Determinants of visitor pro-environmental intentions on two small greek islands: Is ecotourism possible at coastal protected areas?
(2012)A relatively under-researched question is whether there is a possibility of influencing environmentally aware tourists regarding ecotourism at destinations that continue to develop under a pattern of mass 'seaside' tourism. ... -
Dimensional stabilisation of Scots pine (Pinus sylvestris L.) sapwood by reaction with maleic anhydride and sodium hypophosphite
(2021)Wood has the ability to absorb and desorb moisture, which can affect its dimensional size when in use. Limiting this can provide products with greater shape stability and less stresses on external coatings. One method that ... -
Distributed skip air index for smart broadcasting in intelligent transportation systems
(2012)Wireless data broadcast received a lot of attention from industries and academia in recent years. In any form of a push-based broadcast, access latency and tuning time are vital issues, and in order to address the tradeoff ... -
An eco-efficient and economical optimum evaluation technique for the forest road networks: the case of the mountainous forest of Metsovo, Greece
(2018)The sustainable forest management can be achieved only through environmentally sound and economically efficient and feasible forest road networks and transportation systems that can potentially improve the multi-functional ... -
Effect of misting on transpiration and conductances of a greenhouse rose canopy
(2001)The influence of greenhouse humidity control on the transpiration rate (lambdaE(c)). sensible heat flux (H-c) and bulk stomatal conductance (g(c)) of a soilless rose canopy (Rosa hybrida. cv. First Red) was studied in a ... -
Effects of satellite spatial resolution on gross primary productivity estimation through light use efficiency modeling
(2018)Terrestrial Gross Primary Productivity (GPP) describes the total amount of CO2 assimilated by plants in an ecosystem during photosynthesis and is considered the largest flux component of the global carbon cycle. One of the ... -
An efficient algorithm for bulk-loading xBR+-trees
(2018)A major part of the interface to a database is made up of the queries that can be addressed to this database and answered (processed) in an efficient way, contributing to the quality of the developed software. Efficiently ... -
An efficient flash-aware spatial index for points
(2018)Spatial database systems often employ spatial indices to speed up the processing of spatial queries. In addition, modern spatial database applications are interested in exploiting the positive characteristics of flash-based ... -
Efficient query processing on large spatial databases: A performance study
(2017)Processing of spatial queries has been studied extensively in the literature. In most cases, it is accomplished by indexing spatial data using spatial access methods. Spatial indexes, such as those based on the Quadtree, ... -
Estimation of the recharging rate of groundwater using random forest technique
(2020)Accurate knowledge of the recharging rate is essential for several groundwater-related studies and projects mainly in the water scarcity regions. In this study, a comparison between different methods of soft computing-based ... -
Farm management information system for fruit orchards
(2015)Fruticulture faces increasing market pressures that threaten its long-term viability. In the light of the real need to practically improve the environmental performance, to increase yield and to optimize product quality ... -
Fire performance and leach resistance of pine wood impregnated with guanyl-urea phosphate/boric acid and a melamine-formaldehyde resin
(2020)Scots pine (Pinus sylvestris L.) wood impregnated with guanyl-urea phosphate/boric acid and a melamine-formaldehyde resin exhibited considerably increased resistance to leaching, while sustaining superior fire retardancy ... -
Flower spatial variability in an apple orchard
(2009)Precision pomology is the application of site-specific management into orchards. Orchards produce high value crops and the application of site-specific management has high potential. Finding plant or soil characteristics ... -
Forecasting Winter Precipitation based on Weather Sensors Data in Apache Spark
(2021)The proposed paper introduces an approach providing weather information on winter precipitation types using machine learning techniques. The proposed methodology takes as input the data received from weather sensors and ... -
Full action instances for motion analysis
(2009)Motion analysis is an important component of surveillance,video annotation and many other applications. Current work focuses on the tracking of moving entities, the representation of their actions and the classification ... -
Furfurylation of tropical wood species with and without silver nanoparticles: Part I: Analysis with confocal laser scanning microscopy and FTIR spectroscopy
(2021)This work focused on the upgrading of non-durable tropical wood species originating from fast-growing plantations of Costa Rica. Modification of such tropical woods with furfuryl alcohol, although has not been broadly ... -
Grid-file: Towards to a flash efficient multi-dimensional index
(2015)Spatial indexes are of great importance for multidimensional query processing. Traditional data structures have been optimized for magnetic disks in the storage layer. In the recent years flash solid disks are widely ... -
The identification of several dipterocarpaceae and fagaceae trees by barcode dna coupled with high-resolution melting analysis
(2021)The loss of forests is a major environmental, social, and economic problem. The disappear-ance has been occurring to an extreme degree in many parts of Southeast Asia, including Thailand. Logging and clearing of forests ... -
Influence of whitening on greenhouse microclimate and crop energy partitioning
(2001)The influence of whitening a greenhouse roof on microclimate and canopy behaviour was studied during summer in a greenhouse located in the coastal area of eastern Greece. Measurements of microclimate variables, intercepted ... -
