Limacon gear, which is put forward as a new non-circular gear recent year, is used in the various equpiments. In order to analyse the transmission characteristics of limacon gear, three-dimensional models of one-order and high-order limacon gear were established according to its basic meshing theory,...

A billboard is a large board that shows advertisements. In China, billboard management relates to several government departments. The inspection staff must records status of specific billboards and compares the status with register information manually. This paper proposes a novel RFID-based billboard...

There is the vague boundary between fault omen and fault phenomenon of aviation equipment, one Fuzzy C-means (FCM) cluster method is given to divide the fault classification, which provide some help to determine the next fault mode.

The self-propelled Aerial Work Platforms (SAWP) will go through the rough road, therefore, the oscillating mechanism should be mounted on the chassis in order to adapt to safe and comfortable operation of the SAWP. When the boom of the SAWP need to be rotated by 360° continuously, the stability of the...

There is the problem that Rough Set Theory cannot process the quantitative data in the equipment test data. One FCM method is given to discretize the quantitative data, and the center value of the each cluster is calculated in order to discretize. And then, the attribution reduction algorithm and rules...

There are the problem that it must be given the reference standard sequence ahead according to the experience or statistics method in the classical grey entropy relation for fault diagnosis. But it is often lack of objectivity and high accuracy degree. The paper introduced one advanced Fuzzy C-Mean cluster...

In the dynamic process of warship combat system alignment, the data of shipboard radar measurement at sea calibration object contains outliers with trend item, it can not simply be excluded based on some statistical algorithms. In this paper, an outliers excluding algorithm was proposed based on wavelet...

This study investigates three factors of the acceleration equation, i.e., acceleration constants c1 and c2 and inertia weight w, which are then used as events in particle swarm optimization for parameter optimization in the para-tank model (PTM) during rainfall–runoff simulation. The values of 0.2, 0.5,...

The purpose of this article is the evaluation of the actual condition of unmanned underwater vehicles in the world. The extensive review of the world market of unmanned underwater vehicles was made. The all reviewed vehicles are used at present time or exist like prototypes. All robots were systematized...

To increase the production of hydrocarbons Russia stepped on the shelf of the Arctic seas. The Arctic, as it is known, is characterized by severe climatic conditions, it can be attributed to the extremely long frosty winter, strong winds, six-month polar nights and ice on the surface of the sea all year...

This work is devoted to creation of transport and manipulation robotic system (TMS) to work on the surface of the spacecraft. Undoubtedly, the TMS is a powerful tool in solving problems of the study of space, so it is evident that the role of space robotics is continuously increasing due to the need...

In this paper, the route-based fuzzy adaptive control strategy(RFACS) of PHEV is designed based on the Intelligent Transportation System ITS . Through the ITS to get the speed characteristic of the future path and the fuzzy intelligent control, the RFACS strategy can improve the efficiency of PHEV system...

The posture of the bridge girder plays a very important role for the safety and efficiency of the bridge construction. This paper mainly proposed a mathematical method for determining the position and orientation of bridge girder and distributed Incremental Launching devices. Firstly, the background...

In order to reduce the equipment failure frequency and maintenance cost, equipment failure must be effectively predicted. Consider that the actual failure interval of equipments is to contribute to maintenance planning and scheduling, it is used to statistical analysis the failure trend. According to...

The paper considers the main criteria for establishing advanced unified standard series of mechanical transmissions. It presents the development of the entire standard series of advanced manual transmission with automatic control with a number of gears from 6 to 16. It considers features of structures...

The purpose of this study is to identify the different strategies employed by micro- enterprises supporting by the government funding with different developmental stage of industrial life cycles. This paper used a multiple-cases study method and selected 48 cases micro-enterprises to analyze the developmental...
