Association rules recommendation algorithm supporting recommendation nonempty by Ming HE, Wei-shi LIU, Jiang ZHANG

“…Existing association rule recommendation technologies were focus on extraction efficiency of association rule in data mining.However,it lacked consideration of recommendation balance between popular and unusual data and efficient processing.In order to improve the quality and efficiency of personalized recommendation and balance the recommendation weight of cold and hot data,the problem of mining frequent itemset based on association rule was revaluated and analyzed,a new evaluation metric called recommendation RecNon and a notion of k-pre association rule were defined,and the pruning strategy based on k-pre frequent itemset was designed.Moreover,an association rule mining algorithm based on the idea was proposed,which optimized the Apriori algorithm and was suitable for different evaluation criteria,reduced the time complexity of mining frequent itemset.The theoretic analysis and experiment results on the algorithm show that the method improved the efficiency of data mining and has higher RecNon,F-measure and precision of recommendation,and efficiently balance the recommendation weight of cold data and popular one.…”

Secure D2D underlaying cellular communication based on artificial noise assisted by Xiao-lei KANG, Xin-sheng JI, Kai-zhi HUANG

“…A secure communication scheme based on artificial noise assisted from base station(BS)was proposed to improve the system secrecy rate of the D2D underlaying cellular.Firstly,the system secrecy rate was modeled.Then the BS with multi-antennas added artificial noise(AN)in cellular user’s signal as well as designed beam vectors of the desired signal and artificial noise to maximize system secrecy rate.In the end,a joint optimization scheme based on the fairness constraint was introduced to optimize beam vectors of the desired signal,the power allocation for BS’s information signal and AN and the D2D power control.Simulation results show that the system ergodic secrecy rate can be improved 2.7 bit·s⁻¹·Hz⁻¹more than the schemes based on SVD and zero-forcing at most.…”

Valutare, progettare, implementare. I percorsi punitivo-rieducativi del sistema penale minorile tra giustizia riparativa e terzo settore by Fabio Ricciardi

“…Hence the proliferation of re-educational (stay in the community, probation for social service, criminal mediation). These tools, designed with the aim of combining the punitive aspect with that of subjective repentance, try to carry on the implementation of personal skills, remaining in the balance between the need to guarantee the expiation of the sentence and that of producing new subjectivities, able to free themselves from conditions of social marginality as long as the characteristics suitable for inclusion in the productive system are acquired.…”

Asynchronous perception algorithm based on energy detection by Pan YU, Bin LI, Cheng-lin ZHAO

“…In the future heterogeneous wireless networks,since primary user (PU) and cognitive secondary user (SU) are not coordinated to be synchronous,it will result in sense timing difference between PU’s transmitter and SU’s receiver.For this asynchronous sense case,a new asynchronous sensing algorithm based on Bayesian estimation theory was proposed.A unified dynamic state space model was first proposed to describe the observable energy relationship with dynamic PU state and unknown timing difference.Then,an iterative estimation scheme was designed using stochastic finite set and the rules of maximum posterior probability.Finally,approximated estimation results were obtained by using a particle filter.The simulation results show that the proposed asynchronous scheme significantly eliminates the uncertainty of the received signal information and thus improves the spectrum sensing performance by obtaining the time difference accurately.…”

Data management based on blockchain and edge computing for Internet of things by Guanjie CHENG, Zhengjie HUANG, Shuiguang DENG

“…The popularity of smart devices has driven the development of the application of Internet of things (IoT) technology,and the resulting massive amount of IoT data has brought challenges to traditional centralized data management methods,such as performance,privacy,and security.Therefore,a data management framework of IoT based on blockchain and edge computing was proposed to support the distributed IoT data management.The distributed storage and access control could be provided by the framework for the IoT data.At the same time,a set of the built-in encryption scheme was designed to protect the data security and privacy and safeguard the data ownership.By introducing edge computing,the scalability bottleneck of the blockchain the system was relieved.The processes of data storage and data access based on this framework were given,and the algorithm of the system implementation based on the smart contract technology was explained in detail.Experiments show that the IoT data management system based on this framework outperforms the traditional cloud-based data management systems.…”

Decision-aided-based multiple blind PN code estimation algorithm of asynchronous CDMA signal by Zhaoyang QIU, Tianyun LI, Xiangming CHEN

“…Aiming at the problem of blind estimation of multi-user pseudo-code of multi-path asynchronous code division multiple access (CDMA) signal,using the finite element (FA) characteristic of transmitted symbol,a decision aid (DA) method based on maximum likelihood was proposed.A two-step iterative estimation structure for PN code,transmitted bit and channel was designed to realize the estimation of multiple user code in asynchronous CDMA system with superior performance.Moreover,the Cramer-Rao bound (CRB) of PN code estimation in asynchronous CDMA signal was derived to evaluate the performance of proposed method.Simulation indicates significant improvement in performance which is close to the theory bound of the proposed method compared to commonly-used iterative least square with projection (ILSP) method.The method can also achieve superior estimation when the user number increases.…”
