Spatial And Temporal Characteristics

With the further advent of the era of big data, the scale of social media data containing geolocation information is exploding, providing a new source of big data information and perspective for an in-depth study of the changing spatio-temporal and geographical characteristics of the current tourist population. This paper extracts data on popular attractions in the Tibet Autonomous Region using the HDBSCAN algorithm combined with the TF-IDF algorithm based on information on images with geotags shared by users in the Flickr image sharing site from 2005-2018. Social network analysis was used to explore the changes in the spatial and temporal characteristics of inbound tourism flows in Tibet. The results show that: (1) in terms of temporal characteristics, the number of inbound tourists shows obvious off-peak seasons, with relatively high sensitivity to the influence of economic, policy and infrastructure construction factors; (2) in terms of spatial distribution characteristics, the inbound tourism flow in Tibet shows an “axis-scattered” distribution. The core area is centred on Lhasa and extends in three directions: west, north and east along important roads.

Spatial And Temporal Characteristics

The study of the spatial and temporal characteristics of the gait of children and adolescents is an important task. The purpose of this study was to determine the spatial and temporal characteristics of the gait of children and adolescents of different age categories who systematically engage in sports.Methods. On motion capture complex Vicon in the Center for Collective Use "Three-dimensional study of the biomechanics of motion" of the Astrakhan State University, 43 children were examined: 22 children in the control group and 21 children in the study group.Results. Quantitative indicators of the spatial and temporal characteristics of the gait of children engaged in sports dancing were obtained and a comparative analysis of this data with the control group was carried out. An increase of walking speed and cadence, a decrease in the time of single and double support in male athletes in the 7-12 year old group was revealed; increased of walking speed and cadence, a marked decrease in the time of single support, a decrease in the limp index in female athletes in the 7-12 year old group; an increase the cadence in female athletes in the group of 12-15 years.Conclusions. Doing sport every day helps with the spatio-temporal changes of the walk among children and teenagers. The imbalance of the motor function is examined among girls, that doing sports between the age of 7-12, so that’s why it needs a special attention from doctors, traumatologist and orthopedists.

Abstract Starting in May 2014 an emerging Bluetongue (BT) serotype 4 (BTV-4) epizooty has affected the ruminant population of eleven countries from the Balkan Peninsula. Consequently, the veterinary services implemented various bio-security measures and a considerable discussion has been raised if future BTV surveillance and preventive measures should be taken in risk based zones and periods. Therefore, the objective of this work was to describe the spatial and temporal characteristics of the BTV-4 epizooty in the Balkan Peninsula from May 2014 to February 2015. We used the space-time permutation model of the scan statistic to identify the space-time disease clusters. The scan statistic was parameterized to a maximum temporal length of 150 days (duration of the epizooty in the Balkans in 2014) and a radius of 100 km as a maximum spatial cluster size (protection zone for BT). Results were significant (p < 0.05) to the maximum spatial size defined for the clusters. From the 6295 BT outbreaks the scan statistics identified 33 disease clusters in nine Balkan countries. The highest number of outbreaks occurred from September to November 2014.The earliest cluster was detected in Greece in July 2014 with a radius of 56 km. The latest cluster was detected in Croatia in February 2015 with a radius of 99,8 km. These results are a first description of the spatial and temporal characteristics of the 2014-February 2015 BT epizooty in the Balkans.

Abstract. An important feature of the relationships among ecosystem services (ES) is they have temporal and spatial patterns. The purpose of this research was to study the spatial and temporal characteristics of the synergies and trade-offs in ES in Guanzhong Basin and Hanzhoung Basin, as well as to compare the ES differences between the two basins. The spatio-temporal characteristics of the relationships among ES were analysed and compared from 1995–2014 for Hanzhong Basin, which has a good ecological environment, and the economically developed Guanzhong Basin, using linear relationship between grain output and NDVI (LRGO &amp; NDVI), the Carnegie–Ames–Stanford Approach (CASA), the integrated storage capacity method(ISCM), and the revised universal soil loss equation (RUSLE) model to simulate the four types of ES: food production (FP), net primary production (NPP), water retention (WR) and soil conservation (SC). The results of this study were as follows: (1) The trade-off relationships between FP and NPP in Guanzhong Basin and Hanzhong Basin were the most significant, and the trade-off relationship between FP and NPP in Guanzhong Basin (R = −0.40, P
