Rapid industrial development in recent times has increased the demand for light-weight materials with high strength and structural integrity. In this context, carbon fiber-reinforced plastic (CFRP) composite materials are being extensively used. However, laminated CFRPs develop faults during impact because CFRPs are composed of mixed carbon fiber and epoxy. Moreover, their fracturing behavior is very complicated and difficult to interpret. In this paper, the effect of the direction of lamination...

Due to their morphology, electrochemical stability, and function as a conducting carbon matrix, graphene nanosheets (GNS) have been studied for their potential roles in improving the performance of sulfur cathodes. In this study, a GNS/sulfur (GNS/S) composite was prepared using the infiltration method with organic solvent. The structure, morphology and crystallinity of the composites were examined using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The...

This study discusses two canceled dam projects, Youngwol Dam in South Korea and Two Forks Dam in Colorado of the United States. Both of them illustrate how the new paradigm applies to regional water projects because they became victims of environmental opposition in the new paradigm. While the cases have no apparent close relationships and they occurred in different decades, they offer interesting comparisons. They were basically struggles between water development coalitions and environmental...

Researchers found that the teachers’ self-efficacy can help to promote the constructivist approaches of engaged teaching learning activities such as group works and better classroom management. However, few studies have focused particularly on examining science teachers’ self-efficacy on student engagement but not toward three dimensions of behavioral, cognitive and emotional engagement of learning. In this sense the major goal of this study was to develop a reliable, valid, and efficient...

As an effective means of price discrimination, some suppliers offer credit periods to the buyers in order to stimulate the demand for the product they produce. The availability of the credit period from the supplier enables the buyer to choose his selling price from a wider range of price option. Since the buyer's lot-size is affected by the customer's demand rate of the product, the problems of determining the selling price and the lot-size are interdependent and must be solved simultaneously....

This study examined the current situation of foreign language education, teacher training, and education in Korea and China. The analysis and comparison of both countries’ educational policies, problems, and improvement strategies revealed several aspects that require attention. When foreign language education policies are established and enforced in the future, more attention should be given to the rigorous systematization of foreign language curriculum. Furthermore, in the context of...

Cloud computing is an emerging technology. It is a basic paradigm which satisfies all the needs of a customer and it may even serve as a fifth utility in near future. In general it refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. The data center hardware and software is known as a cloud. A huge amount of data is being processed and shared. So, while we are sharing a large amount of data...

The collection of the many mobile nodes forming a short lived infrastructure with the help of any centralized administration. Since there's a random and dynamic modification in topology due to the quality of host, so the requirement for a study dynamic routing protocol is needed. Mobile ad-hoc network have the attributes like wireless affiliation, continuously dynamic topology, distributed operation and simple deployment. It establishes a short lived affiliation wherever nodes will be part of or...

Ensuring the security of cloud computing is a major factor in the cloud computing environment which has many benefits in terms of low cost and accessibility of data, as users often store sensitive information with cloud storage providers, unaware that these providers may be compromised. Dealing with “single cloud” providers is predicted to become less popular with customers due to risks of service availability failure and the possibility of malicious insiders in the single cloud. A movement...
