Survey on differential privacy and its progress by Zhi-qiang GAO, Yu-tao WANG

“…With the arrival of the era of big data sharing,data privacy protection issues will be highlighted.Since its introduction in 2006,differential privacy technology has been widely researched in data mining and data publishing.In recent years,Google,Apple and other companies have introduced differential privacy technology into the latest products,and differential privacy technology has become the focus of academia and industry again.Firstly,the traditional centralized model of differential privacy was summarized,from the perspective of analysis of data mining and data released in the differential privacy way.Then the latest local differential privacy regarding data collection and data analysis based on the local model was described,involving crowdsourcing with random response technology,BloomFilter,statistical inference techniques.Finally,the main problems and solutions of differential privacy technology were summarized.…”

Efficient parallel MAP timing recovery algorithm for TDS-OFDM systems by Yangguang LI, Jianrong BAO, Bin JIANG, Chao LIU

“…According to the problems of the existing timing recovery algorithm with the time-domain orthogonal frequency division multiplexing (TDS-OFDM) modulation in the wireless multimedia transmissions of 5G communications,such as slow processing speed and big theoretical distance,a parallel MAP timing recovery algorithm was proposed.Specifically,the Lagrangian interpolation was used and the amplitude and polarity change of the optimal sampling points were extracted to detect the timing error efficiently.Meanwhile,with the parallel maximum a posteriori (MAP) criterion,the timing error estimate was obtained at high speed.The simulation results show that the accuracy of the proposed algorithm is improved,when comparing with the existing MM algorithm,Gardner algorithm and others.The estimation result is very close to the MAP timing recovery algorithm,the difference is about 2 dB.…”

Study on the application of IGSO into mobile satellite communication by ZHANG Geng-xin1, LI Su-dan2, GAN Zhong-min1

“…The related coverage performance,Doppler shift and service-supporting capability of the IGSO constellation was studied for the given area.The results show that,the constellation,which consists of two or three IGSO satellites,can achieve good coverage characteristics（the percent of time of one and more satellites coverage and average elevation an-gle）to the Chinese and nearby area with small Doppler shift.The link budget shows that,adopting IGSO can effectively solve the low elevation angle problem faced by GEO satellite,and similar performance,which can only be implemented by a very big GEO satellite,can be achieved by two or three relatively small IGSO satellites.So the solution of adopting IGSO to provide mobile satellite communication system is technically feasible.…”

Research development and forecast of automatic speech recognition technologies by Haikun WANG, Jia PAN, Cong LIU

“…The purpose of automatic speech recognition (ASR) is to make the machine to be able to “understand” the human speech and transform it to readable text information.ASR is one of the key technologies of human machine interaction and also a hot research domain for a long time.In recent years,due to the application of deep neural networks,the use of big data and the popularity of cloud computing,ASR has made great progress and break through the threshold of application in many industries.More and more products with ASR have entered people’s daily life,such as Apple’s Siri,Amazon’s Alexa,IFLYTEK speech input method and Dingdong intelligent speaker and so on.The development status and key breakthrough technologies in recent years were introduced.Also,a forecast of ASR technologies’ trend of development was given.…”

The role of ethnoscience in the build-up of ethnoconservation as a new approach to nature conservation in the tropics by Antonio Carlos Diegues

“…This paper aims to describe the main features of a new approach in nature conservation in the Tropics and to analyse the important role of ethnoscience in this process, taking Brazil as a case study.It begins with a critique of the hegemonic model for nature conservation in which traditional communities living in the areas transformed into non-use protected areas have been displaced or too severely hindered to continue with their traditional way of life based on small-scale agriculture, fishing, forest harvesting and hunting. The role of big international conservation NGOs in spreading this hegemonic approach in developing countries is also analysed.This model is being set-up in many tropical countries. …”
