Influence of Internal Quality of Gear on Strength and Life of Gear by Xiaolu Zhu

“…The influence of some items of internal quality of carburizing quenching gear （surface decarburization， internal oxidation， coarse martensite， carbide structure， non-martensite structure， black structure， retained austenite， grain size， etc.） on gear strength and life are mainly discussed， the degree of influence is mostly expressed by the data of experimental results. Finally， the <italic>R-S-N</italic> curve test data（gear decarburization layer depth 0.2~0.3 mm， the bending endurance limit stress <italic>σ_F</italic>_lim at tooth root is reduced by 23%~50%） of carburizing and quenching gears with 5 materials show that the great influence of gear surface decarburization on gear bending fatigue strength.…”

A joint optimization algorithm based on energy efficiency maximization for massive MIMO systems by Haiyan CAO, Ruirui FENG, Xin FANG, Xiumin WANG, Fangmin XU

“…For the massive multi-cell multi-input multiple-output (MIMO) communication uplink system with unknown channel status information,a resource allocation algorithm which jointly optimizes the pilot sequence length,pilot symbol power and data symbol power was proposed.With the maximum ratio combining (MRC) receiver,the influence of circuit power was considered,pilot contamination and the constraint of maximum transmission power,and a nonconvex function modeled with the goal of maximizing energy efficiency (EE) was established.Firstly,the fractional form was transformed into an equivalent subtractive form by using the properties of fractional programming and then decomposed into a series of DC problems,finally,by using an iterative optimization algorithm,the three variables were alternately adjusted with maximizing the energy efficiency.Simulation results show that with the increasing of the maximum symbol transmission power,the proposed scheme can still have the great EE performance for the massive MIMO systems.…”

Certificate-based cross-domain authentication scheme with anonymity by Yongshan DING, Lixin LI, Zuohui LI

“…Considered the cross-domain authentication of mobile devices in the Internet of things,a certificate based anonymous cross-domain authentication scheme was proposed.First,combined with the characteristics of PKI and IBS,a certificate based signature (CBS) algorithm was proposed，and the security of the proposed CBS scheme was proved.The verification result of the signature in the algorithm was constant,which ensured the anonymity of the authentication entities in the cross-domain process.The algorithm does not contain pairing,and avoids complex certificate management in traditional PKI and the key escrow and distribution of IBS.Then a cross-domain authentication scheme for mobile devices was constructed by combining the proposed signature algorithm.The scheme ensures the anonymity of authentication at the same time.Finally,compared with other schemes,the scheme proposed is more secure and has less computation cost and communication cost.Moreover,the scheme is simple and efficient,and could be applied to the cross-domain authentication of mobile devices.…”

Joint design of tuple space and bitmap for two-dimensional packet classification by XIE Kun, ZHAO Jiao-jiao, ZHANG Da-fang

“…Based on dimension decomposition idea,a high-performance two-dimensional packet classification algorithm by jointing tuple space and bitmap technology,called TB,was designed and implemented.Firstly,TB processes one-dimension matching for SIP and DIP respectively,then it forms tuple space access route by applying the cross-combination method to the matching results in the first step,finally,to reduce the number of required accessing tuple space,TB obtains the multi-dimensional matched rule by adapting bitmap filtering technique to filter tuple space.Compared to traditional tuple space algorithm,the structure of TB is clearer,more concise and easier to update and implement,TB also has better time and space performance.The experimental results show that TB algorithm saves 35.1% of the space requirement than RSFR algorithm and the number of average memory accesses lower than RSFR 26.6%.…”
