Abstract Through the combination subject of scientific research, the design method of the winch driven by contactless magnetic coupling is researched for the core purpose of the turning shaft sealing in a deepwater environment. This method has six design phases, including domestic and foreign information query and retrieval, graphic analyses of relevant structures, innovative design of 2D assembly sketches, a theoretical computation of structure parameters, the 3D modeling and motion simulation and engineering drawing. This method is of generality, which can provide examples for the postgraduate students and engineering personnel in self-renovation design of scientific research.

Exploration of deep-rock mechanics has a significant influence on the techniques of mining and rock mechanics. Rock coring technique is the basic method for all rock mechanics study. With the increase of the drilling depth and increasing strength of the hard rock, how to obtain high-quality rock core through various coring techniques is an eternal work. Here an innovative method is applied to design the new coring system to maximize the efficiency of operation. The stress conditions or parameters of rock core in the coring are analyzed, and the mechanism of the core with in situ stress is shown in this paper. The conflict of the core and coring tool chamber is proposed for the innovative design. The innovative design method is fulfilled by the theory of inventive problem solving (TRIZ). An improved coring system for the full-length core with in situ stress was obtained with the solutions of improved coring mechanism, cutting mechanism, and spiral drill pipe.

In order to improve the shortcomings of the existing machine, a new laser pipe-blanking machining is designed. A 3D optimization designing method of pipe-blanking machine is presented through using Solidworks software as a design platform. The simulation and verification of design results is realized by the virtual assembly of whole machine, interference checking and motion simulation of machining process. On the basis of the analysis of simulation results, the structure and capability of the product is further analyzed and optimized in order to achieve the best design.

The Geneva mechanism has been widely used in various kinds of machinery. This thesis is about the geneva mechanism of the automatically rotate workbench, using the SolidWorks 3D modeling software to establish a model of the geneva mechanisms parametric design. Afterwards, to motion simulate the geneva mechanism by the Motion, then output the those parameters. In the end, its angular velocity and the angular acceleration, as well as the motion of the interval time will be calculated with the driving plate twirling in a constant speed. The result provides a theoretical foundation for the structural design and the engineering application of the design of this institution. It also present a method for improving the design.

The Right

Children are the future successors of the nation who must be equipped with supporting knowledge and education. One of the factors that influence the development of children are children’s creativity. Creativity is important for children because creativity is useful as a human need to be creative, creativity allows children to express themselves and thoughts in solving problem and many more. Creativity activities in schools are limited, namely 4-5 hours due to strict curriculum (Kemendikbud, 2012). The facilities that support the development of children's creativity in Pontianak is quite limited. This condition shows that Pontianak needs facilities that support the development of children's creativity, namely the Child Creativity Center in Pontianak. The design method starts from identifying the problem by looking at the issues, data collecting consists of primary data and secondary data, and then the data is analyzed which produced pre design drawing. The emphasis on the design is child-friendly which includes aspects of safety, comfort, freedom and stimulates children's potential. This concept produces a mass building design with a circular shape that has been transformed. The use of the right colors, shapes, materials and dimensions is the core of the design of the Children's Creativity Center in Pontianak.

Core Idea

The core idea of metric-based few-shot image classification is to directly measure the relations between query images and support classes to learn transferable feature embeddings. Previous work mainly focuses on image-level feature representations, which actually cannot effectively estimate a class's distribution due to the scarcity of samples. Some recent work shows that local descriptor based representations can achieve richer representations than image-level based representations. However, such works are still based on a less effective instance-level metric, especially a symmetric metric, to measure the relation between a query image and a support class. Given the natural asymmetric relation between a query image and a support class, we argue that an asymmetric measure is more suitable for metric-based few-shot learning. To that end, we propose a novel Asymmetric Distribution Measure (ADM) network for few-shot learning by calculating a joint local and global asymmetric measure between two multivariate local distributions of a query and a class. Moreover, a task-aware Contrastive Measure Strategy (CMS) is proposed to further enhance the measure function. On popular miniImageNet and tieredImageNet, ADM can achieve the state-of-the-art results, validating our innovative design of asymmetric distribution measures for few-shot learning.

This chapter introduces the core thematic ideas of the present volume: that psychiatric research is in crisis, that it has entered a period of extraordinary science, and that a fully adequate response to the crisis should be responsive to the perspectives and interests of persons. We identify various sources of the crisis, drawing special attention to controversies concerning the role of the DSM in psychiatric research. And, we identify different strategies of response to the current crisis, including approaches that emphasize the importance of personal perspectives and the needs of the clinic and those that emphasize the important role of various scientific research programs. Further, we survey various developments (e.g., debates over fundamentals and a role for philosophical analysis, probing of the problems of the DSM framework, relaxation of standard forms of research practice, the introduction of the Research Domain Criteria initiative and other novel research programs) that are jointly suggestive of Thomas Kuhn’s characterization of periods of crisis that can arise in scientific research and of the “extraordinary science” that ensues. We suggest that this Kuhnian framework is useful for understanding the state of psychiatric research and it provides a framework for thinking about responses to the current crisis. We conclude with brief overviews of the contributions to the volume, each of which provides such a response.

Taking the compound gear trains as an example, the principle of the transmission mechanism was analyzed, and the rotational speed of the key gears in the compound gear trains was calculated by using the calculation formula of transmission ratio to obtain the simulation parameters of UG movement. The gear tool box in UG was applied to complete the modeling and meshing assembly of the bevel gear and spur gear, the rotation pair and gear pair was to motion simulation, the gear transmission state could have visually observed by motion simulation, and then the chart was analyzed to verify the design rationality of the gear train.
