The paper deals with problem analysis due to domestic engineering transition to the Industry 4.0 technology. It presents such innovative technologies as additive manufacturing (3D-printing), Industrial Internet of Things, total digitization of manufacturing (digital description of products and processes, virtual and augmented reality). Among the main highlighted problems the authors include a lack of unification and standardization at this stage of technology development; incompleteness of both domestic and international regulatory framework; shortage of qualified personnel.

Deep Integration

This paper aims to explore Pakistan's geo-economic options in the difficult situation that confronts following the easing of sanctions, which added acute balance of payments pressures to its existing ailments of near-stagnant exports, a lower growth trend than in preceding decades, an unattractive climate for foreign investment, and weak social indicators. The first question explored is whether Pakistan has any opportunity of participating in a regional trade grouping. It is argued that the only conceivable way of achieving this would involve the development of SAARC, which would demand a profound transformation of Indo-Pakistani relations (though one no more profound than that realised in Franco-German relations since the founding of what is now known as the European Union). One benefit of achieving deep integration through SAARC is that this would create the possibility of Pakistan developing a serious engineering industry far more rapidly than will otherwise happen. In the absence of deep integration in SAARC, it is argued that Pakistan's best option would be a policy close to unilateral free trade, so as to place it in a position to take advantage of whatever the next generation of labour-intensive activities demanded by the world economy proves to be. Under either of those scenarios, the reestablishment of a dynamic industrial sector will require the maintenance of a competitive exchange rate, something that, it is argued, is not necessarily guaranteed by floating. The paper also discusses the role of inward direct investment in contributing to the export success of East Asia, and considers whether the expatriate Pakistani community might be capable of playing a role comparable to that played by the overseas Chinese in nurturing the Chinese export expansion of the last two decades. It is suggested that such a hope was set back by the extra-legal attempt to renegotiate power tariffs with the independent power producers in the course of 1998, and that Pakistan needs to become a country of laws rather than discretion if foreign investors, including expatriate Pakistanis, are ever to find the country an attractive export platform. While more inward direct investment would almost certainly be beneficial, the same is not true for inward financial investment, where too large an inflow can easily expose a country to very significant risks, as the East Asian crisis showed. In the long run, Pakistan needs to be prepared to repel excessive capital inflows if they materialise; but its immediate problem is still balance of payments pressure, and this seems to demand targeting a major and sustained improvement in the current account over the next several years.

Uptake Ratio

Metal oxide materials are known for their ability to store thermochemical energy through reversible redox reactions. Metal oxides provide a new category of materials with exceptional performance in terms of thermochemical energy storage, reaction stability and oxygen-exchange and uptake capabilities. However, these characteristics are predicated on the right combination of the metal oxide candidates. In this study, metal oxide materials consisting of pure oxides, like cobalt(II) oxide, manganese(II) oxide, and iron(II, III) oxide (Fe3O4), and mixed oxides, such as (100 wt.% CoO, 100 wt.% Fe3O4, 100 wt.% CoO, 25 wt.% MnO + 75 wt.% CoO, 75 wt.% MnO + 25 wt.% CoO) and 50 wt.% MnO + 50.wt.% CoO), which was subjected to a two-cycle redox reaction, was proposed. The various mixtures of metal oxide catalysts proposed were investigated through the thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), energy dispersive X-ray (EDS), and scanning electron microscopy (SEM) analyses. The effect of argon (Ar) and oxygen (O2) at different gas flow rates (20, 30, and 50 mL/min) and temperature at thermal charging step and thermal discharging step (30–1400 °C) during the redox reaction were investigated. It was revealed that on the overall, 50 wt.% MnO + 50 wt.% CoO oxide had the most stable thermal stability and oxygen exchange to uptake ratio (0.83 and 0.99 at first and second redox reaction cycles, respectively). In addition, 30 mL/min Ar–20 mL/min O2 gas flow rate further increased the proposed (Fe,Co,Mn)Ox mixed oxide catalyst’s cyclic stability and oxygen uptake ratio. SEM revealed that the proposed (Fe,Co,Mn)Ox material had a smooth surface and consisted of polygonal-shaped structures. Thus, the proposed metallic oxide material can effectively be utilized for high-density thermochemical energy storage purposes. This study is of relevance to the power engineering industry and academia.

The Times

Artificial intelligence technology has been widely used in all aspects of our life. Similarly, the application of artificial intelligence in the field of construction engineering is a necessary trend in the development of engineering industry, especially in the traditional construction engineering department. Under the background of the times, from the perspective of knowledge, artificial intelligence technology has appeared a huge development, which may have an impact on the employment of Chinese labor force, may create new jobs, or replace traditional jobs. This effect on employment is essential. From the perspective of machine learning and artificial intelligence, this paper reviews the transformation prospects of engineering industry and the development of agricultural industry in construction industry, and examines the intellectual transformation of individual human capital in Chinese labor force.

This article discusses the issue of hardened steel machining. Many components in the engineering industry use hardening as the final heat treatment. These components usually occupy a significant position in a given assembly unit. They guarantee the correct operation of the entire technical equipment in total cooperation with other components. The quality of these components depends on the integrity of their surface. The production of these parts is usually carried out by traditional technological procedures. Clearly, an example of such a technology is grinding. However, this article discusses the application of other finishing technologies using a tool material made of cubic boron nitride (CBN). The technology used is finishing turning with subsequent tumbling technology. The subject of the evaluation is the integrity of the surface. In this part of the experiments, there are mainly individual parameters of surface roughness. Compared components are bearing rings, in this case the inner surface of the housing ring.
