Dynamic P2P trust model based on context factors by Yi-chun LIU, Ying-hong LIANG

“…A multi-dimensional trust model was constructed based on the context factors.The direct trust of the interac-tive entities was estimated by integrating the time-decay factor,the transaction impact factor and the participation fre-quency.The trust similarity algorithm was designed based on the Dice similarity and the feedback credibility was aggre-gated from multiple trust chains.The direct interaction,the evaluation similarity and the trust chain was integrated for calculating the recommendation trust.The peer's trust was evaluated by combing the direct trust and the recommendation trust.A new mechanisam was proposed for the trust's update,incentive or punishment according to the peer's behavior on the interaction.The practical example analysis shows that the proposed model can effectively explain the effect of the transaction contextual factors on the entity trust,and can improve the trust sensitivity to the context transaction factors.…”

Non-invasive eye tracking technology based on corneal reflex by Di GAO, Gui-sheng YIN, Chun-guang MA

“…For the deficiencies that existing eye tracking devices are complex,have too many restrictions on the position,need to wear special equipment.A novel method of eye tracking technology using the five near-infrared light as the source of corneal reflex was put forward.This method did not need any wearing equipment,and could adapt to the natural head movement,the algorithm designed calculates the position of sight in high accuracy.A novel method of pupil edge fitting was put forward:fitted circularly and removed false points to get accurate position of pupil center,improved mapping accuracy.Used the GrayScale of image to initialize eye position quickly and accurately.Using the theory of cross-ratio invariance to make coordinate mapping,finally calculated the attention coordinate accurately.…”

Les liminalités dans les représentations du cycle solaire quotidien by Danièle Dehouve

“…The transitions of the first type are sunrise and sunset, here called anchoring zones; they correspond to the notion of “thick boundary” developed by Desclés to designate the existence of intermediate spaces between categories; those of the second type are the midday and midnight points, here called pivots because they constitute zones of exchange and shifting between the rising sun and setting sun.…”

Security signaling optimization in optical network for smart substation by Yuhao ZHAO, Xiaoguang HAO, Shaobo GENG, Peng LUO, Kun ZHOU, Jialin ZHEN, Yurong MAO

“…The communication security issue brought by smart substation is of great importance and should not be ignored in backbone optical networks.To solve this problem,firstly,the communication security challenges faced by optical networks in smart substation environment were analyzed,a signaling security optimization technique for optical networks for smart substation services was proposed.A so-called light-weighted security signaling scheme was designed to establish the end-to-end trusted connection.Under the environment of multi-domain communication services in smart substation,evaluation simulation for the signaling interaction was conducted.Simulation results show that the proposed approach can greatly enhance the security ability of multi-domain optical network with better performance in term of connection success rate.…”

The development of Anthropocene Awareness Scale. by Donghun Kang, Moon Choi

“…After a series of reliability and factor analyses, the Anthropocene Awareness Scale was optimized into a unidimensional scale comprising eight items (Cronbach's alpha = 0.88). Designed to explore individual attitudes, the scale could provide quantitative researchers with an entry point into the Anthropocene discourse and facilitate empirical studies that generate evidence for environmental policies and education in the Anthropocene.…”

Byzantine-robust federated learning over Non-IID data by Xindi MA, Qinghua LI, Qi JIANG, Zhuo MA, Sheng GAO, Youliang TIAN, Jianfeng MA

“…The malicious attacks of Byzantine nodes in federated learning was studied over the non-independent and identically distributed dataset , and a privacy protection robust gradient aggregation algorithm was proposed.A reference gradient was designed to identify “poor quality” shared gradients in model training, and the influence of heterogeneity data on Byzantine node recognition was reduced by reputation evaluation.Meanwhile, the combination of homomorphic encryption and random noise obfuscation technology was introduced to protect user privacy in the process of model training and Byzantine node recognition.Finally, through the evaluation over the real-world datasets, the simulation results show that the proposed algorithm can accurately and efficiently identify Byzantine attack nodes while protecting user privacy and has good convergence and robustness.…”

Privacy protection scheme of DBSCAN clustering based on homomorphic encryption by Chunfu JIA, Ruiqi LI, Yafei WANG

“…In order to reduce the risk of data privacy leakage in the process of outsourced clustering, a privacy protection scheme of DBSCAN clustering based on homomorphic encryption was proposed.In order to encrypt the float data in the actual scene, three data preprocessing methods for different data accuracy were given, and a policy for choosing a proper data preprocessing method based on data characteristics, accuracy and computational cost was also proposed.For the ciphertext comparison operation that was not supported by homomorphic encryption, a protocol between the client and the cloud server was designed to realize the function of ciphertext comparison.Theoretical analysis and experimental results show that the proposed scheme can ensure the security of data privacy, and has a higher clustering accuracy rate and lower time overhead.…”
