Design of locally cooled step-less fan for industrial use using Arduino programming

Under the background of the development of domestic and foreign manufacturing industries and the increasing demand for industrial products at home and abroad, and under the premise of ensuring and even further reducing the manufacturing cost of manufacturers, how to effectively detect and cool the local temperature of industrial parts is a problem worth studying. After analyzing the advantages and disadvantages of traditional manual control and gear adjustment to adjust the fan, the design will be programmed using Arduino. The fan combines infrared sensor technology to detect the presence and position of parts. A temperature sensor is also set up to detect local temperatures in real-time. A fan with automatic step-less speed change according to temperature is obtained. This fan is used for heat dissipation control of local parts in industrial production, thereby reducing the cost of manual control. It further improves control accuracy and efficiency, improves product quality, and ensures production safety.

An optimized stator and rotor design of squirrel cage induction motor for EMU train

This paper aims to objectively calculate the 480-kW squirrel cage induction motor (SCIM) design for the electric multiple unit (EMU) trains. This is done by optimizing the stator slot and rotor slot design to get efficiency and power factor targets. The stator slot design is achieved by limiting the width and height of the stator slot pitch according to the specified range. A depth-to-width ratio is used according to the range to optimize the design of the rotor bar slot. The design process of the induction motor consists of three steps: it determines the specification design target, calculates the specified parameters of the induction motor, and simulates the design to obtain the most optimal motor design using ANSYS Maxwell. The simulation performance values obtained an efficiency of 92.547 % and a power factor of 0.915. This value is obtained from the optimization of the rotor slot and has met the minimum requirements of efficiency and power factor in designing a SCIM. The design proposed in this paper can be developed and applied in the Indonesian domestic railway manufacturing industry.

Design and Implementation of OPC UA-Based VR/AR Collaboration Model Using CPS Server for VR Engineering Process

In order to cope with the changing era of the innovative management paradigm of the manufacturing industry, it is necessary to advance the construction of smart factories in the domestic manufacturing industry, and in particular, the 3D design and manufacturing content sector is highly growthable. In particular, the core technologies that enable digital transformation VR (Virtual Reality)/AR (Augmented Reality) technologies have developed rapidly in recent years, but have not yet achieved any particular results in industrial engineering. In the manufacturing industry, digital threads and collaboration systems are needed to reduce design costs that change over and over again due to the inability to respond to various problems and demands that should be considered when designing products. To this end, we propose a VR/AR collaboration model that increases efficiency of manufacturing environments such as inspection and maintenance as well as design simultaneously with participants through 3D rendering virtualization of facilities or robot 3D designs in VR/AR. We implemented converting programs and middleware CPS (Cyber Physical System) servers that convert to BOM (Bill of Material)-based 3D graphics models and CPS models to test the accuracy of data and optimization of 3D modeling and study their performance through robotic arms in real factories.

Urban-economic geographies beyond production: Nairobi’s sociotechnical system and the challenge of generative urbanization

AbstractUrban-regional economies are developing in highly variegated, uneven ways globally. In economic geography, studies of urban-regional development emphasize the prospects for innovative, globally-competitive industrial sectors to emerge and enhance a city-region’s exchange value in global markets. This focus reflects a productivist bias that may fail to address issues related to the use-value of, or living conditions associated with urban transitions. Such concerns are particularly significant in the Global South where urbanization has often not led to socioeconomic transformations that benefit the majority of urban residents. To examine the relationships between a city’s exchange and use value, this paper argues for a sociotechnical systems approach that conceptualizes cities as constituted by interdependent or coupled regimes related to production, consumption, and infrastructure that stabilize urban-regional economies and determine development pathways. The framework is deployed empirically to examine the case of Nairobi, Kenya – a rapidly growing urban-regional economy characterized by high rates of inward foreign direct investment, principally in speculative real estate ventures in the consumption regime. Domestic manufacturing industries (the production regime) are stagnating, struggling to compete against imports, and failing to generate widespread formal employment and raise tax revenues for the infrastructure regime. The net result is a city characterized by fragmented or splintered regimes that create highly uneven, exclusionary development outcomes. These dynamics and findings are analyzed in relation to a similar study of Dar es Salaam, Tanzania in order to demonstrate the comparative potential of this conceptual approach. The paper concludes with a call for economic geographers to better account for the use-value of urban-regional economies such that development concerns beyond production become more central to our analyses.

Second-Hand-Clothing Imports in Least-Developed-Countries: The Collapse of Local Clothing Manufacturing and Remedial Measures

Considering the overwhelming global trend of second-hand clothing trade, domestic clothing manufacturing industries in many least developed countries (LDCs) have collapsed. Governments of many LDCs, therefore, have imposed tariff policies on the imports of second-hand clothing. Motivated by the real-world practices, we develop a two-stage Stackelberg supply chain gaming model to study the competition between the locally manufactured new clothing product and the imported second-hand clothing product. We first explore whether import tariff protection can help boost domestic clothing manufacturing industries in LDCs in the light of risk considerations and what the optimal import tariff structure is. We find that in the uncertain LDC market, imposing a high import tariff or a high value-added tax (VAT) on the imported second-hand product may not help local manufacturing. Instead, implementing a carrot-and-sticks (CaS) scheme, which includes an import tariff, a VAT, and an extra incentive, can help. The LDC governments are suggested to adjust the CaS scheme's structure based on factors like risk attitudes of supply chain members, the unit product supply costs, social health risk, and consumer acceptance level of the second-hand product. Finally, we extend our analyses to study the social welfare and the extended importer responsibility (EIR) legislation. We find that if the sterilization cost of the second-hand product is sufficiently low, imposing the EIR legislation in the uncertain LDC market is not beneficial to the domestic clothing manufacturing industry. Specific conditions under which imposing a higher import tariff is beneficial or harmful to the LDC society are identified.

기혼 여성근로자들의 프로틴 경력지향성과 일-가정 균형 및 경력만족의 관계 - 업무 후 모바일기기 사용의 조절된 매개효과를 중심으로 -

In this study, the controlled mediating effects of work-family balance and mobile device use after work were verified in order to investigate the effect of married female workers' protean career orientation toward career satisfaction based on JD-R theory, WH-R model. Through this, we tried to grasp a single comprehensive model of controlled mediating effects rather than verifying simple mediating effect of work-family balance and simple manipulation effect of mobile device use after work. The results of a study on 278 married female employees who are engaged in domestic manufacturing and major service industries are as follows. First, the protean career orientation has a positive effect on the work-family balance and career satisfaction. Second, the moderated mediation effect on the use of mobile devices after work by work-family balance was proved in the protean career orientation and career satisfaction. Based on the results of this study, implications, limitations of the research and directions for future research were discussed.

IS INDIA HEADING TOWARDS TRADE PROTECTIONISM: AN ANALYSIS OF CAROTAR RULES?

With the announcement of Self-Reliant India Mission, the Government of India has announced several policy measures to promote domestic manufacturing to make India, as a hub of global manufacturing. One of its major policy measures is the introduction of Customs (Administration of Rules of Origin under Trade Agreements) Rules, 2020 (CAROTAR Rules). The objective of these rules is to regulate frivolous imports of the third country, which is routing to the Indian market via its FTA partners. These rules have created ‘lots of hues and cry’ among importing and exporting firms due to their regulatory, operational and business implications. This article examines key provisions of CAROTAR rules and their implications to India’s foreign trade sector in general and exporting and importing firms in particular. Findings show that CAROTAR rules are highly protective and regressive in nature and designed to safeguard the domestic manufacturing industry. The intent and content of these rules clearly demonstrate that importing firms are subject to strict regulatory compliance to claim preferential benefit under India’s existing trade agreements. New rules will increase the cost of importing inputs and components thereby affecting India’s trade competitiveness. Keywords: CAROTAR rules, free trade agreements trade protectionism, customs, imports, global value chains.

Fabrication and Characterization of Acrylonitrile Butadiene Rubber and Stitched E-Glass Fibre Tailored Nano-Silica Epoxy Resin Composite

In this research, the role of acrylonitrile butadiene rubber (ABR) and nano-silica along with stitched E-glass fibre in epoxy composite was investigated. The main objective of this present study is how the additions of ABR and nano-silica particle influences in the mechanical, drop load impact and fracture toughness properties of glass-epoxy composite. The layering of rubber sheet for improving the reinforcing effect is a novel approach in reinforced plastic. The composites were prepared using various stacking sequence of ABR and E-glass fibre with nano-silica toughened epoxy resin. The composites were characterized using ASTM standards. According to mechanical properties the composite designation FAF2 symmetric arrangement gives better overall (rank of 97) properties. Similarly, the composite designation AFA2 gives very higher penetration resistance against the fast moving impactor. The fracture toughness behaviour of the composite shows higher energy release rate of 3.8 MJ/m2 and fracture toughness of 22 MPa for 3 vol.% of nano-silica particle dispersed FAF epoxy composite. The SEM micrographs show improved adhesion of 3 vol.% nano-silica with fibre and ABR in composites. The penetration improved rubber based epoxy composites could be used in armour based device, automobile body parts and domestic product manufacturing industries.

A Study on the Impact on Management Performance of Hidden Champions Using Blue Ocean Strategy to Develop a New Product

This study is an empirical research to find out the effect on the management performance of hidden champions of food manufacturing companies when using blue ocean strategy for new product development. In order to achieve the purpose of this study, we conducted a questionnaire survey on hidden champions in the domestic food manufacturing industry and proceeded empirical analysis. When small and medium-sized enterprises in food manufacturing industries develop a new product, searching for non-customer, rebuilding the market boundary, and linking the external networks have a significant impact on their management performance. However, the fair procedure did not have a significant effect on the management performance. In terms of relative influence, rebuilding the market boundary was most affecting, followed by searching for non-customer and linking the external networks. On the other hand, this study implicated the management performance of hidden champions of food manufacturing industries when new products is developed by using the blue ocean strategy. Obtained results are as follows. If small and medium-sized enterprises of food manufacturing industries develop new products, it will be able to improve the management performance by utilizing strategies such as searching for non-customer, rebuilding the market boundary, and linking the external networks. In particular, the rebuilding the market boundary among the blue ocean strategies has a relatively high impact on management performance.

Environmental Regulation, Technological Innovation, and Export Competitiveness: An Empirical Study Based on China’s Manufacturing Industry

A current and universal challenge, particularly in developing nations, is the establishment of effective environmental regulation policies that protect the ecological environment without adversely affecting the international competitiveness of the domestic manufacturing industry. To deal with this dilemma, this study investigates the export competitiveness of China’s manufacturing industry from the viewpoint of export value added. The Porter hypothesis is applied for an empirical investigation of the effect of environmental regulation on export competitiveness and to determine the presence of intra-industry heterogeneity. Furthermore, this study seeks to understand the mechanisms through which environmental regulation affects export competitiveness by exploring the two main approaches to technological innovation. The findings reveal that environmental regulation has a promotion effect of approximately 2% on the export competitiveness of China’s manufacturing industry; however, this effect is non-linear and displays a “U-shaped” tendency, indicating that certain prerequisites must be fulfilled to validate the Porter hypothesis. In addition, the effect of environmental regulation displays significant intra-industry heterogeneity, which is evident primarily in heavily polluting sub-industries and to a lesser extent in moderately polluting sub-industries but insignificant in lightly polluting sub-industries. Environmental regulation also differs significantly in the mechanisms through which it affects different approaches to technological innovation. Independent research and development is affected by environmental regulation through the compliance cost effect, which limits export competitiveness, while technology introduction is affected by the innovation offset effect, which favors export competitiveness. These findings offer political implications for the sustainable development of the ecological environment and foreign trade.

Is there a trade-off between energy consumption and employment: Evidence from India

Following India’s efforts to mitigate the emission of greenhouse gases, there has been a transition from fossil fuels to clean energy sources, such as solar and wind, in the energy portfolio. The renewable energy sector is widely acknowledged as a fertile ground for employment creation, as it is labour-intensive. Against this backdrop, the main objective of this paper is to provide an empirical explanation of how the growth of renewable energy sources, particularly solar photovoltaic (PV) technology, affects employment creation in India. The findings reveal that, despite a substantial investment in India’s solar PV technology, the number of jobs created by the sector declined marginally from 164000 in 2017–114000 in 2018. India’s estimated employment elasticity is just 0.004, implying that the level of employment does not show a significant positive response to changes in installed capacity. Almost 60 per cent of the global solar PV workforce is in China, which has become the leading country both in terms of installed capacity of global solar PV technology and manufacturing of solar PV cells and modules. The wide disparity in solar PV employment between India and China is explained by the former’s excessive dependence on China for solar PV cells. Alongside climate conservation, India should, therefore, place more emphasis on revitalising the domestic solar manufacturing industry to bring about efficient use of the nation’s untapped resources.

Design and control of condom delivery system

At present, in the domestic condom manufacturing industry, the method of the pin hole detection of the condom is the electric test, and because of the uncertainty of the attitude before the electric test of the condom, the automatic electric test can not be carried out. In order to solve the attitude and order of the condom, the automatic electric test is realized. In this paper, a transfer system based on the Mitsubishi PLC controller is put forward based on the physical property of the condom, and the mutual action of the various sensors and the air cylinder is used to achieve the aim of the research. The delivery system solves the problem of disorder and overlap of condoms, realizes automatic detection, reduces labor cost, and provides an effective system for the transportation of flexible materials.

Explaining the Paradox of Economic Nationalism and Pacifist Free-Trade Ideology Coexisting in Keynes’s Thinking on the International Economy

John Maynard Keynes is known to have frequently changed his opinion on free trade and protection. There have been two contrasting interpretations of Keynes’s thought on the external economic policy, with one considering him essentially a free trader and the other finding him a protectionist. This article elucidates an original coherent explanation for Keynes’s ambiguous thinking on Britain’s external economic policy by observing the contradictory coexistence of economic nationalism and pacifist free-trade ideology among the New Liberals (left-leaning Liberals), of whom he was one. Since the 19th century, Britain had a peculiar political tradition in that the proposal of a protectionist policy almost entirely came from the political right, whereas the political left monolithically supported unconditional free trade under the influence of Richard Cobden’s idealistic internationalism. New Liberals, such as J.A. Hobson and Keynes, were sympathetic to the vision of a balanced national economy in which the manufacturing, rather than the financial sector, played a central role. In this sense, New Liberals had much in common with the historical economists, such as William Cunningham and William Ashley, who supported the Conservative Party’s protectionist campaign. Both Hobson’s theory of underconsumption and Keynes’s theory of effective demand emphasized the importance of domestic, rather than foreign markets. This meant that the New Liberals’ economic thinking was essentially more congruent with a protectionist policy to safeguard domestic manufacturing industries than free trade. Nevertheless, the New Liberals found it extremely difficult to support a protectionist policy because of protectionism’s strong association with right-wing politics in Britain and its incommensurability with their belief in a pacifist free-trade ideology. This dilemma formed the backdrop of Keynes’s allegedly inconsistent attitudes on the external economic policy of his time. JEL classification numbers: B10, B20, B27.
