The Economic Competition Between the USSR and the USA in the Field of Machine-Tool Manufacture

The purpose of this paper is to detail the extent of computer activity in mainland China: hardware, software and endues, and to examine the ramifications such activity has with respect to the USA. Much of the information is based on the authors findings during a recent mission to China. The message is that China possesses a burgeoning computer industry, but one which is at our own 1965 level. The ten years of Cultural Revolution anarchy are responsible for this backwardness. However, Deng Xiaoping, Chinas present leader, is determined that China will take its place with industrialized nations. This means increased opportunity for the US computer industry and the prospect of economic competition in the computer arena.

Belt And Road

This article intends to look at how contemporary and future Asian connectivity linkages are likely to impact Asian geopolitics and geo-strategy. While China has dominated the contemporary connectivity discourse with its Belt and Road Initiative (BRI), other players such as Australia, India, Japan and the USA are engaged in their own connectivity bids which often converge and intersect in the region. As a result, the countries involved in the Indo-Pacific cross-linkages are tacitly entering a game of one-upmanship. Influence through connectivity linkages has also shifted the discourse around balance of power for countries to balance of influence. It is in this context that initiatives such as the Mausam find centrality in the country’s changing outlook. This article attempts to look at Asian connectivity from a dual perspective of economic competition, on one hand, and strategic calculations, on the other hand. The scope of the article is limited to analysing China, India and Japan as leading Asian countries in the emerging connectivity competition, besides the USA as the most important external players in Asian connectivity geopolitics and geo-strategy.

Intensity Of Competition

In this paper the increasing intensity of intermunicipal and interstate economic competition in the USA is noted. It is argued that the federal structure of the USA, the present political climate, and the mobility of capital combine to produce a situation of positive feedback leading to everincreasing subsidies. The situation constitutes a classic prisoner's dilemma. Decreased competition would be in the interests of all units of government. However, there is no way that a state or local government can opt out of the competition unilaterally and no mechanism by which collective action can be taken to reduce the intensity of competition. Also considered in this paper are the aggregate effects of local economic development programs in terms of taxes and public expenditures, efficiency, and equity, and several less commonly discussed considerations.

Tool Manufacture

Thermal error is one of the main sources of machining error of machine tools. Being a key component of the machine tool, the spindle will generate a lot of heat in the machining process and thereby result in a thermal error of itself. Real-time measurement of thermal error will interrupt the machining process. Therefore, this paper presents a machine learning model to estimate the thermal error of the spindle from its feature temperature points. The authors adopt random forests and Gaussian process regression to model the thermal error of the spindle and Pearson correlation coefficients to select the feature temperature points. The result shows that random forests collocating with Pearson correlation coefficients is an efficient and accurate method for the thermal error modeling of the spindle. Its accuracy reaches to 90.49% based on only four feature temperature points—two points at the bearings and two points at the inner housing—and the spindle speed. If the accuracy requirement is not very onerous, one can select just the temperature points of the bearings, because the installation of temperature sensors at these positions is acceptable for the spindle or machine tool manufacture, while the other positions may interfere with the cooling pipeline of the spindle.
