An Automated Framework for Detecting Change in the Source Code and Test Case Change Recommendation

Improvements and acceleration in software development have contributed towards high-quality services in all domains and all fields of industry, causing increasing demands for high-quality software developments. The industry is adopting human resources with high skills, advanced methodologies, and technologies to match the high-quality software development demands to accelerate the development life cycle. In the software development life cycle, one of the biggest challenges is the change management between the version of the source codes. Various reasons, such as changing the requirements or adapting available updates or technological upgrades, can cause the source code's version. The change management affects the correctness of the software service's release and the number of test cases. It is often observed that the development life cycle is delayed due to a lack of proper version control and due to repetitive testing iterations. Hence the demand for better version control-driven test case reduction methods cannot be ignored. The parallel research attempts propose several version control mechanisms. Nevertheless, most version controls are criticized for not contributing toward the test case generation of reduction. Henceforth, this work proposes a novel probabilistic rule-based test case reduction method to simplify the software development's testing and version control mechanism. Software developers highly adopt the refactoring process for making efficient changes such as code structure and functionality or applying changes in the requirements. This work demonstrates very high accuracy for change detection and management. This results in higher accuracy for test case reductions. The outcome of this work is to reduce the development time for the software to make the software development industry a better and more efficient world.

The spatial spillover effect of ICT development level on regional CO2 emissions

Information and communication technology plays an essential role in affecting CO2 emissions and promoting green and sustainable development. This paper empirically examines the effect of the level of urban ICT development on CO2 emissions using panel data for Chinese cities from 2010 to 2020. On this basis, a spatial Durbin model is used to analyze the spatial spillover effects of ICT development level affecting regional CO2 emissions, and its direct, indirect and overall effects are further analyzed. The conclusions of the study are as follows. (1) The CO2 emissions of Chinese cities are correlated by spatial distance and show high-high or low-low clustering characteristics. (2) ICT development can reduce CO2 emissions in the region and increase CO2 emissions in neighboring regions. This conclusion still holds after several robustness tests. And when the level of ICT development increases by 1 standard deviation, CO2 emissions are reduced by 64%. (3) The mechanism of action shows that ICT can influence regional CO2 emissions through its technological innovation effect and industrial upgrading effect. (4) The impact of ICT development on regional carbon emissions is characterized by significant heterogeneity depending on the city's geographical location and whether or not environmental information is publicly available.

IMPACT Of LEATHER & LEATHER PRODUCTS IN NIGERIAN ECONOMIC GROWH AND BUSINESS DEVELOPMENT

The production and sale of leather products have played a significant role in Nigeria’s economic growth and business development. However, the industry faces challenges such as inconsistent policies, infrastructure deficiencies, and the need for technological upgrades also the study is designed to access the importance roles of leather products to economic growth and development. The results of the research findings showed that availabilities of tanneries should be discouraged foreign products and encourage patronizing made in Nigeria leather products, and diversification of the leather products and leather goods which is the second command revenue to Nigeria economy. Use of locally available materials for income generation, and solving unemployment among the teeming youths aim of the study, hides and skin conversion into leather product will lead to economy development of Nigeria. There’re needs for both public and private partnership in order to encourage leather and leather product improvement, technical and extension support to development an effective system in leather processing and to finishing stage. Generally, the leather and leather products industry play a prominent role in the world’s economy. UNIDO estimated that world leather export is dominated by developing countries while developed countries dominate export of Finished Leather Products. Global estimate of leather production is about 23 billion square foot annually. Asia accounts for about 57 percent of heavy leather production and 44 percent of light leather production. Europe accounts for 17 percent and 24 percent of global heavy leather and light leather production, respectively while Africa contributes the least accounting for one per cent of heavy leather and 4 percent of light leather production.

Controlling Industrial Air-Pollutant Emissions under Multi-Factor Interactions Based on a Developed Hybrid-Factorial Environmental Input–Output Model

A hybrid-factorial environmental input–output model (HEIM) is proposed for controlling industrial energy-related air pollution. HEIM has the advantages of analyzing industrial air-pollutant emission system (IAES) performance, quantifying key factors’ individual and reciprocal effects on the system, generating optimal system planning strategies under multiple scenarios. HEIM is then applied to Fujian province, which is a special economic development region in China. The significant findings are as follows: (i) the main sectors of pollutants’ (NOx, SO2, PM and VOCs) emissions are electricity supply (ELE), transportation (TRA), nonmetal minerals (NON), chemical products (CHE) and metal processing (MET); (ii) the proportion of air pollutants (NOx, SO2 and PM) emitted from energy activities can reach 83.8%, 88.6% and 68.1% of the province’s total emissions, implying that it is desired for industrial activities to improve the energy efficiency and promote cleaner production; (iii) the system robustness was between 0.287 and 0.321 (maximum value is 0.368), indicating the emission structure of IAES was not healthy; (iv) the contributions of the key factors to air-pollutant emission equivalent are NOx emission (51.6%) > ELE coal consumption (25.8%) > SO2 emission (12.5%); (v) the contributions of the key factors affecting system robustness are equipment manufacturing’s (EQU) direct consumption coefficient (81.4%) > CHE coal consumption (11.7%) > NON coal consumption (5.0%). The optimal strategies should strictly control ELE coal consumption (replaced by clean energy) and strictly limit NOx and SO2 emissions (e.g., technology upgrade) from the main sectors.

A novel plumes treater for solid rocket motors during hot‐firing tests using ice tunnel structure

AbstractAiming at the perniciousness of the exhausted plumes from solid rocket motors during hot‐firing tests, a novel plume treater is proposed using the ice tunnel device. The feasibility and effectiveness of this ice tunnel treater were successfully verified by tests on two solid rocket motors, XX 127 and XX 500, with different fuel charges of about 1.5 and 700 kg, respectively. Results show that the plume temperature could be greatly reduced from around 2000 to below 100°C through the ice tunnel for both motors, and the effect of noise reduction as well as the elimination of gaseous hydrogen chloride was also measured to be available in the test of XX 500, indicating the new ice tunnel treater could quickly achieve the “three reductions” of high temperature, serious noise, and gas pollution of the solid rocket motor emissions. Besides, a numerical model considering the factors of air entrainment, afterburning, convective heat transfer, radiation heat transfer, and phase change was established to investigate the flow and heat transfer behaviors within the ice tunnel. The plume temperature at the outlet of the ice tunnel was in good agreement with the experimental data. The intensity of afterburning is mainly determined by the amount of entrained air and the CO concentration. The cooling capacity of the ice tunnel is mainly contributed by convection, air entrainment, and particle radiation. This work could provide new ideas and references for the technological upgrade of the ground test platforms for solid rocket motors.

Technology Upgrade Assessment for Open-Pit Mines through Mine Plan Optimization and Discrete Event Simulation

Digital technologies are continually gaining traction in the mining and mineral processing industries. Several studies have shown the benefits of their application to help improve various aspects of the mineral value chain. Nevertheless, quantitatively assessing new technologies using a holistic approach is vital to evaluate whether the potential localized benefits ultimately translate to an overall increase in project net present value (NPV). This study develops an integrated system-wide methodology for open-pit mines, supporting the technoeconomic assessment of implementing new technology that impacts strategic and operational timeframes. The first part of the framework relies on a state-of-the-art mine plan optimization algorithm that incorporates geological uncertainty. The resulting outputs are then fed into the discrete event simulation portion of the framework (second part) to maximize plant throughput using alternate modes of operation (blending strategy) and operational stockpiles to deal with unexpected changes in ore feed attributes. Sample calculations loosely based on a gold deposit located in the Maricunga belt, Chile, are presented in the context of evaluating different intelligent ore sorting technology options.

Impact of Foreign Direct Investment on Indian Economy

Foreign direct investment (FDI) is an instrument for economic growth; it strengthens domestic capital, productivity and employment. FDI in India has got an important role in the development of the Indian economy. FDI in India has enabled India to achieve a certain degree of financial stability, growth and development in various ways. It has allowed India to focus on the areas that needed a boost and economic attention, and to address the various problems that continue to challenge the country. India has worked a lot to attract FDI from the world’s major investors. FDI is vital in the up gradation of technology, skills and managerial capabilities in various sectors of the economy. With globalization, developing countries, particularly those in Asia, have been witnessing an immense surge of FDI inflows during the past two decades. India with its considerable market potential and a liberalized policy regime has sustained its attraction for foreign investors. This research paper aims to observe the impact of FDI on Indian economy, predominantly after two decades of economic reforms. The paper provides the major policy implications from this analysis. The attraction of foreign direct investments (FDI) is often emphasised as a precondition for a successful economy by most governments of less developed countries. The objective of the paper is to evaluate economic impacts of FDI

NUV-HD SiPMs with metal-filled trenches

In this paper we present the performance of a new SiPM that is sensitive to blue light and features narrow metal-filled trenches placed in the area around the single-photon avalanche diodes (SPADs) that allow an almost complete suppression the internal optical crosstalk. In particular, we show the benefits of this technological upgrade in terms of electro-optical SiPM performance when compared to the previous technology which had only a partial optical screening between the SPADs. The most relevant effect is the much higher bias voltage that can be applied to the new device before the noise diverges. This allows to optimize and improve both the photon-detection efficiency and the single-photon time resolution. We also coupled the SiPMs to LYSO scintillators to verify the performance for possible application in Positron-Emission Tomography. Thanks to the better electro-optical features we were able to measure an improved coincidence time resolution. Furthermore, the optimal voltage operation region is substantially larger, making this SiPM more suitable for real system application where thousands of channels have to provide stable and reproducible performance.

Validation of Low Cost Patient Specific Implant Design Using Finite Element Analysis (FEA) for Reconstruction of Segmental Mandibular Defects: A Case Report and Literature Review.

Mandibular continuity defects can cause functional and cosmetic deformities affecting a patient's quality of life. Reconstruction of such defects can be intricate even for the most seasoned maxillofacial surgeons. Reconstruction plates were the standard of care in the past, followed by a secondary reconstruction using autogenous grafts. Novel technological upgrades like customized computer-designed patient-specific implants (PSIs) have overtaken these stock reconstruction plates to enhance the aesthetics and address the individual clinical situation. Affirmation of the above plate design using biomechanical analysis can further improve the efficacy of PSIs. The present case report describes a novel combination of an autogenous graft and a low-cost patient-specific implant with the prosthesis design validated using finite element analysis. The authors have also reviewed the biomechanical evaluation of PSIs design and its uses in treating mandibular continuity defects. Use of FEA helped to inspect the potential weakness and stress distribution through out the implant due to this there was no sign of hardware failure.

Technological Innovation, Product Quality and Upgrading of Manufacturing Value Chain: Empirical Evidence from China

The aim of this research is to investigate the relationship between enterprise technological innovation, export product quality, and the upgrading of the manufacturing value chain. The study is based on panel data from Chinese manufacturing enterprises between 2000 and 2013 and uses a multi-dimensional fixed-effect method to analyze the moderating effect of enterprise export product quality on the relationship between technological innovation and the upgrading of the manufacturing value chain. The results show that technological innovation significantly promotes the upgrading of the manufacturing value chain. The regression analysis indicates that a 1% increase in enterprise technological innovation leads to a 0.28% increase in the upgrading of the manufacturing value chain. Similarly, the study demonstrates that improving the quality of exported products significantly enhances the manufacturing industry’s status in the global value chain. The regression analysis reveals that a 1% increase in the quality of exported products leads to a 0.14% increase in the upgrading of the manufacturing value chain. Moreover, the research identifies a threshold value of 0.4438 for the moderating effect of enterprise export product quality on the impact of technological innovation on the upgrading of the manufacturing value chain. When the quality of exported products is below the threshold value, it has a strong positive regulatory effect on technological innovation, promoting the upgrading of the manufacturing value chain. However, once the quality of exported products exceeds the threshold value, its regulatory effect becomes insignificant. The study’s findings have important implications for enterprises looking to overcome the “dilemma of scientific and technological innovation” and promote the intelligent development of the manufacturing industry. The research conclusions have strong reference value for promoting the combination of technology innovation and business model innovation in manufacturing enterprises. This will allow for climbing the high-end links of the global value chain and achieving sustainable development.

Technological capabilities and global value chains: insights from Spanish SMEs in the hotel industry

PurposeThis study explores the role of international tour operators as the agents assuming the governance and the upgrading of the tourism global value chains (TGVCs), with a special focus on their influence on the development of technological capabilities (TCs) in the hotel industry.Design/methodology/approachThe data used in this article originates from a survey carried out in 2016 on Spanish small and medium-sized hotel companies. An ordinal regression analysis is employed to test the hypotheses proposed in this research.FindingsThis study finds that tour operators exert a positive effect on the technological upgrading process in the hotel industry by stimulating small and medium-sized enterprises (SMEs) to invest in TCs. The causal mechanisms through which these effects take place differ across the various stages of the relationship between hotel companies and tour operators.Practical implicationsThe results have implications both for hotel management in terms of how hotels take advantage of technological upgrading to become more competitive, and for public administrations in terms of what measures can boost the development of hotel TCs in order to increase their added value.Originality/valueTo date, very few studies have analysed the tourism sector based on the influence on the development of TCs of SME hotels by combining GVC concepts and the resource-based view. It is also the first time that the causal mechanisms are shown to explain such influences.

Outcomes after revision of Advanced Bionics Clarion 1.2 cochlear implants

Introduction Cochlear implant reimplantation (CIR) for external processor upgrade or device failure is becoming increasingly common as the population of cochlear implant recipients ages. Patients with Advanced Bionics (AB) Clarion 1.2 cochlear implants may undergo CIR for device age/failure or desired technology upgrade so that they may use newer external processors that have improved connectivity features. The objective of this study was to evaluate audiologic outcomes for patients who were initially implanted with an AB Clarion 1.2 internal device and underwent CIR for technology upgrade or device failure. Methods Retrospective chart review was performed at a single academic medical center for patients (pediatric and adult) with an AB Clarion 1.2 internal device who underwent CIR to a later generation AB internal device and had available audiologic data. Results Forty-eight individuals with a Clarion 1.2 implant underwent CIR. Pre- and post-CIR speech understanding did not change for AzBio (p-value = 0.11, mean change = 12.1%, 95% CI = -2.9-27.2%), CNCw (p-value = 0.74, mean change = -1%, 95% CI = -10.4-12.4%), or HINT (p-value = 0.12, mean change = 19.9%, 95% CI = -2.6-42.4%) scores. Pure-tone averages improved following CIR (p-value < 0.01, mean change = 4.3 dB, 95% CI = 1.5-7.1 dB). Conclusions Revision of AB Clarion 1.2 cochlear implants does not significantly worsen audiologic outcomes and may improve hearing in some individuals, but individual patient-level outcomes are variable.

Dual-wavelength excited luminescence properties of NaYbF4:Er3+ for flexible anti-counterfeiting

Multiple encryption of information is the key to the upgrade of anti-counterfeiting technology. However, developing reliable multimode anti-counterfeiting materials is still a challenging work. Herein, a series of Er-doped NaYbF4 microprisms was synthesized. The as-prepared microprisms could show variable emission from red to yellow under the irradiation of 980 nm, and exhibit red at 365 nm UV light, respectively. Near-infrared excitation is achieved through the upconversion process of Er–Yb pairs, while UV excitation is achieved through Er ions. Its crystal structure, morphology, and photoluminescence features were analyzed. To broaden its practical application, the powders were combined with TPU to form a film with excellent stretchability, transparency, and water resistance. Our work demonstrates a dual-wavelength excited luminescence material, providing a practical reference for the application of anti-counterfeiting materials.

Firm-level Technological Upgrading Process in Low-tech Industries: the case of Clothing Industry in Brazil

There is a considerable amount of research on technological upgrading and innovation. However, the majority of studies tend to focus on R&amp;D and patents aspects in high-tech industries. Seeking to contribute to rebalancing the analysis, we examine how occurs technological upgrading path in a low-tech industry, the clothing industry from emerging market. The low-tech industries represent around 90% of the economy of emerging countries, such as Brazil. The research design is operationalized from depth individual case study. The findings show that the clothing industry, even though characterized as low-tech, has not remained technologically stagnant, developing innovative activities and a path-follower. However, although it can be considered innovative, the industry shows little association with 4.0 technologies. The research questions biases in extant research and policy debate towards certain types of innovative capabilities, industries, and taxonomies that limit the understanding of innovation and technological catch-up in different industrial settings.

The Coupling and Driving Effect of Financial Technology and Green Venture Capital

The “supply side” of financial technology is coupled with the “demand side” of green venture capital development, which has played a guiding role in technological change and industrial upgrading and will promote great changes in the financial industry. As an important part of the financial industry, green investment has high-risk characteristics, and financial technology plays a key role in reducing the risk of green investment. In this paper, firstly, by extracting the data of 31 provinces, municipalities, and autonomous regions from 2013 to 2020, the measurement system of financial technology and green venture capital is constructed, and then the regression model is constructed to empirically analyze the relationship between financial technology and green venture capital, and the robustness test and the calculation of coupling degree are carried out. Finally, based on the analysis results, some feasible suggestions are put forward in order to improve the coupling degree between financial technology and green venture capital.

The influence of digital economy development on urban carbon emission intensity in the Yangtze River Economic Belt: Mediating mechanism and spatial effect

The iterative upgrading of digital technology and the implementation of “carbon-peaking and carbon neutrality” national strategy provide an opportunity for the synergistic integration of digital economy and green economy in China, thus, whether the development of digital economy can curb urban carbon emission intensity (CEI) remains to be answered. Based on the panel data of 110 cities in the Yangtze River Economic Belt (YREB) region from 2011 to 2020, this paper investigated the impact of digital economy on CEI by using the dual fixed-effect model, the mediating mechanism model and the spatial Durbin model. The main results are as follows: (1) The development of digital economy in the YREB region can lower down CEI, promote the rationalization and upgrading of industrial structure, and improve cities’ green innovation capacity; (2) CEI was reduced through the intermediary effect of industrial structure optimization and upgrading and green technology innovation; (3) Digital economy shows a significant positive spatial correlation, and exerts a spatial spillover effect of reducing CEI in surrounding cities with obvious spatial heterogeneity; (4) Digital economy has a stronger inhibitory impact on CEI in the downstream cities and cities within the urban agglomerations; (5) In addition to digital infrastructure, the remaining components of digital economy, directly and indirectly, diminish CEI. At last, according to the research findings, suggestions for digital economy development in the YREB region are put forward.

Modeling the linkage between climate-tech, energy transition, and CO2 emissions: Do environmental regulations matter?

The transition from conventional energy to clean energy is the ultimate strategy to reduce global CO2 emissions. In this regard, climate technologies (climate-tech) can pave the way toward achieving the capabilities required to promote alternative energy and energy saving. In addition, environmental regulations can support technological upgrading, energy transition, and emissions reduction to promote sustainable development. With this in view, this study investigates the impact of climate technologies (climate-tech) and energy transitions on CO2 emissions in the European Union (EU) member countries. Further, we examine the role of environmental regulation in the relationship between climate-tech, energy transition, and CO2 emissions. The empirical analysis is conducted based on international panel data for 26 EU countries ranging from 1994 to 2019, and the Common Correlated Effects Mean Group (CCE-MG) method is employed to estimate the coefficients of the variables. The outcomes of the analysis indicate that both climate-tech and energy transitions mitigate environmental degradation by reducing carbon emissions. Additionally, environmental regulations are found to be an effective monitoring and controlling tool that can significantly reduce CO2 emissions. Moreover, economic growth and urbanization as control variables contribute to increasing CO2 emissions, thus negatively affecting environmental sustainability. The causal analysis demonstrates that decision-making trends related to climate-tech, energy transition, and environmental regulations influence CO2 emissions. Conversely, strategies for coping with CO2 emissions and climate change will affect energy transitions and environmental regulations. In light of these analytical findings, this paper proposes that EU countries should vigorously develop climate-related green technologies and actively promote the energy transition process along with the implementation of environmental regulations for sustainable development.

Spatio-temporal evolution and influencing factors of synergizing the reduction of pollution and carbon emissions - Utilizing multi-source remote sensing data and GTWR model

Grasping current circumstances and influencing components of the synergistic degree regarding reducing pollution and carbon has been recognized as a crucial part of China in response to the protection of the environment and climate mitigation. With the introduction of remote sensing night-time light, CO2 emissions at multi-scale have been estimated in this study. Accordingly, an upward trend of “CO2-PM2.5” synergistic reduction was discovered, which was indicated by an increase of 78.18% regarding the index constructed of 358 cities in China from 2014 to 2020. Additionally, it has been confirmed that the reduction in pollution and carbon emissions could coordinate with economic growth indirectly. Lastly, it has identified the spatial discrepancy of influencing factors and the results have emphasized the rebound effect of technological progress and industrial upgrades, whilst the development of clean energy can offset the increase in energy consumption thus contributing to the synergy of pollution and carbon reduction. Moreover, it has been highlighted that environmental background, industrial structure, and socio-economic characteristics of different cities should be considered comprehensively in order to better achieve the goals of “Beautiful China” and “Carbon Neutrality”.
