal keyboard, adapted to the national language, suitable for any alphabet and safe from a medical point of view. The additional benefits offered by the keyboard are noteНа основе анализа недостатков используемых в настоящее время клавиатур и методов обучения клавиатурному вводу формулируются требования к сенсорной клавиатуре нового типа. Предлагается клавиатура, свободная от отмеченных недостатков за счет изменения способа ввода символов. Вместо соотнесения вводимых символов с определенными зонами экрана предлагается соотносить символы с определенного вида жестами. Эта замена позволяет сделать клавиатуру универсальной, адаптированной к национальному языку, пригодной для любого алфавита и безопасной с медицинской точки зрения. Отмечаются дополнительные преимущества предлагаемой клавиатур
The main problem of digital educational resources
The assertion is formulated and proved that the main reason for the inadequate use of digital educational resources in schools is the lack of built-in pedagogy. It is shown how pedagogy can be embedded in the resources and what properties they thus acquire. It is explained how to use cognitive digital educational resources in schools to get the most benefit from themФормулируется и доказывается утверждение, что главной причиной незначительного применения электронных образовательных ресурсов в школе является отсутствие встроенной в них педагогики. Показывается, как педагогика может быть встроена в ресурсы, и какие свойства они при этом приобретают. Разъясняется, каким образом следует применять когнитивные электронные учебники и образовательные ресурсы в школе, чтобы получить от них наибольшую польз
FORMATIVE ASSESSMENT: INTENT LOOK

Improving the quality of the industrial enterprise management based on the network-centric approach
The article examines the network-centric approach to the industrial enterprise management to improve the ef ciency and effectiveness in the implementation of production plans and maximize responsiveness to customers. A network-centric management means the decentralized enterprise group management. A group means a set of enterprise divisions, which should solve by joint efforts a certain case that occurs in the production process. The network-centric management involves more delegation of authority to the lower elements of the enterprise’s organizational structure. The industrial enterprise is considered as a large complex system (production system) functioning and controlled amidst various types of uncertainty: information support uncertainty and goal uncertainty or multicriteria uncertainty. The information support uncertainty occurs because the complex system functioning always takes place in the context of incomplete and fuzzy information. Goal uncertainty or multicriteria uncertainty caused by a great number of goalsestablished for the production system. The network-centric management task de nition by the production system is formulated. The authors offer a mathematical model for optimal planning of consumers’ orders production with the participation of the main enterprise divisions. The methods of formalization of various types of uncertainty in production planning tasks are considered on the basis of the application of the fuzzy sets theory. An enterprise command center is offered as an effective tool for making management decisions by divisions. The article demonstrates that decentralized group management methods can improve the ef ciency and effectiveness of the implementation of production plans through the self-organization mechanisms of enterprise divisions.The work has been prepared with the financial support from the Russian Ministry of Education and Science (Contract No. 02.G25.31.0068 of 23.05.2013 as part of the measure to implement Decision of the Russian Government No. 218)
A new approach to the inverse problem for current mapping in thin-film superconductors
A novel mathematical approach has been developed to complete the inversion of
the Biot-Savart law in one- and two-dimensional cases from measurements of the
perpendicular component of the magnetic field using the well-developed
Magneto-Optical Imaging technique. Our approach, especially in the 2D case, is
provided in great detail to allow a straightforward implementation as opposed
to those found in the literature. Our new approach also refines our previous
results for the 1D case [Johansen et al., Phys. Rev. B 54, 16264 (1996)], and
streamlines the method developed by Jooss et al. [Physica C 299, 215 (1998)]
deemed as the most accurate if compared to that of Roth et al. [J. Appl. Phys.
65, 361 (1989)]. We also verify and streamline the iterative technique, which
was developed following Laviano et al. [Supercond. Sci. Technol. 16, 71 (2002)]
to account for in-plane magnetic fields caused by the bending of the applied
magnetic field due to the demagnetising effect. After testing on
magneto-optical images of a high quality YBa2Cu3O7 superconducting thin film,
we show that the procedure employed is effective
