Important Significance

Mining at the fully mechanized working face below the goaf of the short-distance coal seam is influenced by the upper goaf. To address this problem, methods such as theoretical analyses, numerical simulation, and on-site measurement are used to study the strata behavior characteristics of the Ningxia Lingxin Coal Mine 051508 working face in this study. The roof weighting intervals of the working faces below the goaf and the non-goaf are obtained via theoretical calculations. The stoping processes of the working faces below the goaf and the non-goaf are simulated with FLAC3D to obtain the distribution law of the bearing pressure and plastic zones before the working face. Based on the statistical analysis of the measured working resistance of the supports and its distribution, the roof weighting interval of the working face mining below the goaf is obtained. The results show that the roof weighting interval and the advanced abutment pressure during mining at the working face below the goaf are smaller than those below the non-goaf, providing a reasonable theoretical basis for mining below the goaf, and having important significance for safe and efficient mining.

Behavior Characteristics

Behavioral characteristic is one of the important targets in conceptual design and re-design of electromechanical products. To summarize the knowledge of behavior characteristics of electromechanical products, this paper proposed the concepts of behavioral effect, elemental behavior and behavioral chain. It made the modification to classical Petri nets, then analyzed and expressed the behavior characteristics using the modified Petri nets. Finally, a case study of an electric nail-gun was conducted to demonstrate the feasibility of the proposed methodologies.

Installation and maintenance of flow gauging stations to assess wastewater dilution in small creeks is expensive. The method outlined in this paper provides a flexible and cheap alternative for situations with dilution factors smaller than 10 and unambiguous flow direction. It is shown that conductivity profiles from three sampling locations enable accurate identification of the dilution factor with an uncertainty of ±10–30%. Furthermore, much insight can be gained on the temporal behavior of both, the receiving water and the wastewater treatment system by combined analysis of conductivity and temperature data. In this case study the data also enabled identification and tracking down of illegal polluters.

Significant Data

New media is essential part of everyday practices of individuals. Research shows that 80% respondents on the territory of Serbia checks their social media accounts several times a day. For average consumer this means that they are in constant contact with friends and that they have easy access to information and news. For companies continuous presence is a source of significant data about habits and opinions of consumers. Question remains: How can users create their own digital footprints in various ways? How big companies can abuse data? If data became oil of 21st century, does that mean users have become commodities? The aim of this paper is to show what is happening with users' privacy when engaging with new media, through mapping characteristics of new media, current centers of power in digital world, defining the concepts of digital footprints and privacy in online sphere and through case study of privacy violations.

Abstract. Simultaneous co-located microbarometer and vertical-pendulum seismometer measurements at St. Petersburg (59.9° N, 29.8° E) with total duration of 4 months are used to study atmospheric oscillations at steady frequencies at periods shorter than 8 h. The temporal behavior of the phase shift between oscillations detected simultaneously by both instruments is analyzed for oscillations of periods up to as short as ~0.5 h. Some of oscillations last up to several days. For the 42–90 min and 2.5–5 h period ranges, the temporal behavior of the power spectra are considered and correlated with the atmospheric angular momentum of zonal wind, tropical cyclones and large earthquakes. Signatures of sequences of subharmonics of the solar tide are revealed with periods up to day/30. There are indications of effects of the 5-day planetary waves and tropical cyclones on wave activity in the ~1–5 h period range. A weak increase of wave activity is observed when large earthquakes occur.

This study is aimed 1. to examine cultural destinations attribute, 2. to examine factor of tourist travel behavior characteristics and 3. to develop tourist satisfaction in Saung Angklung Udjo Bandung.The sampling using an incidental technique with the number of respondents as many as 400 tourists. The variables used, first is tourist satisfaction as a dependent variable, and the independent's variables are cultural destination attribute and tourist travel behavior characteristic. The correlational analysis, multiple linear regression analysis and multivariate analysis of variance are conducted to analyze this research.The cultural destination attribute has positive effects on tourists satisfaction and significant differences between experience visit Saung Angklung Udjo for interest re-visit Saung Angklung Udjo as the cultural destination with overall respondents’ satisfaction.From this research, researchers can add the knowledge and experience related tourist satisfaction, and it is also expected that the researcher in practice can use the existing theories in this study. Otherwise, cultural destination especially Saung Angklung Udjo in Bandung, West Java, Indonesia get more knowledge regarding tourist satisfaction, from that satisfaction can help administrators and marketers to more understand customers and ensure their want are fully meet. For the readers: The result of this research can be used as a reference and can be useful for scientific documentation for the readers. This research also helps for readers increase the knowledge and insight visitor's satisfaction with experience cultural tourism especially SaungAngklungUdjo, Bandung, West Java.There are some limitations of research: 1. The research period used in this study relative short and 2. Most of the tourist in Saung Angklung Udjo is a student under 15 years old.Considering the high development of tourism in Indonesia, especially in the field of cultural destination, bringing many marketers who preserve the culture in Indonesia, one of them Saung Angklung Udjo. The owner of a tourist destination to have knowledge about the importance of promoting a culture that they provide to tourists, they should know the destination attributes and tourist satisfaction, they also should know the effect both of that case. Thus, on the basis of these researchers conducted the study by taking the title“Analysis cultural destination attribute and tourist travel behavior characteristics on tourist satisfaction: A case Saung Angklung Udjo, Bandung, West Java, Indonesia”.
