Overview and Prospect of secure communication based on Federated learning
Authors: Chen Qin , Xu Nan
Published: June 2020

With the increasing amount of data, the in-depth application guided by data prediction has ushered in the climax of development However, due to the limited depth and breadth of the data owned by each unit, the data among different units are not common, so more and more data islands are formed in the city. Data sharing has become a major obstacle to the construction of smart city. To solve the problem of data sharing, in 2016, Google first proposed the concept of Federated learning. However, the bandwidth of wireless communication has not increased significantly. As a result, the bottleneck has shifted from previous computing to today’s communication problems. During my internship in a company, I participated in a project to provide platform support for federal learning. The purpose of the platform is to facilitate the transformation of federal learning academic achievements into commercial products. Based on this project and the current situation of federal learning, this paper summarizes the secure communication problems of federal learning.

Published: June 2020

In recent years, most of Lora’s research in the field of wireless technology has focused on the experimental exploration of its stability and communication range, without much attention to the impact of the actual transmission rate. However, as the length of Lora transmission load increases, the growth rate of low-speed transmission time is faster than that of high-speed transmission time. Therefore, it means that for the transmission of large capacity packets, the lower the transmission rate, the more time it takes; the longer the time, the more power it consumes. In this paper, the SNR, RSSI and packet loss rate of Lora over 3 Kbps in urban area and mountainous area were tested and explored respectively, and the RSSI curve with distance in different environment was obtained. The test results show that the actual communication distance of Lora with high transmission rate of 21875 bps in line of sight environment can reach 3 Km, packet loss rate is less than 1%. In addition, the influence of Lora on communication quality under different occlusion degrees in a certain range was tested. In the range of 500 m to 3 km, when the occlusion ratio was 0-5%, the highest speed reference value was 21875 bps, 5-10% reference value was 6250 bps, and more than 10% reference value was 3125 bps. In this paper, Lora SX1278 transceiver was used, in the same transmission of 100 KB data, the actual transmission rate is further improved by using the maximum duty cycle and improving the request response mechanism. Compared with a Lora system for image transmission, the transmission time is reduced by 81.3% and the transmission speed is increased by 4.3 times, which greatly improves the transmission efficiency of large capacity data such as image.

Authors: Zhang Feng , Jiang Wenbao , Shi Boxuan
Published: June 2020

In the current network, there are still many security issues, such as identity fraud and address spoofing. In traditional Public Key Infrastructure(PKI), most trust models adopt a centralized trust model with a single-point trust anchor. The existing PKI system lacks a unified authentication framework and is low efficiency. Aiming at the problems of how to store public keys efficiently and how to make the network secure and trustworthy, this paper proposes a new trust anchor framework based on consortium blockchain, named Trust Anchor Chain(TAC). This study uses the form of consortium to manage TAC, proposes a hierarchical naming ID, named TAC

ID
to uniquely identify the user in TAC, and proposes a new data structure, named Struct Radix Trie, to store public key information in TAC to improve efficiency. Section 4, TAC has superiority through the comparison between local experiments and remote experiments. In TAC, users can access each other in the TAC, get the public key, and ensure the correctness of the identity. All users work together to maintain TAC to achieve equal network interconnection, security and credibility.

Authors: Jiang ZongLi , Zhang Shuo
Published: June 2020

The traditional end-to-end task-oriented dialogue models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. But in the case of large amounts of data, there are many types of questions. It performs poorly when answering multiple types of questions, memory information cannot effectively record all the sentence information of the context. In view of the above this, this article uses a modified transformer model to overcome the problems mentioned in dialogue tasks. Transformer is a model constructed using attention mechanisms, which completely discards the method of RNN (recurrent neural networks), and its structure includes two sub-parts of Encoder and decoder. It uses residual network, batch normalization, and self-attention mechanism to build the model structure, uses Positional Encoding to capture sentence information, which can speed up model training convergence and capture Longer sentence information. In this paper, we modified the activation function in the transformer and use label smoothing to optimize the training to make the model’s expressive ability better than previous.

RETRACTED: Research on Path Selection of Economic Growth Promoted by Supply-side Reform Based on Computer Simulation
Authors: Yin Xiuying
Published: June 2020

Under the current economic situation in China and the world, it is impossible to promote sustained and effective economic growth by relying solely on the demand-driven model driven by exports, investment and consumption. Supply-side reform is a new normal for economic development. It is an important decision made by the Party Central Committee in the face of weak demand and a downward trend in the economy. It has defined the strategic focus of a new round of comprehensive reform. At present, the macro-economic problems facing our country have both cyclical characteristics, but they are mainly the trend problems brought about by structural contradictions. Promoting the structural reform on the supply side is a theoretical sublimation of our country’s macro-economic environment and is also an adverse force of the current economic situation. Based on the computer simulation analysis of the connotation of supply-side reform, this paper sorts out the relevant researches on supply-side reform at home and abroad. Explains the necessity of supply-side reform in our country, and puts forward the path choice for our city to promote economic growth by supply-side reform.
Beaver-induced spatiotemporal patch dynamics affect landscape-level environmental heterogeneity
Authors: Kivinen Sonja , Nummi Petri , Kumpula Timo
Published: June 2020

Beavers (Castor sp.) are ecosystem engineers that cause significant changes to their physical environment and alter the availability of resources to other species. We studied flood dynamics created by American beaver (C. canadensis K.) in a southern boreal landscape in Finland in 1970–2018. We present for the first time, to our knowledge, a temporally continuous long-term study of beaver-induced flood disturbances starting from the appearance of beaver in the area. During the 49 years, the emergence of new sites flooded by beaver and repeated floods (61% of the sites) formed a dynamic mosaic characterized by clustered patterns of beaver sites. As beaver dispersal proceeded, connectivity of beaver sites increased significantly. The mean flood duration was approximately three years, which highlights the importance of datasets with high-temporal resolution in detecting beaver-induced disturbances. An individual site was often part of the active flood mosaic over several decades, although the duration and the number of repeated floods at different sites varied considerably. Variation of flood-inundated and post-flood phases at individual sites resulted in a cumulative number of unique patches that contribute to environmental heterogeneity in space and time. A disturbance mosaic consisting of patches differing by successional age and flood history is likely to support species richness and abundance of different taxa and facilitate whole species communities. Beavers are thus a suitable means to be used in restoration of riparian habitat due to their strong and dynamic influence on abiotic environment and its biotic consequences.
Water-food-energy challenges in India: political economy of the sugar industry
Authors: Lee Ju Young , Naylor Rosamond L , Figueroa Anjuli Jain , Gorelick Steven M
Published: June 2020

Sugar is the second largest agro-based industry in India and has a major influence on the country’s water, food, and energy security. In this paper, we use a nexus approach to assess India’s interconnected water-food-energy challenges, with a specific focus on the political economy of the sugar industry in Maharashtra, one of the country’s largest sugar producing states. Our work underscores three points. First, the governmental support of the sugar industry is likely to persist because policymakers are intricately tied to that industry. Entrenched political interests have continued policies that incentivize sugar production. As surplus sugar has been produced, the government introduced additional policies to reduce this excess and thereby protect the sugar industry. Second, although the sugar economy is important to India, sugar policies have had detrimental effects on both water and nutrition. Long-standing government support for sugarcane pricing and sales has expanded water-intensive sugarcane irrigation in low-rainfall areas in Maharashtra, which has reduced the state’s freshwater resources and restricted irrigation of more nutritious crops. Despite its poor nutritional value, empty-calorie sugar has been subsidized through the public distribution system. Third, the Indian government is now promoting sugarcane-based ethanol production. This policy has the benefit of providing greater energy security and creating a new demand for surplus sugar in the Indian market. Our analysis shows that a national biofuel policy promoting the production of ethanol from sugarcane juice versus directly from molasses may help reduce subsidized sugar for human consumption without necessarily expanding water and land use for additional production of sugarcane.

Published: June 2020

In the east Java, Brantas River is the one of the longest river. The river flows as far as 320 km with an area of 12,000 km2 across ten cities until the coast of Java sea. The potential of surface water of the Brantas river is about 12 billion m3 which is utilized by 14 million (40%) of East Java population as the main source of raw water of domistic consumption, agricultural irrigation, health, industry, electric energy, recreation, and fishery. However, since the era of 80’s, the river water condition has decreased its quality significantly. Turbidity of water in the upstream part of the river in the range of 14-18 mg/l exceeds the maximum turbidity of 5 mg/l, the pollution of mercury heavy metals at some sites reaches 0.09 mg/L or 90 times of the standard of drinking water. E-coli bacteria in water samples in the downstream region reached 64,000 bacterial/100 ml cells above the standard 1,000 bacterial/100 ml cells. The pollutions have an impact on the health quality of river banks or flood plain. About 2-4% of children aged and adolescents have cancer. Based on the observation, there are 68 schools atleast that is located at the long side of the river with the number of students more than 8000 person. They are potential generations to maintain the quality of river water in the present and future. Therefore, to cultivate their skills and awareness on the importance of maintaining water quality since 1997 was established communication network for monitoring water quality agency was named Jaring-Jaring Komunikasi Pemantau Kualitas Air (JKPKA). In the move, the agency cooperates with PT Perum Jasa Tirta I as the autonomy board of Brantas River management as the main funder. This paper aims to describe the roles of the JKPKA in involving students to monitore Brantas river water quality that has been going on 20 years more. For the involvement of students in monitoring water quality, JKPKA developed a scientific, cooperative, contextual, and constructive learning model was mentioned Water Inquiry (WI). There are five steps of the model: (1) Formation of cooperative group, (2) Field observation, (3) Data analysis and discussion, (4) Communication, and (5) Evaluation and reflection. For 20 years, since 1997-2017, JKPKA has involved more than 4300 students and 60 teachers to monitor the water quality of Brantas river with Water Inquiry method. In the future be recommended that the JKPKA can be developed into river schools for more systematic, structured, and massive movement in involving students for water quality monitoring.
