A cradle-to-gate life cycle assessment provides comprehensive insights into diverse environmental impacts and possible improvements in producing two formic acids.
Floor finishing materials such as floor coverings and floor mats can reduce floor impact noise easily. When an impact was applied to the floor, its finishing material is deformed and the impact force that was applied to the concrete slab is changed. The softer finishing materials were, the more impact force decreased. An experimental study was performed using 14 PVC floor coverings and 16 floor mats to capture the characteristics of impact force and impact noise in the residential buildings.
Abstract. Due to the development of ubiquitous computing environment, wireless sensor network technology has been applied and developed in various fields. However, unlike a typical wireless network, wireless sensor networks operate based on the energy of a sensor node, ie, a battery, so energy consumption must be minimized rather than QoS requirements. In consideration of these issues, the function of the MAC standard of IEEE802.15.4 is supplemented, and the reliability of the wireless sensor network environment and the standardization of the information transmission of the sensor are underway, but it has the disadvantages of slow response as the power consumption decreases and many problems to be solved. In this paper, we propose a new protocol to manage the power efficiently by adding a protocol to receive Beacon dynamically according to the data transmission frequency, it is a study on energy efficiency that can minimize the response speed from sensor node to central data processor.
With performance both as hosts and routers, easy network configuration, and fast response, mobile nodes participating in MANET are suitable for Embedded computing but have vulnerable points, about lack of dynamic network topology due to mobility, network scalability, passive attacks and active attacks which make it impossible to manage continuous security authentication service. In this study, proposes Session key-Encrypted key exchange authentication mechanism for a robust authentication based on MANET and through identify wireless environment security vulnerabilities, currently being used in DH-EKE analyzes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
