Influence of the radiation pattern errors for the correlation interferometer

While designing phase-correlation direction finders, as antenna components, the non-directional ones are usually applied. Mounting the non-directional antenna components provides certain new options but makes the bearing computation procedure more problematic. In the present paper, the feasibility of using the directional antenna components is discussed and confirmed in terms of its positive influence on the stability of the bearing results in the case when the deviations of the implementations of the actual diagrams of the antenna components from their reference model occur.

THE IMPACTS OF INDIVIDUAL INFORMATION ON LOSS RESERVING

The projection of outstanding liabilities caused by incurred losses or claims has played a fundamental role in general insurance operations. Loss reserving methods based on individual losses generally perform better than those based on aggregate losses. This study uses a parametric individual information model taking not only individual losses but also individual information such as age, gender, and so on from policies themselves into account. Based on this model, this study proposes a computation procedure for the projection of the outstanding liabilities, discusses the estimation and statistical properties of the unknown parameters, and explores the asymptotic behaviors of the resulting loss reserving as the portfolio size approaching infinity. Most importantly, this study demonstrates the benefits of individual information on loss reserving. Remarkably, the accuracy gained from individual information is much greater than that from considering individual losses. Therefore, it is highly recommended to use individual information in loss reserving in general insurance.

2D Material-based Quantum Logic Gate Operating Via Self-Organization of Quantum Dots

In the paper, nanotrigger-based electronic device, capable of performing the quantum computation procedure, is described. The device represents a quantum logic gate formed from a two-dimensional material and controlled by a quantum dot. The operation of the quantum dot is analyzed. In the model representation, the transition between two states of the quantum dot, each of which controls the flow of the nanotransistor current (one of the shoulders of the nanotrigger), is equivalent to tunneling through an energy barrier separating the states. Fundamentally important is the fact that in one of these states the quantum dot is diamagnetic, and in the other it is paramagnetic. The paramagnetism of the quantum dot is due to the electronic exchange interaction, characteristic of the systems with unpaired electrons. Thus, the elementary self-organized 2D-material-derived logic gate disclosed in the present work can be employed for design of an electronic reversible unit.In other words, such a unit is able to prepare and to trigger the computation procedure.

Analysis of the 2D motion of a monolith platform mechanism

This paper summarises the results of motion analysis of a platform mechanism with a monolith design. A four-link planar mechanism was engineered in which the platform positioning is effected via one passive link and two eccentric links actuated by stepper motors. The prototype of the device was fabricated following a computation procedure based on the classical mechanism and machine theory and FEM calculations. Testing performed on the model and on the real device revealed the presence of two points on the platform for which the resultant of two independent perpendicular displacements implemented by two stages can be obtained for small values of angular displacement.

Map Reduce clustering in Incremental Big Data processing

An advanced Incremental processing technique is planned for data examination in knowledge to have the clustering results inform. Data is continuously arriving by different data generating factors like social network, online shopping, sensors, e-commerce etc. [1]. On account of this Big Data the consequences of data mining applications getting stale and neglected after some time. Cloud knowledge applications regularly perform iterative calculations (e.g., PageRank) on continuously converting datasets. Though going before trainings grow Map-Reduce aimed at productive iterative calculations, it's miles also pricey to carry out a whole new big-ruler Map-Reduce iterative task near well-timed quarter new adjustments to fundamental records sets. Our usage of MapReduce keeps running [4] scheduled a big cluster of product technologies and is incredibly walkable: an ordinary Map-Reduce computation procedure several terabytes of records arranged heaps of technologies. Processor operator locates the machine clean to apply: masses of MapReduce applications, we look at that during many instances, The differences result separate a totally little part of the data set, and the recently iteratively merged nation is very near the recently met state. I2MapReduce clustering adventures this commentary to keep re-calculated by way of beginning after the before affected national [2], and by using acting incremental up-dates on the converging information. The approach facilitates in enhancing the process successively period and decreases the jogging period of stimulating the consequences of big data.

Design of engineering processes for manufacturing and repair of parts with wear-resistant coatings

A computation procedure is developed allowing the definition of inter-operation dimensions and allowances for machining coating applied and also the definition of the route for basic material machining and the substantiation of the parts group formation according to design-technological signs and repair dimensions. In the paper there shown procedures for the computation of coating thickness depending on parts wear. There is developed a circuit to the computation of a coating residual layer. An expression for the computation of coating thickness is obtained. Theoretical dependences and computation procedures are obtained that allows solving the whole problem complex arising at the dimension analysis of engineering processes of manufacturing parts with coatings.
