Prophet_TD Routing Algorithm Based on Historical Throughput and Encounter Duration

Opportunistic networks are self-organizing networks that do not require a complete path between the source node and the destination node as it uses encounter opportunities brought by nodes movement to achieve network communication.Opportunistic networks routing algorithms are numerous and can be roughly divided into four categories based on different forwarding strategies.The Prophet routing algorithm is an important routing algorithm in opportunistic networks.It forwards messages based on the encounter probability between nodes,and has good innovation significance and optimization potential.However,the Prophet routing algorithm does not consider the impact of the historical throughput of the node on message transmission,nor does it consider the impact of the encounter duration between nodes on message transmission.Therefore,to improve the transmission efficiency of opportunistic networks,this paper based on the Prophet routing algorithm,fuses the impact of the historical throughput of the node and the encounter duration between nodes on message transmission at the same time,and proposes the Prophet_TD routing algorithm based on the historical throughput and the encounter duration.This paper uses the Opportunistic Networks Environment v1.6.0(the ONE v1.6.0)as the simulation platform,controls the change of running time and the number of nodes respectively,conducts simulation experiments on the Prophet_TD routing algorithm.The simulation results show that compared to the traditional Prophet routing algorithm,on the whole,the Prophet_TD routing algorithm has a higher message delivery rate and a lower network overhead rate,and its average latency is also lower when node density is large.

在Encounter中实现网格+局部树的时钟设计流程

本文提出了一种新的方法,可以在Encounter中实现全局网格加局部树(MLT)流程。通过在时钟设计流程中利用CTS和时钟网格的优势,可以确保MLT具有更小的偏差,并进一步优化网格结构以降低功耗。在全局网格结构中,MLT可以提供真实的负载累加值,而不是估计值。这一流程还有一个特性就是可以为多电源电压(MSV)时钟设计提供基本的支持。

Signature of Single Binary Encounter in Intermediate Energy He^(2+)-Ar Collisions

We experimentally observe the signature of electron emission resulting from a single binary encounter mechanism in the intermediate collision energy regime of 30 keV/u He2＋ on argon. Electron emission spectra in the transfer ionization are obtained and compared with classical calculations from a two-step model considering the initial electron velocity and re-scattering of the binary encounter electron in the recoil potential. Although the present reaction is actually a four-body problem, the model starting from a binary encounter gives out surprisingly good agreement with the experimental data. Our studies show that orbital velocities of the electron affect the emission patterns of ionized electrons significantly.

Development of the Emerging Theory of Encountering Nursing in a Nurse-Nursed Dyadic Relationship (ThENNDyR)

Encounters are celebrated experiences between persons with connectedness in human situations as expectation. While being in a human dynamic and rhythmic interaction, nursing encounters are dyadic relationships illuminated as patterns of an interconnected relationship moving between the nurse and the nursed, and reflecting person-and-otherness events. The purpose of this paper is to describe the theory of Encountering Nursing in a Nurse-Nursed Dyadic Relationship (ThENNDyR) and to illuminate the four nursing practice processes on which the theory is founded: Knowing as appreciating relational moments;Reflecting as engaging moments;Realizing as patterns of living moments;and Transcending as celebrating moments. Nursing practice occurs in moments in which dyadic relationships transpire as nursing encounters. As fleeting as moments are, the four processes of nursing simultaneously take place as understanding conditions that the who and what of the person warrants persons. “Encountering nursing” is a momentary co-existence of persons in a person-and-otherness situation communicating connectedness-interconnectedness in distinct patterning. Interactions in nursing exist as persons remain wholes and complete in the moment.

Review of Intercultural Service Encounters:Cross-cultural Interactions and Service Quality,Edited by Piyush Sharma,Switzerland,Springer,2019,pp.vii+101,€54,99(hbk),ISBN 978-3-319-91940-9;€46(ebk),ISBN 978-3-319-91941-6

Since the 1990s,globalization has aroused people’s attention constantly.Meanwhile,with more and more immigrants,migrant workers,international students,foreign tourists,and business people,cross-cultural interaction has increased dramatically.Consequently,the communication and interaction between service employees and customers from different cultural backgrounds is getting frequent.Services have gotten great profits from the phenomenon which is known as intercultural service encounters(ICSE).For one who has contributed a lot to ICSE,Piyush Sharma in his book Intercultural Service Encounters:Cross-cultural Interactions and Service Quality attempts to concentrate on some significant factors closely related to ICSE,from the perspective of service employees.Account for Piyush Sharma’s novel view on the relationship of employees and customers in the process of ICSE,here is a review of his work.For each part of Piyush Sharma’s volume,this review gives readers a brief and concise summary,which is followed by comprehensive comments of the reviewer.This review is a good guidance and introduction for those who are interested in ICSE and those who major in foreign languages and marketing management to have a good command of Piyush Sharma’s volume.

Encounter probability analysis of typhoon and plum rain in the Taihu Lake Basin

It is of great significance to study the encounter possibility of typhoon and plum rain in the Taihu Lake Basin in order to adjust the schemes of design storm and utilize flood resource and make the decision of real-time scheduling for flood control in the Basin. Based upon the existing research findings of description of encounter phenomena of typhoon and plum rain, the initial time of typhoon affecting the Taihu Lake Basin, the start time of plum rain season and the end time of plum rain season were selected as the characteristic indices of typhoon and plum rain, respectively. According to their synchronous data from 1954 to 2009, the distribution functions of the above-mentioned three random variables were identified and a formula expressing the encounter possibility of typhoon and plum rain was derived. In view of the complexity and solution of this formula, joint distribution functions of typhoon and plum rain were constructed by the use of Gumbel Copula function on the basis of the adaptability comparison among three functions (Gumbel Copula, Clayton Copula and Frank Copula) in Archimedean functions. For the characteristics of the formula with the joint distribution functions based on Gumbel Copula function, two methods, i.e., numerical integration and Monte Carlo simulation, were selected to solve the encounter probability, and the validity of the computed results was analyzed finally.
