Flow experience can promote person to produce an important aspect of happiness. A lot of study on flow experience can give a person with great pleasure and improve the quality of individual life. Physical exercise on negative psychological improvement has received a lot of empirical support, the rise of positive psychology, puts forward a new thinking for physical exercise, ...

With the development of city, all kinds of vehicles, especially private cars which are dramatically increased, traffic problems become more and more serious than ever before. In recent years, all kinds of efforts has been made to reveal the structure features of public transit system. Some basic structure features in transit network, for example, the analysis of statistic ...

Promoting the construction of the Belt and Road is a major initiative of China's opening up to the outside world at a new stage of economic development, which is of great significance to both China and the countries along the Belt and Road. Taking investment projects along the Belt and Road as an example, this paper explains the current situation of investment projects along the ...

For environmental purposes, namely resource conservation, it is proposed to install a rainwater gathering system. You can collect rainwater by means of the system and use this water for the needs of the trolley fleet (washing of rolling stock). This system reservoirs can be also used for storage of excess filtered water.

In order to solve the problem of accurate navigation of mobile robots in dynamic indoor environment, a semi-direct RGB-D visual SLAM (Simultaneous Localization and Mapping) algorithm based on motion detection algorithm is proposed. The algorithm is mainly divided into three parts: motion detection, camera positioning and dense map construction based on TSDF (Truncated Signature ...

The composition of the glass scintillation materials was elaborated. The effects of rare earth ions upon spectral and luminescent properties of the glasses and glass ceramics were established.

Technology is the key to unlocking human growth. Looking at the history of human economic growth over 200 years, from the steam engine to the invention of electricity to today's information technology, every major general technological change has brought about the re-optimization of resource allocation and continued economic prosperity. At present, the world is opening a new ...

The study of the rheological properties of aqueous solutions of starch blends with sodium alginate and agar-agar as well as the physico-mechanical properties of bicomponent films on their basis has been carried out. The extreme behavior of polymer blends with low content of one of the polymers is described in terms of mutual solubility or thermodynamic compatibility. There is a ...

To avoid stick-slip vibration, one of the most important forms of self-excited vibrations in deep hole drilling, this paper studies the stability a drill system based on a twodegree-of-freedom discrete model. It is a state-dependent delay model that could describe the nonlinear dynamic characteristic of drilling systems more accurately, compared with the traditional constant delay ...

Mn16Fe16CoxNi34-xGe7Si27（x=1，3，6，7.5，9）series alloy were prepared by vacuum arc melting technology under the protection of argon flow and structure and magnetocaloric effects of MnCoGe-FeNiSi composite material was investigated . Using X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) method, structure and magnetocaloric effects of the alloys were analyzed, respectively. ...
