Order of Dirichlet Series in the Whole Plane and Remainder Estimation

In this paper, firstly, the p order and pz order of Dirichlet series which converges in the whole plane are studied. Secondly, the equivalence relation between remainder logarithm In En-1 （f, α）, In Rn（f, α） and coefficients logarithm In ｜an｜ is discussed respectively. Finally, the theory of applying remainder to estimate ρorder and ρβ order can be obtained by using the equivalence relation.

A Review in the Core Technologies of 5G: Device-to-Device Communication, Multi-Access Edge Computing and Network Function Virtualization

5G is a new generation of mobile networking that aims to achieve unparalleled speed and performance. To accomplish this, three technologies, Device-to-Device communication (D2D), multi-access edge computing (MEC) and network function virtualization (NFV) with ClickOS, have been a significant part of 5G, and this paper mainly discusses them. D2D enables direct communication between devices without the relay of base station. In 5G, a two-tier cellular network composed of traditional cellular network system and D2D is an efficient method for realizing high-speed communication. MEC unloads work from end devices and clouds platforms to widespread nodes, and connects the nodes together with outside devices and third-party providers, in order to diminish the overloading effect on any device caused by enormous applications and improve users’ quality of experience (QoE). There is also a NFV method in order to fulfill the 5G requirements. In this part, an optimized virtual machine for middle-boxes named ClickOS is introduced, and it is evaluated in several aspects. Some middle boxes are being implemented in the ClickOS and proved to have outstanding performances.

Some biostratigraphically important palynomorphs from Paleocene Minato Formation,Iwate Prefecture,Northeast Japan

Palynological study of the Minato Formation, Noda Group, distributed in the vicinity of Kuji City, Iwate Prefecture, Japan is discussed in this paper. Biostratigraphically important palynomorphs including four angiosperm species, Triprojectus subspinulosus(Funkhouser) Braman, Triprojectus cf. spinulosus(Mtchedlishvili) Stanley, Paraalnipollenites confusus Hills et Wallace and Pistillipollenites macgregorii Rouse, and one fungi species, Pesavis tagluensis Elsik et Jansonius are described. Palyno-assembleges from the lower and the middle horizons of the Minato Formation are considered to indicate Danian in age, which corresponds well with the known fission-track dating. Palyno-assembleges from the lower and middle horizons of the Minato Formations are correlative with those from the Wuyun Formation and the Upper Tsagayan Subformation of Heilongjiang(Amur) River area in northeast China and the Russian Far East. Despite the similarity of the palyno-assembleges, differences in the diversity of angiosperms and species composition of some biostratigraphically important species are recognized between the two regions.

Obstacle Avoidance Gloves for the Blind Based on Ultrasonic Sensor

Ranging based on the reflection principle of ultrasonic wave propagating in the air has been widely used in modern life, such as car reversing radar, robot automatic obstacle avoidance etc. Aiming at the situation that the blinds have no way to know whether there are obstacles or big safety risks in front of them when they are walking, this paper designed obstacle avoidance gloves for the blinds based on ultrasonic sensors. With Arduino Nano single chip microcomputer as main controller, combined with ultrasonic sensor module, bluetooth module and speaker module, the glove realized the function of obstacle detection and alarm. The main working principle is by using the ultrasonic sensors to transmit and receive ultrasonic, the time difference for transmitting and receiving to detect the distance of obstacles ahead. Besides, by means of voice module output audio signals with different frequency according to the obstacle distance, the blinds can judge the distance between them to the obstacles based on the sound with different frequencies they heard. In this way, they can make responses in advance to avoid the obstacles ahead and the happening of the risk.

Expression and Application of Fairy Tale Elements in Experiential Agricultural Garden:A Case Study of Ji'an Shiyang Fairy Tale Garden

After more than 30 years of development,leisure agriculture has developed rapidly as a new star of China's emerging industries.With the upsurge of the nostalgic market and the parent-child market,the application of fairy tale elements in the experiential agricultural garden has enhanced the product competitiveness of the experiential agricultural garden.Through the application and expression of the material elements,spiritual elements and emotional elements in the fairy tales in the experiential agricultural garden,the fairy tales are expressed by reality,and the reality is beautiful by fairy tales.The fairy tale elements are used to increase the vitality of the agricultural park,and the good medicine in childhood is used to cure the"sequelae of stress",relieve the mental stress that people in the city cannot relieve,and regain fun dreams of childhood.Taking the planning of Ji an Shiyang Fairy Tale Garden as an example,the expression and application of fairy tale elements in the experiential agricultural garden are explored,and the expression of material,spiritual and emotional elements in the fairy tale is expounded from the planning level,design level and scheme level.
