Analysis of the innovation of the financial management under the e-commerce environment

The traditional financial management model has been unable to meet the requirements of the economic development on the enterprises, so it is necessary to find a new way out for the financial management of the enterprises, Although the e-commerce has many advantages in the implementation of the financial management of the enterprises, there are still some problems that cannot be ignored. Each enterprise must first base itself on the development of the enterprise itself, and then should take some measures. Firstly, the author of this paper elaborates the current situations of the development of the e-commerce technology in China, and then analyzes the problems in the financial management of the enterprises under the e-commerce environment, and finally puts forward some suggestions on the innovation of the financial management under the e-commerce environment

A Cooperative Jamming Scheme Based on Node Authentication for Underwater Acoustic Sensor Networks

Cooperative jamming(CJ)is one of the important methods to solve security problems of underwater acoustic sensor networks(UASNs).In this paper,we propose a Cooperative Jamming Scheme based on Node Authentication for UASNs to improve the effect of CJ by selecting suitable jamming source for found illegal nodes.In the node authentication,all nodes will be identified by their trust value(TV).TV is calculated according to three types of evidence:channel-based trust evidence,behavior-based trust evidence and energy-based trust evidence.Besides,to deal with cases where legal nodes may be suspected,the historical TV and trust redemption will be considered when calculating TV.In cooperative jamming,according to the link quality,several nodes are selected to jam illegal nodes.Both simulation and field experiment show that the proposed scheme can accurately find the illegal nodes in the time-vary channel and improve the security of the network.

Towards Incremental Deployment of Diverse Network Architectures on the Internet

In the past decades, many cleanslate future network architectures have gained limited deployment in current Internet, due to the stability and rigidity of TCP/IP, the narrow waist of the Internet. We first propose three principles that the future Internet architecture should obey to be well-defined network architecture, i.e. supporting service innovation and enabling evolvability. By abstracting different modes from TCP/IP network and SDN technology, we argue that the centric-distributed-centric(CDC) mode has great potential for the well-defined future network architecture in which diverse network architectures could be incrementally deployed and coexist with each other. Prototype system regulated by CDC mode was developed. Experimental results reveal that CDC can support diverse architectures to coexist in the current Internet and thus enables the Internet to evolve.

A Stiffness-Tunable Composite with Wide Versatility and Applicability Based on Low-Melting-Point Alloys

Flexible materials are essential in bionic fields such as soft robots.However,the lack of stiffness limits the mechanical performance of soft robots and makes them difficult to develop in many extreme working conditions,such as lifting and excavation operations.To address this issue,we prepared a stiffness-tunable composite by dispersing low-melting-point alloy into thermosetting epoxy resin.A dramatic and rapid change in stiffness was achieved by changing the state of matter at lower temperatures,and accurate control of the composite modulus was achieved by controlling the temperature.When the alloy content is at 30vol%,the tensile modulus changes 41.6 times,while the compressive modulus changes 58.9 times.By applying the composite to a flexible actuator,the initial stiffness of the actuator was improved by 124 times,reaching 332 mN/mm.In addition,the use of stiffness-tunable materials in the wheel allowed for timely changes in the grounding area to improve friction.These flexible materials with manageable mechanical properties have wide applicability in fields including bionics,robotics,and sensing.Our findings provide a new approach to designing and developing flexible materials with improved stiffness and controllability.
