Theoretical analyses and experimental studies of the mechanisms of melting film formation are performed. The results show that frictional heating is the dominant mechanism because temperature behaves in the manner predicted by the theory of frictional heating. A study of the active technology for anti-skid is also made. Conclusions indicate that adjusting tire pneumatic pressure can improve the control stability and the travelling safety of an ice-automobile. 展开更多

Governments are implementing E-Government systems to match the other services due to the rapid worldwide development. Therefore, public sectors interact with many individuals;utilizing this technology lowers costs, enhances services, boosts efficiency, and saves time. The Government of Saudi Arabia has had various obstacles in serving its populace. Poor service delivery and excessive Government operating costs resulted from this manual service delivery. As a result, the Government launched the E-Government systems, which provide services more quickly. As a result, the report covered Saudi Arabia’s efforts to adopt E-Government, its difficulties, and its objectives to advance the 2030 vision. This study examined the adoption of E-Government systems using the Unified Theory of Acceptance and Use of Technology (UTAUT) in Saudi Arabia. A sample size of 200 was estimated using the Convenience approach and received 58% of the response from employees and end-users of the E-Government systems. Data were analyzed using MS-Excel and SMART PLS for testing the hypothesis and applying the Partial Least Square approach. The results of the hypothesis testing reveal several meaningful relationships, including relative benefits, compatibility, security, management support, performance expectations, perceived Usefulness of E-Government, ease of use by reducing uncertainty to E-Government, and IT infrastructure by reducing language on E-Government adoption. 展开更多

There exist serious problems in the trustworthiness (security, reliability, controllability and manageability) of the Internet. In order to solve these problems, a new-generation network architecture model, based on the research of the basic theories of new-generation Internet system, is proposed. The solution creates a switching routing model and theory for the new-generation Internet system, and defines the access identifier, generalized switching routing identifier and their mapping principles. It also establishes a pervasive service system architecture and theory, defines the service identifier, connection identifier and their mapping principles. This paper discusses key technologies for the new-generation Internet system, such as access control and management, trusted routing and Quality of Service (QoS), multi-streaming, and network monitoring and management. 展开更多

Purpose: This study aims to explore factors affecting continuance intention of mobile reading. Design/methodology/approach: Drawing on the unified theory of acceptance and use of technology (UTAUT), and integrating perceived enjoyment, we put forward a theoretical research model of factors affecting continuance intention of mobile reading. Using 186 valid data collected through a questionnaire survey, we conducted data analysis with the partial least squares structural equation modeling (PLS-SEM). Findings: The results show that performance expectancy, effort expectancy, social influence and perceived enjoyment all have positive impacts on continuance intention. Among them, perceived enjoyment has the most significant effect on continuance intention, followed by performance expectancy. In addition, effort expectancy significantly influences perceived enjoyment. Contrary to our expectation, facilitating conditions have no impact on continuance intention. Practical implications: This study could help mobile data service providers to foster users' continuous usage of mobile reading. Research limitations: This study focused only on the effect of perceived enjoyment as an internal motivation on continuance intention of mobile reading, and other possible factors were not considered. Also, continuance intention may be different from the actual behavior. Furthermore, data of student users was collected from one university in China, and was cross-sectional, while working samples were not considered. Originality value: This study considers the effects of both external and internal motivation on continuance intention of mobile reading. The results highlight the role of perceived enjoyment in building users' continuance intention of mobile reading. 展开更多

E-commerce present opportunities and challenges for businesses, especially for micro-enterprises. This paper proposed a theoretical framework that in line with the unique characteristics of E-commerce acceptance in micro-enterprises in Chengdu, which is based on the unified theory of acceptance and use of technology (UTAUT) model. The extending UTAUT model includes key constructs of performance expectation, perceived behavioral control and the characteristics of owner-managers. 展开更多

User acceptance is one of the key fundamentals for development and success of mobile commerce (m-commerce). Based on the revised unified theory of acceptance and use of technology (UTAUT) model, we described a theoretical framework that incorporates the unique characteristics of m-commerce to enhance our understanding of m-commerce acceptance and usage in China. The revised UTAUT includes the characteristics of m-commerce, inclusion and consideration of information system user satisfaction theory, and Chinese culture and context. 展开更多

The mobile search, a combination of a web search engine and a mobile communication system, is viewed as the most influential application in the 3G era. Therefore, mobile search service providers are eager to know which factors most influence user acceptance of mobile searches. Based on the characteristics of mobile searches and a review of previous information technology acceptance research, this study integrates the task technology fit model and the unified theory of acceptance and use of technology model to develop a mobile search acceptance model and empirically tests this model. This study finds that, for mobile searches, the performance expectancy, social influence, and perceived cost all significantly influence use intention and the performance expectancy increases with the increasing user's experience and higher tasktechnology fit degree. The effort expectancy is found to not affect the use intention of mobile searches and the users' gender does not have a significant moderating effect on the use intention. The results are then used to develop suggestions for mobile search providers to promote their application and development. 展开更多
