Virtual environments, however, tend not to make this information available. The sparse number of applications that present additional information furthermore tend to limit their scope to pure construction information and do not incorporate information from loosely related knowledge domains, such as cultural heritage or architectural history information. We therefore started an investigation of two of the newest developments in these domains, namely game engine technology and semantic web technology. This paper documents part of this research, containing a review and comparison of the most prominent game engines and documenting our architectural semantic web. A short test-case illustrates how both can be combined to enhance information visualization for architectural design and construction.展开更多

The system was developed by integrating Web-GIS (Geographic Information Systems), SNS (Social Networking Services) as well as the recommendation system into a single system. The system used the non-language information such as signs, marks and pictograms in addition to English information, and displayed sightseeing spot information and conduct navigation on 2D and 3D digital maps of the Web-GIS. Additionally, the system was operated for two weeks in the central part of Yokohama city in Kanagawa Prefecture, Japan, and the total number of users was 54. Based on the results of the web questionnaire survey, all of the specific functions are highly evaluated, and the usefulness of the system when sightseeing was excellent. From the results of the access analysis of users' log data, it is evident that it can be said that the system was mainly used before sightseeing and users confirm their favorite sightseeing spots and made their tour planning in advance, using 2D and 3D digital maps.展开更多

Now the term "Ecotourism" is almost applied to all tourism activities which are based on nature. Faced to the flooding of those unqualified Ecotourism, it is of great necessity to put forward professional claim. The present writer holds that the key to the realization of rigorous Ecotourism chiefly lies in the relationships among the different interest groups involved in it. So the focus of this paper is just on giving a special analysis to the interest relations between those stakeholders which include local government, tour-operators, local residents and eco-tourists, and thus helping to find out what wrong is in those unqualified Ecotourism and the roots of those problems.展开更多

This investigation initially emphasized the importance of the marketing for the organizations, mainly the orientation for the market. After a brief explanation on the hotel segment in Portugal, an empirical study was presented, of quantitative, exploratory and traversal character, performed with the largest groups of 20 hotels of Portugal, using as an instrument of collection data, the traditional Markor scale (market orientation) adapted to the hotel sector. After analyzing the data, it was found in the investigated organizations that a good capacity to generate market information and response to the market, which formed two of the three constructs of Markor scale. However the results obtained with the construct of the dissemination of market information were below the expectations. It was possible to conclude that marketing professionals of the large hotel groups in Portugal are well oriented to the market, something not shared by other investigated departments of the hotels. So the current challenge for the main networks of hotels in Portugal is to improve the internal dissemination of information that marketing professionals gathered at the market.展开更多

The work included a combination of GIS technology, adoption of the differentiation index D, and the multi-group differentiation-measure model D(m). The results provided a basis for the following conclusions: 1) From 1988 to 2012, the degree of differentiation of the rural residential land first decreased, and then increased. The general residential, commercial residential and garden-house land-types all showed declining trends, of which the garden-house type presented the most intense volatility. 2) The overall background of the traditional residential land type was gradually replaced by a new residential land type, and the total area of residential land increased year by year, significantly improving the overall residential conditions. The areas of the new residential land type showed growth, and were increasingly widely distributed in the coastal tourist resorts, transportation corridors, and scenic areas. 3) Government policy, social differentiation, market mechanisms, and individual choices(along with other factors) were mutually promoted, although still restrained. However, all of these factors interacted to constrain the developmental direction and the processes affecting tourism real estate in the Dalian Jinshitan Tourist Resort.展开更多

It requires players to make predictions, starting from first order uninformative predictive distribution functions (or conjectures) and keep updating with statistical decision theoretic and game theoretic reasoning until a convergence of conjectures is achieved. Information known by the players such as the reaction functions are thereby incorporated into their higher order conjectures and help to determine the convergent conjectures and the equilibrium. In a BEIC, conjectures are consistent with the equilibrium or equilibriums they supported and so rationality is achieved for actions, strategies and conjectures. The BEIC approach is capable of analyzing a larger set of games than current Nash Equilibrium based games theory, including games with inaccurate observations, games with unstable equilibrium and games with double or multiple sided incomplete information games. On the other hand, for the set of games analyzed by the current games theory, it generates far lesser equilibriums and normally generates only a unique equilibrium. It treats games with complete and perfect information as special cases of games with incomplete information and noisy observation whereby the variance of the prior distribution function on type and the variance of the observation noise term tend to zero. Consequently, there is the issue of indeterminacy in statistical inference and decision making in these games as the equilibrium solution depends on which variances tends to zero first. It therefore identifies equilibriums in these games that have so far eluded the classical theory of games. Finally, it also resolves inconsistencies in equilibrium results by different solution concepts in current games theory such as that between Nash Equilibrium and iterative elimination of dominated strategies and that between Perfect Bayesian Equilibrium and backward induction (Subgame Perfect Equilibrium).展开更多

The results showed a poor inhabitant of aquatic birds i.e. yellow wagtail (Motacillaflava); Black-winged Stilt (Himantopus himantopus); shelduck (Tadorna tadorna); Squacco heron (Ardeola ralloides); Moorhen (Gallinula chloropus); the bolti (Tilapia nilti). Equally, only four plant species were predominant in the lake area i.e. synonym (Tamarix aucheriana), a large perennial grass Phragmites australis, Athel pine or tamrisk (Tamarix aphylla) and synonym Zygophyllum simplex. Twelve fishes failed to survive longer than 45 minutes while another 6 fishes survived only in tributary water. Student T-Test biostatics analysis regarding the concentrations of the Total Dissolved Salts (TDS) in designated three parts of the lake showed significantly higher (P〈0.01〈0.0001) than acceptable limits for human usage, aquatic and natural habitat and perhaps for agricultural purposes. Similarly, the pHs of the waters were significantly alkaline (pH 8.9) and Eutrification of the lake waters clearly stand inappropriate for irrigation unless treated. The domestic pollutants were scattered almost all over the beaches as well as within the lake itself denoting unsafe of the lake as neither for natural habitats nor for tourism unless further attention is given by the municipal of Al-Jouf展开更多
