Path-finding algorithm for the mobile robot

The path-finding algorithm (modified A*) that guaranties the shortest length of trajectory and gives a result with minimum iterations has been developed and realized. The software that implements this routine has been developed. The check of the system has been performed on different samples

MONETARY POLICY UNDER INFLATION TARGETING: AN INTRODUCTION

This brief review takes stock of the recent literature on monetary policy under inflation targeting and introduces new analytical and empirical research in this field. Six key areas of previous research are reviewed: the practice and optimality of inflation targeting regime features; optimal monetary policy; uncertainty, learning, and monetary policy; transparency, communication, and accountability; asset prices and monetary policy; and economic performance under inflation targeting and in comparison to non-targeting regimes. The review suggests a significant number of open issues that are addressed in 13 new contributions presented at the 2005 Annual Conference of the Central Bank of Chile, which are summarized here.

Rectification from Radially-Distorted Scales

This paper introduces the first minimal solvers that jointly estimate lens distortion and affine rectification from repetitions of rigidly transformed coplanar local features. The proposed solvers incorporate lens distortion into the camera model and extend accurate rectification to wide-angle images that contain nearly any type of coplanar repeated content. We demonstrate a principled approach to generating stable minimal solvers by the Grobner basis method, which is accomplished by sampling feasible monomial bases to maximize numerical stability. Synthetic and real-image experiments confirm that the solvers give accurate rectifications from noisy measurements when used in a RANSAC-based estimator. The proposed solvers demonstrate superior robustness to noise compared to the state-of-the-art. The solvers work on scenes without straight lines and, in general, relax the strong assumptions on scene content made by the state-of-the-art. Accurate rectifications on imagery that was taken with narrow focal length to near fish-eye lenses demonstrate the wide applicability of the proposed method. The method is fully automated, and the code is publicly available at https://github.com/prittjam/repeats.Comment: pre-prin

Мобильные роботы: возможности, перспективы, проблемы

Обгрунтована об’єктивна необхідність впровадження мобільних роботів в Україні. Наведено детальний перелік функціональних можливостей мобільних роботів різного призначення. Узагальнена інформація про найбільш досконалі в своїх класах моделі зарубіжних мобільних роботів та про мобільні агрегати, створені в НТУУ «КПІ». Запропонована загальна структура мобільного робототехнічного комплекса, що складається з основної, базової моделі та додаткових, перелічених окремо, спеціалізованих систем та пристроїв. Обгрунтована технічна можливість та економічна доцільність створення та експортування українських конкурентоздатних мобільних роботів. Проведено аналіз головних проблем, що стримують більш широке застосування мобільних роботів та вказані можливі шляхи їх вирішення.This paper contains a detailed list of the functionality of mobile robots in activities of uniformed and emergency services. The works to create and mass produce a number of different classes of mobile robots are widely held in developed countries. The characteristics of these studies are given in the article. This is facilitated by economic benefit of export of mobile robots in developing countries. There are five types of mobile robots which are characterized by high radiation resistance were established in NTU "KPI" for using at the Chernobyl Nuclear Power Plant. The proposed general structure of a typical robotic systems, which is consisting of a basic model and specialized functional systems was listed in the article. The technical possibility and economic feasibility of establishing competitive and export Ukrainian mobile robots were proven. Further development and using of mobile robots constrain two major problems: lack of autonomy and the high cost of them. The reducing the cost of mobile robots can be achieved by the following measures: – to reduce the development costs of certain modifications through the using of model calculations and computer software design; – the unification of the basic structural elements of robots as mobile chassis multilink manipulator, cable drum, etc.; – the comprehensive using of standardized packages of electronic components (f. e. «Micro PC», «PC/104», etc.) in the development of management subsystems work; – to increase in mass production of robots.Обоснована объективная необходимость внедрения мобильных роботов в Украине.

The macroeconomics of a financial Dutch disease

We describe the medium-run macroeconomic effects and long-run development consequences of a financial Dutch disease that may take place in a small developing country with abundant natural resources. The first move is in financial markets. An initial surge in foreign direct investment targeting natural resources sets in motion a perverse cycle between exchange rate appreciation and mounting short- and medium-term capital flows. Such a spiral easily leads to exchange rate volatility, capital reversals, and sharp macroeconomic instability. In the long run, macroeconomic instability and overdependence on natural resource exports dampen the development of nontraditional tradable goods sectors and curtail labor productivity dynamics. We advise the introduction of constraints to short- and medium-term capital flows to tame exchange rate/capital flows boom-and-bust cycles. We support the implementation of a developmentalist monetary policy targeting competitive nominal and real exchange rates in order to encourage product and export diversification

A Multivariate Analysis of United States and Global Real Estate Investment Trusts

Using daily data for the period February 2006 to July 2013 we examine the return and volatility linkages between the two main United States REIT sub-sectors and global linkages between the Americas, Europe and the Asia Pacific regions using the BEKK-GARCH and the DCC-GARCH models. We find that there is no evidence of any volatility spillovers between the US sub-sectors. By contrast, we find evidence of volatility spillovers between the Asia Pacific and the Americas, the Asia Pacific and Europe but no spillovers between the United States and Europe. Our results suggest that the REIT market is becoming increasingly globalized and that investors need to consider time varying volatility and correlations across different regions of the world when forming their optimal portfolio-allocations

Exogenous spatial precuing reliably modulates object processing but not object substitution masking

Object substitution masking (OSM) is used in behavioral and imaging studies to investigate processes associated with the formation of a conscious percept. Reportedly, OSM occurs only when visual attention is diffusely spread over a search display or focused away from the target location. Indeed, the presumed role of spatial attention is central to theoretical accounts of OSM and of visual processing more generally (Di Lollo, Enns, & Rensink, Journal of Experimental Psychology: General 129:481–507, 2000). We report a series of five experiments in which valid spatial precuing is shown to enhance the ability of participants to accurately report a target but, in most cases, without affecting OSM. In only one experiment (Experiment 5) was a significant effect of precuing observed on masking. This is in contrast to the reliable effect shown across all five experiments in which precuing improved overall performance. The results are convergent with recent findings from Argyropoulos, Gellatly, and Pilling (Journal of Experimental Psychology: Human Perception and Performance 39:646–661, 2013), which show that OSM is independent of the number of distractor items in a display. Our results demonstrate that OSM can operate independently of focal attention. Previous claims of the strong interrelationship between OSM and spatial attention are likely to have arisen from ceiling or floor artifacts that restricted measurable performance
