The circular restricted three-body problem is used as an approximate model in space mission planning. Its periodic solutions around equilibrium points, which are referred to as the libration points, are utilized for exploration of possible spacecraft trajectories in the preliminary stages of mission design. In this paper, a numerical methodology for periodic libration point orbits ...

It is not a trivial task to develop an effective overhead power line short circuit sensor while being restricted on weight, dimensions, power consumption, and the relative position of the sensor and the power line wire. Traditionally, a current transformer similar to a Rogowski coil is used as a sensor, followed up by either a ...

The paper consists of three parts. The first one is devoted to approximate methods for evaluating Riemann integrals, singular and hypersingular integrals on closed non-rectifiable curves and fractals in the complex plane. An integral on non-rectifiable curves or fractals is defined as a double integral over a region that bounded by a non-rectifiable curve or ...

An algebraic approach to solving certain nonhomogeneous ODEs is studied. The approach is also extendable to solving certain nonhomogeneous difference equations. The approach is based on representing the right-hand side of the equation as an element of a certain vector space, the restriction of the d/dx operator on which is an automorphism space. ...

Описаны дополнения к стандартным SPICE моделям МОП элементов схем, учитывающие эф-фекты их старения, обусловленные влиянием горячих но-сителей, пробоя диэлектрика и электромиграции. Наборы таких моделей вместе со средствами определения их параметров и средствами SPICE моделирования объ-единены в подсистему SPICE моделирования КМОП схем с учетом факторов старения и оценки параметров надеж-ности и времени бессбойной работы. Приведены примеры ...

The article introduces the theoretical foundations of the modern method of storing, transmitting and processing signals: digital processing. It’s a way to use relatively small number of values instead of continuous real signal.
For example, when transmitting information in telephony, speech is concentrated in the bandwidth up to 4 kHz. But we need doubled frequency 8 ...

A semi-implicit unstructured operator-difference scheme for three-dimensional self-gravitating flows
Kondratyev I., Moiseenko S., Journal of Physics: Conference Series 2021 Vol. 2028 No. 1 Article 012007
A support operators (operator-difference) method has proven itself well for implicit simulations of different astrophysical fluid flows. Following the operator-difference approach, we construct nodal difference analogues of differential operators in Cartesian coordinates, where the conjugacy properties are the same as for original ones. Using the difference operators, we develop an Eulerian semi-implicit gas-dynamical solver with ...

A SPICE macromodel of the SiGe HBTs taking into account aging effects is presented. It consists of the standard core model selected by the designer and an additional subcircuit taking into account the hot-carrier effects. The macromodel was included on SPICE-like simulators. The advantages of SPICE-model version of SiGe HBT are high accuracy of description for device ...

Our paper discusses a novel computational approach to the extended Maximal Covering Location Problem (MCLP). We consider a fuzzy-type formulation of the generic MCLP and develop the necessary theoretical and numerical aspects of the proposed Separation Method (SM). A speciffic structure of the originally given MCLP makes it possible to reduce it to two auxiliary ...
